A prospective study of 149 unselected incident cases of pancreatic adenocarcinoma and 146 ethnically-matched controls found no associations between GSTM1 (adjusted odds ratio (AOR) 1.14), GSTT1 (AOR: 1.19) and CYP1A1 (AOR: 1.08) polymorphisms and pancreatic cancer susceptibility. Smoking and drinking status did not affect results. These polymorphisms do not(More)
This study aims to evaluate our institution's experience with thyroidectomy for Graves' disease, with an emphasis on indications and long-term outcomes. The study cohort consisted of 103 patients (mean age 34.3 [+/-13.9] years), who underwent thyroidectomy for Graves' disease between 1991 and 2002. Clinical and follow-up data were obtained by retrospective(More)
BACKGROUND Thyroglossal duct cysts (TGDCs) are common in children but also present in adults. This study evaluates the preoperative management and postoperative outcomes in patients with a resected TGDC. METHODS A retrospective analysis was performed on patients with a surgically treated TGDC. Clinicopathologic variables and treatment outcomes were(More)
Susceptibility to pancreatic adenocarcinoma appears to be linked to germ-line mutations in genes causing various familial cancer syndromes. The objectives of this study were to estimate the proportion of unselected pancreatic cancer patients belonging to hereditary cancer syndrome families and to determine the frequency ofp16, BRCA1, BRCA2, hMSH2, and hMLH1(More)
Germ-line and somatic truncating mutations of the APC gene are thought to initiate colorectal tumor formation in familial adenomatous polyposis syndrome and sporadic colorectal carcinogenesis, respectively. Recently, an isoleucine-->lysine polymorphism at codon 1307 (I1307K) of the APC gene has been identified in 6%-7% of the Ashkenazi Jewish population. To(More)
BACKGROUND The purpose of this retrospective investigation was to evaluate the results of preoperative localization studies and intraoperative parathyroid hormone (IOPTH) assay in patients with primary hyperparathyroidism and double adenomas. STUDY DESIGN Twenty-one of 287 consecutive patients with primary hyperparathyroidism who had double adenomas(More)
In a hospital based case-control study of pancreatic cancer in Ontario and Quebec, a total of 174 incident pancreatic cancer cases and 136 healthy controls were compared for their family history of cancer. Information regarding the ages and sites of cancer was taken for 966 first-degree relatives of the cancer cases and for 903 first-degree relatives of the(More)
INTRODUCTION Previous work in a small, unselected series showed that up to 83% of breast carcinomas overexpress ECM1 by immunohistochemistry (IHC) and that tumors with lymph node metastases are more likely to be ECM1-positive. We sought to further evaluate ECM1 expression and its effect on prognosis in an unselected cohort of patients with breast cancer. (More)
BACKGROUND Mutations in the RET proto-oncogene cause multiple endocrine neoplasia type 2A (MEN2A), and prophylactic thyroidectomy has generally been recommended before the age of 5 years. Patients with codon 609 mutations develop MTC at a later age and therefore the timing of prophylactic thyroidectomy is less clear. We report a three-generation family with(More)
BACKGROUND Minimally invasive parathyroidectomy (MIP) has become increasingly popular for the treatment of patients with primary hyperparathyroidism (pHPT), and the specific techniques used vary from surgeon to surgeon. This strategy depends on preoperative localization tests, of which the MIBI scan is the most commonly used. This study details one(More)
