Background/Aim: We aimed to investigate the efficacy of immune-cell therapy in terms of the survival of patients with neuroendocrine carcinoma of the uterine cervix (NECC), which lacks standardized therapeutic approaches. Patients and Methods: We identified 17 patients who were diagnosed as having NECC and treated with immune-cell therapy. The clinical characteristics of these patients were extracted from their records and their overall survival was measured. Results: Of the 17 patients, two patients with earlystage NECC without recurrence and three patients with less than four treatments were excluded. The median survival times from the time of diagnosis and from the initial administration of immune-cell therapy were 49.7 and 24.4 months, respectively. The overall survival rates at 1, 2, and 5 years were 63.6%, 38.2%, and 25.5%, respectively. Long-term survival was observed in the patients with distant metastases. Conclusion: The preliminary results of this retrospective study suggested the potential efficacy of immune-cell therapy for NECC.Neuroendocrine carcinoma of the uterine cervix (NECC) is a rare malignant disease that accounts for less than 5% of all cervical cancer. NECC can be classified into small-cell, largecell, or mixed-cell type, all of which are aggressive, with early nodal and distant metastases, often resulting in a poor prognosis. In a study of 130 patients with small-cell NECC, the 5-year cancer-specific survival was reported to be 63% at
