U.S. Asians' Prostate Cancer Survival Similar to Whites
Traditional prognostic factors are not accurate predictors of survival in these patients
WEDNESDAY, Aug. 15 (HealthDay News) -- Asian American men with prostate cancer appear to have survival comparable to white Americans, despite prognostic factors that predict worsened survival, according to study findings published online Aug. 13 in Cancer.
Anthony Robbins, M.D., Ph.D., of the California Cancer Registry in Sacramento, and colleagues analyzed data from 116,916 California males with prostate cancer including whites and the six most common Asian subgroups in America (Chinese, Filipino, Japanese, Korean, South Asian and Vietnamese).
Traditional prognostic factors did not accurately predict Asian men's survival. Each Asian subgroup had worse prognostic profiles that put them at a survival disadvantage compared to whites. However, in unadjusted analyses, Japanese men had improved survival compared to whites, and Chinese, Filipino, Korean and Vietnamese had statistically equal survival. Only South Asians had worse survival. After adjustment for prognostic factors, all groups had equal or improved survival compared to whites.
"These results argue that traditional prognostic factors for survival from prostate cancer -- stage, grade, treatment, age, year of diagnosis, and socioeconomic status -- do not explain why the majority of Asian men have better survival compared with whites, but they do explain the poorer survival of South Asian men compared with whites," the authors conclude.
