Abstract
BACKGROUND: With the popularization of high-resolution computed tomography (HRCT), there is a rising trend of the detection of multiple primary lung cancers (MPLC). Adenocarcinomas is the major pathological type of MPLC. At present, reports on MPLC are relatively common, but few study focused on synchronous multiple primary lung adenocarcinomas (SMPLA). We carried out this study in an attempt to enhance our understanding about SMPLA.Entities:
