Serous tubal intraepithelial carcinoma (STIC) – clinical impact and management

ABSTRACT Introduction: Serous tubal intraepithelial carcinoma (STIC) is most likely precursor lesion of the most part of high-grade serous pelvis carcinomas, carcinosarcoma and undifferentiated carcinoma with incidence of 0.6% to 7% in BRCA carriers or women with strong family history of breast or ovarian carcinoma. STIC is a pathomorphologically and immunohistochemically detectable lesion which biological significance and clinical relevance is unknown. Areas covered: We investigate methods of STIC diagnostics and we present an overview of recent studies and available knowledge on surgical management, adjuvant chemotherapy and subsequent follow-up procedure in women with an isolated STIC. Expert commentary: Patients found to have an incidental STIC lesion should be referred for screening of BRCA1/2 mutation. In absence of an invasive disease, follow-up of patient remains a reasonable choice. A rational scheme should include check-ups every 6 months consisting of gynecological examinations, CA 125 and/or HE4 and pelvic ultrasound examination by an expert sonographer.
