Cancer-related fatigue: clinical practice versus practice guidelines

Area of Science:

• Oncology
• Hematology
• Patient Care

Background:

• Cancer-related anemia and fatigue (CRA/CRF) are common and significantly impact patient quality of life.
• Current treatment guidelines exist for managing CRA/CRF, but adherence in clinical practice requires investigation.

Purpose of the Study:

• To assess adherence to treatment guidelines for cancer-related anemia and fatigue.
• To identify factors influencing the selection of interventions for CRA/CRF.

Main Methods:

• Prospective, observational study of 136 cancer patients undergoing chemotherapy.
• Data collection included patient questionnaires on fatigue (FACIT-Fatigue) and counseling received, alongside medical record abstraction for anemia treatments (epoetin, blood transfusions).

Main Results:

• Guideline adherence for severe anemia (Hb <10 g/dl) was approximately 53%; only 6% of patients with less severe anemia (Hb 10-12 g/dl) received treatment.
• Half of patients with less severe anemia reported clinically significant fatigue.
• Fatigue levels did not significantly correlate with epoetin or blood transfusion use; palliative care, male gender, and very low Hb (<6.2 g/dl) were associated with increased epoetin use.

Conclusions:

• Adherence to guidelines for epoetin or blood transfusion in severe cancer-related anemia is around 50% in clinical practice.
• Fatigue severity did not influence epoetin use in patients with less severe anemia.
• Current counseling for cancer-related fatigue emphasizes energy conservation, contrasting with guidelines recommending activity enhancement, which is provided to a minority of patients.
