Other: Cardiac SPECT perfusion scan
A SPECT cardiac perfusion scan provides a three-dimensional map of blood flow to the heart tissue. The scan will be taken at rest only. |
- Changes in cardiac perfusion [ Time Frame: 6-months post radiation ]Cardiac perfusion will be assessed using SPECT cardiac perfusion scans pre- and 6 months post-radiation. Any post-radiation summed-rest score (SRS) > 0 will be counted as a perfusion defect in the calculation of the perfusion defect rate.
- Wall-motion abnormalities [ Time Frame: 6-months post-treatment ]The incidence of wall-motion abnormalities will be assessed using SPECT in the same 12 segment scoring system used to quantify perfusion. Wall-motion abnormalities will be recorded as present or absent in each cardiac segment. When present, wall-motion abnormalities wil be classified as gypokinetic, akinetic, or dyskinetic. The extent of wall involvement (small or large portion) will be described as mild or severe.

Ages Eligible for Study: | 18 Years to 99 Years (Adult, Older Adult) |
Sexes Eligible for Study: | Female |
Accepts Healthy Volunteers: | No |
Sampling Method: | Non-Probability Sample |
Inclusion Criteria:
- signed an Institutional Review Board (IRB)-approved informed consent document for protocol
- age >= 18 years
- histologically confirmed left-sided breast cancer scheduled to undergo curative intent radiation treatment post lumpectomy or mastectomy
- stage 0-III left-sided breast cancer (including DCIS)
- SPECT score of 0 at baseline
- radiation oncologist agrees target volume coverage will not be compromised via use of the DIBH technique along with conformal field shaping
Exclusion Criteria:
- active cardiac disease, defined as a history of angina, arrhythmias, myocardial infarction, congestive heart failure, or any other cardiac condition, which in the opinion of the treating physician would make this protocol unreasonably hazardous for the patient
- symptomatic pulmonary disease currently requiring regular medication including but not restricted to bronchodilators
- concurrent chemotherapy
- prior receipt of mediastinal radiation therapy
- pregnant or lactating women
- inability to understand and follow breathing instructions for the DIBH procedure
