The patterns of care survey of radiation therapy in localized prostate cancer: Similarities between the practice nationally and in minority-rich areas

Purpose: Over the last two decades, the chance for the cure of localized pr ostate cancer by radiation has been improved by the widespread use of PSA f or early detection and by a number of technical advances in treatment deliv ery. This study was designed to determine whether the stage of presentation and the quality of radiation treatment delivered are comparable between Ca ucasian and minority patients nationally and within minority-rich areas. Methods and Materials: A random survey conducted for the Patterns of Care S tudy in Radiation Oncology of 80 facilities treating patients with radiatio n in the USA. Of these, 67 comprise the "National Survey" and 13 a "Minorit y-Rich" survey (>40% of treated patients are minorities). Nine hundred twen ty-six men with localized prostate cancer were treated in 1994, Five hundre d ninety-five were in the national and 331 in the minority-rich survey. The main outcome measures were the clinical features of Caucasian and minority men at presentation and technical characteristics of the treatment deliver ed to them. Results: African-American men presented with more advanced disease (higher- presenting PSA and T-stage) than Caucasians in both the national and the mi nority-rich surveys. Hispanics also presented with later disease and could be grouped with African-American men rather than Caucasians, Overall the st age and PSA at presentation was earlier than seen in the previous Patterns of Care Study survey of 1989, The quality of treatment delivered has improv ed since 1989, with no distinction seen between those facilities sampled na tionally and those within minority-rich areas. Conclusion: African-American and Hispanic men with prostate cancer present for therapy at a later stage than Caucasian men, but when they do, the trea tment received is of comparable quality.
