title: [Surgical analysis for small cell lung cancer of the lung].
abstract: Clinical features of small cell lung cancer were studied in 15 cases. The overall 5-year survival rate of the patients with limited small cell lung cancer was 11.4%. Surgery played substantial role for long-term survival in limited SCLC. The 4-year-survival rate of the patients in stage I was 50%, and that of those in stage II and IIIA was 50% and 37.5%, respectively. In the two survivors over four years in stage IIIA, all tumor was categorized as pT3 disease. The 4-year-survival rate of the patients treated with PE was 100%, and that of those treated with another chemotherapy was 10%, and that difference is statistically significant (p < 0.05). There was no significant difference in prognosis of patients in any other factors such as location (central or peripheral), histological subtype, curability or R number, pT factor, pN factor, p stage or with or without thoracic irradiation. Surgical resection for limited SCLC should be recommended in patients with stage I, II and T3N0M0 or T3N1M0 disease. For the patients in stage IIIA, particularly in N2M0 disease, who showed partial response or no change after chemotherapy, surgery should be considered because those patients might have nonsmall cell carcinoma components.
