Abstract

Clinicopathological features of nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) differ from those of the classical Hodgkin lymphoma (cHL). Our aim was to examine clinical presentation, therapeutic and survival results of NLPHL patients in Hungary based on the data of two centres, and incidentally we analyzed the clinicopathological characteristics and differential diagnostic difficulties of this rare entity. We analyzed the clinical features, treatment and survival data of 536 Hodgkin lymphoma patients who had been diagnosed and primarily treated in our institutes between 1995 and 2004. Mean follow-up time was 82.7 (3–144) months of the total 536 HL patients. Sixteen (3%) of the patients were diagnosed with NLPHL, 93% of them presented with early-stage disease. None of the patients showed extranodal or splenic involvement or bulky disease. One patient received chemotherapy alone, six received only involved field radiotherapy while six underwent combined modality treatment. We applied watch and wait strategy in three cases. Overall response rate was 100% (93.75% complete). Two NLPHL cases transformed to non-Hodgkin’s lymphoma. In contrast to the classical HL, the 10-year prognosticated overall survival rate was 100 vs. 82%, the event free survival was: 75% vs. 70%. In NLPHL group there were no late or multiple relapses and none of them died. Conclusions: NLPHL is a rare disease, thus these are limited experiences with its diagnosis and treatment. Since the disease has an excellent outcomeit is very important to prefer less toxic or local therapies to reach long term survival similar to that of the normal population.
