Abstract

Insights

Triple negative phenotype (TNP) breast cancer is aggressive and lacks targeted therapies. Research is exploring TNP cancer complexity to find new treatment strategies and improve patient survival.

Area of Science:

  • Oncology
  • Genomics
  • Molecular Biology

Background:

  • Triple negative phenotype (TNP) breast cancers lack oestrogen/progesterone receptors and HER2 overexpression.
  • TNP breast cancer exhibits aggressive behavior and poorer survival rates.
  • Limited targeted therapy options exist, with chemotherapy offering poor outcomes.

Purpose of the Study:

  • To discuss TNP cancer characteristics driving current and novel therapeutic strategies.
  • To outline an approach for identifying and validating new therapeutic targets for TNP breast cancer.

Main Methods:

  • Review of TNP cancer characteristics.
  • Discussion of therapeutic strategy rationales.
  • Exploration of methods for new target discovery and validation.

Main Results:

  • Current treatment landscape for TNP breast cancer is limited.
  • Need for novel targeted therapies is emphasized.
  • Ongoing research focuses on understanding TNP heterogeneity.

Conclusions:

  • Large prospective trials are pending.
  • Unraveling TNP heterogeneity using high-throughput techniques is crucial.
  • Integrating molecular findings with biology-driven strategies is key for future treatment development.

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 specific...

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...
Treatment Resistant Cancers02:56

Treatment Resistant Cancers

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...

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.
