BACKGROUND: The National @entity5 Data Base (NCDB) has reported on many @entity5 occurring in @entity1 and @entity1 in the U. S. from >1400 contributing hospitals. The current report on @entity1893 ( @entity1893 ) is a companion to an upcoming @entity1 Care Evaluation study of this relatively common and serious @entity5 . METHODS: This report is comprised of all @entity1893 cases submitted to the NCDB divided into two diagnostic-year groups: 1985-1988 and 1990-1993. Variables routinely collected by hospital @entity5 registries have been analyzed to report on patterns of diagnosis and treatment. RESULTS: High grade @entity1893 cases were more likely to be Stage IV (40.8%) than were low or intermediate grade cases (34.8% and 32.5%, respectively). @entity1 with @entity1893 arising from lymph node sites tended to present with more @entity1442 (55.8% with Stages III and @entity66 ), whereas @entity1 with @entity1893 arising from extranodal sites and non-lymph node nodal sites presented at an earlier stage (64.7% and 74.0%, respectively, with Stage I or @entity34 ). Approximately 67% of all @entity1 underwent chemotherapy, whereas only 25% underwent surgery or radiation. By histology, 5-year survival was 68.8% for low grade disease, 51.9% for intermediate grade disease, and 45.8% for high grade disease; by stage, survival rates ranged from 73.5% for Stage I to 42.9% for Stage @entity66 . CONCLUSIONS: To the authors' knowledge, the 91,306 cases in this study represent the largest contemporary sample of @entity1893 @entity1 . The material reported here may serve as a reference with which to compare local patterns with national data. The Working Formulation's ability to stratify @entity1 ' survival rates confirms its utility for @entity1893 . Stage according to the American Joint Committee on @entity5 also was accurate in predicting survival.
