    The incidence of Cholangiocellular carcinoma (CCA) is increasing, due to a sharp increase of the intrahepatic form. Evidence-ascertained risk factors for CCA are primary sclerosing cholangitis, Opistorchis viverrini infection, Caroli disease, congenital choledocal cist, Vater ampulla adenoma, bile duct adenoma and intra-hepatic lithiasis. Obesity, diabetes, smoking, abnormal biliary-pancreatic junction, bilio-enteric surgery, and viral cirrhosis are emerging risk factors, but their role still needs to be validated. Patients with primary sclerosing cholangitis should undergo surveillance, even though a survival benefit has not been clearly demonstrated. CCA is most often diagnosed in an advanced stage, when therapeutic options are limited to palliation. Diagnosis of the tumor is often difficult and multiple imaging techniques should be used, particularly for staging. Surgery is the standard of care for resectable CCA, whilst liver transplantation should be considered only in experimental settings. Metal stenting is the standard of care in inoperable patients with an expected survival >4 months. Gemcitabine or platinum analogues are recommended in advanced CCA whilst there are no validated neo-adjuvant treatments or second-line chemotherapies. Even though promising results have been obtained in CCA with radiotherapy, further randomized controlled trials are needed. (C) 2010 Editrice Gastroenterologica Italiana S.r.l.

    Prevention and treatment of pandemic influenza in cancer patients

    Every year influenza A epidemics cause numerous deaths and millions of hospitalizations, but the most important effects are generally seen when new viral strains emerge from different species. In April 2009, for the first time in 41 years, a novel type of influenza A virus acquired the capacity for human-to-human transmission and caused a pandemic. This virus, ‘pandemic 2009 influenza A (H1N1)virus’, was derived from swine A (H1N1), which was a recombination of avian, human, and several swine influenza viruses [1]. Overall, the 2009 pandemic flu has been considered mild. In fact, most cases caused by the 2009 H1N1 virus were acute and self-limited, with the highest attack rates reported, as expected, among children and young adults. The relative sparing of adults is presumably due to the exposure of aged persons to antigenetically related influenza viruses earlier in life, resulting in the development of cross-protective antibodies [2]. The Center for Disease Control and Prevention estimates that about 59 million people were infected from April 2009 to mid- February 2010 in the United States; of these, about 265 000 were hospitalized and 12 000 died with an overall case fatality rate of 0.0203% [3]
