Summary
Immunotherapy is transforming cancer care. For gastric cancer, identifying patients who will benefit from immunotherapy, particularly PD-1/PD-L1 inhibitors, is crucial for effective treatment.
Area of Science:
- Oncology
- Immunology
- Gastroenterology
Background:
- Immunotherapy is revolutionizing solid tumor treatment.
- Chemotherapy is the standard for advanced gastric cancer, but novel immunotherapies are emerging.
- Identifying patient subsets who benefit from immunotherapy is a key challenge.
Purpose of the Study:
- To summarize current knowledge on gastric cancer biology and clinical features.
- To explore whether specific molecular subsets of gastric cancer patients benefit more from immunotherapy.
- To review the mechanisms of immune evasion in cancer.
Main Methods:
- Comprehensive literature search on gastric cancer immunotherapy.
- Analysis of immune system regulation (activating/inhibitory signals).
- Review of clinical trial data for immunotherapy agents.
Main Results:
- Gastric cancer can evade immune responses.
- Anti-CTLA-4 antibodies show minimal activity.
- PD-1/PD-L1 inhibitors demonstrate growing efficacy in gastric cancer.
Conclusions:
- Harnessing the immune system is a promising frontier for gastric cancer treatment.
- Predictive factors are essential for optimizing immunotherapy use.
- Further research is needed to identify patient subgroups for immunotherapy.

2.1K
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.

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.

02:38Mitogens and the Cell Cycle
8.2K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

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...
