Association between Postoperative Detection of Circulating Tumor Cells and Recurrence in Patients with Prostate Cancer

Abstract

Circulating tumor cells in the blood were frequently detected in patients with undetectable prostate specific antigen levels after radical prostatectomy for localized prostate cancer. Furthermore, circulating tumor cell detection was associated with an increased risk of biochemical recurrence, suggesting that circulating tumor cell detection precedes prostate specific antigen rise after surgery in cases of prostate cancer recurrence. Large-scale validation is needed in the future.
