[Lymph node and peritoneum metastases of bile duct cancer responding to chronochemotherapy--a case report].

A 68-year-old man underwent curative pancreaticoduodenectomy for bile duct cancer. The histological diagnosis was well differentiated, invasive type tubular adenocarcinoma, which was 2 x 2 cm in size and had invaded to the adventitia. Lymph node metastasis was not present. The postoperative course was uneventful, but lymph node and peritoneum metastases were detected 18 months after surgery. Chronochemotherapy of 5-FU (500 mg/body), leucovorin (21 mg/body), mitomycin C (2 mg/body) and cisplatin (80 mg/body) was performed without significant side effects. One course of chronochemotherapy was effective for lymph node and peritoneum metastases. The patient died of peritonitis carcinomatosa 10 months after recurrence.
