Ultrasound Spectroscopy as Early Indicators of Radiation Treatment Response in Prostate, Rectum and Head & Neck Cancers
Sponsor: Sunnybrook Health Sciences Centre
Summary
Our objective in this study is to identify an optimal ultrasound spectroscopy parameter that can be used as an early predictor of pathological complete or partial response in men with prostate cancer and men and women with rectum and head and neck cancers receiving treatment radiotherapy. We have previously demonstrated that high-frequency ultrasound and spectroscopy, and recently conventional-frequency ultrasound and spectroscopy may be used to detect cell death in vitro, in situ and in vivo. The method can detect different forms of cell death and has been demonstrated to be sensitive to apoptotic, necrotic and mitotic cell death. The main goal, as described above, is to select the best ultrasound spectroscopy parameter to use as an early predictor of pathological complete response

Interventions
Ultrasound Imaging
Ultrasound Spectroscopy assess changes in five different ultrasound spectroscopic parameters over different times during treatment with radiotherapy as predictors of tumour shrinkage and pathologic complete response. Ultrasound parameters investigated will include mid-band fit (related to image intensity),spectroscopic slope (backscatter versus frequency), spectroscopic intercept, histogram fit size and shape parameters which can be used as estimates of scatterer size and concentration.
