The National Cancer Data Base report on Hodgkin's disease for 1985-1989 and 1990-1994.

Abstract

A national survey of the management of Hodgkin's disease patients based on cases in the National Cancer Data Base (NCDB) provides a basis for evaluating the results of educational and therapeutic programs. These patients are believed to have been drawn from all nationalities, native and migrant, and were reported by hospital cancer registries throughout the United States, including large and small community hospitals, university and other teaching hospitals, military and Veterans Administration (VA) hospitals, and National Cancer Institute (NCI)-Designated Centers. Data submitted voluntarily to the NCDB were used to determine trends in patterns of patient care across time. For the period 1985-1994, data from 35,033 patients with newly diagnosed Hodgkin's disease were analyzed and separated into two time periods, 1985-1989 and 1990-1994. Data were analyzed with respect to age, race, histology, stage, treatment, and survival. The majority of patients (83.6%) were white, the age group with the highest incidence was 20-29 years, and nodular sclerosis was the most common histologic type. Staging was reported as a combination of clinical and pathologic stage ("combined stage"). The number of cases of reported stage increased from 51.7% for the years 1985-1989 to 75.7% for the years 1990-1994. Radiation therapy was used primarily to treat patients in Stages I and II, although the overall use of radiotherapy declined by 10% in the later period. The overall observed 5-year survival rate was 83.2%, and the disease specific observed survival rate was 84.9%. Stage for stage, survival was better for younger patients and poorer for older patients. The survey reflects the actual management of Hodgkin's patients disease. The reported cases for 1994 represent 60.6% of the estimated occurrences for that year in the U.S. There has been a significant improvement in the frequency of use of the staging system. A continuing increase in survival for patients with Hodgkin's disease is occurring. This method of studying disease management provides a measure of educational efforts and guides to developmental research.
