title: [Preoperative chemotherapy for advanced colorectal carcinomas--comparison of histological effect between 5'-DFUR + leucovorin tablet and 5'-DFUR alone].
abstract: The authors analyzed the histological effect of preoperative chemotherapy for 62 advanced colorectal cancer patients using resected specimens. Thirty-one patients in the 5'-DFUR + LV group received 800 mg/day of 5'-DFUR and 30 mg/day of leucovorin for 10-14 days just before the operations. Thirty-one patients in the 5'-DFUR group received 5'-DFUR 800 mg/day during the same period. None of the patients in either group developed any side effects. The results of the histological examination showed the number of Grade 1a and 1b cases in the 5'-DFUR + LV group was 22 (66.7%) and 5 (15.2%), respectively, and in the 5'-DFUR group 21 (65.6%) and 5 (15.6%). In the 5'-DFUR + LV group, 3 lesions showed Grade 2 histological degeneration, while there were no such lesions in the 5'-DFUR group. However, our results did not demonstrate any statistical difference between the two groups (p = 0.25, U test).
