Incidence of neuroepithelial Primary Brain Tumors (nPBT) varies, ranging from 7.3 to 11.6 cases/100,000/year across Europe. We present incidence and survival of nPBT in the Emilia-Romagna region (ER), Italy. This study is the largest in Southern Europe. Specialists in neurosurgery, neurology, neuroradiology, oncology, radiotherapy, genetics, and pathology of ER notified all suspected nPBT adult cases residing in ER (4,337,966 inhabitants) observed during 2009. Furthermore, through ICD-9 discharge codes, we identified and reviewed all possible cases. Neuroepithelial PBT diagnosis was based on histological or radiological findings. We included 400 incident nPBT cases, of which 102 (25%) were retrospectively identified. These latter were significantly older. The standardized incidence was 10.5/100,000/year (95% CI 9.4â11.5), higher for men. It was 9.2/100,000/year (95% CI 8.3â10.2) for astrocytic tumors, 0.6/100,000/year (95% CI 0.4â0.9) for oligodendroglial tumors, and 7.1 (95% CI 6.3â8.0) for glioblastoma (GBM). Among GBM patients, median survival was 249Â days if prospectively identified vs. 132Â days when identified through ICD-9 codes (pÂ <Â 0.0001). The incidence of nPBT in the ER region is among the highest in the literature. Older patients were more likely to escape an active surveillance system. This should be considered when comparing incidence rates across studies, giving the increasing number of elderly people in the general population.
