Summary
Combining immunotherapy with stereotactic body radiation therapy (SBRT) may overcome treatment resistance. Radiation acts like a vaccine, exposing tumor antigens to enhance the immune response for advanced cancers.
Area of Science:
- Oncology
- Immunology
- Radiation Oncology
Background:
- Immunotherapy has transformed cancer treatment, with ipilimumab approved in 2011.
- Despite successes, therapeutic resistance to immunotherapy is a significant clinical challenge.
- Combining immunotherapy with SBRT is being investigated to improve patient outcomes.
Purpose of the Study:
- To review the interplay between the immune system and cancer.
- To explore the synergistic effects of combining immunotherapy with SBRT.
- To highlight the abscopal effect in the context of combined modality treatment.
Main Methods:
- Review of scientific literature on cancer immunotherapy and SBRT.
- Analysis of immune pathway modulation by combined treatments.
- Discussion of the abscopal effect and its role in enhancing immune response.
Main Results:
- Immunotherapy has shown significant benefits across various cancers.
- SBRT can stimulate systemic anti-tumor immune responses when combined with immunotherapy.
- The abscopal effect, where non-irradiated tumors respond, is potentiated by this combination.
Conclusions:
- Combining immunotherapy with SBRT offers a promising strategy to overcome treatment resistance.
- Radiation therapy can enhance immunotherapy efficacy by acting as a tumor antigen vaccine.
- This combined approach holds potential for patients with advanced-stage malignancies.

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.

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...

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...

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
