Quality of Life in Vestibular Schwannoma Patients: A Longitudinal Study.

Abstract

OBJECTIVE\nTo examine differences in quality of life in patients with vestibular schwannoma following a single treatment modality: observation, stereotactic radiosurgery (SRS), or microsurgery.\n\n\nSTUDY DESIGN\nRetrospective review.\n\n\nSETTING\nTertiary academic medical center.\n\n\nPATIENTS\nPatients diagnosed with sporadic vestibular schwannoma who had completed at least 2 Penn Acoustic Neuroma Quality of Life (PANQOL) surveys.\n\n\nINTERVENTIONS\nTreatment via SRS, microsurgery, or observation.\n\n\nMAIN OUTCOME MEASURES\nPANQOL total survey and subdomain scores.\n\n\nRESULTS\nOne hundred and thirty-four patients (94 observations, 24 SRS, 16 microsurgeries) were included. The mean number of PANQOL surveys completed was 2.8 (range 2-5). The total PANQOL scores were significantly lower in the SRS group, but not the microsurgery group, compared with observation at the time of diagnosis (observation 550.4\u200a±\u200a58.4; SRS 471.4\u200a±\u200a37.4; microsurgery 492.6\u200a±\u200a40.7; p\u200a=\u200a0.03). Over time, there were no significant differences in the change of PANQOL scores across the 3 groups (SRS PANQOL score worsened 6.8/year compared with observation, p\u200a=\u200a0.3; microsurgery PANQOL score worsened 7.8/year compared with observation, p\u200a=\u200a0.5). Anxiety was the only subdomain that significantly worsened over time in the microsurgery group (microsurgery PANQOL score worsened 3.8/year compared with observation; p\u200a=\u200a0.009).\n\n\nCONCLUSION\nDespite differences in PANQOL scores at baseline, changes in total PANQOL score over time were not found to be statistically significant, regardless of the treatment group chosen. Overall, these results hold implications for patient counseling when considering treatment choice and quality of life predictions.
