Adenomyosis and endometrial cancer: determining its role as a biological contributor or incidental coexistence

This study shows that adenomyosis does not affect tumor progression or survival outcomes, indicating a neutral role in endometrial cancer prognosis. However, the interpretation of survival statistics is limited by the low recurrence rate. Patients with adenomyosis are younger, have a lower menopause rate, and require less adjuvant therapy. The higher prevalence of endometrial hyperplasia suggests a potential link to tumor pathogenesis. Overall, adenomyosis appears to be an incidental co-occurrence rather than a biological contributor to endometrial cancer.
