Abstract Background Radiofrequency ablation (RFA) of neuromas has emerged as a potential treatment option for refractory neuroma‐associated postamputation pain (PAP). Objective To evaluate the feasibility of using internally cooled radiofrequency ablation (C‐RFA) for treating neuroma‐associated PAP. Design Prospective single‐arm pilot study. Setting Tertiary academic medical center. Participants Eight participants with neuroma‐associated PAP (mean age 56.5 [ interquartile range, 50.5–68.5] years; mean body mass index 30.2 [ interquartile range, 26.3–34.8] kg/m 2 ). Intervention Participants were recruited and treated with C‐RFA between 2019 and 2023. Main Outcome Measures Pain and functional outcomes were assessed at 1, 3, 6, and 12 months after C‐RFA using Numeric Rating Scale (NRS), Groningen Activity Restriction Scale (GARS), Patient Global Impression of Change (PGIC), and Medication Quantification Scale III (MQS‐III). Responder definitions for each outcome measure were ≥50% NRS reduction, ≥30% GARS improvement, ≥6 on PGIC, and ≥6.8‐point MQS‐III reduction. Results NRS responder rates at 1, 3, 6, and 12 months were 25.0% (95% CI, 7.0%–59.1%), 50.0% (95% CI, 21.5%–78.5%), 37.5% (95% CI, 13.7%–69.4%), and 50.0% (95% CI, 21.5%–78.5%), respectively. Responder rates for GARS were 25.0% (95% CI, 7.1%–59.1%) at 1 month and 12.5% (95% CI, 2.2%–47.1%) at 3, 6, and 12 months. The proportion of PGIC responders was 37.5% (95% CI, 13.7%–69.4%) at 1 and 3 months and 12.5% (95% CI, 2.2%–47.1%) at 6 and 12 months. MQS‐III responder rates were 25.0% (95% CI, 7.1%–59.1%) at 1 month, 12.5% (95% CI, 2.2%–47.1%) at 3 months, and 37.5% (95% CI, 13.7%–69.4%) at 6 and 12 months. There were no complications associated with the C‐RFA procedure. Conclusions These findings indicate the feasibility of neuroma C‐RFA as a treatment for refractory neuroma‐associated PAP but also suggest that further patient selection and C‐RFA technique optimization are warranted before investigating this treatment paradigm in a larger prospective study.

Efforts to characterize stakeholder attitudes about the implementation of genomic medicine would benefit from a validated instrument for measuring public views of the potential benefits and harms of genomic technologies, which would facilitate comparison across populations and clinical settings. We sought to develop a scale to evaluate attitudes about the future of genomic medicine. We developed a 21‐item scale that examined the likelihood of various outcomes of genomic medicine. The scale was administered to participants in a genomic sequencing study. Exploratory factor analysis was conducted and bivariate correlations were calculated. The genomic orientation (GO) scale was completed by 2895 participants. A two‐factor structure was identified, corresponding to an optimism subscale (16 items, α = 0.89) and a pessimism subscale (5 items, α = 0.63). Genomic optimism was positively associated with a perceived value of genetic test results, higher health literacy, and decreased decisional conflict about participation in a genomic research study. Genomic pessimism was associated with concerns about genetic testing, lower health literacy, and increased decisional conflict about the decision to participate in the study. The GO scale is a promising tool for measuring both positive and negative views regarding the future of genomic medicine and deserves further validation.
