the accuracy of clinical diagnostics , as reflected in these two determinations , appeared to improve over this period with respect to some of the diseases studied ( rheumatic heart disease and leukemia ) , while for others it worsened ( pulmonary tuberculosis , peritonitis , carcinoma of the lung , gastric carcinoma , and carcinoma of the liver and extrahepatic biliary tract ) and for a significant number diagnostic accuracy seemed refractory to sustained change ( pulmonary embolism , primary cirrhosis of the liver , gastric/peptic ulcer , and acute coronary thrombosis/myocardial infarction ) .
