First report of quality of life in adults with neurofibromatosis 2 who are deafened or have significant hearing loss: results of a live-video randomized control trial.

PURPOSE: To test the feasibility, acceptability, and preliminary efficacy of a mind-body program for patients with neurofibromatosis 2 (NF2) who are deaf or have significant hearing loss (d3RP-NF2) against an attention placebo control (dHEP-NF2) in a single-blind randomized control trial. Both were delivered using Communication Access Real-Time Translation and live group videoconferencing.

METHODS

Forty-five adults with NF2 were randomized. Co-primary outcomes were physical quality of life (QoL) and psychological QoL and secondary outcomes were social QoL and environmental QoL, all measured with the World Health Organization Quality of Life Abbreviated Instrument (WHOQOL-BREF). Assessments were conducted at baseline, post-treatment, and six-month follow-up.

RESULTS

Forty-one participants (91%) completed the intervention, and 29 (64%) completed the six-month follow up. Participants in the d3RP-NF2 showed significantly greater improvements from baseline to post-treatment on physical QoL (14.79, 95% CI 5.41-24.18; p ≤ 0.001), psychological QoL (18.77, 95% CI 7.09-30.44, p ≤ 0.001), and environmental QoL (13.25, 95% CI 1.10-25.39, p = 0.03) compared to the dHEP-NF2. Social QoL also significantly increased in the d3RP-NF2 (16.32, 95% CI 6.66-25.97, p = 0.001), but improvement was not beyond the dHEP-NF2. Gains in QoL were clinically meaningful and maintained at the 6-month follow-up for d3RP-NF2 participants across all QoL domains. There were more treatment responders in the d3RP-NF2 compared to the dHEP-NF2.

CONCLUSIONS

The d3RP-NF2 was well accepted, highly feasible, and resulted in sustained improvements in QoL in patients with NF2 who are deaf or have significant hearing loss.
