[A Single Center, Retrospective Analysis of Prognosis in Non-small Cell Lung Cancer Patients with Peritoneal Carcinomatosis].

ABSTRACT: BACKGROUND:Peritoneal carcinomatosis is a rare clinical event in lung cancer and the prognosis is very poor. There are limited data on what factors predict peritoneal progression and affect the outcome. The aim of this study is to investigate investigate the factors associated with peritoneal carcinomatosis. METHODS:The patients with non-small cell lung cancer (NSCLC) from the Department of Medical Oncology and Radiation Sickness, Peking University Third Hospital were eligible for retrospective analysis between August 2010 and August 2018. Clinical factors such as age, gender, histology, pleural effusion and gene mutations with epidermal growth factor receptor/anaplastic lymphoma kinase/ROS proto-oncogene 1 receptor tyrosine kinase (EGFR/ALK/ROS1) were analyzed. Overall survival (OS) was calculated by the Kaplan-Meier method. RESULTS:1.44% (12/836) patients in this study developed peritoneal carcinomatosis and 12 patients with adenocarcinoma had metachronous NSCLC diagnosis and PC. Malignant pleural effusion rates at baseline and at PC diagnosis were separately 50% (6/12) and 100.0% (12/12). Among the 12 patients, 9 patients harbored EGFR/ALK/ROS1 mutation. The outcome of patients with EGFR/ALK/ROS1 mutation was significantly better than that of patients without EGFR/ALK/ROS1 mutation, the mOS1 and mOS2 were separately 26.0 months and 6.0 months versus 10.0 months and 1.5 months (P<0.05). The mOS2 of patients with aggressive treatment after PC diagnosis was 6.0 months, significantly better than 1.0 month of patients with best supportive care (P<0.05). The mOS2 of the patients with angiogenesis inhibitors based-treatment after PC diagnosis was 8.5 months, significantly longer than that of patients with other treatments (P<0.05). CONCLUSIONS:Adenocarcinoma and malignant pleural effusion are highly associated with peritoneal carcinomatosis in patients with advanced NSCLC. Aggressive treatment for lung cancer with PC is encouraged when possible. More patients with PC may benefit from the treatment strategies with angiogenesis inhibitors. Further prospective trials are urgently needed.

Project description:Background The histologic classification of lung adenocarcinoma (LUAD) was mainly divided into three pathological subtype groups: the low-grade predominant subtype group (lepidic), the intermediate-grade predominant subtype group (papillary and acinar), and the high-grade predominant subtype group (micropapillary and solid). Previous studies have focused on the prognostic impact of predominant subtypes of lung adenocarcinoma. In this investigation, we investigated the effect of the second predominant subtype on prognosis. Methods The data of LUAD postoperative patients were retrospectively collected. Exclusion criteria included cases in which the pathologic results revealed a single characteristic, the presence of invasive mucinous LUAD, or if the first predominant and the second predominant groups could not be distinguished. Categorical variables were compared with the two-tailed Pearson χ2 test and continuous variables with the Student’s t-test. Follow-up was conducted by telephone and other methods. Independent prognostic factors of the second major subtype were determined by the Kaplan-Meier method and log-rank test. The Cox proportional risk regression model was used to analyze the possible prognostic factors. Results Among 293 patients, the mean age was 61.9 years and 47.1% were male. The results revealed that when the predominant group was the low-grade group, the second predominant groups had no significant influence on overall survival (OS) (P=0.15) but significantly influenced disease free survival (DFS) (P=0.037). Subsequently, when the predominant group was the intermediate-grade group, the second predominant groups significantly influenced OS (P=0.024) but had no significant influence on DFS (P=0.3). Moreover, when the predominant group was the high-grade group, the second predominant groups significantly influenced OS (P=0.033) but had no significant influence on DFS (P=0.31). Conclusions The independent prognostic effect of the second predominant group was not identified for OS and DFS of lung adenocarcinoma. The effects of the second predominant subtype groups on OS and DFS were not evenly distributed among different predominant subtype groups, and the low-grade second predominant subtype exhibited some protective effects on the middle-grade predominant subtypes.
