Regional administration of irinotecan in combination with 5-fluorouracil and leucovorin in patients with colorectal cancer liver metastases--a pilot experience.

Regional chemotherapy represents an effective approach for the control of isolated liver metastases of colorectal cancer. Fluoropyrimidines have been the basis of systemic and regional chemotherapy of this disease for several decades, but recent studies have demonstrated that the addition of irinotecan (CPT-11) ameliorates the results of systemic treatment.
Fifteen patients with isolated liver metastases of colorectal carcinoma were treated with regional administration of CPT-11 in combination with 5-fluorouracil/folinic acid (5-FU/FA). CPT-11 (100-200 mg, mean: 93 +/- 25, range: 51-125 mg/m2) was administered weekly in combination with 5-FU (1000-2000 mg, 857 +/- 182, range: 538-1301 mg/m2) and FA (100-350 mg). Peripheral blood leukocyte phenotype was examined during the treatment in selected patients.
One patient achieved complete response, 4 patients had partial response, 7 patients had stable disease, 1 patient progressed and 2 patients were not evaluable. The response rate was 38% in evaluable patients, and a more than 50% decrease in serum carcinoembryonic antigen levels was observed in 12 out of 14 patients. The treatment was generally well tolerated. All patients, except one, are currently alive at mean follow-up of 11 +/- 6 (median: 10, range: 5-24) months. The therapy is still being continued in 8 patients.
Weekly CPT-11/5-FU/FA is highly effective in the treatment of patients with metastatic colorectal cancer limited to the liver, even after failure of previous 5-FU/FA. The present regimen should be tested as a first line treatment in phase III trial.
