Summary
Solid tumors contain nonmalignant cells that create an immune-hostile tumor microenvironment. Overcoming this microenvironment is key for effective cancer immunotherapy and developing new therapeutic strategies.
Area of Science:
- Oncology
- Immunology
- Cell Biology
Background:
- Solid tumors comprise malignant cells within a complex tumor microenvironment (TME).
- The TME includes extracellular matrix and diverse nonmalignant cells like myeloid cells, lymphocytes, fibroblasts, and endothelial cells.
- This stromal network establishes a local immunoregulatory environment hostile to anti-tumor responses.
Framework:
- The symposium focused on the molecular and cellular components of the TME.
- Understanding the TME's role in immune evasion is crucial for therapeutic development.
- Identifying targets within the TME is essential for overcoming treatment resistance.
Implementation:
- Recent advances in identifying molecules and cells sustaining the immune-hostile TME were shared.
- The symposium presented therapeutic strategies currently undergoing translation from preclinical models to human clinical trials.
- Discussions highlighted the importance of targeting the TME for successful immunotherapy.
Implications:
- Identifying novel targets within the TME can enhance the efficacy of cancer immunotherapy.
- Translational strategies are being developed to overcome the immunosuppressive TME.
- This research aims to improve outcomes for patients with established solid tumors.

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.
02:17The Tumor Microenvironment
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...

01:30Cancer Vaccines
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...

02:49Cancer Therapies
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...

02:57Targeted Cancer Therapies
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.
