ANN SURG:肿瘤浸润中性粒细胞可作为胃癌的预后因素

2018-01-11 MedSci MedSci原创

肿瘤浸润中性粒细胞在多种肿瘤中存在,但是其在胃癌中的临床意义尚不清楚。ANN SURG近期发表了一篇文章,研究肿瘤浸润中性粒细胞的预后意义并建立预测模型对胃癌患者进行术后风险分层。

肿瘤浸润中性粒细胞在多种肿瘤中存在,但是其在胃癌中的临床意义尚不清楚。ANN SURG近期发表了一篇文章,研究肿瘤浸润中性粒细胞的预后意义并建立预测模型对胃癌患者进行术后风险分层。

研究纳入3个胃癌患者独立队列。作者通过免疫组化染色CD66b评估肿瘤浸润中性粒细胞情况,并分析其与临床病理特征和临床结局之间的关系。研究结果表明,在训练队列,测试队列和验证队列中,胃癌中的肿瘤浸润中性粒细胞分别为0-192/高倍视野(HPF),0-117/HPF和0-142/HPF。肿瘤浸润中性粒细胞与淋巴结分级和肿瘤分期负相关。多因素分析表明肿瘤浸润中性粒细胞和肿瘤淋巴结转移分期是总生存的独立预后因素。将肿瘤浸润中性粒细胞和TNM分期系统相结合建立预测模型对总生存的预测更为准确。更重要的是,肿瘤浸润中性粒细胞更多的患者术后辅助化疗获益更大,更有利于患者生存。这些结果在独立的测试队列和验证队列中均得到证实。

文章最后认为,胃癌肿瘤浸润中性粒细胞是独立的预后因素,可以与标准的TNM分期相结合进行风险分层并预测胃癌患者术后化疗获益及总生存。
