The effects of thymidine phosphorylase inhibitor (TPI) on tumor weight. After the tumor size reached about 50–150 mm³, TPI was administered i.p. for 22 days at the indicated amounts. Statistical significance was determined using multiple regression analysis, adjusting for tumor type and observation period (mean ± standard error of the mean; n = 6). Data were adapted from Matsushita et al. (1999; with permission).^{( 56 )}
