[Intentional limited operation for minute peripheral adenocarcinoma of the lung].
The purpose of this report is to evaluate the limited operation for peripheral minute adenocarcinoma of the lung. Firstly, 44 cases (47 lesions) of surgically resected minute peripheral lung adenocarcinoma, 10 mm or less in diameter, were reviewed using Noguchi's classification, and the correlation between high resolution CT (HRCT) images and the clinicopathological features was examined retrospectively. All type A and B adenocarcinomas (n = 14) had no recurrence and all cases were the air containing type by HRCT. Lymph node metastasis and lymphatic/vascular involvement were detected with type C, D, E, F and 3 cases among them were died for recurrence. Based on those results, from April 2000, intentional limited operation was prospectively performed for 14 patients (16 lesions) with peripheral nodule showing ground-glass opacity on HRCT. The pathological findings were type A (n = 9), type B (n = 5), and atypical adenomatous hyperplasia was one case (If the findings were confirmed type C, D, E, F by permanent section diagnosis, VATS lobectomy will be performed). We recommend limited operation should be performed in only type A or B adenocarcinoma and permanent section diagnosis is necessary to determine whether or not.
