Post-Mastectomy Surveillance to Detect Recurrence in Breast Cancer Patients

Providence Health & Services100 enrolled

Overview

Currently, there is no standard recommendation for using imaging studies to check patients for breast cancer recurrence who have been treated with mastectomy. The investigator proposes performing in-office ultrasound examinations of these patients to determine if this would be helpful in identifying an expected 5-7% of patients with breast cancer recurrences following mastectomy.

The investigator hypothesizes that surgeon-directed ultrasound is a feasible, accurate, and cost-effective strategy for local recurrence surveillance in breast cancer patients after mastectomy. Toward examining these hypotheses, the investigators propose the following Specific Aims: Aim I: To determine the number of breast cancer recurrences following mastectomy detected by surgeon-performed ultrasound. Aim II: To determine the sensitivity and specificity of surgeon-performed ultrasound for the detection of post-mastectomy breast cancer recurrence. Aim III: To estimate the cost of performing surgeon-directed ultrasound for the detection of post-mastectomy breast cancer recurrence from the perspective of a third party payer relative to standard surveillance alone.

Outcomes

Primary Outcomes

To determine the number of breast cancer recurrences following mastectomy detected by surgeon-performed ultrasound.

To determine the number of breast cancer recurrences following mastectomy detected by surgeon-performed ultrasound during a three year trial period.

Time frame: 3 years

Secondary Outcomes

The sensitivity of surgeon performed breast ultrasound to detect breast cancer recurrence after mastectomy will be measured.

Sensitivity measures the proportion of patients that have pathologically confirmed breast cancer recurrences that were correctly identified as such by surgeon performed ultrasound.

Time frame: 3 years
