Survival Analysis and Prognostic Factors for Peri-ocular Malignancies in Malaysia

@#Introduction: This study aims to determine the prognostic factors and survival outcomes of patients that underwent this surgery. Method: A retrospective review of 43 patients who underwent exenteration for periocular malignancies over a 14-year period was carried out. Patient demographics, tumour histology, treatment details, surgical margins’ status and post-operative survival were recorded. The survival outcome examined was the overall survival (OS) rate. Cox regression and Kaplan-Meier analysis were used to evaluate post-exenteration survival. Results: In total, 20 females and 23 males with a median age of 62 ± 17.3 years were identified. The most common indication for exenteration was basal cell carcinoma (20.9%), followed by squamous cell carcinoma (18.6%), adenocystic carcinoma (14%), malignant melanoma (14%) and sebaceous gland carcinoma (11.6%). The independent predictors for worse OS on multivariate analysis were Chinese ethnicity (adjusted hazard ratio [aHR] 4.95, p =0.017), sebaceous gland carcinoma (aHR 57.61 p=0.006), adenocystic carcinoma (aHR 45.87, p=0.008), clear surgical margins (aHR 5.41, p=0.025), receiving only chemotherapy (aHR 169.13, p=0.004), and receiving both adjuvant chemotherapy and radiotherapy (aHR 41.51, p=0.010). Conclusion: We recommend targeted public health initiatives for Chinese patients due to their increased mortality risk from peri-ocular malignancies. In addition, we advise comprehensive adjuvant therapy for all patients regardless of whether a clear surgical margin is achieved. Basal cell carcinoma and adenocystic carcinoma may also benefit from genetic research. We advocate more training for ophthalmologists to identify periocular malignancies earlier for better treatment options and increased chances of survival.

Early response to chemotherapy in children with Langerhans cell histiocytosis predicts long-term disease-free survival

Background: Langerhans cell histiocytosis (LCH) is a rare clonal malignancy of the monocyte-macrophage system. Patients with lesions in 搑isk organs� have significantly higher risk of mortality than patients with lesions limited to 搉on-risk� sites. The influence of early response to therapy on long-term survival in this heterogeneous multi-system disease was analyzed. Methods: During a 7-year period, we retrospectively analyzed the findings in 24 consecutive patients who required systemic chemotherapy for LCH [single system with multifocal bone involvement and multisystem involvement with or without risk organ (RO) involvement]. All patients were started on vinblastine and prednisolone. Progressive disease was treated with salvage protocols or targeted therapy. Positron emission tomography-computed tomography (PET-CT)/conventional CT based response assessment was performed at week 6 of chemotherapy, and if needed after week 12 of chemotherapy. Results: MFO bone, MS ROneg, and MS ROpos LCH was observed in 3, 4, and 17 patients, respectively. Age range of patients varied from 1 month�years (median = 18 months). The EFS and OS were 100% and 100% for MFO bone, 50% and 100%, respectively, for MS ROneg and 35% and 52%, respectively, for MS ROpos. OS was 93% and 100% for CR attained at 6 and 12 weeks respectively regardless of the risk status (P < 0.01). Conclusion: Rapid early response, that is, complete remission at 6 and 12 weeks was associated with significantly improved overall survival. In slow responders, early salvage with alternative regimens or targeted therapy may result in better outcomes

Expression of IGLL1 Gene and Its Clinical Significance in Pediatric T-ALL / 中国实验血液学杂志

OBJECTIVE@#To detect the relative expression of IGLL1 (immunoglobulin lambda-like polypeptide 1) mRNA in bone marrow of children with T-cell acute lymphoblastic leukemia (T-ALL), and analyze its correlation with the clinical characteristics and prognosis of the patients, so as to clarify the clinical significance of IGLL1 in pediatric T-ALL patients.@*METHODS@#A total of 56 pediatric T-ALL patients hospitalized in Children's Hospital of Soochow University from June 2012 to December 2017 and treated with CCLG-ALL 2008 regimen were selected. Transcriptome sequencing technology was used to detect the transcription level of IGLL1 gene in children with T-ALL. According to 25% of the IGLL1 transcription level (cutoff value:448), the enrolled children were divided into IGLL1 low expression group (17 cases) and IGLL1 high expression group (39 cases). Combined with clinical data, the correlation between the expression level of IGLL1 and prognosis of the patients was analyzed.@*RESULTS@#The comparative analysis showed that the transcription level of IGLL1 was not correlated with the clinical characteristics of the patients, such as sex, age, bone marrow blast, white blood cell (WBC) count at initial diagnosis. The 5-year OS rate of patients with high IGLL1 expression was significantly higher than that of patients with low IGLL1 expression (76.9%±6.7% vs 47.1%±12.1%, P =0.018). Further comparison of relapse-free survival (RFS) rate between the two groups showed that the 5-year RFS rate of patients with high IGLL1 expression was higher than that of patients with low IGLL1 expression, but the difference between the two groups was not statistically significant (P =0.095). Multivariate COX analysis was conducted on common clinical prognostic factors (age, sex, WBC count at diagnosis, prednisone response on the 7th day, bone marrow response on the 15th day after treatment) and IGLL1 expression level, and the results showed that IGLL1 expression (P =0.012) and prednisone response (P =0.017) were independent risk factors for overall survival in pediatric T-ALL patients.@*CONCLUSION@#In pediatric T-ALL, the OS rate of children with high expression of IGLL1 gene was significantly higher than that of children with low expression of IGLL1 gene, and the expression level of IGLL1 gene was an independent factor affecting the survival of children with T-ALL, which suggests that IGLL1 is a marker of good clinical prognosis of children with T-ALL.

