Abstract

We have studied 1927 cases of primary tumor patients, who were admitted, managed and registered at Cancer Center of Maryknoll Hospital from Nov. 1985 to Jun. 1988. Of these, 50 cases were metastasized to central nervous systems, and the cases of brain metastases were 31 cases. This report presents an analysis of 31 cases of metastatic brain tumors. The results are as followings: 1) The sexes were represented with 20 males and 11 females. In 20 cases(65%), the metastases occurred between the 6th decade and 7th decade. 2) The most frequent anatomical site of brain metastases was brain parenchyme(67.7%). 3) The most frequent site of primary malignancy was lung(45.2%), and the next order was choriocarcinoma of the uterus. 4) The clinical symptoms and signs of metastatic brain tumors were headache(87%), nausea, vomiting(35.5%) orderly. 5) In C-T scan findings, the metastatic brain tumors presented hyperdense area at 50% of cases before contrast enhancement, and were enhanced nearly almost of cases. 6) In cases which could be treated surgical procedure, radiation and chemotherapy seemed to improve the prognosis.
