Skeletal Muscle Mass Changes on Images for Prediction of Prognosis After Exercise Training in HNSCC Patients

This project adopts a prospective study design. It is scheduled to enroll 60 participants diagnosed with Head and Neck cancer in this hospital, of which 30 are in the experimental group and 30 are in the control group. The purpose of this research is to analyze the skeletal muscle mass changes on images in Head and Neck cancer patients after exercise training and the association with systemic inflammatory markers. Investigators would like to know whether these images and biomarkers predict the prognosis of Head and Neck cancer. Subjects enrolled in the trial will receive 36 times of exercise training after concurrent chemoradiotherapy. Before and after the completion of exercise training, investigators will arrange (1) dual energy X-ray absorptiometry (DXA) to measure the whole-body skeletal muscle mass and appendicular skeletal muscle mass and (2) blood tests for markers of systemic inflammation. In addition to DXA, computed tomography (CT) is another image modality for skeletal muscle mass evaluation. Positron emission tomography - CT or whole-body CT for cancer staging are considered as baseline studies. The routine follow-up CT images are used to analyze the changes after exercise training. If magnetic resonance imaging is also performed during the follow-up period, images will also be collected and assessed as an alternative.If the experimental group can maintain or even improve skeletal muscle mass and can be reflected in blood tests and prognosis, the result may be able to apply on cancer treatment and disease followup.
