Abstract Background: This study was aimed to determine the effect of neoadjuvant chemotherapy consisting of nab-paclitaxel and cisplatin (NACT-nPC) in patients with locally advanced cervical cancer.Materials and Methods: The consecutive, newly diagnosed, non-metastatic and locally advanced cervical cancer patients were retrospectively recruited between October 2016 and June 2020 in our hospital. All patients received concurrent chemoradiotherapy alone or following neoadjuvant chemotherapy. Patients were divided into two groups: one receiving NACT-nPC, and the control group receiving no or other regimes of neoadjuvant chemotherapy. We compared the complete remission rate of primary tumor at the end of external radiotherapy and chemoradiotherapy between the two groups. Results: A total of 198 patients were enrolled in this study, including 60 in NACT-nPC group and 138 in control group. At the end of external radiotherapy, 27 patients in NACT-nPC group and 32 patients in control group achieved complete remission (P = 0.002). At the end of chemoradiotherapy, 56 patients in NACT-nPC group and 114 patients in control group achieved complete remission (P = 0.033). The acute side effects above grade 3 in NACT-nPC group was 41.7% (25/60) and manageable, lower than control group which was 77/138 (55.8%).Conclusions: NACT-nPC can improve the complete response rate of patients with locally advanced cervical cancer followed by concurrent chemoradiotherapy, and the toxicity is tolerable. Furthermore, we suspect the NACT-nPC can improve the survival of the patients. However, further prospective studies are needed to confirm this result.

6030 Background: Neoadjuvant is a promising chemotherapy modality for recurrent nasopharyngeal carcinoma (NPC). However, there is still controversy for locally advanced NPC. We study the survival results of locally advanced NPC treated with neoadjuvant chemotherapy followed by concurrent chemoradiotherapy (NACT) retrospectively, and to explore the potential beneficiaries. Methods: 147 stage III-IVa+b NPC treated with IMRT were included and divided into two groups. NACT group (76) received 2-3 cycles of neoadjuvant chemotherapy with TP or TPF, and then 2-3 cycles of platinum-based chemoradiotherapy (CCRT). CCRT group (71) received 3 cycles of platinum-based chemoradiotherapy. TNM stage, age and whole blood count before treatment were all collected. The stratified analysis was used for distinguishing the potential beneficiaries. Results: median follow-up time was 30 months. For all patients, the 3-year LRRFS, DMFS and OS in NACT and CCRT were 94.5%, 96.8%; 85.8%, 82.8% and 81.6%, 83.4% respectively ( p> 0.05). For stage III patients, the 3-year LRRFS, DMFS and OS were 95.2%, 97.3%; 91.4%, 84.6% and 86.3%, 82.1% respectively ( p= 0.38, p= 0.15, p= 0.58). Though there was no statistical significance, DMFS in NACT was better than it in CCRT. However, for stage IV, the survival rate had no significant difference. The incidence of grade 3-4 bone marrow suppression was higher in NACT ( p= 0.007), and the other toxicities were similar. Univariate analysis showed the percentages of neutrophil and neutrophil-to-lymphocyte ratio (NLR) were significantly correlated with OS ( p= 0.031, p= 0.049). N and clinical stage were the adverse prognostic factors for OS ( p= 0.025, p= 0.007) and DMFS ( p= 0.018, p= 0.001). Clinical stage was the prognostic factors for OS and DMFS in multivariate analyses ( p= 0.019, p= 0.01). Conclusions: NACT had a comparable survival results and tolerable toxicity with CCRT for locally advanced NPC. Stage III might be the potential beneficiaries from NACT, especially for DMFS. Percentages of neutrophil and NLR might be the new adverse prognostic factor for OS. Clinical stage was still the prognostic factor for OS and DMFS.
