• Response rate [ Designated as safety issue: No ]

OBJECTIVES:

• Determine the response rate and time to progression in patients with relapsed or refractory low-grade non-Hodgkin's lymphoma treated with thalidomide.
• Determine the effect of this drug on microvessel density in bone marrow and basic fibroblast growth factor levels in serum and urine in these patients.

OUTLINE: Patients receive oral thalidomide once daily. Treatment continues in the absence of disease progression or unacceptable toxicity.

Patients are followed every 6 months for 2 years and then annually for 3 years.

PROJECTED ACCRUAL: A total of 21-45 patients will be accrued for this study.

DISEASE CHARACTERISTICS:

• Histologically confirmed relapsed or refractory low-grade non-Hodgkin's lymphoma of 1 of the following subtypes:

  • Follicular grades I, II, or III
  • B-cell small lymphocytic lymphoma

• Bidimensionally measurable disease

  • Greater than 1 cm in each dimension by physical exam, x-ray, MRI, or CT scan

  • The following are not considered measurable:

    • Barium studies
    • Ascites or pleural effusions
    • Bony disease
    • Bone marrow
• No marginal zone lymphoma
• No known lymphomatous involvement of the CNS, including parenchymal or leptomeningeal involvement NOTE: A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. However, this protocol uses the former terminology.
