Abstract [en]

The annual incidence rate of high grade malignant glioma (WHO grade III-IV) in Sweden is approximately 400 patients. The objective for the Swedish National CNS-tumor Group is to lay a foundation for research efforts and facilitate implementation and assessment of therapeutic strategies and health care for this patient group. In the analyses the diagnoses of high grade malignant gliomas are compared for the years 1999-2003, 2004-2006 and 2007-2009 for the Northern Region, the Uppsala Region and the South-east Region of Sweden, a population of 1844 patients. Survival was estimated from Kaplan-Meier survival curves, and a log-rank test was performed to assess whether the survival curves differed. The crude hazard ratio between years of diagnosis was estimated from a Cox regression model. Median survival for all patients 2004-2006 was 10.0 months (95 % confidence interval (CI) 8.9-10.9) compared to 8.1 months 1999-2003 (95 % CI 7.3-8.8). For patients 60-69 years of age almost a doubling of the survival rate has occurred during the last decade. Medan survival has increased from 5.8 months (95 % CI 5.1-7.5) 1999-2003 to 8.5 months (95 % CI 7.0-10.3) for 2004-2006 and to 10.5 months (95 % CI 9.0-12.6) for 2007-2009. Concomitant radiochemotherapy, but also the development of neurosurgical and radiotheraputic techniques and a more active therapeutic attitude, including the older patient groups, have probably contributed to the improved survival rate. A national population based registry, with a close to 100% registration compliance for important diagnostic and outcome parameters is probably an efficient instrument for evaluation of quality measures and implementation of new therapeutic strategies.
