Hormonal therapy in early and advanced breast cancer
1The University of Texas M D Anderson Cancer Center, Houston, Texas 77030, USA.
Abstract:
While some of the most intriguing data on the development of hormonal therapy for breast cancer have come from studies on aromatase inhibitors (AIs), few trials have compared these agents directly, with the exception of the Arimidex, Tamoxifen, Alone or in Combination (ATAC) trial. Based on the latest results from this trial and on previous investigations of other AIs, a proposed sequence of hormonal therapies (including anastrozole, tamoxifen, letrozole, fulvestrant, and megestrol acetate) for the treatment of breast cancer is beginning to emerge for various patient populations.
Insights
Hormonal therapy for breast cancer is evolving. Aromatase inhibitors (AIs) and other agents like tamoxifen are being sequenced for improved treatment outcomes in diverse patient groups.
Area of Science:
- Oncology
- Endocrinology
- Pharmacology
Background:
- Aromatase inhibitors (AIs) represent a significant advancement in hormonal therapy for breast cancer.
- Direct comparative trials of different AIs are limited, with the Arimidex, Tamoxifen, Alone or in Combination (ATAC) trial being a notable exception.
Purpose of the Study:
- To propose an optimal sequence of hormonal therapies for breast cancer treatment.
- To integrate findings from the ATAC trial and other AI investigations.
Main Methods:
- Analysis of data from the ATAC trial.
- Review of previous investigations on various aromatase inhibitors and other hormonal agents.
Main Results:
- Emerging evidence suggests a potential sequence for hormonal therapies.
- The proposed sequence considers different patient populations and treatment histories.
Conclusions:
- A structured approach to hormonal therapy sequencing is becoming clearer.
- This evolving strategy aims to optimize breast cancer treatment outcomes using agents like anastrozole, tamoxifen, letrozole, fulvestrant, and megestrol acetate.

Cancer Therapies
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...
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
