Abstract
Background
Microsatellite instability high (MSI-H) is an approved tissue-agnostic predictive biomarker of benefit to immune checkpoint inhibitors (ICI). However not all patients (pts) respond to ICI and additional biomarker of response in this population is still required. The Lung-Immune Prognostic Index (LIPI), combining derived NLR (dNLR=neutrophils/[leucocytes-neutrophils]) and lactate dehydrogenase (LDH) demonstrated a strong correlation with ICI outcomes in NSCLC and other tumor types. We aimed to evaluate the value of pretreatment LIPI for predicting benefit to ICI in MSI-H population.
Methods
We performed a multicenter retrospective study of pts with metastatic MSI-H tumors treated with ICI from Apr 2014 to May 2019. Biological and clinical data were retrospectively collected and LIPI was calculated based as previously reported. LIPI groups were: good (dNLR≤3 + LDH≤upper limit of normality [ULN]), intermediate (dNLR>3 or LDH>ULN and poor (dNLR>3+LDH>ULN). The primary endpoint was progression-free survival (PFS) and secondary endpoints were overall survival (OS), overall response rate (ORR).
Results
Preliminary data is available for 111 pts, with the following characteristics: 43 (39%) male; median age of 62 (24-93), median number of previous lines 1 (range 0 – 6); most common tumor types were colorectal (43%) and endometrial cancer (15%). MSI was defined by immunochemistry and/or polymerase chain reaction (PCR) in 88% and 37 pts (38%) had a confirmed Lynch Syndrome. 98 pts (88%) were treated with a single agent-PD(L)1 inhibitor. The median (m) PFS was 14.1 months (m.) [95%CI, 8.38-not reached (NR)] and the mOS was NR [95%CI, 30-xx] with 44% of ORR. LIPI stratified the population in: good (51, 46%), intermediate (50, 45%) and poor groups (10, 9%). The good group had mPFS of 20.9m. vs. 32m. for intermediate vs. 1.8m. for poor groups (P = 0.0006). In the good group, the ORR was 55% vs. 38% for intermediate vs. 13% in poor group (P = 0.05). OS data are not mature yet.
Conclusion
Poor LIPI is correlated with worse ICI outcomes (PFS, ORR) in MSI-H pts, identifying potentially a MSI-H subset of pts with no benefit from ICI. This study is still ongoing for assessing the value of LIPI in a larger cohort.

54P LIPI评分对接受免疫检查点抑制剂治疗的转移性微卫星不稳定性高癌症患者的适用性

抽象的
背景
高微卫星不稳定性(MSI-H)是公认的对免疫检查点抑制剂(ICI)有益的组织不可知的预测生物标志物。但是,并非所有患者(pts)都对ICI有反应,并且在该人群中仍需要其他反应生物标志物。合并衍生的NLR(dNLR =中性粒细胞/ [白细胞-中性粒细胞])和乳酸脱氢酶(LDH)的肺部免疫预后指数(LIPI)与NSCLC和其他肿瘤类型的ICI预后密切相关。我们旨在评估LIPI预处理对预测MSI-H人群ICI获益的价值。
方法
我们对2014年4月至2019年5月接受ICI治疗的转移性MSI-H肿瘤患者的pts进行了多中心回顾性研究。回顾性收集生物学和临床数据,并根据先前报道计算LIPI。LIPI组为:良好(dNLR≤3+LDH≤正常值上限[ULN]),中度(dNLR> 3或LDH> ULN)和较差(dNLR> 3 + LDH> ULN),主要终点为无进展生存期(PFS)和次要终点为总生存期(OS),总缓解率(ORR)。
结果
有111点的初步数据,其具有以下特征:43(39%)男性;中位数年龄为62岁(24-93),前几行的中位数为1(范围为0-6);最常见的肿瘤类型是大肠癌(43%)和子宫内膜癌(15%)。MSI是通过免疫化学和/或聚合酶链反应(PCR)定义的,其中88%和37 pts(38%)患有林奇综合征。用单药-PD(L)1抑制剂治疗了98分(88%)。PFS中位数(m)为14.1个月(m。)[95%CI,未达到8.38(NR)],mOS为NR [95%CI,30-xx],ORR为44%。LIPI将人群分为以下几类:好(51%,46%),中(50%,45%)和穷人(10%,9%)。好组的mPFS为20.9m。与32m。中级vs. 1.8m。对于贫困群体(P = 0.0006)。良好组的ORR为55%,中级组的ORR为38%,而贫困组的ORR为13%(P = 0.05)。
结论
LIPI差与MSI-H患者的ICI预后差(PFS,ORR)相关,从而可能从MCI-H患者中识别出MSI-H患者的子集而无从ICI中获益。这项研究仍在进行中,以评估较大规模人群中LIPI的价值。
