最近从合作医院那里收到这样一条信息。

尴尬不,这份清单涵盖了大家所熟知的主流水刊,哦不sorry,是期刊。

物极必反的道理大家都懂,这一现象推广到所有的医院也只是时间问题。当所有人都在庸庸碌碌做同样的事情的时候,当所有人都在解读3分数据挖掘文章的时候,我并不是说我们不看了,只是,眼光要放长远。




今天为大家带来一篇来自20分杂志JAMA Oncol的文章

JAMA OncologyIF=20.871)是一个来自北美的顶级期刊,审稿周期长(1-2个月),版费贵(3000美刀左右),自引率低,所有特点都符合牛逼杂志该有的气质。

Abstract

Importance  The prevalence of early-stage non–small cell lung cancer (NSCLC) is expected to increase with recent implementation of annual screening programs. Reliable prognostic biomarkers are needed to identify patients at a high risk for recurrence to guide adjuvant therapy.

Objective  To develop a robust, individualized immune signature that can estimate prognosis in patients with early-stage nonsquamous NSCLC.

Design, Setting, and Participants  This retrospective study analyzed the gene expression profiles of frozen tumor tissue samples from 19 public NSCLC cohorts, including 18 microarray data sets and 1 RNA-Seq data set for The Cancer Genome Atlas (TCGA) lung adenocarcinoma cohort. Only patients with nonsquamous NSCLC with clinical annotation were included. Samples were from 2414 patients with nonsquamous NSCLC, divided into a meta-training cohort (729 patients), meta-testing cohort (716 patients), and 3 independent validation cohorts (439, 323, and 207 patients). All patients underwent surgery with a negative surgical margin, received no adjuvant or neoadjuvant therapy, and had publicly available gene expression data and survival information. Data were collected from July 22 through September 8, 2016.

Main Outcomes and Measures  Overall survival.

Results  Of 2414 patients (1205 men [50%], 1111 women [46%], and 98 of unknown sex [4%]; median age [range], 64 [15-90] years), a prognostic immune signature of 25 gene pairs consisting of 40 unique genes was constructed using the meta-training data set. In the meta-testing and validation cohorts, the immune signature significantly stratified patients into high- vs low-risk groups in terms of overall survival across and within subpopulations with stage I, IA, IB, or II disease and remained as an independent prognostic factor in multivariate analyses (hazard ratio range, 1.72 [95% CI, 1.26-2.33; P < .001] to 2.36 [95% CI, 1.47-3.79; P < .001]) after adjusting for clinical and pathologic factors. Several biological processes, including chemotaxis, were enriched among genes in the immune signature. The percentage of neutrophil infiltration (5.6% vs 1.8%) and necrosis (4.6% vs 1.5%) was significantly higher in the high-risk immune group compared with the low-risk groups in TCGA data set (P < .003). The immune signature achieved a higher accuracy (mean concordance index [C-index], 0.64) than 2 commercialized multigene signatures (mean C-index, 0.53 and 0.61) for estimation of survival in comparable validation cohorts. When integrated with clinical characteristics such as age and stage, the composite clinical and immune signature showed improved prognostic accuracy in all validation data sets relative to molecular signatures alone (mean C-index, 0.70 vs 0.63) and another commercialized clinical-molecular signature (mean C-index, 0.68 vs 0.65).

Conclusions and Relevance  The proposed clinical-immune signature is a promising biomarker for estimating overall survival in nonsquamous NSCLC, including early-stage disease. Prospective studies are needed to test the clinical utility of the biomarker in individualized management of nonsquamous NSCLC.

      

背景介绍

NSCLC是美国和全世界癌症死亡的主要原因(占肺癌的85%)大多数早期 NSCLC患者目前在局部治疗后未接受辅助全身治疗,因为几项大型随机研究未能显示未选择患者的生存获益,对于这些患者,与化疗相关的毒性作用,可能超过许多人的潜在益处。

已有结果表明免疫系统的各种组分是癌症发生和发展期间的决定因素。逃避免疫破坏已被公认为癌症的新标志,例如细胞毒性淋巴细胞的肿瘤内浸润,

是与几种癌症类型(包括NSCLC)的更好预后相关。


本研究使用多个基因表达数据集,以开发和验证基于免疫相关基因对(IRGPs)的非鳞状的个体化预后特征。
