Adjuvant anastrozole versus exemestane versus letrozole, upfront or after 2 years of tamoxifen, in endocrine-sensitive breast cancer (FATA-GIM3): a r…
2018
Background: Uncertainty exists about the optimal schedule of adjuvant treatment of breast cancer with aromatase inhibitors and, to our knowledge, no trial has directly compared the three aromatase inhibitors anastrozole, exemestane, and letrozole. We investigated the schedule and type of aromatase inhibitors to be used as adjuvant treatment for hormone receptor-positive early breast cancer. Methods: FATA-GIM3 is a multicentre, open-label, randomised, phase 3 trial of six different treatments in postmenopausal women with hormone receptor-positive early breast cancer. Eligible patients had histologically confirmed invasive hormone receptor-positive breast cancer that had been completely remov…

The Effects of Tamoxifen on Plasma Lipoprotein(a) Concentrations: Systematic Review and Meta-Analysis
2017
Introduction: Tamoxifen is a selective estrogen receptor modulator widely used in the treatment of breast cancer. Tamoxifen therapy is associated with reduced circulating low-density lipoprotein cholesterol and increased triglycerides, but its effects on other lipids are less-well studied. Aims: We aimed to investigate the effect of tamoxifen on circulating concentrations of lipoprotein(a) (Lp(a)) through systematic review and meta-analysis of available randomized controlled trials (RCTs) and observational studies. Methods: This study was registered in the PROSPERO database (CRD42016036890). Scopus, Medline and EMBASE were searched from inception until 22nd March 2016 to identify studies in…
Sorafenib: from literature to clinical practice
2013
Sorafenib is considered the standard systemic therapy for hepatocellular carcinoma (HCC), in patients with well-preserved liver function (Child-Pugh A class) and advanced-stage HCC (BCLC-C) or in patients with HCC progressing after locoregional therapies, with a high grade of recommendation. The approval of sorafenib for this indication was grounded on the efficacy and the safety results reported by two international randomized, controlled trials, the SHARP and the Asia-Pacific studies. In addition, the efficacy and the safety of sorafenib in clinical practice are addressed by several field-practice experiences, including the multinational GIDEON study and the SOFIA study. Finally, further …
G-CSF (filgrastim) treatment for amyotrophic lateral sclerosis: protocol for a phase II randomised, double-blind, placebo-controlled, parallel group,…
2020
IntroductionAmyotrophic lateral sclerosis (ALS) is a fatal progressive neurological disorder characterised by a selective degeneration of motor neurons (MNs). Stem cell transplantation is considered as a promising strategy in neurological disorders therapy and the possibility of inducing bone marrow cells (BMCs) to circulate in the peripheral blood is suggested to investigate stem cells migration in degenerated ALS nerve tissues where potentially repair MN damage. Granulocyte-colony stimulating factor (G-CSF) is a growth factor which stimulates haematopoietic progenitor cells, mobilises BMCs into injured brain and it is itself a neurotrophic factor for MN. G-CSF safety in humans has been de…
Dose-response relationship in the context of a maintenance randomized control trial: reanalysis of the PRODIGE 9 trial
2019
Introduction The dose-response relationship is considered as one of the major criteria when the causality of a relationship between an exposure and an outcome is discussed. This criterion is mainly studied in observational studies but may be also of interest in Randomized Controlled Trial (RCT), particularly if the administered dose of treatment varies over time and between patients. Maintenance trials with a long follow-up meet these characteristics. We reanalyzed a maintenance trial in digestive oncology (PRODIGE 9 trial) in order to explore the dose-response relationship between the maintenance treatment and overall survival (OS). Methods The PRODIGE 9 study was a maintenance trial asses…
A meta-analysis of single HCV-untreated arm of studies evaluating outcomes after curative treatments of HCV-related hepatocellular carcinoma
2017
Background & Aims: Determining risk for recurrence or survival after curative resection or ablation in patients with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) is important for stratifying patients according to expected outcomes in future studies of adjuvant therapy in the era of direct-acting antivirals (DAAs). The aims of this meta-analysis were to estimate the recurrence and survival probabilities of HCV-related early HCC following complete response after potentially curative treatment and to identify predictors of recurrence and survival. Methods: Studies reporting time-dependent outcomes (HCC recurrence or death) after potentially curative treatment of HCV-relat…
The impact of antiviral treatments on the course of chronic hepatitis C: an evidence-based approach.
2004
Hepatitis C virus chronic infection is currently the most common cause of end-stage liver disease. The benefit of antiviral therapy on liver histology and its impact on the long-term course of the disease has been extensively studied. However, the results are still equivocal and the overall assessment of treatment effect remains difficult to evaluate. Although the conclusions of the last National Institute of Health Consensus Development Conferences on Hepatitis C have recently been published, several important issues still remain unanswered. We review the available data by an evidence-based approach and conclude that: 1) peginterferon alfa is more effective than conventional interferon in …
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…
