Role of Ca125 Monitoring in Post Treatment Epithelial Ovarian Cancer Patients
Abstract: The role of routine CA125 monitoring after therapy in epithelial ovarian CA has been questioned after the results of the MRC OV-05/EORTC 55985 study have been published. However, the role of hormonal agents like Tamoxifen or Letrezole in the setting of asymptomatic rise in CA125 has not been addressed in this study, as the treatment group received second-line chemotherapy. The GOG has looked into the role of Tamoxifen and also …
