Abstract Objective: To investigate the association between expression level of Von Hippel-Lindau(VHL) in pathological tissue and outcomes of platinum-based chemotherapy in non-small cell lung cancer (NSCLC) patients. Methods: The pathological samples of NSCLC patients were obtained for immunohistochemical staining to evaluate the expression level of VHL. Furthermore, their clinical data were collected and prognosis was traced by phone. The correlation between gene expression level and the hematotoxicity was evaluated by chi-square test. The influence of VHL expression level on the risk of hematotoxicity was tested by logistic regression model. The survival curve was plotted by Kaplan-Meier method and the survival rate between the two groups was compared by log-rank test. Results: A total of 110 NSCLC patients were enrolled in this study, the median follow-up time of these patients was 27.5 months. In the whole group, 31 patients had died by the last date of follow-up to get their survival information (Nov.10,2020), with a median survival time of 24.3 months. Though immunohistochemical analysis,we found that 59 patients(53.6%) had weak expression level of VHL or lack of expression in their tumor tissues,while 51 patients(46.4%) presented moderate or high expression. We found that the patients with weak expression of VHL in their carcinoma tissue or lack of expression had more opportunities to occur neutropenia after platinum-based chemotherapy(OR=0.264,95%CI=0.085-0.818,P-value=0.021).And the expression level of VHL was correlated with OS(Logrank test:P-value= 0.007,HR= 4.219,95%CI: 1.75-10.174, P-value=0.001), while not related with DFS(Logrank test:P-value=0.256,HR= 1.334,95%CI:0.642-2.769, P-value=0.440). Conclusion: The expression level of VHL gene in pathological tissue is related with Granulocytosis and leukocytotoxicity after platinum-based chemotherapy in NSCLC patients. It can be used as a biomarker to predict the risk of neutropenia and the prognosis of NSCLC patients.

Background: Immunotherapy combined with platinum-based chemotherapy is now the standard first-line treatment for non-small cell lung cancer (NSCLC) patients. However, limited evidence exists to show the efficacy of immunotherapy plus taxanes for patients who have progressed after platinum-based chemotherapy. Methods: The immunotherapy naïve patients with metastatic NSCLC who received anti-PD-1/PD-L1 monotherapy or combined with nab-paclitaxel after prior platinum-based chemotherapy from 2015 to 2018 in PLA General Hospital were identified. The progression-free survival, overall survival (OS), objective response rate (ORR), disease control rate (DCR) and safety were assessed. Results: Of 57 patients, 40 were treated with anti-PD-1/PD-L1 monotherapy and 17 were treated with anti-PD-1/PD-L1 plus nab-paclitaxel. With a median OS follow-up of 16.3 months, the nab-paclitaxel group showed significantly longer OS compared with the immune monotherapy group (median, 28.6 months versus 15.9 months, log-rank p = 0.020). When adjusted by covariates in COX proportional regression model, both the treatment group [ p = 0.009, hazard ratio (HR) 0.361; 95% confidence interval (CI) 0.168–0.773] and performance status ( p = 0.003, HR 0.372; 95% CI 0.192–0.721) demonstrated independent association with the longer OS from combination therapy. In addition, ORR was 23.5% (4/17) in the immune checkpoints inhibitors (ICIs) plus nab-paclitaxel group versus 13.5% (5/37) in immune monotherapy group ( p = 0.439), with a DCR of 88.2% (15/17) and 59.5% (22/37) ( p = 0.034), respectively. The incidence of grade 3/4 adverse events was 23.5% (4/17) in the combination group and 2.5% (1/40) in the immune monotherapy group. Conclusion: PD-1/PD-L1 inhibitor plus nab-paclitaxel resulted in significantly longer OS and higher response versus ICI single agent in metastatic NSCLC patients who have progressed after platinum-based chemotherapy. These findings need to be further explored by prospective studies.

Purpose Survival in patients with advanced non–small-cell lung cancer (NSCLC) who are treated with platinum-based chemotherapy is rather variable. Methylation-dependent transcriptional silencing of 14-3-3σ, a major G2-M checkpoint control gene, could be a predictor of longer survival. Patients and Methods A sensitive methylation-specific polymerase chain reaction assay was used to evaluate 14-3-3σ methylation status in pretreatment serum DNA obtained from 115 cisplatin-plus-gemcitabine–treated advanced NSCLC patients. Results 14-3-3σ methylation was observed in all histologic types of 39 patients (34%). After a median follow-up of 9.8 months, median survival was significantly longer in the methylation-positive group (15.1 v 9.8 months; P = .004). Median time to progression was 8 months in the methylation-positive group and 6.3 months in the methylation-negative group (log-rank test, P = .027). A multivariate Cox regression model identified only 14-3-3σ methylation status and Eastern Cooperative Oncology Group performance status as independent prognostic factors for survival. In an exploratory analysis, median survival for 22 methylation-positive responders has not been reached, whereas survival was 11.3 months for 29 methylation-negative responders (P = .001). Conclusion Methylation of 14-3-3σ is a new independent prognostic factor for survival in NSCLC patients receiving platinum-based chemotherapy. It can be reliably and conveniently detected in the serum, thus obviating the need for tumor tissue analysis.

e19011 Background: Non-small cell lung cancer (NSCLC) has a risk of death from brain metastases (BM) that exceeds potential mortality from extracranial disease progression. Erlotinib has been proved to be effective for NSCLC patients. We hold a study to evaluate value of erlotinib in preventing BM in stage III/IV NSCLC patients. Methods: Pathologically confirmed NSCLC stage III/IV patients were included and divided into erlotinib group and control group according to whether erlotinib administration (at least one month) in 1- or 2-line therapy or not. Stage IV patients with BM were excluded. Patients with any EGFR-TKI treatment were excluded from control group. Times of erlotinib administration to BM and to death or last follow-up were recorded for erlotinib group. Times of corresponding 1- or 2-line chemotherapy to BM and to death or last follow-up were recorded for control group correspondingly. Time to BM, 1- and 2-year incidence of BM were end points. Results: 140 patients were included (68 in erlotinib group and 72 in control group) and all clinical characteristics between two groups were balanced. At a median follow-up of 20.0 months, the median time to BM for all patients was 28.0 months (95% CI, 23.795-32.205 months). 1- and 2-year incidence of BM were 17.8% (95% CI, 10.744-24.856%) and 38.8% (95% CI, 27.236-50.364%) respectively. The median time to BM were 42.0 months (95% CI, 15.567-68.433 months) and 19.0 months (95% CI, 11.305-26.695 months) (P=0.028) for erlotinib group and control group. Erilotinib group has a lower BM incidence than control group (1-year: 14.4%, 95% CI: 4.992%-23.808%, vs 21.1%, 95% CI: 10.712%-31.488%, P=0.384; 2-year: 26.2%, 95% CI: 18.712%-33.688%, vs 50.2%, 95% CI: 34.128%-66.272%, P=0.005). Multivariate analysis shows interval to BM were longer for erlotinib group (HR, 2.531; 95% CI, 1.272-5.051; P=0.008) and stage III disease (HR, 2.093; 95% CI, 1.035-4.231; P=0.040). Conclusions: Erlotinib administration improves time to BM and 2-year incidence of BM of stage III/IV NSCLC patients. Erlotinib administration and stage III disease predicts lower incidence of BM in all patients.
