    Anaplastic lymphoma kinase (ALK) positive Anaplastic large cell lymphoma (ALCL) represents approximately 2% of all Non-Hodgkin’s lymphomas that commonly involves nodal as well as a wide variety of extra nodal sites, as skin, soft tissue, bones and lungs, although primary or secondary involvement of bone is rare. Herein, we report a case of 14-year-old female child presented as extensive bony involvement with a clinical diagnosis of bone tumour/ small round cell tumour, which was proved to be ALK positive ALCL on histopathological examination.

    Primary bone lymphoma (PBL) is an uncommon extra nodal disease that represents about 1–3% of lymphoma cases. Imaging findings are variable and non-specific. Computed tomography may demonstrate lytic lesions with sequestra and periosteal reaction. On magnetic resonance imaging, lesions are T1WI hypointense and T2WI hyperintense, related to peritumoral edema or bone marrow replacement. Rarely lesions may have associated fibrosis and show a more hypointense signal pattern on T2WI. After administration of contrast, PBL tends to enhance avidly. We present a case of a 24 years old African American female patient with history of back pain. Initial imaging examinations showed lesions involving the T12 and T11 vertebral bodies with initial negative biopsy results. One month later, the patient returned with worsening back pain, and the follow up studies depicted collapse of the T12 vertebral body. A diagnosis of anaplastic large cell lymphoma in T12 was made. A brief review of the literature, imaging and pathological findings, and treatment options are also discussed. PMID:27761194

    Abstract Rationale: Anaplastic large cell lymphoma (ALCL) is an aggressive non-Hodgkin lymphoma. It mostly invades lymph nodes with extranodal involvement observed in the soft tissue, bone, and skin. Patient concerns: We report a 34-year-old Chinese male patient who presented with headache, diplopia, and vomit. Cerebrospinal fluid (CSF) analysis via lumbar puncture showed elevated CSF pressure, elevated CSF protein concentrations, decreased CSF glucose and chloride concentration significantly, and pleocytosis of 68 to 350 × 106/L, in which lymphocytes and monocytes were predominant. These changes could be suggestive of tuberculous (TB) meningitis. Enhanced magnetic resonance imaging of spinal cord delineated multiple enhancing nodules in spinal cord, cauda equina, and cristae membrane, and multiple abnormal enhancing lesions in bilateral lumbar intervertebral foramen. Diagnoses: Spinal dura mater biopsy and paraffin pathology examination revealed anaplastic lymphoma kinase positive ALCL. Interventions: High-dose methotrexate, cytosine arabinoside craniospinal, and radiotherapy. Outcomes: Last follow-up on September 22, 2015 showed no evidence of tumor recurrence and the lower extremity muscle strength recovered to 4/5. Lessons: ALCL of primary central nervous system is an exceedingly rare tumor, which is usually misdiagnosed as meningitis (especially TB meningitis) according to clinical manifestation and laboratory examination. Thus closely monitoring patient's conditions and timely adjusting therapeutic regimen during treatment are necessary. PMID:27930548

    Anaplastic Lymphoma Kinase-positive Anaplastic Large Cell Lymphomas (ALK+ ALCL) occur predominantly in children and young adults. Their treatment, based on aggressive chemotherapy, is not optimal since ALCL patients can still expect a 30% 2-year relapse rate. Tumor relapses are very aggressive and their underlying mechanisms are unknown. Crizotinib is the most advanced ALK tyrosine kinase inhibitor and is already used in clinics to treat ALK-associated cancers. However, crizotinib escape mechanisms have emerged, thus preventing its use in frontline ALCL therapy. The process of autophagy has been proposed as the next target for elimination of the resistance to tyrosine kinase inhibitors. In this study, we investigated whether autophagy is activated in ALCL cells submitted to ALK inactivation (using crizotinib or ALK-targeting siRNA). Classical autophagy read-outs such as autophagosome visualization/quantification by electron microscopy and LC3-B marker turn-over assays were used to demonstrate autophagy induction and flux activation upon ALK inactivation. This was demonstrated to have a cytoprotective role on cell viability and clonogenic assays following combined ALK and autophagy inhibition. Altogether, our results suggest that co-treatment with crizotinib and chloroquine (two drugs already used in clinics) could be beneficial for ALK-positive ALCL patients. PMID:26338968

    Anaplastic large cell lymphomas are peripheral T-cell lymphomas that are characterized by a proliferation of large anaplastic blasts expressing CD30. In children, systemic anaplastic large cell lymphomas often present at advanced clinical stage and harbor translocations involving the anaplastic lymphoma kinase (ALK) gene leading to the expression of chimeric anaplastic lymphoma kinase (ALK)-fusion proteins. Primary cutaneous anaplastic large cell lymphoma is regarded as an ALK-negative variant confined to the skin and is part of the spectrum of primary cutaneous CD30-positive T-cell lymphoproliferative disorders. Thirty-three of 487 pediatric patients registered within the Anaplastic Large Cell Lymphoma-99 trial (1999 to 2006) presented with a skin limited CD30-positive lympho-proliferative disorder. In 23 of the 33 patients, material for international histopathological review was available, and the cases were studied for histopathological, immunophenotypical and clinical features as well as for breaks within the ALK gene. Five of 23 cases and one additional case (identified after closure of the trial) expressed ALK-protein. Complete staging excluded any other organ involvement in all children. Expression of ALK proteins was demonstrated by immunohistochemistry in all cases and the presence of breaks of the ALK gene was genetically confirmed in 5 evaluable cases. The histopathological and clinical picture of these skin-restricted ALK-positive lymphomas was indistinguishable from that of cutaneous anaplastic large cell lymphoma. Five children presented with a single skin lesion that was completely resected in 4 and incompletely resected in one. Three of these patients received no further therapy, 2 additional local radiotherapy, and one chemotherapy. All children remain in complete remission with a median follow up of seven years (range 1-8 years). We present 6 pediatric cases of ALK-positive primary cutaneous anaplastic large cell lymphomas.

    Anaplastic large cell lymphomas (ALCL) represent a peripheral T-cell lymphoma subgroup, stratified based on the presence or absence of anaplastic lymphoma kinase (ALK) chimeras. Although ALK-positive ALCLs have a more favorable outcome than ALK-negative ALCL, refractory and/or relapsed forms are common and novel treatments are needed. Here we investigated the therapeutic potential of a novel bromodomain inhibitor, OTX015/MK-8628 in ALK-positive ALCLs. The effects of OTX015 on a panel of ALK+ ALCL cell lines was evaluated in terms of proliferation, cell cycle and downstream signaling, including gene expression profiling analyses. Synergy was tested with combination targeted therapies. Bromodomain inhibition with OTX015 led primarily to ALCL cell cycle arrest in a dose-dependent manner, along with downregulation of MYC and its downstream regulated genes. MYC overexpression did not compensate this OTX015-mediated phenotype. Transcriptomic analysis of OTX015-treated ALCL cells identified a gene signature common to various hematologic malignancies treated with bromodomain inhibitors, notably large cell lymphoma. OTX015-modulated genes included transcription factors (E2F2, NFKBIZ, FOS, JUNB, ID1, HOXA5 and HOXC6), members of multiple signaling pathways (ITK, PRKCH, and MKNK2), and histones (clusters 1-3). Combination of OTX015 with the Bruton's tyrosine kinase (BTK) inhibitor ibrutinib led to cell cycle arrest then cell death, and combination with suboptimal doses of the ALK inhibitor CEP28122 caused cell cycle arrest. When OTX015 was associated with GANT61, a selective GLI1/2 inhibitor, C1156Y-resistant ALK ALCL growth was impaired. These findings support OTX015 clinical trials in refractory ALCL in combination with inhibitors of interleukin-2-inducible kinase or SHH/GLI1. PMID:27793034

