摘要:

目的 探讨细胞色素P450 1B1(CYP1B1)和蛋白酶体26 S亚基非ATP酶14(PSMD14)在结直肠癌组织中的表达及其对结直肠癌预后的影响。方法 选取2021年1月—2022年6月入本院接受手术治疗的107例结直肠癌患者,手术过程中获取患者的癌组织和癌旁组织,qRT-PCR法检测癌组织和癌旁组织中CYP1B1和PSMD14 mRNA水平,分析CYP1B1和PSMD14水平与结直肠癌病理特征的关系,采用Cox回归模型分析生存预后的影响因素,受试者工作特征(ROC)曲线分析CYP1B1和PSMD14 mRNA水平在结直肠癌中的诊断价值。结果 结直肠癌组织中CYP1B1和PSMD14 mRNA表达明显高于癌旁组织(P<0.01);CYP1B1和PSMD14联合诊断的曲线下面积(AUC)和敏感度明显高于CYP1B1和PSMD14单独检测;肿瘤直径≥5 cm、TNM分期为Ⅲ+Ⅳ期、分化程度低、有淋巴结转移患者癌组织CYP1B1和PSMD14 mRNA高表达占比较高(均P<0.05);CYP1B1 mRNA高表达者3年总生存率(40.82%)明显低于CYP1B1 mRNA低表达者(89.09%),PSMD14 mRNA高表达的3年总生存率(34.04%)明显低于PSMD14 mRNA低表达者(92.98%),差异均有统计学意义(Log-rank χ2分别为26.070、43.060,均P<0.01);TNM分期为Ⅲ+Ⅳ期、低分化程度、有淋巴结转移、CYP1B1 mRNA高表达、PSMD14 mRNA高表达是结直肠癌患者生存预后的独立危险因素(P<0.05)。结论 CYP1B1和PSMD14 mRNA在结直肠癌组织中高表达,与疾病的进展和生存预后密切相关,对结直肠癌具有良好的诊断价值,可能成为评估结直肠癌患者治疗和生存预后的重要生物标志物。

Abstract:

Objective To explore the expression of cytochrome P450 1B1 (CYP1B1) and proteasome 26 S subunit non-ATpase 14 (PSMD14) in colorectal cancer tissue and their impact on the prognosis of colorectal cancer. Methods A total of 107 colorectal cancer patients who underwent surgery in our hostpital from January 2021 to June 2022 were selected in this study. Cancer tissue and adjacent tissue samples were obtained during surgery, and the mRNA levels of CYP1B1 and PSMD14 in cancer tissue and adjacent tissue were detected by qRT-PCR. The relationship between levels of CYP1B1 and PSMD14 and pathological characteristics of colorectal cancer was analyzed. The Cox regression model was used to analyze the influencing factors of survival prognosis. The diagnostic value of CYP1B1 and PSMD14 levels in colorectal cancer was analyzed using ROC curves. Results In colorectal cancer tissue, the mRNA expressions of CYP1B1 and PSMD14 were significantly higher than those in paracancerous tissue (P<0.01). The area under the curve (AUC) and sensitivity of the combined diagnosis of CYP1B1 and PSMD14 were significantly higher than those of the individual detection of CYP1B1 and PSMD14. The proportion of high CYP1B1 and PSMD14 mRNA expression in cancer tissue of patients with tumor diameter ≥5 cm, TNM stage Ⅲ+Ⅳ, low differentiation and lymph node metastasis were relatively high (P<0.05). The 3-year overall survival rate of patients with high mRNA expression of CYP1B1 (40.82%) was significantly lower than that of patients with low mRNA expression of CYP1B1 (89.09%). The 3-year overall survival rate of those with high expression of PSMD14 mRNA (34.04%) was significantly lower than that of patients with low expression of PSMD14 mRNA (92.98%), Log-rank χ2 were 26.070 and 43.060 respectively, both P<0.01. TNM stage Ⅲ+Ⅳ, low differentiation degree, lymph node metastasis, high expression of CYP1B1 mRNA and high expression of PSMD14 mRNA were independent risk factors for the survival prognosis of colorectal cancer patients (P<0.05). Conclusion CYP1B1 and PSMD14 mRNA are highly expressed in colorectal cancer tissue and are closely related to disease progression and survival prognosis. They have good diagnostic value for colorectal cancer, and may become important biomarkers for assessing treatment and prognosis in colorectal cancer patients.
