epoetin-alfa and Esophageal-Neoplasms

This prospective, nonrandomized study evaluates the effectiveness of epoetin alfa to maintain the hemoglobin levels at 12 to 14 g/dL (optimal range for tumor oxygenation) during chemoradiation for Stage III esophageal cancer and its impact on overall survival (OS), metastatic-free survival (MFS), and locoregional control (LC).. Ninety-six patients were included. Forty-two patients received epoetin alfa (150 IU/kg, 3 times a week) during radiotherapy, which was started at hemoglobin less than 13 g/dL and stopped at 14 g/dL or higher. Hemoglobin levels were measured weekly during RT.. Both groups were balanced for age, sex, performance status, tumor length/location, histology, grading, T-stage/N-stage, chemotherapy, treatment schedule, and hemoglobin before RT. Median change of hemoglobin was +0.3 g/dL/wk with epoetin alfa and -0.5 g/dL/wk without epoetin alfa. At least 60% of hemoglobin levels were 12 to 14 g/dL in 64% and 17% of the patients, respectively (p < 0.001). Patients who received epoetin alfa had better OS (32% vs. 8% at 2 years, p = 0.009) and LC (67% vs. 15% at 2 years, p = 0.001). MFS was not significantly different (42% vs. 18% at 2 years, p = 0.09).. The findings suggest that epoetin alfa when used to maintain the hemoglobin levels at 12 to 14 g/dL can improve OS and LC of Stage III esophageal cancer patients.

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.. 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.. 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.. Treatment with erythropoietin is effective and well tolerated in patients with esophagogastric adenocarcinoma who experience anemia during neoadjuvant chemotherapy.

It has been suggested that hemoglobin levels of 12-14 g/dL are optimal for tumor oxygenation, radiosensitivity, and prognosis. In this prospective study, the authors evaluated the effectiveness of epoetin-alpha to maintain hemoglobin levels at 12-14 g/dL during radiotherapy (RT) for patients with UICC Stage III esophageal carcinoma, and they examined the impact of erythropoetin on overall survival (OS), metastatic-free survival (MFS), and local control (LC).. Sixty patients who received RT between March, 2001 and September, 2004, were included in this prospective, nonrandomized study. Thirty patients received epoetin-alpha (150 IU/kg 3 times per week) during RT (Group A), and 30 patients did not receive epoetin-alpha (Group B). Epoetin-alpha was started at hemoglobin levels < 13 g/dL and was stopped at hemoglobin levels > or = 14 g/dL. Hemoglobin was measured before RT and once weekly during RT.. Both patient groups were balanced for age, gender, performance status, tumor location/length, histology, grading, tumor classification, lymph node status, chemotherapy, treatment (45-50.4 grays [Gy] plus resection vs. 45.0-50.4 Gy vs. 59.4-66.0 Gy), and hemoglobin level before RT. In 20 of 30 patients (67%) from Group A and in 3 of 30 patients (10%) from Group B, > or = 60% of hemoglobin levels during RT were 12-14 g/dL (P = 0.003). The median change in hemoglobin was + 0.4 g/dL per week in Group A and - 0.4 g/dL per week in Group B. LC was significantly better in Group A (66% vs. 38% at 1 year, respectively; P = 0.012), a trend was observed for OS (59% vs. 33%, respectively; P = 0.08), and MFS did not differ significantly (43% vs. 38%, respectively; P = 0.34). No epoetin-alpha-related toxicity was observed.. Epoetin-alpha was effective in maintaining the hemoglobin levels at 12-14 g/dL during RT. The application of epoetin-alpha significantly improved LC, and a trend was observed for OS.
