RESUMEN
Introducción: La respuesta a las terapias en el cáncer de pulmón avanzado pudiera estar relacionada con determinados factores pronósticos como los índices inflamatorios. Objetivo: Evaluar la eficacia del anticuerpo monoclonal humanizado nimotuzumab en pacientes portadores de cáncer de pulmón no microcítico avanzado según índices inflamatorios. Método: Se realizó un estudio de evaluación longitudinal retrospectivo, en un universo de 498 pacientes mayores de 18 años, con diagnóstico citohistológico de cáncer de pulmón de células no pequeñas, en estadios avanzados, después de la primera línea de terapia oncológica, incluidos en ensayos clínicos multicéntricos promovidos por el Centro de Inmunología Molecular desde 2002 a 2018. Se aplicó la estadística descriptiva, se utilizó el software x-tile 3.6.1 para el test de Kaplan Meier; se consideraron diferencias significativas cuando p< 0,05. Resultados: En los pacientes analizados el nimotuzumab mostró beneficio terapéutico en el grupo de pacientes no progresores a la primera línea de tratamiento con quimioterapia o quimiorradioterapia, cuando tenían menor índice de neutrófilos/linfocitos (p= 0,017 y p= 0,027) y menor índice de plaquetas/linfocitos (p= 0,030 y p= 0,009). Conclusión: La selección de un paciente con menor índice inflamatorio beneficia la eficacia del tratamiento con el AcM humanizado nimotuzumab en el cáncer de pulmón avanzado no microcítico, la que se convierte en una herramienta predictiva de la respuesta al tratamiento.
Introduction: The response to therapies in advanced lung cancer could be related to certain prognostic factors such as inflammatory indices. Objective: To evaluate the efficacy of the humanized monoclonal antibody nimotuzumab in patients with advanced non-small cell lung cancer according to inflammatory indices. Method: A retrospective longitudinal evaluation study was carried out in a universe of 498 patients older than 18 years, with a cytohistological diagnosis of non-small cell lung cancer, in advanced stages, after the first line of oncological therapy, including in multicenter clinical trials promoted by the Center for Molecular Immunology from 2002 to 2018. Descriptive statistics were applied, the x-tile 3.6.1 software was used for the Kaplan Meier test, significant differences were considered when p< 0,05. Results: In the patients analyzed, nimotuzumab showed therapeutic benefit in the group of patients who did not progress to the first line of treatment with chemotherapy or chemoradiotherapy, when they had a lower neutrophil-lymphocyte index (p= 0,017 and p= 0,027) and a lower platelet-lymphocyte index (p= 0,030 and p= 0,009). Conclusion: Selecting a patient with a lower inflammatory index benefits the efficacy of treatment with the humanized mAb nimotuzumab in advanced non-small cell lung cancer, which becomes a predictive tool for response to treatment.
RESUMEN
The rapid progress on immunotherapy and targeted therapy has brought long-term survival benefits for locally advanced non-small cell lung cancer (NSCLC). The oncology community has also paid more attention to the local treatment for advanced NSCLC, especially for patients with limited metastatic lesions, also known as oligo-metastasis. Many studies have reported that oligo-metastatic NSCLC patients could benefit from the combination of local and systematic treatment, and even to be cured. In recent years, with the advances in radiation technology, stereotactic body radiation therapy (SBRT) has achieved precise high-dose radiotherapy for small target tumors. Currently, SBRT has been widely applied in the treatment of inoperable early lung cancer, and its application value and safety in patients with advanced lung cancer are also being actively explored. In this article, the research status, progress and future development direction of SBRT in the treatment of oligo-metastatic NSCLC were discussed.
RESUMEN
Objective:To conduct meta analysis to compare the effect of complete resection with or without postoperative radiotherapy (PORT) on survival in stage Ⅲ(N 2) non-small cell lung cancer (NSCLC). Methods:Relevant studies of the efficacy of PORT for stage Ⅲ(N 2) NSCLC were searched from Wanfang Data, PubMed, and Cochrane Library from January 2006 to January 2022. Literature screening, extraction of information and assessment of the risk of bias of the included literature was carried out by two independent researchers. Meta analysis was performed using R4.0.3 software. Results:A total of 12 publications consisting of 2992 patients were included, 1479 cases in the PORT group and 1513 cases in the control group. PORT improved the overall survival (OS) and disease free survival (DFS) compared to the control group. Fixed-effects model meta analysis of 6 randomized controlled trials showed that PORT did not significantly reduce the risk of death ( HR=0.98, 95% CI: 0.80-1.20). Fixed-effects model meta analysis of 6 retrospective studies showed that PORT improved prognosis ( HR=0.68, 95% CI: 0.59-0.79). PORT could improve OS of patients with multiple (station) metastasis of ipsilateral mediastinum and / or submandibular lymph nodes ( HR=0.89, 95% CI: 0.80-0.99). Conclusions:PORT could improve OS and DFS in stage Ⅲ(N 2) NSCLC. A trend towards benefit can be observed in the subgroup with multiple/multi-station N2 metastasis.
