Objective: To compare the long-term oncological outcome of neoadjuvant chemotherapy before radical surgery (NCRS) and definitive chemoradiotherapy (DR) for stage IB2 and IIA2 cervical squamous cell carcinoma. Methods: The clinical outcome of 480 patients with stage IB2 and IIA2 cervical cancer (308 clinical responders, 111 clinical non-responders, 61 unclear) who underwent NCRS (and subgroup assessments) were compared with those of 233 patients who underwent DR. Results: The clinical response rate was 73.5% in the NCRS group. Multivariate COX regression analyses revealed that NCRS was not correlated with the 5-year overall survival (OS) rate (p = 0.067) or disease-free survival (DFS) rate (p = 0.249). In a subgroup of NCRS, the clinical response group was also shown to be a protective independent factor of 5 year OS rate compared to the DR group (aHR, 0.403; 95% CI, 0.209–0.777), but had no correlation with the 5 year DFS rate (p = 0.089). On the other hand, the clinical non-response group had no correlation with the 5 year OS rate (p = 0.780) or DFS rate (p = 0.669). Conclusion: Clinical responders who underwent NCRS exhibited a better oncological outcome compared to those who underwent DR.
