BACKGROUND Patients with advanced midgut neuroendocrine tumors who have had disease progression during first-line somatostatin analogue therapy have limited therapeutic options. This randomized, controlled trial evaluated the efficacy and safety of lutetium-177 (177Lu)-Dotatate in patients with advanced, progressive, somatostatin-receptor-positive midgut(More)
BACKGROUND We previously selected a panel of 3 breast cancer biomarkers (BC1, BC2, and BC3) from serum samples collected at a single hospital based on their collective contribution to the optimal separation of breast cancer patients and noncancer controls by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS). The(More)
A large number of markers have been proposed for breast cancer, but among them only CA 15.3, CEA and cytokeratins (i.e. TPA, TPS and Cyfra 21.1) are currently used in clinical practice. Serum marker levels reflect tumour burden and for this reason they are not sensitive enough to be used for screening and early diagnosis of primary breast cancer. By(More)
BACKGROUND The RET proto-oncogene encodes a receptor tyrosine kinase. RET oncogenes arise through sporadic and inherited gene mutations and are involved in the etiopathogenesis of medullary thyroid carcinoma, a cancer that responds poorly to conventional chemotherapy. Medullary thyroid carcinoma is a component of multiple endocrine neoplasia type 2 or MEN2(More)
AIM Since the second half of the 1980s, (131)I-MIBG has been widely used for treatment of patients with malignant pheochromocytoma. In 1991, at the International Meeting in Rome, it was agreed that (131)I-MIBG therapy induces significant tumor responses in about 30-50% of cases, long-term stabilization of disease in several cases and significant reduction(More)
Osteoprotegerin (OPG) is a potent antiresorptive molecule that binds NF-kappaB ligand, the final effector for osteoclastogenesis. OPG production is regulated by a number of cytokines and hormones. Osteopontin (OPN) is a secreted adhesive glycoprotein involved in tumour angiogenesis, and also a non-collagenous protein involved in bone turnover. OPN serum(More)
BACKGROUND Survival rates are reportedly excellent for papillary thyroid carcinomas (PTCs) in childhood/adolescence, despite their strong tendency to spread. The aim of this study was to verify this assumption in a single-institution series spanning a 30-year period with a very long follow-up. PROCEDURE From 1968 to 2001, 74 cases of thyroid carcinoma(More)
We have previously documented that ursodeoxycholic acid exerts a beneficial effect on liver function and bile acid metabolism in patients with cystic fibrosis. We hypothesized that the mechanism of action may be related in part to the choleretic properties of the administered bile acid. We therefore compared hepatobiliary scintigraphic images obtained(More)
Differentiated thyroid cancer (DTC) is the most common endocrine cancer and its incidence has increased in recent decades. Initial treatment usually consists of total thyroidectomy followed by ablation of thyroid remnants by iodine-131. As thyroid cells are assumed to be the only source of thyroglobulin (Tg) in the human body, circulating Tg serves as a(More)
AIM Neuroendocrine tumors over-express somatostatin receptors and literature data have demonstrated the efficacy of the peptide receptor radionuclide therapy with somatostatin analogues labelled with high activities of b-emitting radioisotopes, such as (90)Y and (177)Lu. Yttrium-90 is a pure high energy b-emitter while (177)Lu is a b/g emitter of medium(More)
