摘要:

目的 探讨丝氨酸/苏氨酸蛋白激酶1(AKT1)、异分支酸酶包含域1(ISOC1)在胃癌组织表达及诊断效能分析。 方法 选取2023年3月至2024年9月于沧州市人民医院诊治的90例胃癌患者作为研究对象,比较癌组织与癌旁组织AKT1、ISOC1阳性表达率及阳性评分;比较不同特征胃癌患者癌组织AKT1、ISOC1阳性评分;采用Spearman法分析癌组织中AKT1、ISOC1表达与胃癌患者临床特征的相关性;采用logistic回归模型构建AKT1联合ISOC1诊断胃癌的模型;采用ROC曲线分析AKT1、ISOC1及两项联合诊断胃癌的效能。 结果 癌组织中AKT1、ISOC1阳性表达率、阳性评分高于癌旁组织(P < 0.05)。不同分化程度、临床分期、浸润深度及有无淋巴结转移、远处转移的癌组织AKT1、ISOC1比较,差异有统计学意义(P < 0.05)。Spearman相关性分析显示,AKT1、ISOC1与分化程度、临床分期、淋巴结转移、浸润程度、远处转移呈正相关(P < 0.05)。AKT1、ISOC1及两项联合诊断胃癌的AUC值分别为0.735、0.726、0.875,(P < 0.05);敏感度分别为60.00%、56.70%、75.60%;特异度分别为85.60%、83.30%、87.80%;AKT1联合ISOC1诊断胃癌的AUC值高于AKT1、ISOC1单独诊断(Z = -3.003、-3.196,P < 0.05)。 结论 在胃癌组织中AKT1、ISOC1呈高表达趋势,且其表达会随病情进展而上调,联合检测其表达水平对诊断胃癌和评估预后具有重要意义。

Abstract:

Objective To explore the expression of serine/threonine protein kinase 1 (AKT1) and Isochorismatase Domain-Containing 1 (ISOC1) in gastric cancer tissues and evaluate their diagnostic utility. Methods A total of 90 patients with gastric cancer who were diagnosed and treated in our hospital between March 2023 and September 2024 were recruited as the study subjects. The positive expression rates and positive scores of AKT1 and ISOC1 in cancer tissues and adjacent tissues were compared. The AKT1 and ISOC1 positive scores of gastric cancer patients with diverse characteristics were also compared. The Spearman correlation analysis was employed to examine the relationship between the expression of AKT1 and ISOC1 in cancer tissues and the clinical features of gastric cancer patients. A diagnostic model for gastric cancer, integrating AKT1 and ISOC1, was established using the Logistic regression model. Receiver operating characteristic (ROC) curves were plotted to analyze the area under the curve (AUC) value, sensitivity, and specificity of AKT1, ISOC1, and their combined diagnosis for gastric cancer. Results The positive expression rates and positive scores of AKT1 and ISOC1 in cancer tissues were significantly higher than those in paracancerous tissues (P < 0.05). In gastric cancer patients, the expressions of AKT1 and ISOC1 were notably higher in patients with low differentiation, clinical stage Ⅰ~Ⅱ, invasion depth T1-2, absence of lymph node metastasis, and no distant metastasis compared to those with moderate differentiation, clinical stage Ⅲ~Ⅳ, invasion depth T3-4, and presence of lymph node metastasis and distant metastasis (P < 0.05). Spearman's correlation analysis indicated that AKT1 and ISOC1 were positively correlated with the degree of differentiation, clinical stage, lymph node metastasis, invasion degree, and distant metastasis (P < 0.05). The area under the curve (AUC) values of AKT1, ISOC1, and their combined diagnosis for gastric cancer were 0.735, 0.726, and 0.875 respectively (P < 0.05). The sensitivities were 60.00%, 56.70%, and 75.60%, while the specificities were 85.60%, 83.30%, and 87.80%. The AUC value of the combined detection of AKT1 and ISOC1 in the diagnosis of gastric cancer was higher than that of AKT1 or ISOC1 alone (Z = -3.003, -3.196, P < 0.05). Conclusions AKT1 and ISOC1 are highly expressed in gastric cancer tissues, and their expressions are upregulated with the progression of the disease. The combined detection of their expression levels holds great significance for the diagnosis and prognosis assessment of gastric cancer.
