Background Primary gastric small cell carcinoma (GSCC) is a rare and aggressive disease for which the standard treatment has not been established. The objective of this study is to investigate the clinical characteristics and survival. Methods All cases of GSCC treated at our institute from January 1990 to December 2011 were reviewed and analyzed retrospectively. Statistical analyses were performed using Fisher's exact test. Results A total of 19 patients from 11,603 cases (0.16%) of all gastric cancers treated during this period were identified. The median age was 61 years and the patients were predominantly men. Using the latest AJCC Staging Criteria, the majority of the patients (68.4%) were Stage III. All patients underwent surgery. The median overall survival time (MST) was 19.5 months (95% CI 17.5–21.6 months). The 1‐, 3‐, and 5‐year overall survival rates were 77.3%, 44.2%, and 22.1%, respectively. The MST of 48.5 months for cases who received postoperative adjuvant chemotherapy was superior to that of 19.0 months for cases who did not ( P = 0.026). Conclusions Our data indicate that GSCC patients can be treated effectively with combined modality of treatment, despite the aggressive nature of GSCC. Systemic therapy, based on chemotherapy with surgery, is recommended. J. Surg. Oncol. 2012; 106: 994–998. © 2012 Wiley Periodicals, Inc.
