Drugs such as venetoclax and ivosidenib have shown effectiveness in certain subsets of AML patients, particularly those with specific genetic mutations.
Targeted therapies generally have a more favorable side effect profile compared to conventional chemotherapy. They can often be used in combination with other treatments to enhance efficacy. For example, venetoclax is often combined with azacitidine or decitabine for patients who may not tolerate intensive chemotherapy due to age or comorbidities.
Understanding the genetic profile of AML can open possibilities for targeted therapies, making it essential to conduct thorough genetic testing on newly diagnosed patients.
Stem Cell Transplantation
Stem cell transplantation, also known as hematopoietic stem cell transplantation, is often considered for eligible patients after initial remission. This approach involves the infusion of healthy stem cells that can regenerate the blood and immune system following the aggressive treatments often used for AML.
There are two main types of stem cell transplants: autologous, where the patient's own cells are used, and allogeneic, where cells from a compatible donor are used. Allogeneic transplantation is generally favored for its potential to eradicate residual leukemia, but it comes with serious risks, including graft-versus-host disease (GVHD).
Patients eligible for this procedure should be evaluated thoroughly to ensure that the benefits outweigh the risks. Factors such as age, overall health, and genetic makeup will significantly influence the decision to proceed with this modality. The potential for long-term survival increases notably with successful transplantation, especially in younger and healthier patients.
In summary, the choice of treatment modalities in AML plays a critical role in shaping patient outcomes, both during and after therapy. As our understanding of AML deepens, the pathway to personalized treatment approaches becomes clearer, ideally leading to improved survival rates.
