Pulmonary function tests during adjuvant lung irradiation for osteogenic sarcoma

Six patients received whole-lung irradiation at a dose of 2000 rads/4 weeks (nominal standard dose = 700 Rets) after surgery for primary osteogenic sarcoma. Pulmonary function tests performed before and 6-20 months after pulmonary irradiation failed to demonstrate any pulmonary function impairment in any of the patients studied.
