Abstract

Background: Endometrial cancer (EC) is a commonly occurring cancer among post-menopausal women. Pre-treatment imaging of the extent of disease can influence the decisions in the management of EC. MRI with its diffusion weighted (DW) images can help in better depiction of the primary tumour, its local extension and extrauterine spread to the peritoneum and lymph nodes. This study was conducted to know the role of MRI for pre-operative staging of endometrial cancer and as a guide for pelvic lymph nodal dissection.
Methodology: It was a descriptive cross-sectional study conducted at a tertiary care hospital patients diagnosed with primary endometrial adenocarcinoma on biopsy. Patients with advanced disease requiring chemotherapy prior to surgery were excluded. Fifty consecutive patients were subjected to MRI Pelvis with abdominal screening in the week preceding definitive surgery, Findings from imaging were compared with final histopathology for concurrence on tumour size, depth of myometrial invasion, presence of adnexal, nodal and cervical stromal involvement.
Results: Majority of the patients in this study were post-menopausal women. Sensitivity of MRI for staging of Endometrial Carcinoma in this study was 91.84% and Accuracy was 90%. When compared to HPE for lymph node positivity, MRI had sensitivity of 100%, specificity of 97.87%, PPV of 75%, NPV of 100% and accuracy of 98%.
Conclusion: Pre-operative MRI in the week prior to the planned surgery can help in accurately staging the endometrial carcinoma in terms of myometrial infiltration, cervical stromal infiltration as well as pelvic lymph nodal involvement.
