Introduction: Systemic inflammatory and nutritional markers are associated with the prognosis of various cancers. However, their association with sinonasal squamous cell carcinoma (SNSCC) prognosis remains unclear. This study aimed to identify systemic inflammatory and nutritional markers associated with the postoperative prognosis of patients with SNSCC and to clarify the clinical value of these markers.
Materials and methods: Data from 129 patients with SNSCC were included. The optimal prognostic systemic inflammatory and nutritional markers were identified using the area under the curve. The prognostic value was evaluated using COX regression and subgroup analyses; a nomogram was built based on these data.
Results: The advanced lung cancer inflammation index (ALI) and systemic immune-inflammatory index (SII) had higher prognostic values than the other indices; their cut-off values were 27.80 and 791.35, respectively. The nomogram included tumor stage, ALI, and tumor primary site; the calibration and decision curves indicated that the model had good clinical value.
Conclusion: The ALI and SII have potential prognostic value for postoperative patients with SNSCC. The nomogram constructed in this study could be used as a tool to assist physicians in making clinical decisions.
