Hepatocellular cancer: optimal strategies for screening and surveillance.

2009

Hepatocellular carcinoma (HCC) is a challenging malignancy of global importance and is associated with a high rate of mortality. Individuals with chronic viral hepatitis and other forms of liver disease are at risk for developing HCC. The stage of cancer dictates the therapeutic choice, making early detection a primary objective. Many observational studies have reported that HCC is diagnosed at an earlier stage in patients who received surveillance. The guidelines of the American Association for the Study of Liver Diseases suggest that surveillance should be performed using ultrasonography at an interval of every 6–12 months. This interval is based upon mainly observational data and the exp…

Predicting survival in patients with hepatocellular carcinoma treated by transarterial chemoembolisation

2011

Aliment Pharmacol Ther 2011; 34: 196–204 Summary Background  Transarterial chemoembolisation (TACE) is first-line treatment in unresectable hepatocellular carcinoma (HCC) and rescue treatment after failure of radical treatments in early stage HCC. Prognostic tools for HCC using time-fixed Cox models may be unreliable in patients treated with TACE because time-varying predictors interact. Aim  To explore time-dependent variables as survival predictors in patients with HCC receiving TACE as first-line or second-line treatment. Methods  Eighty four consecutive patients with HCC (mean age 68; male gender 62%; Child-Pugh class: A n = 73, B n = 11; Barcelona Clinic Liver Cancer class: A n = 44, B…

The multidisciplinary management of gastro-oesophageal junction tumours

2016

Abstract Background and scope The management of GOJ cancers remains controversial and may vary between countries. Evidence-based attitudes and guidelines are not easy to elaborate since most of the trials and studies reported mixed cases of oesophageal (both adenocarcinoma and squamous cell tumours), GOJ and gastric cancers. The aim of this expert discussion and position paper is to elaborate practical recommendations that integrate evidence-reported literature and experience-based attitude covering all clinical aspects of GOJ cancer across different specialities and countries in Europe. Methodology Opinion leaders, selected on scientific merit were asked to answer to a prepared set of ques…

Biliary microbiota in pancreatic cancer

2019

The most common microorganisms were Pseudomonas spp. (P < 0.0001) and E. coli (P < 0.0001), which were negatively correlated to PDAC and positively correlated to cholangiocarcinoma by both univariate and multivariate analysis. Gram-negative bacteria are linked to a tumor-associated inflammatory status

Adjuvant Chemoradiation Therapy in Gastric Cancer: Critically Reviewing the Past and Visualizing the Next Step Forward

2015

Gastric cancer remains one of the most common malignancies worldwide. Despite the significant advances in surgical treatment and multimodality strategies, prognosis has modestly improved over the last two decades. Locoregional relapse remains one of the main issues and the combined chemoradiation treatment seems to be one of the preferred approaches. However, more than ten years after the hallmark INT-0116 trial, minimal progress has been made both in terms of effectiveness and toxicity. Moreover, new regimens added to combined therapy failed to prove favourable results. Herein, we attempt a thorough literature review comparing pros and cons of all relative studies and potential bias, targe…

Is chromoendoscopy the new standard for cancer surveillance in patients with ulcerative colitis?

2008

Chromoendoscopy was introduced in 2003 as a novel 'red flag' technique that aimed to increase the sensitivity of identifying flat, neoplastic lesions in patients with ulcerative colitis. The improved sensitivity of chromoendoscopy over standard white-light endoscopy has been confirmed in European and Asian centers. This commentary discusses the findings from a prospective, controlled study from the Mount Sinai Hospital in New York. The findings of this study provide unequivocal evidence that chromoendoscopy is superior to white-light endoscopy in the detection of neoplasias in patients with IBD. The authors of this study identified a greater number of lesions and a higher number of patients…

Endoscopic Resection for High-Grade Dysplasia in Barrett’s Esophagus

2005

Endoscopic resection (ER) has gained more and more importance in the treatment of high grade dysplasia (HGD) in Barrett's esophagus over the last few years. The choice of the different available techniques depends on the macroscopic type of the lesion and the personal experience of the endoscopist. But the "suck and cut"-technique with ligation device or cap should be favoured to normal strip biopsy in the esophagus because of the size of the resected specimen and its technical feasibility. Several studies demonstrate the effectivity and safety of ER in patients with HGD, therefore ER should be the treatment of choice in these patients.

Systematic review of the diagnosis of gastric premalignant conditions and neoplasia with high-resolution endoscopic technologies

2013

Aim. The aim of the article is to systematically review the current evidence on the diagnostic use of narrow band imaging (NBI), flexible spectral imaging color enhancement (FICE) and endoscopic image enhancement technology i-scan endoscopies for gastric precancerous and cancerous lesions. Materials and methods. Original manuscripts were searched in PubMed until October 2012. Pertinent data were collected and pooled diagnostic accuracy measures were estimated when possible. Results. In total, 38 studies were evaluated. Thirty-one studies were included for NBI and 7 studies for FICE assessment in this systematic review. No article was found meeting inclusion criteria for i-scan endoscopy. Th…
