The growth and maturation of the National Cancer Data Base

BACKGROUND: The National Cancer Data Base (NCDB), a joint project of the Commission on Cancer of the American College of Surgeons and the American Cancer Society, is a cancer management and outcomes data base for health care organizations. It provides a comparative summary of patient care that is used by communities and participating hospitals for self-assessment. The most current (1994) data are described here. METHODS: Six calls for data have yielded a total of 4,580,000 cases for the years 1985-1994. A total of 1735 hospital cancer registries have each participated in at least one of the calls for data. RESULTS: Summing the last year's report from each of the 1227 hospitals that participated in 1994, the cases represent the equivalent of 57% of the estimated 1994 U.S. cancer cases. These data were received from all six regions of the country, including all 50 states. Ninety-seven percent of patients received all or part of their treatment at the reporting hospital. The four most common cancers are carcinomas of the breast (15.7%), lung (14.3%), prostate (13.1%), and colon (7.7%), and collectively they comprise a majority of new cases. CONCLUSIONS: The NCDB is a cancer management and outcomes data base for health care organizations that currently provides data on 57% of the estimated new cases in the U.S. Past data have been used extensively to assess patterns of care and outcomes.
