Brief summary

Accelerated Partial Breast Irradiation by Mammosite and intensity modulated radiotherapy is safe and effective in patients with early stage breast cancer resected by lumpectomy.

Interventions

RADIATIONBreast Brachytherapy with Mammosite RTS

Treatment will be performed using high dose rate brachytherapy, starting between 2-5 days of implant, 34 Gy at 1 cm in 3.4 Gy fractions BID for 5 treatment days with typical boost dose od 10 Gy given in 2 fractions at least 6 hours apart.

RADIATIONIntensity Modulated Radiotherapy

Accelerated Partial Breast Irradiation using intensity modulated radiotherapy, a novel planning and delivery technique for external beam radiation

Inclusion criteria

* Be a Tis, T1, N0, M0 AJC Classification * Have negative surgical margins (\> or = 2 mm) after final surgery * Should have adequate skin spacing between balloon surface and surface the skin (\> 7 mm)\* * Patients with infiltrating lobular histologies should have breast MRI scanning as part of the initial staging to verify localized T1, or Tis disease * Multifocal findings (define as 2 or more breast quadrants) on MRI scanning should be further evaluated by ultrasound and, if necessary biopsy, to exclude multiquadrant disease.
