Liver and Pancreaticobiliary Cancer

Our work 

Our mission at the Pereira/Acedo Group is to lead the way in advancing the understanding and management of liver, pancreatic, and biliary diseases.  

With a strong emphasis on clinical excellence and translational research, we are dedicated to unravelling the complexities of these challenging conditions, seeking minimally invasive early detection biomarkers, and developing novel therapeutic strategies to improve patient outcomes. 

As a major education site, we are committed to nurturing the next generation of medical professionals, providing comprehensive training. 

Collaborating with esteemed institutions globally, we aim to create a dynamic, multicultural research hub that fosters innovative solutions and translates scientific discoveries into tangible improvements in patient care. 

Translational research 

This research focuses on the discovery and validation of early detection biomarkers and the evaluation of novel therapeutic strategies to improve the outcome of patients with pancreaticobiliary diseases (e.g. cholangiocarcinoma and pancreatic cancer). 

Our work includes: 

• Biomarker discovery and validation for early diagnosis  
• Biomarkers as surrogate markers for treatment response  
• Serum, tissue and urine biobank collection  
• Nanoparticles as diagnostic tools and drug delivery systems 
• 3D disease models (e.g. scaffolds, organoids)  
• Light-based and minimally-invasive therapies 
• Imaging studies 
• Spatial Transcriptomics 

UCL Spatial Biology Hub (SBH) at ILDH

We provide services for studies involving the use of spatial biology (currently Nanostring GeoMx and CosMx technologies). Get in touch if you are interested. Supporting staff:

• Dr Pilar Acedo: SBH Academic Lead
• Reuben Asher: SBH Research Technician 
• Daniel Parra: Research Assistant at Pereira/Acedo Lab

Clinical activities

A. Clinical trials 

Our clinical trials are based on testing Novel Therapies such as endoscopic ultrasound-guided radiofrequency ablation or irreversible electroporation (IRE). 

B. Clinical Studies

ADEPTS - Accelerated Diagnosis in neuroEndocrine and Pancreatic TumourS

In this study, doctors and researchers want to look at blood, urine and tissue samples from people who have symptoms similar to those with:

• Pancreatic cancer
• Neuroendocrine tumours (NETs) of the pancreas
• Bile duct cancer 

In most cases, such symptoms are caused by many other benign conditions. But it is important to make sure that those that are due to cancer are diagnosed early. We hope the results of this study will help them develop new tests to diagnose pancreatic cancer and NETs of the pancreas at an early stage.
