    Abstract:
    The aim of the study is to evaluate the efficacy of postoperative treatments based on pathological response for cervical cancer patients who received neoadjuvant chemotherapy (NACT) followed by radical surgery. Firstly, a total of 756 cervical squamous cell cancer (SCC) patients with FIGO IB2-IIB were included in this retrospective study. Then data from a prospective cohort of 393 patients was employed for further validation. Overall survival (OS) and disease-free survival (DFS) were assessed. In the retrospective study, SCC patients who accepted adjuvant chemotherapy after radical surgery had a relatively better OS than those who received no therapy (P = 0.08, HR = 0.57). The result was more noticeable in the prospective cohort study (P = 0.006, HR = 0.28). In the combined analysis, adjuvant chemotherapy improved clinical outcomes compared with no therapy (P = 0.002 and 0.04 for OS and DFS). Particularly for patients with extra-cervical residual disease, adjuvant chemotherapy improved OS (log-rank P = 0.008, 0.004 and 0.001 in the retrospective, prospective and combined studies). Optimal response patients had good outcomes even without therapy. Our study indicates that adjuvant chemotherapy can benefit clinical outcomes for SCC patients with NACT followed by radical surgery, especially those with extra-cervical residual disease. For optimal response patients, there may be no need for further treatment. This finding needs to be validated in more future studies.