RESUMEN
Objective:To compare the adverse reactions, efficacy and survival rate of carbon ion beam irradiation in the elective lymph node (ENI) drainage area of locally advanced non-small cell lung cancer (LA-NSCLC) with relative biological effect (RBE) dose of 48 Gy using 16 and 12 fractions.Methods:A total of 72 patients with pathologically confirmed LA-NSCLC admitted to Wuwei Heavy Ion Center of Gansu Wuwei Tumor Hospital from June 2020 to December 2021 were enrolled and simple randomly divided into groups A and B, with 36 patients in each group. Patients in groups A and B were treated with carbon ion beam irradiation to the lymph node drainage area with 48 Gy (RBE) using 16 and 12 fractions. The acute and chronic adverse reactions, efficacy and survival rate were observed. The survival curve was drawn by Kaplan-Meier method. Difference test was conducted by log-rank test.Results:The median follow-up time was 13.9 (8.8-15.7) months in group A and 14.6 (6.3-15.9) months in group B. Sixteen (44.4%) patients were effectively treated in group A and 9 (25%) patients in group B. Thirty-four (94.4%) cases achieved disease control in group A and 30 (83.3%) cases in group B. Statistical analysis showed that the overall survival rate in group B was similar to that in group A ( χ2=1.192, P=0.275). Comparison of planning parameters between two groups showed CTV volume, D mean, V 5 Gy(RBE), V 20 Gy(RBE) and V 30 Gy(RBE) of the affected lung, cardiac V 20 Gy(RBE), V 30 Gy(RBE) and D mean, esophageal V 30 Gy(RBE), V 50 Gy(RBE), D max and D mean, D max of the trachea and spinal cord had no significant difference (all P>0.05). No grade 3 or 4 adverse reactions occurred in the enrolled patients during treatment and follow-up. No statistical differences were observed in the acute radiation skin reaction ( χ2=5.134, P=0.077), radiation esophagitis ( χ2=1.984, P=0.371), and advanced radiation pneumonia ( χ2=6.185, P=0.103) between two groups. Conclusions:The two dose fractionation modes of carbon ion therapy system are equally safe in the mediastinal lymphatic drainage area of LA-NSCLC, and the adverse reactions are controllable. The long-term efficacy still needs further observation.
RESUMEN
Objective:To investigate the role of prophylactic cranial irradiation (PCI) in non-small cell lung cancer (NSCLC) by meta-analysis.Methods:Studies published from January 1, 1980 to August 30, 2021 were searched systematically in PubMed, Embase, Cochrane Systematic Review database and China National Knowledge Infrastructure Database. The searching keywords included "non-small cell lung cancer", "randomized controlled trial", "prophylactic cranial irradiation" and "clinical trial". The data extracted from the above studies were analyzed using Review Manager 5.3 and Stata 12.0 software. Outcomes included the development of brain metastases (BM), overall survival (OS), disease-free survival (DFS), toxicity, and quality of life (QoL).Results:Ten trials, including 2005 NSCLC patients, met the inclusion criteria. Patients who underwent PCI had a significantly lower risk of BM than those who did not ( OR=0.29, 95% CI: 0.22-0.40, P<0.001). Compared with non-PCI group, DFS in PCI group was significantly increased ( HR=0.75, 95% CI: 0.63-0.89, P=0.001). However, there was no significant difference in OS ( OR=0.90, 95% CI: 0.69-1.18, P=0.45). In addition, the incidence of fatigue was significantly increased in the PCI group ( OR=2.64, 95% CI: 1.58-4.40, P<0.001). There was no significant difference in cognitive impairment between the PCI and non-PCI groups ( OR=3.60, 95% CI: 0.97-13.32, P=0.06). Conclusions:PCI is the standard treatment for NSCLC. Compared with non-PCI, PCI significantly reduces the incidence of BM and prolongs the DFS of NSCLC patients. The effect of PCI-related toxicity on the QoL and long-term OS needs further study.
