These investigators also found that the overall performance of cfDNA screening was superior to that of standard screening, although outcomes were incomplete for continuing pregnancies at the proper time of publication.15 Although these findings are encouraging, the cited studies examined narrowly defined populations and screening algorithms that do not represent the more technical and variable approaches currently found in america. Recently, there were multiple appeals for proof concerning the performance characteristics of cfDNA tests and its clinical usefulness in the overall obstetric population.16,17 Here, we describe the outcomes of the Comparison of Aneuploidy Risk Evaluations study, a prospective, blinded, multicenter observational research comparing the outcomes of non-invasive prenatal cfDNA screening for fetal autosomal aneuploidy with the outcomes of conventional screening for trisomy 21 and trisomy 18 in an over-all obstetrical population, with outcomes included.Randomization and Treatments Randomization was performed by an interactive phone or Web-based program centrally, with stratification according to GCIG group, FIGO stage and residual disease and paclitaxel , given every 3 weeks for 6 cycles , or even to the same regimen as well as bevacizumab , given concurrently every 3 weeks for 5 or 6 cycles and continuing for 12 extra cycles or until disease progression . Bevacizumab was omitted at cycle 1 in order to avoid delayed wound healing if chemotherapy was began within four weeks of surgery. Cycles of bevacizumab that were omitted for any reason were not replaced. Assessments Assessments were performed simultaneously points in the two treatment groupings. Clinical assessments and cancers antigen 125 measurements were performed before every cycle of chemotherapy, every 6 weeks in season 1 then, every 3 months during years 2 and 3, every six months during years 4 and 5, and then yearly.
