Programmed Death-Ligand (PD-L1) Automated Image Analysis Programmed Death-Ligand 1 expression is an important cancer biomarker and has become a critical par t of patient management for immunotherapy. The targeted blockade of PD-L1 may help to restore the antitumor response. Development of the combined positive score (CPS) for the evaluation of PD-L1 in solid tumors has indicated that PD-L1 expression on both tumor and tumor-associated immune cells is associated with clinical outcome.
OptraSCAN's Solution for Immuno-oncology Optra PD-L1 automated image analysis for research use, supports interpretation of PD-L1 IHC expression on both tumor and immune cells in solid tumors. It determines PD-L1 expression on tumor and immune cells showing partial or complete membrane staining on tumor cells alongwith membrane and/or cytoplasmic staining on immune cells in a single read. It is reliable and can be used to assess PD- L1 expression in a more objective manner.
General considerations by the PD-L1 assay Ø Fully automated algorithm evaluates and generates scores for both, regions of interest and whole slide analysis with
minimal human intervention Ø Score generation based on the number of PD-L1 positive cells (tumor, lymphocytes and macrophages) in relation to total
tumor cells allows capturing of tumor and immune cells in a single read Ø Fully integrated image acquisition and automated evaluation of tumor area using Computer aided region detection system
based on Artificial Neural Network Ø Reporting module included with case management
The following analytical components are assessed by the AI tool m Tumor Cell staining (an estimate of the percentage of tumor cells exhibiting partial or complete membranous staining) m Immune Cell (IC) staining (an estimate of the percentage of ICs, including macrophages and lymphocytes, within the
tumor, exhibiting staining).
