About

The Childhood Liver Oncology Group (c-LOG), is a pioneering translational research team dedicated to improving survival rates and quality of life for children diagnosed with liver cancer, with a primary focus on hepatoblastoma but also in hepatocellular carcinoma in children, both rare cancers. While liver cancer in children generally has a good prognosis, survival is poor for patients with aggressive and chemo resistant tumours. Furthermore, survivors often suffer lifelong secondary effects due to high doses of chemotherapy. Due to the rarity of these diseases (approximately one case per million), they have made significant efforts to collect samples from affected infants and children as the foundation of its research. The team addresses the challenge of understanding the underlying causes of these diseases to develop improved treatment strategies and risk stratification algorithms aimed at increasing patient survival and minimizing chemotherapy-related side effects.

To accomplish these objectives, they established the Childhood Liver Cancer Network Collection (CLCN), a comprehensive European biorepository of biological samples from paediatric liver cancer patients. This resource was developed in collaboration with the Paediatric Hepatic International Tumour Trial (PHITT) and through partnerships with hospitals across Europe. Additionally, they collaborate with the Gastroenterology Department at Germans Trias i Pujol University Hospital to collect biological specimens from adult patients with liver diseases, facilitating a broader understanding of liver cancer, including its adult form, hepatocellular carcinoma.

Research efforts focus on several key areas:

  • Consolidating a unique European biorepository that serves as a vital resource for current and future translational research.
  • Investigating the molecular biology of childhood liver cancer to identify biomarkers and therapeutic targets, particularly for tumours resistant to current therapies.
  • Discovering and validating diagnostic and prognostic biomarkers to enhance clinical risk stratification and improve patient management within the context of the PHITT trial, with the aim of applying these findings in future clinical trials.
  • Advancing precision medicine by employing patient-derived models, such as xenografts and organoids, to test innovative, individualized therapies tailored to specific tumour subtypes.

The group faces challenges common to rare paediatric cancers, including limited patient numbers and the complexity of translating molecular findings into effective treatments. Nevertheless, their integrative approach -combining clinical collaboration, advanced technologies, and international cooperation- positions it to make significant contributions toward more effective, less toxic therapies, ultimately improving outcomes for children with liver cancer.

    Carolina Armengol Niell

    Carolina Armengol Niell has over 28 years of experience in translational liver cancer research, focusing on both paediatric and adult patients. She holds degrees in Biology (1996) and Biochemistry (1998), a PhD in Biochemistry conducted at the Hospital Clínic and Faculty of Medicine of the University of Barcelona (2004), and completed a postdoctoral fellowship at the Institut Pasteur in Paris (2004-2007). Supported by a Ramón y Cajal contract (Ministry of Economic Affairs and Digital Transformation), she founded the Childhood Liver Oncology Group (c-LOG) at IGTP in 2010, which is affiliated with CIBERehd as part of the CB06/04/0033 group, where she also serves as the leader.

    Dr Armengol has been a pioneer in translational research on childhood liver cancer in Spain, and her research group is internationally recognised as a reference group in the field. She currently serves as chair of the biology and pathology committee for the International Childhood Liver Tumour Strategy Group (SIOPEL). Her research focuses on directly studying patient samples to better understand the disease and translate findings into clinical practice, with the ultimate goal of improving patients' quality of life.

    Dr Armengol's work is supported by competitive funding from national and international agencies. She currently leads two coordinated projects at the national and EU levels. She has published extensively in high-impact journals and actively collaborates with industry partners to develop diagnostic devices and novel therapeutic approaches for aggressive liver tumours.

Research lines

Establishing a unique European biorepository for childhood liver cancer

They are building a robust network of collaborations with hospitals across Europe to collect biological samples from paediatric patients with liver cancer. This initiative is made possible through the invaluable support of families, paediatric oncologists, surgeons, and pathologists, creating a unique resource for advancing research and treatment. 

Unravelling the molecular biology of childhood liver cancer

Their research focuses on deepening the understanding of rare and highly aggressive forms of childhood liver cancer, particularly those resistant to current therapies. Using cutting-edge high-throughput technologies and advanced computational approaches, the group aims to identify critical biomarkers and therapeutic targets to enable the development of more effective treatments.

Diagnostic and prognostic biomarker discovery to enhance patient outcomes

They are committed to identifying and validating diagnostic and prognostic biomarkers using samples from European patients enrolled in the pioneering Paediatric Hepatic International Tumour Trial (PHITT). These efforts are designed to refine clinical risk stratification and improve the management and quality of life of children with liver cancer.

Advancing precision medicine in childhood liver cancer​​​​​​

The group is at the forefront of testing innovative therapies tailored to individual patients. By leveraging advanced patient-derived models, such as xenografts and organoids, they aim to identify therapeutic targets and the most effective drugs for each tumour subtype, paving the way for precision medicine in paediatric liver cancer.
