Brief summary:
RATIONALE: Cyclosporine may help the immune system slow the growth of angioimmunoblastic T-cell lymphoma.

PURPOSE: This phase II trial is studying how well cyclosporine works in treating patients with recurrent or refractory angioimmunoblastic T-cell lymphoma.

Detailed description:
OBJECTIVES:

Primary

* Determine the response rate (complete and partial) in patients with recurrent or refractory angioimmunoblastic T-cell lymphoma treated with cyclosporine.

Secondary

* Determine the disease-free, progression-free, and overall survival of patients treated with this drug.
* Determine the toxicity of this drug in these patients.

OUTLINE: Patients receive oral cyclosporine twice daily for up to 36 weeks in the absence of unacceptable toxicity or disease progression during weeks 1-6. Patients experiencing disease progression during weeks 7-36, receive an additional 36 weeks of therapy.

Patients are followed every 3 months for 2 years and then every 6 months for 1 year.

PROJECTED ACCRUAL: A total of 27 patients will be accrued for this study within 2.5 years.

Arms:
arm 1: High dose cyclosporine weeks 1-6, then maintenance dose cyclosporine weeks 7-36. If CR, PR, or SD at week 36 evaluation, treatment is complete. If progression occurs during weeks 7-36, patients will re-register to Step 2 at time of PD and begin high dose therapy (weeks 1-6), followed by maintenance therapy (weeks 7-36). At second progression patients will end protocol treatment.

Interventions: intervention 1: cyclosporine
Intervention descriptions: intervention 1: Cyclosporine doses will be based on actual body weight unless actual body weight is \> 15 kg higher than the ideal body weight. Cyclosporine dose will be adjusted to maintain a trough whole blood level of 250-450 ng/mL during the high dose period (weeks 1 -6, starting dose will begin at cyclosporine 3 mg/kg by mouth two times a day (PO BID)) and 150-250 ng/mL during the maintenance period (weeks 7-36, maintenance dose will begin at cyclosporine 2 mg/kg PO BID) in the absence of renal toxicity
