PURPOSE: Recombinant human erythropoietin (r-Hu-EPO) is known to be
effective in untreated cancer patients. Here we assess the possibility that
r-Hu-EPO may also prevent or reduce anemia in patients who receive
cytotoxic chemotherapy. METHODS: Thirty-six patients with small-cell lung
carcinoma (SCLC) were enrolled onto a three-arm, randomized trial to
investigate the effect of r-Hu-EPO on hemoglobin (Hb) levels and RBC and
platelet (Plt) transfusions during chemotherapy. Bone marrow progenitors
were studied before and after treatment. Two groups of patients received
r-Hu-EPO at a dose of either 150 IU/kg (group 150) or 300 IU/kg (group 300)
three times per week for the duration of chemotherapy. A control group did
not receive r-Hu-EPO (group O). A maximum of six cycles of a chemotherapy
regimen that consisted of vincristine, ifosfamide, carboplatin, and
etoposide (VICE) were given to all patients. Hematologic parameters were
measured weekly, and RBC or Plt transfusions were given for Hb levels less
than 9 g/dL and Plt counts less than 20 x 10(9)/L. RESULTS: Hb levels
decreased in all patients, but onset of anemia was delayed in groups that
received r-Hu- EPO (P = .002). A total of 116 U RBC were transfused in
group 0, 54 in group 150, and 52 in group 300 (P = .017). In addition,
there was a nonsignificant trend toward higher Plt counts and fewer Plt
transfusions in patients who received r-Hu-EPO. CONCLUSION: r-Hu-EPO at a
dose of either 150 or 300 IU/kg three times weekly delays the onset of
anemia and reduces RBC transfusion requirements in patients who undergo
intensive chemotherapy for SCLC. A possible effect of r-Hu-EPO on platelet
numbers deserves further study.
