Upper half body irradiation (UHBI) for extensive small cell carcinoma of the lung.
Upper half body irradiation (UHBI) was given to 41 of 121 patients with extensive small cell carcinoma of the lung. All patients were treated with 6 courses of cyclophosphamide, doxorubicin, and vincristine (CAV). Responding patients also received prophylactic cranial irradiation and local irradiation to prechemotherapy intrathoracic disease. Among the 70% (85/121) of patients who responded to chemotherapy, 41 have received UHBI, given one to two months later. The single fraction midline dose given has been increased in successive patients from 300 to 720 cGy (uncorrected for inhomogeneities). Actual lung doses were higher by 9-22%, (determined in 31 patients by CT scanning and lung density measurements). Adverse effects seen were vomiting, fever, drowsiness, myelosuppression, liver dysfunction and dry mouth. All were transient, and no pneumonitis or treatment deaths occurred. Adverse effect rates were similar at all dose levels. UHBI is well tolerated in patients who have received chemotherapy and merits further study.
