The main aim of this study is to observe correction of the hemoglobin level in the patients under chemotherapy, treated with epoetin alfa biosimilar and presenting with a solid tumor or a lymphoma or a myeloma.

This is a non-interventional, descriptive, national, multi-site, longitudinal and prospective observational study with adults patients who are suffering from cancer or malignant blood disease and whose chemotherapy treatment has induced symptomatic anemia and being treated with biosimilar of epoetin to correct haemoglobin levels.

Inclusion Criteria:

• Patients of more than 18 years of age

• Patients presenting with anemia following chemotherapy

• Patients suffer from solid tumours, malignant hemopathies, lymphomas or myelomas and presenting with anemia following chemotherapy

  -- The patients may be included regardless of their chemotherapy cycle (from the first cycle until the last cycle)

• Patients eligible for epoetin alfa biosimilar treatment

Exclusion Criteria:

• Patients are not receiving chemotherapy
• Patients already included in an epoetin zeta trial
• Patients presenting with a contraindication to epoetin zeta
• Patients presenting with hypersensitivity to the active principle or any of the excipients
• Patient with erythroblastopenia or acquired pure red cell aplasia (APRCA)
• Patient with uncontrollable arterial hypertension
• Patients who cannot receive adequate prophylaxis by antithrombotic agents

Patients suffer from solid tumours, malignant lymphomas or multiple myeloma and have developed symptomatic anaemia due to their chemotherapy.
