Basal cell carcinoma • cutaneous T-cell lymphoma • gene expression profiling • oncolytic viruses • cancer epidemiology
My laboratory studies the genetic bases of cutaneous T-cell lymphoma (CTCL) carcinogenesis and cancer progression with a focus on application and translation of the newly discovered molecular knowledge into clinical practice. We are elucidating how hypopigmented mycosis fungoides (MF), which primarily affects adolescents and young adults, differs from classic patch/plaque MF, which affects older individuals. We are actively developing a novel diagnostic/prognostic molecular test for CTCL patients, which would help distinguish this disease from its benign mimickers and help identify certain patients (approximately 20%) who are at risk of disease progression. We are also studying the expression and function of cancer testis (CT) and embryonic stem cell (ESC) genes in CTCL. In addition, working with our collaborators, we are investigating novel treatment approaches using oncolytic viruses for CTCL, basal cell and squamous cell carcinomas. Another branch of research in the lab is to study the geographic distribution of human cancers in Canada.
