[Successful combination chemotherapy for a case of small cell carcinoma of the rectum with multiple liver metastasis].
A 69-year-old-man with small cell carcinoma of the rectum and multiple liver metastases was admitted in December 1996. Poorly differentiated adenocarcinoma was preoperatively diagnosed in a biopsy specimen from the rectum. Chemolipiodolization using 50 mg DXR and 6 ml lipiodol was performed for the multiple liver metastases. Ten days later, he underwent rectal amputation including lymph node dissection combined with the implantation of reservoir for hepatic arterial infusion chemotherapy. After operation 5-FU (500 mg, days 1-5) and CDDP (10 mg, days 1-5) were injected for 3 weeks through hepatic arterial route. The metastatic lesions in the liver represented a good response to the chemolipiodolization, though the metastatic tumor in the liver S4 region did not disappear on CT scan. The histological diagnosis of the resected rectum revealed small cell carcinoma so we attempted additional chemotherapy according to the regimen for treatment of small cell lung cancer. ETP + CDDP therapy was performed, in which ETP (100 mg, days 1-3) and CDDP (80 mg, day 1) were intraarterially infused. After three courses of this therapy, he achieved a complete response (CR) for the liver metastasis. Two courses of ETP + CDDP therapy were additionally performed in the outpatient department, and treatment is currently continued by oral administration of ETP (75 mg/day). He has been free of the disease for 16 months with few side effects. The combination therapy of chemolipiodolization and hepatic arterial infusion chemotherapy with ETP and CDDP may assure a good prognosis for multiple liver metastases of small cell rectal cancer.
