Post-chemotherapy PCR aids in prognosis.

Post-chemotherapy PCR aids in prognosis

Since scientists developed the gene-amplifying procedure called polymerase chain reaction (PCR) just three years ago, they have applied it to a host of experiments testing for the presence of tiny amounts of DNA (SN: 4/23/88, p.262). Now researchers in London, England, have found PCR useful for detecting remnants of cells containing cancer-causing gene rearrangements in lymphoma patients following chemotherapy.

PCR performed on blood or tissue samples should help physicians tell whether a cancer has spread and may prove useful for monitoring treatment effectiveness, say St. Mary's Hospital Medical School researcher D. Cunningham and his colleagues in the April 1 LANCET.
