From May 1962 to April 1071, 410 lung resections for primary lung carcinoma have been carried out. One hundred and sixty cases of these were resected more than 5 years ago.
The following results have been obtained from these resections.
1) The 5-year survival is 26.4 per cent of all resected cases, excluding operative deaths, and 54.4 per cent of patients who underwent curative operation.
2) The mortality rate within 30 days of resection is 5.6 per cent in the total series. Operative mortality is mainly related to type of resection (13.0 per cent after pneumonectomy, 2.4 per cent after lobectomy).
3) Concerning about :surgical adjuvant therapy, chemotherapy infusion through the bronchial arteries proved comparatively favourable prognosis in the stage 3 group. Preoperative radiation therapy did not show any merit to the results except for Pancoast type tumor or invaded cases into the chest wall. However, it is possible to make the advanced cases to live longer by effective usage of combined treatment of operation, radiation or chemotherapy.
4) The relationships between histologic grouping and survival rate after pulmonary resection were as follows: spuamous cell carcinoma is 404 per cent, adenocarcinoma is 18.0 per cent, large cell carcinoma is 16.7 per cent, small cell carcinoma is 0 per cent. The best prognosis associated with squamous cell carcinoma is due to the highest chance to receive curative operation. On the other hand, the worst prognosis associated with small cell carcinoma is due to the lowest chance to receive curative operation.
5) It was emphasized that clinical stage and histology of the patient are most important factors bearing on the treatment and the prognosis.