RESUMEN
Objective:To investigate the value of preoperative enhanced CT combined with serum cytokeratin fragment 19 (CYFER21-1) and neuron-specific enolase (NSE) in the diagnosis of lymph node metastasis in patients with non-small cell lung cancer (NSCLC).Methods:160 patients with NSCLC admitted to Linyi Cancer Hospital from October 2018 to October 2021 were retrospectively selected. All patients received surgical treatment in our hospital, and 84 patients with lymph node metastasis (metastatic group) and 76 patients without lymph node metastasis (non-metastatic group) were confirmed after surgery. The features of enhanced CT images and serum CYFER21-1 and NSE levels were compared between the two groups before operation, and the value of each index in the diagnosis of lymph node metastasis in patients with NSCLC alone and in combination was analyzed by receiver operating characteristic (ROC) curve.Results:The proportions of patients with lesion diameter ≥3.0 cm, pleural depression, lymph node enlargement shown by CT, lymph node short diameter ≥10 mm, lymph node boundary ambiguity and lymph node enhancement in metastatic group were significantly higher than those in non-metastatic group, with statistical significance (all P<0.05). Serum CYFER21-1 and NSE levels in metastatic group were significantly higher than those in non-metastatic group, with statistical significance (all P<0.05). The area under curve (AUC) of CYFER21-1 and NSE levels in the diagnosis of lymph node metastasis in NSCLC patients were 0.652 and 0.845, respectively, and the diagnostic cut-off values were 4.81 ng/ml and 24.14 ng/ml, respectively. The sensitivity and specificity of CYFER21-1+ NSE+ enhanced CT in the diagnosis of lymph node metastasis in NSCLC patients were 91.67% and 94.74%. Conclusions:Preoperative enhanced CT is of certain clinical value in the diagnosis of lymph node metastasis in NSCLC patients. Combined with serum CYFER21-1 and NSE levels, enhanced CT can further improve the sensitivity and specificity of diagnosis.
RESUMEN
Objective:To analyze the effects of apatinib on quality of life and immune function in older adult patients with advanced non-small cell lung cancer.Methods:A total of 187 older adult patients with advanced non-small cell lung cancer admitted to Taizhou Cancer Hospital from January 2017 to January 2021 were included in this study. They were divided into the control group ( n = 93) and the observation group ( n = 94). The control group was treated with carboplatin combined with pemetrexed and the observation group was treated with apatinib based on carboplatin and pemetrexed. Sign and symptoms remission was compared between the observation and control groups. The levels of tumor markers, immune function, and quality of life score were compared between the two groups before and after treatment. Results:Total remission rate in the observation group was significantly higher than that in the control group (88.30% vs. 69.89%, χ2 = 9.59, P < 0.05). After treatment, carbohydrate antigen 125, carbohydrate antigen 50, and carcinoembryonic antigen in the observation group were (16.25 ± 5.47) μg/L, (15.23 ± 3.27) μg/L and (5.91 ± 2.66) mg/L, respectively, which were significantly lower than (21.49 ± 6.61) μg/L, (19.11 ± 3.48) μg/L and (10.14 ± 2.73) mg/L in the control group ( t = 5.91, 7.86, 10.73, all P < 0.05). The percentage of CD3 + and CD4 + cells, and the ratio of CD4 +/CD8 + cells in the observation group were (69.34 ± 8.85)%, (38.15 ± 6.52)%, (1.40 ± 0.33), respectively, which were significantly higher than (64.51 ± 8.74)%, (33.55 ± 6.33)%, (1.23 ± 0.25) in the control group ( t = -3.75, -5.36, -3.97, all P < 0.05). Quality of life score was increased in each group ( P < 0.001). The amplitude of increase in quality of life score was greater in the observation group compared with the control group ( P < 0.001). Conclusion:Apatinib can effectively reduce the level of tumor markers and improve immune function in older adult patients with advanced non-small cell lung cancer and improve quality of life.
RESUMEN
Objective:To investigate the risk factors of moderate to severe pain in patients with non-small cell lung cancer within 3 days after lobectomy.Methods:The clinical data of 297 patients with non-small cell lung cancer who underwent lobectomy in the Department of Thoracic Surgery, Sun Yat-sen University Cancer Center from December 2020 to June 2021 were retrospectively analyzed. A numerical rating scale was used to score the most severe pain within 3 days after surgery. Pain score ≥ 4 was defined as moderate to severe pain. The risk factors for moderate to severe pain were analyzed by binary Logistic regression. General linear model repeated measures and linear mixed models were used to analyze the trend of risk factors influencing postoperative pain with time.Results:The incidence of moderate to severe pain was 34.2% (102/297), 59.8% (178/297), 66.4% (198/297), and 28.2% (84/297) on days 0, 1, 2, and 3 after surgery respectively. The risk for moderate to severe pain was significantly higher in patients undergoing thoracotomy than patients undergoing thoracoscopic surgery on days 1 ( OR = 1.99, P = 0.009), 2 ( OR = 3.08, P < 0.001), and 3 ( OR = 3.88, P < 0.001) after surgery. However, the risk for moderate to severe pain in patients undergoing thoracotomy was slightly, but not significantly, higher than that in patients undergoing thoracoscopic surgery ( OR = 1.53, P = 0.087). The risk for moderate to severe pain was higher in female patients than male patients on day 2 ( OR = 1.62, P = 0.077), and in particular on day 3 after surgery ( OR = 2.39, P = 0.002). Prophylactic use of parecoxib significantly reduced the risk of moderate to severe pain on day 0 ( OR = 0.32, P = 0.004), 1 ( OR = 0.20, P < 0.001), 2 ( OR = 0.36, P < 0.001) and 3 ( OR = 0.56, P = 0.047). Conclusion:The incidence of moderate to severe pain on days 1 and 2 after lobectomy was relatively high in patients with non-small cell lung cancer. Patients undergoing thoracotomy have a higher risk of moderate to severe pain than those who underwent thoracoscopic surgery. Female patients have a higher risk for moderate to severe pain on days 2 and 3 after surgery than male patients. Prophylactic use of parecoxib can decrease the risk for moderate to severe pain in patients with non-small cell lung cancer.
