What determines quality of life in patients with vestibular schwannoma?

[OBJECTIVES] Patients with a vestibular schwannoma (VS) experience a reduced quality of life (QoL). The main objective of this study was to determine the strongest predictors reducing physical and mental QoL from the disease-specific Penn Acoustic Neuroma Quality of Life (PANQOL) questionnaire in patients with VS.

[DESIGN] Observational study.

[SETTING] Radboudumc Skull Base Centre, Nijmegen.

[PARTICIPANTS] Patients newly diagnosed with VS between 2014 and 2017 managed with either observation, stereotactic radiosurgery or microsurgery.

[MAIN OUTCOME MEASURES] Quality of life was assessed using the disease-specific PANQOL and general Short-Form (36) Health Survey (SF-36). Multiple linear regression models with PANQOL domains as predictors were used to determine the strongest predictors for SF-36 QoL physical and mental health scores. Standardised beta coefficients (β) were used for ranking.

[RESULTS] A total of 174 patients (50% females, mean age 58.9 years) returned the questionnaires, providing a 69% response rate. Fifteen patients (9%) were treated with microsurgery, 29 (17%) with stereotactic radiosurgery and 130 patients (75%) were observed in a wait and scan strategy. A lack of energy (β = .28; P ≤ .001), lower general health (β = .22; P ≤ .001), headache (β = .16; P ≤ .001), anxiety (β = .15; P ≤ .001) and balance problems (β = .10; P ≤ .001) are the strongest predictors affecting physical health, while mental health is most affected by anxiety (β = .37; P ≤ .001), a lack of energy (β = .34; P ≤ .001), facial nerve dysfunction (β = .07; P ≤ .001), balance problems (β = .04; P ≤ .001) and headaches (β = .04; P ≤ .001).

[CONCLUSION] A lack of energy, anxiety, headache and balance problems are the strongest predictors of both SF-36 physical and mental QoL in patients with VS. More awareness and supportive care regarding energy, anxiety, headache and balance in informing, evaluating and treating patients with VS could improve QoL.
