The effect of radiation therapy, either alone or combined with surgery or chemotherapy is accepted well in the treatment of metastatic carcinoma, multiple myeloma, reticulum cell sarcoma and Ewing's sarcoma. But its effect on osteosarcoma and chondrosarcoma is less clear. The authors reviewed 90 patients treated with radiation therapy, 62 cases with primary bone tumor and 28 cases with multiple myeloma, from 1969 to 1988. There were 20 Ewing's sarcoma, 12 osteosarcoma, 12 chondrosarcoma, 9 Histiocytosis-X and 3 reticulum cell sarcoma among 62 primary bone tumors. And 40 patients with more than three months follow-up were analyzed for the primary response of tumor three months after radiation therapy and the long term effect of the radiation therapy. When the radiation therapy was done alone, the primary response was poor in osteogenic sarcoma, chondrosarcoma, Ewing's sarcoma and reticulum cell sarcoma. But with the multimodal therapy, the primary response was rslatively good in reticulum cell sarcoma and chondrosarcoma. In 15 patients, more than one year follow-up was done. The status of these patients at the last follow-up was poor in all cases trearted with radiation therapy alone than the multimodal therapy except Histiocytosis-X. In multiple myeloma, the effect of radiation therapy for the relief of pain was analyzed. There were complete relief of pain in 14.3%, partial relief in 71.4% and no relief in 10.7%.

Cigarette smoke is a complex mixture of 4,000 chemical compounds, including 43 known carcinogens. It is well known that smoke acts as the initiator and promoter in the process of carcinogenesis, and the risk of cancer is directly proportional to the amount and duration of smoking. Tobacco is the cause of 30% of all cancer deaths and one of the major risk factors for coronary heart disease, along with high blood pressure and hyperlipidemia. Cigarette smoking is estimated to be responsible for more than 20% of all coronary heart disease deaths in men over 86 years of age and for approximately 45% of such deaths in men aged less than 65 years. About 80% of mortality from chronic obstructive lung disease is attributable to cigarette smoking, and the age-adjusted death rate for COPD is 10-times higher in current smokers than in nonsmokers. Peptic ulcer disease, osteoporosis, skin wrinkling, and retarded fetal growth are all associated with cigarette smoking. Through passive smoking, 69% of individuals develop eye irritation, 29% have nasal symptoms, 32% have headaches, and 25% develop a cough. The infant admission rate increases with mother’s smoking amount, and the relative risk of lung cancer is 1.8 in smoker’s spouse. Tobacco is the single, chief, avoidable cause of death in our society, and the most important public issue of our time.
