Abstract:

Objective To explore the value of multi-slice spiral computed tomography (MSCT) combined with serum serine protease 2 (PRSS2) and ephrin A1 (EFNA1) in diagnosing lymph node metastasis in patients with gastric cancer. Methods A total of 124 patients with gastric cancer who were admitted to Xi'an Gaoxin Hospital from February 2021 to August 2024 were selected as the research subjects. Among them, 74 were male and 50 were female; the age ranged from 34 to 73 (55.33±5.28) years old. All patients underwent MSCT examination, serum PRSS2 and EFNA1 tests, and pathological examination. Based on the pathological examination results, the patients were divided into the non-metastasis group (59 cases) and the metastasis group (65 cases). The parameters of MSCT [blood volume (BV), blood flow (BF), surface permeability (PS), and mean transit time of contrast agent (MTT)] were compared between the two groups, as well as serum PRSS2 and EFNA1. Independent sample t test, and Mann-Whitney U test were used for statistical analysis. The value of combining MSCT parameters with serum PRSS2 and EFNA1 in diagnosing lymph node metastasis in patients with gastric cancer was analyzed using the receiver operating characteristic curve (ROC). Results Comparison between the two groups of BV showed no statistically significant difference (P>0.05); in the metastasis group, BF, PS, and MTT were all higher than those in the non-metastasis group [(92.66±27.82) ml/(100 mg·min) vs. (73.42±20.86) ml/(100 mg·min), (9.64±2.78) ml/(100 mg·min) vs. (7.61±1.18) ml/(100 mg·min), (28.54±5.28) s vs. (22.67±3.14) s] (all P<0.05). The serum levels of PRSS2 and EFNA1 in the metastasis group were higher than those in the non-metastasis group [3.65 (2.87, 5.22) vs. 2.12 (1.82, 2.56), 1.63 (1.30, 1.77) vs. 1.15 (0.95, 1.32)] (both P<0.05). The ROC curve showed that the combination of MSCT parameters (BF, PS, MTT) and serum PRSS2, EFNA1 for diagnosing lymph node metastasis in gastric cancer patients had a higher sensitivity than single diagnosis, and the area under the curve was higher than that of single diagnosis (all P<0.05), while the specificity was basically consistent with that of single diagnosis. Conclusion The MSCT parameters (BF, PS, MTT) and serum PRSS2, EFNA1 are all helpful for the clinical diagnosis of lymph node metastasis in patients with gastric cancer, and their combined diagnosis has a higher value.

摘要:

目的 探讨多层螺旋计算机断层扫描(MSCT)联合血清丝氨酸蛋白酶2(PRSS2)、肝配蛋白A1(EFNA1)诊断胃癌患者淋巴结转移的价值。方法 选取2021年2月至2024年8月西安高新医院收治的124例胃癌患者作为研究对象,其中男74例,女50例;年龄34~73(55.33±5.28)岁。所有患者均行MSCT检查、血清PRSS2和EFNA1检测、病理检查。根据病理检查结果,将患者分为未转移组(59例)和转移组(65例)。比较两组MSCT参数[血容量(BV)、血流量(BF)、表面通透性(PS)、对比剂平均通过时间(MTT)]、血清PRSS2和EFNA1。采用独立样本t检验、Mann-Whitney U检验进行统计学分析。采用受试者操作特征曲线(ROC)分析MSCT参数联合血清PRSS2、EFNA1诊断胃癌患者淋巴结转移的价值。结果 两组BV比较,差异无统计学意义(P>0.05);转移组BF、PS、MTT均高于未转移组[(92.66±27.82)ml/(100 mg·min)比(73.42±20.86)ml/(100 mg·min)、(9.64±2.78)ml/(100 mg·min)比(7.61±1.18)ml/(100 mg·min)、(28.54±5.28)s比(22.67±3.14)s](均P<0.05)。转移组血清PRSS2、EFNA1均高于未转移组[3.65(2.87,5.22)比2.12(1.82,2.56)、1.63(1.30,1.77)比1.15(0.95,1.32)](均P<0.05)。ROC显示,MSCT参数(BF、PS、MTT)联合血清PRSS2、EFNA1诊断胃癌患者淋巴结转移的灵敏度高于单独诊断,曲线下面积高于单独诊断(均P<0.05),特异度与单独诊断基本一致。结论 MSCT参数(BF、PS、MTT)与血清PRSS2、EFNA1均有助于临床诊断胃癌患者淋巴结转移,且联合诊断价值更高。
