Summary
Radioimmunotherapy uses targeted radiation to treat cancer. Alpha radiation, a potent cancer treatment, also triggers an immune response, enhancing its therapeutic potential.
Area of Science:
- Oncology
- Nuclear Medicine
- Immunology
Background:
- Radioimmunotherapy targets cancer cells using radionuclides attached to tumor-specific vectors.
- Alpha emitters are highly effective for treating disseminated cancers and metastases.
Purpose of the Study:
- To explore the potential of alpha radiation in cancer treatment.
- To investigate if alpha radiation can induce immunogenic cell death.
Main Methods:
- Utilized alpha radionuclides coupled to tumor-specific vectors for targeted delivery.
- Assessed the effects of alpha radiation on cancer cells, focusing on cell death mechanisms.
Main Results:
- Demonstrated that alpha radiation can induce immunogenic cell death.
- Confirmed the potent efficacy of alpha emitters against disseminated cancer and metastasis.
Conclusions:
- Alpha radiation holds significant promise for cancer therapy due to its direct cytotoxic effects and ability to stimulate an anti-tumor immune response.
- Further clinical development of alpha-emitting radioimmunotherapy is warranted.

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.

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
