The survival rate of women with colorectal carcinoma is higher than that of men. This is true when censored survival rates are compared (P = 0.0008) as well as when relative survival rates are utilized to compensate for the increased life expectancy of females. Women never pregnant (n = 56) or women with no children (n = 66) showed survival rates similar to men, but significantly different to women with one or more children. The actual number of children, however, did not correlate with survival rates.
结直肠癌女性患者的生存率高于男性。无论是比较删失生存率（P = 0.0008），还是使用相对生存率来补偿女性预期寿命的增加，情况都是如此。从未怀孕的女性（n = 56）或没有子女的女性（n = 66）的生存率与男性相似，但与有一个或多个子女的女性有显著差异。然而，子女的实际数量与生存率并无关联。
