In many studies, regulatory T cell increase is seen both in patients with newly diagnosed multiple myeloma and post chemotherapy patients including autologous stem cell transplants. Multiple myeloma is a malignant plasma cell disease. Regulatory T cells have a role in immune homeostasis from cancer and inflamatory conditions to autoimmune diseases. PD-1 pathway stimulates T cell population towards regulatory T cell development. It has been shown that PDL1 plays an important role in differentiating inducable regulatory T cells. Recently, at least six clinical studies targeting PDL1 or PD-1 on multiple myeloma have been started. In accordance with the current literature, we suggest that patients with myeloma can benefit anti PD-1/PDL1 therapy.
