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).

The 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. This 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. An 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. Results 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.

Is there a role for postoperative treatment in patients with stage Ib2-IIb cervical cancer treated with neo-adjuvant chemotherapy and radical surgery? An Italian multicenter retrospective study.

Neoadjuvant chemotherapy [NACT] followed by radical hysterectomy is an alternative therapeutic option to concurrent chemotherapy-radiotherapy for locally advanced cervical cancer. However there are very few data about the effectiveness of any post-operative treatment in this clinical setting. The purpose of this study was to correlate the patterns of recurrence and the clinical outcomes of cervical cancer patients who received NACT, with postoperative adjuvant treatment. This retrospective multicenter study included 333 patients with FIGO stage Ib2-IIb cervical cancer who underwent platinum-based NACT followed by radical surgery. Pathological responses were retrospectively assessed as complete; optimal partial; and suboptimal response. Overall optimal response rate was the sum of complete and optimal partial response rates. On the whole series, recurrence-free survival was significantly longer in patients who achieved an overall optimal response than in those who did not (p<0.0001), and in patients who received adjuvant chemotherapy compared to those who did not (p=0.0001). On multivariate analysis, consolidation therapy (p=0.0012) was the only independent prognostic variable for recurrence-free survival; whereas FIGO stage (p=0.0169) and consolidation therapy (p=0.0016) were independent prognostic variables for overall survival. Optimal responders after chemo-surgical treatment for FIGO stage Ib2-IIb cervical cancer do not need any further treatment. Additional cycles of chemotherapy could be of benefit for patients with suboptimal response and intra-cervical residual disease. Both adjuvant chemotherapy and adjuvant radiation treatments do not seem to improve the clinical outcome of patients with extra-cervical residual disease compared to no further treatment.

Neoadjuvant Platinum-based Chemotherapy Followed by Radical Hysterectomy for Stage Ib2-IIb Adenocarcinoma of the Uterine Cervix - An Italian Multicenter Retrospective Study.

To assess the patterns of recurrence and clinical outcomes of patients with cervical adenocarcinoma who underwent neoadjuvant platinum-based chemotherapy (NACT) followed by radical hysterectomy. Data were retrospectively analyzed for 82 patients with International Federation of Gynecology and Obstetrics stage Ib2-IIb cervical adenocarcinoma who underwent this chemo-surgical treatment. The median follow-up of survivors was 89 months (range=5-208 months). Pathological complete response, optimal response and suboptimal response with intra-cervical residual disease were obtained in five (6%), 10 (12%) and 36 (44%) patients, respectively. Adjuvant external-beam radiotherapy with or without concurrent chemotherapy was administered to 47 patients. Nineteen (23%) out of the 82 patients experienced recurrence after a median of 12 months (range=5.3-86.8 months). Recurrent disease was pelvic in 12 (63%) patients, extra-pelvic in five (26%), and both pelvic and extra-pelvic in two (10%). According to pathological response, tumor relapsed in 10% of optimal responders, 14% of sub-optimal responders with intra-cervical residual disease, and 36% of sub-optimal responders with extra-cervical residual disease or non-responders. Five-year recurrence-free and overall survival were 77% and 84%, respectively. Patients who achieved an optimal response or sub-optimal response with intra-cervical residual disease had better 5-year recurrence-free (87% vs. 64%, p=0.017) and overall (92% vs. 74%, p=0.012) survival than those who had sub-optimal response with extra-cervical residual disease or no response. The latter had a 1.441-fold higher risk of recurrence and a 1.652-fold higher risk of death than those who obtained an optimal response or a sub-optimal response with intra-cervical residual disease. NACT followed by radical hysterectomy may be an option for patients with stage Ib2-IIb adenocarcinoma of the uterine cervix.
