What to Expect as a Participant

This is an observational study. You will not receive an experimental treatment; researchers will collect data based on your existing condition or standard treatment.

This trial targets 320 participants in total. It began in 2014-12-17 with a primary completion date of 2025-12-17.

Brief 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

Eligibility Criteria
