Abstract:Objective To investigate the relationship between the expression of Jagged 2 protein (JAG2), inhibin βA (INHBA), programmed cell death-ligand 1 (PD-L1) and prognosis in elderly patients with colorectal cancer. Methods A total of 112 elderly patients with colorectal cancer who received surgical treatment in Hunan Cancer Hospital from May 2017 to May 2019 were selected as the study objects. JAG2, INHBA, and PD-L1 expression in cancer tissues and adjacent tissues were detected by immunohistochemical method. The survival time of patients was followed up, and the relationship between JAG2, INHBA, PD-L1 expression and prognosis of elderly patients with colorectal cancer was analyzed by Cox regression model.Results The positive expression rates of JAG2, INHBA, and PD-L1 in cancer tissues were higher than those in adjacent tissues, and the differences were statistically significant (P<0.05). The positive expression rates of JAG2, INHBA, and PD-L1 in poorly differentiated patients were higher than those in middle and highly differentiated patients, and the positive expression rates of JAG2, INHBA, and PD-L1 in patients with TNM stage Ⅲ-Ⅳ were higher than those in patients with stage Ⅰ-Ⅱ (P<0.05). Cox regression model showed that low tumor differentiation, TNM stage Ⅲ-Ⅳ, JAG2, INHBA, and PD-L1 expression were independent risk factors for progression-free survival in elderly patients with colorectal cancer (OR>1, P<0.05). The overall survival rate of JAG2, INHBA, and PD-L1 negative patients with colorectal cancer were higher than those of JAG2, INHBA, and PD-L1 positive patients, and the differences were statistically significant (P<0.05). The progression-free survival rate of JAG2, INHBA, and PD-L1 negative patients were higher than those of JAG2 positive patients, and the differences were statistically significant (P<0.05). Conclusion The positive expression rates of JAG2, INHBA, and PD-L1 in cancer tissues of elderly patients with colorectal cancer are high, which is of great significance for prognosis evaluation.
