The introduction of multidrug therapy (WHO/MDT)-composed by the drugs dapsone, clofazimine and rifampicin has enabled the cure of Hansen's disease, however, the adverse effects of these drugs were not given priority by the health team. Aiming to determine MDT's adverse effects' magnitude and relate them to the non-adhesion of patients to the treatment, a(More)
BACKGROUND AND PURPOSE Intensity-modulated radiation therapy (IMRT) provides the possibility of dose-escalation with better normal tissue sparing. This study was performed to assess whether IMRT can improve clinical outcomes when compared with two-dimensional (2D-RT) or three-dimensional conformal radiation therapy (3D-CRT) in patients with head and neck(More)
The role of radiotherapy (RT) in the treatment of urinary bladder cancer has undergone several modifications along the last decades. In the beginning, definitive RT was used as treatment in an attempt to preserve the urinary bladder; however, the results were poor compared to those of radical surgery. Recently, many protocols have been developed supporting(More)
BACKGROUND Clinically localized prostate cancer may be treated by different approaches of radiation therapy. The aim of this study was to report the results of disease control and toxicity in patients with clinically localized prostate cancer treated with high dose IMRT alone with 1 cm PTV posterior margin. METHODS From September 2001 to April 2008, 140(More)
The purpose of the study is to evaluate the effects of pharmacological and non-pharmacological topical controls in the prevention of radiation dermatitis. Relevant clinical trials were identified through electronic searching databases CINAHL, CENTRAL, LILACS, PubMed, Scopus, and Web of Science. Handsearching and gray literature searches were also performed(More)
There are many available options for prostate cancer treatment, including active surveillance, surgery, brachytherapy and external beam radiotherapy. Based on a radiobiological rationale, which considers the prostate tumor as a low α/β tumor, the use of higher and fewer fractions to prostate cancer external beam radiotherapy treatment has been proposed.(More)
OBJECTIVE The addition of androgen deprivation therapy (ADT) to conventional radiation therapy improves overall survival (OS) in intermediate- and high-risk prostate cancer. The benefit of ADT to added to dose-escalated radiotherapy is less clear. The aim of this study was to report disease control outcomes and to identify prognostic variables associated(More)
The Guidelines Project, an initiative of the Brazilian Medical Association, aims to combine information from the medical field in order to standardize procedures to assist the reasoning and decision-making of doctors. The information provided through this project must be assessed and criticized by the physician responsible for the conduct that will be(More)
For early-stage lung cancer, the treatment of choice is surgery. In patients who are not surgical candidates or are unwilling to undergo surgery, radiotherapy is the principal treatment option. Here, we review stereotactic body radiotherapy, a technique that has produced quite promising results in such patients and should be the treatment of choice, if(More)
