Gender disparities in brain tumours: A Pakistan brain tumour epidemiology study analysis

To explore the differences in demographic, surgical, and prognostic characteristics between the two genders in patients with brain tumours in Pakistan.

This study was a retrospective cross-sectional analysis of patients with a histopathological brain tumour diagnosis across 32 high-volume hospitals in Pakistan. The study period was from January 1, 2019, to December 31, 2019. There were no restrictions on inclusion apart from time..

From 2750 patients enrolled in the study, 1605 (58.4%) were male, and 1142 (41.6%) were female . The median age amongst males was 36 (24-49), while the median age amongst females was 37 (24-48). The ratio of married to unmarried patients was 2.7:1 for females and 1.3:1 for males. Surgical treatment was carried out for 1430 (58.1%) males and 1013 (41.9%) females. The median time to surgery was 25 (4-107) days for males and 31 (5-98) days for females. The greatest disparity in tumour malignancy was in grade IV gliomas.

Males generally have a higher incidence of brain tumours in our experience, apart from meningiomas, which favour females. The mortality rate and glioblastoma incidence rate are both higher amongst males. However, post-treatment cure is also witnessed. Sociocultural norms play a prominent role in accessing healthcare. Women are generally at a disadvantage compared to their male counterparts, which may impact reporting of brain tumour cases and treatment outcomes.
