Conditions

Prostate Cancer Head and Neck Cancer Rectal Cancer

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

(2) Measurable disease by ultrasound, or MRI performed within 28 days prior to treatment
(3) Eastern Co-operative Oncology Group (ECOG) Performance Status of 0 or 1
(4) Life expectancy of at least 6 months

(5) Contraindications to radiotherapy such as but not limited to:
(i) previous radiotherapy to an involved area (ii) active collagen vascular disease (iii) genetic diseases associated with hyper-radiosensitivity
(6) Any clinically serious infections requiring systemic anti-bacterial, antifungal or antiviral therapy
(7) Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, and cardiac arrhythmia
(8) Psychiatric illness/social situations that would limit compliance with study requirements
(9) History of active ongoing seizure disorder, substance abuse, medical, psychological or social conditions that may interfere with the patient's participation in the study or evaluation of the study results
(10) Any condition that is unstable or could jeopardize the safety of the patient and their compliance in the study.

Interventions

DEVICEUltrasound 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.
