  肌肉是在人體內最大的器官之一,它構成了總體重的40%-45%,也反映了一個人的整體營養和健康狀況。由於癌症病患往往被營養不良與化學治療毒性所影響,所以這些患者的肌肉量可能會因營養不良或是化療的影響而大幅波動,於是利用肌肉量的減少可以早期偵測以及評估惡病質之嚴重度。目前,電腦斷層掃描(CT)與骨質密度儀(DXA),被認為是最準確的方法量化肌肉,並且已被廣泛地應用於臨床與研究。
  本演講目標是讓觀眾了解肌肉定量的重要性而它如何幫助評估及預測治療的結果。
  Muscle is one of the largest organs in the human body and it constitutes 40-45% of total body weight and also reflects the overall nutrition and health status of a person. In addition, muscle masses can fluctuate greatly in cancer patients, because these patients are often complicated with poor intake and chemotoxicity. Due to these facts, the degree of muscle depletion (sarcopenia) would better reflect the severity of cachexia in a cancer patient than weight loss or body mass index.
Presently, computed tomography (CT) and Dual-energy X-ray absorptiometry (DXA) are considered one of the most accurate methods to quantify muscle, and it has been used widely in both clinical and research aspect.
  The aim of this talk is to stress the importance of quantify muscle mass in monitoring the cancer treatment and outcome.
