Accelerated Partial Breast Irradiation Following Lumpectomy for Breast Cancer
This trial is active, not recruiting.
|Conditions||breast cancer, carcinoma, ductal|
|Treatments||intra-operative radiotherapy (iort), lumpectomy, whole breast radiotherapy, intracavitary brachytherapy, accelerated external beam 3-d conformal radiotherapy, stereotactic apbi|
|Start date||September 2002|
|End date||March 2029|
|Trial size||400 participants|
|Trial identifier||NCT00185744, 78466, BRSNSTU0003, IRB-13807|
To determine whether an accelerated course of radiotherapy delivered to the lumpectomy cavity plus margin using IORT as a single dose, intracavitary brachytherapy with the MammoSite device over 5 days, partial breast 3-D CRT in 5 days, or stereotactic APBI over 4 days is a feasible and safe alternative to a six and a half week course of whole breast radiotherapy. The study will measure both short and long-term complications of radiation treatment, short and long-term breast cosmesis, local rates of in-breast cancer recurrence, regional recurrences, distant metastases, and overall survival.
|Endpoint classification||safety/efficacy study|
|Intervention model||parallel assignment|
In-breast tumor recurrence (IBTR)
time frame: 20 years

Greater than 12 weeks since definitive surgical excision or completion of chemotherapy 13. Involved lymph nodes detected by frozen section or touch preparation at time of lumpectomy 14. Patients with 1 to 3 positive lymph nodes determined postoperatively (does not include patients with micro-metastases) 15. Subglandular or submuscular breast implants (does not include patients having implants placed AFTER intra-operative radiotherapy)
