title: Thioredoxin 1 as a serum marker for ovarian cancer and its use in combination with CA125 for improving the sensitivity of ovarian cancer diagnoses.
abstract: The serum levels of Trx1 in patients with ovarian cancer were significantly higher than those in normal persons and patients with non-cancer inflammatory diseases. The level of Trx1 increased with the Figo stage. Ovarian cancer patients who were determined to be negative for CA125, were observed to have serum Trx1 levels as high as those of CA125-positive patients. In addition, patients with non-cancer inflammatory diseases had lower plasma Trx1 1 levels than did controls, showing that Trx1 allows clear distinctions between ovarian cancer and these non-cancer diseases. Combinational analysis of CA125 with Trx1 for the detection of ovarian cancer suggests that the diagnostic capacity of CA125 alone for the early detection of ovarian cancer, especially regarding sensitivity, is significantly improved by its combination with Trx1. Taken together, we conclude that serum Trx1 is useful for the early diagnosis of ovarian cancer.
