Which Treatment is Better for Cancer: Monoclonal Antibodies (mAbs) or CAR-T Cells?

Choosing between monoclonal antibodies (mAbs) and CAR-T cells (Chimeric Antigen Receptor T-cell therapy) to treat cancer is a complex decision that depends on various factors, including the type of cancer, previous treatments, and the patient's overall health. Both treatments have their unique advantages and limitations, making them suitable for different scenarios.

Monoclonal Antibodies (mAbs): A More Tolerable Option

In general, if cancer can be effectively treated with a monoclonal antibody, this approach is often preferred due to its better tolerability. Monoclonal antibodies are designed to recognize and target specific antigens on the surface of cancer cells, thereby offering focused treatment to minimize damage to healthy cells. This targeted approach is particularly beneficial for patients who have already undergone extensive and intensive treatments, such as chemotherapy or radiation therapy, and are looking for a gentler alternative.

Chimeric Antigen Receptor T-cells (CAR-T Cells): A Last Resort Option

Chimeric Antigen Receptor T-cell therapy is typically reserved as a last resort when standard treatments have failed. CAR-T involves genetically modifying the patient's own T cells to express a receptor that recognizes and attacks cancer cells. Although highly effective in certain cases, this treatment is not universally applicable and comes with significant risks and challenges.

Limitations of CAR-T Cells

Not all cancers are currently targetable with CAR-T cells. Additionally, the procedure is highly intensive and requires close monitoring, often necessitating a stay in the Intensive Care Unit (ICU). The therapy can cause severe side effects, including cytokine release syndrome (CRS) and neurotoxicity. Moreover, some patients may not survive the intensive treatment process due to the hyperimmune reactions it can induce.

Economic Considerations

The cost of CAR-T cell therapy is substantial. It typically involves a high upfront cost for the production of personalized cells and additional costs for the delivery of the treatment. According to recent figures, CAR-T therapy can cost around $500,000 for the initial cell production and another $500,000 for the delivery, making it a financial burden for many patients and their families.

Other Considerations

The effectiveness of both mAbs and CAR-T cells can vary depending on the type of cancer. For instance, some forms of lymphoma have shown significant improvement with the use of monoclonal antibodies. However, the response to CAR-T treatment is more specific and depends on the availability of suitable antigens on the cancer cells.

Fasting and Chemo Sensitization

A recent study has suggested that fasting prior to chemotherapy can sensitize cancer cells to chemotherapy and potentially reduce its side effects. While this is an emerging area of research, it offers another potential strategy for optimizing treatment protocols. Patients undergoing chemotherapy may want to discuss this option with their oncologist to determine if it is a viable approach.
