ABSTRACT

Objective:To investigate the value of peripheral blood neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and serum lactate dehydrogenase (LDH) levels for predicting the occurrence of radiation pneumonia (RP) in small cell lung cancer.Methods:A total of 84 patients with small cell lung cancer who received image-guided radiotherapy in Xuzhou Cancer Hospital between September 2019 and September 2022 were retrospectively analyzed. They were divided into an RP group ( n = 25) and a non-RP group ( n = 59) according to whether RP occurred. Peripheral blood NLR and PLR and serum LDH levels were compared between the two groups before and after radiotherapy. The receiver operating characteristic curve (ROC curve) was used to analyze the value of peripheral blood NLR, PLR, and serum LDH levels for the diagnosis of RP in small cell lung cancer. Results:Before radiotherapy, there were no significant differences in peripheral blood NLR and PLR between the two groups (both P > 0.05). After radiotherapy, peripheral blood NLR and PLR in the RP group were (3.39 ± 0.81) and (129.06 ± 24.90), respectively, which were significantly higher than those in the non-RP group [(2.54 ± 0.71), (104.76 ± 26.26), t = 3.61, 3.83, both P < 0.05]. The NLR (2.86 ± 0.30) and PLR (110.07 ± 10.05) were the lowest in patients with grade 2 RP and they were highest in patients with grade 4 RP [(4.49 ± 0.63), (168.88 ± 14.11)]. The grade of RP was positively correlated with peripheral blood NLR and PLR. The sensitivity of peripheral blood NLR in the diagnosis of RP was 88.0%, the specificity was 66.1%, and the area under the curve (AUC) was 0.791. The sensitivity of PLR in the diagnosis of RP was 48.0%, the specificity was 94.9%, and the AUC was 0.735. The sensitivity of NLR combined with PLR in the diagnosis of RP was 92.0%, the specificity was 59.3%, and the AUC was 0.801. There was no significant difference in serum LDH levels between the two groups before and after radiotherapy (both P > 0.05). Logistic regression analysis showed that NLR and PLR were risk factors for RP in patients with small cell lung cancer ( OR = 2.309, 1.037; 95% CI: 1.061-5.024, 1.004-1.071). Conclusion:In patients with small cell lung cancer who develop RP, peripheral blood NLR, and PLR are markedly elevated compared with those in patients who do not develop RP, and combined detection of peripheral blood NLR and PLR has a high value for early diagnosis of RP in patients with small cell lung cancer.

ABSTRACT

Objective:To investigate the efficacy of tirellizumab combined with chemotherapy in the treatment of advanced non-small cell lung cancer and its effect on immune function and quality of life in patients.Methods:In this retrospective case-control study, we analyzed the clinical data of 104 patients with advanced (stages III and IV) non-small cell lung cancer who received treatment at Zhoushan Hospital between May 2021 and June 2022. These patients were divided into two groups: group A ( n = 52) and group B ( n = 52), based on the treatment methods utilized. Patients in group A received chemotherapy with gemcitabine plus cisplatin or pemetrexed plus cisplatin. Meanwhile, patients in group B were treated with tirellizumab combined with chemotherapy regimens of gemcitabine plus cisplatin or pemetrexed plus cisplatin, with 21 days as a treatment cycle. Both groups of patients received three cycles of treatment. The short-term efficacy was compared between the two groups. Additionally, serum levels of tumor markers, immune function indexes, quality of life score, and incidence of adverse reactions were compared between the two groups before and after treatment. Results:The short-term response rate in group B was significantly higher than that in group A [51.92% (27/52) vs. 32.69% (17/52), Z = 4.11, P < 0.001]. When compared with pretreatment levels, serum levels of tumor markers and the percentage of CD8 + cells decreased in both groups after treatment. Notably, the serum levels of tumor markers and the percentage of CD8 + cells were significantly lower in group B compared with group A (all P < 0.05). Moreover, after treatment, the percentage of CD4 + cells, the ratio of CD4 +/CD8 + cells, functional subscale, symptom subscale, and total score increased significantly compared with pretreatment levels (all P < 0.05) and were significantly higher in group B compared with those in group A (all P < 0.05). The incidence of adverse events in group B was significantly higher than that in group A [44.23% (23/52) vs. 21.15% (11/52), χ2 = 6.29, P = 0.012]. Conclusion:Tirelizumab combined with chemotherapy is effective for advanced non-small-cell lung cancer. The combined therapy can lower serum levels of tumor markers, restore immune function, and improve overall quality of life.

ABSTRACT

Objective:To analyze the prognostic value of MET, Cyclin D1, and MET gene copy number (GCN) for non-small cell lung cancer (NSCLC).Methods:This study included 61 patients with NSCLC who received treatment at the Enze Hospital, Taizhou Enze Medical Center (Group) between January 2018 and June 2019. The expression levels of MET and Cyclin D1 were determined using immunohistochemistry. MET GCN was evaluated using a quantitative polymerase chain reaction. Clinicopathological characteristics were compared among patients with different expression levels of these proteins. The Spearman correlation coefficient was used to assess the relationship between MET, Cyclin D1, and MET GCN. The Kaplan-Meier method was used to analyze survival rates. Univariate and multivariate Cox regression analyses were conducted to investigate the correlation between MET, Cyclin D1, and MET GCN and survival rates.Results:Thirty-six cases (59.02%) tested positive for MET, which was mainly expressed in the cytoplasm and membrane. Similarly, 36 cases (59.02%) were positive for Cyclin D1, which was mainly expressed in the cytoplasm. Patients with MET ( χ2 = 6.89, P = 0.009) and MET/Cyclin D1 ( χ2 = 4.05, P = 0.004) had a high proportion of poorly differentiated histology. Moreover, patients with MET GCN ≥ 3 had a relatively high proportion of lymph node metastasis ( χ2 = 8.11, P = 0.004) and TNM stages III-IV ( χ2 = 3.91, P = 0.048). Furthermore, patients with MET GCN ≥ 3/Cyclin D1 also had a high proportion of lymph node metastasis ( χ2 = 6.73, P = 0.009). MET was significantly associated with MET GCN ( r = 0.39, P = 0.002) and Cyclin D1 ( r = 0.39, P = 0.002), while MET GCN was significantly associated with Cyclin D1 ( r = 0.30, P = 0.017). The median survival time of patients with and without MET was 24.0 and 32.5 months, respectively, while the median survival time of patients with MET GCN ≥ 3 and < 3 was 11.0 and 30.5 months, respectively. Multivariate analysis showed that TNM stages III-IV, positive expression of MET, and MET GCN ≥ 3 were significantly associated with a high risk of death. Conclusion:The positive expression of MET and MET GCN ≥ 3 may be adverse prognostic factors in patients with NSCLC. The activation of the MET/Cyclin D1 signaling pathway could potentially contribute to the development and progression of NSCLC.