    ALK positive anaplastic large cell lymphoma is a T-cell lymphoma usually occurring in children and young adults. It frequently involves lymph nodes and extranodal sites and is associated with favorable prognosis. A 20-year old man was admitted for painful mass in the left axilla with overlying skin redness. Clinical presentation and US findings were highly suspicious for sarcoma. Definitive diagnosis was established cytolologically and using ancillary technologies from cytological samples. Fine needle aspiration cytology of tumor mass (lymph node conglomerate and surrounding tissue) show predominance of large, pleomorphic, atypical cells with large nuclei and vacuolised cytoplasm. Atypical cells immunocytochemically were positive for LCA, CD30, CD3, EMA, and ALK; negative for CD15 and CD56. NPM-ALK transcript was detected by reverse transcriptase-polymerase chain reaction (RT-PCT). Molecular analysis of TCRß and TCRγ genes demonstrated clonal TCR genes rearrangement. Complex karyotype with multiple numerical and structural changes was found on conventional cytogenetics. These findings excluded sarcoma and corroborated the diagnosis of ALK positive ALCL. Cutaneous involvement in ALCL can clinically mimic sarcoma, especially in cases with localized disease without B symptoms. In those cases, immunostaining, PCR, and conventional cytogenetics are helpful to exclude sarcoma. Diagn. Cytopathol. 2017;45:51-54. © 2016 Wiley Periodicals, Inc.

    The prognosis of the primary refractory anaplastic lymphoma kinase (ALK+) anaplastic T large cell lymphoma is ominous. The identification of molecular targets with potential to drive oncogenesis remains a cornerstone for the designing of new selective cancer therapies. Crizotinib is a selective ATP-competitive inhibitor for ALK, approved for its use in lung cancer with rearrangements on ALK gene. The reported cases describe the use of crizotinib as a bridging strategy prior to allotransplantation; there are no reported prolonged survivals under monotherapy with Crizotinib. We report a case of a primary refractory ALK+ anaplastic large-cell lymphoma that sustains complete response after 3 years of crizotinib monotherapy. PMID:27441079

    Introduction Most primary stomach lymphomas are now recognized to originate from B-cell. Primary gastric anaplastic lymphoma kinase (ALK)-negative anaplastic large-cell lymphoma (ALCL) as shown in this case is very rare. Case report A 59-year-old man presented with a 1-month history of epigastric pain. Computed tomography showed a tumor in the stomach with perigastric lymphadenopathy. Biopsy of the tumor with gastroendoscopy showed ALCL. Bone marrow aspiration and trephine biopsy showed no infiltration. A diagnosis of primary gastric ALK-negative ALCL was made. The patient was first treated with four cycles of cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) regimen, but his condition did not show improvement. Then he was treated with two cycles of hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone/methotrexate and cytarabine (Hyper-CVAD/MA) regimen. In spite of these treatments, he still died of disease progression. Conclusion The prognosis of ALK-negative ALCLs is usually worse than ALK-positive ALCLs. In this case, the patient was not responsive to a multidrug chemotherapy with CHOP and Hyper-CVAD/MA. PMID:27695344

    Anaplastic large cell lymphoma (ALCL) is a common subtype of the heterogeneous group of peripheral T-cell lymphomas, which is characterized by large pleomorphic cells with strong expression of CD30. Translocations involving ALK, the anaplastic lymphoma kinase gene, are associated with a favorable clinical outcome. Such ALK-positive ALCLs are usually responsive to a multidrug chemotherapy with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone). However, there is no general consensus on the optimal therapy for relapsed or refractory ALCL. We report the case of a 24-year-old male suffering from ALK-positive ALCL with an uncommon manifestation of only extranodal disease in the gastric cardia region that showed primary refractoriness to standard CHOP chemotherapy. A combination therapy consisting of the anti-CD30 drug conjugate, brentuximab vedotin, and classical lymphoma salvage regimen DHAP (cisplatin, high-dose cytarabine and dexamethasone) was administered. Following two treatment cycles in 21-day intervals, the lymphoma showed considerable regression based on imaging diagnostics and no evidence of vital lymphoma in a subsequent biopsy. We did not observe any increase in toxicity; in particular, polyneuropathy and febrile neutropenia were not observed. In summary, we report that the antibody-drug conjugate brentuximab vedotin and a classical regimen used for aggressive lymphoma, DHAP, could be combined as salvage therapy in a case of refractory ALK-positive ALCL. Phase I/II studies will be required for safety and efficacy analysis.

    Summary Systemic anaplastic large cell lymphomas (sALCLs) comprise a heterogeneous group of relatively rare T-cell non-Hodgkin lymphomas characterized by CD30 expression and other unifying pathologic features. ALK fusions are present in about 50% of cases. Pathological diagnosis can be challenging, particularly in ALK-negative cases. Though ALK-positive and ALK-negative sALCL are similar morphologically and immunophenotypically, they are separate entities with different genetics, clinical behavior, and outcomes. Evidence-based data evaluating treatment regimens are limited as randomized controlled trials are lacking and most prospective studies are too small to draw definitive conclusions. However, recent advances in molecular biology are bringing forth much needed knowledge in this field, and are likely to guide further targeted therapeutic development. PMID:26581318

    Human anaplastic lymphoma kinase (ALK) has become a well-established target for the treatment of ALK-positive non-small cell lung cancer (NSCLC). Here, we have profiled seven small-molecule inhibitors, including 2 that are approved drugs, against a panel of clinically relevant mutations in ALK tyrosine kinase (TK) domain, aiming at a comprehensive understanding of molecular mechanism and biological implication underlying inhibitor response to ALK TK mutation. We find that (i) the gatekeeper mutation L1196M causes crizotinib resistance by simultaneously increasing and decreasing the binding affinities of, respectively, ATP and inhibitor to ALK, whereas the secondary mutation C1156Y, which is located far away from the ATP-binding site of ALK TK domain, causes the resistance by inducing marked allosteric effect on the site, (ii) the 2nd and 3rd generation kinase inhibitors exhibit relatively high sensitivity towards ALK mutants as compared to 1st generation inhibitors, (iii) the pan-kinase inhibitor staurosporine is insensitive for most mutations due to its high structural compatibility, and (iv) ATP affinity to ALK is generally reduced upon most clinically relevant mutations. Furthermore, we also identify six novel mutation-inhibitor pairs that are potentially associated with drug resistance. In addition, the G1202R and C1156Y mutations are expected to generally cause resistance for many existing inhibitors, since they can address significant effect on the geometric shape and physicochemical property of ALK active pocket.

