Preoperative Examination to Detect Distant Metastasis Is Not Advocated for Asymptomatic Patients with Stages 1 and 2 Non-Small Cell Lung Cancer: Preoperative Examination for Lung Cancer

摘要: The purpose of the present study was to determine whether all patients with non-small cell lung cancer, clinically defined as stage 1 or 2, should have examinations presence distant metastatic (Ml) disease. survival rates who underwent and those did not were compared. In groups, had in no way positively affected survival. 33 whom recurrence occurred within 12 months curative operation, then evaluated establish relationship between recurrent site preoperative examination: negative scans on examination failed predict low incidence early recurrence. Those data suggest that routine use radionuclide CT is benefit asymptomatic local,
