概括

胰腺的未分化类癌 (USCP) 是罕见的,预后不佳. 远程转移和介质门轴入侵与切除USCP患者的较差结果有关.

科学领域:

在瘤学瘤学.
胃肠病学胃肠病学
手术病理学手术病理学

背景情况:

胰腺无差异性类癌 (USCP) 是一种罕见的胰腺恶性瘤,临床行为和手术结果不明.
关于切除USCP病例的特定特征和生存率的数据有限.

研究的目的:

阐明切除USCP的患者的组织学,临床病理学特征和术后结果.
评估整体生存 (OS) 并确定与胰腺切除术后USCP相关的预后因素.

主要方法:

对23名被诊断患有USCP的患者进行了回顾性分析,这些患者在一个机构接受了胰腺切除术.
详细审查患者的人口统计学,瘤组织学,手术程序,术后并发症和长期生存数据.

主要成果:

23名患者的中位年龄为61.5岁;在21例中实现了R0切除.
1年,3年和5年的生存率分别为43.5%,4.8%和4.8%,平均生存时间为9.0个月.
远程转移和中腔门轴入侵独立地与差 OS (p<0.01) 相关.

结论:

USCP是一种罕见的胰腺恶性瘤,预后不佳,缺乏特定的成像发现,需要病理诊断.
准确的诊断依赖于活检和免疫组织化学,经常显示表皮和介质细胞标记物的共同表达.
早期死亡是常见的,特别是在远程转移和中腔门轴入侵的情况下;切割后的长期存活很少.

关键词:

Cancer

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