    Cellular immune responses against the oncoantigen anaplastic lymphoma kinase (ALK) in patients with ALK-positive anaplastic large cell lymphoma (ALCL) have been detected using peptide-based approaches in individuals preselected for human leucocyte antigen (HLA)-A*02:01. In this study, we aimed to evaluate nucleophosmin (NPM)-ALK-specific CD8(+) T cell responses in ALCL patients ensuring endogenous peptide processing of ALK antigens and avoiding HLA preselection. We also examined the HLA class I restriction of ALK-specific CD8(+) T cells. Autologous dendritic cells (DCs) transfected with in-vitro-transcribed RNA (IVT-RNA) encoding NPM-ALK were used as antigen-presenting cells for T cell stimulation. Responder T lymphocytes were tested in interferon-gamma enzyme-linked immunospot (ELISPOT) assays with NPM-ALK-transfected autologous DCs as well as CV-1 in Origin with SV40 genes (COS-7) cells co-transfected with genes encoding the patients' HLA class I alleles and with NPM-ALK encoding cDNA to verify responses and define the HLA restrictions of specific T cell responses. NPM-ALK-specific CD8(+) T cell responses were detected in three of five ALK-positive ALCL patients tested between 1 and 13 years after diagnosis. The three patients had also maintained anti-ALK antibody responses. No reactivity was detected in samples from five healthy donors. The NPM-ALK-specific CD8(+) T cell responses were restricted by HLA-C-alleles (C*06:02 and C*12:02) in all three cases. This approach allowed for the detection of NPM-ALK-reactive T cells, irrespective of the individual HLA status, up to 9 years after ALCL diagnosis.

    The discovery by Morris et al. (1994) of the genes contributing to the t(2;5)(p23;q35) translocation has laid the foundation for a molecular based recognition of anaplastic large cell lymphoma and highlighted the need for a further stratification of T-cell neoplasia. Likewise the detection of anaplastic lymphoma kinase (ALK) genetic lesions among many human cancers has defined unique subsets of cancer patients, providing new opportunities for innovative therapeutic interventions. The objective of this review is to appraise the molecular mechanisms driving ALK-mediated transformation, and to maintain the neoplastic phenotype. The understanding of these events will allow the design and implementation of novel tailored strategies for a well-defined subset of cancer patients. PMID:22649787

    Summary Immunohistochemical determination of p63 protein is frequently used in the pathologic diagnosis of nonhematological solid tumors. In malignant hematological disease, p63 expression has been reported in 22% of follicular lymphoma, about 35% of diffuse large B-cell lymphoma, 23% of chronic lymphocytic leukemia, and in some cases of blast crisis of chronic myelogenous leukemia. Anaplastic large cell lymphoma is a rare disease that accounts for less than 5% of all cases of non-Hodgkin's lymphoma. There is little information concerning p63 expression in this specific type of lymphoma. In some cases, the morphological and phenotypic features between anaplastic large cell lymphoma and classical Hodgkin's lymphoma are similar, making this differential diagnosis challenging. We studied p63 expression using a tissue microarray approach in 154 cases of anaplastic large cell lymphoma, including 38% anaplastic large cell kinase positive and 62% anaplastic large cell kinase negative, and 58 Hodgkin's lymphoma cases. Sixty-eight cases of anaplastic large cell lymphoma (44%) showed p63 nuclear positivity (41% of anaplastic large cell kinase positive and 47% of anaplastic large cell kinase negative). Of 130 cases of systemic-anaplastic large cell lymphoma, 42% showed p63 positivity. The neoplastic cells expressed p63 in 38% of the cases of CD45-negative/anaplastic large cell kinase–negative null cell–type anaplastic large cell lymphoma, a subgroup that offers the most difficulties in the differential diagnosis with classical Hodgkin's lymphoma. In contrast, none of the cases of classical Hodgkin's lymphoma demonstrated any p63 expression. These results demonstrate that p63 protein expression is frequently expressed in a subset of anaplastic large cell lymphoma cases and may be used as a potential tool in the differential diagnosis between anaplastic large cell lymphoma and classical Hodgkin's lymphoma.

    This chapter describes a study in which the pattern of numerical chromosomal alterations in cutaneous anaplastic large cell lymphoma (C-ALCL) tumor samples was defined using array-based comparative genomic hybridization (CGH). First, the array-based CGH technique applied is outlined in detail. Next, its application in the analysis of C-ALCL tumor specimens is described. This approach resulted in the identification of highly recurrent chromosomal alterations in C-ALCL that include gain of 7q31 and loss on 6q16-6q21 and 13q34, each affecting 45% of the patients. The pattern characteristic of C-ALCL differs markedly from chromosomal alterations observed in other CTCL such as mycosis fungoides and Sézary syndrome and yielded several candidate genes with potential relevance in the pathogenesis of C-ALCL.

    Classical Hodgkin lymphoma and ALK(-) anaplastic large cell lymphoma share many features like strong CD30 expression and usually loss of B- and T-cell markers. However, their clinical course is dramatically different with curability rates of >90% for classical Hodgkin lymphoma and an unfavorable prognosis for anaplastic large cell lymphoma. Classical Hodgkin lymphoma and ALK(-) anaplastic large cell lymphoma can usually be distinguished by PAX5 expression in the Hodgkin and Reed-Sternberg cells of classical Hodgkin lymphoma and expression of cytotoxic molecules in tumor cells of anaplastic large cell lymphoma. However, in some cases the differential diagnosis is difficult owing to absence of established markers. To be able to better classify these cases, we reevaluated gene expression data of microdissected tumor cells of both lymphomas for differentially expressed genes. A classifier was established, comprising four genes strongly expressed in Hodgkin and Reed-Sternberg cells of classical Hodgkin lymphoma (MDC/CCL22, CD83, STAT3, and TUBB2B). Applying this classifier to a test cohort, Hodgkin lymphoma was successfully distinguished from ALK(-) anaplastic large cell lymphoma with an accuracy of 97% (43/44). MDC/CCL22, CD83, and STAT3 have also been found to be expressed in antigen-presenting cells. Therefore, based on our established classifier, Hodgkin and Reed-Sternberg cells differ from tumor cells of anaplastic large cell lymphoma, which can successfully be applied for practical purposes in histopathologic diagnostics.

    T-cell lymphomas are rare in children. Anaplastic large cell lymphoma (ALCL) is the most common pediatric mature T-cell lymphoma, accounting for about 10-20% of all pediatric non-Hodgkin lymphoma. ALCL is now recognized as two distinct diseases, i.e., ALCL-ALK-positive (ALCL- ALK+) and ALCL-ALK-negative (ALCL- ALK-); ALK-positive ALCL presents at a younger age and has a better prognosis. The human T-cell lymphotropic virus (HTLV-1) is a retrovirus that mainly infects helper T lymphocytes and is linked to the development of adult T-cell leukemia/lymphoma (ATLL). The other type of lymphoma related to this virus family is hairy cell leukemia (HCL). Both of these neoplasms frequently express CD25 (alpha chain-IL-2 receptor). Recently, it was demonstrated that CD25 is significantly expressed in childhood ALCL (75%). In Brazil, HTLV-1 infection is considered endemic, and vertical transmission is responsible for spread to children, and it is important to point out that 90% or more of the HTLV-1 carriers remain asymptomatic. Some cases of HTLV-1-related lymphomas in adults are described as having characteristics of ALCL, but are considered to be CD30-positive subtypes of ATLL based on the virologic findings. No similar cases have been described in children, therefore we analyzed 33 cases of pediatric ALCL, both CD25-positive and CD25-negative, looking for the presence of proviral HTLV-1 DNA, by PCR. All cases corresponded to the common histological type of ALCL and were CD30-positive in virtually all neoplastic cells. ALK expression was observed in all but two cases (93.9%), while CD25 was positive in 27 cases (82%), including one of the ALCL-ALK-. There was a strong positive correlation between ALK and CD25 expression. None of the cases showed proviral HTLV-1-DNA presence. Our study concludes that ALCL in children has no relationship with HTLV-1 and the high frequency of CD25 expression must be explained by a different mechanism than that described in ATLL.

