Pathological response on surgical samples is an independent prognostic variable for patients with Stage Ib2–IIb cervical cancer treated with neoadjuvant chemotherapy and radical hysterectomy: An Italian multicenter retrospective study (CTF Study)

• Neoadjuvant chemotherapy to surgery is an alternative option to chemoradiation for locally advanced cervical cancer.
• Pathological response rate correlates with survival.

ObjectivesThe purpose of this retrospective multicenter study was to correlate patterns of recurrences and clinical outcome of cervical cancer patients who underwent neoadjuvant chemotherapy [NACT] to surgery.MethodsThis study was conducted on 333 patients with FIGO stage Ib2–IIb cervical cancer who underwent NACT to surgery with pelvic lymphadenectomy. The median follow-up was 66.5 months (range, 8–212 months). Overall optimal response rate was the sum of complete and optimal partial response rates.ResultsAn overall optimal response was obtained in 64 patients (19.2%). As for the 220 sub-optimal responders (66.1%), 127 patients had negative nodes and negative parametria and/or surgical margins, 75 patients had positive nodes with positive or negative parametria and/or surgical margins, and 18 patients had positive parametria and/or surgical margins with negative nodes. At the time of the present analysis, 79 (23.7%) of the 333 patients had a recurrence after a median time of 14.9 months (range, 4.5–123 months). Recurrent disease was pelvic in 50 (63.3%), extra-pelvic in 22 (27.9%), and both in 7 (8.8%). On multivariate analysis, pathological response to NACT was an independent prognostic variable for recurrence-free and overall survival. Patients who did not achieve an overall optimal response had a 2.757-fold higher risk of recurrence and a 5.413-fold higher risk of death than those who obtained an overall optimal response.ConclusionsResults appear to suggest that the chemo-surgical approach is an effective therapeutic option for patients with stage Ib2–IIb cervical cancer and that pathological response to NACT is the strongest prognostic factor for the outcome.
