Two patients were diagnosed with large rectal tumors and localized prostate cancer. The prostate-specific antigen level at diagnosis was 7.9 ng/mL and 9.0 ng/mL in the 2 patients. Knowledge of the presence of both tumors and their close proximity allowed creation of a modified three-dimensional conformal radiotherapy plan to treat both tumors. The patients had no evidence of rectal tumor recurrence and their prostate-specific antigen level was 0.5 ng/mL and 0.7 ng/mL at 1 and 2 years after therapy, respectively. We conclude that efficient, effective pelvic irradiation can be designed for synchronous rectal and prostate malignancies.
