Comparative Study Between Superficial and Deep Myometrial Invasion in Endometrial Cancer Type 1 in Relation to Regional Lymph Nodes Metastasis

Abstract

Background & Objective: The present study compares between superficial and deep myometrial invasion in type 1 endometrial cancer in relation to regional lymph nodes metastasis, so we can answer the question to do or not do lymphadenectomy, this lifethreatening procedure in both superficial and deep myometrial invasion with type 1, clinically and radiologically stage 1 endometrial cancer.Materials & Methods: Patients were divided into 2 groups distributed as follows: group I includes 50 patients type 1 endometrial cancer with superficial myometrial invasion and group II includes 50 patients type 1 endometrial cancer with deep myometrial invasion. Total abdominal hysterectomy with bilateral salpingo-opherectomy with pelvic and lower para-aortic lymphadenectomy to all patients included in the study from both groups. Histopathological examinations were done to all the specimen from both groups to confirm diagnosis of type 1 endometrial cancer, depth of myometrial invasion, pathological grading and metastasis to the regional lymph nodes.Results: Considering regional lymph nodes metastasis in both groups, there is a statistical difference between group I and group II in relation to regional lymph nodes metastasis as group II (cases with deep myometrial invasion) are associated with more regional lymph nodes metastasis (P= 0.0001)). Conclusion:Deep myometrial invasion in type 1 endometrial cancer is associated with significant increase in regional lymph nodes metastases.
