Background: Intrahepatic continuous infusion FUDR induces a 50% response rate in patients with hepatic metastases from colorectal cancer. Lower rates have been observed in pretreated patients. The combination of floxuridine plus leucovorin has obtained over 70% responses, with high hepatic toxicity. The use of dexamethasone can decrease hepatic toxicity.

Methods: On such premises, since July 1993 we have treated 39 patients affected by unresectable hepatic metastases from colon carcinoma (26 patients) and rectal carcinoma (13 patients) with the combination continuous infusion of floxuridine (0.20 mg/kg per day) + leucovorin (7.5 mg/m(2)/day) + dexamethasone (20 mg on days 1 to 14) and bolus mitomycin C (10 mg/m(2) on day 1) via the hepatic artery.

Results: Of 39 patients 37 were assessable for response (2 patients were not assessable because they stopped chemotherapy for occlusion of the catheter after the first cycle).

Conclusions: The treatment we used showed an elevated activity in liver metastases from colorectal cancer even in patients pretreated and resistant to systemic chemotherapy, although toxicity grade 3-4 diarrhea occurred in approximately 40% of the patients.

Abstract

Background: Intrahepatic continuous infusion FUDR induces a 50% response rate in patients with hepatic metastases from colorectal cancer. Lower rates have been observed in pretreated patients. The combination of floxuridine plus leucovorin has obtained over 70% responses, with high hepatic toxicity. The use of dexamethasone can decrease hepatic toxicity. A randomized study reported an increase in response rate and a decrease in hepatic toxicity in a group of patients treated with floxuridine plus dexamethasone compared to a group receiving only floxuridine, Moreover, the combination of mitomycin C, carmustine and floxuridine is also effective in pretreated patients. Methods: On such premises, since July 1993 we have treated 39 patients affected by unresectable hepatic metastases from colon carcinoma (26 patients) and rectal carcinoma (13 patients) with the combination continuous infusion of floxuridine (0.20 mg/kg per day) + leucovorin (7.5 mg/m(2)/day) + dexamethasone (20 mg on days 1 to 14) and bolus mitomycin C (10 mg/m(2) on day 1) via the hepatic artery. Cycles were administered every four weeks. There were as 28 males and II females, with a median age of 64 years (range, 39-75) and a median PS = 0, Twenty-two patients were pretreated with systemic chemotherapy including 5-fluorouracil plus leucovorin, Total number of cycles was 189, with a median of 6 cycles per patient (range, 1-12). Results: Of 39 patients 37 were assessable for response (2 patients were not assessable because they stopped chemotherapy for occlusion of the catheter after the first cycle). There were 3 complete responses (1 in a naive patient and 2 in pretreated patients), 16 partial responses (11 in pretreated patients and 5 in chemonaive patients), 4 minor responses, 4 stable disease and 10 progressive disease.
