One hundred seventy-six patients with pathologically staged IA and IIA Hodgkin disease (HD) treated with irradiation alone were evaluated for long-term survival and freedom from relapse (FFR). Most of the patients received treatment to mantle and paraaortic fields; chemotherapy was not given except as salvage therapy. For pathologically staged IA disease, the 5-, 10-, and 15-year survival rates were 94%; the corresponding FFR rates were 96%, 93%, and 93%. For pathologically staged IIA disease, respective survival rates were 93%, 89%, and 80%, with FFR rates of 86%, 84%, and 84%. Twenty-one patients (12%) had relapse of HD; salvage therapy was successful in 11 of these patients. Pelvic recurrence was uncommon (three of 176 cases [2%]). No patient developed leukemia, and only two patients developed second malignancies (lung cancer in both cases). The authors conclude that radiation therapy is effective in treatment of early-stage HD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
