BACKGROUND Recurrent nerve injury is 1 of the most important complications of thyroidectomy. During the last decade, nerve monitoring has gained increasing acceptance in several centers as a method to predict and to document nerve function at the end of the operation. We evaluated the efficacy of a nerve monitoring system in a series of patients who(More)
BACKGROUND Metalloproteinase 2 (MMP-2) and tissue inhibitor of metalloproteinase 2 (TIMP-2) participate in the degeneration of the extracellular matrix and are associated with carcinogenesis. MMP-2 is one of the main metalloproteinases active in neoplasia and is a marker of the malignant phenotype. Since the biological behavior of medullary thyroid(More)
BACKGROUND Clinical and pathologic examinations cannot always provide a prognosis for patients with medullary thyroid carcinoma. Membrane type 1 matrix metalloproteinase (MT1-MMP) can act directly on carcinogenesis and takes part in 1 of the processes of metalloproteinase 2 activation, an enzyme related to prognostic impairment of patients with such tumor.(More)
OBJECTIVES To develop an index for the ratio of metalloproteinase 2 (MMP-2) to its tissue inhibitor (TIMP-2) in immunostained medullary thyroid carcinoma specimens and to correlate it with clinical and pathologic prognostic factors. Metalloproteinases, enzymes related to the degradation of the extracellular matrix, take part in carcinogenesis and have been(More)
The aim is to determine if tumor thickness is a risk factor related to the development of early recurrences in surgically treated oral cavity squamous cell carcinoma (SCC). Retrospective cohort study conducted at Instituto do Câncer do Estado de São Paulo (ICESP). Fifty-seven patients with oral cavity SCC (excluding lip tumors and patients previously(More)
UNLABELLED OBJECTIVES AND INTRODUCTION: Medullary thyroid carcinoma, a neoplasia of intermediate prognosis and differentiation, does not always respond predictably to known treatments. This study aimed to correlate the clinical progression of surgically treated patients with clinical and pathological data. METHODS A total of 53 patients were followed for(More)
Objective The aim of the present study was to describe the epidemiologic data, histological type, treatment and follow-up of the 811 patients treated for thyroid cancer in Instituto do Câncer do Estado de São Paulo (ICESP) over 5 years. Materials and methods Retrospective analyses of electronic chart information. Results There were 679 cases (83.7%) of(More)