Retrospective Clinical Study on Integrated Chinese and Western Medicine in Treatment of Limited-Stage Small Cell Lung Cancer / 中国结合医学杂志

OBJECTIVE@#To investigate the efficacy of integrated Chinese and Western medicine extending the progression-free survival (PFS) and overall survival (OS) of limited-stage small cell lung cancer (LS-SCLC) patients after the first-line chemoradiotherapy.@*METHODS@#The data of 67 LS-SCLC patients who received combined treatment of CM and Western medicine (WM) between January 2013 and May 2020 at the outpatient clinic of Guang'anmen Hospital were retrospectively analyzed. Thirty-six LS-SCLC patients who received only WM treatment was used as the WM control group. The medical data of the two groups were statistically analyzed. Survival analysis was performed using the product-limit method (Kaplan-Meier analysis). The median OS and PFS were calculated, and survival curves were compared by the Log rank test. The cumulative survival rates at 1, 2, and 5 years were estimated by the life table analysis. Stratified survival analysis was performed between patients with different CM administration time.@*RESULTS@#The median PFS in the CM and WM combination treatment group and the WM group were 19 months (95% CI: 12.357-25.643) vs. 9 months (95% CI: 5.957-12.043), HR=0.43 (95% CI: 0.27-0.69, P<0.001), respectively. The median OS in the CM and WM combination group and the WM group were 34 months (95% CI could not be calculated) vs. 18.63 months (95% CI: 16.425-20.835), HR=0.40 (95% CI: 0.24-0.66, P<0.001), respectively. Similar results were obtained in the further stratified analysis of whether the duration of CM administration exceeded 18 and 24 months (P<0.001).@*CONCLUSION@#The combination treatment of CM and WM with continuing oral administration of CM treatment after the first-line chemoradiotherapy for LS-SCLC patients produced better prognosis, lower risks of progression, and longer survival than the WM treatment alone.

Clinical characteristics and factors influencing the prognosis of patients with mucosal melanoma / 肿瘤研究与临床

Objective:To investigate clinical characteristics and factors influencing the prognosis of patients with mucosal melanoma.Methods:The clinical data of 49 patients with mucosal melanoma in Fujian Cancer Hospital from March 2012 to March 2022 were retrospectively analyzed, and their clinical characteristics and prognostic influencing factors were observed. Kaplan‐Meier method was used for survival analysis and Cox proportional risk model was used to analyze the prognostic influencing factors.Results:Female accounted for 61.2% (30/49) of all 49 patients with mucosal melanoma and the median age was 56 years (42-79 years). The most frequent primary tumor sites occurred in head and neck (42.9%, 21/49), followed by the reproductive system (32.7%, 16/49). At the time of initial diagnosis, 81.6% (40/49) of patients had no distant metastasis and 79.6% (39/49) of patients had normal levels of peripheral blood lactate dehydrogenase. The median overall survival time of 49 patients with mucosal melanoma was 39.5 months (95% CI 23.1-55.9 months). The median overall survival time of patients without distant metastasis at the time of initial diagnosis was significantly longer than that of patients with distant metastasis [46.5 months (95% CI 31.6-61.4 months) vs. 19.2 months (95% CI 0-42.2 months, P = 0.025]. There were no statistically significant differences in median overall survival time of patients with different gender, age at the time of initial diagnosis, primary tumor site, and the level of lactate dehydrogenase in peripheral blood at the time of initial diagnosis (all P > 0.05). The presence of distant metastasis at the time of initial diagnosis was an independent risk factor for the prognosis of patients with mucosal melanoma ( HR = 0.379, 95% CI 0.157-0.918, P = 0.032). Conclusions:Mucosal melanoma is more common in female. The most frequent primary tumor sites occur in head and neck. At the time of initial diagnosis, most patients have non‐distant metastasis and the normal level of peripheral blood lactate dehydrogenase. At the time of initial diagnosis, whether there is distant metastasis is an independent influencing factor for the prognosis of patients with mucosal melanoma.

