Overview
The hypothesis is that the daily use of brass mesh bolus achieves a comparable dose to every-other-day use of Superflab bolus (current standard of care) in chest wall post-mastectomy patients treated with rotational 6 MV photon delivery.
Description
Intervention: During a standard-of-care 15 fraction radiotherapy treatment, a brass mesh bolus will be used for a single fraction. Small in-vivo dosimeters will be used for three treatment fractions to measure and compare skin doses for quantification purposes.
Comparator: Superflab and no bolus applied as per the treating physician's practice, typically on alternate days. The intervention and comparator tools are to be utilized on each participant.
Primary outcome
- To determine the skin dose under brass mesh bolus and compare it with the skin dose under Superflab bolus (current standard of care).
- To determine the number of fractions for which brass mesh bolus should be used to achieve an acceptable skin dose.
Eligibility
Inclusion Criteria:
Women undergoing rotational chest wall radiotherapy following mastectomy for breast cancer
treatment who would utilize Superflab bolus on some, but not all, days of radiotherapy
treatment.
Exclusion Criteria:
Patients who require daily bolus due to skin involvement or other high-risk features
requiring a high skin dose will not be included.
