Is magnetic resonance imaging useful in early evaluation of women on neoadjuvant chemotherapy for locally advanced cervical cancer?

To evaluate the accuracy of magnetic resonance imaging (MRI) in staging cervical tumors after neoadjuvant chemotherapy (NACT).26 women, affected by locally advanced cervical cancer and triaged for surgery after NACT, were submitted to three cycles of neoadjuvant chemotherapy. All patients were submitted to MRI before and after NACT. We evaluated the MRI sensitivity and specificity in staging cervical tumors after chemotherapy, relating MRI findings after NACT with the pathological findings as the gold standard.In our series, MRI sensitivity was 58.8% and specificity was 66.7%.In our study MRI accuracy after NACT was lower than that of MRI used to stage patients with early cervical cancer scheduled for primary surgery, reported by the literature. MRI false negative cases are the major problem because of the delay in application of an effective therapy in non responders to NACT.