Construction and evaluation of a nomogram prediction model for survival after radical surgical resection of intrahepatic cholangiocarcinoma based on the albumin-bilirubin index / 中华肝胆外科杂志

Objective:To construct a nomogram prediction model for survival after radical surgical resection of intrahepatic cholangiocarcinoma (ICC) based on the albumin-bilirubin index (ALBI), and to evaluate its predictive efficacy.Methods:From January 2016 to January 2020, 170 patients with ICC who underwent radical surgical resection at the People's Hospital of Zhengzhou University were retrospectively analyzed. There were 90 males and 80 females, aged (58.5±10.6) years old. Based on a ratio of 7∶3 by the random number table, the patients were divided into the training set ( n=117) and the internal validation set ( n=53). The training set was used for nomogram model construction, and the validation set was used for model validation and evaluation. Follow up was conducted through outpatient reexamination and telephone contact. The Kaplan-Meier method was used for survival analysis, and a nomogram was drawn based on variables with a P<0.05 in multivariate Cox regression analysis. The predictive strength of the predictive model was evaluated by analyzing the consistency index (C-index), calibration curve, and clinical decision curve of the training and validation sets. Results:Multivariate Cox regression analysis showed that carbohydrate antigen 19-9 (CA19-9) ≥37 U/ml ( HR=1.99, 95% CI: 1.10-3.60, P=0.024), ALBI≥-2.80 ( HR=2.43, 95% CI: 1.40-4.22, P=0.002), vascular tumor thrombus ( HR=2.34, 95% CI: 1.40-3.92, P=0.001), and the 8th edition AJCC N1 staging ( HR=2.18, 95% CI: 1.21-3.95, P=0.010) were independent risk factors affecting postoperative survival of ICC patients after curative resection. The predictive model constructed based on the above variables was then evaluated, and the C-index of the model was 0.76. Calibration curve showed the predicted survival curve of ICC patients at 3 years after surgery based on the model was well-fitted to the 45° diagonal line which represented actual survival. Clinical decision curve analysis showed that the model had a significant positive net benefit in both the training and validation sets. Conclusion:The nomograph model for survival rate after radical resection of ICC was constructed based on four variables: ALBI, CA19-9, vascular tumor thrombus, and AJCC N staging (8th edition) in this study. This model provided a reference for more accurate prognosis evaluation and treatment selection plan for ICC patients.

Clinical efficacy and toxic effects of prophylactic cranial irradiation in non-small cell lung cancer: a meta-analysis / 中华放射肿瘤学杂志

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.

Effect of non-alcoholic fatty liver disease on survival and risk factors in patients with hormone receptor-positive breast cancer / 中华内分泌外科杂志

Objective:To investigate the risk factors of non-alcoholic fatty liver disease (NAFLD) in patients with hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) breast cancer (HR+/HER2-BC) and the impact of NAFLD on the survival of patients.Methods:54 HR+BC patients were enrolled in this study. The liver fat accumulation was examined by magnetic resonance imaging (MRI). The patients were divided into two groups: non-NAFLD and NAFLD. Student's t test or Fisher's test was used to analyze the clinical indicators of the two groups. Logistic univariate and multivariate tests were used to analyze the clinical risk factors related to NAFLD. Receiver operating characteristic curve (ROC curve) was used to further analyze the sensitivity of clinical risk factors to predict the diagnosis of NAFLD. The Disease-free survival (DFS) and Overall survival (OS) of the two groups were analyzed by Log-rank (Mantel-Cox) test. Results:There were 22 NAFLD patients and 32 non-NAFLD patients diagnosed by MRI. Student's t test or Fisher's test showed that BMI, waist circumference, AST, ALT, GGT, TG, LDL and HDL were statistically different between the two groups (all P<0.05). Logistic univariate and multivariate analysis showed that AST ( OR=1.05, 95% CI: 1.02-1.10, P=0.007), GGT ( OR=1.04, 95% CI: 1.01-1.09, P=0.038), TG ( OR=1.03, 95% CI: 1.01-1.06, P=0.011) and HDL ( OR=1.06, 95% CI: 1.01-1.12, P=0.037) were the risk factors associated with NAFLD. ROC curve analysis showed that the combination of AST, GGT, TG and HDL had high sensitivity in predicting NAFLD (AUC=0.869, P<0.05). There was no difference in DFS ( HR=1.830, 95% CI: 0.983-3.409, P=0.057) or OS ( HR=2.482, 95% CI: 0.761-8.093, P=0.132) between the two groups. Conclusion:AST, GGT, TG and HDL are the independent risk factors for NAFLD in HR+BC patients during treatment, but concurrent NAFLD has no significant effect on DFS or OS.

Risk Factors and Prognosis of Cardiovascular Damage in Hypereosinophilia / 中国实验血液学杂志

