Clinical Characteristics and Treatment Response of Hodgkin's Lymphoma in Taiwan

Background/PurposeHodgkin's lymphoma (HL) is particularly rare in Asia, including Taiwan. The report concerning its clinical features and treatment outcomes in Asians is limited. An exploration of the characteristics of HL in this area is of importance for future studies.MethodsIn this study, 133 patients with HL diagnosed between January 1985 and December 2004 at National Taiwan University Hospital were analyzed retrospectively.ResultsThe age distribution revealed a young-adult peak at the age around 20 years. The nodular sclerosis type (NS-HL) was the most common histopathogic subtype (45%), followed by mixed cellularity (29%), lymphocyte predominant (13%), and lymphocyte depleted subtype (2%). The incidence of NS-HL was, however, lower compared with that in the West (around 70%). The male to female ratio was approximately 1:2 in patients with NS-HL, in contrast to the male predominance in patients with other subtypes. Induction therapy led to complete remission (CR) in 87% of patients. At a median follow-up of 78 months, the 10-year overall survival (OS) was 79% in all HL patients and was 90% in those who achieved first CR. In multivariate analysis, the achievement of CR was the only independent factor associated with good OS.ConclusionThe treatment response of HL in Taiwan is good and comparable to that in Western countries. The epidemiologic differences between Taiwan and the West mandate further studies
