Association of plasma adiponectin and leptin levels with the development and progression of ovarian cancer.

Abstract

ObjectiveDecreased adiponectin and increased leptin plasma concentrations are believed to be associated with the occurrence and progression of cancers such as endometrial cancer and breast cancer. The aim of this study was to explore the association of plasma adiponectin and leptin levels with the development and progression of ovarian cancer.MethodsFor patients with ovarian cancer and the control group, adiponectin and leptin levels were measured; anthropometric data were obtained during a chart review. Statistical comparisons between groups were analyzed using the Student's t-test; correlations were confirmed using the Pearson correlation.ResultsThe mean adiponectin and leptin concentrations in patients with ovarian cancer were lower than those of the control group (8.25 vs. 11.44 µg/mL, respectively; P=0.026) (7.09 vs. 15.4 ng/mL, respectively; P=0.001). However, there was no significant difference in adiponectin and leptin levels between early-stage (I/II) and advanced-stage (III/IV) disease (P=0.078).ConclusionCompared with other gynecological cancers, the level of adiponectin and leptin were decreased in ovarian cancer that may have some diagnostic value; additional study to elucidate the function of these two hormones in the development of ovarian carcinogenesis is necessitated.
