PURPOSE Chemotherapy before resection of hepatic colorectal metastases (CRM) may cause hepatic injury and affect postoperative outcome. PATIENTS AND METHODS Four hundred six patients underwent hepatic resection of CRM between 1992 and 2005. Pathologic review of the nontumorous liver was performed using established criteria for steatosis, steatohepatitis,(More)
BACKGROUND A single flexible sigmoidoscopy at around the age of 60 years has been proposed as an effective strategy for colorectal cancer (CRC) screening. METHODS We conducted a randomized controlled trial to evaluate the effect of flexible sigmoidoscopy screening on CRC incidence and mortality. A questionnaire to assess the eligibility and interest in(More)
BACKGROUND A single sigmoidoscopy examination at around age 60 years has been proposed as a cost-effective strategy to prevent colorectal cancer. A multicenter randomized controlled trial, the SCORE trial, is in progress in Italy to estimate the impact of this strategy on colorectal cancer incidence and mortality and the duration of the protective effect.(More)
Adenomas that contain early invasive carcinoma (ACIC) represent the earliest form of clinically relevant cancer of the colorectum in most patients. In order to assess the incidence of nodal metastases of ACIC, we studied 31 patients in whom the colon was resected after endoscopic polypectomy (EP) done from 1975 to 1987. We also reviewed the pathologic(More)
PURPOSE The malignant polyp carries a significant risk of lymphohematic metastasis and mortality. Clinical usefulness of histologic risk factors is still controversial. The study was designed to compute the association between the main histologic risk factors and the occurrence of unfavorable outcomes in patients with malignant polyps. METHODS A MEDLINE(More)
UNLABELLED Only a fraction of patients with metastatic colorectal cancer receive clinical benefit from therapy with anti-epidermal growth factor receptor (EGFR) antibodies, which calls for the identification of novel biomarkers for better personalized medicine. We produced large xenograft cohorts from 85 patient-derived, genetically characterized metastatic(More)
OBJECTIVE Conventional therapies are still unsuccessful in patients with carcinoma arising from the biliary tract. Somatic mutations of the epidermal growth factor receptor (EGFR) gene and the activation of its downstream pathways predict the sensitivity to small-molecule inhibitors in non-small cell lung carcinoma. Therefore, we analyzed EGFR mutations and(More)
Population-based screening for early detection and treatment of colorectal cancer (CRC) and precursor lesions, using evidence-based methods, can be effective in populations with a significant burden of the disease provided the services are of high quality. Multidisciplinary, evidence-based guidelines for quality assurance in CRC screening and diagnosis have(More)
To identify gene expression changes in melanocytic lesions, biopsies from 18 common nevi (CMN), 11 dysplastic nevi (DN), 8 radial and 15 vertical growth phase melanomas (RGPM, VGPM), and 5 melanoma metastases (MTS) were analyzed using whole genome microarrays. The comparison between CMN and RGPM showed an enrichment of Gene Ontology terms related to inter(More)
It is well known that adenomas represent the morphologically categorised precursor of the vast majority of colorectal cancers. Only few adenomas actually develop invasive cancer (progressive adenomas), although every adenoma has the capacity of malignant evolution. Most adenomas stabilise their progression or even regress. Easily identifiable but widely(More)