OBJECTIVE@#To investigate the risk factors and prognosis of cardiovascular damage in hypereosinophilia (HE).@*METHODS@#The clinical data of 62 patients with HE in Gansu Provincial Hospital from January 2015 to December 2020 were retrospectively analyzed, including clinical characteristics and laboratory indicators, and the influencing factors of survival and prognosis were also analyzed.@*RESULTS@#In this study, there were 34 males and 28 females, with a median age of 53.5 (20-79) years, 35 patients without cardiovascular damage, 27 patients with cardiovascular damage, including 22 patients with abnormal electrocardiogram (ECG) (81.5%), 18 patients with abnormal echocardiography (ECHO) (66.7%), 9 patients with single ECG abnormality, 5 patients with single ECHO abnormality, and other 13 patients with multiple abnormalities. In cardiovascular damage group, peripheral white blood cell count, absolute value of eosinophils, troponin T (TNT), N-terminal pro-B-type natriuretic peptide (NT-proBNP), interleukin (IL)-4 and IL-5 levels at initial diagnosis were significantly higher than those in the non-cardiovascular damage group (P <0.01), while hemoglobin, IL-2 and interferon-γ levels were significantly lower (P <0.01). There were no significant differences in age, sex, course of disease, etiological classification, platelet count, serum creatine kinase, serum creatine kinase isoenzyme and lactate dehydrogenase between the two groups (P >0.05). The 5-year overal survival rate of patients with cardiovascular damage was 88.9%, and that of patients without cardiovascular damage was 100%, the difference was statistically significant (P =0.012). The 5-year event-free survival (EFS) rate of patients with cardiovascular damage was 59.3%, and the median time was 37 (21-52) months, while that of patients without cardiovascular damage was 80%, and the median time was 63 (51-74) months (P =0.002). Age (>60 years old), course of disease (>24 months), NT-proBNP (>3 000 pg/ml), TNT (>100 ng/L), elevated IL-4 and IL-5 were associated with EFS shortening in patients with cardiovascular damage, which were independent risk factors for EFS.@*CONCLUSION@#The EFS rate in HE patients without cardiovascular damage is significantly higher than patients with cardiovascular damage. Age, course of disease, NT-proBNP, TNT, IL-4 and IL-5 are independent risk factors affecting EFS of patients with cardiovascular damage.

Comparison of efficacy and safety of PN and RN in the treatment of stage T1b and T2a renal cell carcinoma / 现代泌尿外科杂志

【Objective】 To compare the efficacy, safety and survival of partial nephrectomy (PN) and radical nephrectomy (RN) in the treatment of clinical T1b and T2a renal cell carcinoma (RCC). 【Methods】 A total of 115 patients with stage T1b and T2a RCC treated during Apr.2014 and Jul.2017 were retrospectively analyzed. According to the different surgical methods, the patients were divided into PN group (n=55) and RN group (n=60). The clinical data and prognosis of the two groups were compared. 【Results】 There were no significant differences in the general clinical data and perioperative related factors between the two groups (P>0.05). The incidence of complications was significantly higher in PN group than in RN group (P=0.024), but there was no significant difference in serious complications (Clavien grade ≥3) (P>0.05). In terms of renal function recovery, there was no significant difference in serum creatinine between the two groups before operation (P>0.05), but the serum creatinine was significantly lower in PN group than in RN group on the 1st day, 3rd, 6th and 12th months after operation (P0.05). 【Conclusion】 Both PN and RN are safe and effective in the treatment of stage T1b and T2a RCC, and can achieve good oncological control effects. Compared with RN, PN can fully and effectively protect the postoperative renal function, but it causes more surgical complications. However, there is no significant difference in severe complications (Clavien grade ≥3).

Effects of preoperative ureteroscopy on intravesical recurrence after radical nephroureterectomy of upper tract urothelial carcinoma / 现代泌尿外科杂志

【Objective】 To investigate the effects of preoperative ureteroscopy (URS) on the intravesical recurrence (IVR) in patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). 【Methods】 The clinical data of 241 UTUC patients treated during May 2012 and Jan.2020 in the Second Hospital of Laozhou University were retrospectively analyzed. The patients were divided into URS before RNU group (URS group) and non-URS before RNU group (non-URS group). The cumulative IVR rate, progression-free survival (PFS) and overall survival (OS) after RNU were compared, and the survival curve was drawn. Cox proportional hazards models were used to assess risk factors affecting IVR. 【Results】 Of the 241 patients, 64 (26.6%) were included in the URS group and 177 (73.4%) in the non-URS group. In the URS group, 49 underwent biopsy and 15 did not. All patients were followed up for a median of 44 (3 to 122) months, with a median time to recurrence of 12 (3 to 56) months. IVR occurred in 18 patients (28.1%) in the URS group and 25 (14.1%) in the non-URS group. Kaplan-Meier survival analysis showed that the cumulative IVR rate was higher in the URS group than in the non-URS group (all P<0.05), regardless of whether patients had a history of bladder cancer (BC) or not, while PFS was lower in the URS group than in the non-URS group (P=0.007). Cox multivariate regression analysis showed that URS (P=0.031) and complicated renal pelvis tumor and ureteral tumor (P=0.004) were independent risk factors for IVR. 【Conclusion】 Preoperative URS increases the incidence of IVR in patients with UTUC, and routine preoperative use of URS is not recommended.

