Insights

Immunotherapy shows promise for advanced head and neck cancers. This review focuses on human papillomavirus (HPV)-positive oropharyngeal cancers and novel HPV-specific immunotherapies targeting unique tumor antigens.

Area of Science:

  • Oncology
  • Immunology
  • Cancer Research

Background:

  • Head and neck squamous cell carcinoma (HNSCC) treatment is evolving with immunotherapy.
  • Human papillomavirus (HPV) is a key factor in a subset of oropharyngeal cancers (OPC), creating a distinct disease entity.
  • Current management for HPV-positive and HPV-negative HNSCC is similar, despite biological differences.

Purpose of the Study:

  • To review the role of immunotherapy in HPV-positive HNSCC.
  • To highlight clinical evidence and scientific rationale for emerging immunotherapies.
  • To emphasize HPV-specific immune activators targeting foreign tumor antigens.

Main Methods:

  • Review of current clinical trials and preclinical research.
  • Analysis of immunotherapy outcomes in advanced HNSCC, including HPV status.
  • Focus on HPV-specific immune activators.

Main Results:

  • Anti-PD1 checkpoint inhibitors improve outcomes in advanced HNSCC, regardless of HPV status.
  • HPV-positive OPC has unique tumor antigens and immune microenvironment.
  • Numerous clinical trials are exploring refined immunotherapy applications.

Conclusions:

  • Immunotherapy is a rapidly advancing field for HNSCC.
  • HPV-positive HNSCC represents a distinct target for tailored immunotherapy.
  • Exploiting HPV-specific antigens offers a promising therapeutic avenue.

Tumor Immunotherapy01:27

Tumor 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.

Cancer Vaccines01:30

Cancer 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...

Cancer 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...

Targeted Cancer Therapies02:57

Targeted 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.
There are several types of targeted therapies against...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

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...

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
