Erythropoietin-alfa During Neoadjuvant Chemotherapy for Locally Advanced Esophagogastric Adenocarcinoma

Background In a previous study we showed that many patients with esophagogastric adenocarcinoma experience anemia during neoadjuvant chemotherapy. We now investigated the role of erythropoietin in managing anemia during neoadjuvant chemotherapy. Methods Patients with esophagogastric adenocarcinoma who experienced anemia (hemoglobin < 12 g/dL) during neoadjuvant treatment received erythropoietin 10,000 IE subcutaneously three times a week. Primary outcomes were the response to erythropoietin, safety, the need for allogeneic red blood cell transfusion, and the rate of postoperative complications. Results Between April 2003 and December 2004, 24 patients (median age, 62 years) were enrolled. The mean hemoglobin level before chemotherapy was 12.5 g/dL and the mean hemoglobin level before patients received erythropoietin was 11.5 g/dL. One year after involvement in the trial, 4 of 17 analyzable patients were still anemic (hemoglobin level < 12 mg/dL). Twenty-two patients received erythropoietin, and 16 (73%) responded. We could observe a significant increase in hemoglobin concentrations under therapy with erythropoietin to 12.6 g/dL (p < 0.001). Two patients (8%) received allogeneic transfusions; the rate of postoperative complications was 16%. There were no erythropoietin-related adverse events. Conclusions Treatment with erythropoietin is effective and well tolerated in patients with esophagogastric adenocarcinoma who experience anemia during neoadjuvant chemotherapy.
