fL New Serum Developed
To Test For Cancer
A simple and inexpensive method of blood serum testing for the diagnosis of cancer has been developed by doctors in the Veterans Administration Hospital at bos' Angeles, Calif.
Using a synthetic substance, which .they substituted for an antigen obtained from human cancerous liver tissue, the doctors obtained almost identical results when the material came into contact with the blood serum of a person afflicted with cancer. The tests were more than 98 per cent correct in confirming positive cancer diagnosis.
Tests using the synthetic material on more than 900 patients were-described in papers read before the annual meeting of the American Association for Cancer research in Cleveland, Ohio, by Dr. Claude S. Mummtf, chief of the eye, ear, nose and thrpfct department, and Dr.' F. X.»Byron, chief-of thoracic surgery, in the Los Angeles VA Hospital. The work described was done in conjunction with a group of medical scientists from the University of California at Los Angeles, working in the VA Hospital the past four years.
Known in medical circles as the “sero-fioeeuiation reaction,” the blood serum method of testing is expected to lead to earlier* discovery of cancerous lesions in the lungs and other chest areas.
In his paper evaluating the blood serum test, Dr. Byron said that the nature of the bronchogenic carcinoma (cancer of the chest or longs) made diagnosis “potentially difficult.’’ He pointed out that such cancer often simulates other types of pulmonary lesions and often leads to late . diagnosis even when the patient presents himself to a physician early in the course of the disease.
