Univariate analysis revealed that the factors impacting the 30-day mortality were serum albumin level (p < 0.001), hemoglobin level (p = 0.033), TNM stage (p = 0.004), the ECOG-PS score (p < 0.001), hypocalcemia (p = 0.006), renal insufficiency (p = 0.035), and the efficacy of sodium supplementation (p = 0.006) (Table 1). The gene discussed is ALB; the disease is Hypocalcemia.
