摘要:

目的 分析结直肠癌(CRC)患者术后化疗期卷曲蛋白6(FZD6)mRNA表达的动态变化及其对预后的预测价值。方法 选取2022年8月—2024年4月南京江北医院行化疗的CRC患者130例,化疗结束后根据预后情况分为预后良好组(89例)和预后不良组(41例)。收集所有患者的临床资料,并检测FZD6 mRNA相对表达量。采用多因素Logistic回归分析评价CRC患者预后不良的影响因素,采用Cox回归分析评估不同临床病理特征下FZD6 mRNA表达与CRC患者预后的关系。采用多元线性回归分析评估FZD6 mRNA表达与免疫因子水平的关系。采用受试者工作特征(ROC)曲线和限制性立方样条模型分析FZD6 mRNA表达与预后结局的相关性。采用Kaplan-Meier生存曲线分析CRC患者的生存情况。结果 与预后良好组比较,预后不良组肿瘤≥5 cm肿瘤浸润深度T3~T4、TNM分期Ⅲ~Ⅳ期、淋巴转移、脉管浸润和神经浸润所占比例显著升高(P<0.05),CD4+T细胞、CD8+T细胞、CD158a、CD94、NKG2D、NKp30、NKp46、IL-2、TNF-α水平均显著降低(P<0.05)。预后不良组化疗6个月FZD6 mRNA相对表达量高于预后良好组(P<0.05),2个组之间化疗前和化疗1、3个月FZD6 mRNA相对表达量差异均无统计学意义(P>0.05)。FZD6 mRNA相对表达量升高是CRC患者预后不良的危险因素(P<0.05),且肿瘤浸润深度、TNM分期、淋巴转移、脉管浸润和神经浸润均不影响两者之间的关系(P>0.05)。FZD6 mRNA与CD4+T细胞、CD8+T细胞、CD158a、CD94、NKG2D、NKp30、NKp46、IL-2、TNF-α呈负相关(P<0.05)。FZD6 mRNA判断CRC患者预后不良的AUC为0.927;当FZD6 mRNA>3.09时,CRC患者预后不良风险显著升高。FZD6 mRNA低表达组1年生存率为61.43%,显著高于高表达组(28.33%)(Log-rank χ2=8.565,P<0.001)。结论 FZD6 mRNA高表达与CRC患者化疗后预后不良密切相关,或可作为CRC患者预后评估的生物标志物。

Abstract:

Objective To analyze the dynamic changes of frizzled-6(FZD6) mRNA expression during postoperative chemotherapy in patients with colorectal cancer(CRC) and its predictive value for prognosis. Methods A total of 130 CRC patients who received chemotherapy at Nanjing Jiangbei Hospital from August 2022 to April 2024 were enrolled. They were classified into good prognosis group(89 cases) and poor prognosis group(41 cases) based on their prognosis. The clinical data were collected,and the relative expression level of FZD6 mRNA was determined. Multivariate Logistic regression analysis was used to evaluate the influencing factors of prognosis in CRC patients,and the relationship between FZD6 mRNA expression and prognosis under different clinicopathological characteristics was further analyzed. Multivariate linear regression analysis was used to determine the relationship between FZD6 mRNA expression and immune factor levels. Receiver operating characteristic(ROC) curve and restricted cubic spline model were used to analyze the correlation between FZD6 mRNA expression and prognosis outcomes. Kaplan-Meier survival curve was used to analyze the impact of FZD6 mRNA expression on the survival of CRC patients. Results Compared with good prognosis group,poor prognosis group had higher proportions of tumor size ≥5 cm tumor invasion depth T3-T4,advanced TNM stageⅢ-Ⅳ,lymphatic metastasis,vascular invasion and nerve invasion(P<0.05). The levels of CD4+T,CD8+T,CD158a,CD94,NKG2D,NKp30,NKp46,IL-2 and TNF-α were lower(P<0.05). Compared with good prognosis group after 6 months of chemotherapy,the FZD6 mRNA expression in poor prognosis group was increased(P<0.05). There was no statistical significance in the relative expression signifioance levels of FZD6 mRNA between the 2 groups before chemstherapy and 1 and 3 months after chemoterapy (P>0.05). FZD6 mRNA relative expression level was a risk factor for poor prognosis in CRC patients(P<0.05),and tumor invasion depth,TNM stage,lymphatic metastasis,vascular invasion and nerve invasion did not affect the relationship(P>0.05). FZD6 mRNA was negatively correlated with CD4+T,CD8+T,CD158a,CD94,NKG2D,NKp30,NKp46,IL-2 and TNF-α(P<0.05). The area under curve(AUC) of FZD6 mRNA in judging the poor prognosis of CRC patients was 0.927,and the risk of poor prognosis in CRC patients was increased when FZD6 mRNA was >3.09. The 1-year survival rate of patients with low FZD6 mRNA expression(61.43%) was higher than that of patients with high FZD6 mRNA expression(28.33%)(Long-rank χ2=8.565,P<0.05). Conclusions FZD6 mRNA expression during postoperative chemotherapy in CRC patients is an independent risk factor for poor prognosis,and it is negatively correlated with immune factor levels and positively correlated with the risk of poor prognosis.
