Abstract

Insights

Triple negative breast cancer (TNBC) lacks effective treatments. Advances in gene expression profiling identify subtypes, offering hope for personalized therapies and improved outcomes for this aggressive breast cancer subtype.

Area of Science:

  • Oncology
  • Genomics
  • Molecular Biology

Background:

  • Breast cancer treatment has advanced significantly with combination chemotherapy, hormonal therapy, and targeted agents.
  • Triple negative breast cancer (TNBC) presents a poor prognosis due to its resistance to current hormonal and targeted therapies.

Purpose of the Study:

  • To highlight the need for a deeper understanding of TNBC pathophysiology, natural history, and treatment options.
  • To discuss the role of molecular subtyping in predicting treatment outcomes for breast cancer.

Main Methods:

  • Review of recent literature on breast cancer subtyping using gene expression profiling.
  • Analysis of the prognostic and predictive value of identified molecular subtypes.

Main Results:

  • Gene expression profiling has classified breast cancers into five distinct molecular subtypes.
  • These molecular subtypes are prognostic, and emerging evidence suggests they can predict treatment response.

Conclusions:

  • Limited understanding of TNBC biology hinders the development of novel therapeutic strategies.
  • Identifying and validating more molecular predictive signatures is crucial for better characterization and optimal treatment design for TNBC.

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...

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...

Cancer02:18

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.
