Clinicopathological Analysis of Carcinoma Endometrium at a Tertiary Care Centre in Chennai – A Retrospective Study

Abstract

BACKGROUND Endometrial carcinoma is a leading malignancy among females. Pre-operative imaging and biopsy are necessary to identify the disease. Clinicopathological analysis determines the extent of the disease. Complete surgical staging is advised for high-risk patients. The purpose of this study was to analyze the different clinical endpoints, prognostic factors and demographic details that will influence the survival patterns of the cases of carcinoma of endometrium who underwent surgery during the period from 2014 to 2017 at a tertiary care centre, Chennai, India. METHODS Patients diagnosed with operable endometrial carcinoma were surgically staged based on the surgical procedures performed namely, total abdominal hysterectomy (TAH) with bilateral salphingo-oophorectomy (BSO), bilateral pelvic lymph node dissection, and para-aortic lymphadenectomy (patients with high-risk features). Post-surgical staging specimens were histopathologically examined in the Department of Pathology. Adjuvant radiation was given to patients with stage IA grade II and above. Patients with stage III disease received adjuvant chemotherapy. Descriptive analysis was done to show the distributions of patients accordingly. Kaplan-Meier survival analysis was performed for the overall median survival of the patients. RESULTS The study consisted of a total of 35 patients with a mean age of 56 ± 8.64. Parameters such as age, clinicopathological features, stage (FIGO staging), tumor size, grade, lymphovascular invasion (LVI), myometrial invasion, cervical involvement, involvement of margins, lymph node ratio (LNR) and survival were studied. Tumor size and grade were found to be significant factors affecting the survival. Overall median survival period of patients who underwent surgery was found to be 31 months. CONCLUSIONS Tumor size and grade of the tumor are significant prognostic factors affecting the survival of the patients with carcinoma of endometrium. Lymph node ratio is a new concept in carcinoma endometrium to be pondered upon as a factor predicting survival in future studies thereby defining the role of lymph node dissection in surgical staging.