RESUMEN
Objective:To investigate the prognostic value of urinary interleukin(IL)-8 in elderly patients with non-small cell lung cancer (NSCLC).Methods:The clinical data of 110 elderly patients with NSCLC treated in Beijing Hepingli Hospital from January 2018 to January 2019 were collected, and the relationship between urinary IL-8 and clinicopathological characteristics were analyzed. The best cut-off value was determined by receiver operating characteristic (ROC) curve. The factors affecting the survival and prognosis of elderly patients with NSCLC were determined by univariable and multivariable Cox proportional hazards regression models.Results:The best cut-off value of urine interleukin-8 for predicting prognostic of elderly patients with NSCLC was 26.08 ng/L, the specificity was 80.00%, the sensitivity was 84.60%. The level of urine IL-8 was related to neutrophil cell count, clinical stage and serum IL-8 level ( P<0.05). The results of Cox multivariate analysis showed that the age ( HR = 4.810, P = 0.000), serum soluble fragment of cytokeratin 19(CYFRA211) ( HR = 2.728, P = 0.017), clinical stage ( HR = 2.090, P = 0.014), urine IL-8 ( HR = 4.451, P = 0.000) were independent risk factors for survival of elderly patients with NSCLC. Conclusions:Urine IL-8 is an independent prognostic risk factor of survival of elderly patients with NSCLC, it can be used as one of the indicators to evaluate the survival prognosis of patients.
RESUMEN
Objective:To explore the efficacy of sequential and concurrent chemoradiotherapy in the treatment of advanced non-small cell lung cancer (NSCLC) in the elderly, and to analyze the influencing factors of prognosis and outcome.Methods:The clinical data of 195 elderly patients with advanced NSCLC admitted to Beijing Shijingshan Hospitaland and Beijing Shijitan Hospital from March 2015 to March 2018 were retrospectively analyzed. They were divided into the concurrent chemoradiotherapy (100 cases) and the sequential chemoradiotherapy (95 cases) according to different chemoradiotherapy regiments. The short-term efficacy, 3-year survival, influencing factors of prognosis and toxic and adverse effects of the two groups were compared.Results:The objective response rate in the concurrent chemoradiotherapy group was significantly higher than that in the sequential chemoradiotherapy group: 61.00%(61/100) vs. 44.21%(42/95), there was statistically difference ( χ2 = 5.51, P<0.05). The 2-year and 3-year survival rate in the concurrent chemoradiotherapy group were 52.00% and 23.00%, which were significantly higher than those in the sequential chemoradiotherapy group: 32.60%, 11.60%, there were statistically differences ( P<0.05). Multivariate analysis results showed that smoking, Karnofsky score<70, TNM stage Ⅲb, short-term efficacy and treatment methods/sequential chemoradiotherapy were independent risk factors ( P<0.05). The incidence of radiation esophagitis, bone marrow suppression and lung function damage in the concurrent chemoradiotherapy group were higher than those in the sequential chemoradiotherapy group: 45.00%(45/100) vs. 27.37% (26/95), 36.00%(36/100) vs. 22.11%(21/95), 48.00%(48/100) vs. 26.32%(25/95), there were statistically differences ( χ2 = 6.54, 4.55, 9.78; P<0.05). Conclusions:Concurrent chemoradiotherapy can improve the short-term efficacy, and improve the 2-year and 3-year survival rates in advanced NSCLC in elderly patients, but the adverse effects are significantly enhanced.
