    Abstract:
    We report three cases in which CR was maintained after infusion (WHF) was performed for residual metastatic lesions following resection of hepatic metastases from colorectal cancer. (Case 1) A 55-year-old female with sigmoidal cancer and hepatic metastases, H2 (4 lesions). Right lobectomy and partial resection of the left lobe were performed. On the third month following surgery, CT showed two lesions in the lateral segment of the left lobe, and WHF was then begun. One month after the start of infusion, the lesions calcified and following that, disappeared. Infusion was performed for 12 months and the total amount of 5-FU was 52.8 g. Eight years and nine months following surgery, the patient is currently alive and without recurrence. (Case 2) A 65-year-old male with rectal cancer and hepatic metastases, H3 (6 lesions). Four lesions were removed by hepatic resection; however, 2 deep lesions in S4 and S5 were left unresected. WHF was begun one month following surgery, following which the lesions were undetectable by either CT or US. Infusion was performed for 18 months and the total amount of 5-FU was 81 g. Two years and ten months after surgery an isolated lung metastasis was discovered in the right lung and a thoracoscopic partial resection was performed. Eight years and four months following the original surgery and five years and four months following the lung operation the patient is alive and without recurrence. (Case 3) A 55-year-old male with rectal cancer and subsequently discovered hepatic metastases, H3 (5 lesions). Resection of the lateral segment and a partial resection of the right lobe were performed; however, one deep lesion in S7 was left unresected. WHF was begun on the 10th day following surgery. At about eight months there was a change in shape and shrinkage of the lesion. Infusion was performed for 11 months and the total amount of 5-FU was 48 g. Ten months following surgery, CT showed a new lesion in S7 and a partial resection was performed. Intraoperative US confirmed the disappearance of the previous residual lesion in S7. One year and one month following the original surgery, the patient is alive and without recurrence. From these results, it is suggested that with postoperative WHF it is possible to obtain a complete cure in cases of colorectal cancer with hepatic metastases without the resection of all lesions. (*WHF: 5-FU 1,000 mg/m2/5 hrs/week).
