uric acid/sarcoma

BACKGROUND Recent evidence indicates toward a role of uric acid (UA) as a potential antioxidant. Elevated UA levels were shown to be associated with better survival in various malignancies. The aim of the present study was to evaluate the prognostic relevance of pre-operative UA levels on

Myeloid sarcoma (chloroma, granulocytic sarcoma, or extramedullary myeloid tumour) is an extramedullary mass forming neoplasm composed of myeloid precursor cells. It is usually associated with myeloproliferative disorders but very rarely may precede the onset of leukemia. Here, we are presenting a

BACKGROUND Gout is a metabolic disease by deposition of uric acid crystals, which undertakes joint and soft tissue in both acute and chronic stages. Is a rare event the onset of a tumor in the site of the lesion. OBJECTIVE To present a rare case of association between sarcoma and tophi. METHODS 83

BACKGROUND Figitumumab is a fully human IgG2 monoclonal antibody targeting the insulin-like growth-factor-1 receptor (IGF-1R). Preclinical data suggest a dependence on insulin-like growth-factor signalling for sarcoma subtypes, including Ewing's sarcoma, and early reports show antitumour activity of

Peroxynitrite (ONOO(-)), which is generated from nitric oxide (NO) and superoxide anion (O(2)(.-)) under pathological conditions, plays an important role in pathophysiological processes. Activation of matrix metalloproteinases (MMPs) contributes to tumor angiogenesis and metastasis. NO mediates the

Insidious and progressive right heart failure of obscure origin warrants differential diagnosis of primary sarcoma of the pulmonary artery in patients of both sexes and 20 years of age and older. We report a case of primary leiomyosarcoma of the pulmonary truncus in a 67 years old woman. She had

Inhibition of conversion from IMP to uric acid, which interferes with both spectrophotometric and radioisotopic assays of IMP dehydrogenase, by addition of allopurinol (0.1 mM), an inhibitor of xanthine oxidase, to the incubation system made it possible to determine the enzyme activity in crude

OBJECTIVE Hemorrhagic cystitis is a common complication with chemotherapeutic alkylating agents. We investigated the possible prognostic factors of cyclophosphamide-induced hemorrhagic cystitis in children. METHODS Medical records of children (< 18 years old) with cyclophosphamide-related

Two cases of hypouricemia in association with malignant diseases are presented. One patient had metastatic breast cancer and the other an undifferentiated retroperitoneal sarcoma of the childhood. Uric acid renal handling was studied with the pyrazinamide and benzbromarone tests. Both patients had

This case depicts an unusual presentation of gout, which could be mistaken for sarcoma. The radiographic and MRI findings suggest gout whereas the CT appearance is most specific. Therefore, CT should be considered when MRI demonstrates low to intermediate T2 signal in a heterogeneously enhancing

We have been able to detect soluble interleukin-2 receptors (IL-2R) in pretreatment sera from 80 patients with undifferentiated lymphoma (predominantly Burkitt's lymphoma) and lymphoblastic lymphoma. The demonstration of IL-2R in lymphoma-derived cell lines by immunoprecipitation and direct staining
