Disclaimer, National Library of Medicine It should be noted that imaging modalities other than CT, such as MRI, might improve visualization of the larynx and surrounding structures. Bladder [0534]: should be contoured from its base to the dome, excluding the CTV1 (the CTV1 includes the bladder neck). The postero-lateral wall of the aryepiglottic folds forms the medial wall of the pyriform sinuses and is part of the hypopharynx. The Radiation Therapy Oncology Group (RTOG) head and neck protocol 1016 identifies the larynx as the "triangular prism shaped volume that begins just inferior to the hyoid bone and extends to the cricoid cartilage inferiorly and extends from the anterior commissure to include the arytenoids.

Bethesda, MD 20894, Web Policies Albert Einstein College of Medicine (Einstein) Other sets of proposed guidelines for the larynx have been put forward but are sparse; none provide clear, comprehensive guidelines for delineating the larynx in its entirety [7],[12],[14]-[16]. Further validation within the context of a prospective clinical trial is required in order to assess if utilizing this contouring approach would result in lower incidence of treatment-induced adverse events; mainly hoarseness of voice, aspiration and dysphagia.

This has prompted the Radiation Therapy Oncology Group (RTOG) to require larynx contours with dose constraints of mean dose ranging from 36 to 45Gy on many recent protocols. 1st edition.

However, to date there has been no validated standardized approach for contouring the larynx and its substructures on axial computed tomography (CT) scans or magnetic resonance imaging (MRI) scans used for radiotherapy treatment planning (Table1). tions of cancers of lung, larynx, oral cavity and pharynx, oesophagus, pancreas, kidney, and bladder due to smoking, 15% (1.1 million new cases per year) of all cancer cases worldwide are attributed to smoking (25% of cases worldwide in men, 4% in women). the larynx as the triangular prism shaped volume that begins just inferior to the commissure to include the arytenoids. 10.1016/j.ijrobp.2004.05.050, Caglar HB, Tishler RB, Othus M, Burke E, Li Y, Goguen L, Wirth LJ, Haddad RI, Norris CM, Court LE, Aninno DJ, Posner MR, Allen AM: Dose to larynx predicts for swallowing complications after intensity-modulated radiotherapy.

Cox JD et al. The atlas makes use of several prominent anatomy landmarks to estimate the position of BP. The authors declare that they have no competing interests. These guidelines should be validated and can be used as a research tool to understand clinical significance of contouring laryngeal substructures and their importance in dose-optimization. Examples of the OARs are shown in Figure3. Towards this end, our study can serve as a research tool in contouring and investigating dose-volume constraints of laryngeal substructures.

Since there is evidence in the literature that the larynx is larger in men than in women, we also decided to look at larynx volume by gender.

Rectum [0534]: should be contoured from the anus (at the level of the ischial tuberosities) to the rectosigmoid flexure (this is roughly at about 10 cm) or for a maximum length of 15 cm if the . IROCQA > Resources > Contouring Atlases Contouring Atlases Contouring atlases are developed for use in some clinical trials as a tool to define and plan clinical target radiation dose volumes as part of radiotherapy treatment planning. Identify and contour the infrahyoid epiglottis. Only a limited number of studies have attempted to define the most important anatomic structures whose dosevolume parameters may have a major effect on swallowing. It remains to be seen if any single or multiple laryngeal substructures play a preferential and significant role in speech and swallowing. Because they are difficult to differentiate from one another without direct visualization, identify and contour the aryepiglottic folds and false vocal folds as a single structure. Examples of the OARs are shown in Figures1 and 2. Standardization of delineation protocols should help to improve such optimization of larynx-sparing radiation therapy in head and neck cancer.

The International Nuclear Information System is operated by the IAEA in collaboration with over 150 members. No patients had primary laryngeal cancer. When using these guidelines, it should be noted that differences exist among patients, and the delineation of individual variants should be addressed by the treating physicians.

As such, to validate the accuracy of the CT-based contouring guidelines, the larynx volumes were drawn independently by one radiation oncologist on axial MRI (T1-weighted, pre-contrast sequence) for the same five patients using the CT-based contouring guidelines.

MRI, with its superior soft-tissue contrast, can help to discriminate the laryngeal substructures from surrounding muscle and fat and can provide the best tumor visibility [10],[11]. Using these guidelines, the larynx OARs were contoured on the radiotherapy treatment-planning CT scans using the Pinnacle treatment-planning system (ADAC Philips Pinnacle 3 version 8.6) for five consecutive patients who were undergoing definitive chemoradiation for locally advanced head-and-neck cancer of a non-larynx primary.

However, they omit the adjacent level V region, instead defining the SCLN borders as consisting of: Cranial: the cricoid cartilage; For example, our findings corroborate, using CT scan, the finding by Hollien, et al. variation.10 The RTOG Breast Cancer Atlas11 was published in 2009 and has been the foundation of a number of subsequent breast cancer trials.1214 This contouring atlas was based on multicentre expert consensus to minimize the variability between different physicians. 10.1016/j.otohns.2006.02.001.

However, some investigators express concern that reducing dose to the larynx in this way could compromise dose distribution elsewhere [23]. MRI provides visualization of soft-tissue planes superior to that seen on CT and is frequently used in head and neck cancers for tumor staging and determining surgical resectability [11]. 2nd edition. PubMedGoogle Scholar. Note that the epiglottis forms the anterior wall of the laryngeal vestibule. This study provides initial validation that these contouring guidelines can be applied to radiotherapy planning for CT scans by comparing them to MRI contours. This and other similar guidelines,12,15 are largely based on the fixed It remains unclear which substructures of the larynx, when irradiated, are most associated with swallowing dysfunction.
