Jeong and colleagues [37] observed a mean increase of Hb of 3.2 g/dL in patients with gastric carcinoma who received IV iron sucrose every other day in 300 mg doses until total target dosage was given (target dosage calculation can be found in Table 1) compared to an increase of 2.5 g/dL in the no specific treatment group (p = 0.029) six months post-operatively (treatment was initiated post-operatively). The gene discussed is GSTM1; the disease is gastric carcinoma.
