Efficacy and safety of irinotecan-based chemotherapy for advanced colorectal cancer outside clinical trials: an observational study.

2010

Background: This prospective observational study in typical community-based outpatient clinics evaluated the efficacy and toxicity of weekly and biweekly irinotecan-based chemotherapies and their compatibility depending on age. Methods: 601 patients with advanced or metastatic colorectal cancer receiving first-, second-, or third-line irinotecanbased therapy were regularly analyzed for response and toxicity until the end of therapy. Results: The median age was 65 (28–87) years, approximately one-third of the patients were ≥70 years old. Of all patients, 405 were treated weekly and 68 biweekly. Median overall survival (OS) for first-line therapy was 26.5 months for the <70-year-old patients …

An a priori prediction model of response to peginterferon plus ribavirin dual therapy in naïve patients with genotype 1 chronic hepatitis C.

2014

none 29 no Background: Aim was to select naïve patients with genotype 1 chronic hepatitis C having a high probability of response to Peg-interferon. +. ribavirin therapy. Methods: In 1073 patients (derivation cohort), predictors of rapid and sustained virological response were identified by logistic analysis; regression coefficients were used to generate prediction models for sustained virological response. Probabilities at baseline and treatment week 4 were utilized to develop a decision rule to select patients with high likelihood of response. The model was then validated in 423 patients (validation cohort). Results: In the derivation cohort, 257 achieved rapid virological response and 8…

Safety of the first dose of fingolimod for multiple sclerosis: results of an open-label clinical trial

2014

BACKGROUND: In patients with relapsing-remitting MS (RRMS) fingolimod prevents disease relapses and delays disability progression. First dose administration of fingolimod is associated with a transient, dose-dependent decrease in heart rate (HR) in the 6 hours after drug intake.The aim of the study is to to assess safety and tolerability of the first dose of fingolimod in a cohort of Italian patients with RRMS without alternative therapeutic options. METHODS: Open-label, single arm, multicentre study. After the first dose of fingolimod, patients were observed for 6 hours and had their vital signs monitored hourly. Extended on-site monitoring was provided when required. RESULTS: Of the 906 p…

Cancer Stem Cells Sensitivity Assay (STELLA) in Patients with Advanced Lung and Colorectal Cancer: A Feasibility Study.

2015

Background Cancer stem cells represent a population of immature tumor cells found in most solid tumors. Their peculiar features make them ideal models for studying drug resistance and sensitivity. In this study, we investigated whether cancer stem cells isolation and in vitro sensitivity assay are feasible in a clinical setting. Methods Cancer stem cells were isolated from effusions or fresh cancer tissue of 23 patients who progressed after standard therapy failure. Specific culture conditions selected for immature tumor cells that express markers of stemness. These cells were exposed in vitro to chemotherapeutic and targeted agents. Results Cancer stem cells were extracted from liver metas…

A Systematic Review of the Emerging Role of Immune Checkpoint Inhibitors in Metastatic Castration-resistant Prostate Cancer: Will Combination Strateg…

2020

Abstract Context The role of immune checkpoint inhibition (ICI) in the treatment of prostate cancer (PC) still remains elusive. It has been proposed that combination of ICI with other molecules increases the efficacy of immunotherapy in PC. Objective To systematically review the literature to assess the potential role of ICI in combination with additional therapies for the management of metastatic castration-resistant PC (mCRPC). Evidence acquisition A systematic review using Medline and scientific meeting records was carried out in September 2020 according to the Preferred Reporting Items for Systematic Review and Meta-analyses guidelines. Ongoing trials of immunotherapy with standard mCRP…

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 …

Nitric Oxide and Platinum-Derivative-Based Regimens for Cancer Treatment: From Preclinical Studies to Clinical Trials

2017

Abstract Chemoresistance to platinum-based antitumor agents remains a major hindrance faced by patients with a wide variety of solid tumors. New effective strategies are still needed to improve chemosensitization and overcome chemoresistance of tumors by platinum-based chemotherapies. Over the past decade, considerable knowledge on the antitumor effect of nitric oxide (NO) and its mechanisms of action has been gained. Here, we provide an overview of the basic mechanisms of resistance to platinum-based drugs and how NO can bypass this chemotherapy resistance. Preclinical and clinical studies focused on combination therapy using platinum chemotherapeutic drugs with NO donors have demonstrated…

The role of AXL as mechanism of resistance to trastuzumab and a prognostic factor in breast cancer HER2 positive: A translational approach

2019

Abstract Background Breast cancer (BC) is a heterogeneous disease. HER2+ BC represents between 15-30% of cases. Trastuzumab (T), a monoclonal antibody, has been successfully improved clinical benefits in both adjuvant and in metastatic settings. Despite this evidence, many patients experience resistance to therapy. The objective of this study is to assess AXL as a potential mechanism of resistance and its implication as a prognostic factor. Methods We used three cell lines with acquired resistance to T. Resistant models were generated by treating parental cells (AU565, SKR3, BT474) with constant dose of T (15mg/mL) for 6 months. Cell viability was estimated by MTT assay. Proteins were asses…
