About this study
Official title: A Study to Correlate Ultrasound Elastography With Histopathology to Monitor the Response of Locally Advanced Breast Cancer to Neoadjuvant Chemotherapy.
This research proposal concerns a study to monitor the effects of chemotherapy on breast cancer tumour and peritumour stromal cells using ultrasound (US) elastography (also known as strain imaging).
Many cancer treatments currently being developed are targeted; that is they exploit particular biological processes in specific cancer cell types to disrupt tumour growth. Being able to monitor the efficacy of these typically high-cost drug therapies is essential both for the best patient outcome as well as offering economical benefits to the health care system and much needed insight into future drug development.
Read more
Ultrasound provides a relatively inexpensive, non-invasive means for imaging cancers, and has been used widely in breast cancer diagnosis for many years. Its role in therapy monitoring has been suggested but has not been well explored. The purpose of this proposal is to explore this potential in more depth.
It has been identified that significant interaction takes place between tumour and stroma through all stages of tumour growth; this complex relationship is an ongoing topic of research. Fibrotic changes occur during tumour growth and are also a quintessential process of healing. Indeed, fibrosis is a common after effect to chemotherapy in many forms of cancer. Elastography is an established imaging technique (based on ultrasound or MRI) which can estimate the relative stiffness of tissues in vivo and is thus well-suited to monitor these particular biological processes.
This elucidates the main hypothesis of this project: fibrosis, cancer cell necrosis and inflammation may all contribute to a measurable response in elastography. These changes to the tissue composition can be imaged over a course of a patient's treatment to assess the response to chemo/hormonal therapy.
The ultimate project goals are to develop a clinical tool (based on ultrasound elastography) to improve treatment management in addition to offering a better biological understanding of tumour/stroma behaviour.

What is being measured
The primary outcome is the main question the study is designed to answer.
The ratio of average stiffness measured within the tumour over average stiffness measured in the stroma
Tissue stiffness will be used to assess a patients response to chemotherapy
Measured: Patients will be followed over the course of chemotherapy treatment, an expected average of 18 weeks

Questions about this trial
What is this clinical trial studying?
An observational study of Breast Cancer and Neoadjuvant Therapy, run by Oxford University Hospitals NHS Trust.
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 9 inclusion and 3 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: finished, as of the sponsor's last update on 12 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The ratio of average stiffness measured within the tumour over average stiffness measured in the stroma (time frame: Patients will be followed over the course of chemotherapy treatment, an expected average of 18 weeks). 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 Oct 2017.
