Abstract:
In recent decades, understanding tumorigenesis and the complex interaction between the host and the immune system has been the pillar for significant advances in anticancer therapy. Conventional anticancer therapy (e.g., cut, burn, and cytotoxic drugs) involves multiple targeting of tumor cells. However, the tumor tissue microenvironment can present a dysregulated, stimulating, or subverted immune response which, in turn, reveals pro-tumor activities favoring tumor expansion and progression. Recently, new potential targets have been identified based on immunomodulatory therapies, which are crafted to re-establish the host anti-tumoral immune response. Clinicians should fully understand the intricate interactions between carcinogens, the tumor milieu, the immune system, and traditional anticancer therapies in order to progress and to overcome the refractory/recurrent challenges and morbidity of the disease. Thus, in this article, we highlight the complex milieu of the oral cancer immune response, pointing out potential therapeutic immunotargets for oral squamous cell carcinomas. The impact of traditional anticancer therapy on the immune system is also outlined.
Insights
Understanding the tumor microenvironment
Area of Science:
- Oncology
- Immunology
- Cancer Research
Background:
- Tumorigenesis research is key to advancing cancer therapy.
- The tumor microenvironment influences immune responses, potentially aiding tumor growth.
- Conventional therapies target tumor cells but can be impacted by immune dysregulation.
Purpose of the Study:
- To explore the oral cancer immune microenvironment.
- To identify potential immunotargets for oral squamous cell carcinomas.
- To outline the effects of conventional anticancer therapy on the immune system.
Main Methods:
- Literature review on cancer immunology and therapy.
- Analysis of the tumor microenvironment's role in oral cancer.
- Identification of immunomodulatory targets.
Main Results:
- The tumor microenvironment often exhibits immune dysregulation favoring tumor progression.
- Immunomodulatory therapies aim to restore anti-tumoral immune responses.
- Traditional therapies can alter the immune system's interaction with tumors.
Conclusions:
- A comprehensive understanding of host-immune-tumor interactions is crucial for effective cancer treatment.
- Targeting the oral cancer immune microenvironment offers new therapeutic avenues.
- Further research into immunotargets is needed for oral squamous cell carcinomas.

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...
