Autologous hematopoietic cell transplantation (AHCT) is usually considered a single high-dose therapy intending to eradicate existing malignant cells from the patient and enabling both hematologic and immune recovery after the graft infusion. In addition to tumor biology and disease status, also the immunologic status of the patient and several factors affecting graft cellular content are crucial for posttransplant outcomes. There is evidence for an immunotherapeutic role of immune effector cells within infused grafts and of importance of immune recovery post-transplant. Here we present the pros and cons of this autograft-versus-tumor effect in myeloma and non-Hodgkin lymphoma, the two most common current indications for AHCT. In addition, we discuss ways to potentially improve current treatment results by enhancing the immunotherapeutic effect of AHCT.

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.

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.
