As part of the Centre for Cancer Imaging, the Hicks laboratory uses genomic approaches and in vivo imaging of tumour biology in models of human cancer to develop new therapies and improve imaging technologies, for application in cancer patients.

Genomic studies in neuroendocrine tumour

Phaeochromocytoma and paraganglioma (PPGL) are two related tumour types that originate from the sympathetic and parasympathetic tissues of the adrenal gland or extra-adrenal paraganglia. These tumours frequently produce excess hormones that cause significant morbidity for patients and secondary life-threatening ailments. PPGL tumours are highly heritable and the disease has been linked more than 16 causative genes. We aim to identify new familial PPGL predisposition genes and understand why only some patients develop metastatic disease.

Understanding the biology of Merkel cell carcinoma

Merkel cell carcinoma (MCC) is a highly aggressive and often fatal neuroendocrine skin cancer linked to viral infection and excessive sun exposure. With a view to developing better treatments for MCC, we seek to better understand the biology of this disease, especially the viral-negative subtype. While immunotherapy has shown great promise in early clinical trials for the treatment of MCC, it is not effective for some patients. We seek to understand why only some tumours induce a strong immune response or will respond to immunotherapy, and also to investigate new approaches involving the use of radionuclide therapy or other molecular-targeted drugs.

Novel therapeutic strategies for neuroendocrine tumour

Peptide receptor radionuclide therapy is an emerging therapeutic modality for neuroendocrine tumours. Using radiolabelled peptides that selectively target a cell surface receptor typically expressed by these tumours, radionuclide therapy is highly effective in treating this heterogeneous group of cancers. We are exploring the effects of combining novel targeted therapies with radionuclide therapy, to identify novel effective therapeutic regimens to better treat this disease.
