To molecularly characterize the rare and aggressive tumors known as angiosarcomas, Chan et al utilized a combination of transcriptomic immuno-oncology profiling with multiplex immunohistochemistry and immunofluorescence. HALO image analysis software was used for the quantification of PD-L1, CD68, CD8, FOXP3, CD15, and ERG. From these studies, three phenotypes of patients were identified according to etiology, anatomical origin, signaling pathways, and the tumor inflammation signature. These distinct biological phenotypes...
