title: The clinical value of serum TPS in gynecological malignancies.
abstract: This study included 75 cases; 39 with gynecological cancer of different types, stages, and grades (14 ovarian, 11 endometrial, 9 cervical, and 5 vulvovaginal); 23 patients with benign gynecological diseases and 13 normal healthy controls. Serum TPS was estimated using the ELISA kit supplied by Beki Diagnostic AB, Bromma, Sweden. The results of the present study revealed that serum TPS was significantly elevated in cancer patients followed by those with benign diseases. When the cutoff values were adjusted to 137 and 101 U/L, we obtained sensitivities of 56.4% and 82.1% at specifities of 100% and 85%, respectively. The benign diseases group had false positive rates of 13% and 34.8%, respectively. When considering tumor site, vulvo vaginal cancer showed the highest sensitivity (80%) followed by cervical (66.7%), ovarian (50%), and lastly endometrial cancer (45.5%). Serial measurement of TPS was shown to be of important value in the post-surgical follow-up of cancer patients.
