However, little is known about the disclosure processes or screening behaviors of individuals who receive inconclusive genetic test results. This study compared endoscopy use and disclosure between individuals with positive and inconclusive genetic test results, within a year after results were received.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS:<\/jats:title><jats:p>Individuals with a personal history of cancer and suspected of having HNPCC participated in genetics education and counseling, underwent HNPCC testing, and received genetic test results (GCT) within a prospective cohort study. Demographic, psychosocial, and behavioral data were obtained from questionnaires and interviews completed before and after GCT.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS:<\/jats:title><jats:p>Index cases with inconclusive genetic test results were less likely to screen within 12 months. Index cases who disclosed test results to children within 6 months were more likely to screen within 12 months, controlling for mutation status. Index cases with inconclusive genetic test results were less likely to share results with a healthcare provider within 6 months. Index cases who disclosed genetic test results to healthcare providers within 6 months were more likely to have endoscopy within 12 months.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS:<\/jats:title><jats:p>Genetic test results and disclosure significantly affected colon cancer screening at 12\u2010month follow\u2010up. Interventions to improve adherence to colorectal cancer screening should consider increased education of those receiving inconclusive results and encourage disclosure to healthcare providers and family members.
