Abstract
BACKGROUND: Research on the clinicopathology and prognosis of gastric neuroendocrine carcinoma (GNEC) is rare, and a uniform standard for treatment has not been established. Therefore, we retrospectively analyzed the clinical data of 132 cases of GNEC to investigate the factors influencing prognosis. METHODS: A total of 132 patients diagnosed with GNEC at Fujian Medical University Union Hospital from January 2006 to December 2013 were enrolled. This study was performed to analyze the factors related to patient prognosis. RESULTS: In total, 58 men and 74 women whose ages ranged from 38 to 83 years old (62 ± 10) were enrolled. The 1- and 3-year survival rates for these patients were 83.9% and 47.6%, respectively. Of these patients, 100 underwent radical resection, 22 underwent palliative resection, and 10 received chemotherapy alone. The median survival times following radical resection, palliative resection and chemotherapy alone were 48, 20 and 12 months, respectively (P < 0.01). Univariate and multivariate survival analyses of patients who underwent radical resection showed that tumor size, N stage, Ki-67 labeling index, mitotic index and the application of postoperative adjuvant chemotherapy were independent factors affecting patient prognosis. The correlation analysis of the Ki-67 labeling index and mitotic index with prognosis showed that patient survival decreased significantly when the Ki-67 labeling index increased (P < 0.05). CONCLUSIONS: Patients who underwent radical resection had the best prognosis among GNEC. For these patients, tumor size, N stage, Ki-67 labeling index, mitotic index and the application of postoperative adjuvant chemotherapy were the clinicopathological factors significantly associated with patient prognosis.
