Abstract BACKGROUND Venous thromboembolism (VTE) is a common complication in patients with cancer. In general, patients with metastatic disease are at highest risk. Lung cancer belong to those tumor entities with a particularly high risk of VTE, ranging between 3–13.8%. However, little is known about the VTE rate in lung cancer patients with brain metastases. MATERIAL AND METHODS Our study was conducted in the framework of the Vienna Brain Metastasis Registry. Clinical data and VTE events during the course of the disease were recorded via retrospective chart review. In this analysis, non-small cell lung cancer (NSCLC) patients with a resection of brain metastases at the Medical University of Vienna between 2006 and 2010 were included. RESULTS In total, 69 NSCLC patients with brain metastases were analyzed. Overall, 69.6% (48/69) patients had an adenocarcinoma, 13% (9/69) a squamous cell carcinoma, 8.7% (6/69) a large cell carcinoma and 8.7% (6/69) other primary tumor histologies. After cancer diagnosis, 20.3% (14/69) patients developed VTE during the course of the disease. Of those, 85.7% (12/14) thromboembolic events occurred after the diagnosis of brain metastases. CONCLUSION Based on our data, patients with brain metastases from NSCLC have a very high VTE risk. Further investigations are needed in order to identify patients with distinct VTE risk profiles. Patients at high risk might potentially benefit from primary thromboprophylaxis over the high risk of intracerebral bleeding.

Background: In this study, we aim to establish a nomogram to predict the prognosis of non-small cell lung cancer (NSCLC) patients with stage I-IIIB disease after pneumonectomy.Methods: Patients selected from the Surveillance, Epidemiology, and End Results (SEER, N = 2,373) database were divided into two cohorts, namely a training cohort (SEER-T, N = 1,196) and an internal validation cohort (SEER-V, N = 1,177). Two cohorts were dichotomized into low- and high-risk subgroups by the optimal risk prognostic score (PS). The model was validated by indices of concordance (C-index) and calibration plots. Kaplan-Meier analysis and the log-rank tests were used to compare survival curves between the groups. The primary observational endpoint was cancer-specific survival (CSS).Results: The nomogram comprised six factors as independent prognostic indictors; it significantly distinguished between low- and high-risk groups (all P < 0.05). The unadjusted 5-year CSS rates of high-risk and low-risk groups were 33 and 60% (SEER-T), 34 and 55% (SEER-V), respectively; the C-index of this nomogram in predicting CSS was higher than that in the 8th TNM staging system (SEER-T, 0.629 vs. 0.584, P < 0.001; SEER-V, 0.609 vs. 0.576, P < 0.001). In addition, the PS might be a significant negative indictor on CSS of patients with white patients [unadjusted hazard ration (HR) 1.008, P < 0.001], black patients (unadjusted HR 1.007, P < 0.001), and Asian or Pacific Islander (unadjusted HR 1.008, P = 0.008). In cases with squamous cell carcinoma (unadjusted HR 1.008, P < 0.001) or adenocarcinoma (unadjusted HR 1.008, P < 0.001), PS also might be a significant risk factor.Conclusions: For post-pneumonectomy NSCLC patients, the nomogram may predict their survival with acceptable accuracy and further distinguish high-risk patients from low-risk patients.

Pembrolizumab has been approved as first-line treatment for advanced Non-small cell lung cancer (NSCLC) patients with tumors expressing PD-L1 and in the absence of other targetable alterations. However, not all patients that meet these criteria have a durable benefit. In this monocentric study, we aimed at refining the selection of patients based on the expression of immune genes. Forty-six consecutive advanced NSCLC patients treated with pembrolizumab in first-line setting were enrolled. The expression levels of 770 genes involved in the regulation of the immune system was analysed by the nanoString system. PD-L1 expression was evaluated by immunohistochemistry. Patients with durable clinical benefit had a greater infiltration of cytotoxic cells, exhausted CD8, B-cells, CD45, T-cells, CD8 T-cells and NK cells. Immune cell scores such as CD8 T-cell and NK cell were good predictors of durable response with an AUC of 0.82. Among the immune cell markers, XCL1/2 showed the better performance in predicting durable benefit to pembrolizumab, with an AUC of 0.85. Additionally, CD8A, CD8B and EOMES showed a high specificity (>0.86) in identifying patients with a good response to treatment. In the same series, PD-L1 expression levels had an AUC of 0.61. The characterization of tumor microenvironment, even with the use of single markers, can improve patients’ selection for pembrolizumab treatment.

IntroductionRecently, inhibition of programmed cell death 1 or its ligand has shown therapeutic effects on non-small cell lung cancer (NSCLC). However, the effectiveness of preoperative nivolumab monotherapy for stage I NSCLC remains unknown. The present study aimed to investigate the pathological response of preoperative treatment with nivolumab for clinically node negative but having a high risk of NSCLC recurrence.Methods and analysisThe Preoperative Nivolumab (Opdivo) to evaluate pathologic response in patients with stage I non-small cell lung cancer: a phase 2 trial (POTENTIAL) study is a multicentre phase II trial investigating efficacy of preoperative nivolumab for clinical stage I patients at high risk of recurrence. This study includes histologically or cytologically confirmed NSCLC patients with clinical N0 who were found on preoperative high-resolution CT to have a pure solid tumour without a ground-glass opacity component (clinical T1b, T1c or T2a) or a solid component measuring 2–4 cm in size (clinical T1c or T2a). Patients with epidermal growth factor receptor (EGFR) mutation (deletion of exon 19 or point mutation on exon21, L858R), anaplastic lymphoma kinase (ALK) translocation or c-ros oncogene 1 (ROS-1) translocation are excluded from this study. Nivolumab (240 mg/body) is administrated intravenously as preoperative therapy every 2 weeks for three cycles. Afterward, lobectomy and mediastinal lymph node dissection (ND 2a-1 or ND 2a-2) are performed. The primary endpoint is a pathological complete response in the resected specimens. The secondary endpoints are safety, response rates and major pathological response. The planed sample size is 50 patients. Patients have been enrolled since April 2019.Ethics and disseminationThis trial was approved by the Institutional Review Board of Hiroshima University Hospital and other participating institutions. This trial will help examine the efficacy of preoperative nivolumab therapy for clinical stage I NSCLC.Trial registration numberjRCT2061180016.
