Insights

Breast cancer is classified by hormone receptors and Her2 status. New therapies targeting molecular pathways may improve outcomes for patients resistant to current treatments.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Breast cancer classification relies on estrogen receptor (ER), progesterone receptor (PR), and Her2 receptor status.
  • Targeted therapies have improved 5-year survival rates for breast cancer patients.
  • A subset of patients exhibit resistance or unresponsiveness to existing therapies.

Purpose of the Study:

  • To explore novel therapeutic strategies for breast cancer.
  • To address treatment resistance in specific breast cancer patient populations.
  • To investigate the potential of molecular pathway and cell cycle regulation-focused therapies.

Main Methods:

  • Review of current breast cancer classification systems.
  • Analysis of targeted therapy efficacy and resistance mechanisms.
  • Evaluation of emerging therapies targeting molecular pathways and cell cycle regulation.

Main Results:

  • Standard breast cancer subtypes are defined by ER, PR, and Her2 expression.
  • Acquired or intrinsic resistance limits the effectiveness of some targeted therapies.
  • Novel therapies show promise for overcoming resistance and improving response rates.

Conclusions:

  • Targeted therapies have enhanced breast cancer survival but face resistance challenges.
  • Focusing on molecular pathways and cell cycle regulation offers new avenues for treatment.
  • Further research into novel therapies is crucial for improving outcomes in resistant breast cancer cases.

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...

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...

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...

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...

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
