Comparative genomic hybridization (CGH) was used to detect copy number changes of DNA sequences in the Ewing family of tumours (ET). We analysed 20 samples from 17 patients. Fifteen tumours (75%) showed copy number changes. Gains of DNA sequences were much more frequent than losses, the majority of the gains affecting whole chromosomes or whole chromosome(More)
Osteolytic lesions and pathological fractures are common in multiple myeloma. Because clodronate inhibits osteoclastic resorption, we did a randomised, controlled trial in 350 patients from 23 hospitals. All patients received standard melphalan-prednisolone, and were randomised to receive clodronate 2.4 g daily or placebo for 24 months. The proportion of(More)
Our aim was to identify chromosomal regions that are likely to harbor previously unknown genes with an important role in the genesis of osteosarcoma. Comparative genomic hybridization was used to screen for losses and gains of DNA sequences along all chromosome arms in 11 tumors. Extensive genetic aberrations, with an average of 11 changes/tumor (range,(More)
Type I collagen is the main collagen type found in mineralised bone. Specific immunoassays for PICP (carboxyterminal propeptide of type I procollagen) and ICTP (cross-linked carboxyterminal telopeptide region of type I collagen) allow simultaneous assessment of the synthesis and degradation of type I collagen in serum samples, respectively. Our aim was to(More)
PURPOSE The aim of this study was to determine whether serum matrix metalloproteinase (MMP) -2 and MMP-9 levels could predict overall and disease-free survival in primary node-positive breast cancer. EXPERIMENTAL DESIGN MMP-2 and MMP-9 levels were quantitatively measured in serum after surgery from 133 patients with primary node-positive breast cancer(More)
5-Fluorouracil (5-FU)-based chemotherapy is frequently associated with diarrhoea. We compared two 5-FU-based regimens and the effect of Lactobacillus and fibre supplementation on treatment tolerability. Patients diagnosed with colorectal cancer (n=150) were randomly allocated to receive monthly 5-FU and leucovorin bolus injections (the Mayo regimen) or a(More)
The effect of clodronate on bone mineral density (BMD) was studied in 121 post-menopausal breast cancer women without skeletal metastases. In addition, two antioestrogens, tamoxifen and toremifene, were compared in their action on bone mineral density. Patients were randomized to have an adjuvant antioestrogen treatment either 20 mg of tamoxifen or 60 mg of(More)
Thirty-four normocalcaemic women with multiple osteolytic bone metastases from breast cancer were randomly allocated to treatment with disodium dichloromethylene diphosphonate (Cl2MDP) 1600 mg/day orally (17) or placebo (17) for 3-9 months. Fasting urinary hydroxyproline/creatinine and calcium/creatinine ratios declined in the Cl2MDP group but not in the(More)
Two hundred and eleven patients with node-positive stage II and III breast cancer were treated with eight cycles of adjuvant chemotherapy comprising cyclophosphamide, doxorubicin and oral ftorafur (CAFt), with and without tamoxifen. All patients had undergone radical surgery, and 148 patients were treated with post-operative radiotherapy in two randomized(More)
Thirty-six patients with bone metastases included in a trial of supportive calcitonin on the treatment response to systemic therapy were monitored by conventional radiography, conventional indicators of bone metabolism [alkaline phosphatase (AP), osteocalcin (gla), urinary hydroxyproline excretion (OHP), urinary calcium (uCa), serum calcium (sCa)] and(More)
