Conditions
Brief summary
This trial studies the acceptability and how well decision making tool works in supporting decision making in contralateral prophylactic mastectomy in patients with newly diagnosed breast cancer. Decision making tool may help patients with early stage breast cancer make decisions regarding their surgical options.
Detailed description
PRIMARY OBJECTIVES: I. An online decision support tool will be field tested that provides patients facing a decision about contralateral prophylactic breast cancer (CPM) with evidence-based information about the expected incidence of contralateral breast cancer and the life expectancy benefit of CPM. The tool will be designed for use in clinical settings and viewed jointly by the patient and physician as part of a shared decision making process around CPM. OUTLINE: Patients use decision making tool during consultation with breast cancer surgeon and complete questionnaires before and after consultation.

Eligibility
Inclusion criteria
* Newly diagnosed ductal breast carcinoma in situ (DCIS) or stage I-III sporadic unilateral invasive breast cancer * Able to speak read or write English
Exclusion criteria
* Patients with previous breast cancer * Prior history of bilateral prophylactic mastectomy * Known to have a germline mutation that predisposes them to an increased risk of breast cancer (e.g. BRCA1/2) and/or they are considered at high risk for contralateral breast cancer on the basis of a strong family history of cancer
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Acceptability of the decision support tool | Up to 2 years | Patients' rating of the acceptability of the decision support tool will be assessed using questions from the Ottawa Acceptability Measures, including the clarity, amount, and balance of the information provided by the tool. Acceptability data from patients enrolled in the field test will be reported descriptively. |
| Changes in patient's knowledge of contralateral prophylactic mastectomy (CPM) | Baseline up to 2 years | Will test for change in knowledge from before to after administration of the decision support tool with a breast cancer surgeon using paired samples t-tests. |
| Reductions in decisional conflict about CPM | Baseline up to 2 years | Will be assessed using the Decisional Conflict Scale. Will test for reduction in decisional conflict from before to after administration of the decision support tool with a breast cancer surgeon using paired samples t-tests. |
