There were no differences between surgical stages IA and IB or between stages IB and IC (P = 0.189 and P = 0.161, respectively) with respect to prolidase levels, whereas there was a significant difference between stages IA and IC (P < 0.001).Conclusions: Increased serum prolidase activity and oxidative stress may be associated with endometrial cancer, and increased serum prolidase activity may be related to local invasion of endometrial cancer.
