BACKGROUND Familial, non-medullary thyroid carcinoma is clinically more aggressive than the sporadic form. We wanted to find out whether papillary thyroid microcarcinoma also occurs in a familial pattern, and, if so, to identify specific clinical and prognostic features. METHODS We reviewed the clinical records of 119 patients with papillary thyroid(More)
We have demonstrated that interferon-α2-recombinant (IFNα) at growth inhibitory concentrations enhances the expression and signalling activity of the epidermal growth factor receptor (EGF-R) in human epidermoid carcinoma KB cells. Here we report that KB cells exposed to IFNα underwent apoptotic cell death and this effect was antagonized by EGF. We have also(More)
Overexpression of the gene encoding phosphoprotein enriched in astrocytes 15 (PEA15), also known as phosphoprotein enriched in diabetes (PED), causes insulin resistance and diabetes in transgenic mice and has been observed in type 2 diabetic individuals. The aim of this study was to investigate whether PEA15 overexpression occurs in individuals at high risk(More)
OBJECTIVE Glucocorticoid excess is widely recognized as one of the most important causes of bone loss. The mechanism of glucocorticoid-induced osteoporosis is presumably multifactorial, and consists of the loss of organic and non-organic compounds. Efforts have been made to develop simple physical methods for the assessment of bone tissue for the screening(More)
Skeletal metastases from thyroid cancer are poorly responsive to medical or radioiodine treatment. Bone destruction in skeletal metastases results from osteoclast-induced bone resorption. Therefore, a new approach in the therapy of bone metastases consists in using aminobisphosphonates, such as pamidronate, which are potent inhibitors of osteoclastic(More)
To investigate the effects of long term thyroid hormone suppressive therapy on the heart, 20 patients were evaluated by noninvasive techniques. Of them, 10 were athyreotic after surgery for differentiated thyroid cancer, and 10 had diffuse or nodular goiter. The mean age of the group was 39 +/- 11 yr. Twenty age- and sex-matched subjects served as controls.(More)
Ret is a receptor tyrosine kinase involved in several neoplastic and developmental diseases affecting the thyroid gland and tissues of neuroectodermal origin. Different ret mutations are associated with different disease phenotypes. Gain-of-function of ret is caused by gene rearrangements in thyroid papillary carcinomas and by point mutations in multiple(More)
We present a prospective study on the long-term efficacy of percutaneous ethanol injection (PEI) treatment of a large series of symptomatic thyroid cystic nodules (STCN). Ninety-eight patients (72 females and 26 males) were treated. The mean basal volume of the STCN was 35.3 mL. In 92 of 98 patients PEI treatment induced a greater than 50% nodule shrinkage,(More)
Medullary thyroid carcinomas (MTC) occur sporadically or as part of inherited multiple endocrine neoplasia (MEN) type 2 syndromes. To recognize misdiagnosed familial cases and to establish the frequency of somatic mutations, a series of 50 patients, clinically diagnosed with sporadic MTC, were analyzed for mutations in the RET proto-oncogene. The clinical(More)
In the past years, the attention of scientists has focused mainly on the study of the genetic information and alterations that regulate eukaryotic cell proliferation and that lead to neoplastic transformation. All therapeutic strategies against cancer are, to date, directed at DNA either with cytotoxic drugs or gene therapy. Little or no interest has been(More)
