Total iron-binding capacity is a novel prognostic marker after curative gastrectomy for gastric cancer

Abstract

Background

Patients with gastric cancer (GC) are affected by changes in iron status. Before surgery, GC patients are likely to have iron-deficiency anemia; and after gastrectomy, patients suffer from low nutritional status and low iron. This study investigated preoperative iron status associated with prognosis after curative gastrectomy for gastric cancer.

Methods

We evaluated preoperative serum hemoglobin (Hgb), Fe and total iron-binding capacity (TIBC) in 298 patients who underwent curative gastrectomy for GC without preoperative chemotherapy, and analyzed these factors' associations with prognosis after surgery.

Results

Of the 298 patients, 129 (43.2%) had low Hgb levels, and 33 (11.1%) had low TIBC (< 260 µg/dl) that was not associated with Hgb or Fe level. Patients with low TIBC were significantly associated with older age (≥ 65 years old; P = 0.0085), low albumin (< 3.9 g/dl; P = 0.0388) and high CRP (≥ 0.15 mg/dl; P = 0.0018) in multivariate analysis. Low Fe (< 60 µg/dl) was not associated with disease-free survival (DFS) or overall survival (OS); however, low Fe was associated with longer cancer-specific survival in Stage III GC patients (P = 0.0333). Both low Hgb and low TIBC were significantly associated with shorter DFS (Hgb: P = 0.0433; TIBC: P < 0.0001) and shorter OS (Hgb: P = 0.0352; TIBC: P < 0.0001). Low TIBC were significantly associated with shorter DFS (HR 2.167, 95% CI 1.231–3.639, P = 0.0086) and shorter OS (HR 2.065, 95% CI 1.144–3.570, P = 0.0173) in multivariate Cox hazard regression analysis.

Conclusions

Preoperative serum TIBC level of GC patients who undergo curative gastrectomy is a novel prognostic marker in univariate and multivariate analyses.
