AIM: To compare the demographics and survival rates between gallbladder adenocarcinoma(GB-adenocarcinoma) and small cell neuroendocrine carcinoma of the gallbladder(GB-NEC-SCC).METHODS: From March 2007 to September 2012,patients who underwent resection of tumor stage T2/T3 GB cancer were enrolled for this study.Fortytwo patients were included in this study,including 38 diagnosed with GB-adenocarcinoma and four diagnosed with GB-NEC-SCC.In the GB-adenocarcinoma group,a radical operation was performed in 28 patients,and ten patients underwent simple cholecystectomy.In the GB-NEC-SCC group,a radical operation was performed in three patients,and one patient underwent simple cholecystectomy.Comparative analysis of the two groups was performed,including clinicopathologic features and survival rates.RESULTS: The median age of the patients was 68 y(range: 35-83 years) and females comprised 26/42 of the patients.GB-adenocarcinoma patients were significantly older than GB-NEC-SCC patients(67.89 ± 11.15 vs 55.75 ± 10.31 years; P = 0.029).The median tumor size in GB-adenocarcinoma patients was 2.56 ± 1.75 cm and 3.98 ± 3.74 cm in GB-NEC-SCC patients; however,there was no significant difference between the two groups.For tumors > 2 cm,T stage(T2 vs T3),lymphovascular invasion,perineural invasion,lymph node metastasis and lymph node ratio showed no significant differences between the two groups.The overall survival rate of the 42 patients at five years was 77.0%.In the GB-adenocarcinoma group,the overall five-year survival rate was 74.8%,and survival in the GB-NEC-SCC group was 100%,which was not significantly different between the two groups.CONCLUSION: The strategy for treating patients with GB-NEC-SCC should be similar to that used for treating GB-adenocarcinoma,including radical cholecystectomy and liver resection.
