Abstract
BACKGROUND: It has been known that the volume doubling time (VDT) of different lung nodule types is different. At present, there is still a lack of studies about the volume doubling time of lung cancer with different pathological types. The purpose of the study is to explore the factors influencing the progression of the early-stage adenocarcinoma, and provide some reference for the follow-up strategy of lung nodules by retrospective analysis of the image data of 143 early-stage adenocarcinoma.Entities:
