Inverse Treatment Planning and Stereotactic Intensity-Modulated Radiation Therapy (IMRT) of the Tumor and Lymph Node Levels for Nasopharyngeal Carcinomas Description of Treatment Technique, Plan Comparison, and Case Study

摘要

Inverse treatment planning and intensity-modulated radiation therapy (IMRT) promise advantages in the treatment of tumors of the head and neck region. Currently published studies use IMRT only in the treatment of the primary tumor. In these studies, the lymph nodes of the neck were treated using conventional techniques. The feasibility of an IMRT technique with allows treatment of the complete target volume, including the primary tumor and lymph nodes, without a beam split is described.
