PURPOSE The aim of this study was to evaluate the efficacy of PET imaging and compare it with the performance of CT in mediastinal and hilar lymph node staging in potentially operable non-small cell lung cancer (NSCLC). METHODS Fifty-nine patients with potentially resectable NSCLC who underwent preoperative PET and CT imaging were enrolled into this(More)
Although interferon has not been classified in the pathogenesis of sarcoidosis, it may rarely lead to this disease during treatment of chronic hepatitis C. The case of a 36-year-old woman with chronic hepatitis C who developed sarcoidosis within 10 weeks of treatment with recombinant interferon-alpha2a and ribavirin is described and all seven similar cases(More)
INTRODUCTION Primitive neuroectodermal tumors (PNETs) are rare, rapidly progressive, small- round cell tumors with a poor prognosis despite multimodal therapy, including surgery and chemoradiotherapy. The treatment of choice was unknown since no clinical series with surgical therapy had been reported. We evaluated the impact of multimodal treatment in(More)
PURPOSE Pulmonary carcinoid (PC) tumors are rare neoplasms of the lung with good prognosis but diagnosis may be demanding since there is no exclusive modality alone to clearly differentiate a PC tumor. The purpose of this study is to establish the diagnostic features of somatostatin receptor scintigraphy (SRS), comparatively (where available) with 18FDG(More)
AIMS The differential diagnosis of malignant mesothelioma (MM) from benign mesothelial lesions (BML) based on histopathological criteria is sometimes not satisfying and causes diagnostic problems for histopathologists. We aimed to investigate whether the immunohistochemically determined cell proliferation rate and telomerase activity, using Ki-67 and human(More)
Extracranial metastases from meningioma are very rare and among those the lungs are the most common metastatic site. In the literature, pulmonary metastases of meningiomas have been emphasized on their rarity, non-specific imaging findings, and cytologic features. Some definitive MR imaging features of intracranial meningiomas have been described. However,(More)
Thoracic endometriosis is an uncommon disorder. In most cases, the diagnosis is based on history alone and radiographic findings depend on the menstrual cycle. CT findings include ill-defined or well-defined opacities, nodular lesions, cavities, cystic changes and bullous formation. We report a case of pulmonary parenchymal endometriosis with an unusual(More)
PURPOSE To evaluate the effects of body temperature on ventilator-induced lung injury. MATERIAL AND METHODS Thirty-four male Sprague-Dawley rats were randomized into 6 groups based on their body temperature (normothermia, 37 +/- 1 degrees C; hypothermia, 31 +/- 1 degrees C; hyperthermia, 41 +/- 1 degrees C). Ventilator-induced lung injury was achieved by(More)
OBJECTIVES Some of the lung cancer patients who are treated surgically with curative intent ultimately die in the early postoperative period. The aim of this study is to analyze the causes of death within 1 year of resection for lung cancer in our patients. METHODS Six hundred and twenty patients, who underwent resection for lung cancer with a curative(More)
