目的

探讨胃癌患者脾门淋巴结转移危险因素。

方法

回顾性分析2020年1月至2022年1月150例胃上部癌患者临床资料。使用免疫组织化学方法检测淋巴结转移或微转移。采用SPSS 20.0软件进行数据分析,计量资料用()表示,采用独立样本t检验;计数资料用频数表示,采用χ2检验;用多因素Logistic回归分别分析影响脾门淋巴结转移、微转移及总体转移的独立因素;采用EmpowerStats软件中的分层交互检验作用分析性别对独立因素与脾门淋巴结转移关系的影响作用;基于筛选的重要影响因素构建脾门淋巴结转移的结构方程模型并进行分析和检验。P<0.05为差异有统计学意义。

结果

150例患者中,33例患者脾门淋巴结转移,转移率为22.0 %(33/150),常规病理阴性的117例患者中有38例有脾门淋巴结微转移,转移率为32.5 %(38/117)。总体转移率为47.3%(71/150)。肿瘤横向部位、Bormann分型、No.4sa淋巴结转移、TNM分期、浸润深度、No.2淋巴结转移、No.4sb淋巴结转移是脾门淋巴结总体转移的独立影响因素(P<0.05)。进一步基于以上高危因素构建影响淋巴结总体转移的结构方程模型,可有效反映各研究变量与淋巴结总体转移的关系。验证模型具有较好的区分度、准确度。

结论

大弯侧、No.4sa淋巴结转移、Bormann分型Ⅲ-Ⅳ型、No.4sb淋巴结转移、黏膜下层浸润、Ⅲ-Ⅳ期、No.2淋巴结转移是脾门淋巴结总体转移的独立因素。本研究构建的影响淋巴结总体转移的结构方程模型整体适配情况较优,且验证模型具有较好的区分度、准确度。

Objective

To investigate the risk factors of splenic hilar lymph node metastasis in patients with gastric cancer.

Methods

The clinical data of 150 patients with upper gastric cancer from January 2020 to January 2022 were retrospectively analyzed. Lymph node metastases or micrometastases were detected by immunohistochemical methods. SPSS 20.0 was used for data analysis. Measurement data were expressed as () and independent sample t test was used. The counting data were expressed by frequency and χ2 test was used. Multivariate Logistic regression was used to analyze the independent factors affecting hilar lymph node metastasis, micrometastasis and total metastasis. The influence of gender on the relationship between independent factors and hilar lymph node metastasis was analyzed using the layered interaction test in Empower Stats software. The structural equation model of hilar lymph node metastasis was constructed based on the important factors of screening and analyzed and tested. P<0.05 was considered statistically significant.

Results

Among the 150 patients, 33 patients had hilar lymph node metastasis, with a metastasis rate of 22.0% (33/150). Among the 117 patients with negative routine pathology, 38 patients had hilar lymph node micrometastasis, with a metastasis rate of 32.5% (38/117). The overall transfer rate was 47.3% (71/150). Transverse location of tumor, Bormann classification, No.4sa lymph node metastasis, TNM stage, depth of invasion, No.2 lymph node metastasis and No.4sb lymph node metastasis were independent factors of total hilar lymph node metastasis (P<0.05). Based on the above risk factors, the structural equation model affecting the overall lymph node metastasis was further constructed, which could effectively reflect the relationship between the study variables and the overall lymph node metastasis. The verification model has good differentiation and accuracy.

Conclusion

Major curved side, No.4sa lymph node metastasis, Bormann classification Ⅲ-Ⅳ, No.4sb lymph node metastasis, submucosal infiltration, Ⅲ-Ⅳ stage, No.2 lymph node metastasis were independent factors of total hilar lymph node metastasis. In this study, the structural equation model established to affect the overall lymph node metastasis has a good overall fit, and the verified model has a good degree of differentiation and accuracy.
