Blood Test May Help Signal Tumor’s Remission, Return in Throat Cancer Patients
A blood test that detects proteins commonly released by a growing tumor could one day become a useful tool for monitoring the effectiveness of chemotherapy and radiation treatment in people with advanced throat cancer, according to a study published in the June 1, 2007, issue of Clinical Cancer Research. Scientists in the NIDCD, National Cancer Institute (NCI), and University of Michigan found that throat cancer patients who showed a decline in several cancer-related proteins following chemotherapy and radiation treatment were more likely to remain in remission, while those who experienced a large rise over time in those proteins frequently exhibited a return of throat cancer. The findings could help doctors detect the recurrence of throat cancer early on, when there is still time to pursue a second line of treatment, such as surgery or drug therapy.