    Anaplastic large cell lymphoma (ALCL) is one of the most common T-cell non-Hodgkin lymphomas and has two main subtypes: an ALK-positive subtype characterized by ALK gene rearrangements and an ALK-negative subtype that is poorly understood. We recently identified recurrent rearrangements of the DUSP22 locus on 6p25.3 in both primary cutaneous and systemic ALK-negative ALCLs. This study aimed to determine the relationship between these rearrangements and expression of the chemokine receptor gene, CCR8. CCR8 has skin-homing properties, and has been suggested to play a role in limiting extracutaneous spread of primary cutaneous ALCLs. However, overexpression of CCR8 also has been reported in systemic ALK-negative ALCLs. As available antibodies for CCR8 have shown lack of specificity, we examined CCR8 expression using quantitative real-time PCR in frozen tissue and RNA in situ hybridization (ISH) in paraffin tissue. Both approaches showed higher CCR8 expression in ALCLs with DUSP22 rearrangements than in non-rearranged cases (PCR: 19.5-fold increase, p=0.01; ISH: 3.3-fold increase, p=0.0008). CCR8 expression was not associated with cutaneous presentation, cutaneous biopsy site, or cutaneous involvement during the disease course. These findings suggest that CCR8 expression in ALCL is more closely related to the presence of DUSP22 rearrangements than to cutaneous involvement, and that the function of CCR8 may extend beyond its skin-homing properties in this disease. This study also underscores the utility of RNA-ISH as a paraffin-based method for investigating gene expression when reliable antibodies for immunohistochemistry are not available. PMID:25390351

    Primary cutaneous CD 30 (+) anaplastic large cell lymphoma (PCALCL) is a rare and indolent type of cutaneous T cell lymphoma, which usually presents as an asymptomatic solitary firm nodule that rapidly grows and often ulcerates without any systemic involvement. A 64-year-old female presented to our outpatient clinic with a one-year history of multiple pink nodular lesions on the chest, back and gluteal regions. Dermoscopic examination of the nodular lesions revealed pink-to-yellow structureless areas and arborizing-to-polymorphous vessels. Histopathologic examination was consistent with CD30 (+) anaplastic large cell lymphoma. Systemic involvement was not detected. Local radiotherapy for large nodules and surgical excision for small nodules were performed. The large nodules had totally regressed after 10 sessions of radiotherapy. PMID:28243498

    Primary cutaneous anaplastic large cell lymphoma (pcALCL) forms 9% of the cutaneous T-cell lymphomas. It usually presents as solitary reddish brown ulcerating nodule or indurated plaque. Sometimes, it mimics other dermatological diseases such as eczema, pyoderma gangrenosum, pyogenic granuloma, morphea, and squamous cell carcinoma. Our case presented with large pyogenic granuloma like lesion with regional lymphadenopathy. Since pcALCL is rare, one can misdiagnose such cases and therefore high index of suspicion is necessary.

    Introduction Anaplastic large cell lymphoma is a very rare T-cell lymphoma that has only recently been found to be associated with breast implants. It has been described in the literature mainly in the form of case reports. This article focuses on the imaging characteristics of this rare disease. We hope to increase awareness of breast imagers and referring physicians to improve early detection rates. Case Report We present the case of a 32-year-old female who presented with several weeks of pain and firmness in her right breast. MRI and ultrasound demonstrated a peri-implant fluid collection. Ultrasound-guided aspiration revealed anaplastic large cell lymphoma. The patient was treated with implant removal alone and has now been in remission for 3 years.  Conclusion Anaplastic large cell lymphoma of the breast is a very rare entity that has mainly been described in the literature as case reports. As in the case of our patient, imaging findings can be very non-specific, and it is important for surgeons, breast imagers, and oncologists to be aware of this rare disease to ensure prompt diagnosis.

  7. Epigenetic silencing of the proapoptotic gene BIM in anaplastic large cell lymphoma through an MeCP2/SIN3a deacetylating complex.

    BIM is a proapoptotic member of the Bcl-2 family. Here, we investigated the epigenetic status of the BIM locus in NPM/ALK+ anaplastic large cell lymphoma (ALCL) cell lines and in lymph node biopsies from NPM/ALK+ ALCL patients. We show that BIM is epigenetically silenced in cell lines and lymph node specimens and that treatment with the deacetylase inhibitor trichostatin A restores the histone acetylation, strongly upregulates BIM expression, and induces cell death. BIM silencing occurs through recruitment of MeCP2 and the SIN3a/histone deacetylase 1/2 (HDAC1/2) corepressor complex. This event requires BIM CpG methylation/demethylation with 5-azacytidine that leads to detachment of the MeCP2 corepressor complex and reacetylation of the histone tails. Treatment with the ALK inhibitor PF2341066 or with an inducible shRNA targeting NPM/ALK does not restore BIM locus reacetylation; however, enforced expression of NPM/ALK in an NPM/ALK-negative cell line significantly increases the methylation at the BIM locus. This study demonstrates that BIM is epigenetically silenced in NPM/ALK-positive cells through recruitment of the SIN3a/HDAC1/2 corepressor complex and that NPM/ALK is dispensable to maintain BIM epigenetic silencing but is able to act as an inducer of BIM methylation.

    Hemophagocytic lymphohistiocytosis (HLH) has a well known association with lymphomas, especially of T cell origin. Prognosis of lymphoma associated HLH is very poor, especially in T cell lymphomas; and, therefore, early diagnosis might alter the outcome. Though association of HLH with systemic anaplastic large cell lymphoma (ALCL) is known, its occurrence in primary cutaneous ALCL (C-ALCL) is distinctly rare. We aim to describe a case of C-ALCL (anaplastic lymphoma kinase (ALK)−) in an elderly male who succumbed to the complication of associated HLH, which was possibly triggered by coexistent virus infection. We briefly present the literatures on lymphoma associated HLH and discuss the histopathological differentials of cutaneous CD30+ lymphoproliferative disorders. We do suggest that HLH may pose diagnostic challenges in the evaluation of an underlying lymphoma and hence warrants proper evaluation for the underlying etiologies and/or triggering factors.

    We present case of Anaplastic Large Cell Lymphoma discovered as an incidental finding whilst revising an implant based breast reconstruction in a 55 year old woman, whom previously had undergone risk reduction mastectomies and immediate reconstruction. During the procedure a presumed seroma was present but this was macroscopically atypical giving a 'milky' coloured appearance with a pink tinge to it. The atypical fluid was sent for analysis and the diagnosis of ALCL confirmed. Treatment consisted of unilateral capsulectomy on the affected side and bilateral removal of implants with staging scans suggesting the disease being confined to the capsule. She remains in remission 12 months following the original procedure.

