Improved survival in hodgkin's disease.

Abstract

All patients below the age of 66 whose Hodgkin's disease was treated at the Massachusetts General Hospital between July 1, 1965 and June 30, 1973 were analyzed. The patients were divided into an early group seen before November 1, 1968 and a later group seen after that date. Survival and survival without recurrence were calculated by the actuarial method of Berkson and Gage, and compared with figures obtained from a historical series seen at this institution between 1948 and 1964. In the most recent period (1969-1973), 87% of patients with all stages of Hodgkin's disease were alive five years after diagnosis, a remarkable improvement over the 65% survival of the 1965-1968 group and the 34% survival of the historical series. The excellent survival of the recent group was a result of improved management of patients with advanced disease (Stages III and IV), most plausibly attributed to better appreciation of the extent of disease by surgical staging and to the shift from total nodal irradiation to combination chemotherapy for initial treatment of these patients. Recurrence after irradiation was extremely uncommon in patients in Stage IA and IIA (lymphangiogram-negative, asymptomatic) subjected to aging laparotomy, while similarly staged and irradiated patients in Stages IB and IIB (lymphangiogram-negative, symptomatic) did much less well. Except for the surgically staged patients in Stages IA and IIA, the continuing high relapse rate indicates that five-year survival, even when relapse-free, is not synonymous with cure, and emphasizes the need for caution in predicting the ultimate cure rate with current therapy.
