The Pakistan Brain Tumour Epidemiology Study

Area of Science:

• Neuro-oncology
• Epidemiology
• Public Health

Background:

• Brain tumours represent a significant health concern globally.
• Understanding the epidemiology of brain tumours in specific regions like Pakistan is crucial for targeted interventions.
• Limited data exists on the prevalence and risk factors of brain tumours within Pakistan.

Purpose of the Study:

• To determine the epidemiology of brain tumours in Pakistan.
• To identify potential associated risk factors, including family, medical, and social characteristics.
• To establish national prevalence and incidence rates for brain tumours.

Main Methods:

• A retrospective, cross-sectional, nationwide study was conducted.
• Data was collected for brain tumour cases diagnosed between January 1, 2019, and December 31, 2019.
• All age groups and histopathology types were included to capture comprehensive data.

Main Results:

• A total of 2750 brain tumour cases were recorded, with 69% diagnosed in the public sector.
• Gliomas were the most common type (28.29%), while pineal tumours were least common (0.69%).
• Hypertension (51.89%) and smoking (62.02%) were the most frequent co-morbidity and social behavior, respectively. Median age at diagnosis was 36 for males and 37 for females.

Conclusions:

• The Pakistan Brain Tumour Epidemiology Study (PBTES) and Pakistan Brain Tumour Classification (PBTC) provide a platform for improved cancer care.
• Strengthening cancer care health systems, implementing treatment guidelines, and regular cancer registration are recommended.
• The study highlights the need for continued research and collaborative efforts in neuro-oncology within Pakistan.
