The optimal radiotherapeutic management of poor-prognosis (elderly and/or poor performance status) high-grade gliomas (HGG) remains controversial. Hypofractionated radiotherapy (hypoRT) has been shown to be non-inferior to daily conventionally fractionated radiotherapy. This study aimed to assess the compliance to treatment and efficacy of a resource-sparing hypoRT regimen in this subset.


The resource-sparing hypoRT regimen was delivered once weekly (5Gy/fraction) for seven fractions to a total dose of 35Gy in seven fractions over six weeks. Compliance to planned treatment and factors that could potentially influence it were analyzed.


Between January 2004 and October 2009, 63 patients with poor-prognosis HGG (age range 40-78 years; Karnofsky performance score ≤70) were offered resource-sparing hypoRT regimen. Twenty eight of 63 patients completed planned course of treatment giving a treatment compliance rate of 44%. Six (9.5%) patients did not receive even a single fraction of radiation after simulation/planning. Thirty eight patients (60%) received ≥3 fractions and were on treatment for at least two weeks. Performance status (P = 0.05) and grade (P = 0.04) significantly impacted upon compliance. Median overall survival for the cohort of 28 patients who completed planned course of treatment was 7.4 months (95% confidence interval: 4.4-10.5 months).


The treatment compliance to a resource-sparing once-weekly hypoRT regimen in poor-prognosis HGG has been somewhat suboptimal and discouraging, possibly due to the protracted scheduling over six weeks. Over 60% of patients were on treatment for two weeks, suggesting that short-course schedules could more likely ensure compliance.
