Using ultrasound spectroscopy to predict radiation treatment response in cancer patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to identify optimal ultrasound spectroscopy parameters that can serve as early indicators of treatment response in patients with prostate, rectal, and head and neck cancers undergoing radiotherapy. By utilizing high-frequency and conventional-frequency ultrasound techniques, the researchers will assess various forms of cell death and correlate ultrasound parameters with tumor response and survival rates. The primary endpoint is to determine the best ultrasound spectroscopy parameter for predicting pathological complete or partial response, while secondary endpoints include tumor size reduction and changes in blood vessel distribution.

Who can join: the full rules

Inclusion Criteria:

* (1) Histologically or cytologically confirmed prostate, rectum and head and neck carcinoma which has not been treated with any first-line therapy and will be treated with radiation therapy
* (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) Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements to be conducted within 7 days prior to dosing:

  (i) hemoglobin \>90 mg/dL (ii) leukocytes \>3,000/mL (iii) absolute neutrophil count \>1,500/mL (iv) platelets \>100,000/mL (v) total bilirubin within normal institutional limits (vi) AST(SGOT)/ALT(SGPT) \<2.5 X institutional upper limit of normal (vii) creatinine within normal institutional limits or creatinine clearance \>60 mL/min/1.73 m2 for patients with creatinine levels above institutional upper limit of normal
* (6) Patients should have the ability to understand and the willingness to sign a written informed consent document. Signed informed consent must be obtained prior to any study specific procedures

Exclusion Criteria:

* (2) Receiving any other investigational agents
* (3) Known brain metastases
* (4) History of allergic reactions attributed to compounds of similar chemical or biologic composition
* (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.
