چکیده

The T-cell lymphoproliferative disorders are a heterogeneous group of non-Hodgkin's lymphomas (NHL) for which current therapeutic strategies are inadequate, as most patients afflicted with these NHL will succumb to disease progression within 2 years of diagnosis. Appreciation of the genetic and immunologic landscape of these aggressive NHL, including PD-L1 (B7-H1, CD274) expression by malignant T cells and within the tumor microenvironment, provides a strong rationale for therapeutic targeting this immune checkpoint. While further studies are needed, the available data suggests that responses with PD-1 checkpoint blockade alone will unlikely approach those achieved in other lymphoproliferative disorders. Herein, we review the unique challenges posed by the T-cell lymphoproliferative disorders and discuss potential strategies to optimize checkpoint blockade in these T-cell derived malignancies.

Aplastic anemia evolving to myelodysplastic syndrome and later to a lymphoproliferative malignancy in a treated case of carcinoma breast: A case report emphasizing the importance of PET-CT in cutaneous T cell lymphoma

Although aplastic anemia (AA) and myelodysplastic syndrome (MDS) are separate entities with different management, distinction between the two can be difficult on morphological basis due to hypocellularity of bone marrow. MDS is one of the serious complications of AA. Karyotyping is definitive in the diagnosis of MDS. Better and robust investigations like 18F-Fluoro-deoxy-Glucose Posi...

PD-1 Blockade Promotes Emerging Checkpoint Inhibitors in Enhancing T Cell Responses to Allogeneic Dendritic Cells

Immune checkpoint inhibitors, which target coinhibitory T cell molecules to promote anticancer immune responses, are on the rise to become a new pillar of cancer therapy. However, current immune checkpoint-based therapies are successful only in a subset of patients and acquired resistances pose additional challenges. Finding new targets and combining checkpoint inhibitors might help to overcome...

Dendritic Cell Immunotherapy, the Next Step in Cancer Treatment

Cancer immunotherapy has gained a lot of interest over the past few years due to the success of immune checkpoint inhibitors in treating cancer (1, 2). Immune checkpoint inhibitors, such as monoclonal antibodies against cytotoxic T-lymphocyte–associated antigen 4 (CTLA-4) and programmed death 1 (PD-1), have been shown to increase survival of patients with advanced cancers (1, 2). These in...
