    Abstract:
    BACKGROUND: Patterns of care for prostate cancer patients in the United States have changed as early detection has improved. The National Cancer Data Base of the American College of Surgeons Commission on Cancer provides information about the treatment of patients in all age, race, and regional groups from institutions that represent cancer care at the community level as well as in medical centers. METHODS: Data on 251,416 prostate cancer patients diagnosed between 1992 and 1994 were studied. Patient and disease characteristics, including age, race, the geographic region from which a case was reported, American Joint Committee on Cancer stage, and tumor grade were related to the primary pattern of treatment. Stage-standardized comparisons were made among different age groups, race groups, and regional groups. RESULTS: Stage and tumor grade varied little across age, race, and regional classifications. African American patients were more likely than white patients to have Stage IV prostate cancer at the time of diagnosis. Men older than 75 years had greater proportions than younger men of both the earliest and the most advanced stages of cancer. Overall, 24.6% of patients received no cancer-directed therapy, 11.6% were treated with hormones or endocrine surgery, 28.6% received radiation therapy, 28.3% underwent radical prostatectomy, and 6.9% were treated by other modalities or combinations of modalities. Treatment patterns varied markedly by age. The selection of radical prostatectomy relative to no treatment and radiation therapy varied by race and region. CONCLUSIONS: The results of this study showed that prostate cancer treatment varies by patient age, race, and geographic region. The reasons for some of these variations are not well understood and deserve further investigation.
