The histopathologic spectrum of Spitzoid neoplasms includes Spitz nevi, atypical Spitz tumors, and Spitzoid melanomas. Advances in molecular genetics have evolved to the point that Spitzoid lesions can now be reasonably classified according to their distinctive molecular-genetic alterations: Spitzoid lesions with (1) 11p amplification and/or HRAS mutations; (2) isolated loss of 6q23 by fluorescence in situ hybridization (FISH); (3) homozygous deletion of 9p21 by FISH; (4) BAP1 loss and BRAFV600 E mutation; (5) translocations involving any of a number of different oncogenic kinase drivers, including ROS1, ALK, NTRK1, NTRK3, MET, BRAF, and RET; and (6) TERT promoter mutations...

Choroidal metastasis is rare in cancer patients and it may cause visual disturbances that reduce their quality of life. In non-small cell lung cancer (NSCLC), targeted therapy against actionable driver mutations has gradually replaced radiotherapy as the treatment of choice for choroidal metastasis. Recently, there have been several case reports of choroidal metastasis in patients with anaplastic lymphoma kinase (ALK)-rearranged NSCLC. We herein report the case of a 40-year-old Japanese woman diagnosed with choroidal metastasis of an ALK-rearranged NSCLC who received alectinib as the first-line chemotherapy...

Cytotoxic chemotherapy remains the core treatment strategy for patients with advanced non-small cell lung cancer (NSCLC) with tumours that do not have actionable molecular alterations, such as epidermal growth factor receptor (EGFR)-sensitising mutations, anaplastic lymphoma kinase (ALK) translocations or ROS1 translocations. Age and performance status (PS) are two pivotal factors to guide treatment decisions regarding the use of chemotherapy in lung cancer patients. Lung cancer is predominantly a disease of the elderly, with more than two-thirds of patients aged ≥65 years, the current definition of 'elderly'...

The anaplastic lymphoma kinase (ALK) was initially identified as a fusion partner of the nucleophosmin gene in anaplastic large cell lymphoma (ALCL) with t(2;5)(p23;q35) translocation, and then described with different genetic abnormalities in a number of tumors. Although ALK is known to be involved in the pathogenesis of neuroblastoma through activating mutations or gene amplification, its role in the pathogenesis of other pediatric cancers is still elusive. In addition to neuroblastoma, the high-grade amplification of ALK has been described in a subset of rhabdomyosarcoma cases...

We report on a patient with lung adenocarcinoma and a concomitant epithelial growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) translocation who developed a disease flare after discontinuing gefitinib. A 63-year-old woman with lung adenocarcinoma and a concomitant activating EGFR mutation and ALK translocation was treated with first-line gefitinib. After 4 months, she discontinued the gefitinib due to disease progression. She was admitted to the emergency room complaining of severe dyspnea and back pain 22 days after discontinuing gefitinib...

Fluorescence in situ hybridization (FISH) is an essential tool for genetic diagnosis in daily pathological work. Almost full automation of FISH can be achieved with the recently released automated SureFISH platform (Dako Omnis, Agilent Technologies, Santa Clara, CA, USA). Its utility has been reported in HER2 amplification of breast and gastric carcinoma and ALK-rearranged lung cancer. Here, we examined the utility of automated SureFISH for the identification of rearrangement signals in translocation-related sarcomas (TRSs), including 11 EWSR1-rearranged and 10 synovial sarcoma cases, compared with non-automated conventional FISH using the same specimens...

Inflammatory myofibroblastic tumor (IMT) of the female genital tract is under-recognized. We investigated the prevalence of ALK-positive IMT in lesions previously diagnosed as gynecologic smooth muscle tumors. Immunohistochemistry (IHC) for ALK was performed on tissue microarrays of unselected tumors resected from 2009 to 2013. Three of 1176 (0.26%) "leiomyomas" and 1 of 44 (2.3%) "leiomyosarcomas" were ALK IHC positive, confirmed translocated by fluorescence in situ hybridization (FISH) and therefore more appropriately classified as IMT...

A 62-year-old female patient with renal dysfunction and pulmonary adenocarcinoma developed postoperative recurrence and received carboplatin/pemetrexed and maintenance pemetrexed. As an anaplastic lymphoma kinase (ALK) gene translocation was identified, the therapy was changed to crizotinib. However, the patient's blood creatinine level increased, and her physical status worsened. Alectinib also induced exacerbation of renal dysfunction but was controlled by dose reduction of 140 mg twice daily for 2 weeks treatment and 2 weeks break were repeated, and exhibited a partial response for 16 months...

