目的

探讨三级淋巴结构(TLS)在胃神经内分泌肿瘤(g-NEN)中的特点及预后价值并构建和验证预后列线图模型。

方法

回顾性收集2013年1月~2021年12月确诊为g-NEN 140例临床资料。通过HE染色及免疫组化分析TLS,采用SPSS22.0软件经单因素和多因素Cox回归分析确定生存独立预后影响因素,用R软件(R version 4.1.0)绘制列线图模型和验证列线图模型。

结果

患者年龄中位数是62.5 (51, 69.25)岁;男84例(60%),女56例(40%);TLS密度中位数是0.0694个/mm2(0.01585, 0.19775);WHO分类为g-NET 64例(45.7%),g-NEC/g-MiNEN 76例(54.3%);TNM分期Ⅰ/Ⅱ80例(57.1%),Ⅲ/Ⅳ 60例(42.9%),血管侵犯56例(40%),神经侵犯47例(33.6%)。TLS主要位于肿瘤边缘或肿瘤间质区域,有三种不同的成熟形态。TLS密度、WHO分类、TNM分期是独立预后影响因素(P<0.05)。列线图模型区分度、校准度、临床实用性高。

结论

TLS密度是g-NEN预后独立影响因素,纳入了TLS的列线图模型具有良好的预测性能和临床应用价值。

Objective

To investigate the characteristics and prognostic value of tertiary lymphoid structures (TLS) in gastric neuroendocrine neoplasms (g-NEN) and to construct and validate a prognostic nomogram.

Methods

We retrospectively collected the clinical data from 140 patients with g-NEN at Nanjing Drum Tower Hospital from 2013 to 2021. We firstly analyzed the characteristics of TLS by HE&immunohistochemical staining and then univariate and multivariate Cox analysis using SPSS 22.0 software was performed to derive independent risk factors; Lastly, we constructed a nomogram and validated its efficacy by using R studio.

Results

The median age of the 140 g-NEN patients was 62.5 (51, 69.25) years; 84 (60%) were male and 56 (40%) were female; the median of TLS density was 0.0694 cells per mm2 (0.01585, 0.19775); 64 (45.7%) were g-NET, 76 (54.3%) were g-NEC/g-MiNEN; TNM stage Ⅰ/Ⅱ was 80 (57.1%), 60 (42.9%) was Ⅲ/Ⅳ, vascular invasion was 56 (40%), and neurological invasion was 47 (33.6%). TLS were mainly located in the tumor margin or stroma region and have three different mature shapes. TLS density, WHO classification and TNM stage were independent prognostic factors (P<0.05). The nomogram has high degree of discrimination, calibration and clinical practicability.

Conclusion

The TLS density is an independent prognostic factor of g-NEN and the nomogram incorporating TLS density has good predictive performance and clinical application.
