The Childhood Liver Oncology Group (c-LOG), is a pioneer research group dedicated to improve the survival and quality of life of children with liver cancer. Their primary focus is hepatoblastoma, a rare but aggressive cancer affecting young children. c-LOG aims to understand the causes of this disease and develop better treatments and risk stratification algorithms to reduce chemotherapy associated side effects, ultimately improving the lives of these patients. The interest of the group is also to translate the results in childhood liver cancer to the main primary liver cancer in adults, the hepatocellular carcinoma (HCC).

To achieve this goal, c-LOG established a comprehensive biorepository of biological samples from pediatric patients with liver cancer called CLCN (Childhood Liver Cancer Network Collection) thanks to the participation in the Pediatric Hepatic International Tumor Trial (PHITT). Besides, c-LOG collaborates with the Gastroenterology department of the Germans Trias i Pujol University Hospital to collect biological specimens from adult patients with liver diseases for a more comprehensive understanding of liver cancer in general.

    Carolina Armengol Niell, PhD

    Carolina Armengol has over 20 years of experience in studying childhood liver cancer. She is the head of the Childhood Liver Oncology Group (c-LOG), which she founded in 2010 at Germans Trias i Pujol Research Institute (IGTP), affiliated with the CIBERehd group of which she is also the leader. c-LOG is a pioneer in translational research on childhood liver cancer in Spain and is recogniSed as a reference group internationally. Her research has always focused on directly studying patient samples to better understand the disease and apply the results into clinical practice.

Research lines

Consolidation of a unique European biorepository of childhood liver cancer

To establish a network to collect biological samples of paediatric patients with liver cancer with the suport of their families, paediatric oncologists, surgeons and pathologists.

Identification and validation of diagnostic and prognostic biomarkers to improve quality of life and survival of patients with liver cancer

To validate assessing biomarkers in diagnostic samples from a prospective cohort of European patients enrolled in the first Paediatric Hepatic International Tumour Trial (PHITT) in order to improve the current clinical stratification and clinical management of childhood liver cancer.

To assess the same biomarkers in adult cancer and study its diagnostic and prognostic potential.

Understanding the molecular biology of childhood liver cancer

To improve the knowledge of rare and highly aggressive forms of childhood liver cancer that are resistant to current therapies and to identify biomarkers and therapeutic targets to design more effective therapies using the latest high-throughput technologies and advanced computational tools.

Moving forward precission medicine in childhood liver cancer through the identification of the best drugs for each tumour type ​​​​​​

To test innovative therapies against different tumour subtypes using patient-derived models of childhood liver cancer such as patient-derived xenografts and patient-derived organoids.
