Key clinical point: Improved pretreatment values of the prognostic nutritional index (PNI) , an indicator of nutritional immune status, was linked to better long-term survival outcomes in patients with breast cancer (BC).
Major finding: Although low pretreatment PNI did not have any effect on 1-year overall survival (OS) outcomes (odds ratio [OR] 1.55; P = .353), it was significantly associated with worse 3-year (OR 2.34; P < .001), 5-year (OR 3.18; P < .001), 8-year (OR 2.74; P = .001), and 10-year (OR 2.58; P = .021) OS.
Study details: Findings are from a meta-analysis of eight studies including 2322 patients with BC.
Disclosures: This study was funded by the National Natural Science Foundation of China and other sources. The authors declared no conflicts of interest.
