Objective: To identify the surgical incidence and prevalence of schwannoma in our region and quantify the demographic, surgical, neoplastic, and outcome characteristics of the patients diagnosed with schwannoma.
Methods: A retrospective cross-sectional study was conducted from January 1 to December 31, 2019. Enrolled were 32 of the highest volume neurosurgical centres in Pakistan. Patients with a histopathological diagnosis of schwannoma and radiological imaging were included in the study. Medical records were reviewed for data, and SPSS version 25 was used for statistical analysis. Patients were followed up for one year, which was the duration of the study.
Results: From 2750 patients diagnosed with brain tumours, 148 patients had schwannomas. Out of these, 84 (56.8%) patients were male, and 64 (43.2%) patients were female. The mean age of the patients was 39 ± 14 years. The socioeconomic statuses of the enrolled patients were lower in 72 (53.3%) patients, middle in 57 (42.2%) patients, and upper middle to upper in 6 (4.4%) patients. All patients underwent surgery, 14 patients received radiotherapy, and two patients received chemotherapy. In our cohort, 115 (77.7%) patients presented to public sector hospitals, with only 33 (22.3%) patients presenting to private hospitals. At the end of the study period, 60 (40.5%) patients had been lost to follow-up. Of the remaining 88 patients, 75 (85.2%) were alive. The mortality rate on a one-year follow-up was 14.8%.
Conclusion: Schwannoma comprises a larger percentage of the brain tumours in our regions than reported in the literature. The high mortality rate is of particular concern and warrants further investigation to improve patient care and outcomes.

Objective: To ascertain the age and gender differences, treatment, and management of meningiomas across Pakistan.
Methods: Data were collected as part of the PBTES, and patients with a histopathological diagnosis of an intracranial meningioma in 2019 that presented at these centres were included in this cohort study sub-analysis. Thirty-two centres participated in the study. Medical students, residents, and faculty collated data from medical records.
Results: Our data indicate that meningiomas constitute 15.6% of all intracranial tumours in Pakistan and occur more often in females (236, 55%) than in males. The mean age at diagnosis was 43.7 ± 19.9 years. Meningiomas had a slightly higher preponderance in the right hemisphere of the brain at 203 (47.32%) tumours and 267 (62.2%) of the tumours in the frontal and parietal lobes. We found that 174 (61.3%) of all meningiomas diagnosed in Pakistan in 2019 were grade I tumours, which was also the most commonly occurring tumour grade. Adjuvant chemoradiotherapy for meningiomas was rarely observed in Pakistan.
Conclusion: The PBTES reveals a low hospital-based incidence of meningiomas in 2019 when compared to the
incidence in high-income countries but found evidence similar to those of other LMICs. Tumour characteristics, such
as location, grading and surgical procedures, were similar to global literature.

Objective: To quantify the frequency of craniopharyngiomas presenting to tertiary care neurosurgical centres, the demographics and mortality rate, and commonly presenting to neurosurgical practice.
Methods: Our study was a retrospective cross-sectional analysis of patients admitted at 32 neurosurgical centres between January 1, 2019, and December 31, 2019, with brain tumour. Kruskal Wallis analysis was used to determine normality; normally distributed variables were reported as means with standard deviation, while median with interquartile range was used for non-normally distributed variables.
Results: Of 2750 patients with brain tumours, 114 patients presented with craniopharyngioma. The median age at diagnosis was 18 years, with 42 (42.8%) patients below the age of 15, 40 (40.9%) patients aged 15-39, and 16 (16.3%) patients aged 40 and above. There were 70 (61.4%) males and 44 (38.6%) females in our cohort. Gross total resection was performed in 42(36.8%), 45 (39.5%) underwent subtotal resection, 9 (7.9%) underwent CSF diversion only, and 2 (1.8%) had a biopsy. Most of our patients 94(82.5%) presented to public hospitals, with 20 (17.5%) patients presenting to private hospitals (p=0.002). The overall survival at two years was 86.8% in patients with known outcomes, and only 10% of patients died within 30 days of surgery.
Conclusion: Craniopharyngiomas comprised a small portion of all brain tumours in our region. They are more
common in males and in patients from the lower socioeconomic class. These patients mainly presented to public
sector hospitals, and the three highest volume centres were all public sector institutions. The overall survival rate at
two years in our region is lower than in other regions.

