Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.6K
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...

Cancer Therapies

7.6K
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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

520
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

3.3K
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

359
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...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

4.9K
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...

Summary

Traditional cancer therapies kill cells, promoting resistance. New strategies aim to re-educate cancer cells towards a less malignant state, potentially preventing therapy resistance and tumor progression.

Area of Science:

  • Oncology
  • Cancer Biology
  • Therapeutic Development

Background:

  • Conventional anticancer treatments focus on inhibiting cancer cell proliferation.
  • Cytotoxic therapies induce selective pressure, favoring the survival of resistant cancer cell populations.
  • This resistance is a primary cause of tumor progression and treatment failure.

Purpose of the Study:

  • To propose novel therapeutic strategies targeting cancer hallmarks beyond proliferation.
  • To explore methods for re-educating cancer cells toward a less malignant phenotype.
  • To circumvent the development of adaptive resistance in tumors.

Main Methods:

  • Targeting cancer cell dormancy.
  • Employing transdifferentiation therapy.
  • Normalizing the tumor microenvironment.
  • Utilizing migrastatic therapy.

Main Results:

  • Proposed strategies aim to alter cancer cell phenotype rather than eradicate cells.
  • Adaptive resistance to these 'educative' strategies does not provide a proliferative advantage.
  • Non-resistant cells are not eliminated, thus preserving a less aggressive cell population.

Conclusions:

  • Alternative therapeutic strategies targeting non-proliferative cancer hallmarks offer a promising approach.
  • Re-educating cancer cells may delay or prevent the emergence of therapy-resistant tumors.
  • Focusing on phenotypic plasticity rather than direct killing could overcome treatment resistance.