ABSTRACT

Objective:To investigate the effects of Kanglaite injection combined with chemotherapy on quality of life and myelosuppression in patients with non-small cell lung cancer (NSCLC).Methods:The clinical data of 60 patients with NSCLC who received treatment at Zhejiang Jinhua Guangfu Tumor Hospital from August 2018 to February 2022 were retrospectively analyzed. These patients were divided into an experimental group and a control group, with 30 patients in each group according to the treatment methods used. The patients in the experimental group received the Kanglaite injection in combination with chemotherapy using gemcitabine and cisplatin, whereas the patients in the control group were treated solely with chemotherapy with gemcitabine and cisplatin. The quality of life was evaluated using the Karnofsky Performance Status score. Before and after treatment, a comparison was made between the two groups in terms of Karnofsky Performance Status score, the incidence of adverse reactions (such as myelosuppression), and clinical efficacy.Results:After treatment, the disease control rate and objective response rate in the experimental group were 86.67% (26/30) and 60.00% (18/30), respectively, which were significantly higher than 60.00% (18/30) and 30.00% (9/30) in the control group ( χ2 = 4.18, 4.31, both P < 0.05). Prior to treatment, the Karnofsky Performance Status scores in the experimental and control groups were (70.68 ± 3.75) points and (70.29 ± 5.11) points ( t = 0.34, P = 0.790), respectively. After treatment, the Karnofsky Performance Status scores in the experimental group were significantly higher than those in the control group [(67.02 ± 5.87) points vs. (62.37 ± 3.59) points, t = -5.29, P < 0.05]. The incidence of adverse reactions in the experimental group was significantly higher than that in the control group [40.00% (12/30) vs. 36.67% (11/30), χ2 = 0.07, P = 0.790). Additionally, the incidence of myelosuppression in the experimental group was significantly lower than that in the control group [56.67% (17/30) vs. 86.67% (26/30), χ2 = 6.90, P = 0.030]. Conclusion:Compared with chemotherapy alone, Kanglaite injection combined with chemotherapy can effectively relieve the clinical symptoms of patients with advanced non-small cell lung cancer, leading to improved prognosis.

ABSTRACT

Objective:To explore the reasonable timing of radiotherapy for epidermal growth factor receptor ( EGFR) mutation-positive non-small cell lung cancer patients with brain metastasis in the era of third-generation targeted drugs. Methods:Clinical data of EGFR mutation-positive non-small cell lung cancer patients with brain metastasis who received first-line treatment with third-generation targeted drugs and stereotactic radiotherapy at Shanghai Armed Police Corps Hospital from September 2019 to May 2022 were retrospectively analyzed. According to the timing of radiotherapy before / after targeted drug resistance, all patients were divided into the early and salvage radiotherapy groups. The proportion of brain metastasis, physical fitness, complete response rate, objective response rate, delaying the progression of brain metastasis and overall survival (OS) were compared between two groups. Kaplan-Meier method was used for survival analysis, log-rank test was used for univariate prognostic analysis, and factors with P <0.1 were included in Cox multivariate analysis. Results:A total of 85 patients were included, including 51 (60%) cases receiving early radiotherapy. Patients who participated in early radiotherapy had a higher proportion of symptomatic brain metastasis (82% vs. 56%, P=0.013) and poorer physical fitness (Kanofsky performance score <70: 61% vs. 26%, P=0.002) compared to patients who underwent salvage radiotherapy. Early radiotherapy significantly improved the complete response rate of intracranial lesions (35% vs. 12%, P=0.015) and objective response rate (88% vs. 71%, P=0.041), delayed the progression of brain metastasis (median intracranial progression free survival: 23.0 months vs. 16.0 months, P=0.005; median intracranial secondary progression free survival: 31.0 months vs. 22.0 months, P=0.021), and improved OS (median OS: 44.0 months vs. 35.0 months, P=0.046). In multivariate analysis, diagnosis-specific graded prognostic assessment score <2.5, mutation of EGFR exon 21, and salvage brain radiotherapy were adverse prognostic factors for OS. Conclusion:In the era of third-generation targeted drugs therapy, early involvement of stereotactic radiotherapy in non-small cell lung cancer patients with brain metastasis can bring greater clinical benefits.

ABSTRACT

Objective:To evaluate the value of CEA, CYFRA21-1 and CA125 tests in opportunistic screening of non-small cell lung cancer (NSCLC) based on meta-analysis.Methods:The original research literatures on the diagnostic value of CEA, CYFRA21-1 and CA125 in Chinese NSCLC patients were searched from databases of PubMed, Embase, The Cochrane Library, CNKI, VIP, Database and Wanfang database from establishment to June 2023. The literature screening, data extraction and quality evaluation were carried out independently by two researchers. The quality evaluation tool of diagnostic accuracy studies was used to evaluate the quality of the literature. A summary receiver operating characteristic (SROC) curve was used to assess the overall effectiveness of the tests. The outcome stability and publication bias were detected by using sensitivity analysis and Deeks′ test.Results:A total of 23 studies met the inclusion and exclusion criteria were included. The results of meta-analysis showed that the overall sensitivity of CEA, CYFRA21-1 and CA125 alone in the diagnosis of NSCLC was relatively low, it was 0.49(95% CI: 0.43-0.55), 0.56(95% CI: 0.49-0.63) and 0.41(95% CI: 0.33-0.49), respectively. The overall sensitivity of the combined detection of the three markers for the diagnosis of NSCLC increased to 0.83(95% CI: 0.69-0.91), but the overall specificity decreased to 0.76(95% CI: 0.69-0.83). Conclusions:The single detection of CEA, CYFRA21-1 and CA125 is not recommended for screening NSCLC in population receiving physical examination. Although the sensitivity of the combined detection of CEA, CYFRA21-1 and CA125 for screening NSCLC is improved, but the specificity is decreased, the misdiagnosis rate is increased, so the screening effect is limited.

