Abstract

Introduction:

Cancer cachexia is one of the most frequent effects of malignancy, is often associated with poor prognosis, and may account for up to 20% of cancer deaths. The aim of our study was to evaluate the relationship of cancer cachexia and serum levels of resistin and leptin in patients with advanced non–small cell lung cancer.

Methods:

A total of 67 chemotherapy-naïve patients with advanced-stage non–small cell cancer and a control group containing 20 healthy individuals without a known chronic disease were enrolled in this study. All individuals in the control group were age and sex matched. Demographic, anthropometric, laboratory data and serum levels of adipokines were measured for 2 groups. Progression-free survival and overall survival were estimated using the Kaplan-Meier method. Survival among various factors was calculated using the log-rank test.

Results:

Patients presented significantly higher serum resistin (P = .0001) and lower serum leptin levels (P = .025) than the control group. Lower serum levels of leptin were correlated with overall survival (P = .011).

Conclusions:

Serum leptin and resistin levels play key role as proinflammatory cytokines in lung cancer and cancer cachexia; however, their use as diagnostic or prognostic markers is not possible yet, and further large-scale studies are required to confirm our findings.
