Cancer incidence rates in the Dallas Fort Worth metropolitan area

This report delineates some of the preliminary and selected data from the cancer survey conducted in the Dallas Fort Worth metropolitan area from 1969 through 1971. A total of 17,371 incident resident cases (excluding carcinoma in situ and nonmelanoma skin cases) were identified in the Dallas Fort Worth area, of which 8,886 were men and 8,485 5,642 5,768 tumor results obtained in 88 patients older than 70 yr who underwent spinal anaesthesia for urologic operations are presented. The choice of older patients, at higher risk, allows more conclusive evidence to be drawn. It is concluded that spinal anaesthesia is the elective procedure for patients affected by obstructive lung disease, pulmonary tuberculosis, chronic bronchitis, bronchiectasy, obesity, liver failure and diabetes. Arterial hypertension, severe cardiac or circulatory failure, cerebrovascular atherosclerosis contraindicate this procedure. Good results are reported in 91.5% of the cases, unsatisfactory as for intensity and length of analgesia in 5% and negative in 3.5%.
