Abstract

Abstract : Objectives: High serum level of interleukin 6 (IL-6) is associated with high degree of tumor progression and systemic weakness. Anti–IL-6 therapy possibly improves the deterioration of clinical characteristics in patients with high IL-6 level. However, IL-6–related factors in patients with treatment-naive advanced pancreatic cancer (PC) have not been established. The goal of this study was to identify IL-6–related factors in patients with advanced PC who were scheduled to undergo first-line chemotherapy. Methods: Patients with treatment-naive advanced PC were eligible for inclusion in this study. Patients who did not receive first-line chemotherapy were excluded. Serum IL-6 levels and clinical parameters were prospectively recorded. Analyses were performed to identify risk factors for high IL-6 levels. Results: Eighty patients were analyzed. IL-6–related factors were advanced age ( P < 0.01), the presence of liver metastasis ( P < 0.01), the large volume of liver metastasis ( P < 0.01), severe fatigue ( P = 0.02), high carcinoembryonic antigen levels ( P = 0.02), anemia ( P < 0.01), and high C-reactive protein levels ( P = 0.02) in multivariate analyses. Decreased skeletal muscle mass tended to be associated with high IL-6 levels. Conclusions: High serum IL-6 was related to advanced age, the presence of hepatic metastasis, large tumor burden in liver, severe fatigue, high carcinoembryonic antigen, high C-reactive protein, and anemia in patients with treatment-naive advanced PC.
