Impact of subjective and objective language function and psychological distress on quality of life in glioma patients awaiting surgery

Abstract

ABSTRACT Background Maintaining quality of life (QoL) and identifying contributing factors is an important aspect of treatment for glioma patients. Little is known about to what extent language function and psychological distress impact QoL before surgery. Aims The aim of the present study was to investigate the impact of subjective and objective language function, as well as psychological distress on domains of QoL before surgery. Methods and procedures Twenty-seven patients (52% female) with a suspected glioma, grade 1‒3 based on symptoms and MRI imaging diagnostics were assessed pre-surgery. Subjective language concerns, psychological distress and QoL were investigated with self-reported questionnaires. A Subjective language index was calculated, based on items addressing word-finding, expression of thoughts, reading and writing. Objective language function was assessed with tasks of naming (The Boston Naming Test), verbal comprehension (Vocabulary and Similarities), verbal fluency (Semantic and Phonemic fluency) and verbal short-term and working memory (Digit span forward and backward). The strength of associations was determined using Spearman’s rho correlations. Linear regression analyses were used to examine predictors for QoL. Outcomes and Results Clinically significant reductions in QoL were found in 48% of the sample. Subjective language concerns were highly common, with 85% reporting some degree of difficulty. Group means on objective language tests were within normative range on the included measures. The Subjective language index correlated significantly with several QoL domains, whereas objective performance mainly correlated with functional well-being. Psychological distress was a strong predictor for QoL. Conclusions The findings demonstrate that reductions in QoL may occur during the diagnostic phase, even before glioma treatment starts. Subjective language concerns and psychological distress contributed to all aspects of QoL and highlight the importance of acknowledging patient-reported information. The results suggest a comprehensive multi-modal assessment of glioma patients pre-surgery, to establish a base-line and facilitate patient-centered treatment planning.
