BACKGROUND Angiogenesis, the formation of new blood vessels from the existing vascular bed, is essential step for the growth and invasion of the primary tumor. Vascular endothelial growth factor (VEGF) is known to play crucial role in tumor angiogenesis. Increased serum VEGF levels may be associated with poor prognosis in patients with non-small cell lung(More)
Interferon (IFN)-gamma plays a pivotal role in protective immunity against Mycobacterium tuberculosis. Elevations of IFN-gamma have been found in the affected lung and bloodstream of patients with pulmonary tuberculosis. In the present study, we aimed to investigate the role of serum IFN-gamma level in the differential diagnosis of active and inactive(More)
Epidermal growth factor receptor (EGFR) has been implicated as a factor indicating tumour progression or as a prognostic factor in non-small cell lung cancer (NSCLC), in which its overexpression is often detected. The usefulness of identifying EGFR in serum from patients with NSCLC is controversial. This study was designed to identify serum EGFR levels in(More)
Metastatic non-small cell lung cancer (NSCLC) has a poor prognosis. Adrenal metastasis (AM), in NSCLC, are present in 5-10% of patients at initial presentation. Several case reports have shown that operation of isolated AM results in longer survival time. We describe a 55 year-old man with diagnosis of NSCLC with operable lung tumor and solitary AM treated(More)
We studied ADA and gamma interferon (gamma-IFN) levels in pleural fluid of 45 cases presenting with pleural effusion to the Ankara University School of Medicine Chest Diseases Hospital between September 2001 and September 2002. Fifteen patients had TB pleurisy, 20 patients had malignant pleurisy and 10 patients had transudative pleural effusion. The cut-off(More)
