CD30+ cutaneous lymphoproliferative disorders: the Stanford experience in lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma

BACKGROUND: CD30+ cutaneous lymphoproliferative disorders (CLPDs) include lymphomatoid papulosis, borderline cases of CD30+CLPDs, and primary cutaneous anaplastic large cell lymphoma (PCALCL). Prior studies have shown CD30+CLPDs have an excellent prognosis. OBJECTIVE: We sought to present the single-center experience of Stanford University, Stanford, Calif, in the management of CD30+CLPDs. METHODS: A retrospective cohort analysis of 56 patients with CD30+CLPDs treated at our institution was performed. RESULTS: No patients with lymphomatoid papulosis died of disease, and overall survival was 92% at 5 and 10 years. Disease-specific survivals at 5 and 10 years for PCALCL were 85%. Disease-specific survival at 5 years for localized versus generalized PCALCL was 91% versus 50% (P =.31). PCALCL was highly responsive to treatment, but the relapse rate was 42%. In all, 3 patients progressed to extracutaneous stage of disease. No clinical or histologic factors analyzed were predictive of worse outcome in lymphomatoid papulosis and PCALCL. CONCLUSION: Similar to prior reports from multicenter European groups, the single-center experience at our institution demonstrates CD30+CLPDs have an overall excellent prognosis; however, cases of PCALCL with poor outcome do exist.
