Purpose Although programmed death (PD)-1 pathway inhibitors are now used in nearly all patients with advanced non-small-cell lung cancer (NSCLC), the large number of NSCLC and concurrent autoimmune disease (AID) have been universally excluded from immunotherapy clinical trials. Therefore, safety PD-1 PD-ligand 1 (PD-L1) underlying AID is currently unknown. Methods As part a multi-institutional effort, we retrospectively collected clinicopathologic data history who received monotherapy either...

BackgroundIn non-small-cell lung cancers with programmed death-ligand 1 (PD-L1) expression on ≥50% of tumor cells, first-line treatment the PD-1 inhibitor pembrolizumab improves survival compared platinum-doublet chemotherapy. Whether higher PD-L1 levels within range 50%–100% predict for even greater benefit to is currently unknown.Patients and methodsIn this multicenter retrospective analysis, we analyzed impact overall response rate (ORR), median progression-free (mPFS), (mOS) in patients...

Programmed cell death protein 1 inhibitors increasingly are being used to treat patients with advanced lung carcinomas. death-ligand (PD-L1) immunohistochemistry (IHC) in tumor cells (TCs) and tumor-infiltrating immune (ICs) is select for programmed inhibition, but few studies have evaluated PD-L1 IHC cytology specimens. The objective of the current study was compare blocks matched surgical specimens.A total 56 specimens obtained between 2013 2016 matching were stained anti-PD-L1. Membranous...

Clinically-available biomarkers to identify the fraction of patients with small cell lung cancer (SCLC) who respond immune-checkpoint inhibitors (ICIs) are lacking. High nonsynonymous tumor mutational burden (TMB), as assessed by whole exome sequencing, correlates improved clinical outcomes for SCLC treated ICIs. Whether TMB targeted next generation sequencing (NGS) is associated efficacy ICIs in currently unknown. Here we determined whether NGS SCLC.We collected clinicopathologic data from...

8511 Background: Dramatic responses to MET inhibitors have been reported in patients with NSCLC harboring activating mutations that cause exon 14 ( METdel14) skipping. We conducted a multicenter retrospective analysis of pts METdel14 determine if treatment impacts survival. Methods: collected clinicopathologic data on NSCLC. Event-time distributions were estimated using Kaplan-Meier and compared the log-rank test. Multivariable Cox models fitted estimate hazard ratios. Results: Of 148 mutant...

Abstract Mohs micrographic surgery (MMS) is considered the gold standard for treating high-risk cutaneous basal cell carcinoma (BCC), but expensive, time-consuming, and can be unpredictable as to how many stages will required or large final lesion corresponding surgical defect be. This study meant investigate whether optical coherence tomography (OCT), a highly researched modality in dermatology, used preoperatively map out borders of BCC, resulting fewer MMS smaller defect. In this...

We pursued genomic analysis of an exceptional responder with non-small cell lung cancer (NSCLC) through a multi-platform effort to discover novel oncogenic targets.In this open-label, single-arm phase II study (NCT01829217), enriched cohort patients advanced NSCLC was treated the multi-kinase inhibitor sunitinib. The primary endpoint objective response rate. Tissue collected for responders, and candidate oncogene validated using in vitro models edited by CRISPR-Cas9.Of 13 enrolled, 1 patient...

Purpose Genomic profiling for personalized targeted therapy has become standard of care. We report the success genomic non–small cell lung cancer (NSCLC) obtained by trans‐thoracic needle biopsy (TTNB) in a single center experience. Materials and Methods Patients with NSCLC who underwent TTNB were identified. Pathology specimens evaluated tumor adequacy then analyzed selected exons epidermal growth factor receptor, KRAS, BRAF, PIK3CA, ERBB2. ALK rearrangements detected fluorescence situ...

9037 Background: Among patients with NSCLC and a PD-L1 TPS ≥50%, the response rate to PD-1 inhibitor pembrolizumab is ~45%. Whether certain subsets of ≥50% are more likely benefit from treatment currently unknown. We compared outcomes among treated first-line inhibitors different groupings: 50-74% vs 75-100%. Methods: retrospectively analyzed who received as for Dana-Farber Cancer Institute Memorial Sloan Kettering Center. Clinicopathologic characteristics clinical were Event-time...

Background Magnetic Resonance Imaging (MRI) relies on optimal scanning parameters to achieve maximal signal-to-noise ratio (SNR) and high contrast-to-noise (CNR) between tissues resulting in quality images. The optimization of such is often laborious, time consuming, user-dependent, making harmonization imaging a difficult task. In this report, we aim develop validate computer simulation technique that can reliably provide “optimal vivo parameters” ready be used for evaluation disease...
