Hepatocellular carcinoma (HCC) is acknowledged as a cancer of unmet need, with overall survival frequently less than 7 months in patients with advanced disease. Immune checkpoint inhibitors targeting T-cell signalling pathways are producing unprecedented results in solid malignancies, including recent advances in liver cancer. However, the majority of patients derive no benefit from these drugs. We and others have reported that oncolytic viruses, therapeutic viruses that preferentially replicate in malignant cells, can be employed to prime the tumour microenvironment, rendering previously resistant tumours susceptible to immune checkpoint blockade (1,2). We have also shown that oncolytic viruses can suppress both Hepatitis B and C virus infections (3).
The trainee will investigate the use of oncolytic virus therapy to increase T-cell priming against HCC tumour specific antigens, and prime tumours for subsequent immune checkpoint blockade, thus enhancing therapy. Other areas of research include the effects of oncolytic viruses and checkpoint blockade on Natural Killer cell activity and HCV/HBV infections.
HCC research at Leeds Teaching Hospitals Trust and Leeds Institute of Cancer and Pathology (LICAP) is delivered through stakeholders including patient groups, charities, clinicians across a range of specialities and the scientific community to develop and deliver high quality translational research using new agents and technologies to improve outcomes for patients. The group has active collaborations in the UK (ICR, London, Birmingham) and elsewhere (notably the Mayo Clinic, USA and the University of Madrid, Spain). HCC research at LICAP is supported by colleagues in virology, medical oncology, surgical oncology and hepatology, with collaborative translational clinical trials spanning all the aforememntioned specialities.
The trainee will be supervised by a translational oncologist, Dr Adel Samson and a professional scientist-virologist, Dr Stephen Griffin. This mixed clinical and scientific team will provide the trainee with an excellent background in basic science research, as well as clinically relevant models of cancer immunotherapy, leading to translational clinical trials in patients with cancer.

This project is available immediately to both Home/EU rate applicants and International applicants who are able to self-fund their studies. Students must be able to provide the appropriate level of fees based on their fee status plus laboratory consumables costs per year. This is in addition to the provision of personal living expenses.
You should hold a first degree equivalent to at least a UK upper second class honours degree in a relevant subject.
Candidates whose first language is not English must provide evidence that their English language is sufficient to meet the specific demands of their study, the Faculty minimum requirements are:
- British Council IELTS - score of 6.5 overall, with no element less than 6.0
- TOEFL iBT - overall score of 92 with the listening and reading element no less than 21, writing element no less than 22 and the speaking element no less than 23.
Applicants with sufficient funding must still undergo formal interview prior to acceptance in order to demonstrate scientific aptitude and English language capability.
How to apply
Applications can be made at any time. Potential applicants are welcome to contact Adel Samson with informal enquiries about this research project.
To formally apply for this project applicants should complete a Faculty Scholarship Application form and send this alongside a full academic CV, degree transcripts (or marks so far if still studying) and degree certificates to the Faculty Graduate School.
If you have already applied for other scholarships using the Faculty Scholarship Application form you do not need to complete this form again. Instead you should email to inform us you would like to be considered for this scholarship project.
