OBJECTIVE: The effectiveness of capecitabine, an oral fluoropyrimidine carbamate, is well documented in previously untreated metastatic colorectal cancer patients (overall response rate: 25%). However, its efficacy in patients with metastatic colorectal cancer refractory to 5-fluorouracil/leucovorin (5-FU/LV) has not been determined. This study was performed to evaluate the efficacy and to identify the side-effects of capecitabine in patients with metastatic colorectal cancer showing progression despite 5-FU/LV-based combination chemotherapy.
METHODS: Fifty-one metastatic colorectal cancer patients who showed progressive disease in 5-FU/LV-containing regimens (median: two regimes) were treated with capecitabine 1,250 mg/m(2) twice daily (days 1-14 repeated every 3 weeks).
RESULTS: Only one partial response was observed (response rate: 2%). Twenty-seven patients (53%) showed stable disease after two cycles. The median time to disease progression of either a partial response or stable disease was 3.4 months. Hand-foot syndrome wasthe main toxicity of capecitabine and occurred in 35% of cases (grade 3 or 4 in 6%). The median number of cycles administered was two and the relative dose intensity of capecitabine was 80%.
CONCLUSION: The response rate to capecitabine was low in metastatic colorectal cancers that were refractory to 5-FU/LV-containing chemotherapy. However, disease stabilization was seen in a significant number of patients.
