Multiple myeloma, a type of blood cancer, develops in plasma cells— important components of the immune system. Affecting the bone marrow, the disease results in an overproduction of unhealthy plasma cells that hinder the production of beneficial ones. As per the American Cancer Society, around 32,270 new cases of myeloma are expected in 2020 alone. The silver lining, however, is that treatment for multiple myeloma has seen significant advancements over the years, resulting in a proliferation of effective treatment options.
The traditional route of managing this disease constitutes chemotherapy and corticosteroids, which aim to limit the growth of the malignant cells by impregnating the patient's body with potent cancer-fighting drugs. These often illustrate effective results in controlling the disease's progression.
Breakthroughs in medical technology have resulted in the development of innovative treatment procedures for multiple myeloma. The use of Immunomodulatory drugs such as Lenalidomide and Thalidomide, Proteasome inhibitors, and targeted therapy respond to changing needs and contexts in the patient’s body. These interventions focus on enhancing the natural immune response, limiting the growth and division of myeloma cells, and blocking the chemical signals within these cells that allow them to multiply and survive.
In recent years, stem cell transplants have proven themselves to be an effective treatment for myeloma patients. This involves infusing healthy blood-forming cells into the patient's body to replace the bone marrow destroyed by radiation or high-dose chemotherapy. This treatment has displayed significant success in virus and cancer-free patient outcomes compared to traditional chemotherapy.
Monoclonal antibody treatment is another promising option, which involves the use of laboratory-produced antibodies that can identify and attach to cancer cells. The antibodies are infused into the patient's system, marking the cancer cells to be destroyed by the immune system. Daratumumab and Elotuzumab are two examples of monoclonal antibodies used in treating multiple myeloma.
Another landmark development in myeloma treatment is CAR-T cell therapy, a relatively new, individualized immunotherapy approach. Here, a patient’s T-cells are engineered to equip them with the ability to recognize cancer cells and destroy them. Initial results from clinical trials have offered hope, exhibiting favorable patient responses towards this treatment.
Despite these advancements, a comprehensive cure for multiple myeloma is yet to be found. However, our understanding of the disease, its progression, and treatment responses continues to grow each day. There is hope that through ongoing research and development, a full-fledged cure will soon be in sight, transforming the landscape of multiple myeloma treatment and offering a beacon of hope to thousands of patients worldwide.
