Prognostic significance of circulating PD-1, PD-L1, pan-BTN3As and BTN3A1 in patients with metastatic gastrointestinal stromal tumours (mGISTs)

2019

Abstract Background Gastrointestinal stromal tumours (GISTs) account for 1% of all primary gastrointestinal cancers. In cancer, suppressive immune checkpoints, including butyrophilin sub-family 3A/CD277 receptors (BTN3A), programmed death protein (PD-1) and its ligand PD-L1, are often hyper-activated to ensure an effective evasion of tumor cells from immune surveillance. Since recent studies showed that PD-1 and PD-L1 expression in cancer may be an important prognostic factor, the aim of our study was to investigate if soluble forms of inhibitory immune checkpoints can help predict survival in metastatic GIST patients. Methods Using specific homemade ELISA assays not yet commercially availa…

Immunotherapy: New Options in Gastrointestinal Cancers?

2019

Novel ways to sensitise gastrointestinal cancer to apoptosis.

2009

Gastrointestinal (GI) cancers are major health problems, being the most common cancers worldwide. Resistance to apoptosis is closely linked to carcinogenesis and enables malignant cells to evade therapy-induced cell death. In the recent past, the increasing understanding of molecular pathways of apoptosis has provided novel targets in cancer therapy. Several drugs, either inhibiting antiapoptotic signalling or actively inducing apoptosis in cancer cells, have already entered clinical trials. Until now, agents targeting apoptosis pathways are primarily being tested alone or in combination with chemotherapy. In the near future, personalized combination therapies will probably be beneficial fo…

The Interplay of Religious and Nonreligious Meaning-Making on Psychological Well-Being in Gastrointestinal Cancer Patients

2020

Previous research has identified close relationships between religious and nonreligious factors and well-being in cancer patients. This study expands on such studies by examining the interplay of r...

Chemokine receptor CXCR4-prognostic factor for gastrointestinal tumors

2008

To review the implication of CXCR4 for gastrointestinal cancer, a "Pubmed" analysis was performed in order to evaluate the relevance of CXCR4 and its ligands for gastrointestinal cancers. Search terms applied were "cancer, malignoma, esophageal, gastric, colon, colorectal, hepatic, pancreatic, CXCR4, SDF-1alpha, and SDF-1beta". CXCR4 expression correlated with dissemination of diverse gastrointestinal malignomas. The CXCR4 ligand SDF-1alpha might act as "chemorepellent" while SDF-1beta might act as "chemorepellent" for CTLs, inducing tumor rejection. The paracrine expression of SDF-1alpha was furthermore closely associated with neoangiogenesis. CXCR4 and its ligands influence the disseminat…

Overview on SNIFFPHONE:A portable device for disease diagnosis

2019

We present SNIFFPHONE, a handy and easy-To-use device that allows the non-invasive detection of gastric diseases. It analyzes the user's exhaled breath using specifically developed gas sensors. The device is coupled to a smartphone, which governs the breath analysis process, sends the data measurements to an external data analysis server, and finally gives feedback to the user. In this work, we describe the SNIFFPHONE device and the general platform under development.

Olive oil intake and cancer risk: A systematic review and meta-analysis

2022

Background Research evidence has established the beneficial effects of diet in cancer prevention; various epidemiological studies have suggested that olive oil component could play a role in decreasing cancer risk. This systematic review and meta-analysis aims to investigate the association between olive oil consumption, cancer risk and prognosis. Methods A systematic search was conducted in PubMed, EMBASE and Google Scholar databases (end-of-search: May 10, 2020). Pooled relative risk (RR) and 95% confidence intervals (95% CIs) were estimated with random-effects (DerSimonian-Laird) models. Subgroup analyses, sensitivity analyses and meta-regression analysis were also performed. Results 45…

Molecular imaging of VEGF in gastrointestinal cancer in vivo using confocal laser endomicroscopy

2010

Vascular endothelial growth factor (VEGF) is a therapeutic target in gastrointestinal cancer (GiC). However, its in vivo visualisation could not be achieved to date with endoscopic techniques. Confocal laser endomicroscopy (CLE) is a novel imaging technique for gastrointestinal endoscopy providing in vivo microscopy at subcellular resolution. The aim of the study was to evaluate CLE for in vivo molecular imaging of VEGF in GiC.Molecular imaging of tumours in APCmin mice, in xenograft models and in surgical specimens of patients with colorectal cancer (CRC) was achieved after application of labelled antibodies. The tumour sites were scanned with the probe for the strongest specific fluoresce…
