Clinical Trial Summary

RATIONALE: Multi-faceted provider education and decision support intervention will increase the rate of appropriate referral of breast cancer patients at increased risk for hereditary breast and ovarian cancer (HBOC) to genetic counseling. PURPOSE: This cluster randomized controlled trial will compare active and passive interventions to increase the rate of appropriate genetic counseling referrals of newly diagnosed breast cancer patients at increased risk for HBOC to genetic counseling in the community oncology setting.

Description:

Approximately 5-10% of all breast cancer patients have hereditary breast cancer, the majority due to an inherited mutation in the BRCA1 or BRCA2 genes (BRCA mutation carriers). Breast cancer patients who are BRCA mutation carriers have up to a 65% risk for a new primary breast cancer in the future. Additionally, BRCA mutation carriers have a 10-45% lifetime risk for ovarian cancer. Effective options to decrease these high future cancer risks are available to breast cancer patients who learn they carry a BRCA mutation - including prophylactic mastectomy and oophorectomy. Prophylactic mastectomy and oophorectomy reduce the risks for future primary breast cancer and ovarian cancer, respectively, by more than 90%. Because of the high risks for future cancer and the opportunity for effective risk reduction among mutation carriers, national guidelines consistently recommend referral of breast cancer patients at increased risk for hereditary breast cancer and ovarian cancer (HBOC) to genetic counseling by a qualified genetics professional. Lack of implementation of this standard of care constitutes an error of omission and jeopardizes patient outcomes. We propose a cluster randomized controlled trial to compare a "passive intervention" - dissemination of professional guidelines - with an "active intervention" - a multi-faceted provider education and decision support intervention to improve 1) appropriate referral of breast cancer patients at risk for HBOC to genetic counseling in the community cancer center setting and 2) pre-surgical referral among newly diagnosed patients. Ultimately, these results will lead to decreased breast and ovarian cancer incidence and mortality among breast cancer patients and their family members, as well as improved outcomes of and satisfaction with surgical decision-making.

Eligibility

Participant Inclusion Criteria:

• Females 18 years of age or greater
• Newly diagnosed primary breast cancer prior to initial definitive surgical treatment, including In situ and Invasive cancer, Stages 0 - III. Pathologic confirmation of diagnosis is required.
• Able to read and write in English or Spanish

Participant Exclusion Criteria:

• Any previous diagnosis of cancer except for non-melanoma skin cancer

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rate of appropriate referral of newly diagnosed breast cancer patients at increased risk for HBOC to genetic counseling in Active vs. Passive Intervention Clusters	Site providers will be randomized and receive either the active or passive genetic counseling intervention. Post intervention, site providers will maintain a database of all newly diagnosed breast cancer patients that meet the study eligibility criteria. One year post diagnosis, subjects will be mailed an informed consent form including questionnaires from their providers. Returned patient questionnaire data along with information provided directly from site providers will be utilized to determine the rate of appropriate referral for genetic counseling.	1 year post diagnosis
Secondary	Rate of appropriate referral of newly diagnosed breast cancer patients at increased risk for HBOC to genetic counseling in Active vs. Passive Intervention Clusters	Secondary outcomes will be assessed by patient questionnaire and medical record documentation, where appropriate, and include evaluation of: The rate of pre-surgical referral of appropriate patients to genetic counseling; The rate of referral of newly diagnosed breast cancer patients who are not appropriate for genetic counseling referral; The rate of genetic counseling uptake; The rate of bilateral mastectomy, including the rate of bilateral mastectomy among patients receiving different genetic test results; Psychosocial outcomes: Perceived risk for future primary breast cancer and for ovarian cancer will be assessed; Knowledge of hereditary breast and ovarian cancer will be measured; Cancer-related distress will be assessed using answers from the patient questionnaire; Satisfaction with the decision regarding surgical treatment will be assessed; Provider knowledge outcomes from the educational session will also be assessed	12-15 months post diagnosis