    Breast implant associated anaplastic large cell lymphoma (BIALCL) is a distinct clinical entity that can present in patients receiving either reconstructive or cosmetic breast implants. Presenting symptoms include onset of a delayed (>1 year after implantation) fluid collection, mass of the capsule, or lymphadenopathy. Treatment has progressed in recent years and most commonly includes implant removal and total resection of the tumor, including capsule, mass, and involved lymph nodes. Further research is warranted to determine potential malignant drivers, disease progression, and optimal treatment strategies in advanced disease.

    Primary breast anaplastic large cell lymphoma (ALCL) is rare but is more commonly seen in patients with implants; fewer than 50 cases of breast implant-associated ALCL have been reported in the English language literature. Breast implant-associated ALCL is not a disease of the breast parenchyma, but instead is a disease of the fibrous capsule surrounding the implant. The patients usually present with an effusion around the implant and, rarely, with a solid mass. Morphologically, the neoplastic cells are large, epithelioid, and pleomorphic, with abundant cytoplasm, vesicular irregular nuclei, and frequent mitoses. Occasional "hallmark" cells may be present. The lesional cells typically show strong and diffuse immunoreactivity for CD30 and often express T-cell markers, cytotoxic-associated antigens, and epithelial membrane antigen. Almost all reported cases are negative for anaplastic lymphoma kinase. Molecular genetic analyses have demonstrated T-cell receptor gene rearrangements. The differential diagnosis essentially includes poorly differentiated carcinoma, other lymphomas, and chronic inflammation. Once a diagnosis of lymphoma is established, it is important to exclude systemic anaplastic lymphoma kinase-negative ALCL involving the breast, primary cutaneous ALCL, and other CD30(+) lymphoproliferative disorders. The patients with effusion-associated ALCL often have an indolent course and excellent prognosis, responding well to excision of the fibrous capsule around the implant (capsulectomy) and implant removal. In contrast, patients who present with a distinct mass may have a more aggressive course and poor prognosis, requiring chemotherapy and/or radiation therapy.

    The anaplastic large cell lymphoma is a rare entity in pediatric patients. We present an unusual case of pericardial involvement, quite uncommon as extranodal presentation of this type of disorder, that provoked a life-risk situation requiring an urgent pericardiocentesis. To our knowledge, this is the first report on a child with pericardial involvement without an associated cardiac mass secondary to anaplastic large cell lymphoma in pediatric age. We report the case of a 21-month-old Caucasian male infant with cardiac tamponade associated with the presentation of anaplastic large cell lymphoma. Initially, the child presented with 24-day prolonged fever syndrome, cutaneous lesions associated with hepatomegaly, inguinal adenopathies, and pneumonia. After a 21-day asymptomatic period, polypnea and tachycardia were detected in a clinical check-up. Chest X-ray revealed a remarkable increase of the cardiothoracic index. The anaplastic large cell lymphoma has a high incidence of extranodal involvement but myocardial or pericardial involvements are rare. For this reason, we recommend a close monitoring of patients with a differential diagnosis of anaplastic large cell lymphoma. PMID:26435869

    Although Anaplastic Large Cell Lymphomas (ALCL) carrying Anaplastic Lymphoma Kinase (ALK) have a relatively good prognosis, aggressive forms exist. We have identified a novel translocation, causing the fusion of the TRAF1 and ALK genes, in one patient who presented with a leukemic ALK+ ALCL (ALCL-11). To uncover the mechanisms leading to high-grade ALCL, we developed a human Patient Derived Tumorgraft (hPDT) line. Molecular characterization of primary and PDT cells demonstrated the activation of ALK and of NFkB pathways. Genomic studies of ALCL-11 showed the TP53 loss and the in vivo subclonal expansion of lymphoma cells lacking PRDM1/Blimp-1 and with c-MYC gene amplification. The treatment with proteasome inhibitors of TRAF1-ALK cells led to down-regulation of p50/p52 and lymphoma growth inhibition. Moreover a NFkB gene set classifier stratified ALCL in distinct subsets with different clinical outcome. Moreover, a selective ALK inhibitor (CEP28122) resulted in a significant clinical response of hPDT mice, but the disease could not be eradicated. These data indicate that the activation of NFkB signaling contributes to the neoplastic phenotype of TRAF1-ALK ALCL. ALCL hPDTs are invaluable to validate the role of druggable molecules, predict therapeutic responses and are helpful tools for the implementation of patient specific therapies. PMID:25533804

    Primary central nervous system lymphoma (PCNSL) is usually diffuse large B-cell lymphoma. Anaplastic large-cell lymphoma (ALCL) rarely occurs in the central nervous system. PCNSL always presents as single or multiple nodular contrast-enhancing mass lesions within T2-hyperintense areas on magnetic resonance imaging (MRI). Infrequently, diffuse infiltrating change with little contrast enhancement called lymphomatosis cerebri can be seen in PCNSL. In this report, we describe a 75-year-old immunocompetent man who had progressive dementia. On MRI, diffuse white matter lesions with little contrast enhancement were observed to gradually progress, which was clinically consistent with his worsening condition. A biopsy specimen revealed non-destructive, diffusely infiltrating, anaplastic large CD30-positive lymphoma, indicating a diagnosis of ALCL. After the biopsy, he was treated by whole brain irradiation (total 46 Gy) and focal boost irradiation (total 14 Gy). However, his performance status worsened and there was no symptom improvement. The patient died 8 months after symptom onset. The clinical course, diagnostic workup, pathologic correlates, and treatment outcomes are described herein.

    Breast implant-associated anaplastic large cell lymphoma (ALCL) is a newly described clinical and pathologic entity that typically presents as seroma in the fibrous scar around the implant. Less frequently, it presents as a solid peri-implant mass, and there have been no reports to date of cutaneous lesions as the presenting manifestation. We report the case of a 56-year-old woman with a history of bilateral breast reconstruction following breast cancer of the right breast who consulted with several papules on the right breast suggestive of metastasis. Histopathology showed a proliferation of large epithelioid lymphocytes with highly pleomorphic cells and nuclei. The neoplastic cells were CD15 and CD30 positive and ALK-1 negative. The epithelial markers were all negative except for epithelial membrane antigen (EMA), which was weakly positive. Molecular analysis showed monoclonal T-cell receptor γ gene rearrangement, confirming a diagnosis of breast implant-associated ALCL. The non-specific morphology of the skin lesions, the epithelioid nature of the neoplastic cells and the expression of EMA can lead to an erroneous diagnosis of skin metastases from a poorly differentiated adenocarcinoma of the breast. We recommend immunohistochemical staining for CD30 and ALK-1 for patients with breast implants who develop anaplastic lesions.

    Implant-associated anaplastic large cell lymphoma (ALCL) is the subject of much debate in the field of plastic surgery. Only a few published cases have been reported and the rarity of the disease may make proving causality exceedingly difficult. Despite this, it is of utmost importance that full attention be devoted to this subject to ensure the safety and well-being of patients. The authors report one new case of implant-associated ALCL that recently presented to their institution. Implant-associated ALCL is a poorly understood disease. It should likely be considered its own clinical entity and categorized into two subtypes: one presenting as a seroma and the other as a distinct mass or masses. When reported, only textured implants have been associated with ALCL. The United States Food and Drug Administration and American Society of Plastic Surgeons have initiated a registry and have collected critical data to gain further understanding of this disease.

