    Abstract: The present invention relates to a biomarker composition for predicting the prognosis of cancer malignancy induced by exposure to microplastics and use thereof, and more particularly, it was confirmed that the expression level of CD44, E-cadherin, N-cadherin, PD-L1, NPAS2, NR1D1, DNMT1, SLC7A2, PCDH7 and CLDN7 was changed in cancer cell lines and animal models treated with polystyrene microspheres which are the one type of microplastic for 4 weeks, and malignancy was induced due to an increase in proliferation, migration and invasion of cancer cells by the change in the expression level of the gene, and 5-year overall survival rates in gastric cancer patients decreased and thus the genes may be provided as a biomarker composition for predicting the prognosis of cancer malignancies by exposure to microplastics.

    Abstract: Immune context scores are calculated for tumor tissue samples using continuous scoring functions. Feature metrics for at least one immune cell marker are calculated for a region or regions of interest, the feature metrics including at least a quantitative measure of human CD3 or total lymphocyte counts. A continuous scoring function is then applied to a feature vector including the feature metric and at least one additional metric related to an immunological biomarker, the output of which is an immune context score. The immune context score may then be plotted as a function of a diagnostic or treatment metric, such as a prognostic metric (e.g. overall survival, disease-specific survival, progression-free survival) or a predictive metric (e.g. likelihood of response to a particular treatment course). The immune context score may then be incorporated into diagnostic and/or treatment decisions.
