ABSTRACT
Resumen: ANTECEDENTES: El carcinoma intraepitelial tubárico seroso es una lesión precursora del carcinoma invasivo de las trompas de Falopio que con frecuencia se diagnostica en el contexto de una salpingooforectomía bilateral profiláctica por patología ginecológica benigna. CASO CLÍNICO: Paciente nulípara, de 51 años, con cuadro clínico de dolor abdominal y elevación de marcadores tumorales CA-125 y CA-19.9, diagnosticada con útero polimiomatoso y sospecha de endometrioma en el ovario derecho. Después de la histerectomía subtotal con anexectomía bilateral, el estudio histológico de la pieza tubárica extirpada reportó focos microscópicos de carcinoma intraepitelial tubárico seroso, sin signos de invasión estromal. Por los hallazgos se solicitaron pruebas de imagen mamarias y el estudio genético de mutación BRCA 1 y 2. CONCLUSIÓN: La salpingooforectomía bilateral profiláctica es un procedimiento que reduce el riesgo de carcinomas peritoneales, tubáricos y serosos de ovario. Las pacientes con carcinoma intraepitelial tubárico seroso deben tener seguimiento basado en controles ecográficos, pruebas de imagen mamarias, determinación de marcadores tumorales y estudios genéticos, debido a su asociación con mutaciones en los genes BRCA 1 y 2.
Abstract: BACKGROUND: Serous tubal intraepithelial carcinoma (STIC) is a precursor lesion of invasive high-grade tubal and serous carcinoma of the ovary, frequently diagnosed in the context of prophylactic bilateral salpingoophorectomy for benign gynecological pathology. The objective of this work is to carry out a literature review on the most relevant aspects of the follow-up of this injury, after its incidental diagnosis in gynecological surgery. CLINICAL CASE: A 51-year-old nulliparous patient who, in the context of a clinical situation of abdominal pain with elevation of tumor markers CA125 and CA19.9, was diagnosed with polymomatous uterus and suspected endometrioma in the right ovary. After a subtotal hysterectomy with bilateral adnexectomy, the histological study of the excised tubal specimen found microscopic foci of STIC without signs of stromal invasion. Given this finding, breast imaging tests and a genetic study of the BRCA 1/2 mutation was requested. CONCLUSION: Prophylactic bilateral salpingoophorectomy in gynecological surgery is a procedure that can reduce the risk of developing peritoneal, tubal, and serous ovarian carcinomas. Patients diagnosed with STIC should be subsidiaries of follow-up based on ultrasound controls, mammary imaging tests, tumor markers, and genetic studies, due to their association in many cases with mutations in the BRCA 1/2 genes. It is necessary to establish a series of standardized clinical protocols for the management of patients with STIC and to continue advancing our understanding of this pathology and its subsequent evolution to high-grade serous carcinoma.
