Insights

New therapies targeting human epidermal growth factor 2 (HER-2)-positive breast cancer significantly improve survival. This review covers approved treatments and emerging HER-2-directed drugs for both HER-2-positive and HER-2-low breast cancer.

Area of Science:

  • Oncology
  • Pharmacology
  • Genetics

Background:

  • Human epidermal growth factor 2 (HER-2)-positive breast cancer is an aggressive subtype with a poor prognosis.
  • HER-2-targeted therapies have revolutionized treatment, improving survival and quality of life.
  • Recent advances include therapies for HER-2-low breast cancer, expanding treatment options.

Purpose of the Study:

  • To summarize recently approved therapeutic strategies for HER-2-positive breast cancer.
  • To review novel and investigational HER-2-targeted therapies in development.
  • To highlight advances in treating both HER-2-positive and HER-2-low breast cancer.

Main Methods:

  • Literature review of recent clinical trials and regulatory approvals.
  • Analysis of emerging therapeutic targets and drug development pipelines.
  • Synthesis of data on survival benefits and treatment efficacy.

Main Results:

  • Several new HER-2-targeted therapies have gained approval, demonstrating significant survival benefits.
  • Ongoing research is exploring novel agents and combinations for HER-2-positive and HER-2-low breast cancer.
  • The landscape of HER-2-directed therapy is rapidly evolving with promising new treatments.

Conclusions:

  • Approved HER-2-targeted therapies have markedly improved outcomes for patients with HER-2-positive breast cancer.
  • The development pipeline for HER-2-directed therapies is robust, offering future treatment advancements.
  • The recognition of HER-2-low breast cancer's response to these therapies broadens their clinical impact.

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...

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...

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.

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...

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...
