OBJECTIVES: The therapy of advanced, relapsed or refractory primary cutaneous lymphomas is often unsatisfactory. Recent data indicate a favourable pharmacokynetic, pharmacodynamic and toxicity profile of pegylated liposomal doxorubicin (Peg-Doxo) in primary cutaneous T-cell lymphomas, while in primary cutaneous B-cell lymphomas (PCBCLs), the drug efficacy has never been assessed so far.
METHODS: We performed a prospective phase II pilot clinical trial of Peg-Doxo monotherapy (20 mg/m(2)) in PCBCLs. One patient had a marginal zone B-cell lymphoma and four were affected by diffuse large B-cell lymphoma-leg type, all with widespread nodular lesions.
RESULTS: All the patients achieved a complete response (CR = 100%) in a short period of time (median 3 months), even when pretreated with radio-chemotherapy. Two experienced a relapse. At follow-up, one patient died for progressive disease; four are in CR after 5, 52, 63 and 69 months. As concerning the toxicity profile, the treatment was well-tolerated, no one decreased or delayed the dose. The haematological toxicity was mild with only one case of grade III neutropenia; a patient showed a grade I neurotoxicity. Dermatological toxicity, in particular the palmar-plantar erythrodysesthesia, did not occurred, probably because of both the low dosages of Peg-Doxo monotherapy and the oral prophylaxis with pyridoxine.
CONCLUSIONS: In spite of the small number of patients, it emerges that monochemotherapy with Peg-Doxo has a significantly high clinical activity and a good safety profile in PCBCLs, even in aggressive forms, compared with other therapeutic regimens, which are completely reviewed. It suggests the need of further investigations in this field.
