Abstract
Forty-seven patients with unresectable non small cell lung carcinoma, 15 stage IIIA, 31 stage IIIB, 1 stage IV (cervical lymphadenopathy) were treated with a combination of three courses of chemotherapy and hypofractionated irradiation followed after 3 weeks by split course radiotherapy. Each course was repeated every 3 weeks with the following sequence: Cisplatinum (CDDP) (20 mg/m 2) was given in a 20-min infusion, followed by a 2-h infusion of 5-fluorouracil (5-FU) (400 mg/m 2) on days 1, 2, 5 and 6. Radiation with a dose of 3 Gy on the target volume was given on days 3 and 4 - in one fraction for the former 27 patients, in 2 fractions of 1.5 Gy for the latter 20 patients with a 6-h interval — after a 2-h infusion of 5-FU (400 mg/m 2). The results remain disappointing: the objective response rate was 53%, the median survival was 10 months for the series, and the one-year survival 47%. The median survival was 14 months for IIIA, 10 months for IIIB and IV. Regarding the therapeutic regimen there seems to be less morbidity with 2 fractions per day for which the median survival is nearly the same at 10 months (1 fraction/day) versus 12 months (2 fractions/day).
