Abstract
After 3 mo. of chemotherapy with procarbazine, vincristine, cyclophosphamide, and CCNU [1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea], patients with extensive oat cell carcinoma of the lung were randomly allocated to receive 3000 rads of involved-field irradiation and further chemotherapy or to continue with chemotherapy only. All patients received 3000 rads of prophylactic whole-brain irradiation. The addition of involved-field radiation, as given in this trial, not only failed to improve survival but was unable to alter the pattern of sites of initial relapse. There were no cases of extension to the brain in 31 patients who received prophylactic whole-brain irradiation. This was in contrast to a preceding trial in which 6 cases of brain extension occurred among 19 patients who did not receive prophylactic whole-brain irradiation.
