Lung cancer is the most common cause of death from cancer for males and the second most common cause of death for females after breast cancer. Several organs were contoured including the lungs airway heart spinal cord body and gross tumor volume GTV.
Current guidelines for esophageal cancer contouring are derived from traditional 2-dimensional fields based on bony landmarks and they do not provide sufficient anatomic detail to ensure consistent contouring for more conformal radiation therapy techniques such as intensity modulated radiation therapy IMRT.

National Lung Screening Trial NLST NEJM 62011 102011 50000 patients Identified lung cancer at an earlier stage 20 lung cancer specific mortality benefit 7 overall mortality benefit 122013 US.
We proposed some schemes to automatically generate and vanish the seeds of the random walks RW algorithm. Guidelines for contouring the mediastinum have been described by others 17 but we have. Atlases for CT Gross Tumor Volume and PET Metabolic Tumor Volume.
Radiotherapy for lung cancer 3 RCR consensus statements wwwrcracuk RCR lung cancer consensus statements 1. Total lung V20. In this study we proposed a semi-automated and interactive scheme for organ contouring in radiotherapy planning for patients with non-small cell lung cancers.
Standardized cross-sectional contouring guidelines are needed due to the increasing use of highly conformal radiotherapy techniques in esophageal and gastroesophageal junction cancer. Statistical and Data Management Center SDMC Meetings Resources. Preventive Services Task Force Recommendation Statement 12012.
Esophageal contours RTOG recommends contouring from the cricoid to the GE junction Esophageal diameter shape and position are variable Pay attention for accurate contours. These were analyzed to generate a consensus atlas. All portions of the duodenum are recommended to be contoured 43.
OAR Contouring for HCC At minimum these structures are required to be contoured at the level of the PTV and over any region received 10 Gy. The approach requires special technologic requirements and contouring expertise to be safely performed. The annual incidence of lung cancer in South East England is 545 per 100000 among men and 278 per 100000 among women average standardised incidence rates 19992003 Thames Cancer Registry.
V30. 1 Draw the pelvic vessels 4 The presacral space tightly and grow 7mm- coverage is crucial at least 1cm margins around upto the S2-S3 junction. In lung cancer it is often difcult to determine the tumour extent on CT scans 19 and even larger inter-clinician variations in contouring can be expected than were seen for well circumscribed tumours such as early-stage prostate cancer 4.
ESMO has Clinical Practice Guidelines on the following Lung and Chest Tumours. V10. However nasopharyngeal carcinoma NPC is a disease unique in its epidemiology and behavior necessitating separate guidelines for this distinctive.
