Insights

Endocrine therapy effectively treats estrogen receptor-positive breast cancer but can cause side effects. This review explores the impact of estrogen suppression from multiple scientific perspectives.

Area of Science:

  • Oncology
  • Endocrinology
  • Basic Science

Background:

  • Nearly 270,000 new breast cancer cases in the USA (2019), with over 70% being estrogen receptor-positive.
  • Endocrine therapy, targeting estrogen, is a primary treatment for estrogen receptor-positive breast cancer.
  • Estrogen's vital roles in energy homeostasis and bone health necessitate careful consideration during treatment.

Purpose of the Study:

  • To present a multidisciplinary perspective on the impact of endocrine therapy for breast cancer.
  • To consolidate insights from breast medical oncology, endocrinology, and basic science.

Main Methods:

  • Review of current perspectives on endocrine therapy in breast cancer treatment.
  • Integration of knowledge from clinical and basic science research.

Main Results:

  • Endocrine therapy is effective in approximately 70% of women with estrogen receptor-positive breast cancer.
  • Systemic estrogen inhibition can lead to significant side effects due to estrogen's broader physiological functions.

Conclusions:

  • A comprehensive understanding of endocrine therapy's impact requires integrating clinical and basic science viewpoints.
  • Further research is needed to mitigate side effects while maintaining treatment efficacy.

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...

Endocrine Signaling01:45

Endocrine Signaling

Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.

Cancer Survival Analysis01:21

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Disorders of the Female Reproductive System01:24

Disorders of the Female Reproductive System

The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...
