using the src assay with 7 colorectal cancer specimens , the relative variation of tumor size , which was calculated by delta ts/ts0 = ( ts6-ts0 ) /ts0 x 100 ( % ) , decreased to -12.6 +/- 10.1 % for 5-fu , -14.9 +/- 12.4 % for tegafur and -23.9 +/- 14.2 % for hcfu , and the inhibition of tumor growth following exposure to hcfu was evident .
