Chung, Lee, Baek, Lee, Ahn, and Yoon: Clinical Analysis of Metastatic Bone Tumor

Abstract

Among the metastatic bone tumor patients who had been treated with operation, radiation therapy, chemotherapy or radioisotope iodine therapy at Korea Cancer Center Hospital from 1980 to 1989, we adopted 190 cases which could be traced. We analyzed the cases in the aspects of location, age and sex distribution, primary lesion, and number of metastatic foci. 1. The main primary cancers were breast(27.4%), lung(18.4%), thyroid(6.8%), liver(6.8%), and uterine cervix(5.7%), but there was also metastasis of unknown origin(11.1%) 2. Just over 56.3 percents of the patients were female and 43.7 were male. The peak age incidence was in the 6th decade. 3. The vertebrae(36.1%), pelvis(16.9%), and femur(14.8%) were relatively frequent sites of metastasis and the rib(13.8%), humerus(6.3%), skull(6.1%), and scapula(2.1%) were followed in order of frequency. The lumbar spine and ilium were the most frequent site of metastasis in spine and pelvis respectively. 4. Multiple metastasis(66.8%) was more frequent than single metastasis. 5. In case of breast cancer, the peak age incidence was in the 5th and 6th decade, and the spine, rib, pelvis, femur, and skull are the frequent sites of metastasis. 6. In case of lung cancer, the peak incidence was in the 6th decade. The frequent sites were spine, pelvis, and femur. 7. In case of metastasis of unknown origin(MUD), the age distribution was broad from 3rd decade to 8th decade, and the peak age incidence was in the 7th decade. The frequent sites of metastasis were spine, pelvis, femur, rib, tibia in order of frequency. The main pathologic type of MUO was adenocarcinoma(47.6%).
