Myosteatosis and myopenia may predict oncologic outcomes in patients with rectal cancer receiving preoperative chemoradiotherapy

Key Points

• Myosteatosis and myopenia are associated with poorer oncologic outcomes in rectal cancer patients undergoing treatment.
• Patients with myopenia showed a 30% increase in adverse events during chemoradiotherapy, highlighting risks involved.
• Assessment utilized imaging techniques to evaluate muscle composition in rectal cancer patients receiving preoperative treatment.
• These findings underscore the potential of muscle metrics as prognostic indicators for treatments in rectal cancer.
