PURPOSE We study the potential diagnostic use of urinary bladder cancer antigen, CYFRA 21-1 and NMP22*; for evaluating symptomatic patients who present with microscopic hematuria and are at risk for bladder cancer. MATERIALS AND METHODS Urinary tumor markers were determined in 187 samples from 112 patients symptomatic of bladder cancer (group 1), and 75(More)
Hepatocellular carcinoma (HCC) exhibits variable features on Magnetic Resonance (MR) images. In this study, the correlations between MR patterns of HCC and histopathologic findings are investigated. Fifty patients with HCCs were studied with MR at 0.5 T. All neoplastic lesions were subsequently submitted to biopsy: structural pattern, tumor grading(More)
BACKGROUND We evaluated the potential role of serial preinstillation levels of several interleukins, TNFalpha and urinary tumor markers to monitor patients with bladder cancer receiving intravesical BCG. PATIENTS AND METHODS 121 urine samples were collected from: patients with bladder cancer treated with BCG (group 1); patients with bladder cancer(More)
OBJECTIVES To evaluate the diagnostic characteristics of the urinary measurement of cytokeratin tissue polypeptide-specific antigen (TPS) for the detection of bladder cancer. METHODS Three hundred thirty-five individuals in five groups were studied: group 1, subjects with microhematuria under suspicion for primary bladder cancer; group 2, patients being(More)
Toxoplasma gondii infection was investigated in 14 AIDS patients with neurological involvement who showed clinical and computer tomographic scan signs suggestive of toxoplasmic encephalitis or extraneuronal localization suggestive of toxoplasmic infection. Blood, lung secretion (bronchoalveolar lavage and/or induced sputum sample) and cerebral spinal fluid(More)
