Uveal melanoma (UM for short) is a rare form of ocular or eye cancer that will spread or metastasise to the liver in half of all patients. Although it is a rare disease, Ireland has one of the highest incidence rates of this cancer in the world. Once UM spreads to the liver, patients are faced with an extremely poor prognosis as there are currently no treatments that stop UM spreading from the eye to the liver. This means that as few as 8% of patients diagnosed with metastatic UM will survive beyond 2 years.
In this project, we will establish a pipeline to access precious tumour biopsies and blood samples from patients being monitored for, or diagnosed with, metastatic UM across Ireland. This will allow us to work closely with our colleagues in hospitals across Ireland to better understand and treat this disease. Studying patient samples gives us the best opportunity of discovering how exactly this cancer grows and spreads within the body. We will analyse blood samples to identify markers in the blood that will tell us how likely the cancer is to spread outside of the eye, and whether a patient may respond to treatment. Our lab has identified drugs that stop the growth of UM cells in a dish. Throughout this project, we will collect tumour biopsies from patients diagnosed with metastatic UM and treat them with these drugs to see if they have the same effect on patient tumours.

Clinical Challenge being addressed: Metastatic uveal melanoma is an extremely poor prognosis cancer and unfortunately, Ireland has one of the highest incidence rates of this cancer in the world. Identifying new therapeutic targets in this disease are critical to improving patient prognoses. Very few patients  present  with  detectable  metastases  upon  primary  treatment,  yet  half  of UM patients  will ultimately develop  metastatic  disease. Through analysing differentially expressed transcripts and proteins in patient blood samples, we may be able to develop a method of detecting dissemination faster than currently used imaging techniques.

In addition, this project will seed sustainable growth of a collaborative Uveal Melanoma Research Group in Ireland. During  this  research  we  move  towards  personalised  treatments  for  UM  patients,  identifying  which patient  cohorts  respond  best  to  new  drug  therapies  and  currently  available  chemotherapeutics.  This will  impact  patients  in  the  future  by  identifying  which  patients  are  likely  to  respond  best  to  specific treatments.
