NPM-ALK⁺ T-cell anaplastic large-cell lymphoma (ALCL) is an aggressive type of cancer. Standard treatment of NPM-ALK⁺ ALCL is CHOP polychemotherapy. Although patients initially respond favorably to CHOP, resistance, relapse, and death frequently occur. Recently, selective targeting of ALK has emerged as an alternative therapeutic strategy. ASP3026 is a second-generation ALK inhibitor that can o...

Anaplastic lymphoma kinase (ALK) gene rearrangements have been identified in lung cancer at 3-7% frequency, thus representing an important subset of genetic lesions that drive oncogenesis in this disease. Despite the availability of multiple FDA-approved small molecule inhibitors targeting ALK fusion proteins, drug resistance to ALK kinase inhibitors is a common problem in clinic. Thus, there i...

Introduction This study determined the prevalence of anaplastic lymphoma kinase (ALK) rearrangement, and identified the associations of ALK rearrangement with clinicopathologic characteristics and treatment outcomes in patients with surgically-resected stage I-III lung adenocarcinoma. Methods A total of 534 surgically-resected lung adenocarcinoma patients were studied. The prevalence of ALK p...

Brigatinib (AP26113) is a dimethylphosphine oxide group-containing tyrosine kinase inhibitor (TKI) constructed around a bisanilinopyrimidine scaffold with potent activity against the anaplastic lymphoma kinase (ALK) and several other targets. Despite the activity of first- and second-generation ALK inhibitors in advanced ALK-rearranged lung cancers, the development of acquired resistance repres...

Approximately 3-7% of non-small cell lung cancers harbor an anaplastic lymphoma kinase (ALK) gene fusion, constituting a new molecular subtype of lung cancer that responds to crizotinib, an ALK inhibitor. Although previous studies have evaluated ALK-rearranged lung cancers, the comprehensive analysis of lung cancer in Chinese has not well assessed. Herein, we identified 44 cases of ALK-rearrang...

BACKGROUND ALK gene rearrangements as oncogenic drivers have been described in many cancers, including inflammatory myofibroblastic sarcoma (IMS). The first-generation ALK inhibitor was limited in its ability to cross the blood-brain-barrier to treat brain metastasis. Drug-resistance invariably develops over time in ALK-rearranged tumors, which leads to disease progression. The newer generation...

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 antibod...

BACKGROUND Compared with FISH and qRT-PCR analyses, immunohistochemistry (IHC) is the preferred screening test in most pathology practices for ALK-rearrangement detection. With 100% sensitivity and 98% specificity, the VENTANA ALK (D5F3) IHC assay has been approved in the EU and some Asian countries for ALK-rearrangement detection. However, an automated Ventana IHC platform is not available in ...

Primary breast lymphoma represents less than 1% of all primary breast malignancies and most primary breast lymphomas are of B-Cell origin. The association of anaplastic lymphoma kinase (ALK) negative anaplastic large cell lymphoma (ALCL), a very rare form of primary breast lymphoma, with silicone-filled breast implants has been suggested and several case reports supported this proposal, especia...

The clinical efficacy of the ALK inhibitor crizotinib has been demonstrated in ALK fusion-positive NSCLC; however, resistance to crizotinib certainly occurs through ALK secondary mutations in clinical use. Here we examined the efficacy of a selective ALK inhibitor alectinib/CH5424802 in models of crizotinib resistance. Alectinib led to tumor size reduction in EML4-ALK-positive xenograft tumors ...
