Breast tissue is composed of skin, mammary gland(including lactiferous duct), subcutaneous fat layer. The anatomical position is on the anterior chest wall(the outside of the chest cavity) but not on the inside of the thorax. Therefore, when the internal organs in the thoracic cavity are defined and expressed as 'organs' and the internal organs of each are labeled for a long time, for the breast located outside the thoracic cavity, it is thought that there is considerable difficulty in defining and recognizing the breast tissue as organs. For this reason, it is necessary to discourage the controversy over whether or not the breast is contained in the chest(or intra-thoracic cavity). In order to completely exclude it, it is assumed that the "chest-abdomen" can be called the "intra-thoraxic or intra-abdominal." But it is difficult to change the terms in various laws and regulations, I think that it would be necessary to insert only the clue clause "Breasts are excluded" in the detailed criteria for grading. In order to include it, it is necessary to change the terms of the ordinance or to say that the breast is exceptionally included.

Background : The thoracic and thoracoabdominal aortic surgery is a complicated procedure that has various method of approach and protection. The authors have performed several methods to treat these diseases. Therefore, we attempt to analyze their results and risks. Material and Method: From June of 1992 to August of 2001, we performed 26 cases of thoracic aortic surgery and 10 cases of thoracoabdominal aortic surgery. There were 17 aortic dissections, 17 aortic aneurysms, one coarctation of aorta and one traumatic aortic aneurysm. The thoracic aortic replacement was performed under a femorofemoral bypass, an LA to femoral bypass, or a deep hypothermic circulatory arrest. The thoracoabdominal aortic replacement was performed under a femorofemoral bypass or a pump assisted rapid infusion. Result: There were 7 renal failures, 11 hepatopathies, 7 cerebral vascular accidents, 2 heart failures, 5 respiratory insufficiencies, and 2 sepsis in postoperative period. There were 9 hospital mortalities which were from 2 bleedings, 2 heart failures, 2 renal failures, a sepsis, a respiratory failure, and a cerebral infarction. There were 3 late deaths which were from ruptured distal anastomosis, cerebral infarction, and pneumonia. Conclusion: Deep hypothermic circulatory arrest was not good supportive methods for thoracic aortic replacement. Total thoracoabdominal aortic replacement was a high risk operation.

Background: Surgery of descending thoracic or thoracoabdominal aorta has the potential risk of causing neurological injury including spinal cord damage. This study was designed to find out the risk factors leading to spinal cord and brain damage after surgery of descending thoracic and thoracoabdominal aorta. Material and Method: Between October 1995 and July 2005, thirty three patients with descending thoracic or thoracoabdominal aortic disease underwent resection and graft replacement of the involved aortic segments. We reviewed these patients retrospectively. There were 23 descending thoracic aortic diseases and 10 thoracoabdominal aortic diseases. As an etiology, there were 23 aortic dissections and 10 aortic aneurysms. Preoperative and perioperative variables were analyzed univariately and multivariately to identify risk factors of neurological injury. Result: Paraplegia occurred in 2 (6.1%) patients and permanent in one. There were 7 brain damages (21%), among them, 4 were permanent damages. As risk factors of spinal cord damage, Crawford type II III(p=0.011) and intercostal artery anastomosis (p=0.040) were statistically significant. Cardiopulmonary bypass time more than 200 minutes (p=0.023), left atrial vent catheter insertion (p=0.005) were statistically significant as risk factors of brain damage. Left heart partial bypass (LHPB) was statistically significant as a protecting factor of brain (p=0.032). Conclusion: The incidence of brain damage was higher than that of spinal cord damage after surgery of descending thoracic and thoracoabdominal aorta. There was no brain damage in LHPB group. LHPB was advantageous in protecting brain from postoperative brain injury. Adjunctive procedures to protect spinal cord is needed and vigilant attention should be paid in patients with Crawford type II III and patients who have patent intercostal arteries.

Purpose: To evaluate the inter-fractional position and respiratory reproducibility of lung and liver tumors using pressure conserving type(P-type) abdominal compressor in volumetric modulated arc therapy(VMAT). Materials and methods: Six lung cancer patients and three liver cancer patients who underwent VMAT using a P-type abdominal compressor were included in this study. Cone-beam computed tomography(CBCT) images were acquired before each treatment and compared with planning CT images to evaluate the inter-fractional position reproducibility. The position variation was defined as the difference of position shift values between target matching and bone matching. 4-dimensional cone-beam computed tomography(4D CBCT) images were acquired weekly before treatment and compared with planning 4DCT images to evaluate the inter-fractional respiratory reproducibility. The respiratory variation was calculated by the magnitude of excursions by breathing. Results: The mean ± standard deviation(SD) of overall position variation values, 3D vector in the three translational directions were 1.1 ± 1.4 mm and 4.5 ± 2.8 mm for the lung and liver, respectively. The mean ± SD of respiratory variation values were 0.7 ± 3.4 mm (p = 0.195) in the lung and 3.6 ± 2.6 mm (p < 0.05) in the liver. Conclusion: The use of P-type compressor in lung and liver VMAT was effective for stable control of inter-fractional position and respiratory variation by reproduction of abdominal compression. Appropriate PTV margin must be considered in treatment planning, and image guidance before each treatment are required in order to obtain more stable reproducibility

Background: Thoracoabdominal aortic replacement is an extensive operation that opens both the pleural cavity and abdominal cavity, which has high mortality and morbidity rate. The authors have reported 9 cases of the thoracoabdominal aortic replacement in 2001. Since 2003 we have applied the deep hypothermic circulatory arrest to the Crawford type I and II thoracoabdominal aortic replacement. Therefore, we analysed the effect of the changes in operative techniques. Material and Method: Between 1996 and 2005, we have performed 20 cases of thoracoabdominal aortic replacement. The underlying diseases were 8 cases of atherosclerotic aneurysm with 4 cases of ruptured aneurysm and 12 cases of aortic dissection with 10 cases of a previous operations. According to Crawford classification, there were 2 cases of type I, 7 cases of type II, 1 case of type III, 7 cases of type IV, and 3 cases of type V. We compaired the results of the patients who underwent thoracoabdmoninal replacement before 2001 which already has been reported and after then. Result: Before 2001 we have performed 9 cases of thoracoabdominal replacement and 5 patients were died of the operation. All three patients with type I and II were died. There was no case of thoracoabdominal replacement between 2001 and 2002, but after 2003 we have performed 11 cases of thoracoabdominal replacement which involved 1 case of type I, 5 cases of type II, 1 case of type III, 2 cases of type IV and 2 cases of type V. There was no mortality and no fetal complications. Conclusion: The deep hypothermic circulatory arrest is a safe method of extended thoracoabdominal aortic replacement.

Gastrointestinal stromal tumor is documented on every part of the gastrointestinal tract. It develops in the stomach and the small intestine most commonly, and also in the esophagus. A 44 year-old male patient was admitted due to dysphagia and weight loss. Chest CT showed about $15\times11\times11cm$ sized, well-defined, and lobulated soft tissue mass with central necrosis was noted in the posterior wall of lower esophagus throughout the lesser curvature of upper stomach. We performed the distal esophagectomy and total gastrectomy using thoracoabdominal incision. The tumor was positive at CD117 (c-kit) and CD 34, and was diagnosed as malignant GIST of the distal esophagus and upper stomach. The patient is on routine follow up at the out patient department for nineteen months up to now.
