Circulating tumor cells as a new and additional approach to follow-up patients with serous low-grade ovarian adenocarcinoma – a case report and review of the literature

摘要

BackgroundCurrent methods for follow-up of Ovarian Cancer (OC) are widespread, especially with CA125, which, however, is not a perfect biomarker and thus further investigation for new methods of evaluation are warranted. The feasibility of Circulating Tumor Cells (CTCs) in advanced OC was investigated in this case report. Case presentationA 19-year-old woman with advanced low-grade serous papillary adenocarcinoma and relapsed disease did not have a CA125 correspondent with disease relapse. CTCs were evaluated, compared with CA125 and with image exams. Relapses were not correspondent to elevations of CA125. CTCs demonstrated usefulness, being proportional to major disease relapse, especially in the peritoneum. CTCs may be used as a complementary diagnosis tool when marginal/small increases in CA-125 levels are observed. ConclusionsIn OC, CTCs can be an important tool to predict recurrence, response to treatment and improve the quality of decision-making, in order to offer the best treatment to a determined group of patients.
