Prognostic significance of the 8th edition of the TNM classification for patients with extensive disease small cell lung cancer.

ABSTRACT:

Background

Small cell lung cancer (SCLC) is typically categorized according to disease extent as limited or extensive, and utility of the 8th TNM classification, recommended for lung cancer staging, which demonstrates a strong association with non-small-cell lung cancer (NSCLC) management, remains unclear.

Methods

This retrospective study included 277 consecutive SCLC patients treated at a single institution between 2008 and 2016.

Results

According to the currently used two-stage system, 186 (65.7%) of the patients were classified as having extensive disease (ED)-SCLC. Among the ED-SCLC patients, ten (5.3%), 38 (20.4%), 32 (17.2%), and 106 (57.0%) were categorized into stages M0, M1a, M1b, and M1c, respectively, according to the 8th TNM classification.
