Outcomes and Cosmesis With Whole Breast Irradiation and Boost
- Conditions
- Early-stage Breast Cancer
- Interventions
- Radiation: Radiation Therapy
- Registration Number
- NCT06295744
- Lead Sponsor
- University of Wisconsin, Madison
- Brief Summary
This study is being done to evaluate cosmetic, patient-reported outcome measures (PROMs), and toxicities for women undergoing ultra-short whole breast irradiation (WBI) therapy with simultaneous integrated boost (SIB). 50 participants will be on study for up to 60 months.
- Detailed Description
The study population will consist of 50 participants with non-metastatic, early-stage invasive breast cancer or ductal carcinoma in situ (DCIS). Eligible patients will include those with a biopsy proven invasive breast cancer or DCIS, greater than or equal to 18 years of age, undergoing breast conserving surgery and adjuvant radiation therapy at UW Health with an indication for WBI with tumor bed boost. Selection need for boost and radiation treatment field design and pre-tx imaging are at the discretion of the treating provider.
Accrual will occur over 5 years at UW Health. Participants will complete 5 treatment visits and 7 study visits over the course of approximately 5.5 years. Research-related outcome measures - MD assessments (e.g., cosmesis) PROMs, and AEs -- will be assessed prior to treatment start, at the 6-week follow-up visit, as well as at 12-, 24-, 36-, 48- and 60-month follow-up visits. Study participation ends after completion of the 60-month follow-up visit.
Objective
• To assess two-year cosmetic outcomes in patients treated with ultra-short WBI with a SIB.
Secondary Objectives
* To assess PROMs via BREAST-Q in patients treated with ultra-short WBI with SIB.
* To assess acute toxicities in patients treated with ultra-short WBI with SIB.
* To assess late toxicities in patients treated with ultra-short WBI with SIB.
* To assess ipsilateral breast tumor recurrence in patients treated with ultra-short WBI with SIB.
* To assess overall survival (OS) in patients treated with ultra-short WBI with SIB.

- Primary Outcome Measures
Name Time Method Harvard Breast Cosmesis Scale Score up to 2 years post-treatment (treatment ends up to 5 weeks on study) 4-point scale where 1 is excellent, 2 is good, 3 is fair, and 4 is poor.
- Secondary Outcome Measures
Name Time Method Change in BREAST-Q Score baseline, 6 weeks post-RT, 12 months post-RT, 24 months post-RT, 60 months post-RT (treatment ends up to 5 weeks on study) The BREAST-Q questionnaire is scored from 0-100 where higher scores indicate better outcomes in each of 5 domains: Psychosocial Well-Being, Sexual Well-Being, Cancer Worry, Fatigue, and Impact on Work.
Incidence of Acute Toxicities up to 90 days post-RT (treatment ends up to 5 weeks on study) Acute toxicities (including breast dermatitis, induration) will be assessed after final treatment within 90 days of radiation therapy completion using Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
Incidence of Late Toxicities up to 60 months on study Late toxicities (including induration, fibrosis, shrinkage, and telangiectasia) will be assessed greater than 90 days of radiation therapy completion using CTCAE version 5.0
Ipsilateral Breast Tumor Recurrence-Free Survival up to 60 months on study Kaplan-Meier curves will be used to estimate ipsilateral breast tumor recurrence-free survival.
Overall Survival (OS) up to 60 months on study Kaplan-Meier curves will be used to estimate OS.
