Description: This study is a follow-on to one of the GeoMx DSP papers published in Nature Medicine by Dr. Jennifer Wargo (Nat Med. 2018 Nov;24(11)). The new study builds on observations of the original work to further investigate the role of T cells, B cells and tertiary lymphoid structures in metastatic melanoma. It leveraged rare cell profiling and a 60+ plex protein panel to characterize immune changes associated with neoadjuvant immunotherapy.

Title: Combinatorial strategies for tissue characterization with advanced image analysis and digital spatial profiling

Lead author: Raffaele De Filippis, Ph.D., University of St. Andrews, St. Andrews, United Kingdom

Date/Time: Monday, April 1, 8:00am – 12:00pm ET

Spatial profiling of immune protein targets revealed a number of targets (PDL1, LAG3 and B7-H3) associated with HIF1a and not HIF2a.  This association explains poor outcome associated with patients with high HIF1a expression level and suggests potential immuno-therapy strategies that are distinct from patients with HIF2a.

Title: High density of CD68+HLA-DR- macrophages in the stroma of primary melanoma correlates with an unfavorable immune microenvironment as assessed by Digital Spatial Profiling with clinical outcome analysis

Lead author: Emanuelle M. Rizk, B.A., Columbia University, NY, NY, USA

Date/Time: Tuesday, April 2, 8:00am – 12:00pm ET

Abstract #: 2798, section 3

Description: This study highlights the importance of measuring expression levels in tissue compartments rather than in bulk to tease out subtle changes in the tumor microenvironment. Here spatial protein profiling was performed in compartments with high macrophage density.  Differential expression was observed in high macrophage comparments in close proximity to cytotoxic lymphocytes which was predictive of poor prognosis. This study highlights the importance of studying the location of macrophages within the tumor microenvironment.

Title: Profiling Plasma cell-free RNA (cfRNA) with the NanoString Low Input nCounter Assay

Lead Author: Chung-Ying (Alan) Huang, Ph.D., NanoString Technologies, Seattle, WA, USA

Date/Time:  Sunday, March 31, 1:00pm – 5:00pm ET

Abstract # / Section:  406 / 17

Description:  Circulating cell-free RNA (cfRNA) from blood is an attractive target for liquid biopsy based diagnostics because it offers the opportunity to transcriptionally characterize tumors without a tissue biopsy, but it is a challenging substrate due to low abundance and degradation. NanoString has developed a target enrichment strategy that permits characterization of cfRNA with any nCounter gene expression panel. This methodology poster benchmarks the technique against qPCR and demonstrates the ability to discriminate cfRNA from healthy donor, non-small cell lung cancer, and colorectal cancer.