Development and validation of a nomogram for predicting survival outcomes in prostate cancer patients based on SEER database / 现代泌尿外科杂志

【Objective】 To establish and verify a nomogram model of overall survival (OS) of prostate cancer patients based on the SEER data. 【Methods】 A total of 12 642 patients diagnosed with prostate cancer during 2010 and 2015 were extracted from the SEER database. Patients were randomly divided into the model group (n=8 850) and validation group (n=3 792). The independent risk factors for OS were analyzed with univariate Cox proportional risk regression, lasso regression and multivariate Cox proportional risk regression. A nomogram was constructed to predict the 1-year, 3-year and 5-year OS. The prediction potential of the model was evaluated with the consistency index (C-index), calibration curve and receiver operating characteristic (ROC) curve. 【Results】 Multivariate Cox regression analysis showed that age, T stage, N stage, M stage, bone metastasis, liver metastasis and regional lymphadenectomy were independent risk factors for OS (P<0.05). The seven factors were used to construct an OS nomogram model. The C-index of the modeling set was 0.750, and the area under the ROC curve (AUC) at 1, 3 and 5 years were 0.77, 0.77 and 0.76, respectively;the C-index of the validation set was 0.765, and the AUC at 1, 3 and 5 years were 0.83, 0.79 and 0.76, respectively. The calibration curves of the modelling set and validation set showed a good agreement with the actual survival prediction rate. Risk stratification of patients based on the nomogram model showed that the OS of patients in the high-risk group was significantly lower than that in the low-risk group (P<0.001). 【Conclusion】 The nomogram can be used to predict the prognosis of prostate cancer patients, and is important for individualized treatment plans.

High preoperative neutrophile-lymphocyte ratio predicts poor prognosis of patients undergoing radical cystectomy for nonurothelial carcinoma of the bladder / 现代泌尿外科杂志

【Objective】 To investigate the predictive value of high preoperative neutrophile-lymphocyte ratio (NLR) for the prognosis of nonurothelial carcinoma of the bladder (NUBC) after radical cystectomy (RC). 【Methods】 Clinical and follow-up data of NUBC patients undergoing RC during Jan.2005 and Dec.2020 were collected. The optimal cut-off value of NLR was determined with the receiver operating characteristic (ROC) curve. The survival curve was drawn with Kaplan-Meier method to compare the differences in cancer specific survival (CSS) and overall survival (OS) between the high-NLR and low-NLR groups. The independent risk factors of CSS and OS were screened with Cox proportional hazard regression model. 【Results】 Of the 62 eligible cases,34 (54.8%) were diagnosed with adenocarcinoma,17 (27.4%) with squamous cell carcinoma, 6 (9.7%) with small cell carcinoma and 5 (8.1%) with sarcoma. Kaplan-Meier analysis results showed high NLR was associated with poor CSS (P=0.001) and OS (P<0.001). Cox regression results indicated that high NLR (HR=2.42, 95%CI: 1.12-5.23, P=0.025) and advanced pathologic tumor stage (HR=3.21, 95%CI:1.53-6.74,P=0.002) were independent risk factors of unfavorable CSS. Similarly, high NLR (HR=2.75, 95%CI: 1.35-5.56, P=0.005) and advanced pathologic tumor stage (HR=2.81, 95%CI:1.43-5.57, P=0.003) were independent risk factors of unfavorable OS. 【Conclusion】 As an independent risk factor of unfavorable CSS and OS in NUBC patients undergoing RC, high preoperative NLR is of great value in the prediction of long-term prognosis and may help to optimize individualized treatment.

Role of the criteria based on preoperative serological indexes of AFP and GGT in predicting long-term survival of patients with hepatocellular carcinoma after liver transplantation / 器官移植

Objective To evaluate the role of preoperative serological indexes in predicting long-term survival and tumor recurrence of hepatocellular carcinoma (HCC) patients after liver transplantation, aiming to explore its significance in expanding the Milan criteria. Methods Clinical data of 669 recipients undergoing liver transplantation for HCC were retrospectively analyzed. The optimal cut-off value was calculated by the receiver operating characteristic (ROC) curve. The risk factors affecting the overall survival and recurrence-free survival rates of HCC patients after liver transplantation were identified by univariate and multivariate regression analyses. The correlation between preoperative serum liver enzymes and pathological characteristics in HCC patients was analyzed. The predictive values of alpha-fetoprotein (AFP) combined with γ -glutamyl transferase (GGT) and different liver transplant criteria for the survival and recurrence of HCC patients after liver transplantation were compared. Results Exceeded Milan criteria, total tumor diameter (TTD) > 8 cm, AFP > 200 ng/mL and GGT > 84 U/L were the independent risk factors for the overall survival and recurrence-free survival rates of HCC patients after liver transplantation (all P < 0.05). Correlation analysis showed that preoperative serum GGT level was correlated with TTD, number of tumor, venous invasion, microsatellite lesions, capsular invasion, tumor, node, metastasis (TNM) stage, Child-Pugh score and exceeded Milan criteria (all P < 0.05). Milan-AFP-GGT-TTD (M-AGT) criteria were proposed by combining Milan criteria, TTD with serum liver enzyme indexes (AFP and GGT). The 5-year overall survival and recurrence-free survival rates of HCC recipients who met the M-AGT criteria (111 cases of exceeded Milan criteria) were significantly higher than those who met Hangzhou criteria (both P < 0.05), whereas had no significant difference from their counterparts who met the University of California at San Francisco (UCSF) criteria (both P > 0.05). Conclusions Preoperative serological indexes of AFP and GGT could effectively predict the long-term survival and tumor recurrence of HCC patients after liver transplantation. Establishing the M-AGT criteria based on serological indexes contributes to expanding the Milan criteria, which is convenient and feasible.

