Sociodemographic factors associated with prostatectomy utilization and concordance with the physician data query for prostate cancer (United States)

Objectives: Data from the California Cancer Registry were used to model the effect of race/ethnicity, census-derived socioeconomic status (SES), age, year, and stage at diagnosis on prostatectomy utilization in men diagnosed with prostate cancer from 1990 through 1993. Treatment received was compare d with the National Cancer Institute's Physician Data Query (PDQ) to evalua te concordance. Methods: Odds ratios (OR) and 95% confidence intervals (CI) were estimated to assess the likelihood of (a) receiving a prostatectomy and (b) receiving a treatment in concordance with the PDQ. Non-concordance was defined as a prostatectomy performed on a patient who was either diagnosed with AJCC sta ge III or IV prostate cancer, or was older than 70 years. All other treatme nts were considered compliant with the PDQ. Results: Regardless of the stage at diagnosis, men who were younger and liv ed in a neighborhood with higher income and education levels were the most likely to receive a prostatectomy as opposed to other treatments. Black men were the least likely to be treated with prostatectomy (OR = 0.6, CI = 0.5 -0.6), and the differential was evident within all income levels examined. With respect to the PDQ, black men were 1.4 times more likely to receive co ncordant treatment than white men (OR = 1.4, CI = 1.3-1.5). Conclusions: California black men are receiving less aggressive treatment ( that is more concordant with the PDQ) when diagnosed with prostate cancer.
