The Serum Leucine Aminopeptidase Test

CARCINOMABRrnsH 1787 in the uterine preparation is indeed present in the serum of 95% of patients with cancer, as Makari claims. SummaryA preliminary attempt to use the Schultz-Dale technique in the diagnosis of cancer has been successful in 23 cases of carcinoma, and unsuccessful in 26.The claims of Makari and of Burrows that the test has an accuracy of over 95% have not been substan- tiated.On the other hand, the results can be taken to confirm the immunological basis of the method.We are grateful to the consulting physicians and surgeons of the Royal Adelaide Hospital and of the Queen Elizabeth Hospital, Adelaide, who suggested that we should test serum from their cases; to Professor R. F.
