A prospective analysis of chemotherapy following surgical resection of clinical stage I-II small-cell lung cancer.
Thirty-seven (37) consecutive patients with clinical Stage I (T1-2NO, Mo), and Stage II (T1-2N1 Mo) central small-cell lung cancer (SCLC) underwent complete surgical resection of the primary tumor. Ten patients were subsequently pathologically Stage I, 14 patients were Stage II, and 8 were Stage III (T3;N2). The pathologically Stage I, II, and III patients were then treated with chemotherapy consisting of cyclophosphamide (1 g/m2), doxorubicin (50 mg/m2), and vincristine 2 mg (CAV) every 3 weeks for six courses followed by prophylactic cranial irradiation (2000 cGy in 10 fractions). Median survival in Stage I patients is 162 weeks and calculated 5-year survival is 50%; for Stage II patients, median survival is 86 weeks and calculated 5-year survival is 35%. T3;N2 patients have a median survival of 63 weeks; calculated 5-year survival is 21%. Our data suggest surgery plus adjuvant chemotherapy and cranial irradiation results in long-term survival in early central SCLC. These data support the need for randomized surgical trials in Stage I, II, and III central SCLC.
