Endometrial cancer (EC) is the most common gynecologic malignancy in developed countries. Although most patients are diagnosed at early stages, 15-20% will relapse despite local treatment. Presently, there are no reliable markers to identify patients with worse outcomes who may benefit from adjuvant treatments, such as chemotherapy, and liquid biopsies may be of use in this setting.

Although the majority of endometrial cancers are diagnosed at early stages and the 5-year overall survival is around 80%, early detection of these tumors is crucial to improve the survival of patients given that the advanced tumors are associated with a poor outcome. Furthermore, correct assessment of the pre-clinical diagnosis is decisive to guide the surgical treatment and management of the patient.

Article Synopsis
  • Determining the origin of primary tumors in ovarian and peritoneal metastases can be challenging, leading to a study involving 25 metastatic tumors to the ovary and 7 cases of peritoneal carcinomatosis suspected to have gynecologic origins.
  • The Tissue of Origin-Frozen test, a gene expression-based method, was able to accurately identify the site of origin in more cases compared to traditional immunohistochemical staining techniques.
  • The combination of the Tissue of Origin-Frozen test and immunohistochemistry successfully identified the correct tumor origin in 19 out of 22 cases, highlighting its potential usefulness in complicated diagnoses.
