EXPERIMENTALContura accelerated partial breast irradiation. Following a lumpectomy, a Contura balloon catheter is placed in the lumpectomy cavity. Later that morning, accelerated partial breast irradiation begins.
Interventions
A total radiation dose of 34 Gy is delivered in 10 fractions bid over 5-7 days with 6 hours between the radiation treatments each day. Each radiation treatment takes 15-30 minutes. There is no radioactivity left behind in the patient.
Eligibility Criteria
You may qualify if:
- Able and willing to sign informed consent
- Age 50 or older at diagnosis
- Life expectancy greater than 10 years (excluding diagnosis of breast cancer)
- Surgical treatment of the breast must have been lumpectomy. The margins of the resected specimen must be histologically free of tumor (negative surgical margins per NSABP criteria)
- On histologic examination, the tumor must be DCIS and/or invasive breast carcinoma
- For patients with invasive breast cancer, an axillary staging procedure must be performed \[either sentinel node biopsy or axillary dissection (with a minimum of 6 axillary nodes removed), and the axillary node(s) must be pathologically negative\]
- The T stage must be Tis, T1, or T2. If T2, the tumor must be less than or equal to 3.0 cm in maximum diameter
- Estrogen receptor positive tumor
You may not qualify if:
- Age \< 50 at diagnosis (regardless of histology)
- Pregnant or breast-feeding
- Active collagen vascular disease
- Paget's disease of the breast
- Prior history of DCIS or invasive breast cancer
- Prior breast or thoracic radiation therapy for any condition
- Multicentric carcinoma (DCIS or invasive)
- Synchronous bilateral invasive or non-invasive breast cancer
- Surgical margins that cannot be microscopically assessed or that are positive
- Positive axillary node(s)
- T stage of T2 with the tumor \> 3 cm in maximum diameter or a T stage of T3 or T4
- Estrogen receptor negative tumor
