Summary
Adjuvant endocrine therapy, including tamoxifen and aromatase inhibitors (AIs), is crucial for hormone receptor-positive breast cancer. Ongoing research explores optimal AI use and duration for improved recurrence prevention.
Area of Science:
- Oncology
- Endocrinology
- Pharmacology
Background:
- Endocrine therapy significantly reduces recurrence and mortality in hormone receptor-positive breast cancer.
- Tamoxifen has been the standard adjuvant treatment for decades, particularly for premenopausal women.
Purpose of the Study:
- To review the role of endocrine therapy, specifically aromatase inhibitors (AIs), in adjuvant treatment for breast cancer.
- To discuss current evidence and ongoing research regarding AI efficacy, duration, and comparative effectiveness.
Main Methods:
- Review of clinical trial data comparing tamoxifen and AIs in various adjuvant settings.
- Analysis of studies investigating extended adjuvant therapy and intermittent AI treatment.
Main Results:
- Aromatase inhibitors demonstrate greater efficacy than tamoxifen in preventing recurrence in postmenopausal women.
- AIs have been evaluated in upfront, sequential, and extended adjuvant settings with established benefits.
Conclusions:
- For postmenopausal women, AIs are generally preferred over tamoxifen in the adjuvant setting.
- Further research is needed to determine optimal AI duration, comparative AI effectiveness, and intermittent treatment benefits.

02:57Targeted 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.

02:49Cancer 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...

01:18Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists
Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme (ECE). Of...

01:45Endocrine 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.
