title: [A case of advanced colon cancer with metastases to both the Virchow's and the paraaortic lymph nodes that achieved complete long-term response with levofolinate.5-FU therapy].
abstract: A 48-year-old woman presented with a tumor in the supra-clavicular fossa. Under a diagnosis of advanced ileocecal colon cancer with metastases to Virchow's and the paraaortic lymph nodes, ileocecal resection was performed. After surgery, the patient was given 5-FU infused continuously at 500 mg/body per day, and levofolinate was dripped intravenously at 100 mg/body over 2 hours for 5 successive days per week. Two cycles were repeated each week. She was then intravenously given weekly modulation chemotherapy consisting of 125 mg/body levofolinate and 500 mg/body of 5-FU for about 5 months on an outpatient basis. Furthermore, the same administration schedule was continued bi-weekly for 1 year and 4 months. As a result, the enlarged paraaortic lymph nodes had completely disappeared by 5 months after administration of levofolinate.5-FU. The Virchow's lymph node metastasis has not been palpable for 11 months. Throughout the period of treatment, there were no severe side effects and as of this writing, no sign of recurrence for 3 years after surgery. A high quality of life has been maintained. In conclusion, this case seems significant from the viewpoint of the complete long-term response to a moderate dose of levofolinate.5-FU therapy and the long duration of administration, which was tolerable with few side effects. Moreover, we identified the presence of TS and DPD using immunohistochemical staining techniques, when both primary tumor and regional lymph nodes were all negative for the stain test. It was suggested that this cancer especially would responded to 5-FU chemotherapy.
