[Radiotherapy of inoperable, loco-regional epidermoid carcinoma of the lung. 5-year experience].

Results of chest radiotherapy on 48 patients with inoperable squamous-cell carcinoma are reported; 25 patients had continuous treatment whereas the remaining 23 patients had split-course. Objective remission was obtained in 71% of the cases; mean survival was 11.7 months for the whole series, and 14 months for responders. An advantage in objective remission rate for patients having a dose of 60 Gy or more was found. Split-course resulted in similar survival and objective remission rate but was less toxic than continuous treatment. In 43% of cases the disease progressed only loco-regionally. Radiotherapy was interrupted because of toxicity in 23% of cases and there was only a case of life-threatening toxicity.
