Abstract
BACKGROUND: The different expression of tumor-stroma ratio (TSR) have been proved to be a new and reliable independent prognostic factor in some solid tumors.The aim of the study is to test the different expression of TSR and its prognostic significance in non-small cell lung cancer (NSCLC).Entities:

273例NSCLC患者Kaplan-Meier生存分析。结果显示间质稀少组患者中位生存时间为1, 169 d, 间质丰富组的患者中位生存时间为808 d。间质丰富组的患者OS明显低于间质稀少组的患者(P=0.014)。
Kaplan-Meier survival analysis of 73 cases with NSCLC.Results show that the median survival time in the stroma-poor group was 1, 169 d, and 808 d in the stroma-rich group.OS days of patients in stroma-rich group were significantly lower than the stroma-poor group (P=0.014).OS:Overall survival.
