Official title

A Phase II Study of Accelerated 3 Fraction Photon and Proton Partial Breast External Beam Radiotherapy and Partial Breast Brachytherapy for Early Invasive and Noninvasive Breast Cancer

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is an open label phase II study to determine the safety and efficacy of a novel 3 fraction daily dosing regimen for accelerated partial breast irradiation (APBI) for early invasive and noninvasive breast cancer. The three techniques utilized are recognized as standard options for the delivery of APBI, and there is no evidence that either technique is superior or inferior to any other. The APBI technique utilized will be at the physician's discretion and will be based on technical considerations, availability at the treating radiation facility, insurance coverage, as well as patient preference.
