The aim of this study was to evaluate the outcome and prognostic factors influencing survival in 106 patients with supratentorial malignant gliomas treated with radiotherapy.
The study group included 84 patients treated by surgery and post-operative radiotherapy and 22 patients treated by postbiopsy irradiation.
Radiotherapy was delivered to the tumour area with a 2 cm margin, the aimed curative dose was 60 Gy in 6-7 weeks.
The 60-month overall survival (Kaplan-Meier) was 20%. Following a univariate analysis, younger age (P<0.001), longer duration of symptoms (P=0.009), good performance status after radiotherapy (P<0.001), other than grade 4 histology (P<0.001) and higher radiation dose (P<0.001) were associated with better overall survival rates.
Multivariate analysis found that age, symptom duration, histology, extent of symptoms and radiation dose were independent prognostic factors influencing survival.
In conclusion, conventional radiotherapy of supratentorial malignant gliomas results in survival that is comparable to results from clinical experiments with different fractionation schedules and radiation with chemotherapy or radiosensitisers.
To improve the results, new approaches are needed, especially for patients with the poorest prognosis after standard treatment.
