• Biomarkers for chemotherapy resistance in breast cancer

Research Summary:

The focus of Dr. Tran’s research is to identify predictive (i.e. pre-treatment) and early-response biomarkers for tumour response to chemotherapy and radiotherapy. Specifically, Dr. Tran is interested in exploring quantitative imaging biomarkers from computed tomography imaging, digital pathology, and optical imaging alongside specimen-based markers to design computer-aided theragnostic (CAT) systems. The primary endpoint of Dr. Tran’s research will be improved patient outcomes by using biomarker measurements for adaptive and response-guided cancer treatments.

Within this framework, Dr. Tran’s research is also focused on understanding treatment and survival outcomes associated with biological variances in early-stage invasive breast cancer. As part of a team of physician investigators and scientists, he is working alongside clinical experts to map the genetic and biological characteristics associated with chemotherapy resistance and radiation refractory breast cancer.
