目的总结胰腺浆液性囊腺瘤的临床特点、诊治及预后情况。 方法对我院2003年6月至2013年6月期间收治的19例胰腺浆液性囊腺瘤患者的临床资料进行回顾性分析。 结果胰腺浆液性囊腺瘤好发于中老年女性（本组男女比例为1:3.75，发病平均年龄56.7岁）。患者首发症状：腹部疼痛不适12例，发现腹部包块2例，无特殊症状因体检发现5例。肿瘤部位：胰头及胰颈部8例，胰体部6例，胰尾部5例。肿瘤平均直径5.4 cm。CT及MRI术前诊断率分别为60.0%（9/15）、80.0%（8/10）。19例患者均成功手术并行病理检查，其中浆液性微囊性腺瘤15例，浆液性寡囊性腺瘤4例。有4例患者术后出现胰漏，其中1例合并腹腔感染，经内科治疗后痊愈。术后随访4～124个月，平均55个月，未见肿瘤复发。 结论胰腺浆液性囊腺瘤的临床表现无特异性，CT及MRI术前诊断价值较高。手术为最有效的治疗方法，预后良好。
ObjectiveTo investigate the expression of ubiquitin-specific protease 9X (USP9X) in pancreatic cancer, and to evaluate the correlation of USP9X with the survival of patients with pancreatic cancer. MethodThe expression of USP9X was detected in 55 pieces of surgically resected primary pancreatic cancer tissues and adjacent nontumorous pancreatic tissues by streptavidin-perosidase immunohistochemical method. ResultsThe rate of USP9X high expression in the 55 pieces of the primary pancreatic cancer tissues was 58.2% (32/55), which in the adjacent nontumorous pancreatic tissues was zero. The expression of USP9X was not correlated with the gender, age, tumor position, or tumor size (P > 0.05), while which was significantly correlated with the differentiation degree, lymph node metastasis, or TNM stage (P < 0.05). By using Cox proportional hazard model, the multivariable analysis revealed that the differentiation degree, lymph node metastasis, and USP9X expression were the independent risk factors. Survival of the patient with USP9X high expression was significantly shorter than that with USP9X low expression (P < 0.05), and there was the same result in the patients with stageⅡ, with lymph node negative, or intermediate differentiation degree (P < 0.05). ConclusionThe results indicate that USP9X might play an important role in the pathogenesis and prognosis of pancreatic cancer.
