We are pleased to share this special supplement on the Pakistan Brain Tumour Epidemiology Study (PBTES) with our readers. A total of 16 articles were accepted for publication, ranging from overarching analyses of neuro-oncology epidemiology, practices, and outcomes to the way forward in improving brain tumour patient outcomes.

As the editorial board, we would like to extend our deepest gratitude to the Pakistan Brain Tumour Consortium members, whose contributions in laying the foundations of this national study have been instrumental. We are grateful for the privilege of benefiting from every centre’s experiences and hope to lay the foundation for

Epidemiological studies have significantly helped determine the burden, types, and geographical distribution of brain tumours in HICs (high-income countries).
