<![CDATA[Metastatic brain tumors, surpassing primary brain tumors in prevalence by tenfold, are the most common brain neoplasms, emphasizing the role of early diagnosis in improving the patient's quality of life. This study aimed to identify the characteristics of brain tumor metastases at Cipto Mangunkusumo National Referral Hospital. With consecutive sampling, a cross-sectional design study using secondary brain tumor data was conducted at dr. Cipto Mangunkusumo National Referral Hospital from January 2016 to December 2020. Characteristics data were presented in percentages, and bivariate analysis was conducted using Chi-square or Fisher's test. Among 222 subjects (mean age 50.9 ± 10.4 years, 60.8% women), metastases were predominantly supratentorial (50.6%), multiple (65.8%), and associated with mass effects (51.4%), particularly midline shift (69.6%). Primary tumors were predominantly lung (36.5%) , breast (34.2%), and 55.9% experienced metastases in other organs. Brain metastases manifested metachronously in 67.6% of cases, with primary breast tumors showing a higher propensity for metatentorial and infratentorial metastases, while primary lung tumors showed a synchronous onset. The study highlighted associations between mass effects, loss of consciousness -, and poor performance in subjects. Primary lung and breast tumors exhibited the highest incidence of brain metastases.]]>
