Primary care providers’ responses to unsolicited Lynch syndrome secondary findings of varying clinical significance
Genetics in Medicine(2021)
摘要
Purpose How primary care providers (PCPs) respond to genomic secondary findings (SFs) of varying clinical significance (pathogenic, uncertain significance [VUS], or benign) is unknown. Methods We randomized 148 American Academy of Family Physicians members to review three reports with varying significance for Lynch syndrome. Participants provided open-ended responses about the follow-up they would address and organized the SF reports and five other topics in the order they would prioritize responding to them (1 = highest priority, 6 = lowest priority). Results PCPs suggested referrals more often for pathogenic variants or VUS than benign variants (72% vs. 16%, p < 0.001). PCPs were also more likely to address further workup, like a colonoscopy or esophagogastroduodenoscopy, in response to pathogenic variants or VUS than benign variants (43% vs. 4%, p < 0.001). The likelihoods of addressing referrals or further workup were similar when PCPs reviewed pathogenic variants and VUS (both p > 0.46). SF reports were prioritized highest for pathogenic variants (2.7 for pathogenic variants, 3.6 for VUS, 4.3 for benign variants, all p ≤ 0.014). Conclusion Results suggest that while PCPs appreciated the differences in clinical significance, disclosure of VUS as SFs would substantially increase downstream health-care utilization.
