简要总结
The purpose of this study is to create a registry to evaluate the use of intra-operative radiation therapy (IORT) and to study the efficacy and toxicity of breast radiotherapy given intra-operatively as a single fraction after breast conserving surgery,
详细描述
A registry trial has been designed and modeled after the original successful TARGIT protocol, to continue the use of IORT for a select population of women, and to follow outcomes with regards to local and regional control, toxicity and morbidity. Patients selected for breast conserving surgery, who are considered to have a low risk of local recurrence, are eligible for this registry trial once their informed consent is obtained. This single arm cohort study allows entry of patients who have been diagnosed with early stage breast cancer and whose clinical stage is suitable for treating conservatively (small tumor and no gross nodal involvement). Tumors should not be more than 3.5 cm in size.

结局指标
主要结局
In-breast local failure and patterns of in-breast failure
时间窗: 6 months after IORT through year 10
In-breast local failure is defined as recurrence of cancer in the ipsilateral (same side) breast. Following IORT, patients will be monitored every 6 months for 3 years, and then annually in years 4 and 5 to determine if cancer has returned. In years 6 through 10 medical records will be reviewed to obtain information on participants' breast cancer status.