ABSTRACT

Objective:To assess the effectiveness and safety of beat chemotherapy in treating non-small cell lung cancer, and to investigate its anti-tumor molecular mechanism.Methods:In this study, we developed a subcutaneous tumor model of lung cancer in mice.The mice were subsequently divided into two groups: the beat chemotherapy group and the placebo group(negative control group).Throughout the treatment period, we monitored the changes in body weight and tumor size of the mice.At the conclusion of the treatment, we collected blood samples from the mice to conduct blood routine and biochemical examinations.Furthermore, we obtained tumor tissues from the mice to perform immunohistochemical staining and sequencing of the transcriptome.Results:The study found that beat chemotherapy could effectively delay the growth of lung cancer.The tumor tissues in the beat chemotherapy group were significantly smaller compared to the placebo group.The results of routine blood and blood biochemistry tests showed that the levels of red blood cells(RBCs), white blood cells(WBCs), alanine aminotransferase(ALT), aspartate aminotransferase(AST)and blood creatinine(Scr)were similar between the placebo group and the beat chemotherapy group.The values for RBCs, WBCs, ALT, AST and Scr in the placebo group were(6.97 ± 0.41)× 10 12/L, (13.26 ± 0.29)× 10 9/L, (33.33 ± 2.51)U/L, (235.33 ± 57.62)U/L and(20.67 ± 2.08)μmol/L, respectively.The corresponding values in the beat chemotherapy group were(6.87 ± 0.66)× 10 12/L, (12.59 ± 2.27)× 10 9/L, (38.67 ± 3.79)U/L, (225.33 ± 6.81)U/L and(20.33 ± 3.79)μmol/L.Statistical analysis showed no significant differences between the two groups( t=0.509, 0.209, 2.032, 0.299, 0.134, P=0.638, 0.845, 0.112, 0.780, 0.900).Furthermore, there were no signs of inflammatory infiltration or pathological changes in the liver, kidney, spleen, and lung tissues of the mice.Transcriptome analysis identified 68 differentially expressed genes, which were mainly associated with signal transduction and immunity.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis revealed the involvement of several signaling pathways, including the transforming growth factor β(TGF-β)signaling pathway, the interleukin-17(IL-17)signaling pathway, and the tumor necrosis factor(TNF)signaling pathway. Conclusions:The use of chemotherapy has been proven to be safe and effective in treating non-small cell lung cancer.It primarily functions by regulating tumor growth through various signaling pathways, including the TGF-β signaling pathway, IL-17 signaling pathway, and TNF.

ABSTRACT

Objective:To investigate the relationship between preoperative plasma fibrin degradation products (FDP) level and clinicopathological features of patients with completely resected non-small cell lung cancer (NSCLC).Methods:A retrospective case series study was performed. The clinical data of 521 patients who were pathologically diagnosed with NSCLC in Beijing Friendship Hospital Affiliated to Capital Medical University from January 2016 to December 2017 were retrospectively analyzed. Among 521 cases, 406 cases were postoperatively pathologically confirmed as non-lymph node and non-distant metastasis (non-metastasis group) and 115 cases were postoperatively pathologically confirmed as lymph node or distant metastasis (metastasis group). The preoperative FDP level and clinicopathological characteristics as well as the clinicopathological characteristics of NSCLC patients with different FDP levels were compared between the two groups. The correlation between preoperative FDP level and TNM staging was analyzed by using Spearman correlation analysis.Results:Among 521 NSCLC patients, 266 cases were female, 255 cases were male; the age [ M( Q1, Q3)] was 59 years (54 years, 65 years); 441 cases were adenocarcinoma and 70 cases were squamous cell carcinoma. The preoperative median FDP level was 2.78 mg/L (2.35 mg/L, 3.13 mg/L) and 2.99 mg/L (2.56 mg/L, 4.16 mg/L), respectively of NSCLC patients in non-metastasis group and metastasis group, and the difference was statistically significant ( Z = 6.13, P < 0.001). The preoperative FDP level was 2.56 mg/L (2.35 mg/L, 3.20 mg/L) and 2.99 mg/L (2.56 mg/L, 3.20 mg/L), respectively in the early-stage NSCLC (stage Ⅰ-Ⅱ) and advanced NSCLC (stage Ⅲ-Ⅳ) patients, and the difference was statistically significant ( Z = 8.42, P < 0.001). Spearman correlation analysis showed that preoperative FDP level was positively correlated with tumor diameter ( r = 0.287, P < 0.001). There was a positive correlation between preoperative FDP level and the number of metastatic lymph nodes in 115 patients with lymph node metastasis ( r = 0.679, P < 0.001). According to the preoperative median FDP (2.78 mg/L), all patients were divided into FDP ≤2.78 mg/L group and FDP >2.78 mg/L, and there were statistically significant differences in age, metastasis, tumor staging, tumor diameter, the metastatic number of lymph node and histological types of NSCLC patients in both groups (all P < 0.05). Conclusions:The increase of preoperative plasma FDP level may be related to the tumor metastasis and clinical stage of NSCLC patients

