This prospective study investigated the presence of pelvic sentinel lymph node (SLN) metastasis in women with peritoneal endometriosis, a condition where endometriosis implants are found on the lining of the pelvic cavity.

This prospective study investigated the presence of endometriosis in pelvic sentinel lymph nodes among women with histologically confirmed peritoneal disease. Researchers removed sentinel lymph nodes following blue dye marking and analyzed them using immunohistochemical staining for estrogen receptor, progesterone receptor, cytokeratin, and CD-10 markers. The results indicated that while frank endometriotic lesions were found in only two of nineteen patients, disseminated stromal cells characteristic of endometriosis were detected in sixteen participants. Consequently, the authors concluded that lymphogenous spread occurs frequently and may serve as a potential prognostic marker for the condition. This paper is centrally about endometriosis — specifically examining the lymphatic dissemination of endometrial-like cells to sentinel lymph nodes.

Abstract

Endometriose ist eine benigne Erkrankung. Ob bei Frauen mit peritonealer Endometriose ein Befall pelviner Sentinellymphknoten (SLN) vorkommt, ist unbekannt.

Ob bei Frauen mit peritonealer Endometriose ein Befall pelviner Sentinellymphknoten (SLN) vorkommt, ist unbekannt. Methode: Prospektive Serie mit SLN-Entfernung nach Blaumarkierung bei Frauen mit histologisch gesicherter Endometriose. Immunhistochemische Färbung für ER, PR, CK, CD-10. Ergebnisse: 37 SLN wurden bei 19 Frauen entfernt. Endometrioseherde (ER+, PR+, CK+, CD-10+) wurden in 2/19, disseminierte ER+, PR+, CK+, CD-10- Zellen in 16/19 Frauen gefunden. Schlussfolgerung: Frauen mit peritonealer Endometriose weisen einen pelvinen SLN-Befall in etwa 10% der Fälle auf. Disseminierte Endometriosezellen stromaler Herkunft finden sich in einem Großteil betroffener Frauen. Die lymphogene Aussaat ist ein potenzieller prognostischer und prädiktiver Marker der Endometriose.