Establishment and validation of a nomogram for predicting prognosis of gastric neuroendocrine neoplasms based on data from 490 cases in a single center / 南方医科大学学报

OBJECTIVE@#To develop and validate a nomogram for predicting outcomes of patients with gastric neuroendocrine neoplasms (G-NENs).@*METHODS@#We retrospectively collected the clinical data from 490 patients with the diagnosis of G-NEN at our medical center from 2000 to 2021. Log-rank test was used to analyze the overall survival (OS) of the patients. The independent risk factors affecting the prognosis of G-NEN were identified by Cox regression analysis to construct the prognostic nomogram, whose performance was evaluated using the C-index, receiver-operating characteristic (ROC) curve, area under the ROC curve (AUC), calibration curve, DCA, and AUDC.@*RESULTS@#Among the 490 G-NEN patients (mean age of 58.6±10.92 years, including 346 male and 144 female patients), 130 (26.5%) had NET G1, 54 (11.0%) had NET G2, 206 (42.0%) had NEC, and 100 (20.5%) had MiNEN. None of the patients had NET G3. The numbers of patients in stage Ⅰ-Ⅳ were 222 (45.3%), 75 (15.3%), 130 (26.5%), and 63 (12.9%), respectively. Univariate and multivariate analyses identified age, pathological grade, tumor location, depth of invasion, lymph node metastasis, distant metastasis, and F-NLR as independent risk factors affecting the survival of the patients (P < 0.05). The C-index of the prognostic nomogram was 0.829 (95% CI: 0.800-0.858), and its AUC for predicting 1-, 3- and 5-year OS were 0.883, 0.895 and 0.944, respectively. The calibration curve confirmed a good consistency between the model prediction results and the actual observations. For predicting 1-year, 3-year and 5-year OS, the TNM staging system and the nomogram had AUC of 0.033 vs 0.0218, 0.191 vs 0.148, and 0.248 vs 0.197, respectively, suggesting higher net benefit and better clinical utility of the nomogram.@*CONCLUSION@#The prognostic nomogram established in this study has good predictive performance and clinical value to facilitate prognostic evaluation of individual patients with G-NEN.

Comparison of gefitinib plus chemotherapy versus gefitinib alone for advanced non-small-cell lung cancer: A meta analysis

Abstract This study aimed to perform a meta-analysis comparing the efficacy and safety of gefitinib in combination with chemotherapy versus gefitinib alone in patients with advanced Non-Small Cell Lung Cancer (NSCLC). We searched databases for clinical studies that reported the efficacy or safety of gefitinib plus chemotherapy in comparison with gefitinib alone. Raw data from included studies were extracted and pooled to calculate the Odds Ratio (OR) for Objective Response Rate (ORR) and Disease Control Rate (DCR), the Hazard Ratio (HR) for Progression-Free Survival (PFS) and Overall Survival (OS), and OR for complication ≥ Grade 3. A total of 10 studies containing 1,528 patients with NSCLC were identified and included in the analysis. Gefitinib plus chemotherapy showed significantly better efficacy in improving ORR (OR = 1.54; 95% CI [Confidence Interval], 1.13‒2.1; p = 0.006), DCR (OR = 1.62; 95% CI 1.14‒2.29; p = 0.007), PFS (HR=1.67; 95% CI 1.45‒1.94; p < 0.001) and OS (HR = 1.49; 95% CI 1.2‒1.87; p < 0.001) as compared with gefitinib alone. Consistent results were observed in the sub-population with positive EGFR mutation. The combination of gefitinib with chemotherapy had a significantly higher risk of complication (≥ Grade 3) with an OR of 3.29 (95% CI 2.57‒4.21; p < 0.001). The findings in the present study suggest that the combination of gefitinib with chemotherapy can provide better disease response and survival outcomes for patients with advanced NSCLC.

Gene mutation profiling and clinical significances in patients with renal cell carcinoma

Abstract Objectives The pathological mechanisms of patients with Renal Cell Carcinoma (RCC) remain defined. This study aimed to evaluate relationships between the landscape of gene mutations and their clinical significance in RCC patients. Methods Tissue and peripheral blood samples of 42 patients with RCC were collected and performed for the Next Generation Sequencing (NGS) with Geneseeq PrimeTM 425-gene panel probes. Their landscapes of gene mutation were analyzed. We also carried out an evaluation of Tumor-Node-Metastasis (TNM) staging, RENAL nephelometry score, surgery, and targeted drug treatment of patients. Then we compared the correlations of landscape in gene mutations and the prognosis. Results The most common gene alternations, including BAP1, PBRM1, SETD2, CSF1R, NPM1, EGFR, POLE, RB1, and VHL genes, were identified in tissue and blood samples of 75% of patients. EGFR, POLE, and RB1 gene mutations frequently occurred in relapsed and metastatic patients. BAP1, CCND2, KRAS, PTPN11, ERBB2/3, JAK2, and POLE were presented in the patients with > 9 RENAL nephelometry score. Univariable analysis indicated that SETD2, BAP1, and PBRM1 genes were key factors for Disease-Free Survival (DFS). Multivariable analysis confirmed that mutated SETD1, NPM1, and CSF1R were critical factors for the Progression Free Survival (PFS) of RCC patients with target therapy. Conclusions Wild-type PBRM1 and mutated BAP1 in patients with RCC were strongly associated with the outcomes of the patient. The PFS of the patients with SETD2, NPM1, and CSF1R mutations were significantly shorter than those patients without variants.

