Overview

Dr. Gowdy is actively involved with national and international bodies working to harmonize the staging and response criteria for childhood cancers, in particular, Hodgkin lymphoma using functional imaging techniques such as PET/CT.

Research

SEARCH for CAYAHL
As part of this International collaborative group, Dr. Gowdy is leading a systematic review into the role of metabolic PET parameters to act as a biomarker of disease for children and young adults with Hodgkin lymphoma to aid upfront risk stratification and direct clinicians to those high-risk individuals who may benefit from intensification of therapy.

PETool
Train and validate an automated segmentation technique using an AI tool developed at UBC to delineate disease in children and young adults with lymphoma. Use the segmentations to calculate metabolic PET parameters and radiomic features as we work to identify biomarkers of disease which can stage and evaluate response of disease to therapy.
