概括
这项研究显示了周围癌亚型的明显差异,包括肠腺癌 (AmpIT) 和十二指肠腺癌 (DAC),这些亚型的生存率更高. 对每个亚型的个别评估对于未来的研究和治疗至关重要.
科学领域:
- 胃肠道学和外科瘤学
- 癌症研究和病理学
背景情况:
- 周围癌症,包括胰腺管腺癌 (PDAC),远端胆管腺癌 (dCCA),十二指甲腺癌 (DAC) 和囊癌,共享解剖近距离,但表现不清楚的差异.
- 腹膜癌在组织病理学上被分为肠道 (AmpIT),胰腺胆道 (AmpPB) 和混合亚型,对其与其他腹膜周癌症的关系的了解有限.
研究的目的:
- 为了比较瘤特征和长期存活在不同的异位病理学亚型的周围瘤癌症.
- 调查手术前血液标记物 (CA19-9),病理和十二指腺癌 (DAC),肠 (AmpIT),胰腺 (AmpPB),远端胆管癌 (dCCA) 和胰腺管腺癌 (PDAC) 之间的关系和整体存活率.
主要方法:
- 一项国际队列研究,涉及3809名患者,他们在2010年至2021年期间接受了围癌的治疗意图切除.
- 在DAC,AmpIT,AmpPB,dCCA和PDAC患者组中比较手术前CA19-9水平,病理结果和8年整体存活率.
主要成果:
- AmpIT和DAC显示出最高的8年整体存活率 (49.8%和47.9%),明显优于AmpPB (34.9%),dCCA (26.4%) 和PDAC (12.9%).
- 较低的手术前CA19-9水平与更好的生存率相关,而瘤大小没有显示出显著的生存相关性,DAC病变是最大的.
- 瘤特征和生存模式表明DAC和AmpIT之间,以及AmpPB和dCCA之间,而不是囊亚型之间更密切的关系.
结论:
- 在这五种围癌亚型中,在术前标志物,病理和长期存活率方面存在显著差异.
- 该研究强调,DAC和AmpIT与AmpPB和dCCA一样具有更多的共同特征,这挑战了囊亚型的分组.
- 建议对每个组织病理学亚型进行个别评估,而不是对"周边脉癌"的集体定义进行评估,以便在未来进行研究和临床考虑.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

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.
