OBJECTIVES: Primary * Determine the rate of Epstein-Barr virus (EBV) lytic phase activation by BZLF1 expression in patients with relapsed or refractory, EBV-positive malignancies treated with phenylbutyrate. Secondary * Determine tumor responses in patients treated with phenylbutyrate followed by valganciclovir. * Track serum EBV load by quantitative polymerase chain reaction and correlate changes with EBV lytic phase activation/tumor response. OUTLINE: This is an open-label study. Patients receive oral phenylbutyrate three times daily on days 1-21 and oral valganciclovir once or twice daily on days 4-21. Treatment repeats every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Patients undergo biopsy on day 3 of course 1. Serum Epstein-Barr virus DNA is analyzed for expression of BZLF1 and LMP2 by quantitative polymerase chain reaction on days 3 and 14 of course 1 and on day 1 of each subsequent course. After completion of study treatment, patients are followed at 1 and 3 months. PROJECTED ACCRUAL: A total of 14 patients will be accrued for this study.
