Assessing the impact of COVID-19 on liver cancer management (CERO-19)
2021
[Background & Aims] The coronavirus disease 2019 (COVID-19) pandemic has posed unprecedented challenges to healthcare systems and it may have heavily impacted patients with liver cancer (LC). Herein, we evaluated whether the schedule of LC screening or procedures has been interrupted or delayed because of the COVID-19 pandemic.
Prognosis of patients with hepatocellular carcinoma treated with immunotherapy - development and validation of the CRAFITY score.
2022
Immunotherapy with atezolizumab plus bevacizumab represents the new standard of care in systemic front-line treatment of hepatocellular carcinoma (HCC). However, biomarkers that predict treatment success and survival remain an unmet need.Patients with HCC put on PD-(L)1-based immunotherapy were included in a training set (n = 190; 6 European centers) and a validation set (n = 102; 8 European centers). We investigated the prognostic value of baseline variables on overall survival using a Cox model in the training set and developed the easily applicable CRAFITY (CRP and AFP in ImmunoTherapY) score. The score was validated in the independent, external cohort, and evaluated in a cohort of patie…
Immuno-oncology in GI tumours: Clinical evidence and emerging trials of PD-1/PD-L1 antagonists.
2018
The use of immune checkpoint inhibitors constitutes an emerging therapeutic field for the therapy of gastrointestinal (GI) malignancies following the recent FDA approvals of PD-1 inhibitors for esophago-gastric adenocarcinoma, hepatocellular carcinoma and for microsatellite-instable tumors, which are mainly colorectal cancers. This paper reviews the clinical evidence end of 2017 and discusses the clinical development programs of atezolizumab, avelumab, durvalumab, nivolumab and pembrolizumab in GI-tract cancers. Since 2014, these antagonists of the PD-1/PD-L1 axis have gained approval for use in numerous other tumors. Phase II trials and phase I expansion cohorts demonstrate clinical activi…
Regorafenib with TAS-102 (REGOTAS) in metastatic colorectal cancer patients who progressed after at least two standard therapies: Efficacy and safety…
2020
158 Background: The multi-kinase inhibitor regorafenib (REGO) and oral fluoropyrimidine TAS-102 (TAS) show efficacies as single agents in treatment of refractory metastatic CRC patients (pts). We conducted a conventional 3+3 dose finding to determine a recommended phase II dose (RP2D) of its combination REGOTAS and efficacy in 3-4.-line. Methods: Eligible patients with ECOG 0-1, measurable mCRC, not amenable to surgery had at least 3rd-line treatments. Prior fluoropyrimidine-based and anti-VEGF (R) combinations were mandatory, and anti-EGFR for RAS WT tumors. TAS was given on days 1-5 and 8-12 (28-days cycle); REGO on days 2-22 (dose levels see table below). The following major AE categori…
Long-Term Efficacy of Tenofovir Monotherapy for Hepatitis B Virus-Monoinfected Patients After Failure of Nucleoside/Nucleotide Analogues
2010
Tenofovir disoproxil fumarate (TDF) has demonstrated high antiviral efficacy in treatment-naive patients with chronic hepatitis B virus (HBV) infection but experience in nucleoside/nucleotide analogue (NA)-experienced patients is limited. In this retrospective multicenter study we therefore assessed the long-term efficacy of TDF monotherapy in patients with prior failure or resistance to different NA treatments. Criteria for inclusion were HBV DNA levels >4.0 log(10) copies/mL at the start and a minimum, period of TDF therapy for at least 6 months. In all, 131 patients (mean age 42 +/- 12 years, 95 male, 65% hepatitis B e antigen [HBeAg]-positive) were eligible. Pretreatment consisted of…
Altered tactile localization and spatiotemporal integration in complex regional pain syndrome patients
2018
Background In complex regional pain syndrome (CRPS), altered perception of the affected hand and neglect-like symptoms of the affected body side are common features. In this study, we presented tactile stimuli to the affected hands in CRPS patients and matched healthy controls. Methods The participants' task was to point at the perceived positions of the stimuli using a tracking device. The spatial coordinates of the perceived positions were analysed for accuracy and consistency. We also presented patterns consisting of two stimuli at distinct positions with a delay of 100 ms. These patterns are known to induce spatiotemporal integration ("sensory saltation"). Results CRPS patients were les…
Gemcitabine plus sorafenib versus gemcitabine alone in advanced biliary tract cancer: a double-blind placebo-controlled multicentre phase II AIO stud…
2014
Background: Since sorafenib has shown activity in different tumour types and gemcitabine regimens improved the outcome for biliary tract cancer (BTC) patients, we evaluated first-line gemcitabine plus sorafenib in a double-blind phase II study. Patients and methods: 102 unresectable or metastatic BTC patients with histologically proven adenocarcinoma of gallbladder or intrahepatic bile ducts, Eastern Cooperative Oncology Group (ECOG) 0–2 were randomised to gemcitabine (1000 mg/m2 once weekly, first 7-weeks + 1-week rest followed by once 3-weeks + 1-week rest) plus sorafenib (400 mg twice daily) or placebo. Treatment continued until progression or unacceptable toxicity. Tumour samples were p…
Perioperative chemotherapy with fluorouracil plus leucovorin, oxaliplatin, and docetaxel versus fluorouracil or capecitabine plus cisplatin and epiru…
2019
Background Docetaxel-based chemotherapy is effective in metastatic gastric and gastro-oesophageal junction adenocarcinoma. This study reports on the safety and efficacy of the docetaxel-based triplet FLOT (fluorouracil plus leucovorin, oxaliplatin and docetaxel) as a perioperative therapy for patients with locally advanced, resectable tumours. Methods In this controlled, open-label, phase 2/3 trial, we randomly assigned 716 patients with histologically-confirmed advanced clinical stage cT2 or higher or nodal positive stage (cN+), or both, resectable tumours, with no evidence of distant metastases, via central interactive web-based-response system, to receive either three pre-operative and t…
