MKI67 and neoplasm: Total cytokine/chemokine array, immune cells assay (CyTOF), circulating tumor cells/circulating tumor DNA (ctDNA), targeted next-generation sequencing (NGS), and viral replication will be measured from liquid biopsies while tumor-infiltrating lymphocytes, tumor growth (Ki67 assay), and the replication of viral particles (electron microscopy) will be assessed in tumors.
