Summary
Electrochemotherapy (ECT) enhances cancer cell killing but its effects on the immune system are unclear. This review explores ECT
Area of Science:
- Oncology
- Immunology
- Biomedical Engineering
Background:
- Electrochemotherapy (ECT) uses electric pulses to enhance drug delivery for various cancers.
- Established clinical protocols exist since 2006 for ECT.
- ECT effectively reduces local tumor burden through T-cell dependent mechanisms.
Purpose of the Study:
- To review current knowledge on ECT's interaction with the immune system.
- To explore how ECT impacts immune cell populations within tumors.
- To discuss potential for combining ECT with immunotherapy.
Main Methods:
- Literature review of existing studies on ECT and cancer immunology.
- Analysis of immune cell dynamics post-ECT treatment.
- Conceptual framework for electroimmunotherapy development.
Main Results:
- ECT demonstrates T-cell dependent tumor cell killing.
- Abscopal effects (systemic anti-tumor responses) are inconsistently observed.
- Limited understanding of ECT's specific effects on tumor-infiltrating immune cells.
Conclusions:
- Further research is needed to elucidate ECT's immunomodulatory effects.
- Harnessing ECT's immune interactions could lead to novel cancer therapies.
- Development of electroimmunotherapy holds promise for enhanced treatment outcomes.

01:27Tumor Immunotherapy
677
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.

206
Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

01:27Cytotoxic T Cells-mediated Immune Response
2.6K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

02:17The Tumor Microenvironment
6.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

02:50Combination Therapies and Personalized Medicine
5.1K
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...
