[Results of the radiotherapy of Hodgkin's disease (Analysis of cases at Osaka University Hospital)].

A total of 32 patients of Hodgkin's disease treated mainly by radiotherapy at the Department of Radiology, Osaka University Hospital from 1971 through 1985 were analyzed. Five- and ten-year survival rates for all patients were 91%, 78%; Clinical Stage I (15 patients): 93%, 83%; Stage II (8 pts.): 100%, 100%; Stage III (9 pts.): 78%, 52%, respectively, and 5- and 10-year relapse-free rates for all patients: 72%, 62%; St. I 87%, 76%; St. II: 63%, 63%; St. III: 56%, 42%, respectively. Patients with tumor originated in the upper neck consisted of 7 patients (47%) in Stage I and no relapse was observed outside the irradiated field. However, 2 recurrences (1 within RT field, and another Stage III at margin of the field) were observed around the upper neck in patients treated with only the mantle field encompassing the upper neck area. Treatment portal should be considered to cover Waldeyer's ring and skull base with lateral portals.
