Diagnostic Accuracy of MRI With Clinical Staging in Cervical Cancer

Cervical cancer is the fourth most common cancer among women worldwide. The aim of this study was to evaluate the role of magnetic resonance imaging (MRI) in the assessment of extension and staging of cervical malignancy and comparison with clinical staging. Materials and Methods: This prospective study was conducted on 50 newly diagnosed patients with cervical cancer at a tertiary care centre at IGIMS, Patna. Patients were examined and staged according to FIGO system. MRI was done in each patients. Then we compared the predicted stage for each patient with the two methods. Results: Based on clinical staging twelve patients (24%) were observed at stage 1, MRI staging was in coordination with clinical staging in eight of them while three patient were staged 2b, and one patient was staged IIa on MRI. Based on the clinical staging four patients (08%) were diagnosed as stage 2a. MRI staging was in coordination with clinical staging in three cases and one was staged Ib. Based on clinical staging 18 patients (36%) were stage 2b. MRI staging was in coordination with clinical staging in fifteen of them and for other two patients MRI diagnosed as stage IIIb and in one staged Ib. Based on clinical staging fifteen patients were stage 3b. MRI staging was in coordination with clinical staging in thirteen of them and for the two patient MRI diagnosed stage IVa. Based on clinical staging one patients (7.5%) was staged IVa. MRI staging was in coordination with clinical stage. MRI had a sensitivity of 100% and specificity of 81.26% in detection of parametrial infiltration, and sensitivity of 100% and specificity of 88.84% in detection of vaginal infiltration Conclusions: MRI is an optimal non-invasive modality but expensive for preoperative staging of uterine cervical malignancy, and crucial in subsequent more accurate treatment planning.
