Efficacy of ferric carboxymaltose or darbepoetin alfa for chemotherapy-induced anemia in patients with esophagogastric or pancreaticobiliary cancer: a retrospective comparative study.

Both FCM and DA are effective, and FCM showed a higher Hb response than DA for CIA treatment in patients with esophagogastric or pancreaticobiliary cancer. Therefore, further randomized controlled trials should determine the optimal treatment for CIA in patients with these cancers undergoing myelosuppressive chemotherapy.
