INTRODUCTION/BACKGROUND Effective cancer biomarkers for early detection, prognosis, or therapy response prediction are urgently need in metastatic RCC. M30 and M65 are released during apoptotic cell death and precisely reflect epithelial tumor cell death. The aim of this study was to determine the prognostic value of plasma M30 and M65 levels in predicting(More)
Several nanoparticle platforms are currently being developed for applications in medicine, including both synthetic materials and naturally occurring bionanomaterials such as viral nanoparticles (VNPs) and their genome-free counterparts, virus-like particles (VLPs). A broad range of genetic and chemical engineering methods have been established that allow(More)
BACKGROUND The aim of this study was to determine the tendency to use complementary/alternative medicine (CAM) by patients with cancer in Turkey, and to compare sociodemographic and medical characteristics, perceptions, and quality of life of users and nonusers of CAM. METHODS A total of 1060 cancer patients were asked to complete a questionnaire about(More)
PURPOSE Glioblastoma multiforme (GBM) is the most common brain tumor in adults and has a very aggressive course. Median survival is as short as 2 years with standard treatment (chemoradiotherapy followed by adjuvant temozolomide). The purpose of this study was to determine the contribution of low molecular weight heparin (LMWH) addition to concomitant(More)
Trace elements are essential components of biological structures, but they can be toxic at concentrations beyond those necessary for their biological functions. In the present study, groups of 35 patients with bladder cancer and 34 healthy volunteer controls were measured for trace elements using a furnace atomic absorption spectrophotometer. Serum levels(More)
BACKGROUND The aim was to evaluate the characteristics of Wilms' tumor and the results of combined modality treatment obtained in our center in Turkey. METHODS From January 1978 to December 1996, 106 patients with Wilms' tumor were diagnosed. Of these 106 patients, 61 were male and 45 were female (M/F = 1,35); the median age at diagnosis was 39 months.(More)
OBJECTIVE Therapy targeted against the vascular endothelial growth factor pathway is a standard of care for patients with metastatic renal cell carcinoma. This study assessed the response rates and toxicity profiles of sunitinib on a continuous once-daily dosing regimen in Turkish patients with metastatic renal cell carcinoma. METHODS Between April 2006(More)
BACKGROUND It is well known that survivors of acute lymphoblastic leukemia (ALL) show a tendency to become overweight. Cranial irradiation (CRT), is considered to be the primary risk factor for development of obesity. AIMS The aim of our study was to evaluate body mass index (BMI) and serum leptin levels in survivors of childhood ALL. METHODS Subjects(More)
Nanomaterial-based carrier systems hold great promise to deliver therapies with increased efficacy and reduced side effects. While the state-of-the-art carrier system is a sphere, recent data indicate that elongated rods and filaments have advantageous flow and margination properties, resulting in enhanced vascular targeting and tumor homing. Here, we(More)
OBJECTIVE Determination of psychological problems will shed light on the terms of solution and provide support to patients about these problems will ensure the patients' coherence to the treatment and will enhance the benefits they receive from treatment. In this study, we aimed to determine these psychosocial problems and the interactions with each other(More)
