Trial summary

Radiotherapy is standard treatment for breast cancer after lumpectomy. Although this treatment showed substantial patient benefits and decrease of local recurrence and deaths from breast cancer, it also results in some severe late side-effects, such as skin fibrosis and cardiac failure.

About this study

Radiotherapy is standard treatment for breast cancer after lumpectomy. Although this treatment showed substantial patient benefits and decrease of local recurrence and deaths from breast cancer, it also results in some severe late side-effects, such as skin fibrosis and cardiac failure. It's possible to offer breast irradiation (RT) and minimizing toxicities radiation dose to skin, lung and heart. This will be achieved with highly conformal RT delivery using Tomotherapy. We plan to evaluate this approach in clinical study. We plan also to evaluate the value of genomic, cellular and functional imaging endpoints as predictive markers of toxicity in our breast cancer population. This program is expected to prospectively validate that Tomotherapy for breast RT can decrease skin, lung and heart toxicities and maintaining excellent cancer control after lumpectomy.

Read the detailed description

Radiotherapy is standard treatment after conservative surgery for early-stage breast cancer. Although this approach substantially improves local control and reduces deaths from breast cancer, it also results in some severe late side-effects, including skin fibrosis, deaths from radiation-induced cardiac disease and lung cancer. We will undertake a novel approach to the evaluation of radiation-induced toxicity during and after whole breast irradiation (RT) following breast-conserving surgery, with the long-term strategic goal of minimizing RT toxicity in early breast cancer. Theoretically, it is possible to achieve this goal through very highly conformal RT delivery and avoidance of RT in toxicity-prone individuals where possible. We plan to evaluate the utility of genomic analysis, cellular DNA repair competence, and functional imaging endpoints as predictive markers of toxicity in our breast cancer population. This program is expected to (a) prospectively validate that HT for breast RT can decrease acute toxicity whilst maintaining excellent cancer control after BCS; (b) demonstrate that novel surrogate markers will aid in the prediction of acute and/or late normal tissue toxicity with a view to identify toxicity-prone (or conversely, robust) individuals from amongst the breast cancer population.

Questions about this trial

What is this clinical trial studying?

An observational study of Genetic Markers and Cardiac Toxicity, run by AHS Cancer Control Alberta 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 4 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: stopped early, as of the sponsor's last update on 24 Feb 2016. 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?

The study was stopped early (reason given: accrual goal met). Results are not available in the source record.

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?

skin and cardiac toxicity (time frame: 24 months post RT). 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 24 Feb 2016.
