PURPOSE It has been hypothesized that tumors with high interstitial fluid pressure (IFP) and/or hypoxia respond poorly to chemotherapy (CT) because of poor drug delivery. Preclinical studies have shown that paclitaxel reduces the IFP and improves the oxygenation (pO(2)) of tumors. Our aim is to evaluate the IFP and pO(2) before and after neoadjuvant CT(More)
OBJECTIVE The objective of this study is to evaluate the role of high resolution ultrasonography (US) and endoscopic ultrasound (EUS)-elastography in predicting malignant lymphadenopathy. PATIENTS AND METHODS This prospective study included 88 patients who underwent EUS or US examination of different groups of lymph nodes (LNs). The classification as(More)
BACKGROUND Ultrasonography is considered useful to distinguish between solid and cystic thyroid nodules and to stratify a nodule's risk of cancer as low, medium, or high. Ultrasound (US) elastography has been applied to study the hardness/elasticity of nodules to differentiate malignant from benign lesions. Elastography possibly can solve the dilemma in(More)
