A retrospective review of 102 patients with metastatic bone tumor seen at Hanyang University Hospital from 1986 to 1990 was performed. We analyzed the cases in the aspects of primary lesions, age and sex distributions, locations and number of
metastatic
foci, compared with those in the previous reports in Korea.
1. 54.9% of the patients were male and 45.1% were female. The incidence of the metastatic bone tumors in female compared with the previous incidence before 1980's years was relatively increased. The peak age was in the 6th decade. The incidence
younger
than 50 years was decreased, and the incidence older than the 7th decade was relatively increased.
2. The main primary cancers were lung(40.2%), liver(11.8%), breast(10.8%), unknown(8.8%), and uterine cervix(6.9%) etc. In cases of lung cancer, the frequent histologic types were adenocarcinoma, squamous cell carcinoma, and small cell
carcinoma.
3. The vertebrae (56.9%), ribs(40.2%), femur(17.6%), pelvis(15.7%) were relatively frequent sites of metastasis which involved multiple metastasis.
4. Single metastasis(62.4%), was more frequent than multiple metastasis(37.6%).
5. In the primary cancers, the incidence in hepatoma of male was increasing, the incidence in lung cancer of female was relatively increasing, but the incidence in stomach cancer was decreasing.
