Insights

Oestrogen receptor-negative and triple-negative breast cancers are aggressive subtypes lacking effective treatments. This study reviews current research to identify new therapeutic pathways and agents for these challenging mammary tumours.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Oestrogen receptor-negative (ER-) and triple-negative breast cancers (TNBC) are aggressive subtypes.
  • These tumours account for a significant proportion of breast cancer diagnoses (approximately 30% and 15%, respectively).
  • Current endocrine therapies like selective oestrogen receptor modulators and aromatase inhibitors are ineffective against these subtypes.

Purpose of the Study:

  • To conduct a state-of-the-art review on the treatment and prevention of ER-negative and TNBC.
  • To identify novel therapeutic pathways, biomarkers, and drug agents for these aggressive breast cancer subtypes.

Main Methods:

  • Comprehensive literature search and review of existing studies.
  • Analysis of current research on drug classes under investigation for ER-negative and TNBC.
  • Synthesis of state-of-the-art findings on therapeutic strategies.

Main Results:

  • Identified limitations of current treatments for ER-negative and TNBC.
  • Highlighted the need for novel therapeutic approaches.
  • Summarized various drug classes and agents currently under investigation.

Conclusions:

  • There is an urgent need for effective treatment and prevention strategies for ER-negative and TNBC.
  • Ongoing research into new pathways, biomarkers, and agents is crucial.
  • This review provides a current overview of the therapeutic landscape for these aggressive breast cancers.

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
Preventive Healthcare Services01:30

Preventive Healthcare Services

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:
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...
Treatment Resistent Cancers02:56

Treatment Resistent 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...
