Health-related Quality of Life Assessment in Patients with Malignant Gliomas

Abstract

Background: High-grade gliomas have limited time of survival despite aggressive treatment. Patients experience a decline in their physical and mental capacities, affecting their quality of life (QoL), and require proper therapeutic strategies.

Objective: To assess the QoL of malignant glioma patients before and after the treatment in a longitudinal study of six months.

Methods and Material: Forty-nine patients who were pathologically diagnosed with glioblastoma and anaplastic glioma according to WHO 2016 were included in this prospective study. The assessment of quality of life was done using the European Organization for Research and Treatment of Cancer (EORTC) quality of life (QoL) questionnaire core-30 prior to surgery, 1 and 5 months after the operation.

Results: The decline in Karnofsky scores of the patients was statistically significant. Among the symptom scales, fatigue was more prominent after surgery while pain was noticeable during chemotherapy which was correlated with increased age. The mean overall QoL scores showed a clinically significant decline during the postoperative period. The functional scores demonstrated a significant decline in between all periods. Sex was significantly correlated with preoperative emotional and physical functioning. The patients with right-sided lesions had higher mean scores for social and cognitive functioning.

Conclusions: Low KPS, older age, and female gender may affect cancer symptoms and physical and social activities in malignant glioma patients. Cognitive functions as well as social and occupational roles gradually decline during the first six months of treatments. Overall QoL of high-grade glioma patients deteriorates especially after radiotherapy and during the first months of chemotherapy.
