Androgen and breast cancer: an update

Area of Science:

• Oncology
• Endocrinology
• Cell Biology

Background:

• Androgens are increasingly recognized for their role in various breast cancer subtypes.
• Their potential as therapeutic agents is a significant area of research, particularly for difficult-to-treat cancers.

Purpose of the Study:

• To review recent advances (last 18 months) in understanding androgen actions in breast cancer.
• To explore the therapeutic potential of androgens in estrogen receptor alpha (ERα) positive and negative breast cancers.
• To discuss androgen receptor associations with patient prognosis and the use of androgen-directed therapies.

Main Methods:

• Literature review focusing on recent studies and clinical developments.
• Analysis of associations between androgen receptor status and breast cancer outcomes.
• Examination of emerging therapeutic strategies involving androgens.

Main Results:

• Androgens are implicated in both ERα-positive (with therapeutic resistance) and ERα-negative breast cancers.
• Androgen receptor status correlates with patient prognosis across different breast cancer subtypes.
• Androgen-directed therapies are being investigated as novel treatment options.

Conclusions:

• Androgens play a crucial role in multiple breast cancer subtypes.
• Translating the understanding of androgen actions into effective clinical therapeutics remains a key future challenge.
