Research description

My research is focused on predicting and preventing death from ocular tumors.

Uveal melanoma is the most common primary intraocular tumor in adults. By the time the tumor is detected, less than five percent of patients have clinically detectable metastases. Eventually, however, almost half of patients develop metastases even if the eye has been removed. This is believed to be due to so-called micrometastases that leave the primary tumor very early. These micrometastases can remain dormant in their metastatic niche, including the bone marrow and liver, for several years. Once they leave dormancy and start growing, the patient’s prognosis is poor with a median survival of only 4–15 months. No treatment has been proven to be effective for metastatic disease, including immune checkpoint and BRAF inhibition. Uveal melanoma is thereby a cancer disease with unpredictable, high mortality and limited treatment options. I would like to help remedy this through research. To this end, I am establishing novel and accurate methods of predicting metastatic death. This knowledge will be used to develop more effective treatment strategies.

Similarly, I am trying to identify high risk groups among patients with retinoblastoma – the most common intraocular tumor in children. In an international research collaboration with Emory University, Atlanta, USA, we apply similar methods based on digital image analysis to detect genetic and chromosomal aberrations that increase the risk of metastasis.
