Biology and significance of alpha‐fetoprotein in hepatocellular carcinoma
2019
Hepatocellular carcinoma (HCC) is one of the most common causes of cancer-related deaths globally due, in part, to the majority of patients being diagnosed with intermediate or advanced stage disease. Our increased understanding of the heterogeneous molecular pathogenesis of HCC has led to significant developments in novel targeted therapies. Despite these advances, there remains a high unmet need for new treatment options. HCC is a complex disease with multiple pathogenic mechanisms caused by a variety of risk factors, making it difficult to characterize with a single biomarker. In fact, numerous biomarkers have been studied in HCC, but alpha-fetoprotein (AFP) remains the most widely used …
NAFLD-driven HCC: Safety and efficacy of current and emerging treatment options
2022
In light of a global rise in obesity and type 2 diabetes, non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) represent an increasingly important underlying aetiology of hepatocellular carcinoma (HCC). HCCs arising from lipotoxicity-mediated chronic inflammation are characterised by several unique features: in contrast to virally driven HCC, up to 50% of NAFLD-HCC occurs in patients without cirrhosis and annual HCC incidence is comparatively low, complicating current surveillance strategies. On average, patients are older and are more frequently diagnosed at an advanced stage. While locoregional treatments are probably equally effective regardless of HCC aetio…
Direct-acting antiviral agents and risk of Hepatocellular carcinoma: Critical appraisal of the evidence
2021
Direct-acting antivirals (DAAs) revolutionized the treatment of chronic HCV-related disease achieving high rates of sustained virological response (SVR), even in advanced cirrhosis, with modest contraindications and a low rate of adverse events. However, the risk of hepatocellular carcinoma (HCC) persists due to the underlying chronic liver disease, both in patients with and without history of HCC. Although some initial studies reported a presumptive high risk of HCC development after DAA therapy, more recent observational studies denied this hypothesis. The residual risk for HCC occurrence after HCV eradication seems being progressively reduced with time after SVR. Data on recurrence of HC…
Does chemotherapy prevent HCV-related hepatocellular carcinoma? Cons.
2010
The accuracy and the reliability of well-recognized clinical, virologic, histologic, and molecular risk factors for hepatocellular carcinoma (HCC) are still insufficient. Thus, accurate risk prediction of cancer development in individual patients with the aim of selecting high risk cohorts of patients for HCC chemoprevention programs remains an elusive goal. Future directions in chemoprevention of HCC will be in the development of molecular risk models and of new chemopreventive agents. Studies examining multiple genes and proteins (genomics and proteomics) in the same HCCs will be required to evaluate this possibility thoroughly. A strategy aiming at preventing chronic liver disease of any…
Gene signatures in CRC and liver metastasis
2011
Colorectal cancer (CRC) is one of the most common causes of cancer-related death with a worldwide incidence of almost a million cases annually in both males and females. The accelerated decrease in CRC incidence rates from 1998 to 2006 largely reflects the advances in diagnosis and treatment that have enabled to detect and remove precancerous polyps. However, the screening technology has not resulted in major improvements in the prognosis of patients with advanced cancer and the liver metastasis remains the major cause of death in CRC. About 25% of patients have detectable liver metastasis at diagnosis, that are classified as “synchronous” lesions and approximately 70% of patients develop a…
Programmed colorectal cancer screening decreases incidence and mortality
2019
Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the second leading cause of cancer- related deaths in the world (1). Detecting and removing precancerous lesions or detecting tumors in early stages through endoscopy decreases CRC mortality (2). Randomized controlled trials (RCTs) have shown that CRC screening based on guaiac fecal occult blood testing (gFOBT) and flexible sigmoidoscopy is effective in reducing incidence and mortality rates of CRC (3).
Cetuximab: clinical results in colorectal cancer
2007
In recent years, the introduction of targeted therapies into clinical practice seems to offer incremental benefits in the treatment of metastatic colorectal cancer (mCRC), mainly when they are employed in combination with optimal chemotherapy and/or radiotherapy. In this paper, we focus on Cetuximab and its role in the treatment of mCRC.
Treatment of pancreatic cancer: A narrative review of cost-effectiveness studies.
2013
Cancer of the pancreas is the second most frequent digestive cancer in the US, accounting for about 44,000 new cases per year. In Europe, it is the sixth most frequent cancer, accounting for 2.8% of cancers in men and 3.2% in women. With a five-year survival of less than 10%, it is the fifth leading cause of cancer-related death. The majority of cases are diagnosed above the age of 65 and in about 60% of cases at an advanced stage, explaining that little improvement has been observed in survival over the past 30 years. Radical surgery offers the only curative treatment of pancreatic cancer. Alternative or combined therapeutic options in particular consist of adjuvant or neoadjuvant chemothe…
How to find the Ariadne's thread in the labyrinth of salvage treatment options for metastatic colorectal cancer?
2014
Abstract: Since a chance for cure was found out in metastatic colorectal cancer (mCRC) patients undergoing a resection of liver and lung metastases, high tumor shrinkage by chemotherapy regimens and their combination with targeted agents have been addressed in potentially resectable mCRC. However, most mCRC patients cannot reach this opportunity because of tumor burden or metastatic sites. For these patients a salvage systemic therapy could be offered to prolong survival. To date, a huge number of clinical trials provided some evidences for the achievement of this goal. A lot of chemotherapeutic regimens in combination with biological therapies are now available. We tried to propose a simpl…
Does neoadjuvant FOLFOX chemotherapy improve the prognosis of high‐risk Stage II and III colon cancers? Three years' follow‐up results of the PRODIGE…
2021
International audience; Aim Neoadjuvant chemotherapy has proven valuable in locally advanced resectable colon cancer (CC) but its effect on oncological outcomes is uncertain. The aim of the present paper was to report 3-year oncological outcomes, representing the secondary endpoints of the PRODIGE 22 trial. Method PRODIGE 22 was a randomized multicentre phase II trial in high-risk T3, T4 and/or N2 CC patients on CT scan. Patients were randomized between 6 months of adjuvant FOLFOX (upfront surgery) or perioperative FOLFOX (four cycles before surgery and eight cycles after; FOLFOX perioperative). In wild-type RAS patients, a third arm testing perioperative FOLFOX-cetuximab was added. The pri…
