Abstract

Background: The pro-inflammatory cytokine interleukin-6 (IL-6) plays a role in cancer development and progression, but research into the predictive value of IL-6 on postoperative outcome in soft tissue sarcoma (STS) is scarce. The purpose of this study is to investigate the predictive value of serum IL-6 level for the achievement of assumed (post)operative outcome after STS surgery, the so-called textbook outcome. Methods: Preoperative IL-6 serum levels were collected in all patients with a STS at first presentation between February 2020 and November 2021. Textbook outcome was defined as a R0 resection, no complications, no blood transfusions, no reoperation within the postoperative period, no prolonged hospital stay, no hospital readmission within 90-days, and no mortality within 90-days. Factors associated with textbook outcome were determined by multivariable analysis. Results: Among 118 patients with primary, non-metastatic STS, 35.6% achieved a textbook outcome. Univariate analysis showed that smaller tumor size (p = 0.026), lower tumor grade (p = 0.006), normal hemoglobin (Hb, p = 0.044), normal white blood cell (WBC) count (p = 0.018), normal C-reactive protein (CRP) serum level (p = 0.002) and normal IL-6 serum level (p = 1.5 × 10−5) were associated with achieving textbook outcome after surgery. Multivariable analysis showed that elevated IL-6 serum level (p = 0.012) was significantly associated with not achieving a textbook outcome. Conclusions: Increased IL-6 serum level is predictive for not achieving a textbook outcome after surgery for primary, non-metastatic STS.
