Ann Oncol:中国建立NSCLC术后高危脑转移风险的预测数学模型

2015-02-01 CMT 中国医学论坛报

中山大学附属肿瘤医院王思愚教授的团队近期在《肿瘤学年鉴》(Ann Oncol)上发文称,预防性脑照射(PCI)可有效降低高危ⅢA-N2期非小细胞肺癌(NSCLC)的脑转移风险。 在这项研究的整体设计中,有一个非常关键的筛选条件——高危。据王教授介绍,这也是源自他之前的一项研究,其发表于《肺癌》杂志 (Lung Cancer 2009, 64: 238)。在文章中,作者阐述了如何利用数学模型

中山大学附属肿瘤医院王思愚教授的团队近期在《肿瘤学年鉴》(Ann Oncol)上发文称,预防性脑照射(PCI)可有效降低高危ⅢA-N2期非小细胞肺癌(NSCLC)的脑转移风险。

在这项研究的整体设计中,有一个非常关键的筛选条件——高危。据王教授介绍,这也是源自他之前的一项研究,其发表于《肺癌》杂志 (Lung Cancer 2009, 64: 238)。在文章中,作者阐述了如何利用数学模型来筛选术后高危脑转移风险的人群。具体计算公式如下。

局部晚期非小细胞肺癌术后高危脑转移风险预测数学模型

Logit (p)=8.215−0.903×(纵隔淋巴结阳性数)−0.872×(手术性质)−0.714×(病理类型)−1.893×(纵隔淋巴结转移程度)−0.948×(病理分期)−1.034×(术后是否化疗)。

P=1-p

P≥ 0.44 预测脑转移高危

数学模型赋值

1)纵隔淋巴结阳性数若少于 4 个分数为 1,4-6 个分数为 2,超过6 个分数为 3;

2)手术性质若完全切除分数为 1,不完全切除分数为 2;

3)病理类型若鳞癌分数为 1,非鳞癌分数为 2;

4)纵隔淋巴结转移程度若单区域转移(L1)分数为 1,两个区域转移(L2)分数为 2,三个区域转移(L3)分数为 3 (纵隔淋巴结分为 3 区:①上区:包括最上纵隔、气管旁、血管前、气管后和气管支气管拐角淋巴结;②主动脉区:包括主动脉窗及主动脉旁淋巴结;③下区:包括隆凸下、食管旁和下 肺韧带淋巴结);

5)病理分期若 ⅢA 期分数为 1,ⅢB 期分数为 2;

6)术后是否化疗若未接受术后辅助化疗分数为 0,接受了术后辅助化疗分数为 1。
