Could the Measles Virus Be a Ray of Hope for Patients with Multiple Myeloma Who Do Not Respond to Treatment?

According to the results of an experimental study published in the Mayo Clinic Proceedings in May, administration of the measles virus produced a favorable response in the course of the disease in two female patients with multiple myeloma whose disease had relapsed and was resistant to other treatments.

Multiple myeloma is an incurable bone marrow cancer. The results of an experimental study published in the Mayo Clinic Proceedings in May were found to be highly promising. The researchers reported that, after receiving only a high single dose of the measles virus, a female patient with multiple myeloma who had exhausted all treatment options had remained alive without any signs of disease for more than 6 months.

A single dose of the measles virus, modified so as not to damage other cells, was administered intravenously to two patients to kill cancerous plasma (myeloma) cells. The study consisted of patients whose cancer had previously relapsed repeatedly and who had not responded to other treatments. As emphasized by the scientists conducting the study at the Mayo Clinic, both patients responded to treatment; both the amount of cancerous tissue in the bone marrow and myeloma protein levels decreased. Furthermore, one of the female patients, who was 49 years old, had a complete response to treatment without showing any signs of disease for more than 6 months.

Evidence that virotherapy works in the treatment of metastatic cancer!

The first trials of virotherapy in cancer date back to the 1950s. This type of treatment, using oncolytic viruses (common cold, herpes, and smallpox viruses), has been administered to hundreds of thousands of patients. However, this study is the first to evaluate the efficacy of systemic oncolytic virotherapy in metastatic cancer.

Myeloma is a relatively uncommon type of cancer that develops from plasma cells, a type of blood cell produced in the bone marrow. Myeloma can originate in the bone marrow anywhere in the body, such as the spine, ribs, and pelvis. It is called multiple myeloma because it occurs in multiple areas.

This disease, which can also cause tumors to form in bone and soft tissue, generally responds to drugs that stimulate the immune system, but eventually overcomes the immune system and can rarely be completely cured.

Measles is a childhood disease caused by a virus. Thanks to the vaccine developed for measles, it is now possible to achieve complete protection against the disease. Although it is almost never seen in countries where vaccination programs are well implemented, nearly one hundred thousand children worldwide still die each year from measles.

First use of the reengineered measles virus at the highest possible dose

The two patients with multiple myeloma who participated in the study were selected because they had previously been exposed to measles to a limited extent and therefore did not have large amounts of antibodies against the measles virus in their immune systems. The patients had also used other oncological treatment options.

To explain the mechanism in simple terms, the reengineered measles virus enters cancer cells and causes the cells to burst. In addition, this treatment triggers other mechanisms, causing myeloma cells to be recognized more effectively by the immune system in the future.

The research team has also begun testing the virus's effects on head and neck, brain, and ovarian cancers, as well as mesothelioma. In addition, other viruses capable of killing cancer cells are being investigated and efforts are being made to reengineer them.

As can be seen, the maturation of the idea of using viruses in cancer treatment, whose foundations date back to the 1950s, and the development of the appropriate environment and body of knowledge needed to turn it into scientific research can take years. There is a time when every word will gain strength and come true. I hope that the scientists involved in this research, whose effects have not yet been proven because it is still at the experimental stage, will continue their work without slowing down and that cures will be found in the near future for many diseases that are now considered untreatable.
