Standard Surgical Procedure for Primary Lung Cancer

Abstract

Surgical treatment for lung cancer has changed in various ways. It can be said that the history of lung cancersurgery began in 1933 with the pneumonectomy by Graham. The “radical lobectomy” presented by Cahan in1960 was the basic concept of the current surgical procedure. The LCSG821 trial conducted by the Lung CancerStudy Group established lobectomy as the standard procedure for lung cancer. With the development of diagnosticimaging, it became possible to detect early lung cancer showing ground glass opacity. The Noguchi classificationplayed a major role in the detection of curable early-stage lung cancer. The JCOG0201 trial conducted in Japanestablished the definition of noninvasive imaging of cancer, which led to the JCOG0804 trial and JCOG0802 trial.This year, the results of the JCOG0802 trial were announced. The interpretation of this trial will play a very important role in establishing standard treatments in the future.
