Introduction: We aimed to investigate the serum prolidase activity, total oxidant status (TOS), total antioxidant capacity (TAC), and total free sulfhydryl (-SH) groups in patients with stage I endometrial cancer.
Methods: Serum prolidase activity, TOS, TAC, and -SH levels were measured in patients with endometrial cancer (n = 23) and controls (n = 25).
Results: Serum prolidase activity and TOS were significantly higher in patients with endometrial cancer than in controls (P = 0.02 and P = 0.02, respectively), whereas TAC and -SH group levels were significantly lower (P = 0.004 and P = 0.001, respectively). 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.
