OBJECTIVETo summarize and analyze the clinical feature, therapeutic methods and prognosis of gastric small cell carcinoma (SCC).

METHODSThe clinical and pathological data of 41 patients diagnosed of gastric SCC were analyzed in this research. Also, the factors which may potentially affect the patients' survival outcome were evaluated. There were 35 male and 6 female patients. The age at diagnosis was 39-84 years, median age was 62 years. The 31 cases (75.6%) of gastric SCC patients were involved in the upper third of the stomach, 3 cases (7.3%) in the middle, 7 cases (17.1%) in the lower third.

RESULTSThe time from the event of symptoms to final confirmation was 1 to 13 months, the median time was 3 months. The longest diameter of tumors was from 2.5 to 15.0 cm, the average was 6.5 cm. The 38 cases (92.7%) chosed surgery as the first treatment, among which 25 cases (61.0%) were performed radical tumor resection, 13 cases (31.7%) went through palliative resection, and 3 cases (7.3%) just employed chemotherapy. The initial II, III, IV stage were 2, 31 and 8 cases, respectively. The overall median survival time was 19 months, median disease free survival time was 11 months, 1-, 2-, 5-years survival rates were 70.7%, 46.3% and 36.6%, respectively. In univariate survival analysis, the tumor size (χ² = 5.565), change of the body weight (χ² = 3.688), type of operation (χ² = 11.747) and relapse or not (χ² = 17.966) were obviously correlaed with the prognosis (P < 0.05).

CONCLUSIONSGastric SCC is a rare disease of the gastrointestinal tract, the misdiagnosis rate is high, and the prognosis is dismal. Muti-modality management, with radical surgical resection of the primary lesion followed by standard adjuvant-chemotherapy, affords better local disease control and a better survival outcome.
