BACKGROUND The aim of this study was to assess the activity of pemetrexed in patients with advanced gastric cancer. PATIENTS AND METHODS Thirty-eight eligible patients (median age 60 years) received pemetrexed 500 mg/m(2) every 3 weeks. Since toxicity was considerable in the first six patients, the protocol was amended to supplement subsequent patients(More)
PURPOSE The aim of this trial was to evaluate the safety and efficacy of oxaliplatin and capecitabine (XELOX) in neuroendocrine tumours' (NETs) treatment. METHODS Forty patients (pts) with advanced NETs were treated. Of these, 13 had untreated poorly differentiated NETs, 27 had well-differentiated NETs in progression after somatostatin analogues. Patients(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)
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)
O(6)-methylguanine DNA methyltransferase (MGMT) gene promoter methylation plays an important role in colorectal carcinogenesis, occurring in about 30%-40% of metastatic colorectal cancer. Its prognostic role has not been defined yet, but loss of expression of MGMT, which is secondary to gene promoter methylation, results in an interesting high response to(More)
BACKGROUND The noninferiority of a 6-week dosing schedule of lanreotide Autogel (Lan ATG) at a dose of 120 mg compared with a 3-week dosing schedule of lanreotide microparticles (Lan MP) at a dose of 60 mg was investigated in patients with neuroendocrine tumors (NET). METHODS Patients who had sporadic, well differentiated NET with a low grade of(More)
Letrozole is an orally competitive aromatase inhibitor. This double-blind, randomised, multicentre trial was carried out to evaluate the endocrine effects of two doses of letrozole, 0.5 mg versus 2.5 mg orally daily, in postmenopausal advanced breast cancer patients progressing after tamoxifen. The pharmacokinetics of letrozole was also assessed. 46(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)
BACKGROUND Chromogranin A (CgA), neuron specific enolase (NSE), carcinoembryonic antigen (CEA), and urinary 5-hydroxyindole-3-acetic acid (5-HIAA) are the markers currently used in the diagnosis, prognosis, and follow-up of patients with neuroendocrine tumors (NETs). The authors examined the role of such biomarkers in a large series of patients with NETs.(More)
The ability of breast tumours to synthesize hormones is well recognized, and local production of sex steroids is thought to play a role in breast cancer growth. We measured the intratumour and circulating levels of testosterone, dihydrotestosterone (DHT) and oestradiol in 35 histologically confirmed carcinomatous mammary tissues obtained at breast surgery(More)
