ISABEL-VON-DER DECKEN is an academic who published a paper in 2021 entitled Changes in the Tumor Immune Microenvironment during Disease Progression in Patients with Ovarian Can. ISABEL-VON-DER DECKEN published this work as part of a team: Westergaard, Marie Christine Wulff. Here is a description of this work: Anti-PD1/PDL1 therapy has proven efficacious against many cancers but only reached modest objective response rates against recurrent ovarian cancer. A deeper understanding of the tumor microenvironment (TME) may reveal other immunosuppressive mechanisms that warrant investigation as immunotherapeutic targets for this challenging disease. Matched primary and recurrent tumors from patients with high-grade serous ovarian carcinoma (HGSC) were analyzed by multicolor immunohistochemistry/immunofluorescence for the presence of T cells, B cells, macrophages, and for the expression of immunosuppressive and HLA molecules. Cancer- and immune-related gene expression was assessed by NanoString analysis. Recurrent tumors showed increased infiltration by immune cells, displayed higher expression of PDL1, I.
