Background: Neuroendocrine cervical carcinoma (NECC) is a rare and highly aggressive gynecological tumor, with poor prognosis and limited standardized treatment options. Inflammation plays a significant role in tumor progression, and systemic inflammatory markers such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) have shown prognostic value in other malignancies. However, their role in NECC remains unclear. Methods: This single-center retrospective study included 25 NECC patients treated at our hospital between 2014 and 2024. Patients were divided into three groups based on treatment regimens: paclitaxel plus cisplatin combined with radiotherapy, etoposide plus cisplatin combined with radiotherapy, and radiotherapy alone. Baseline characteristics, inflammatory markers, and clinical outcomes were analyzed. Kaplan-Meier survival analysis and Log-rank tests were used to compare survival differences.The median survival time was significantly longer in the etoposide plus cisplatin plus radiotherapy group (1,000 days) compared to the paclitaxel plus cisplatin plus radiotherapy group (776 days) and the radiotherapy-alone group (347 days, P = 0.037). The radiotherapy-alone group had significantly higher neutrophil counts (median = 5.46×10⁹/L, P = 0.006), platelet counts (median = 282.5×10⁹/L, P = 0.017), NLR (median = 4.68, P < 0.05), and PLR (median = 231.93, P < 0.05), while LMR (median = 1.89, P < 0.05) was lower. For postoperative patients, the median survival time was 1,453 days for the surgery plus etoposide plus cisplatin plus radiotherapy group, compared to 987 days for the surgery plus paclitaxel plus cisplatin plus radiotherapy group (P = 0.048).Combined chemotherapy with etoposide plus cisplatin and radiotherapy significantly improves survival outcomes in NECC patients compared to radiotherapy alone. This regimen may be particularly beneficial for postoperative patients and those with high-risk factors such as lymphovascular space invasion. Further studies are needed to validate these findings and establish standardized treatment protocols for NECC.
