Description
PRIMARY OBJECTIVE:
I. Evaluate the effectiveness and sustainability of heritable cancer syndrome testing in two proposed screening populations compared to current guidelines.
SECONDARY OBJECTIVES:
I. Measure adherence to current guidelines for screening and prophylactic intervention of Cohorts B and C compared to Cohort A to show non-inferiority.
II. Measure the efficiency of cascade testing (defined as the ratio of family members screened over total possible) for Cohorts B and C compared to Cohort A to show non-inferiority.
III. Determine the costs and effectiveness, specifically quality adjusted life years (QALYs) associated with genetic screening models based on Cohorts B and C to estimate incremental cost-effectiveness ratio (ICER) and show that the costs per QALY are below the acceptable cost effectiveness threshold.
OUTLINE:
Patients undergo collection of saliva samples for genetic testing. If genetic test is positive, patients receive genetic counseling. Patients also complete a survey about cancer prevention, screening, and treatment.