ABSTRACT

Objective:To investigate the efficacy of sintilimab combined with paclitaxel and docetaxel in the treatment of advanced non-small cell lung cancer (NSCLC).Methods:Prospective cohort study was performed. A total of 90 patients with advanced NSCLC receiving second-line treatment in Baotou Cancer Hospital from October 2019 to October 2022 were prospectively selected. All patients were divided into the study group (sintilimab combined with paclitaxel and docetaxel as second-line treatment, 45 cases) and the control group (paclitaxel or docetaxel alone, 45 cases) according to random number table method. The short-term efficacy, serum cytokine levels, quality of life and T-cell subsets of the two groups were compared. The survival of patients within 6 months was followed up. Kaplan-Meier method was used to analyze the overall survival (OS) of both groups, and log-rank test was used to make comparison among groups.Results:There were 25 males (55.56%) in the study group with the age of (63±5) years and 28 males (62.22%) in the control group with the age of (65±6) years. There were no statistically significant differences in the gender, age, Eastern Cooperative Oncology Group scores, the body mass (all P>0.05). The total effective rate was 88.89% (40/45) in the study group and 71.11% (32/45) in the control group, and the difference was statistically significant ( χ2 = 4.44, P = 0.035). The levels of serum vascular endothelial growth factor (VEGF) and carbohydrate antigen 125 (CA125) of both groups after treatment were lower than those before treatment (all P<0.001); the levels of VEGF and CA125 in the study group after treatment were lower than those in the control group [VEGF: (223±15) pg/ml vs. (289±15) pg/ml, t=20.82, P<0.001;CA125: (23±6) ng/ml vs. (75±4) ng/ml, t=51.28, P<0.001].Quality of life scale score, Karnofsky score of both groups after treatment were higher than those before treatment (all P<0.05); quality of life scale score and Karnofsky score in the study group after treatment were higher than those in the control group [quality of life scale score: (63±6) scores vs. (51±5) scores, t=10.29, P<0.001; Karnofsky score: (80.5±5.7) scores vs.(78.8±3.7) scores, t=1.70, P=0.041]. T-cell subsets indicators of both groups after treatment were higher than those before treatment (all P<0.001). T-cell subsets indicators in the study group after treatment were higher than those in the control group [CD3 + cell proportion: (68±5)% vs. (65±5)%, t=2.52, P = 0.014; CD4 + cell proportion:(42.5±1.7)% vs. (36.5±3.7)%, t=9.91, P<0.001;CD4 +/CD8 +: 1.78±0.54 vs. 1.46±0.27, t=3.56, P<0.001]. There was no significant difference in the incidence of adverse reactions between the two groups [11.11% (5/45) vs. 15.55% (7/45), χ2=0.39, P=0.534]. The follow-up time was 6 months. The OS in the study group was better than that in the control group ( χ2=3.86, P = 0.044). Conclusions:Sintilimab combined with taxoid chemotherapy drugs is effective in the second-line treatment of advanced NSCLC, and it improves immune function and shows a favorable safety.

ABSTRACT

Objective:To investigate the therapeutic effect difference between first-line treatment with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI) and chemotherapy in non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) rare mutation.Methods:A retrospective case-control study was performed. Data of NSCLC patients with rare EGFR mutation who were treated in Shanxi Province Cancer Hospital from January 2013 to October 2019 were retrospectively analyzed. EGFR mutations in living tissues or blood were detected by using amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) before first-line treatment. According to first-line treatment methods,they were divided into EGFR-TKI treatment group and chemotherapy group. Objective remission rate (ORR) and disease control rate (DCR) of both groups were compared. Kaplan-Meier method was used to draw progression-free survival (PFS) and the overall survival (OS) curves. Log-rank test was used for comparison among groups. Single-factor and multi-factor Cox proportional risk models were used to analyze the influencing factors of PFS and OS.Results:A total of 169 patients with EGFR rare mutations were included, and the age [ M (IQR)] was 63 years (12 years); there were 96 cases (56.8%) < 65 years and 73 cases (43.2%) ≥65 years; 70 (41.4%)males and 99 (58.6%) females; 55 cases (32.5%) had EGFR G719X mutation,45 cases (26.6%) had L861Q mutation, 17 cases (10.1%) had S768I mutation, and 52 cases (30.8%) had complex mutation; 55 cases (32.5%) received the first-line chemotherapy and 114 cases (67.5%) received the first-line EGFR-TKI treatment. In the chemotherapy group, ORR was 36.4% (20/55) and DCR was 85.5% (47/55); in EGFR-TKI treatment group, ORR was 72.8% (83/114) and DCR was 90.4% (103/114). The ORR of EGFR-TKI treatment group was higher than that of chemotherapy group ( χ2 = 20.70, P = 0.001), and there was no statistically significant difference in DCR between two groups ( χ2 = 1.76, P = 0.184). Subgroup analysis showed that ORR in EGFR-TKI treatment group with G719X, L861Q and complex mutations was higher than that of the corresponding mutations in chemotherapy group, and the differences were statistically significant (all P < 0.05), while there were no significant differences in DCR among subgroups (all P > 0.05). The median PFS time was 9.7 months (95% CI: 6.0-13.4 months) and 3.8 months (95% CI: 3.1-7.1 months), respectively in EGFR-TKI treatment group and chemotherapy group, and there was a statistically significant difference in PFS between the two groups ( P < 0.001). The median OS time was 25.6 months (95% CI: 18.0-37.9 months) and 31.7 months (95% CI: 18.0-42.8 months), respectively in EGFR-TKI treatment group and chemotherapy group, and there was no statistically significant difference in OS between the two groups ( P = 0.231). Multivariate Cox regression analysis showed that brain metastasis [with vs. without: HR = 2.306, 95% CI: 1.452-3.661, P < 0.001] and the first-line treatment methods (EGFR-TKI vs. chemotherapy: HR = 0.457, 95% CI:0.317-0.658, P < 0.001) were independent influencing factors for PFS of NSCLC patients with EGFR rare mutation; brain metastasis (with vs. without: HR = 2.087, 95% CI: 1.102-3.953, P = 0.024; unknown vs. without: HR = 2.118,95% CI: 1.274-3.520, P = 0.004) were independent influencing factors for OS of NSCLC patients with EGFR rare mutation. Conclusions:Compared with the first-line chemotherapy, EGFR-TKI first-line treatment could improve objective remission and PFS of NSCLC patients with EGFR rare mutation, while no OS benefit is observed.

