Epidemiology of Primary Brain Tumors in the Province of Catania during the 2003-2016 Period.

Abstract : Introduction: Primary brain tumors (PBTs) account for approximately 2% of all cancers and are associated with significant morbidity and mortality. However, only few epidemiological studies focus on PBTs in Italy. The aim of this study was to evaluate incidence, temporal trend, and survival rate of all PBTs in the province of Catania during the study period. Methods: All patients diagnosed with PBTs in the province of Catania during the 2003-2016 were identified through the local cancer registry. All cases were classified by histology according to 2007 WHO classification of central nervous system tumors, using the International Classification of Diseases for Oncology, 3rd edition codes. The incidence rate (IR) was calculated for all PBTs and by gender, histology, age-groups, and behavior. Trend analysis was performed using a piecewise log-linear model. Results: A total of 3,819 cases were identified with a female/male ratio of 1.45. The IR for all PBTs was 25.3/100,000 person-years (95% confidence interval 24.5-26.1). Most PBTs were nonmalignant (59.5%, IR = 15.0) with a female predominance. Conversely, malignant tumors (32.4%, IR = 8.2) were more common among men, with a female/male ratio of 0.9. The most frequently reported histology was meningioma (39.0%, IR = 9.8), followed by glioblastoma (11.6%, IR = 2.9). A peak of incidence was found in the 75-84 years age-group, with an IR of 77.6/100,000 person-years. Overall, no increase in incidence was observed along the study period. Conclusions: The IR of PBTs in the province of Catania is close to incidence reported worldwide. Further studies on risk factors are necessary.
