Purpose: Inherited genotypes may explain the inferior outcomes of African American (AA) men with prostate cancer. To understand how variation in CYP3A4 correlated with outcomes, a retrospective examination of the CYP3A4*1B genotype was performed on men treated with Radiation Therapy Oncology Group (RTOG) 92-02. Methods and Materials: From 1,514 cases, we evaluated 56 (28.4%) of 197 AA and 54 (4.3%) of 1,274 European American (EA) -patients. All patients received goserelin and flutamide for 2 months before and during RT (STAD-RT) +/- 24 months of goserelin (long-term androgen deprivation plus radiation [LTAD-RT]). Events studied included overall survival and biochemical progression using American Society for Therapeutic Radiology and Oncology consensus guidelines. Results: There were no differences in outcome in patients in with or without CYP3A4 data. There was an association between race and CYP3A4 polymorphisms with 75% of EAs having the Wild Type compared to only 25% of AA men (p <0.0001). There was no association between CYP3A4 classification or race and survival or progression. Conclusions: The samples analyzed support previously reported observations about the distribution of CYP3A4*1B genotype by race, but race was not associated with poorer outcome. However, patient numbers were limited, and selection bias cannot be completely ruled out. (c) 2007 Elsevier Inc.
