手術成績からみた小型進行肺癌の手術適応の検討

This report analyzes the operative indication for the small lesion of advanced lung cancer. The subjects consisted of 25 patients with T1N2 lung cancer, one T1N3, four T1M1 and five small lung cancer lesion with dissemination, which was regarded as the small lesion of advanced lung cancer. The cumulative 5-year survival rate after operation for 25 patients with T1N2 lesion was 30.6%. Of 25 patients, 18 were selected patients who underwent a curative operation with a 5-year survival of 37.0%. In the remaining 7 patients, who underwent a non-curative operation, 5-year survival was 0%. As to mediastinal lymph node involvement, it is possible that metastasis to more than two levels of mediastinal lymph nodes or to the upper mediastinal lymph nodes (#1-3) are poor prognostic factors in T1N2 lesion. Another group except T1N2 could not be the comparative materials because they were much fewer in number. But T4 cases associated with small lung cancer lesion with dissemination and T1M1 cases associated with intrapulmonary metastasis encountered at thoracotomy could be expected to have a long-term survival. We conclude that T1N2 patients with metastasis to within one level of mediastinal lymph node, which will possibly have a curative operation, is a proper operative indication for the small lesion of advanced lung cancer