ABSTRACT

Objective:To investigate the clinical efficacy and safety of deep hyperthermia combined with sintilimab and nab-PC (albumin-bound paclitaxel + carboplatin) regimen in the treatment of advanced squamous non-small cell lung cancer (NSCLC) with driver gene negative and programmed death-1 receptor ligand 1 (PD-L1) expression positive.Methods:A prospective case-control study was performed. A total of 84 advanced squamous NSCLC patients with driver gene negative and PD-L1 expression positive in Hebei Seventh People's Hospital from January 2020 to December 2022 were collected, and all patients were divided into the observation group and the control group according to the random number table method, with 42 cases in each group. The control group was given the treatment of sintilimab combined with nab-PC regimen, and the observation group was given deep hyperthermia on the basis of the control group. After 4 consecutive cycles of treatment, the short-term efficacy of the two groups was compared. The levels of serum tumor markers [carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCA), cytokeratin fragment 19 (CYFR21-1)], and the positive expression rates of immunohistochemistry markers [p40, p63, and cytokeratin 5/6 (CK5/6)] before and after treatment were compared between two groups. Functional Assessment of Cancer Therapy-Lung cancer module (FACT-L) scores, the adverse reactions and the long-term survival of the two groups were compared.Results:There were 26 males and 16 females in the observation group, and the age was (59±11) years; there were 22 males and 15 females in the control group, and the age was (58±11) years. The objective remission rate and the disease control rate were 71.43% (30/42), 90.48% (38/42), respectively in the observation group, and 50.00% (21/42), 80.95% (34/42), respectively in the control group; the objective remission rate in the observation group was higher than that in the control group, and the difference was statistically significant ( χ2 = 4.04, P = 0.044); and there was no statistically significant difference in the disease control rate of both groups ( χ2 = 1.56, P = 0.212). The levels of serum CEA, SCCA and CYFRA21-1, and the positive expression rates of p40, p63, and CK5/6 in the two groups after treatment were lower than those before treatment (all P < 0.05); and the scores of physiological status, functional status, additional concern in FACT-L scores and the total score of the scale after treatment were higher than those before treatment (all P < 0.05). There were no statistically significant differences in the incidence of adverse reactions including thrombocytopenia, neutropenia, leukopenia, anemia, fever of the two groups (all P > 0.05). The median progression-free survival (PFS) time was 6.5 months (95% CI: 3.82-12.75), 5.1 months (95% CI: 3.14-12.26),respectively in the observation group and the control group, and the difference in the median PFS time was statistically significantly of both groups ( χ2 = 4.21, P = 0.040). The median overall survival (OS) time was 12.9 months (95% CI: 6.25-15.46), 9.7 months (95% CI: 4.74-13.02), respectively in the observation group and the control group, and the difference in the median OS time was statistically significantly of both groups ( χ2 = 4.43, P = 0.035). Conclusions:Deep hyperthermia combined with sintilimab and nab-PC regimen in the treatment of advanced squamous NSCLC with driver gene negative and PD-L1 expression positive can effectively reduce the serum tumor markers levels and positive expression rate of immunohistochemical markers, improve the quality of life of patients, and increase the short-term and long-term efficacy.

ABSTRACT

Objective:To investigate whether chlorogenic acid can inhibit the proliferation, migration, invasion and promote apoptosis of lung cancer A549 cells by causing mitochondrial dysfunction through PI3K-Akt pathway.Methods:A549 cells were treated with chlorogenic acid at concentrations of 0, 25, 50, 100, 150, and 200 μg/ml for 48 h. CCK-8 assay was used to detect the cell proliferation rate and calculate the half maximal inhibitory concentration (IC 50). A549 cells were divided into three groups: control group, chlorogenic acid group (IC 50) and chlorogenic acid + 740-YP group (IC 50 chlorogenic acid +50 μg/ml 740YP). After 48 h of intervention, the cell migration distance was detected by cell scratch assay. Cell invasion assay was used to detect cell invasion ability. Cell cycle, apoptosis and mitochondrial membrane potential were detected by flow cytometry. The content of malondialdehyde (MDA) in cell supernatant was detected by enzyme-linked immunosorbent assay (ELISA). Western blotting was used to detect the protein expression of p-PI3K, p-Akt and Caspase3. Results:The IC 50 of chlorogenic acid to A549 cells was 57.45 μg/ml. The results of cell scratch assay showed that the 48 h migration distances of the control group, chlorogenic acid group and chlorogenic acid + 740YP group were (424.80±14.43), (289.67±18.93) and (402.22±17.99) μm, respectively. The results of cell invasion assay showed that the numbers of invasive cells after 48 h were 96.00±6.24, 35.33±7.64 and 83.00±2.00, and the results of flow cytometry showed that the 48 h apoptosis rates were (6.15±0.17) %, (54.63±0.72) % and (17.27±0.39) %, respectively, among the three groups with statistically significant differences ( F=105.98, P<0.001; F=90.62, P<0.001; F=8 321.99, P<0.001). Compared with the control group, the cell migration distances and invasive numbers of chlorogenic acid group and chlorogenic acid + 740YP group were decreased (all P<0.05), while the apoptosis rates were significantly increased (both P<0.001). Compared with chlorogenic acid group, the cell migration distance of chlorogenic acid + 740YP group increased ( P<0.001), the number of cell invasion increased ( P<0.001), and the apoptosis rate decreased ( P<0.001). The results of flow cytometry showed that the proportions of cells in G 0/G 1 phase in the control group, chlorogenic acid group and chlorogenic acid + 740YP group were (65.75±0.58) %, (55.84±0.78) % and (55.24±1.37) %, respectively. The proportions of G 2/M phase were (11.21±1.03) %, (20.23±0.62) % and (9.96±0.33) %, and the proportions of S phase were (23.04±0.49) %, (23.92±1.36) % and (34.80±1.15) %, respectively, with statistically significant differences ( F=111.02, P<0.001; F=181.26, P<0.001; F=113.05, P<0.001). Compared with the control group, the proportions of G 0/G 1 phase cells in chlorogenic acid group and chlorogenic acid + 740YP group decreased (both P<0.001), and the proportion of G 2/M phase in chlorogenic acid group increased ( P<0.001), and the proportion of S phase cells in chlorogenic acid + 740YP group increased ( P<0.001). Compared with chlorogenic acid group, the proportion of G 2/M phase cells decreased and the proportion of S phase cells increased in chlorogenic acid + 740YP group (both P<0.001). The results of mitochondrial membrane potential detection showed that the JC-1 fluorescence intensity of mitochondria in the control group, chlorogenic acid group and chlorogenic acid + 740YP group were 39.51±1.32, 10.05±0.19 and 21.85±1.45, respectively, with a statistically significant difference ( F=508.82, P<0.001). Compared with the control group, the fluorescence intensity of chlorogenic acid group and chlorogenic acid + 740YP group decreased (both P<0.001). Compared with chlorogenic acid group, the fluorescence intensity of chlorogenic acid + 740YP group increased ( P<0.001). ELISA results showed that the MDA contents of the control group, chlorogenic acid group and chlorogenic acid + 740YP group were (0.47±0.01), (0.61±0.01) and (0.56±0.01) nmol/ml, respectively, with a statistically significant difference ( F=162.30, P<0.001). Compared with the control group, MDA contents in chlorogenic acid group and chlorogenic acid + 740YP group increased (both P<0.001). Compared with chlorogenic acid group, MDA content in chlorogenic acid + 740YP group decreased ( P=0.001). Western blotting results showed that the relative protein expression levels of p-PI3K in the control group, chlorogenic acid group and chlorogenic acid + 740YP group were 1.01±0.33, 0.28±0.14 and 0.34±0.20, respectively. The relative protein expression levels of p-Akt were 1.00±0.16, 0.43±0.05 and 0.95±0.14, and the relative protein expression levels of Caspase3 were 1.00±0.04, 1.41±0.05 and 0.70±0.13, respectively, and there were statistically significant differences ( F=8.48, P=0.018; F=19.11, P=0.002; F=57.50, P<0.001). Compared with the control group, the expressions of p-PI3K and p-Akt protein in chlorogenic acid group decreased, and the expression of Caspase3 protein increased (all P<0.05). The expressions of p-PI3K and Caspase3 protein in chlorogenic acid + 740YP group decreased (both P<0.05). Compared with chlorogenic acid group, the expression of p-Akt protein in chlorogenic acid + 740YP group increased, and the expression of Caspase3 protein decreased (both P<0.05) . Conclusion:Chlorogenic acid may inhibit the PI3K-Akt pathway by reducing the phosphorylation of PI3K and Akt proteins, resulting in the damage of mitochondrial function and the accumulation of MDA, which eventually leads to the damage of lung cancer A549 cells function and the reduction of cells activity, and then promotes cells apoptosis.

