Trial Outcomes & Findings for Radiation Therapy During Surgery in Treating Older Women With Invasive Breast Cancer (NCT NCT00182728)

NCT ID: NCT00182728

Last Updated: 2024-10-01

Results Overview

Rates of good/excellent cosmesis was evaluated using the following criteria: Excellent - when compared to the untreated breast, there is minimal or no difference in the size, shape, or texture of the treated breast. There may be mild thickening or scar tissue within the breast or skin, but not enough to change the appearance. Good - there is mild asymmetry in the size or shape of the treated breast as compared to the normal breast. The thickening or scar tissue within the breast causes only a mild change in the shape.

Participant Flow

March 2003 to July 2007

89 patients consented. Of those 89, 18 were not treated for the following reasons: tumor not seen on ultrasound (2), tumor too close to chest wall (7), tumor too large (1), ineligible pathology (1), ineligible nodal status (1), operating room logistical errors (3), patients withdrew (2), not eligible for anesthesia (1).

PRIMARY outcome

Timeframe: 1 year follow up visit

Population: Patients who received intraoperative radiation therapy (IORT) alone. 56 patients were assessed.

Rates of good/excellent cosmesis was evaluated using the following criteria: Excellent - when compared to the untreated breast, there is minimal or no difference in the size, shape, or texture of the treated breast. There may be mild thickening or scar tissue within the breast or skin, but not enough to change the appearance. Good - there is mild asymmetry in the size or shape of the treated breast as compared to the normal breast. The thickening or scar tissue within the breast causes only a mild change in the shape.

PRIMARY outcome

Timeframe: 3 months

Skin and subcutaneous toxicity were graded by a radiation oncologist according to the common terminology criteria for adverse events version 3.0. Toxicities directly, probably, or possibly related to the radiation were included. Grade refers to the severity of the AE. The CTCAE v3.0 displays Grades 1 through 5 with unique clinical descriptions of severity for each adverse event (AE) based on this general guideline: Grade 1 Mild Adverse Event Grade 2 Moderate Adverse Event Grade 3 Severe Adverse Event Grade 4 Life-threatening or disabling Adverse Event Grade 5 Death related to Adverse Event

PRIMARY outcome

Timeframe: 5 years

Population: There were 71 patients who received IORT. Of those 71 patients, 18 received further local therapy due to "high risk" pathology. The results include the 53 patients who received IORT without further local therapy.

Percentage of participants who experienced a ipsilateral breast event (tumor bed recurrence versus elsewhere in breast).