    Despite the relative success of chemotherapy for Hodgkin lymphoma (HL) and systemic anaplastic large cell lymphoma (ALCL), novel therapeutic agents are needed for refractory or relapsed patients. Targeted immunotherapy has emerged as a novel treatment option for these patients. Although unconjugated anti-cluster of differentiation (CD)30 antibodies showed minimal antitumor activity in early clinical trials, development of antibody–drug conjugates (ADCs) appears promising. Brentuximab vedotin is an ADC composed of an anti-CD30 antibody linked to a potent microtubule-disrupting agent monomethyl auristatin E (MMAE). It has the ability to target CD30-positive tumor cells and, once bound to CD30, brentuximab vedotin is internalized and MMAE is released to induce cell cycle arrest and apoptosis. In two Phase II trials, objective response was reported in 75% and 86% of patients with refractory or relapsed HL and systemic ALCL, respectively, with an acceptable toxicity profile. Based on these studies, the US Food and Drug Administration (FDA) granted accelerated approval of brentuximab vedotin in August 2011 for the treatment of refractory and relapsed HL and ALCL. We review the key characteristics of brentuximab vedotin, clinical data supporting its therapeutic efficacy, and current ongoing trials to explore its utility in other CD30-positive malignancies.

    The safety of silicone-based implant for mammoplasty has been debated for decades. A series of anecdotal case reports and a recent epidemiological case-control study have suggested a possible association between silicone implant and the development of primary breast ALK1-negative anaplastic large cell lymphoma (ALCL), a rare type of peripheral T-cell lymphoma. In this report, we describe an additional case of primary breast ALK1-negative ALCL in the fibrous capsule and cystic fluid of silicone breast implant in a 58 year old woman who underwent breast reconstructive surgery after lumpectomy for her infiltrating breast adenocarcinoma. Morphologically and immunohistochemically, the lymphoma cells may be confused with recurrent infiltrating breast adenocarcinoma or other non-hematolymphoid malignancies. Molecular studies were needed to determine T-lineage differentiation of the malignant lymphoma cells. We will also review the case reports and case series published in the English literature and discuss our current understanding of silicone implant in primary breast ALK1-negative ALCL. PMID:19918336

    Breast implant-associated anaplastic large cell lymphoma (ALCL) is a rare T-cell lymphoma arising around breast implants. Public awareness has increased following a safety communication warning of the association of breast implant-associated ALCL by the U.S. Food and Drug Administration in 2011. Difficulty with determining an accurate assessment of risk, including diagnosis, or standardized treatment regimen has led surgeons to commonly omit preoperative discussion of this rare and frequently misunderstood cancer. Risk disclosure is a form of respect for patient autonomy, and informed consent has positive practical and moral consequences for the practice of plastic surgery. A model of breast implant-associated ALCL informed consent implementation and health care provider education are reviewed with 1-year process follow-up at a tertiary cancer center. Breast implant-associated ALCL should be included during preoperative counseling on the risks of breast implantation when obtaining informed consent. Pertinent aspects of decision-making include disease awareness, presenting symptoms, and resources for concerned patients. Education of health care professionals and provision of patient-focused materials ensures effectiveness of the informed consent process.

    In the last two decades posttransplant lymphoproliferative disorders (PTLDs) have been recognized as a complication of organ transplantation with immunosuppression. The reported incidence of PTLDs in renal transplant patients ranges between 0.3-3% (Birkeland et al., Transplantation 1999;67:876-881). In contrast to the reported incidence of PTLDs in post bone marrow transplant, it is 1% in HLA-matched recipients and up to 20% in HLA mismatched T-cell depleted bone marrow recipients (Curtis et al., Blood 1996;94:2208-2216). In cardiac transplant recipients the reported incidence of PTLDs is between 1.8-9.8 (Mihalov et al., Clin Transplant 1996;10:248-255). PTLDs are predominately extranodal. They have varied morphologic patterns and clonality, but almost all are associated with Epstein-Barr virus (EBV). The vast majority are of B cell lineage; only about 10% are of T-cell origin. We report a T-cell anaplastic large cell lymphoma (ALCL) presenting with bilateral pleural effusion and liver involvement in a renal transplant recipient.

    The discovery of anaplastic lymphoma kinase (ALK) gene rearrangements and the development of tyrosine kinase inhibitors (TKI) that target them have achieved unprecedented success in the management of patients with ALK-positive non-small cell lung cancer (NSCLC). Despite the high efficacy of crizotinib, the first oral ALK TKI approved for the treatment of ALK-positive NSCLC, almost all patients inevitably develop acquired resistance, showing disease progression in the brain or in other parenchymal sites. Second- or third-generation ALK TKIs have shown to be active in crizotinib-pretreated or crizotinib-naïve ALK-positive patients, even in those with brain metastases. In this review, the current knowledge regarding ALK-positive NSCLC, focusing on the biology of the disease and the available therapeutic options are discussed. PMID:27799783

    Purpose: Primary cutaneous CD30+ anaplastic large-cell lymphoma (CALCL) is a relatively rare and indolent variant of cutaneous T-cell lymphoma (CTCL). This report examines the response of localized disease to radiation alone. Methods: The Yale Cancer Center records were examined, and all patients with CTCL from January 1, 2001, to September 1, 2006, evaluated in the Department of Therapeutic Radiology were identified. Only those patients with localized or single CALCL lesions, no clinical evidence or history of lymphomatoid papulosis, no history of other CTCLs, no history of other skin disorders, lack of lymph node involvement, unambiguous pathology reports, and treatment with radiation alone were included. Results: Eight patients were identified. Median age was 67 years, and gender was split evenly. Patients received radiation ranging from 34 to 44 Gy in 2-Gy fractions. Most patients (5 of 8) received 40 Gy, using 6 to 9 MeV electrons with 0.5 to 2 cm of bolus. All patients had a complete response. All patients were without evidence of disease at the most recent follow-up (median follow-up, 12 months). Radiation therapy was well tolerated, and the only recorded toxicity was Grade I to II dermatitis. Conclusions: Radiation therapy alone for localized CALCL is very well tolerated and clinical response is excellent. A dose of 40 Gy in 2-Gy fractions seems to be well tolerated and effective in inducing a complete response. Lower doses may be effective in achieving the same result, but data are not available. Longer follow-up is necessary before conclusions regarding durable disease-free survival can be made.

