The right and left lungs can be contoured separately, but they should be considered as one structure for lung dosimetry. All inflated and collapsed, fibrotic and emphysematic lungs should be contoured, small vessels extending beyond the hilar regions should be included; however, pre GTV, hilars and trachea/main bronchus should not be included in this structure.HeartHeart & PericardiumThe heart will be contoured along with the pericardial sac. The superior aspect (or base) will begin at the level of the inferior aspect of the pulmonary artery passing the midline and extend inferiorly to the apex of the heart.EsophagusEsophagusThe esophagus should be contoured from the beginning at the level just below the cricoid to its entrance to the stomach at GE junction. The esophagus will be contoured using mediastinal window/level on CT to correspond to the mucosal, submucosa, and all muscular layers out to the fatty adventitia.SpinalcordSpinal CanalThe spinal cord will be contoured based on the bony limits of the spinal canal. The spinal cord should be contoured starting at the level just below cricoid (base of skull for apex tumors) and continuing on every CT slice to the bottom of L2. Neuroformanines should not be included. BrachialplexBrachial PlexusThis is only required for patients with tumors of upper lobes. Only the ipsilateral brachialplex is required. This will include the spinal nerves exiting the neuroforamine from top of C5 to top of T2. In contrast to prior RTOG lung studies of contouring the major trunks of the brachial plexus with inclusion of subclavian and axillary vessels, this trial requests contouring the nerves according to the CT anatomy on every other CT slice. The structure should extend at least 3 cm above the PTV. RTOG 1106 Required OARsStructu 3本文档所提供的信息仅供参考之用，不能作为科学依据，请勿模仿；如有不当之处，请联系网站或本人删除。

RTOG 1106 Optional OARsStructure DescriptionStructure definition and contouring instructionsPericardPericardiumThe structure of pericardium includes pericardial fatty tissue, part of great vessels, normal recesses, pericardial effusion (if applicable) and heart chambers. Pericardium starts at one slice above the top of aortic arch, ends at the last slice of heart apex at diaphragm. Pericardium includes the heart. GreatvesAortaSVCIVCPVPAGreat vesselsAortaSuperior vena cavaInferior vena cavapulmonary veinpulmonary artery The great vessels should be contoured separately from the heart, using mediastinal windowing to correspond to the vascular wall and all muscular layers out to the fatty adventitia (5 mm from the contrast enhanced vascular wall). The great vessel should be contoured starting at least 3 cm above the superior extent of the PTV and continuing on every CT slice to at least 3 cm below the inferior extent of the PTV. For right sided tumors, SVC will be contoured, and for left sided tumors, the aorta will be contoured. The ipsilateral PA will be delineated for tumor of either side. PbtreeProximal Bronchial TreeThis structure includes the distal 2 cm of the trachea, the carina, the right and left mainstem bronchi, the right and left upper lobe bronchi, the intermedius bronchus, the right middle lobe bronchus, the lingular bronchus, and the right and left lower lobe bronchi. CW2cmChest wall 2 cm outside of lungChest wall can be autosegmented from the ipsilateral lung with a 2-cm expansion in the lateral, anterior, and posterior directions. Anteriorly and medially, it ends at the edge of the sternum. Posteriorly and medially, it stops at the edge of the vertebral body with inclusion of the spinal nerve root exit site. CW2cm which include intercostal muscles, nerves exclude vertebrate bodies, sternum and skin. This can be accomplished through auto-expansion of the ipsilateral lung (within 3 cm range of PTV).RTOG 1106 Optional OARsStructu 4本文档所提供的信息仅供参考之用，不能作为科学依据，请勿模仿；如有不当之处，请联系网站或本人删除。
