Abstract

Background To evaluate the feasibility and the predictive value of cone biopsy before performing radical hysterectomy in locally advanced cervical cancer patients showing complete clinical response to neo-Adjuvant chemoradiation. Methods Between March 2010 to March 2012 74 consecutive FIGO stage IIA2-IIB patients were submitted to neo-Adjuvant chemoradiation. All complete clinical responder patients were enrolled in this pilot trial. Results Fifty-seven out of 74 patients (77%) showed complete clinical response and were enrolled in the study. Forty-two out of 57 patients (74%) underwent successful pre-completion surgery cone biopsy with a median cone's tissue diameter of 24 mm (range 18-35). In 33 out of 42 patients (58%) a complete pathological response was found. In the remaining 5 (9%) and 4 (7%) a microscopic partial and partial response was found, respectively. All 33 cases (58%) with negative cone showed complete pathological response in the radical hysterectomy specimens. Patients with microscopic residual tumor foci in the cone showed negative residual cervical and paracervical tissue at definitive diagnosis, whereas in patients with partial response macroscopic residual disease in the surgical specimens was found. The negative predictive value of cone biopsy, MRI and PET/CT in the prediction of pathological status of the cervical and paracervical tissue was 100%, 79% and 79%, respectively (Table 2). Conclusions In this study we observed that, in locally advanced cervical patients showing complete clinical response to neo-Adjuvant chemoradiation, the cone biopsy feasibility was almost 75%, and that there is a complete pathological correspondence between cone and definitive pathology.