With an incidence of 68 new cases per 100,000 people per year, an estimated total number of up to 350,000 new non-small-cell lung cancer (NSCLC) cases are diagnosed each year in the European Union. Up to 10% of NSCLC patients are eligible for therapy with novel ALK (anaplastic lymphoma kinase) inhibitors, as they have been diagnosed with a mutation in the gene coding for ALK. The ALK inhibitor therapy costs add up to approx. 9,000 € per patient per month, with treatment durations of up to one year. Recent studies have shown that up to 10% of ALK cases are misdiagnosed by nearly 40% of pathologic investigations...

Primary gastrointestinal anaplastic large cell lymphoma (GI-ALCL) is rare. We report eight new cases. The median age was 61.5 years (range 10-88), most frequently involving the stomach (n = 3) and small intestine (n = 4). The neoplastic hallmark cells in all cases expressed CD30. Anaplastic lymphoma kinase (ALK) protein was expressed in two cases (25%). By in situ hybridisation, all cases were negative for Epstein-Barr virus and for DUSP22/IRF4 gene translocation. At a median follow-up time of 37.5 months, four patients died of disease, one was alive with disease, and three were disease-free...

Anaplastic lymphoma kinase (ALK) protein is an orphan receptor tyrosine kinase that is constitutively activated by aberrant translocations of the ALK gene in anaplastic large cell lymphoma, ALK-positive and several other cancers. Additionally, aberrant mutation and amplification of the ALK gene, resulting in ALK kinase activation, were detected mainly in neuroblastoma. Recently, truncated ALK protein was also reported in neuroblastoma. Here, we describe a novel truncated form of the ALK transcript with in-frame skipping through exons 2 to 17 (ALKΔ2-17) in anaplastic large cell lymphoma, ALK-positive...

We have previously shown that cancer stem-like cells (CSLCs) can mediate therapy resistance in ALK translocated lung cancers. HER2 has been linked to CSLCs in breast cancers and, therefore, we wanted to assess whether HER2 has a role in CSLCs in ALK translocated cancers. ALK translocated cell lines, H3122 and H2228, with variable sensitivity to ALK inhibition were used in the study. HER2 overexpression or knockdown was induced by retro- or lentiviral infections and cells were treated with pharmacological agents targeting HER2 and ALK signaling...

PURPOSE: To establish a baseline for care and overall survival (OS) based upon contemporary first-line treatments prescribed in the era before the introduction of immune checkpoint inhibitors, for people with metastatic non-small cell lung cancer (NSCLC) without common actionable mutations. METHODS: Using a nationally representative electronic health record data from the Flatiron dataset which included 162 practices from different regions in US, we identified patients (≥18 years old) newly diagnosed with stage IV NSCLC initiating first-line anticancer therapy (November 2012- January 2015, with follow-up through July 2015)...

BACKGROUND: Erlotinib has been approved for the management of NSCLC patients after failure of the first or subsequent line of chemotherapy. Although the efficacy of erlotinib is clearly associated with the presence of EGFR mutations, there is a subset of patients with EGFR wild-type (EGFRwt) tumors who impressively respond. PATIENTS AND METHODS: Patients with EGFRwt NSCLC who received salvage (≥2nd line) treatment with erlotinib for a prolonged period (>6 months), were sought from the database of the Hellenic Oncology Research Group...

Patients with lung cancer who show EML4-ALK translocation are routinely treated with ALK tyrosine kinase inhibitors, although in the majority of cases, these patients develop resistance over time. The central nervous system is a common of site of recurrence in this population, which calls for next-generation drugs that can penetrate into the brain and achieve clinically meaningful central nervous system activity. Here, I report the case of a female patient diagnosed with adenocarcinoma of the lung in 2005, at the age of 46 years, who underwent lobectomy and then experienced a series of progression episodes 6 years later...

Immune checkpoint inhibitors, notably antibodies targeting programmed death-1 (PD-1) and programmed death ligand-1 (PD-L1), have modified the management of patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC). Several PD-1/PD-L1 inhibitors have been approved by health authorities for this indication and others are in clinical development. However, only a subset of patients truly benefits from these agents. For patients with mutated EGFR or translocated ALK NSCLC, for whom an immune checkpoint inhibitor can be prescribed after progression on tyrosine kinase inhibitors and chemotherapy, information is scarce and sometimes contradictory...

Genomic analysis has greatly influenced the diagnosis and clinical management of patients affected by diverse forms of hematologic malignancies. Here, we review how genetic alterations define subclasses of patients with acute leukemias, myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPNs), non-Hodgkin lymphomas, and classical Hodgkin lymphoma. These include new subtypes of acute myeloid leukemia defined by mutations in RUNX1 or BCR-ABL1 translocations as well as a constellation of somatic structural DNA alterations in acute lymphoblastic leukemia...
