Allogeneic hematopoietic stem cell transplantation (HSCT) demonstrated convincingly the potential of allogeneic T cells in causing sustained remissions in high-risk hematologic malignancies. However toxicity of allogeneic HSCT limits its application to a broader group of patients. An improved understanding of NK biology along with mechanisms of natural killer (NK) cell and T-cell-mediated alloreactivity against leukemia has led to several clinical immunotherapeutic strategies that preserve graft versus leukemia (GVL) while minimizing the toxicity of HSCT. Here we review strategies being explored both in HSCT and non-HSCT settings that include an emphasis on two key aspects: (a) Maximizing cytotoxicity of alloreactive cells, ie, NK cells and T cells, and (b) Targeted manipulation of critical pathways in T and NK cells contributing to sustained anti-leukemia effects.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
