[Abstract] Objective To evaluate the effect of VPI on the survival of patients with postoperative stage ⅢA/N2M0 non-small cell lung cancer.Methods Using the Surveillance,Epidemiology,and Final Results(SEER) database,we screened patients with stage ⅢA/N2M0 non-small cell lung cancer who underwent surgery between 2010 and 2015.Cox proportional hazards regression is used to determine factors related to survival.Kaplan-Meier was used to analyze cancer-specific survival(CSS) and overall survival(OS) between the non-VPI group and the VPI group.Results Prognostic factors related to the VPI included race(P<0.001) and adenocarcinoma(P<0.001).VPI was an important independent prognostic factor of OS(HR,1.432;95% CI,1.082-1.573,P=0.006). Conclusion Our results show that VPI is a poor prognostic factor in patients with postoperative stage ⅢA/N2 non-small cell lung cancer.Studies have shown that chemotherapy significantly improves the overall survival rate of patients with stage ⅢA/N2M 0 non-small cell lung cancer after surgery,and reduces the related mortality of lung cancer,especially for non-VPI patients.

[Abstract] Objective To explore the expression levels of FOXQ1 and CyclinD1 in non-small cell lung cancer (NSCLC),and analyze their relationship with clinicopathological features and prognosis. Methods 196 cancer tissue samples and 30 adjacent tissue samples of NSCLC patients treated in our hospital from December 2014 to October 2017 were selected.The expressions of FOXQ1 and cyclinD1 protein in NSCLC tissues and adjacent tissues were detected by EnVisio immunohistochemistry.The expression levels of FOXQ1 and CyclinD1 in NSCLC and their relationship with clinicopathological parameters were analyzed.Spearman correlation was used to analyze the correlation between FOXQ1 and CyclinD1.Cox proportional hazards regression model was used to analyze the prognostic factors of NSCLC patients.Kaplan Meier survival curve was used to analyze the relationship between the expression of FOXQ1 and CyclinD and the prognosis. Results The high expression rates of FOXQ1 and cyclinD1 protein in NSCLC tissues were higher than those in paracancerous tissues (P<0.05).The high expression of FOXQ1 and CyclinDl in NSCLC was correlated with pathological differentiation,clinical stage and lymph node metastasis (P<0.05).Spearman correlation analysis showed that there was a positive correlation between foxq1 expression and CyclinD1 expression in NSCLC (P<0.05).Cox regression analysis showed that high expression of FOXQ1,CyclinD1 and FOXQ1+CyclinD1 were independent risk factors for progression free survival (PFS) and overall survival (OS) of NSCLC patients (P<0.05).Kaplan Meier analysis showed that the cumulative survival rates of PFS and OS in patients with high expression of FOXQ1 and CyclinDl were lower than those in other patients (P<0.05).The cumulative survival rates of PFS and OS in patients with high expression of FOXQ1 and CyclinDl were lower than those in patients with high expression of FOXQ1 and CyclinD1 alone (P<0.05).Conclusion FOXQ1 and CyclinD1 are highly expressed in NSCLC tissues,which are closely related to the occurrence,development and prognosis of the disease.FOXQ1 and cyclinD1 protein are positively correlated,the combined detection of both can better judge the prognosis of NSCLC patients.

[Abstract] Objective To explore the expression of crystallinalpha B(CRYAB) in elderly lung squamous cell carcinoma(LUSC) and investigate the relationship between its expression and clinical characteristics of LUSC.Methods Twenty cases of cancer tissues and adjacent tissues of LUSC patients from January 2014 to December 2016 were selected for qPCR detection and immunohistochemistry analysis(IHC) in tissue microarrays(59 LUCC samples and corresponding non-cancerous samples) were performed to characterize CRYAB expression in LUSC.Cox regression and KaplanMeier survival analyses were carried out to evaluate the prognostic indicator of LUSC.Results qPCR test showed that the expression value of CRYAB mRNA in LUSC was (4.456±1.512),which was significantly higher than that in adjacent tissue (2.944±0.4907),and the difference was statistically significant(P<0.05).Immunohistochemical detection showed that the protein expression of CRYAB in LUSC was significantly higher than that in the adjacent control group(P<0.05).Moreover,the expression level of CRYAB protein in LUSC was significantly correlated to T status(P<0.05).Univatiate and multivariate analysis of Cox regression showed that CRYAB expression could be identified as an independent prognosis factors for LUSC(P<0.05).High expression of CRYAB suggests poor prognosis.ConclusionCRYAB is highly expressed in LUSC patients.The data suggest that CRYAB expression is associated with malignant phenotypes of LUSCC and it may serve as a novel prognostic factor for LUSC.

[Abstract]Hepatocellular Carcinoma(HCC) is one of the most common malignant tumors,which ranks second in the mortality rate of malignant tumors in China.At diagnosis,most patients were in advanced stages already.They have lost surgical opportunities,and also achieved poor response from radiation therapy,chemotherapy,and traditional immunotherapy.In recent years,major advances have been made in anti-PD treatment for HCC,bringing new hope to advanced cancer patients.The anti-PD therapy for HCC has undergone the 1.0 era of anti-PD-1/PD-L1 monoclonal antibody monotherapy,the 2.0 era of combined molecular targeted drug application,and the 3.0 era of clinical application research stage of further combined locoregional therapy.With the development of the PD-1/PD-L1 inhibitors-based immunotherapy,the therapeutic effect of HCC has been further improved.The latest clinical research explores adoptive tumor-infiltrating lymphocytes therapy on the basis of immunotherapy 3.0,and the preliminary research has obtained good clinical efficacy,which also marks the advent of the era of HCC immunotherapy 4.0.
