Abstract

Although PTCL in children, as in adults, has a spectrum of clinical, morphologic, cytogenetic and immunologic features, there are several significant differences in these features between children and adults. Our data show that CD30 expression is much more common in pediatric PTCL than is reported in adult PTCL. Furthermore, the majority of children with CD30-positive PTCL do not have tumors with anaplastic large cell histology. Our data also suggest that the t(2;5) is not a specific marker of anaplastic large cell lymphoma in childhood. The likelihood of cure for children with PTCL is unclear, predominately because of the lack of large numbers of pediatric patients with this less common entity. As with other NHL, we expect that treatment with conventional dose chemotherapy following relapse will be unsuccessful in most cases. Although the data are preliminary, it appears that high dose chemo-radiotherapy followed by hematopoietic stem cell transplantation is an effective therapy in these patients. We have been particularly successful with a regimen based on thioTEPA, VP-16 and total body irradiation, but other regimens may also be efficacious. Further studies of this interesting group of tumors are clearly needed.