RESUMEN
Objective:To explore the potential categories of post-operative supportive care demand trajectory for patients with non-small cell lung cancer (NSCLC), analyze the influencing factors, and propose targeted interventions.Methods:This was a prospective observational study. A convenient sampling method was used to select 177 NSCLC patients who received surgical treatment in Shanghai Lung Hospital Affiliated to Tongji University from January 2021 to February 2022. The Supportive Care Demand Scale for cancer patients was used to investigate the level of patients′supportive care demand 1 day before operation, 3 days after operation, 1 day before discharge, 1 week after discharge, 1 month after discharge, and 3 months after discharge, and the potential growth model was used to identify the trajectory category and multi category Logistic regression analysis was used to explore the influencing factors.Results:Three supportive care demand trajectories were fitted out in this study, which were the continuous high demand group (46.33%), the slowly decreasing demand group (30.51%), and the low decreasing demand group (23.16%). With the potential category group 3, low demand reduction group as the reference category, Logistic regression analysis showed that high psychological distress, low social support, high disease stage, high comorbidities were more likely to enter the continuous high demand group ( OR = 0.826 to 18.526, all P<0.05), and high education level (college education and above and high school) were more likely to enter the slowly decreasing demand group ( OR = 6.076, 4.199, both P<0.05). Conclusions:The demand track of NSCLC patients for supportive care after surgery has population heterogeneity. Clinical medical staff should provide personalized social support and emotional support for patients with high disease stage, more complications and low education level in the early postoperative period.
RESUMEN
Objective:To investigate the grouping characteristics of psychological state symptom clusters in patients with non-small cell lung cancer during programmed death 1 (PD-1) monoclonal antibody combined with chemotherapy, and to analyze the predictors of different symptom cluster characteristics.Methods:This study was a cross-sectional study. In the form of a questionnaire, 171 patients with non-small cell lung cancer who received PD-1 monoclonal antibody combined with chemotherapy in Gansu Wuwei Tumor Hospital from March 2019 to March 2021 were selected as the research object by convenient sampling method. The general data questionnaire, Pittsburgh Sleep Quality Index, Cancer-Related Fatigue Survey Scale, Hospital Anxiety and Depression Scale, Physical Activity Measurement Scale for Cancer Patients, Distress Thermometer, and Quality of Life Measurement Scale for Lung Cancer Patients were used for investigation. The latent class model was fitted based on the evaluation results of physical fatigue, anxiety, depression, sleep quality and psychological distress in patients with non-small cell lung cancer during treatment. Latent class model analysis was performed on the scale results to establish a category group model. Logistic regression analysis was used to compare the demographic characteristics, disease stage, classification, and personality characteristics of patients in each group, and to explore the predictive indicators between different categories.Results:According to the symptoms of fatigue, anxiety, depression, sleep disorder and psychological distress in patients with non-small cell lung cancer during PD-1 monoclonal antibody therapy combined with chemotherapy, they were divided into two different categories. The group with high psychological symptoms accounted for 44.44% (76/171) and the group with low psychological symptoms accounted for 55.56% (95/171). The scores of physiological status, social/family status, emotional status, functional status, additional attention and physical activity in the quality of life scale of lung cancer patients with low psychological symptoms were 11.28 ± 5.62, 17.57 ± 4.31, 11.14 ± 3.27, 14.83 ± 5.24, 14.76 ± 4.03 and 88.61 ± 17.38, respectively. The scores were higher than those in the high psychological symptom group 17.82 ± 4.43, 10.76 ± 3.63, 18.62 ± 6.06, 9.34 ± 3.13, 26.26 ± 3.23, 58.04 ± 15.41, the differences were statistically significant ( t values were 10.36-15.84, all P<0.05); logistic regression analysis showed that personality traits [extroverted ( OR=0.08, 95 % CI 0.03-0.23, P<0.05), intermediate ( OR=0.16, 95 % CI 0.08-0.33, P<0.05)] and physical activity in cancer patients ( OR=0.91, 95 % CI 0.88-0.93, P<0.05) were predictors for distinguishing high psychological symptom group. Conclusions:There are obvious classification characteristics of psychological symptom clusters in patients with non-small cell lung cancer during PD-1 monoclonal antibody combined with chemotherapy. Different psychological interventions and nursing care are given according to different psychological symptom characteristics during treatment to improve the quality of life of patients.
