Utility of gene promoter methylation in prediction of response to platinum-based chemotherapy in epithelial ovarian cancer (EOC).

Abstract:

:The aim was to determine whether promoter methylation of BRCA1, MGMT, MLH1, RASSF1A, and p16 genes could predict response to platinum-based chemotherapy. Thirty-five subjects with epithelial ovarian cancer (EOC) treated by platinum-based chemotherapy were recruited. Methylation-specific polymerase chain reaction was carried out and the methylation index (MI) was also derived. Response to platinum-based chemotherapy was documented clinically, radiologically, and by serial CA125 levels. Methylated BRCA1 (p = .037) and a higher MI (p = .045) were associated with primary chemosensitivity. A better outcome was predicted by a higher MI (p = .032). In EOC, BRCA1 gene promoter methylation is useful in the prediction of response to chemotherapy.

  • Anemia in cancer.

    abstract::In summary, anemia developing in a patient with cancer can be due to several different factors. A relative failure of erythropoiesis, in conjunction with a modestly shortened erythrocyte survival, is the most likely explanation for the anemia and can occur in patients with or without bone marrow invasion. Several theo...