    We report 13 cases of anaplastic large cell lymphoma (ALCL) associated with breast implants. Patient age ranged from 39 to 68 years, and the interval from implant to ALCL was 4 to 29 years. All tumors were composed of large, pleomorphic cells that were CD30 and ALK1, and all 7 cases assessed had monoclonal T-cell receptor γ-chain rearrangements. Two patient subgroups were identified. Ten patients presented with effusion surrounded by fibrous capsule without a grossly identifiable tumor mass. Nine patients had stage I and 1 had stage II disease. Eight patients underwent implant removal and capsulectomy. Four patients received chemotherapy and 4 radiation therapy. All patients were alive without disease at last follow-up. A second subgroup of 3 patients had effusion and a distinct mass adjacent to the implant. One patient had stage I and 2 stage II disease. One patient had a 3-year history of lymphomatoid papulosis, and 1 patient had a 1-year history of CD30 T-cell lymphoma adjacent to the breast before the diagnosis of ALCL associated with breast implant. Two patients received chemotherapy and 1 radiation therapy. Two patients died 2 and 12 years after diagnosis, respectively. We conclude that the clinical behavior of ALCL associated with breast implants is heterogeneous. Patients who present with effusion without a distinct mass have an indolent disease course, similar to CD30 lymphoproliferative disorder of skin. In contrast, patients who present with a distinct mass may have advanced stage or possibly systemic disease and have a poorer prognosis.

    The expression of myelomonocytic-associated antigens in anaplastic large cell lymphomas (ALCLs), particularly those presenting in extranodal sites, can make their distinction from extramedullary myeloid cell tumors (EMCTs) or histiocytic tumors problematic. Yet, this distinction is clinically significant because of its therapeutic and prognostic implications. Herein, we describe a case of extranodal anaplastic lymphoma kinase-positive CD30-positive ALCL of T-cell origin in a 12-year-old boy, which was initially called an EMCT because of the expression of CD13 and HLA-DR detected by flow cytometry and the absence of other T-cell-related surface markers. However, the detection of cytoplasmic CD3 by flow cytometry prompted further studies. The tumor was composed of large cells with abundant slightly eosinophilic vacuolated cytoplasm and ovoid or reniform nuclei with a few small nucleoli. Using immunohistochemistry, the tumor was positive for CD45, CD30, CD45RO, and CD43 with a strong cytoplasmic and nuclear anaplastic lymphoma kinase stain. The tumor cells showed a T-cell clonal genotype. Electron microscopy revealed no ultrastructural features of myelomonocytic or histiocytic origin. The patient responded well to the chemotherapy and was in complete remission for 10 months at the time of submission of this manuscript. Review of the literature showed inconsistencies regarding the diagnosis, nomenclature, and, therefore, treatment and prognosis of these tumors. In addition, the CD13 expression in ALCL raises some histogenetic questions and may indicate origin from a pluripotent stem cell, misprogramming during malignant transformation, or a microenvironmental effect on lymphoid cell expression of surface antigens. Therefore, ALCL should be considered in the differential diagnosis of EMCTs or histiocytic tumors, particularly when surface marker lineage assignment is ambiguous.

Case 1 was a 39-year-old man who developed multiple tumors in the mediastinum, psoas muscle, lung, and lymph nodes. A biopsy specimen of the inguinal node was effaced by large tumor cells expressing CD30, epithelial membrane antigen, and cytoplasmic ALK, which led to a diagnosis of ALK(+) ALCL. Case 2 was a 51-year-old man who was initially diagnosed with undifferentiated carcinoma. He developed multiple skin tumors eight years after his initial presentation, and was finally diagnosed with ALK(+) ALCL. He died of therapy-related acute myeloid leukemia. G-banding and fluorescence in situ hybridization using an ALK break-apart probe revealed the rearrangement of ALK and suggested variant translocation in both cases. We applied an inverse cDNA polymerase chain reaction (PCR) strategy to identify the partner of ALK. Nucleotide sequencing of the PCR products and a database search revealed that the sequences of ATIC in case 1 and TRAF1 in case 2 appeared to follow those of ALK. We subsequently confirmed ATIC-ALK and TRAF1-ALK fusions by reverse transcriptase PCR and nucleotide sequencing. We successfully determined the partner gene of ALK in two cases of ALK(+) ALCL. ATIC is the second most common partner of variant ALK rearrangements, while the TRAF1-ALK fusion gene was first reported in 2013, and this is the second reported case of ALK(+) ALCL carrying TRAF1-ALK.

    Neutrophil-rich CD30+ anaplastic large-cell lymphoma (ALCL) is a rare pathological entity without distinct clinical behavior. Twelve cases of neutrophil-rich CD30+ anaplastic large-cell lymphoma (ALCL) have been reported, three of them were HIV-infected patients. All these reports stressed the presence of neutrophil infiltration as a new morphologic feature of CD30+ ALCL. Only one case of cutaneous involvement presented with microabscess formation. We describe a case of neutrophil-rich CD30+ ALCL in an AIDS patient with a clinical picture determined by the massive neutrophil infiltration of the tumor without necrosis nor local infection, but with the formation of abscesses.

    A large subset of anaplastic large cell lymphoma (ALCL) patients harbour a somatic aberration in which anaplastic lymphoma kinase (ALK) is fused to nucleophosmin (NPM) resulting in a constitutively active signalling fusion protein, NPM-ALK. We computationally simulated the signalling network which mediates pathological cell survival and proliferation through NPM-ALK to identify therapeutically targetable nodes through which it may be possible to regain control of the tumourigenic process. The simulations reveal the predominant role of the VAV1-CDC42 (cell division control protein 42) pathway in NPM-ALK-driven cellular proliferation and of the Ras / mitogen-activated ERK kinase (MEK) / extracellular signal-regulated kinase (ERK) cascade in controlling cell survival. Our results also highlight the importance of a group of interleukins together with the Janus kinase 3 (JAK3) / signal transducer and activator of transcription 3 (STAT3) signalling in the development of NPM-ALK derived ALCL. Depending on the activity of JAK3 and STAT3, the system may also be sensitive to activation of protein tyrosine phosphatase-1 (SHP1), which has an inhibitory effect on cell survival and proliferation. The identification of signalling pathways active in tumourigenic processes is of fundamental importance for effective therapies. The prediction of alternative pathways that circumvent classical therapeutic targets opens the way to preventive approaches for countering the emergence of cancer resistance. PMID:27669408

    Although primary breast lymphomas are exceedingly rare, cases of breast implant-associated anaplastic large cell lymphoma (iALCL) continue to be reported. The authors describe their experience with 2 patients and review the literature. Both patients presented with periprosthetic fluid collection. Neither had evidence of systemic disease nor received systemic therapy. Both were disease free after bilateral capsulectomies and implant removal without implant replacement, and disease did not recur. During the literature review, 63 cases of iALCL (including our 2 patients) were identified. The median time from implant placement to diagnosis was 9 years. Both saline and silicone implants were associated with iALCL. Of the 26 cases for which implant surface was reported, the surface was textured in 24. Of the 58 patients with an identifiable presentation, 39 had periprosthetic fluid collection, including 7 with an associated mass; 13 had an isolated mass at presentation, including 1 with axillary adenopathy. Forty patients had capsulectomy, 7 of whom underwent implant replacement. Of the 44 patients with known treatment, 33 received chemotherapy and 23 received radiation. Of the 49 patients with known anaplastic large cell lymphoma, 15 had disease recurrence, and 4 patient deaths were reported. Of the 18 patients presenting with a mass, 11 had disease recurrence, including all 4 patients who died. This study represents the largest review of patients with iALCL described to date. Although most cases have an indolent clinical course, the variety of presentations defined as "seroma" vs "capsular involvement" emphasizes the importance of investigating a definitive method of diagnosis, management, and treatment of this disease.