RESUMEN
Objective:To explore the predictive value of neutrophil to lymphocyte ratio (NLR) and systemic immune-inflammation index (SII) of inflammatory markers of peripheral blood cells on the prognosis in the advanced non-small cell lung cancer (NSCLC) patients with immune therapy.Methods:The hematologic and clinical data of 58 patients with advanced non-small cell lung cancer who received the treatment of immune therapy in the First People's Hospital of Chuzhou of Anhui Province from January 2018 to June 2022 were retrospectively analyzed. X-tile software was used to calculate the optimal cut-off values of NLR and SII. All patients were divided into high and low groups according to the optimal cut-off values. The relationship between different NLR, SII and clinicopathological features, clinical efficacy, prognosis of the advanced non-small cell lung cancer patients with immune therapy were analyzed. Cox regression models were used to perform univariate and multivariate analyses of factors affecting patient prognosis.Results:The optimal cut-off values for NLR and SII were 3.2 and 546.5, respectively. There were statistically significant differences in regional lymph node metastasis ( χ2=5.03, P=0.025) and the number of metastatic sites ( χ2=11.60, P=0.001) between patients in the low-NLR group (NLR<3.2, n=26) and the high-NLR group (NLR≥3.2, n=32). There were statistically significant differences in location of the primary site ( χ2=8.34, P=0.004) between patients in the low-SII group (SII<546.5, n=28) and the high-SII group (SII≥546.5, n=30). The objective response rate (ORR) of the low-NLR group [50.00% (13/26) ] was higher than that of the high-NLR group [21.88% (7/32) ], and there was a statistically significant difference ( χ2=5.02, P=0.025) ; the disease control rate (DCR) of the low-NLR group [69.23% (18/26) ] was higher than that of the high-NLR group [50.00% (16/32) ], but there was no statistically significant difference ( χ2=2.19, P=0.139). The ORR of the low-SII group [53.57% (15/28) ] was higher than that of the high-SII group [26.67% (8/30) ]; The DCR of the low-SII group [67.86% (19/28) ] was higher than that of the high-SII group [33.33% (10/30) ], and there were statistically significant differences ( χ2=4.38 , P=0.036; χ2=6.91 , P=0.009). The median overall survival (OS) of patients in the low-NLR group (17.6 months) was longer than that of the high-NLR group (11.7 months), and there was a statistically significant difference ( χ2=11.07, P=0.001). The median OS of patients in the low-SII group (16.5 months) was longer than that of the high-SII group (12.3 months), and there was a statistically significant difference ( χ2=5.53, P=0.019). Univariate analysis showed that Eastern Cooperative Oncology Group (ECOG) score ( HR=2.20, 95% CI: 1.10-4.39, P=0.025), brain metastases ( HR=3.24, 95% CI: 1.61-6.50, P=0.001), the number of transferred sites ( HR=2.83, 95% CI: 1.44-5.57, P=0.003), NLR ( HR=3.22, 95% CI: 1.56-6.66, P=0.002) and SII ( HR=2.18, 95% CI: 1.12-4.24, P=0.021) were all independent influence factors affecting the prognosis of the advanced non-small cell lung cancer patients with immune therapy; multivariate analysis showed that brain metastases ( HR=2.91, 95% CI: 1.22-6.94, P=0.016), NLR ( HR=2.88, 95% CI: 1.17-7.13, P=0.022) and SII ( HR=3.63, 95% CI: 1.40-9.39, P=0.008) were all independent risk factors affecting the prognosis of the advanced non-small cell lung cancer patients with immune therapy. Conclusion:NLR and SII can be used as important indicators for predicting the efficacy of immunotherapy in the advanced NSCLC and elevated NLR and SII can indicate poor prognosis of patients.

Objective:To evaluate the safety of ensartinib in the treatment of anaplastic lymphoma kinase (ALK) -positive non-small cell lung cancer (NSCLC) in the real-world clinical setting.Methods:Clinical data of 2 221 patients with ALK-positive locally advanced or metastatic NSCLC who received ensartinib treatment (225 mg/d) from December 16, 2020 to December 16, 2021 were collected and analyzed to assess drug adverse reactions in all population including elderly patients (≥ 65 years old) .Results:Among the total 2 221 patients, 511 patients (23.01%) experienced adverse events, including 8 patients (0.36%) who experienced serious adverse events. Adverse events led to dose modification in 67 patients (3.02%) and discontinuation in 18 patients (0.81%). The common adverse events were rash (407/2 221, 18.33%), pruritus (41/2 221, 1.85%), constipation (41/2 221, 1.85%), and facial edema (31/2 221, 1.40%). Thirty-six patients (1.62%) experienced ≥grade 3 adverse events. After symptomatic treatment of 511 patients with adverse reactions, 50 patients (9.78%) were healed, 271 patients (53.03%) were improved, 120 patients (23.48%) were persisted, and 70 patients (13.71%) were unknown due to loss of follow-up or other reasons. Forty-three patients (1.94%) reported 57 unintended adverse reactions. Among the 599 elderly patients, 116 patients (19.37%) experienced adverse events, including 1 patient (0.17%) who experienced serious adverse events. Adverse events led to dose modification in 25 patients (4.17%) and discontinuation in 5 patients (0.83%). The common adverse events of elderly patients were rash (88/599, 14.69%), constipation (14/599, 2.34%), facial edema (12/599, 2.00%), and pruritus (10/599, 1.67%). Twelve patients (2.00%) experienced ≥grade 3 adverse events. Among the 116 elderly patients with adverse reactions following the symptomatic treatment, 11 patients (9.48%) were healed, 58 patients (50.00%) were improved, 28 patients (24.13%) were persisted, and 19 patients (16.39%) were unknown due to loss of follow-up or other reasons. During the treatment, 1 patient (0.05%) experienced grade 2 interstitial lung disease, and no patient died due to adverse events.Conclusion:Ensartinib has a favorable safety profile in the real-world populations, with the most frequent adverse events being rash, mostly mild, and low incidence of ≥grade 3 adverse events. Overall, adverse reactions were tolerable and manageable.
