Intracranial neoplasms: A ten year experience

ABSTRACT

The epidemiologic features of 652 histologically confirmed intracranial tumors were reviewed. 600 were primary tumors and 52 were metastatic. 17.4% of all tumors were gliomas and 23.2% were meningiomas. 73% of adult tumors were supratentorial, most commonly meningiomas, while 10% of pediatric tumors (age14) were infratentorial, predominantly medulloblastomas. There was an equal distribution of the tumors in the first decades of life. The medulloblastomas and astrocytoma I-II, peaked in early childhood whereas meningiomas, neurilemmomas and metastatic tumors increased in frequency with advancing age. The overall risk for intracranial tumors was the same for both sexes. However, women had greater susceptibility for meningiomas, pituitary adenomas and merilemmomas. The features of intracranial tumors in Filipinos mirrored those seen in Blacks and other Asians, and differed from most Western profiles. It is possible that racial difference play a role in the development of intracranial tumors.
