In this week’s episode, we will review a study describing real-world data where PET scans following chemotherapy for primary mediastinal B-cell lymphoma were used to guide consolidative radiotherapy, learn more about the novel role of the BLOC-2 protein complex in the formation of Weibel-Palade bodies that store von Willebrand Factor in endothelial cells, and finally, examine how mutant TP53 in myelodysplastic syndrome is associated with immune checkpoint overexpression in the bone marrow.
