Cancer immunotherapy: Breakthrough or "deja vu, all over again"?
1Wadsworth Center, New York State Department of Health and Albany College of Pharmacy and Health Sciences, Albany, NY, USA.
Summary
Cancer immunotherapy history shows cycles of high enthusiasm followed by disappointment, except for viral cancer vaccines. Current immune stimulation strategies offer hope for better outcomes.
Area of Science:
- Oncology
- Immunology
- Medical History
Background:
- Cancer immunotherapy has a long history, marked by initial excitement from anecdotal successes.
- Subsequent controlled clinical trials have often tempered enthusiasm for various immunotherapeutic approaches.
Purpose of the Study:
- To review the historical pattern of enthusiasm and disappointment in cancer immunotherapy.
- To highlight the unique success of cancer vaccines and assess current immune stimulation strategies.
Main Methods:
- Historical review of immunotherapeutic approaches for cancer.
- Analysis of clinical trial outcomes and their impact on enthusiasm.
- Examination of vaccination strategies against cancer-causing viruses.
Main Results:
- Most cancer immunotherapies exhibit a pattern of initial hype followed by diminished expectations.
- Vaccination against cancer-causing viruses stands as a notable exception, having prevented numerous cancers.
- Current approaches focusing on immune stimulation by removing inhibitory blocks are under investigation.
Conclusions:
- The historical trajectory of cancer immunotherapy necessitates cautious optimism for novel strategies.
- Cancer vaccines represent a successful, albeit specific, application of immunotherapy.
- Further research is needed to determine if current immune stimulation methods will yield more consistent, positive outcomes than previous therapies.

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...

3.8K
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 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...

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.

02:53Adaptive Mechanisms in Cancer Cells
7.2K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
