    Abstract

    Purpose: The purpose of this study was to evaluate the prognostic role of interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α) in the survival of patients with advanced cancer. Methods: In this prospective cohort study between three hospice and palliative care centres in South Korea, we followed 98 advanced cancer patients until death or the end of the study. Approximately 60 % of the patients had poor functional status (Eastern Cooperative Oncology Group score ≥3). We investigated the symptoms of cancer cachexia anorexia syndrome, possible cytokine-related confounders such as infection and medication records. Influence from clinical variables was adjusted using the Cox proportional hazard model. Results: The median survival time was 27 days. On multivariate analysis, elevated IL-6 (hazard ratio, 2.139; p = 0.003) was found to be an independent significant prognostic factor. TNF-α was not a significant factor. Poor performance status and male gender were also independently related to shortened survival. Conclusions: IL-6 level can be a useful indicator of survival time of patients with advanced cancer at the very end of life. In contrast, the prognostic role of TNF-α requires further study.
