INTRODUCTION Castleman's disease (CD) is a rare disease with unknown etiology and is clinically associated with lymph nodes enlargement. Primary axillary localization of CD represents 2% of the cases. CD rarely occurs in the breasts. PRESENTATION OF CASE We herein describe a rare case of CD that initially presented in the breast intramammary lymph node(More)
BACKGROUND Adjuvant chemoradiotherapy (CRT) is the standard treatment in Western countries for gastric cancer patients submitted to curative resection. However, the role of adjuvant CRT in gastric cancer treated with D2 lymphadenectomy has not been well defined. METHODS We conducted a retrospective study in patients with stage II to IV gastric(More)
BACKGROUND There is no consensus about the prognostic role of HER2 expression and that of other members of the EGFR family in gastric cancer patients. The aim of this study was to evaluate the prognostic value of the EGFR family in gastric cancer. METHODS This retrospective study included 201 patients with gastric and esophagogastric junction(More)
OBJECTIVE to evaluate natural evolution of right diaphragmatic injury after the surgical removal of a portion from hemi diaphragm. METHODS the animals were submitted to a surgical removal of portion from right hemi diaphragm by median laparotomy. The sample consists of 42 animals being 2 animals from pilot project and 40 operated animals. And the(More)
Biosensors for early detection of cancer biomarkers normally depend on specific interactions between such biomarkers and immobilized biomolecules in the sensing units. Though these interactions are expected to yield specific, irreversible adsorption, the underlying mechanism appears not to have been studied in detail. In this paper, we show that adsorption(More)
OBJECTIVE Micronuclei (MN) are biomarkers that can be applied to buccal epithelial cells to assess populations occupationally exposed to potentially carcinogenic agents. Liquid-based cytology (LBC) is a way to improve and refine the results obtained by this test. STUDY DESIGN Exfoliated buccal cells were collected from 40 subjects (20 construction workers(More)
Lung cancer is the leading world cause of cancer-related death, in both genders, and smoking is the main etiological factor. The discovery of immune checkpoints corroborates the hypothesis that ligands presented in tumors modulate the mechanisms of carcinogenesis and the immune activity of tumor microenvironment. Among the most studied coregulatory(More)
BACKGROUND Breast conserving surgery (BCS) after neoadjuvant chemotherapy (NC) in patients with locally advanced breast cancer (LABC) is an infrequent procedure. In these patients the association with BCS and oncoplastic surgery (OS) is reported as a possible procedure in case-series, but there are limited case-control studies. METHODS A matched(More)
Testicular germ cell tumors (TGCT) are the most common malignant neoplasm in young men. DNA mismatch repair deficiency can lead to microsatellite instability (MSI), an important mechanism of genetic instability. A mutation of the BRAF gene has been implicated in the pathogenesis of several solid tumors and has recently become an important therapeutic(More)
