Summary
Metformin may offer a safer alternative for treating endometrial hyperplasia, a precancerous condition, potentially reducing progression to cancer without progestogen side effects. Further research is needed to confirm its efficacy and safety.
Area of Science:
- Gynecology
- Oncology
- Pharmacology
Background:
- Endometrial hyperplasia is a precancerous condition with increasing global incidence.
- Current treatments like progestogens have significant side effects and recurrence risks.
- Metformin, a diabetes drug, shows potential for endometrial hyperplasia reversal.
Purpose of the Study:
- To systematically review the efficacy and safety of metformin for treating endometrial hyperplasia.
- To evaluate metformin's potential to reduce endometrial carcinoma progression.
- To compare metformin with existing treatments and placebo.
Main Methods:
- Comprehensive search of multiple databases and trial registries without language restrictions.
- Inclusion of randomized controlled trials comparing metformin to placebo, no treatment, or active interventions.
- Independent assessment of trial eligibility, risk of bias, and data extraction by two reviewers.
Main Results:
- Primary outcome: histological regression of endometrial hyperplasia.
- Secondary outcomes: hysterectomy rates, abnormal uterine bleeding, quality of life, and adverse reactions.
- Data will be synthesized to determine treatment effectiveness and safety profiles.
Conclusions:
- Metformin presents a promising therapeutic option for endometrial hyperplasia.
- This review will clarify its role in preventing endometrial cancer.
- Findings will inform clinical practice and patient management strategies.
