TY - JOUR T1 - Prediction of the lung adenocarcinoma metastatic spread according to initial CT examination JF - European Respiratory Journal JO - Eur Respir J VL - 38 IS - Suppl 55 SP - p3663 AU - Tamara Milosavljevic AU - Aleksandar Ivkovic Y1 - 2011/09/01 UR - http://erj.ersjournals.com/content/38/Suppl_55/p3663.abstract N2 - Adenocarcinoma of the lung gives a wide specter of different metastatic spread. Often we can find them before primary neoplasm. Therapy and prognosis depends not only on possibility of medicament or surgical treatment but also on location of neoplasm.Aim of the study is to show spread direction of lung adenocarcinoma according to localization of primary neoplasm followed by computerized tomography.Material and methods: This is study of 4356 patients with 14528 CT examinations. All patients were with adenocarcinoma of the lung. All examination were performed on 16 or 64 MDCT, using virtual bronchoscopy were it was possible. Metastatic spread was followed by conventional radiography, ultrasound, scintigraphy, MDCT and MRI according on location. Male patients were 2821 (64.76%), female 1535 (35.24%). Middle age of patients was 68.3 years.Results: We divided results according to lobar anatomy parts of the first sign of neoplasm on initial CT examination, with hilar presentation of neoplasm like separate entity. Neoplasm of both upper lung lobes were spread dominantly on supra renal gland (67.14%), after that on liver and then on bones. Neoplasm of middle right lobe was spread in both hilar regions. Basal tumors are mostly spread in bones (34.73%) and after that in liver. Hilar neoplasm spread to brain mostly (76.36%). Second group were patients were we find metastatic spread before primary neoplasm and on second examination lung adenocarcinoma.Conclusion: Spread prediction of lung neoplasm is very important for therapy and prognosis. CT is golden standard for evaluation. ER -
