Bone scintigraphy in patients with breast cancer, pulmonary cancer, uterine cervix cancer, and prostatic cancer. Statistical study of spinal accumulation cases.
This is a review of bone scintigraphy performed in patients with breast cancer, pulmonary cancer, uterine cervix cancer, and prostatic cancer from 1980 to 1985. The incidence of accumulation in the spine was 25.0% in breast cancer, 29.5% in lung cancer, 24.3% in cervical cancer, and 47.0% in prostatic cancer. The predominant location of the accumulation was the lumbar vertebra (68.9%), followed by the thoracic vertebra (45.0%), sacral vertebra (37.5%), and cervical vertebra (23.6%). The survivability after spinal accumulation was determined by the Kaplan-Meyer survival curve. The 1-year survival rate of breast cancer, pulmonary cancer, cervical cancer, and prostatic cancer was 88%, 19%, 74%, and 90%, respectively, the record of pulmonary cancer being significantly lower. Hence, in the treatment of patients with metastatic spinal tumors, the therapeutic method should be selected according to the underlying disease.
