Adjuvant pelvic irradiation for cervical cancer in the setting of a transplanted pelvic kidney.

Postoperative radiation therapy is often needed following resection for gynecological cancers. A pelvic kidney, whether ectopic or transplanted, is considered an absolute contraindication for radiation if the organ is left in place. A 45-year-old, immunosuppressed patient with FIGO IB1 cervical adenocarcinoma was treated with intensity-modulated radiation therapy (IMRT) to 45 Gy to the modified whole pelvis with a boost to 59.4 Gy to high-risk areas despite having a transplanted kidney in the right iliac fossa. The irradiation prevented further local failure in the pelvis at 36-month follow-up with no decrement in renal function. Radiation to the modified pelvis using IMRT while avoiding the renal allograft is technically feasible and should be offered to more high-risk patients.
