Transformative Pathology Fellow

Most prostate cancers detected today are slow growing, early, localized cases that have minimal risk of harming the patient. Accurate identification of very low- and low-risk patients at initial diagnosis is a major challenge due to imperfect risk-stratification tools, particularly biopsy errors and high inter-observer variability among pathologists. Despite an error rate of 40 per cent in distinguishing between low risk and intermediate risk patients, deferred treatment (active surveillance) is now the official recommendation of Canadian urologists for patients diagnosed with low grade cancers. Inability to accurately identify high grade elements on core needle biopsies makes active surveillance (AS) challenging and results in up to a third of men on AS protocols converting to radical treatment each year. Dr. Tamara Jamaspishvili’s research interest and the project goals are to identify and validate promising diagnostic and prognostic biomarkers for early prostate cancer that may be used as complementary tests by pathologists to identify subset of cancers with hidden aggressive nature.
