Poorly differentiated (PD) thyroid carcinomas lie both morphologically and behaviorally between well-differentiated and undifferentiated (anaplastic) carcinomas. Following the original description of this entity, different diagnostic criteria have been employed, resulting in wide discrepancies and confusion among pathologists and clinicians worldwide. To(More)
BACKGROUND We tested the hypothesis that ovarian cancers associated with germ-line mutations of BRCA1 have distinct clinical and pathological features as compared with sporadic ovarian cancers. METHODS We reviewed clinical and pathological data on patients with primary epithelial ovarian cancer found to have germ-line mutations of BRCA1. Survival among(More)
A population-based case-control interview study of thyroid cancer (159 cases and 285 controls) was conducted in Connecticut. Prior radiotherapy to the head or neck was reported by 12% of the cases and 4% of the controls [odds ratio (OR) = 2.8; 95% confidence interval = 1.2-6.9]. Risk was inversely related to age at irradiation and was highest among children(More)
High-grade transformation of adenoid cystic carcinoma (ACC) (previously referred to as dedifferentiation) is a rare phenomenon that does not fit into the traditional ACC grading schemes. The importance and minimal criteria for distinction from solid (grade III) ACC are not well established. We report 11 new cases and review the literature to further define(More)
A case-control study to identify risk factors for epithelial ovarian cancer was undertaken among women in the age group 45-74 years who had been admitted to seven hospitals in Connecticut between July, 1977, and March, 1979. Characteristics that were found to increase the risk of epithelial ovarian cancer included being white, never having been pregnant,(More)
The thyroid fine-needle aspiration (FNA) diagnosis of "follicular neoplasm" does not differentiate between a benign and malignant tumor. Often cases diagnosed as "follicular or Hürthle-cell neoplasm" undergo surgical excision for further characterization. The aim of this study was to identify clinical features that may help in predicting malignancy in(More)
BACKGROUND Approximately 15 to 30% of thyroid nodules evaluated by means of fine-needle aspiration are not clearly benign or malignant. Patients with cytologically indeterminate nodules are often referred for diagnostic surgery, though most of these nodules prove to be benign. A novel diagnostic test that measures the expression of 167 genes has shown(More)

Papillary thyroid carcinoma (PTC) is clinically heterogeneous. Apart from an association with ionizing radiation, the etiology and molecular biology of PTC is poorly understood. We used oligo-based DNA arrays to study the expression profiles of eight matched pairs of normal thyroid and PTC tissues. Additional PTC tumors and other tissues were studied by(More)
Forty-seven cases of malignant mixed tumor (MMT) arising in major and minor salivary glands are presented. By definition, all these lesions contained both a benign mixed tumor (BMT) as well as a malignant neoplasm, usually a poorly differentiated carcinoma. In some cases, the carcinoma developed in a previously untreated salivary gland mass which was known(More)
Mutations in the MEN1 gene are associated with the multiple endocrine neoplasia syndrome type 1 (MEN1), which is characterized by parathyroid hyperplasia and tumors of the pituitary and pancreatic islets. The mechanism by which MEN1 acts as a tumor suppressor is unclear. We have recently shown that menin, the MEN1 protein product, interacts with mixed(More)