Supervivencia de pacientes con cáncer de mama y cirugía conservadora / Survival in Patients with Breast Cancer and Conservative Surgery

Introducción: En la actualidad la cirugía conservadora, más que una opción en el tratamiento quirúrgico del cáncer de mama, es la técnica quirúrgica de elección. Objetivo: Caracterizar la supervivencia de los pacientes con cáncer de mama operados con cirugía conservadora. Métodos: Se realizó un estudio multicéntrico, retrospectivo descriptivo de corte longitudinal, en el Hospital Universitario Clínico Quirúrgico "Arnaldo Milián Castro" y el oncológico "Celestino Hernández Robau", ambos de la ciudad de Santa Clara provincia Villa Clara, en el período comprendido desde enero del 2011 hasta diciembre del 2020. Resultados: La supervivencia global de los pacientes con cáncer de mama y cirugía conservadora en aquellos que presentaron eventos (fallecidos) fue mayor en los portadores de carcinoma ductal infiltrante con 9,3 años. En el caso del estadio tumoral predominó la supervivencia en aquellos pacientes que estaban en estadios Ia y IIa con 9,8 y 9,1 años, respectivamente. Según la inmunohistoquímica, el subtipo molecular con mejor supervivencia global fue el Luminal B con 9,2 años. En cuanto al tratamiento definitivo aplicado presentaron mayor supervivencia global aquellos pacientes que recibieron esquemas de quimioterapia+ radioterapia+ hormono terapia y quimioterapia+ radioterapia con 9,4 y 8,8 años, respectivamente. Conclusiones: Existe una mayor supervivencia global en aquellos pacientes con carcinoma ductal infiltrantes (NOS), estadios tumorales Ia y IIa, con subtipo molecular Luminal B según inmunohistoquímica y con tratamientos definitivos de quimioterapia+ radioterapia+ hormonoterapia(AU)

Introduction: Nowadays, conservative surgery, rather than an option for the surgical treatment of breast cancer, is the surgical technique of choice. Objective: To characterize the survival of patients with breast cancer operated on with conservative surgery. Methods: A multicenter, retrospective, descriptive and longitudinal study was carried out at Hospital Universitario Clínico Quirúrgico "Arnaldo Milián Castro" and "Celestino Hernández Robau" oncologic hospital, both in the city of Santa Clara, Villa Clara Province, in the period from January 2011 to December 2020. Results: The overall survival of patients with breast cancer and conservative surgery in those who presented events (died) was higher in those with infiltrating ductal carcinoma, accounting for 9.3 years. In the case of tumor stage, survival was predominant in those patients with stages IA and IIA, accounting for 9.8 and 9.1 years, respectively. Concerning immunohistochemistry, the molecular subtype with the best overall survival was Luminal B, accounting for 9.2 years. Regarding the applied definitive treatment, those patients who received chemotherapy-radiotherapy-hormone therapy and chemotherapy-radiotherapy schemes presented better overall survival, accounting for 9.4 and 8.8 years, respectively. Conclusions: Overall survival is higher in patients with infiltrating ductal carcinoma (not otherwise specified), tumor stages IA and IIA, molecular subtype Luminal B according to immunohistochemistry, and definitive treatments with chemotherapy, radiotherapy, hormone therapy scheme(AU)

Prognostic role of neutrophil-to-lymphocyte ratio to laryngeal squamous cell carcinoma: a meta-analysis / Papel prognóstico da relação neutrófilo-linfócito no carcinoma espinocelular da laringe: uma metanálise

Abstract Introduction New evidence suggests that the ratio of neutrophils to lymphocytes is associated with the prognosis of other carcinoma, but the ratio of neutrophils to lymphocytes in laryngeal squamous cell carcinoma remains controversial. Objective The objective of this meta-analysis was to clarify the prognostic effectiveness of the ratio of neutrophils to lymphocytes in laryngeal squamous cell carcinoma. Methods According to the meta-analysis of the free guide, we searched EMBASE, Pubmed, the Cochrane Library databases. The ratio of neutrophils to lymphocytes of laryngeal squamous cell carcinoma patients was evaluated using mean standard vehicle and confidence interval. The overall survival, disease-free survival and progression free survival of patients with laryngeal squamous cell carcinoma were expressed by standard mean carrier method and confidence interval. The risk ratio of 95% confidence interval was used as an evaluation index for patients with laryngeal squamous cell carcinoma. Results Eight studies, including 1780 patients, used a variety of different end values to classify the ratio of neutrophils to lymphocytes (range 1.78-4.0). Among the eight studies that reported risk ratio of the overall survival, the higher median value was 2.72, and 2 of 4 studies reported disease-free survival results. The critical value of ratio of neutrophils to lymphocytes and overall survival deterioration (risk ratio = 1.68, 95% confidence interval 1.43-1.99, p< 0.001), disease-free survival (risk ratio = 2.09, 95% confidence interval 1.62-2.6, p< 0.001) and progression free survival (risk ratio = 1.92, 95% confidence interval 1.75-2.10, p< 0.001) was associated with with laryngeal aquamous cell carcinoma. The ratio of neutrophils to lymphocytes had prognostic value for laryngeal squamous cell carcinoma. Conclusion The results of this meta-analysis showed that the increase of neutrophils to lymphocytes ratio was related to poor prognosis of laryngeal squamous cell carcinoma. The neutrophils to lymphocytes ratio may serve as a cost-effective prognostic biomarker of poor prognosis of laryngeal squamous cell carcinoma. More high-quality prospective trials are needed to assess the practicability of evaluating the ratio of neutrophils to lymphocytes in laryngeal squamous cell carcinoma.

