About this study

Official title: Pilot Investigation of Ultrasound Imaging and Spectroscopy and Ultrasound Imaging of Vascular Blood Flow as Early Indicators of Breast Cancer Response to Neoadjuvant Treatment

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 objectives of this study are to evaluate the use of ultrasound imaging and spectroscopy as a predictive marker of advanced tumour response to combined chemotherapy and radiotherapy. Since neoadjuvant treatments may also act on tumour vasculature to "normalize" it we will also evaluate blood-vessel imaging by standard Doppler-imaging and with standard higher-resolution imaging using clinically approved microbubble contrast agents.

The main goal, as described above, is to select the best ultrasound spectroscopy parameter to use as an early predictor of pathological complete response.

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 objectives of this study are to evaluate the use of ultrasound imaging and spectroscopy as a predictive marker of advanced tumour response to combined chemotherapy and radiotherapy. Since neoadjuvant treatments may also act on tumour vasculature to "normalize" it we will also evaluate blood-vessel imaging by standard Doppler-imaging and with standard higher-resolution imaging using clinically approved microbubble contrast agents.

The main goal, as described above, is to select the best ultrasound spectroscopy parameter to use as an early predictor of pathological complete response.

Specifically, we will as a primary endpoint correlate changes in ultrasound backscatter parameters obtained throughout the course of treatment with pathological complete, partial, or complete and partial response. We ultimately hope to be able to generate a Receiver-Operator-Curve for each parameter beyond this pilot investigation. The ultrasound-spectroscopy parameters to be examined include mid-band fit, spectral-slope and histogram-distribution-fit parameters related to scatterer size and concentration. From these various receiver-operator curves the best ultrasound parameter for predicting response will be selected and will aid to define the clinical specificity and sensitivity of the technique.

The secondary endpoint in this study will include examining the change in size of the tumour, which will also be measured using conventional gold-standard B-scan ultrasound imaging (length by width by height in addition to volume) and correlating that to the spectroscopic ultrasound changes determined at different times during patient treatment.

Other secondary endpoints will include measuring changes in blood vessel distribution by standard Doppler-imaging and standard microbubble contrast agent imaging. As another secondary endpoint we will also correlate our ultrasound changes with 2 and 5-year long-term clinical outcome.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The primary Outcome will be correlate changes in ultrasound backscatter parameters obtained throughout the course of treatment with pathological complete, partial, or complete and partial response.

    Ultrasound spectroscopy parameters to be examined include mid-band fit parameters, spectral slope and histogram distribution fit parameters related to scatterer size and concentration. From these various receiver-operator curves, the best ultrasound parameter predictive response will be selected and will aid to define the clinical specificity and sensitivity of The technique.

    Measured: 2 and 5-year long-term clinical outcome

Secondary outcomes (2)
  1. The secondary Outcome of this study will include examining the change in tumor size.

    The change in tumor size, which It will also be measured using conventional gold standard B-scan ultrasound images (length by width by height in addition to volume) and correlating it with spectroscopic ultrasound changes determined at different times during the patient's treatment.

    Measured: 2 and 5-year long-term clinical outcome

  2. Other secondary Outcome will include measuring changes in the blood vessels distribution in the tumor.

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer Invasive, run by Sunnybrook Health Sciences Centre at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 12 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Gregory J. Czarnota (416-480-5329, Gregory.Czarnota@sunnybrook.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The primary Outcome will be correlate changes in ultrasound backscatter parameters obtained throughout the course of treatment with pathological complete, partial, or complete and partial response. (time frame: 2 and 5-year long-term clinical outcome). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Dec 2023.
