Esophageal cancers are highly malignant tumours with often a poor prognostic, except for minimal lesions treated with surgery. Radiation therapy, or combined radiation and chemotherapy is the most used therapeutic modality, alone or before oesophagectomy. The delineation of target volumes is now more accurate owing the possibility to use routinely the new imaging techniques (mainly PET). The aim of this work is to precise the radio-anatomical particularities, the pattern of spread of esophageal cancer and the principles of 3D conformal radiotherapy illustrated with a clinical case.
食管癌是高度恶性肿瘤，预后通常较差，手术治疗的微小病变除外。放射治疗或放化疗联合是最常用的治疗方式，可单独使用或在食管切除术前行放疗。由于能够常规使用新的成像技术（主要是PET），靶区勾画现在更加精确。本研究旨在明确食管癌的放射解剖学特点、扩散方式以及通过一个临床病例阐述三维适形放疗的原则。
