Introduction: With improvements in overall and progression-free survival in gliomas, current focus in neurosurgical oncology has largely shifted to the issue of quality of life (QOL) after treatment. There are not too many prospective studies evaluating QOL in these patients. We prospectively analyzed the health related quality of life (HRQOL) using the short form (SF) 36 questionnaire among patients harbouring a supratentorial glioma who underwent surgery at a tertiary care center in India. Methods: HRQOL was evaluated prospectively in 103 patients, between May 2016 and November 2017, at Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow. Score improvements were evaluated in terms of the smallest difference that a patient perceived to be clinically beneficial. The responsiveness of scores was assessed as minimum clinically important difference (MCID), effect size (ES) and relative efficiency. Cronbach's alpha co-efficient was used to assess the reliability of the result obtained. Results: The mean pre-operative score was the highest in the mental health domain (50.21±21.45) and significantly lower in patients with raised intracranial pressure (ICP), pre-operative deficits, a poor Karnofsky performance scale (KPS) score, in large tumors (>4cm) located in an eloquent location and in deep-seated tumors. A significant improvement was noted across all domains except the physical role (P-value 0.20). Overall, the general health domain was most responsive to change with the largest t-value (6.56) and 55.7% patients achieved their target MCID in general health (GH) domain. Among all the factors studied, only a low baseline SF-36 score was significantly associated with a change in QOL after surgery. Conclusion: Most parameters of HRQOL improved following surgery. Only small-to-moderate improvements occured in the early follow-up period. Large improving trends were noted on a long-term basis, irrespective of the histo-pathological grade. Similar improvements were also noted in patients who subsequently underwent re-surgery despite the development of post-operative complications or new deficits. Also, a low baseline QOL score heralded a poor survival.
