title: [A case of resected small-sized (4 mm in diameter) lung cancer and its way of surgical treatment].
abstract: We report a case of resected lung cancer which was 4 mm in diameter. Pathological diagnosis couldn't be made preoperatively by fiberoptic bronchoscopy. We examined the patient's chest CT carefully and determined the presence or absence of such findings that might indicate malignancy (spicula formation, involvement of pulmonary vasculature, irregularity of tumor edge, pleural indentation, and notching) or benignity (central or diffuse calcification, sattelite lesions). When a lesion shows more than two of five findings listed above that indicate malignancy, and when the diagnosis of lung cancer is agreed upon by a team consists of a radiologist, a physician and a surgeon, we would tell the patient and his/her family that the lesion is most likely a lung cancer, and recommend surgical treatment. Sometimes small-sized lung cancer isn't a early lung cancer so recommend curative standard operation if patient's condition is good.
