RESULTS OF A CHANGING TREATMENT PHILOSOPHY FOR CHILDREN WITH STAGE-1 HODGKINS-DISEASE - A 35-YEAR EXPERIENCE

Over the last four decades, significant changes have occurred in the management of childhood stage I Hodgkin's disease. Between 1949 and 1984, 50 children, ages 4 to 16 years, were treated for stage I Hodgkin's disease at The University of Texas M. D. Anderson Cancer Center. Nineteen children had clinically staged (CS) disease. Thirty-one patients were pathologically staged (PS). Thirty-four children were treated with radiotherapy only, 12 were treated with both radiotherapy and chemotherapy, and 3 patients were treated with combination chemotherapy alone. All patients were followed from 32 to 311 months (median 170 months). Five-, 10-, and 15-year actuarial survival rates for all patients were 94, 89, and 84%, respectively. The corresponding freedom from relapse (FFR) rates were 76, 69, and 69% respectively. The 10-year actuarial survival and FFR rates for CS patients were 79 and 42%. The corresponding rates for PS patients were 97 and 86%. In patients with PSI disease, actuarial 10-year FFR rates of 100% were obtained either with regional radiotherapy alone or with combination chemotherapy and involved field radiotherapy. The following delayed adverse effects of treatment were observed: growth abnormalities in 17, aspermia in 3, thyroid abnormalities in 11 (two carcinomas), and second malignancies beyond the radiotherapy fields in 2. We conclude with a recommendation of combined chemotherapy and involved field radiation for children who have not fulfilled their growth potential, to achieve high cure rates, while minimizing morbidity.