Published: December 2022

Objective: To quantify the metastatic brain tumour burden presenting to tertiary care neurosurgical centres, the demographics and mortality rate, and the type of metastatic tumours commonly presenting to neurosurgical practice.
Methods: A cross-section retrospective study was conducted on patients diagnosed with brain tumours from 32 neurosurgical centres across Pakistan between January 1, 2019, to December 31, 2019. At least one neurosurgical resident and one neurosurgical faculty member were recruited from each centre as members of the Pakistan Brain tumour consortium. Mean with standard deviation or median with interquartile range was reported as variables.
Results: Of 2750 patients in this cohort, 77 (2.8%) were diagnosed with metastatic brain tumours. The median age of these patients was 52 (IQR= 43-60) years; 9 (14%) adults were aged 20-39 years, 37 (57%) were aged 40-59, and 19 (29%) were aged 60 and above. There were 62 (82.7%) married patients with 4% unmarried. The median KPS score both pre and post-surgery was 80 (IQR= 60-90, 70-90 respectively), and 43 (55.8%) patients were lost to follow-up. The mortality rate for patients that followed up was 50%, 17 patients were alive, and 17 were deceased at the end of the study period. The 30-day mortality rate amongst our patients was 11.8% (n=4).
Conclusion: The number of patients presenting to neurosurgical care with brain metastases is much lower than the expected incidence of metastatic brain lesions. Multidisciplinary integration and the establishment of a registry to track patients diagnosed with brain tumours is the first step in ensuring better care for these patients.

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

Objective: To investigate waiting times for brain tumour surgery in Pakistan from a nationwide sample and highlight specific affected patient populations.
Methods: A nationwide study was conducted as part of the Pakistan Brain Tumour Epidemiology Study; data from 32 high-volume neurosurgical centres were collected. The national sample included 2,750 patients. Time to surgery was calculated by the difference in dates recorded for radiological diagnosis and the date of the first surgery. This was further stratified according to demographic factors, histopathological diagnosis, type of surgical procedure performed and survival outcomes.
Results: The data of 1,474 patients for time to surgery was available. Patients travelling to public hospitals had significantly longer mean wait times (94.07 (CI: 85.29, 102.84) vs 75.14 (CI: 54.72, 95.56) days, p<0.001). Significant differences were seen between patients of various age groups, as adolescents (116.63 (CI: 65.27, 167.98) days) and young adults (103.34 (CI: 85.96, 120.72) days) had higher waiting times compared to middle-aged (72.44 (CI: 61.26, 83.61) days) and older (48.58 (CI: 31.17, 65.98) days) adults. No difference was seen between the genders. A significantly longer time to surgery was observed for middle- and lower-socioeconomic class patients. Those undergoing gross total resection of the tumour had significantly (p<0.001) longer waiting times for surgery when compared to STR (sub-total resection), biopsy, and CSF-diversion procedures, for all tumour types. Patients diagnosed with meningioma had the most prolonged waiting periods (106 (CI: 76, 95) days). Gliomas had a mean waiting period of 88 (CI: 73, 103) days across the country. Low-grade gliomas had significantly (p=0.031) longer mean waiting times (99.73 (CI: 61.91, 127.36) days) in comparison to high-grade gliomas (70.13 (CI: 43.39, 89.69 ) days). A significant difference was seen between waiting times for patients who survived surgical procedures for a brain tumour on the most recent follow-up and those who had expired (91.87 (CI: 79, 107.74) vs 77.41 (CI: 59.90, 94.91) days, p<0.001).
Conclusion: Prolonged delays to surgery are a significant barrier within low-and-middle-income countries, leading to adverse outcomes for patients. Patients undergoing brain tumour surgery at public hospitals from lower or middle SES and electing for gross resections were more likely to have longer delays.
