Abstract Purpose  Inflammation-based markers predict long-term outcomes of various malignancies. We investigated the relationship between these markers and the long-term survival in obstructive colorectal cancer (OCRC) patients with self-expandable metallic colonic stents (SEMSs) who subsequently received curative surgery. Methods  We retrospectively analyzed 72 consecutive pathological stage II and III OCRC patients between 2013 and 2019. The prognostic significance of the prognostic nutritional index (PNI), neutrophil–lymphocyte ratio (NLR), lymphocyte– monocyte ratio (LMR), and platelet–lymphocyte ratio (PLR) was evaluated. Results  The overall survival (OS), cancer-specific survival, and disease-free survival (DFS) were significantly shorter in the PNI
