Summary
Therapeutic bacteria show promise for cancer treatment by stimulating immune responses and direct cell killing. Further research is needed to overcome challenges in translating bacteria-mediated cancer therapy (BCT) into clinical practice.
Area of Science:
- Microbiology
- Oncology
- Immunology
Background:
- Bacteria play crucial roles in human health and some strains possess antitumor properties.
- Bacteria-mediated cancer therapy (BCT) has shown efficacy in preclinical models but faces clinical translation hurdles.
Purpose of the Study:
- To review established therapeutic bacterial strains and their antitumor mechanisms.
- To discuss future directions for bacteria-mediated cancer therapy.
Main Methods:
- Literature review of established therapeutic bacteria strains.
- Analysis of documented antitumor mechanisms.
- Exploration of drug delivery and gene therapy applications.
Main Results:
- Identified mechanisms include immune stimulation, direct cytotoxicity, signal transduction interference, ECM remodeling, neoangiogenesis, and metabolic modulation.
- Therapeutic bacteria can serve as vehicles for drug and gene delivery.
Conclusions:
- Bacteria-mediated cancer therapy offers diverse antitumor strategies.
- Further breakthroughs are essential for successful clinical translation of BCT.

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

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...

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...

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...

01:27Tumor Immunotherapy

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.