RESUMEN
Epidermal growth factor receptor (EGFR) -mutant advanced non-small cell lung cancer (NSCLC) was previously regarded as a cold tumor according to tumor immune microenvironment (TIME) . However, recent studies have found that EGFR-tyrosine kinase inhibitors (EGFR-TKIs) treatment can transform the host immunity from immunosuppressive to immunosupportive state, bringing new hope for immunotherapy. There are four main therapeutic strategies for patients after EGFR-TKIs acquired resistance: immunotherapy alone (Im) , immunotherapy plus chemotherapy (Im+C) , immunotherapy plus antiangiogenic drugs (Im+A) , and immunotherapy combined with antiangiogenic drugs and chemotherapy (Im+A+C) . Among them, the efficacy of Im is extremely limited, being significantly lower than that of chemotherapy alone, while there is still scarce evidence for the efficacy of Im+A with few clinical studies. The combination of Im+C and Im+A+C shows better efficacy than chemotherapy alone. Im+A+C has a superior clinical outcome to Im+C. Additionally, the EGFR L858R mutation subgroup benefits more from Im+C than the EGFR 19 del mutation subgroup. The T790M-negative subgroup has a greater benefit from Im+A+C than the T790M-positive subgroup. In general, the strategy of combining immunotherapy with chemotherapy and/or an antiangiogenic drug represents a novel and promising method for treating EGFR-mutant NSCLC after EGFR-TKI failure.
RESUMEN
Objective:To investigate the real-world efficacy of osimertinib and icotinib in metastatic non-small cell lung carcinoma (NSCLC) patients.Methods:A retrospective analysis was performed on clinical data of 151 newly-diagnosed patients with epidermal growth factor receptor (EGFR) -positive advanced NSCLC in Renmin Hospital of Wuhan University from March 2018 to May 2022. The patients were divided into osimertinib group ( n=53) and icotinib group ( n=98) according to treatment method. The objective response rate (ORR) , disease control rate (DCR) , progression-free survival (PFS) and overall survival (OS) were compared between the two groups. The factors influencing prognosis were analyzed by using Cox regression models. Subgroup analysis was performed according to metastatic site and EGFR mutation type. Results:ORR was 56.6% (30/53) and 59.2% (58/98) for patients in the osimertinib group and icotinib group, respectively, with no statistically significant difference ( χ2=0.09, P=0.759) . DCR was 83.0% (44/53) and 91.8% (90/98) for patients in the osimertinib group and icotinib group, respectively, with no statistically significant difference ( χ2=2.68, P=0.102) . The median PFS was 11.7 months and 11.8 months for patients in the osimertinib group and icotinib group, respectively, with no statistically significant difference ( χ2=0.06, P=0.802) . The median OS was not reached for patients in both the osimertinib group and icotinib group, with no statistically significant difference ( χ2<0.01, P=0.969) . The results of multivariate analysis showed that adrenal metastases ( HR=1.89, 95% CI: 1.04-3.41, P=0.036) was an independent prognostic factor for PFS. Gender ( HR=2.22, 95% CI: 1.08-4.58, P=0.031) and adrenal metastases ( HR=4.87, 95% CI: 1.76-13.46, P=0.002) were independent prognostic factors for OS. The results of the subgroup analysis showed that in patients with pleural metastases (median PFS: 11.7 months vs. 9.3 months, median OS: not reached vs. not reached) , adrenal metastases (median PFS: 8.7 months vs. 5.6 months, median OS: 20.0 months vs. 15.3 months) , 19DEL mutations (median PFS: 14.5 months vs. 13.3 months, median OS: not reached vs. 40.7 months) , the osimertinib group tended to have better survival outcomes. Conversely, in patients with contralateral lung metastases (median PFS: 8.3 months vs. 11.2 months, median OS: not reached vs. 40.7 months) , bone metastases (median PFS: 11.7 months vs. 11.8 months, median OS: not reached vs. 34.5 months) , liver metastases (median PFS: 8.7 months vs. 9.1 months, median OS: not reached vs. 23.8 months) , brain metastases (median PFS: 11.7 months vs. 15.3 months, median OS: 22.4 months vs. 35.3 months) and 21L858R mutations (median PFS: 9.5 months vs. 10.0 months, median OS: 22.4 months vs. not reached) , the icotinib group tended to have better survival outcomes, but with no statistically significant differences (all P>0.05) . Conclusion:Both osimertinib and icotinib have good therapeutic efficacy in patients with EGFR-positive advanced NSCLC, thus can be used as first-line treatment options.
