Insights

New targeted therapies and drug combinations show promise for treating breast cancer by interfering with cancer cell growth and spread. This review highlights key studies on these advanced treatments.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Molecular processes driving cancer development enable targeted therapies.
  • Targeted agents disrupt cancer cell machinery, impacting invasion, metastasis, apoptosis, cell-cycle control, and angiogenesis.
  • Key pathways in breast cancer include HER2, EGFR, VEGF, PI3K-M-Tor, IGF/IGFR, PARP1, and HDAC.

Purpose of the Study:

  • To review promising targeted therapies for breast cancer.
  • To present novel combinations of targeted therapies with cytotoxic agents.
  • To inform treatment strategies for breast cancer patients.

Main Methods:

  • Literature review of recent studies on targeted breast cancer therapies.
  • Analysis of targeted agents acting on specific molecular pathways.
  • Evaluation of combination therapies including targeted agents and cytotoxic drugs.

Main Results:

  • Identification of promising targeted agents for breast cancer treatment.

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...

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...
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...
