Arterial chemoembolization was performed three times preoperatively for cancer associated with fistula-in-ano for diminishing the postoperative surgical tissue defect of the perineum. Partial response of the tumor to this treatment was confirmed by computed tomography. A sixty-two-year-old male patient recognized a mass in the perineum one and a half years ago. He had suffered from fistula-in-ano for thirty years. The mass increased its size and formed a tumor in the bilateral buttocks (12 x 9 cm and 9 x 9 cm in diameter). Biopsy specimen showed a moderately differentiated adenocarcinoma. Angiography showed a hypervascular tumor stain. The main feeders to the tumor were the superior rectal artery and bilateral internal iliac artery. Arterial chemoembolization was performed three times through the right and left internal iliac artery with Gelfoam particle. Arterial infusion chemotherapy was added through inferior mesenteric artery and bilateral internal iliac artery with a total 120 mg of adriamycin and 1,500 mg of 5-FU simultaneously. The tumor decreased in size to 44% of the preoperative size by the treatment. A radical operation was performed following the preoperative treatment. Preoperative arterial chemoembolization for cancer associated fistula-in-ano was considered to be helpful for local control.