RESUMEN
MET exon14 (METex14) skipping mutation is an independent driver gene in non-small cell lung cancer (NSCLC) . About 3%-4% of NSCLC patients carry METex14 skipping mutation. These patients have poor prognoses and poor responses to traditional chemotherapy and immunotherapy. Highly selective MET inhibitors such as capmatinib, tepotinib, savolitinib have shown good efficacy and safety data in clinical trials, which bring new treatment options for patients with METex14 skipping mutations.
RESUMEN
The morbidity and mortality of non-small cell lung cancer(NSCLC)are among the highest of all malignancies.The mechanisms concerning metronomic chemotherapy include anti-angiogenesis, immune microenvironment regulation, and cytotoxic effects, among others.As an alternative to traditional chemotherapy, metronomic chemotherapy has shown promising outcomes in the treatment of advanced NSCLC.Several clinical trials have explored the application of metronomic chemotherapy in the treatment of advanced NSCLC, either as a monotherapy or in combination with chemotherapy, anti-angiogenic therapy, targeted therapy or immunotherapy.This paper mainly reviews the mechanisms underlying metronomic chemotherapy and its clinical application in advanced NSCLC, in order to provide more evidence for the optimization of NSCLC treatment regimens.
RESUMEN
Objective:To investigate the predictive value of the epithelial cell proliferation(ECP)pathway genes for the prognosis of elderly non-small cell lung cancer patients treated with immunotherapy.Methods:A total of 106 elderly patients aged 70 years and over receiving immunotherapy in the POPLAR and OAK clinical trials were retrospectively analyzed in October 2022.According to the mutation status, patients were divided into an ECP pathway-related gene mutation group(ECP mutation group, n=25)and an ECP pathway-related gene non-mutation group(ECP non-mutation group, n=81). The primary endpoints were overall survival(OS)and progression-free survival(PFS). Differences in survival and efficacy between the two groups were compared, and subgroup analysis was performed on clinical factors and genes involved in the pathway.Pyclone was used to calculate the distribution of major clones and subclones in each patient, and differences in survival were compared.Results:Survival outcomes were worse in the ECP(+ )group than in the ECP(-)group(mOS: 10.9 months vs.17.1 months, HR=1.84, 95% CI: 1.09-3.08, P<0.05; mPFS: 2.8 months vs.4.2 months, HR=1.58, 95% CI: 1.00-2.51, P<0.05). Of all mutations in ECP pathway-related genes, mutations in the RB1 gene had a significant prognostic effect on all patients, with the negative prognostic effect especially prominent in ECP(+ )patients.Compared with ECP(-)patients, ECP(+ )patients had a shorter mOS(6.9 months vs.12.6 months, HR=3.14, 95% CI: 1.10-8.97, P=0.024). Ten patients had clonal mutations and 15 patients had sub-clonal mutations in ECP pathway-related genes and the former had a shorter mPFS than the latter(1.3 months vs.5.3 months, HR=3.23, 95% CI: 1.25-8.37, P=0.011). Conclusions:Gene mutations in the epithelial cell proliferation pathway are a negative prognostic factor in elderly non-small cell lung cancer patients receiving immunotherapy, and mutations located in the clonal cluster have a stronger impact on the prognosis.
RESUMEN
Objective:To investigate the efficacy and safety of recombinant human endostatin(Endostar)combined with platium-contained chemotherapeutic agents in advanced non-small cell lung cancer(NSCLC)patients over 60 years old.Methods:93 advanced NSCLC patients from January 2019 to June 2021 were selected as the research objects.The patients received three days of continuous intravenous infusion of Endostar(210 mg for 72 hours)combined with platinum-containing chemotherapy.The efficacy and toxicities were evaluated according to Response Evaluation Criteria in Solid Tumors(RECIST)version1.1 and National Cancer Institute Common Terminology Criteria for Adverse Events(NCI-CTCAE version 4.0), respectively.Follow-up data were obtained to perform the Kaplan-Meier survival analysis.Results:In our study, the objective remission rate(ORR)and disease control rate(DCR)were 38.7% and 78.5%, respectively.The median progression-free survival(PFS)and overall survival(OS)were 6.8 months and 16.5 months, respectively.A Multivariate analysis showed that tumor staging and TP53 mutation were independent prognostic factors related to PFS and OS in advanced NSCLC patients.Adverse reactions related to Endostar during treatment included arrhythmia in 2 cases(2.2%), myocardial ischemia in 1 case(1.07%)and bloody sputum in 1 case(1.07%), all of which were Grade 1 or Grade 2.Conclusions:The application of three days continuous intravenous infusion of Endostar combined with platium-contained chemotherapeutic agents is worthy to be recommended for clinical application in elderly patients with advanced NSCLC due to its high effective rate and survival advantage, as well as good safety.
