Evaluaci\'on del Cambio en la Musculatura y Adiposidad y su Relaci\'on con la Recurrencia del Carcinoma de Cabeza y Cuello mediante PET/CT y MRI

Abstract

This study investigates the impact of changes in body composition and follow-up imaging modalities on recurrence and prognosis in patients with head and neck squamous cell carcinoma (HNSCC). The results indicate that an increase in the adiposity index post-radiotherapy is significantly associated with higher recurrence and mortality rates. Additionally, the combined evaluation of muscle and adipose status reveals that patients with muscle loss and adipose gain have the lowest survival probabilities and the highest risk of recurrence. These findings underscore the importance of monitoring adiposity and muscle status, as well as the strategic use of advanced imaging techniques such as PET/CT, MRI, and CT. However, this work represents a preliminary analysis, and further detailed studies are necessary to confirm these results and develop more effective strategies.
