Our work
Our mission at the Pereira/Acedo Group (@PereiraAcedoLab) 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

Clinical activities
A. Clinical trials
Our trials are based on testing Novel Therapies such as endoscopic ultrasound-guided radiofrequency ablation or irreversible electroporation (IRE).
UroPanc - Early detection of pancreatic ductal adenocarcinoma (PDAC) using a panel of biomarkers (ClinicalTrials.gov # NCT04449406).
The £1.6m PCRF funded study is designed to further validate a previously identified urinary biomarkers and the algorithm for their analysis, PancRISK. We aim to establish the sensitivity and specificity of the biomarkers and how accurately will PancRISK stratify patients for further clinical work up. We will also establish if the urine test will enable early detection of PDAC, and finally, what would be the potential economic and social impact of using this test (collaboration with Imperial College, London). Samples are being collected at several sites including UCLH, Royal London Hospital, the University of Liverpool (EUROPAC) and San Raffaele Hospital (Milan).
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 vital to ensure that those that are due to cancer are diagnosed early. We hope the results of this study will help develop new tests to diagnose pancreatic cancer and NETs of the pancreas at an early stage.
