简介：目的：探讨Ⅰb～Ⅱb期宫颈癌术前放疗的优势及放疗后的手术适应症。方法：37例Ⅰb～Ⅱb期宫颈癌接受术前放疗后行广泛性子宫切除加盆腔淋巴结清扫术。结果：全组病人均能如期按手术规范完成手术，术中未发生不可控制的大出血，无输尿管、膀胱、直肠等损伤发生。术后常见并发症发生率低。结论：Ⅰb～Ⅱb期宫颈癌经术前放疗，降低了手术难度，并使Ⅱb期病人具有手术机会，且不增加术中术后并发症的发生。

简介：目的总结胃肠道间质瘤的诊断及治疗经验。方法回顾分析2000年3月至2008年5月间大连医科大学附属第二医院普外科住院治疗的37例胃肠道间质瘤患者的临床资料。结果本组37例均行手术治疗，手术切除率100％，无手术并发症及手术死亡者；术后免疫组化结果CD117阳性97.2％，CD34阳性率86.5％，CD117与CD34共同阳性率83.8％。结论胃肠道间质瘤临床表现无特异性，术前明确诊断较困难，手术治疗为主要治疗手段，根据术后病理学检查可明确诊断。
