Abstract

A series of 120 pathologically verified intraspinal tumors was analyzed for the relative incidence and location of the tumors as well as the distribution of age and sex. These data were compared to series from Taiwan, mainland China, Thailand, Korea, Japan, Iran, India, and countries in the West. The ratio of brain to intraspinal tumors was about 5:1 in Taiwan, higher than those reported in China, Korea, and in the West. The male to female ratio is about six to five. For most tumors, male predominance is noted except for meningioma. The incidence of intraspinal tumors in the order of frequency is nerve sheath cell tumor(NSCT), metastatic tumors, meningioma, glioma, congenital tumors, and vascular tumors. In the East, the incidence of NSCT is about 40%, and meningioma is about 10%. In the West, they are both about 20%. Congenital tumors accounted for only 3.3%. In China, it was about 12% and this is the highest incidence of dysembryoplastic tumors in the world. Glioma has similar incidence (about 10%) in Taiwan, China, Thailand, Japan, and Iran (about 10%), whereas it is about 15% in the West and India. Korea has the highest incidence of glioma, (32.3%). Low incidences of metastatic intraspinal tumors (4.6-5.5%) were noted in Ch...Continue Reading
