Predictors Of Limph Node Metastasis In Endometrial Cancer

Abstract

Introduction: Endometrial cancer is the most common gynecologic malignancy in developed countries. The adequate surgical staging proposed by FIGO (International Federation for Gynaecology and Obstetrics) advocates lymphadenectomy; however, it does not establish the indications, the type and the extent of lymphadenectomy, thus generating multiple controversies. 

Methods: Retrospective, analytical study of patients treated surgically for endometrial adenocarcinoma in the Oncological Institute ”Prof. Dr. Ion Chiricuţă” Cluj-Napoca (IOCN) between January 2008 and December 2012 – 709 cases eligible for the study. 

Results: 206 pelvic and/or paraaortic lymphadenectomies were performed, the average number of excised lymph nodes being 15.6. Overall in 4.4% of patients the lymph nodes were affected by metastases. The presence of each risk factor analysed was statistically significantly associated with lymph node metastasis (p<0.05). Age above 55 years was statistically significantly associated (p<0.05) with the presence of negative prognostic factors in the study. 

Conclusions: The analysed histopathological and clinical prognostic factors were statistically significantly associated with lymphatic dissemination in endometrial cancer. We recommend treating endometrial cancer in tertiary centres by surgeons or gynaecologists-oncologists with experience in extensive peritoneal and retroperitoneal surgery.
