Abstract

The invention discloses a method for evaluating skeletal muscle indexes of a head and neck tumor patient through CBCT (cone beam computed tomography), which comprises the following steps: measuring the skeletal muscle indexes of the head and neck tumor patient receiving radiotherapy by using an image-guided radiotherapy technology CBCT conventionally used every week before radiotherapy and during radiotherapy of the head and neck tumor patient; compared with an existing skeletal muscle assessment tool, the skeletal muscle assessment method has the advantages of accuracy and small radiation, and the detection cost of a patient is saved; according to the method, skeletal muscle changes of the head and neck tumor patient during radiotherapy can be dynamically evaluated, the skeletal muscle loss percentage is calculated, and a basis is provided for timely clinical nutrition intervention.

Description

technical field [0001] The invention belongs to the technical field of biomechanical measurement, and more particularly relates to a method for evaluating the skeletal muscle index of patients with head and neck tumors by CBCT. Background technique [0002] Head and neck malignant tumors are the seventh most common tumors in the world, but 40% to 50% of patients with head and neck malignant tumors are in locally advanced stage and lose the opportunity for surgery. For inoperable locally advanced head and neck malignancies, radiotherapy combined with chemotherapy is the current standard of care. [0003] Radiation mucositis and radiation esophagitis caused by radiation damage to the mucosa lead to reduced food intake, weight loss, and subsequent malnutrition during radiotherapy. Between 44% and 88% of patients with head and neck tumors developed or worsened malnutrition during radiotherapy. Malnutrition is associated with a series of clinical adverse events such as increase...
