QOL-09. QUALITY OF LIFE AFTER SURGERY FOR LOWER GRADE GLIOMAS

Abstract BACKGROUND Limited data exist on long-term quality of life (QOL) for adults diagnosed with lower grade glioma (LGG). METHODS QOL was assessed for 320 adults with LGG (World Health Organization grade 2/3) enrolled in the International Low Grade Glioma Registry using the Medical Outcomes Study 36-Item Short Form (SF-36) health survey. Data on symptoms were also collected. QOL outcomes were examined by treatment group and also compared to those from a population-based case/control study of meningioma (the Meningioma Consortium), in which 1722 meningioma cases diagnosed among residents of Connecticut, Massachusetts, California, Texas, and North Carolina from May 1, 2006 through March 14, 2013 were enrolled and frequency matched to 1622 controls by age, sex and geography. RESULTS The LGG sample average age is 45 years at time of interview and 53.1% male. Almost 55% of patients had received radiation and chemotherapy (primarily temozolomide); 32.4% had received neither treatment. Almost 2/3 LGG subjects report difficulty with speaking, memory, or thinking and over 1/3 report personality change or difficulty driving. After controlling for age and other co-morbidities, individuals diagnosed with LGG report levels of physical, emotional, and mental health functioning below those reported in a meningioma as well as a general healthy population. CONCLUSIONS Despite being relatively young, persons with LGG report significantly reduced QOL compared to persons with non-malignant brain tumors and to a control population, highlighting the need to better acknowledge and manage these symptoms for this group of patients diagnosed in the prime of life.
