BACKGROUND To evaluate the influence of radiotherapy on the selenium serum levels of breast cancer patients. PATIENTS AND METHODS This prospective study includes 209 breast cancer patients treated by external beam radiotherapy from December 2007 until August 2008. Plasma selenium concentrations were determined before and at the end of the radiotherapeutic(More)
OBJECTIVE To evaluate the relationship between two year PSA nadir (PSAn) after brachytherapy and biochemical recurrence rates in prostate cancer patients. MATERIALS AND METHODS In the period from January 1998 to August 2007, 120 patients were treated with iodine-125 brachytherapy alone. The results analysis was based on the definition of biochemical(More)
OBJECTIVES To assess the incidence and clinical parameters that could influence migration of seeds in localized prostate cancer patients treated by stranded versus loose sources by Iodine-125 brachytherapy. MATERIALS AND METHODS 100 patients were treated from January/1998 until December/2006. Age, PSA, clinical stage, Gleason, prostate volume, number of(More)
INTRODUCTION Critical patients present systemic inflammatory process that can be followed by decrease in plasma concentrations of antioxidant vitamins. OBJECTIVE [corrected] The aim of this study was to evaluate the effect of the supplementation of antioxidant vitamins in critical patients and their relation with lipid peroxidation. METHODS 23 patients(More)
OBJECTIVE To report the seven-year preliminary results of a single-center on brachytherapy with Iodine-125 seeds, used in combination with external beam radiotherapy in selected patients with localized prostate cancer (T1-T2). MATERIALS AND METHODS All 105 patients treated by brachytherapy with Iodine-125 seeds, from January/1998 to December/2004, were(More)
OBJECTIVE: To evaluate the therapies utilized in the authors’ institution for management of high-grade extremity sarcomas, analyzing the overall survival rates following multidisciplinary treatment. MATERIALS AND METHODS: Retrospective study developed in the period from 1993 to 2007 with 36 patients diagnosed with stages IIb/III, submitted to postoperative(More)
The use of the transoesophageal echocardiography (TEE) in the critically ill patient admitted to the general intensive care unit begins to turn out to be very important but it is still little spread. The full implementation of the echocardiography in the general intensive cares is compromised by the acoustic window. However, TEE can flyover this difficulty(More)
OBJECTIVE patients suffering systemic inflammatory response syndrome (SIRS) constitute a group susceptible to elevated levels of oxidative stress. This study's aim is to evaluate the state of oxidative stress and levels of serum retinol and β-carotene in these patients. METHODS forty-six patients were divided into 2 groups: those those without diet (G1;(More)
INTRODUCTION Several adverse effects of radiotherapy have been associated with the process of increased oxidative stress in the organism. In this context, vitamin A noteworthy for its important role in combating oxidative stress, in addition to its chemoprotective effect. OBJECTIVE To assess the serum levels of vitamin A (retinol and β-carotene) and their(More)
