Epid-32. Survival of Intracranial Tumor in Cipto Mangunkusumo General Hospital

Abstract

INTRODUCTION Intracranial tumor is a debilitating health burden that cause sever disability. The incidence rate for intracranial tumor is 4.63 per 100,000 populations. Through the development of diagnostic and therapeutic modalities, the survival of intracranial tumor improved although modest. There were several factors such as demographic, clinical, and histopathological affect intracranial tumor survival. However, there were no study about intracranial tumors and factors affecting it survival in Indonesia. This study provides insight of intracranial tumor patients and factor affecting 1-year survival in Cipto Mangunkusumo General Hospital from 2014–2016. METHODS The design of this study is retrospective cohort. The subjects were followed-up 1 year after diagnosis. The data retrieved from Dept. of Neurosurgery and Dept. of Neurology Cipto Mangunkusumo General Hospital neuro-oncology registry. Subjects with intracranial tumors underwent surgery/biopsy were included in this study. The factors analyzed in this study were demography, clinical characteristics, histopathology, and treatment types. Analysis of survival were done with Kaplan-Meier curve and cox regression. RESULTS There were 317 subjects in this study. Overall 1-year survival of intracranial tumors were 75.4%. There was increased risk of death (HR 1.88; CI95% 1.2–2.94; p = 0.005) in subjects >46 years old. There was no different of risk of death (HR 0.66; CI95% 0.92–1.03; p = 0.067) between men and women. There was no different of risk of death (HR 1.39; CI95% 0.72–2.70; p = 0.333) between supratentorial and infratentorial tumor. There was difference of survival among histopathology (p < 0.001) and therapeutic approaches (p < 0.001). DISCUSSION This is the first study in Indonesia that analyze survival of intracranial tumor. Several factors such as age, histopathology, and therapeutic approaches were found to affect 1-year survival of intracranial tumor. To get a representative insight of intracranial tumor in Indonesia, a larger cohort study should be conducted.
