Pretreatment Hemoglobin Level Is an Independent Prognostic Factor in Patients with Lung Adenocarcinoma

Figure 1

Cumulative survival proportion of patients with LA according to their pretreatment hemoglobin levels. Normal pretreatment hemoglobin (NPHb): men 120–160 g/l, women 110–150 g/l; low pretreatment hemoglobin (LPHb): men < 120 g/l and women ≤ 110 g/l). (a) Overall survival (OS) of NPHb and LPHb patients with LA (log-rank test, χ² = 8.28, and ). (b) LPHb patients had a poorer OS than NPHb patients in the no-lung lobectomy group (log-rank test, χ² = 7.69, ) but not among the lung lobectomy group (log-rank test, χ² = 0.13, ). (c) The LPHb group had a poorer OS than NPHb patients in the no-chemotherapy group (log-rank test, χ² = 12.00, and ) but not among the chemotherapy group (log-rank test, χ² = 0.63, and ). (d) LPHb patients had a poorer OS than NPHb patients among alcohol drinkers (log-rank test, χ² = 12.14, and ), but not among alcohol non-drinkers (log-rank test, χ² = 3.22, and ).