ABSTRACT

Objective:To investigate the serum levels of miR-19b and miR-744-5p in patients with non-small cell lung cancer (NSCLC), and to analyze the clinical value of miR-19b and miR-744-5p in the diagnosis of NSCLC.Methods:A total of 226 NSCLC patients (NSCLC group) and 100 healthy people (control group) admitted to Jilin Cancer Hospital from August 2019 to August 2022 were selected as research objects. Quantitative real-time PCR was used to measure and compare the serum levels of miR-19b and miR-744-5p between the NSCLC group and the control group, and the relationships between the two indicators and different clinical and pathological characteristics of NSCLC patients were analyzed. The receiver operating characteristic curve was used to analyze the clinical value of miR-19b, miR-744-5p and their joint detection in the diagnosis of NSCLC.Results:Compared with the control group, the serum miR-19b level (3.86±1.25 vs. 1.06±0.41) in the NSCLC group significantly increased ( t=21.87, P<0.001), while the miR-744-5p level (1.80±0.48 vs. 5.75±1.69) significantly decreased ( t=32.36, P<0.001). The serum miR-19b levels in NSCLC patients with pathological types of adenocarcinoma, maximum tumor diameter ≥3 cm, medium to low differentiation, stage Ⅲ-Ⅳ, and with lymph node metastasis were higher than those in squamous cell carcinoma ( t=5.94, P<0.001), maximum tumor diameter <3 cm ( t=2.65, P=0.009), well differentiation ( t=4.33, P<0.001), stageⅠ-Ⅱ ( t=12.32, P<0.001), patients without lymph node metastasis ( t=8.13, P<0.001), while miR-744-5p levels were lower than those in squamous cell carcinoma ( t=8.27, P<0.001), tumor maximum diameter <3 cm ( t=5.34, P<0.001), well differentiation ( t=6.95, P<0.001), stageⅠ-Ⅱ ( t=11.40, P<0.001), patients without lymph node metastasis ( t=10.36, P<0.001). The area under the curve (AUC) of serum miR-19b combined with miR-744-5p in the diagnosis of NSCLC was 0.914 (95% CI: 0.841-0.959), with sensitivity and specificity of 90.9% and 84.0%, respectively. AUC was significantly than that of the single indicator detection of miR-19b (AUC=0.824, 95% CI: 0.770-0.869) and miR-744-5p (AUC=0.783, 95% CI: 0.709-0.838) ( Z=2.28, P=0.021; Z=2.36, P=0.017) . Conclusion:Serum miR-19b level of NSCLC patients is increased, miR-744-5p levels is decreased, and joint detection of serum miR-19b and miR-744-5p has high clinical value in the diagnosis of NSCLC.

ABSTRACT

Objective:To explore the impact of pembrolizumab combined with chemotherapy on angiogenesis and circulating endothelial cells in patients with advanced non-small cell lung cancer (NSCLC) .Methods:The retrospective analysis of clinical data from 121 patients diagnosed with advanced NSCLC who were admitted to the Second Affiliated Hospital of Xingtai Medical College from August 2021 to January 2023 was conducted. These patients were divided into a control group ( n=57) and an observation group ( n=64) based on the designated treatment protocol. Specifically, individuals in the control group received standard chemotherapy (cisplatin+paclitaxel), while those in the observation group underwent penpilimab therapy in conjunction with conventional chemotherapy. The comparative assessment encompassed short-term clinical efficacy, quality of life, immune function parameters, angiogenic factors [including endostatin, insulin-like growth factor 1 (IGF-1), and vascular endothelial growth factor (VEGF) ], circulating endothelial cells, and adverse reactions within the two groups. Results:After 6 courses of treatment, the objective response rate [67.19% (43/64) vs. 49.12% (28/57) ] and disease control rate [87.50% (56/64) vs. 70.18% (40/57) ] in observation group were higher than those in control group, with statistically significant differences ( χ2=4.06, P=0.044; χ2=5.52, P=0.019). The quality of life score of observation group [ (56.77±6.81) points] was significantly higher than that of control group [ (47.73±8.23) points], with a statistically significant difference ( t=6.61, P<0.001) ; The T cell subgroup CD3 + levels [ (63.59±9.00) % vs. (53.06±8.80%), t=6.49, P<0.001], CD4 + levels [ (46.54±8.20) % vs. (30.74±7.32) %, t=11.13, P<0.001] and CD4 +/CD8 + ratio (1.90±0.36 vs. 1.21±0.28, t=11.66, P<0.001) in observation group were significantly higher than those in control group, with statistically significant differences; Endostatin in observation group [ (48.99±3.43) μmol/L] was significantly higher than that in control group [ (31.35±3.87) μmol/L], with a statistically significant difference ( t=26.58, P<0.001), IGF-1 [ (102.31±20.35) μg/L vs. (134.98±19.02) μg/L] and VEGF [ (31.70±4.32) pg/ml vs. (58.71±5.99) pg/ml] were significantly lower in observation group than those in control group, with statistically significant differences ( t=18.73, P<0.001; t=28.14, P<0.001). The number of circulating endothelial cells in observation group [ (58.77±10.03) /ml] was significantly lower than that in control group [ (87.01±8.01) /ml], with a statistically significant difference ( t=17.20, P<0.001). During treatment, there were no statistically significant differences in the incidence of gastrointestinal reaction ( χ2=0.01, P=0.908), leukopenia ( χ2=0.64, P=0.424), thrombocytopenia ( χ2=0.28, P=0.597), anemia ( χ2=1.66, P=0.197), nephrotoxicity ( χ2=0.64, P=0.424), skin rash ( χ2=1.33, P=0.249) between the two groups. Conclusion:The combination therapy of pembrolizumab and chemotherapy for the treatment of advanced NSCLC has demonstrated noteworthy effectiveness. This regimen has the potential to enhance patients' immune functionality, ameliorate their overall quality of life, suppress angiogenesis, and exhibits a commendable profile of safety and reliability.

