We studied on the effect of combined use of CR1505 with UFT for the subcutaneously transplanted pancreatic cancer induced by BOP (N-nitrosobis (2-oxopropyl) amine) in the Syrian golden hamsters. The tumor growth in the group treated with both CR1505 and UFT was significantly inhibited compared with that in the group treated with only CR1505 or UFT. Labelling index judged by BrdU immunohistochemistry in the group with the combined use was significantly lower than that in the group with the single use. The differences of the body weights and blood analysis were not obscured in the both groups. Moreover, the concentrations of 5-FU and FT207 in tumors were not different between them. These results suggest that a new therapy of the combined use with CR1505 and UFT for the pancreatic cancer should be effective.
