Pentostatin (2'-deoxycoformycin) in the treatment of cutaneous T-cell lymphoma.
BACKGROUND: The treatment of patients with advanced or therapy-refractory cutaneous T-cell lymphoma (CTCL) remains a challenge. Pentostatin is a potent inhibitor of adenosine deaminase and is selectively toxic to lymphocytes. In a small number of patients with CTCL, it previously has been shown to be effective. OBJECTIVE: Our purpose was to evaluate the efficacy and safety of pentostatin in the treatment of patients with advanced and/or therapy-refractory CTCL. METHODS: Eighteen patients with stage I to IVb CTCL were treated with 4 to 5 mg/m2 of intravenous pentostatin every 1 to 4 weeks. RESULTS: Two patients (11%) had complete responses of 4 months and 6 years, respectively. These patients had stage III and IVa CTCL and had previously received many different external or systemic treatments. Partial remission (50% to 99% clearing) lasting for 1.5 to 6 months occurred in five patients (28%) with stage IIa (n = 3), stage IIb, and stage IVa CTCL. These patients had received a median of three prior external or systemic treatments. No major side effects were observed, and bone marrow suppression was mild. CONCLUSION: Single-agent pentostatin in intravenous doses of 4 to 5 mg/m2 is an effective systemic treatment of CTCL (39% objective response rate) with little toxicity.
