However, the relationship between serum albumin levels and mortality in patients with cancer cachexia remains unclear. We aimed to examine the association of albumin and total protein with 1-year mortality in patients with cancer cachexia.Patients and Methods: We conducted a nested case–control study using data from a multicenter cancer clinical survey from 2013 to 2018. In total, 266 patients with cancer cachexia who survived for < 1 year and 266 patients who survived for ≥ 1 year were included in this study. The participants were matched by age, sex, tumor type, tumor stage, and hospital site. The crude and adjusted risks of 1-year survival were estimated using odds ratios (ORs) and 95% confidence intervals (95% CIs) using logistic regression, with or without adjustment for covariates.Results: Logistic regression analysis revealed a significantly negative linear association between albumin level and 1-year mortality in patients with cancer cachexia (p < 0.001). An L-shaped relationship existed between total protein and 1-year mortality, with a turning point at 70.4 g/L. When albumin was divided into quartiles, Q3 (OR: 0.40; 95% CI: 0.24, 0.68; p < 0.001) and Q4 (OR: 0.33; 95% CI: 0.19, 0.55; p < 0.001) were associated with higher 1-year survival than Q1 among patients with cancer cachexia. When total protein was divided into quartiles, Q2 (OR: 0.38; 95% CI: 0.23, 0.64; p < 0.001), Q3 (OR: 0.57; 95% CI: 0.33, 0.96; p = 0.035), and Q4 (OR: 0.43; 95% CI: 0.25, 0.72; p = 0.002) were associated with higher 1-year survival than Q1 among patients with cancer cachexia.Conclusion: Serum albumin and total protein may predict 1-year survival. Future clinical studies should lead to a more comprehensive understanding of the effects of serum protein levels in patients with cancer cachexia.Keywords: nutrition, survival, death, cachectic patients
