Glomerular filtration rate (GFR) was evaluated in 32 Wilms' tumour survivors (WTs) a cross-sectional study using 99 Tc-diethylene triamine pentaacetic acid (99 Tc-DTPA) clearance, the Schwartz formula, new equation for chronic kidney disease (CKD), cystatin C serum concentration and Filler formula. Kidney damage established by beta-2-microglobulin (B-2-M) albumin urine excretion, sediment ultrasound examination. Blood pressure measured. No differences were found between mean GFR Tc-DTPA CKD...

In recent years, researchers have been paying special attention to the tumor microenvironment (TME). One of most important factors contributing development and progression cancer is destruction elements extracellular matrix (ECM). The substances involved in regulating degradation process are metalloproteinases (MMPs) their inhibitors (TIMPs). cell migration, chemokines secreted by target tissues, as well profile chemokine receptors presented on cells, play a key role. work, five components...

This study presents a unique series of malignant supratentorial gliomas in children previously cured from non-CNS primary cancer. On neuroimaging these tumors were not specific, so the patients suspected cerebral recurrence their neoplasm: leukemia four and sarcoma one child. Histologically, group contained glioblastomas anaplastic astrocytoma. Three underwent neurosurgical resection, while other two stereotactic diagnostic biopsy only. Despite combined oncological treatment, died during 20...
