Abstract:
Objective Investigate the frequency of loss of heterozygosity (LOH) at chromosome arm the short arm chromosome 3p14,25 in the serum DNA from ovarian cancer and its clinical application Methods Thirty eight ovarian cancer serum samples with 18 corresponding tumor tissues and 8 benign ovarian tumors were obtained,and DNA samples extracted from serum and tissue were examined for 3p14,25 LOH by using of polymerase chain reaction with four polymorphic microsatellite markers (D3S1029, D3S1228, D3S1300, D3S1481) Results Matched serum and tissue DNAs from 18 ovarian cancer patients showed significant concordance of 3p14,25 LOH ( P
