Background: In primary cutaneous B-cell lymphomas (PCBCL), radiotherapy - or surgery in a minority of cases - is the first-line treatment in follicle center lymphoma (PCFCL) and marginal zone B-cell lymphoma (PCMZL). Conversely, patients with multifocal skin involvement or relapsed/refractory disease deserve a systemic chemotherapy. In diffuse large B-cell lymphoma, leg type (PCLBCL-LT), due its poorer outcome, cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP)-like regimens are the most commonly used frontline, although hard to propose in elderly patients. In this regard, the association of rituximab (R) and pegylated liposomal doxorubicin (PLD) can be considered a promising, alternative approach. Aims: Based on the favorable results reported with R and PLD in several recent trials, we decided to test efficacy and safety of this combination. Methods: Twelve patients with PCBCL were treated with R plus PLD, and 7 had relapsed disease. Treatment plan consisted of 2 monthly cycles of R 375 mg/m2 and PLD 20 mg/m2 day 1;15, followed (in responders) by two cycles given only at day 1. All patients received prophylactic pyridoxine to prevent palmar-plantar erythrodysesthesia (PPE). Results: Ten of 12 patients had a response (eight complete; two partial), remarkably 2/3 with PCLBCL-LT. Two patients did not respond (one progressive disease, PD, and one stable disease). Three patients died after a median follow-up of 56 months, two patients due to PD, and 1 due to a second neoplasm. Two out of 10 responders relapsed after 31 and 32 months, respectively. Hematological toxicity was negligible (one case of grade 2 neutropenia), as well as extra-hematological toxicity (two cases of grade 2 PPE). Conclusions: These preliminary data suggest that R-PLD is effective and well tolerated in all subsets of PCBCL and may be offered frontline in indolent cases unsuitable for radiotherapy or surgery as well as in more aggressive cases with contraindications to CHOP-like regimens.

Abstract

Background: In primary cutaneous B-cell lymphomas (PCBCL), radiotherapy - or surgery in a minority of cases - is the first-line treatment in follicle center lymphoma (PCFCL) and marginal zone B-cell lymphoma (PCMZL). Conversely, patients with multifocal skin involvement or relapsed/refractory disease deserve a systemic chemotherapy. In diffuse large B-cell lymphoma, leg type (PCLBCL-LT), due its poorer outcome, cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP)-like regimens are the most commonly used frontline, although hard to propose in elderly patients. In this regard, the association of rituximab (R) and pegylated liposomal doxorubicin (PLD) can be considered a promising, alternative approach. Aims: Based on the favorable results reported with R and PLD in several recent trials, we decided to test efficacy and safety of this combination. Methods: Twelve patients with PCBCL were treated with R plus PLD, and 7 had relapsed disease. Treatment plan consisted of 2 monthly cycles of R 375 mg/m2 and PLD 20 mg/m2 day 1;15, followed (in responders) by two cycles given only at day 1. All patients received prophylactic pyridoxine to prevent palmar-plantar erythrodysesthesia (PPE). Results: Ten of 12 patients had a response (eight complete; two partial), remarkably 2/3 with PCLBCL-LT. Two patients did not respond (one progressive disease, PD, and one stable disease). Three patients died after a median follow-up of 56 months, two patients due to PD, and 1 due to a second neoplasm. Two out of 10 responders relapsed after 31 and 32 months, respectively. Hematological toxicity was negligible (one case of grade 2 neutropenia), as well as extra-hematological toxicity (two cases of grade 2 PPE).