Resumo Introdução Novas evidências sugerem que a relação neutrófilo-linfócito está associada ao prognóstico de vários carcinomas, mas a relação neutrófilo-linfócito no carcinoma espinocelular da laringe ainda permanece controversa. Objetivo Esclarecer a eficácia prognóstica da relação neutrófilo-linfócito no carcinoma espinocelular de laringe. Método De acordo com as diretrizes de metanálise, conduzimos uma busca nas bases de dados Embase, PubMed, e Cochrane Library. A relação neutrófilo-linfócito de pacientes com carcinoma espinocelular de laringe foi avaliado com a diferença de médias padronizadas e intervalo de confiança. A sobrevida global, sobrevida livre de doença e sobrevida livre de progressão de pacientes com carcinomaespinocelular de laringe foram expressas pelo método da diferença de médias padronizadas e intervalo de confiança. A razão de risco do intervalo de confiança 95% foi usada como um índice de avaliação para pacientes com carcinoma espinocelular de laringe. Resultados Oito estudos, que incluíram 1.780 pacientes, usaram uma variedade de valores finais diferentes para classificar a relação neutrófilo-linfócito (intervalo de 1,78-4,0). Entre os oito estudos que relataram a razão de risco de sobrevida global, o maior valor médio foi de 2,72 e 2 de 4 estudos relataram resultados com sobrevida livre de doença. O valor crítico de relação neutrófilo-linfócito e deterioração da sobrevida global (razão de risco = 1,68, intervalo de confiança 95% 1,43-1,99, p ˂ 0,001), sobrevida livre de doença (razão de risco = 2,09, intervalo de confiança 95% 1,62-2,6, p ˂ 0,001) e sobrevida livre de progressão (razão de risco = 1,92, intervalo de confiança 95% 1,75-2,10, p ˂ 0,001) foi associado com carcinoma espinocelular de laringe. A relação neutrófilo-linfócito tem valor prognóstico para carcinoma espinocelular de laringe. Conclusão Os resultados da metanálise mostraram que o aumento da relação neutrófilo-linfócito estava relacionado ao mau prognóstico do carcinoma espinocelular de laringe. A relação neutrófilo-linfócito pode servir como um biomarcador custo-efetivo de prognóstico do carcinoma espinocelular de laringe. Entretanto, mais estudos prospectivos de alta qualidade são necessários para avaliar a sua praticabilidade.

Feasibility and impact of screening for venous thromboembolism in treatment?naive lung cancer patients–Results of a prospective cohort study

Background: Venous thromboembolism (VTE) in cancer remains underdiagnosed. This prospective study aimed to evaluate the feasibility of screening for VTE in lung cancer (LC) patients. We assess the incidence of VTE, its risk factors, and effects on overall survival (OS). Methods: Consecutive treatment?naive LC patients were screened for deep venous thrombosis (DVT) with compression ultrasonography and pulmonary thromboembolism (PTE) with computed tomography pulmonary angiography (CTPA) at diagnosis and after 3 months of treatment. The incidence rate of VTE (DVT and/or PTE) was calculated. Risk factors associated with VTE were assessed using logistic regression analysis. All participants were followed?up to 1 year after enrollment. OS was compared in LC subjects with and without VTE, using the Cox proportional hazard analysis. Results: Around 301 subjects with LC (stages IIIB?IV accounted for 83.1%) were enrolled, of which 16 had VTE (5.3%). The incidence rate of VTE was 90 per 1000 person?years (PY). PTE was asymptomatic in 27.3% of cases while all DVT episodes were symptomatic. The incidence rate of asymptomatic PTE identified during the screening was 17 per 1000 PY. The median duration from LC diagnosis to the VTE event was 96.5 days. Median OS was significantly less in VTE patients [161 versus 311 days; P = 0.007] and death was attributable to VTE in 50%. After adjusting for covariates, VTE (hazard ratio [HR] = 2.1), smoking (HR = 1.7), and Eastern cooperative oncology group performance status ?2 (HR = 1.6) were independently associated with poor OS in LC. Conclusions: VTE occurs in approximately 1 in 20 newly?diagnosed patients with LC and is associated with decreased OS. Screening for PTE may be considered even in resource?limited settings