ABSTRACT

Objective:To compare the clinical efficacy of camrelizumab and sintilimab in the treatment of advanced non-small cell lung cancer (NSCLC) , and to explore its impact on tumor marker levels and immune function index, as well as to perform safety analysis.Methods:A total of 87 patients with advanced NSCLC who were treated in Hai'an People's Hospital of Jiangsu Province from May 2019 to May 2021 were selected as the research objects. According to the treatment scheme, the patients were divided into camrelizumab group ( n=41) and sintilimab group ( n=46) . The clinical efficacy, prognosis, tumor marker levels, immune function index and immune related adverse reactions of the two groups were compared. Results:There were no statistically significant differences in objective response rate [48.78% (20/41) vs. 39.13% (18/46) , χ2=0.82, P=0.365] or disease control rate [78.05% (32/41) vs. 71.74% (33/46) , χ2=0.46, P=0.499] in both camrelizumab and sintilimab group. The median progression-free survival (PFS) in the camrelizumab group was 9.1 months, and the median overall survival (OS) was 15.4 months. The median PFS in the sintilimab group was 9.7 months, and the median OS was 15.7 months. There were no statistically significant differences in median PFS and median OS between the two groups ( χ2=0.18, P=0.633; χ2=0.15, P=0.697) . Before treatment, there were no statistically significant differences in carcinoembryonic antigen (CEA) [ (47.68±8.12) ng/ml vs. (49.03±8.70) ng/ml, t=0.75, P=0.458], cytokeratin 19 fragment antigen 21-1 (CYFRA21-1) [ (18.06±3.41) ng/ml vs. (17.25±3.78) ng/ml, t=1.05, P=0.299], and carbohydrate antigen 125 (CA125) [ (72.26±21.06) U/ml vs. (74.03±22.10) U/ml, t=0.38, P=0.704] levels between the camrelizumab group and sintilimab group. After treatment, there were no statistically significant differences in CEA [ (28.11±7.68) ng/ml vs. (27.63±5.71) ng/ml, t=0.33, P=0.740], CYFRA21-1 [ (9.29±1.88) ng/ml vs. (9.06±1.80) ng/ml, t=0.15, P=0.814], and CA125 [ (61.39±21.22) U/ml vs. (60.51±11.03) U/ml, t=0.25, P=0.806] levels between the two groups, but CEA, CYFRA21-1, and CA125 levels decreased after treatment compared with those before treatment in both groups (all P<0.05) . Before treatment, there were no statistically significant differences in T cells CD4 + [ (41.15±3.24) % vs. (41.17±2.90) %, t=0.03, P=0.976], CD8 + [ (68.82±3.94) % vs. (70.06±4.08) %, t=1.44, P=0.154], and CD4 +/CD8 + (1.88±0.33 vs. 1.76±0.25, t=1.92, P=0.058) between the two groups.

