Anaplastic lymphoma kinase (ALK), which belongs to the insulin receptor tyrosine kinase superfamily, plays an important role in nervous system development. Due to chromosomal translocations, point mutations, and gene amplification, constitutively activated ALK has been implicated in a variety of human cancers, including anaplastic large-cell lymphoma (ALCL), non-small cell lung cancer, and neuroblastoma. We evaluated the anti-cancer activity of the ALK inhibitor KRCA-0008 using ALCL cell lines that express NPM (nucleophosmin)-ALK. KRCA-0008 strongly suppressed the proliferation and survival of NPM-ALK-positive ALCL cells. Additionally, it induced G0/G1 cell cycle arrest and apoptosis by blocking downstream signals including STAT3, Akt, and ERK1/2. Tumor growth was strongly suppressed in mice inoculated with Karpas-299 tumor xenografts and orally treated with KRCA-0008 (50 mg/kg, BID) for 2 weeks. Our results suggest that KRCA-0008 will be useful in further investigations of ALK signaling, and may provide therapeutic opportunities for NPM-ALK-positive ALCL patients.

Sweet syndrome (SS), which is characterised by fever and erythematous tender skin lesions, has been shown to be associated with lymphoma. However, there are limited reported experiences on the wound care of SS in patients with lymphoma. This case report presents the wound care of SS in a patient with anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma (ALK+ALCL).

A 32-year-old man had recurrent abdominal pain and vomiting for 2 weeks. Physical examination revealed a 4×2-cm abdominal tough mass with unclear boundaries. Palpation caused mild tenderness without rebound pain.

While ALK-specific CD8+ T cells and epitopes presented on MHC class I have been identified in patients with ALK-positive malignancies, little is known about ALK-specific CD4+ T cells. We screened peripheral blood of ten ALK-positive anaplastic large cell lymphoma (ALK+ALCL) patients in remission and six healthy donors for CD4+ T-cell responses to the whole ALK-fusion protein, nucleophosmin (NPM1)::ALK.

T-cell lymphomas (TCLs) are rare and aggressive malignancies associated with poor outcomes, often because of the development of acquired drug resistance as well as intolerance to the established and often toxic chemotherapy regimens in elderly and frail patients. The many subtypes of TCL are well established to exhibit marked geographic variation. The epidemiology, clinical presentation, diagnosis, prognosis, and treatment of TCLs in the Middle East (ME) are yet to be explored; hence, limited data are available about these entities in this part of the world.
