Keywords: glioblastoma multiforme, radiotherapy, hypofraction, prognostic factors
Since long lasting tumor control and survival can not be achieved with coventional radiotherapy in patients with glioblastoma multiforme, different fractionation schedules and radiation sensitizer were tried with no avail. Studies have shown that therapies performed had not improved survival and had only achieved palliative effects. In our clinics between 1994 and 1998, hypofractionated radiotherapy with high dose fractions (20-30 Gy/10 Gy fx/with 10 day intervals) was applied to 58 glioblastoma multiforme patients with poor performance status. Anti-edematous treatment was initiated concomitantly. Median survival time was 19 weeks. In post treatment clinico-neurological assesment complete or partial response (58.6%; 34/58) was achieved. As a result, the side effects of hypofractionated radiotherapy with high dose fractions in glioblastoma multiforme patients with poor performance status were found to be tolerable, and its effects on quality of life and survival were comparable with other fractionation schedules.
