Clinical Report: Vaginal Microbiome Changes and Genitourinary Syndrome of Menopause

Overview

This study protocol aims to investigate the effects of endocrine therapy on the vaginal microbiome and genitourinary syndrome of menopause (GSM) in premenopausal breast cancer patients. It will assess microbiome diversity and its relationship with GSM severity over a longitudinal period.

Background

Breast cancer is the most prevalent malignancy among women, with a rising incidence among younger populations. Endocrine therapy is crucial for hormone receptor-positive breast cancer but often leads to GSM due to hypoestrogenism. Understanding the impact of these therapies on the vaginal microbiome is essential for improving patient quality of life.

Data Highlights

This study will enroll 110 premenopausal women with hormone receptor-positive breast cancer, assessing microbiome changes and GSM symptoms over 12 months.

Key Findings

• Endocrine therapy can induce GSM symptoms in young breast cancer survivors.
• Approximately 70% of patients experience GSM symptoms post-treatment.
• The study will utilize 16S rRNA sequencing for microbiome analysis.
• Primary outcomes include microbiome diversity and Lactobacillus abundance.
• Secondary outcomes will assess GSM symptoms and urinary health.

Clinical Implications

The findings from this study may inform personalized interventions for managing GSM in breast cancer survivors. Understanding microbiome changes could lead to improved treatment adherence and quality of life.

Conclusion

This longitudinal study aims to elucidate the relationship between endocrine therapy, vaginal microbiome changes, and GSM, potentially guiding future therapeutic strategies.
