The baseline characteristics of age, FIGO stage, histology, tumor differentiation, tumor size, and clinical outcomes, including post-operative pathological risk factors, overall survival (OS), and progression-free survival (PFS) were compared between the responders and non-responders.Results: The overall response rate was 58.9% (129/219), and 19 (8.7%) patients achieved pathologically complete remission. NACT responders showed significantly better OS and PFS than non-responders (POS= 0.002, PPFS= 0.002). The response to NACT was identified as an independent risk factor for OS (hazard ratio [HR] = 2.453, 95% confidence intervals [95% CI], 1.125– 5.348, P = 0.024) and PFS (HR = 2.196, 95% CI, 1.183– 4.076, P = 0.013), and patients with IB2/IIA1 and a tumor size of < 5 cm tended to receive better response than patients with IIA2 (P = 0.004) and a tumor size of ≥ 5 cm (P = 0.027).Conclusion: The response rate of platinum-based NACT was approximately 60%. The response to NACT was an independent risk factor for prognosis, and patients with earlier stage and smaller tumor tended to respond better to NACT.Keywords: locally advanced cervical cancer, neoadjuvant chemotherapy, clinical response, predictor, prognosis
