PURPOSE: Although rare, small-cell neuroendocrine carcinoma of the gynecologic tract (SCNCGT) is associated with poor prognosis. We analyzed the clinical characteristics, pathological features, treatment strategies, and prognosis in patients with SCNCGT.
PATIENTS AND METHODS: We performed a retrospective data analysis of 34 patients with SCNCGT diagnosed and treated at our hospital between 2006 and 2018. Medical records were reviewed for pathological features, treatment methods, and outcomes of this disease.
RESULTS: We included 34 patients who had small-cell neuroendocrine carcinoma of the endometrium (SCNCE; 7), ovary (SCNCO; 7), and cervix (SCNCC; 20). All patients with SCNCE underwent comprehensive surgery and six received postoperative chemotherapy. All patients with SCNCO received chemotherapy after surgery; six underwent comprehensive surgery and one underwent treatment only in the pelvic cavity. Sixteen patients with SCNCC underwent radical surgery and received chemotherapy, two of whom received simultaneous radiotherapy. The remaining four patients with SCNCC underwent comprehensive chemotherapy and radiation therapy. Among the 34 patients, 11 had vascular metastases, 15 had lymph node metastases, and seven exhibited positive margins. The median overall survival time among all patients was 23.18 months (range: 3-66 months). Death occurred in 18 cases (52.94%). Recurrence was observed in 13 cases (38.24%). The average time to recurrence was 15.78 months following treatment (range: 2-30 months). All 34 patients were evaluated for neuroendocrine markers. The immunohistochemical positive rates of synaptophysin, CD56, and chromogranin A were 73.5%, 64.7%, and 55.9%, respectively.
CONCLUSION: The rates of metastasis and recurrence are high, and prognosis remains poor, even among patients with early-stage SCNCGT. Our data may aid in the development of reference standards for diagnosis and treatment.
