背景情况:

结肠癌是全球癌症相关死亡的主要原因.
目前的治疗方法有局限性,免疫疗法只对一小部分患者有益.
了解瘤免疫微环境对于开发新疗法至关重要.

研究的目的:

研究IL22RA1,IL22,CD155和IL22BP在结肠癌中的表达模式和预后意义.
评估IL22RA1作为结肠癌预后生物标志物和治疗点的潜力.

主要方法:

主要成果:

在结肠癌组织中,IL22RA1,CD155和IL22BP的表达明显高于正常组织.
高IL22RA1表达与明显更差的整体存活率 (OS) 相关.
IL22RA1与IL22或CD155的同时表达预测了较差的生存状况,而低IL22RA1与高IL22BP预测了更好的生存状况.
高IL22RA1表达与关键T细胞子集的透率降低相关,包括CD8+和CD4+T细胞.

结论:

在结肠癌中IL22RA1表达升高是预后不佳的独立风险因素.
IL22RA1与IL22和CD155的相互作用可能驱动瘤发生并影响患者的结果.

Tumor Progression

Tumor Progression

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...
