A Randomized Phase III Trial to Assess the Effect of Erythropoietin on Local-Regional Control in Anemic Patients Treated With Radiotherapy for Carcinoma of the Head and Neck

Inclusion Criteria

DISEASE CHARACTERISTICS:

- Histologically confirmed invasive squamous cell carcinoma of the head and neck,
including carcinoma arising from the oral cavity, oropharynx, larynx, and hypopharynx

- Stage I-IV disease

- No distant metastases

- No carcinoma of the nasopharynx, nasal cavity/paranasal sinuses, or salivary
glands

- No carcinoma in situ without an identifiable invasive component

- Plan for radiotherapy in continuous course

- Prior surgical exploration with gross residual disease remaining allowed

- Prior neck dissection with or without biopsy of primary tumor, but no radical surgery
for primary tumor, allowed

- Anemia, defined as hemoglobin no greater than 13.5 g/dL for males and no greater than
12.5 g/dL for females (transfusion prior to study allowed)

- No severe anemia (i.e., hemoglobin less than 9.0 g/dL)

- No anemia confirmed to be due to causes other than chronic disease (e.g., iron
deficiency anemia)

- Not entered on other RTOG head and neck protocols

Hematopoietic:

- See Disease Characteristics

- Stage III/IV patients receiving concurrent cisplatin:

Hepatic:

- Not specified

Renal:

- Stage III/IV patients receiving concurrent cisplatin:
