Esta pesquisa integra dissertação mestrado andamento, intitulada Trajetória da Inclusão Estudantes (TEA): Experiências na Transição entre Classes Inclusivas Especiais, que busca aprofundar a compreensão sobre desafios, as...
Abstract Effective treatment for advanced and metastatic tumors remains a major clinical challenge. Chemotherapy has an objective response rate of 40%, reliable predictive biomarkers to guide are lacking. Global implementation Functional Precision Oncology (FPO) offers promising, personalized approach predicting tumor response, with potential improve patient outcomes, optimize resource use, promote equity across diverse geographic regions. This study aims establish validate functional...
To report oncological cases (excluding those related to breast cancer) for which radioguided surgery has been used in combination with the Radioguided Occult Lesion Localization technique. enables a surgeon identify lesions or tissues that have preoperatively marked radioactive substances. The technique widely sentinel lymph node and occult patients cancer. However, few studies reported use of this non-breast cancer pathologies. In all cases, injection Technecium-99m sulfur colloid was...
The adrenal glands are an important site of both primary and secondary disease processes. Image-guided percutaneous biopsy the gland is accurate safe alternative to surgical biopsy. This procedure most often performed in patients with a suspicion metastatic where pathological diagnosis plays role staging defining therapy. There many different approaches performing under CT guidance such as anterior transhepatic/transpancreatic, lateral transhepatic/transplenic or posterior...
Most diagnostic imaging centers ask patients to fast for 4-6 hours before contrast-enhanced CT. Previous studies have shown that prolonged fasting can be harmful. In addition, manufacturers of contrast agents claim there is no special preparation needed examination. The aim this study was evaluate the effects preparative on CT at a cancer center.Outpatients (n = 3206) were prospectively evaluated and randomly assigned two groups: 1619 in group 1 fasted least 4 examination, whereas 1587 2...
Abstract Purpose: The purpose of this randomized, prospective study was to evaluate the effect three preparation types on abdominal sonographic examination quality and patient acceptance. Methods: Examinations were performed 611 patients in imaging department a referral oncology center. Patients divided into groups: with fasting, water, laxatives, antiflatulents (Group I), alone II), or fasting water III). evaluated both objectively through grades subjectively impressions. Statistical...

Abstract Tumor DNA has been detected in body fluids of cancer patients. Somatic tumor mutations are being used as biomarkers to monitor chemotherapy response a minimally invasive tool. In this study, we evaluated the potential tracking somatic free plasma and urine collected from Wilms (WT) patients for monitoring treatment response. is pediatric renal resulting cell differentiation errors during nephrogenesis. Its mutational repertoire not completely defined. Thus, identifying tissue DNA,...
Conformal external radiotherapy aims to improve tumor control by boosting dose, reducing morbidity and sparing healthy tissues. To meet this objective careful visualization of the adjacent areas is required. However, one major issues be solved in context volumetric definition targets. This study proposes compare gross volume lung tumors as delineated specialized radiologists radiotherapists a cancer center. Chest CT scans total 23 patients all with non-small cell cancer, not submitted...
Objective: To describe a technique for CT-guided biopsy based on PET/CT findings and to evaluate the indications results of in cancer patients. Methods: We evaluated all patients receiving percutaneous biopsies whose indication was at an oncology reference center from October 2009 December 2010. The images were side by with noncontrast CT identify lesion or area interest be biopsied. Biopsies guided needle directed metabolic activity identified examination performed before procedure....
OBJETIVO: Avaliar a eficácia da biópsia percutânea por agulha grossa (BPAG) de tumores partes moles guiada tomografia computadorizada (TC), em relação ao sucesso na obtenção amostra para análise, e comparar o diagnóstico BPAG com resultado anatomopatológico peça cirúrgica, quando disponível.

RESULTADOS: Das biópsias realizadas, foi possível...
To evaluate (18)F-fluorodeoxyglucose ((18)F-FDG) uptake on positron emission tomography-computed tomography (PET-CT) and serum levels of different cytokines matrix metalloproteinases (MMPs) in patients with Takayasu arteritis (TA) associations disease activity.Serum tumor necrosis factor-α (TNF-α), interleukin (IL)-2, IL-6, IL-8, IL-12, IL-18, MMP-3 MMP-9 were measured 36 TA controls. Maximum standard value (SUVmax) (18)F-FDG arterial walls was determined by PET-CT scans. classified as...
subcutaneous emphysema is superimposed on thoracic structures X-rays taken at the bedside. PROCEDUREIn patients with pneumomediastinum, treatment should be started immediately, before there clinical evidence of cardiac tamponade or increased intracranial pressure.Invasive surgical techniques classically described for pneumomediastinum include tracheostomy, sternotomy, and mediastinotomy, all which carry high risks complications (hemothorax, infection, inadvertent injury to neighboring...
Pulmonary tumor thrombotic microangiopathy is a rare complication of malignant diseases. The diagnosis extremely difficult and most often performed after death.
