[A case of metastatic colon cancer to paraaortic lymph nodes and liver treated successfully with oxaliplatin combination chemotherapy].

A 62-year-old female had been operated for sigmoid colon cancer and liver metastasis. We showed our original guideline of adjuvant chemotherapy for colorectal cancer to the patient. She selected UFT/LV 3 months after operation. Six months after operation,follow-up CT showed a paraaortic lymph node growing to 1.8 cm. We used FOLFIRI regimen for 3 series, but the nodule size did not change. Twelve months after operation, a new metastatic lesion measuring 2.0 cm appeared in the liver and the paraaortic nodule grew to 3.0 cm in size. We used FOLFOX 4 regimen, which had decreased the size of liver metastasis after only 2 series. After 6 series, liver metastasis disappeared completely and the paraaortic nodule was reduced to 1.2 cm. Making a detailed guideline of adjuvant chemotherapy at each hospital is helpful not only for doctors to have more clinical discretion but for patients to have better-informed consent.