ABSTRACT

Objective:To explore influencing factors affecting the prognosis of patients with advanced non-small cell lung cancer (NSCLC) receiving immunotherapy based on hematologic indexes, thus to construct and evaluate a nomogram prediction model.Methods:The clinical data of 80 patients with advanced NSCLC treated with programmed death-1 inhibitor monotherapy or combination regimen from January 2018 to June 2020 at the Affiliated Hospital of North China University of Science and Technology and Tangshan People's Hospital were retrospectively analyzed. Hematologic indexes at the baseline, the optimal remission and the progressive disease (PD) were collected separately, and independent influencing factors for patient prognosis were analyzed using Cox proportional hazards regression model. A nomogram prediction model was constructed based on the results of the multifactorial analysis, and the predictive performance of the model was evaluated by receiver operating characteristic (ROC) curve, concordance index (C-index) and calibration curves.Results:As of the follow-up cut-off date, of the 80 patients, 63 had PD, with a median overall survival (OS) of 16.9 months. Univariate analysis showed that, age ( HR=2.09, 95% CI: 1.17-3.74, P=0.013) , number of treatment lines ( HR=2.23, 95% CI: 1.21-4.12, P=0.010) , lymphocyte to monocyte ratio (LMR) at the baseline ( HR=0.75, 95% CI: 0.57-0.97, P=0.028) , D-dimer ( HR=1.00, 95% CI: 1.00-1.00, P=0.002) and lactate dehydrogenase (LDH) ( HR=1.01, 95% CI: 1.00-1.01, P=0.006) at the optimal remission, haemoglobin ( HR=0.97, 95% CI: 0.96-0.99, P<0.001) , D-dimer ( HR=1.00, 95% CI: 1.00-1.00, P=0.002) , C-reactive protein ( HR=1.01, 95% CI: 1.00-1.01, P=0.011) , albumin (ALB) ( HR=0.91, 95% CI: 0.87-0.96, P=0.001) , neutrophil to lymphocyte ratio (NLR) ( HR=1.16, 95% CI: 1.05-1.27, P=0.002) and LMR ( HR=0.62, 95% CI: 0.42-0.90, P=0.012) at the PD were all influencing factors for the prognosis of advanced NSCLC patients receiving immunotherapy. Least absolute shrinkage and selection operator regression were used to screen the variables for P<0.10 in the univariate analysis, and nine possible influencing factors were obtained, which were age, fibrinogen and LDH at the optimal remission, haemoglobin, D-dimer, C-reactive protein, LDH, ALB and LMR at the PD. Multivariate analysis of the above variables showed that, age ( HR=0.91, 95% CI: 0.86-0.97, P=0.004) , LDH ( HR=1.01, 95% CI: 1.00-1.01, P=0.013) and ALB ( HR=0.82, 95% CI: 0.67-0.99, P=0.041) at the PD were independent influencing factors for the prognosis of patients with advanced NSCLC who received immunotherapy. The area under curve of the nomogram predicting model based on the above indexes, 1- and 2-year OS rates of patients were 0.77 (95% CI: 0.65-0.89) and 0.75 (95% CI: 0.66-0.88) , respectively, and C-index was 0.71 (95% CI: 0.64-0.78) , the calibration curves showed good consistency between predicted and actual probability of occurrence. Patients in the low-risk group ( n=40) had a median OS of 29.9 months (95% CI: 22.5 months-NA) , which was significantly better than that of the high-risk group ( n=40) [13.4 months (95% CI: 11.4-23.5 months) , χ2=11.30, P<0.001]. Conclusion:Age, LDH and ALB at the PD are independent influencing factors affecting the prognosis of patients with advanced NSCLC receiving immunotherapy, and the nomogram model constructed based on the above indexes has good differentiation and calibration for predicting 1- and 2-year OS rates in advanced NSCLC patients receiving immunotherapy.

ABSTRACT

The effective local management of oligometastatic non-small cell lung cancer (NSCLC) has the potential to prolong patients' survival. The role of radiotherapy as a local treatment modality in patients with oligometastatic NSCLC, whether as first-line therapy or consolidation therapy, remains uncertain. Several studies have demonstrated that stereotactic ablative radiotherapy can offer clinical benefits for patients with oligometastatic NSCLC without increasing adverse reactions. Furthermore, the exploration of the potential synergistic effects of combining radiotherapy and immunotherapy on extending progression-free survival and overall survival in patients with oligometastatic NSCLC is also a topic worthy of attention.

ABSTRACT

Objective:To investigate the clinical efficacy and safety of programmed death protein 1 (PD-1) inhibitos combined with Fuzheng Kang'ai Decoction in patients with stage Ⅲ or Ⅳ non-small cell lung cancer (NSCLC) and identify factors that influence progression and prognosis in real world.Methods:Objective response rate (ORR), disease control rate (DCR), progression free survival (PFS), total survival time (OS) and adverse events of patients with advanced or metastatic NSCLC who received PD-1 inhibitors for the first time in the Department of Oncology, Guangdong Provincial Hospital of Chinese Medicine from August 2018 to March 2021 were retrospectively analyzed, and was prospectively followed up until September 2022. Kaplan-Meier method was used to plot survival curves and evaluate median PFS and median OS, while Cox proportional hazards regression model was used for multivariate analysis.Results:The final 66 patients were included in the study, with an ORR of 33.3% (22/66), a DCR of 86.4% (57/66), a median PFS of 9.90 months, and a median OS of 31.83 months. Univariate analysis showed that median PFS was associated with TNM stage, liver metastasis, PD-L1 expression level, lung immune prognostic index (LIPI), and traditional Chinese medicine syndrome types ( P values were 0.004, 0.033, 0.040, 0.004, and 0.001, respectively). Multivariate Cox regression analysis showed that TNM stage [ HR (95% CI)=4.179 (1.781, 9.804)], PD-L1 expression level 1%-49% [ HR (95% CI)=0.346 (0.127, 0.940)] or ≥ 50% [ HR (95% CI)=0.074 (0.019, 0.288)], LIPI [ HR (95% CI)=14.515 (2.939, 71.681)], and TCM characteristics of deficiency of yang qi [ HR (95% CI)=5.954 (2.093, 16.940)] were independent influencing factors for PFS. The overall and grade 3-5 treatment-related adverse events were 68.2% (45/66) and 9.1% (6/66), respectively. Conclusions:Fuzheng Kang'ai Decoction combined with PD-1 inhibitors is an effective and tolerable therapy for patients with advanced or metastatic NSCLC. TNM stage, liver metastasis, PD-L1 expression, LIPI and TCM characteristics are early predictors of clinical efficacy for patients with stage Ⅲ/Ⅳ NSCLC that receive traditional Chinese medicine combined with immunotherapy .

Objective To investigate the efficacy of Zorifertinib in first-line treatment of patients with untreated epidermal growth factor receptor(EGFR)mutation in non-small-cell lung cancer(NSCLC)with central nervous system(CNS)metastases.Methods Two patients received Zorifertinib as first-line treatment.The response of tumor treatment was evaluated by response evaluation criteria in solid tumors version 1.1(RECEST v1.1)and RANO criteria for brain metastases(RANO-BM).Results Case 1 had EGFR exon 19del mutation and multiple brain metastases at baseline.After 51.4 months of treatment with Zorifertinib,case 1 still maintained partial response(PR)in lung lesions and complete response(CR)in intracranial lesions.Case 2 had EGFR exon 19del mutation and a single brain metastasis at baseline.Case 2 achieved PR in lung lesions and CR in intracranial lesions during the treatment with Zorifertinib.After 13.7 months,lung disease progression(PD)and new single brain metastases occurred.The comprehensive evaluation was PD.Case 1 had three-grade treatment-related adverse events(TRAEs),including dry skin,and other TRAEs were rash,abnormal liver function and diarrhea.The TRAEs were generally controllable.Conclusion Zorifertinib has a good effect on controlling intracranial and extracranial lesions in patients with EGFR-mutated NSCLC with CNS metastases.The efficacy of Zorifertinib is consistent with the EVEREST study.Zorifertinib can be one of the first-line initial treatment options.
