title: [Lymphomas in adolescents: are childhood lymphoma therapy protocols suitable for this patient group?].
abstract: The centres of the Hungarian Paediatric Oncology Network annually take care of 250-300 new patients with childhood cancer, every tenth of them suffering from lymphoma. The aim of our work was to analyse the data of the adolescents (14-19 years) with Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL), comparing their survival rates with younger patients under fourteen and with the international data. From January 1990 to December 2004 there were 281 children diagnosed with HL and 230 with NHL. Among the HL patients 107, while among the NHL patients 51 were older than 14 years old. In the group of HL the distribution of patients according to the stage was similar in younger and older patients. In the NHL group 55% of the children younger than 14, and 72% of the patients older than 14 years old had advanced stage disease (stage III or IV). In both groups the patients received chemotherapy according to the current paediatric protocols. The overall survival (OS) of the HL patients younger than 14 was 92.5+/-2% at 5 years and 90.3+/-2% at 10 years, and for the adolescents 93.4+/-2% and 90.7+/-3% at 5 and 10 years (n.s.). The OS of the younger children in the NHL group was 78.2+/-3% at 5 and 10 years, and 77.9+/-6% for the adolescents (n.s.). As a conclusion, survival rates of the adolescents do not differ significantly from the parameters of the patients under fourteen, so the therapy protocols used for childhood lymphomas are suitable for the treatment of the lymphomas appearing at the age of 14-19 years.
