A diagnostic test for cancer that could revolutionize screening for the deadly disease has been developed by researchers at Johns Hopkins Medical Institutions. The new test, reported in today's issue of Proceedings of the National Academy of Science, identifies replication errors in DNA that occur frequently in cancer. The errors, known as clonal markers, are used as a fingerprint for cancer.

Amid signs that the world's first SARS outbreak may have run its course, a leading World Health Organization official warned Thursday that detecting any recurrence of the pneumonia-like disease next winter will pose an entirely new set of medical challenges. Those stricken with severe acute respiratory syndrome initially carry an extremely low level of the virus, making an immediate diagnosis all but impossible, said the WHO's senior communicable diseases specialist, David Heymann.

Ovarian cancer is uncommonly deadly. Tumors aren't usually detected until the disease has spread beyond the ovaries, at which point only a third of patients survive more than five years. A promising blood test could change this bleak picture, enabling doctors to identify ovarian cancer at its earliest, most treatable stage. "This has the potential of being an important advance," says Dr. Philip DiSaia, director of gynecological oncology at the UC Irvine School of Medicine.

Abbott Laboratories Inc., the nation's largest maker of medical diagnostic tests, agreed Tuesday to pay a $100-million fine and stop selling more than 100 products until it corrects repeated violations of federal quality rules. The company's violations date to 1993, said the Food and Drug Administration, which sought a consent decree to settle the issue because Abbott did not correct the problems despite six years of government inspections and warnings.
