Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase that has been implicated in the pathogenesis of a variety of neoplasms. As suggested by its name, ALK was first described as part of a translocation product in cases of anaplastic large-cell lymphoma, with other genetic and cytogenetic ALK mutations subsequently coming to attention in the development of many other hematologic and so...

Anaplastic large cell lymphoma (ALCL) is an uncommon form of non-Hodgkin lymphoma in younger patients, accounting for less than 15% of cases. It is exceedingly rare in infants, with a median age at diagnosis of 12 years. Various treatment strategies have been studied in pediatric ALCL, however the long-term event free survival is approximately 70% regardless of treatment approach. We present th...

A case of Ki-1-positive anaplastic large cell lymphoma of the pancreas is presented. The patient complained of abdominal pain and was jaundiced. Examination of a biopsy specimen obtained by duodenal endoscopy revealed malignant lymphoma, and surgery confirmed a large mass located in the region from the intra-pancreatic tissue around the lower common bile duct to the peri-pancreatic lymph nodes....

Background & Objectives: Anaplastic lymphoma Kinase (ALK) is a receptor tyrosine kinase involved in the genesis of several human cancers. ALK was initially identified because of its involvement in anaplastic large cell lymphoma (ALCL). ALK is believed to foster tumorigenesis following activation by autocrine and/or paracrine growth loops. Studies reveal that the presence of anti-ALK antibodies ...

CD30, a non-death domain-containing member of the tumor necrosis factor receptor superfamily, triggers apoptosis in anaplastic large cell lymphoma cells. The CD30 signaling pathways that lead to the induction of apoptosis are poorly defined. Here, we show that the induction of apoptosis by CD30 requires concurrent inhibition of p38 mitogen-activated protein kinase, which itself is activated by ...
