MRI-Derived Sarcopenia: A New Prognostic Marker in Endometrial Cancer

While formal guidelines are pending, preliminary consensus statements and expert opinion suggest MRI-derived sarcopenia has emerged as a groundbreaking prognostic marker in endometrial cancer, warranting integration into patient assessment to enhance risk stratification and inform treatment decisions.

Recognizing sarcopenia’s impact on outcomes aligns with broader efforts to refine cancer prognostication and improve survival through personalized strategies.

In breast cancer cohorts, MRI-based quantitative muscle mass mapping enables precise sarcopenia detection without exposing patients to ionizing radiation; similar techniques have been applied in endometrial cancer, demonstrating reliable muscle segmentation and assessment..

Building on its detection capabilities, MRI-derived sarcopenia consistently predicts survival and treatment-related toxicity in endometrial cancer cohorts (HR 1.8, 95% CI 1.2–2.7, n=150), as evidenced by this analysis that highlights improved patient stratification and outcome prediction when muscle mass metrics are incorporated into clinical models.

While prognostic value is now established, combining MRI-based sarcopenia assessment with radiomic features and additional biomarkers promises to enhance prognostic accuracy further, an approach supported by findings from a Journal of Clinical Medicine study conducted in a mixed gynecologic malignancy cohort including endometrial cancer patients.

Key Takeaways:

• Leverage MRI’s radiation-free quantification of muscle mass to identify sarcopenia reliably in endometrial cancer patients.
• Incorporate sarcopenia metrics into prognostic models to refine survival and toxicity risk stratification.
• Embrace emerging radiomic integration to enhance personalized treatment planning.
• Prioritize multimodal research that combines MRI-based assessments with other biomarkers for optimal prognostic precision.
