Tumor Immunotherapy01:27

Tumor Immunotherapy

664
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.

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.4K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Cancer Vaccines01:30

Cancer Vaccines

516
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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.8K
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.
There are several types of targeted therapies against...

Combination Therapies and Personalized Medicine02:50

Combination 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...

Area of Science:

  • Neuro-oncology
  • Immunology
  • Cancer Therapy

Background:

  • Immunotherapy is effective in blood cancers but limited in central nervous system (CNS) tumors.
  • Barriers include the blood-brain barrier, tumor immune evasion, and immunosuppressive microenvironments.
  • The concept of CNS immune privilege is evolving, with distinct CNS compartments having unique immunological roles.

Purpose of the Study:

  • To review the CNS immune landscape and its effect on immunotherapy.
  • To analyze mechanisms of immune evasion and suppression in CNS tumors.
  • To evaluate clinical trials, challenges, and innovative strategies for CNS tumor immunotherapy.

Main Methods:

  • Comprehensive literature review of CNS immunology and immunotherapy for brain tumors.
  • Analysis of clinical trial data and mechanisms of immune evasion.
  • Evaluation of current challenges and future therapeutic strategies.

Main Results:

  • The CNS immune microenvironment is complex and varies across different compartments.
  • Significant barriers hinder immunotherapy efficacy in CNS tumors.
  • Clinical trials show variable responses, highlighting the need for tailored approaches.

Conclusions:

  • Overcoming CNS-specific barriers is crucial for successful immunotherapy.
  • Personalized, combination, and novel delivery strategies are promising.
  • Further research is needed to optimize precision immunotherapy for CNS tumors.
