[Compliance of oral UFT plus leucovorin adjuvant chemotherapy in patients who underwent curative resection for colorectal cancer].

NSABP C-06 study showed that an oralUFT /Leucovorin(LV)regimen proved to be equivalent to an infusional 5-fluorouracil/LV regimen in an adjuvant setting for colorectalcancer. Thus, the oralregimen has been approved as the treatment of choice in Japan, but compliance of the regimen for Japanese patients has scarcely been reported. We assessed the compliance of oralUFT /LV adjuvant chemotherapy(5 cycles, 25weeks)in 99 consecutive colorectal cancer patients undergoing curative resection. Eighty-two percent(81 of 99)received all scheduled doses of UFT plus LV for five cycles. The mean relative dose intensity was 0. 87. Mean treatment courses given were 4. 5. The treatment was discontinued because of toxicity in 18 of the 99 patients. Nine of 18 received UFT only after the toxicities resolved. The remaining nine patients had no chemotherapy. The toxicity was generally mild. Six patients each had grade 3 diarrhea or anorexia, despite inclusion of overlapping cases. Fifteen of the 99 patients(15%)developed grade 3 toxicities. These results suggest that the compliance of oral UFT/LV treatment was equivalent to that of oral UFT adjuvant treatment for various cancers(80-90%).
