Racial Differences in CYP3A4 Genotype and Survival Among Men Treated on Radiation Therapy Oncology Group (RTOG) 9202: A Phase III Randomized Trial

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.