    To evaluate haematopoietic stem cell transplantation (HSCT) in children and adolescents, we reviewed the records of 47 patients who were ≤18 years, had relapsed or refractory anaplastic large cell lymphoma, and received HSCT between 1990 and 2010. At HSCT, complete remission (CR) was less common in allogeneic HSCT recipients (n = 24) than in autologous HSCT recipients (n = 23) (P = 0·01). The autologous and allogeneic HSCT groups differed in terms of 5-year event-free survival (EFS) (38% vs. 50%, P = 0·63), cumulative incidence of progress or relapse (49% vs. 28%, P = 0·25), and treatment-related mortality (12% vs. 25%, P = 0·40). However, these differences were not significant. Patients with non-CR at autologous HSCT had a significantly lower EFS rate (14% vs. 48%, P = 0·03). Conversely, although those with non-CR at allogeneic HSCT had a lower EFS rate, this was not significant (44% vs. 63%, P = 0·26). Reduced-intensity conditioning regimens were used for three of the 16 allogeneic HSCTs received by patients with non-CR. These three patients achieved CR, surviving 32-65 months after HSCT. These results demonstrated that allogeneic HSCT might be a treatment option for patients who do not achieve CR through conventional chemotherapy.

    CCR3 is a specific marker of anaplastic large cell lymphoma (ALCL) cells. ALCL cells also express CCL11, a ligand for CCR3, leading to the hypothesis that CCL11 may play an autocrine role in ALCL progression. In this study, we investigated a role of CCL11 in cell survival and growth of human Ki-JK cells, established from an ALCL patient, and murine EL-4 lymphoma cells. Both Ki-JK and EL-4 cells expressed cell surface CCR3. CCL11 increased cell survival rates of Ki-JK cells in a dose-dependent manner, whereas it promoted EL-4 cell proliferation. Furthermore, CCL11 induced phosphorylation of extracellular signal-regulated kinase (ERK) 1/2 in both Ki-JK cells and EL-4 cells. Cell survival and tumor proliferation promoted by CCL11 was completely blocked by inhibition of ERK phosphorylation. CCL11 induced expression of antiapoptotic proteins, Bcl-xL and survivin, in Ki-JK cells. CCL11 also enhanced tumor growth of EL-4 and Ki-JK cells in vivo. Consistent with these results, tumor cells of cutaneous ALCL expressed CCR3 and increased levels of phosphorylated ERK1/2, Bcl-xL, and survivin in situ. Thus, our findings prompt a novel therapeutic approach to treat relapses of an aggressive form of lymphoma based on the discovery that a cell surface marker of disease functions as a critical autocrine growth receptor.

    Anaplastic large-cell lymphoma (ALCL) is a rare type of highly malignant, non-Hodgkin lymphoma (NHL). Currently, only studies on the chimeric oncogene NPM-ALK have reported a link to ALCL progression. However, the specific molecular mechanisms underlying the invasion of ALCL are still unclear. Here, we sought to investigate differentially expressed, long non-coding RNAs (lncRNAs) in ALCL and their potential biological function. Our microarray analyses revealed that LINC01013, a novel non-coding RNA gene, was highly expressed in clinical specimens of ALCL and was significantly upregulated in invasive ALCL cell lines. Knockdown of LINC01013 suppressed tumor cell invasion; conversely, its overexpression enhanced tumor cell invasion. LINC01013-induced invasion was mediated by activation of the epithelial-to-mesenchymal transition (EMT)-associated proteins, snail and fibronectin. Specifically, LINC01013 induced snail, resulting in activation of fibronectin and enhanced ALCL cell invasion. Collectively, these findings support a potential role for LINC01013 in cancer cell invasion through the snail-fibronectin activation cascade and suggest that LINC01013 could potentially be utilized as a metastasis marker in ALCL.

    Anaplastic large cell lymphoma is an aggressive T-cell neoplasm. It rarely involves the urinary bladder, with just twelve cases reported thus far and only one being ALK-negative. Immunophenotyping (particularly for ALK) is mandatory, both for prognostic and therapeutic reasons. Herein, we report the case of a patient with an ALK-negative anaplastic large cell lymphoma involving the bladder which was diagnosed and fully characterized by immunocytochemistry in urine cytology. The patient underwent a cystoscopy and the urine sample disclosed tumor diathesis background and aggregates of atypical cells, with evidence of multinucleation and mitotic figures. Immunocytochemistry revealed strong membrane/Golgi positivity for CD30 and negativity for ALK. The patient was submitted to transurethral resection for therapeutic purposes, which confirmed the diagnosis. To the best of our knowledge, this represents only the third case of anaplastic large cell lymphoma with bladder involvement diagnosed in urine cytology and the very first with diagnostic findings allowing for immunophenotyping of the disease in a bladder wash. The present report reinforces the role of urine cytology as a suitable method for establishing an earlier diagnosis and characterization of the disease, avoiding submitting patients to invasive procedures like transurethral resections.

    Posttransplant lymphoproliferative disorder is a relatively common posttransplant malignancy affecting as many as 10% of all solid-organ recipients. Most cases of posttransplant lymphoproliferative disorder are of B-cell origin, with common Epstein-Barr virus association. Posttransplant lymphoproliferative disorders of T-cell origin are much rarer and less frequently associated with Epstein-Barr virus. Here, we report an unusual case of Epstein-Barr virus-positive anaplastic large-cell lymphoma causing an intestinal perforation in an adult renal transplant recipient. A 52-year-old male patient with renal allograft developed cryptogenic end-stage liver failure and was accepted as a candidate for liver transplant. Before transplant, he was admitted with severe abdominal pain, which turned out to result from ileal perforation. Pathologic evaluation of the intestinal resection showed diffuse malignant lymphoid infiltration of the ileum, consistent with anaplastic large-cell lymphoma. The tumor was positive for Epstein-Barr virus genome. Anaplastic large-cell lymphoma is a rare form of T-cell posttransplant lymphoproliferative disorder that is infrequently associated with Epstein-Barr virus. The occurrence of this extraordinary form of post transplant lymphoproliferative disorder, its late onset, intestinal localization, and Epstein-Barr virus as sociation represent a unique clinical rarity.

    Breast implant associated anaplastic large cell lymphoma (BIA-ALCL) is a recently recognized clinical entity, with only 39 well-documented cases reported worldwide, including 3 fatalities. Because of its rarity, the clinical and pathologic features of this malignancy have yet to be fully defined. Moreover, the pathogenesis of ALCL in association with textured silicone gel breast implants is poorly understood. Here we report a case of BIA-ALCL arising in a 67-year-old woman with a mastectomy due to breast cancer followed by implantation of textured silicone gel breast prosthesis. The patient presented with breast enlargement and tenderness 8 years following reconstructive surgery. MRI revealed a fluid collection surrounding the affected breast implant. Pathologic examination confirmed the presence of malignant ALCL T cells that were CD30+, CD8+, CD15+, HLA-DR+, CD25+ ALK- and p53. A diagnosis of indolent BIA-ALCL was made since tumor cells were not found outside of the capsule. Interestingly, an extensive mixed lymphocytic infiltrate and ectopic lymphoid tissue (lymphoid neogenesis) adjacent to the fibrous implant capsule were present. The patient was treated with capsulectomy and implantation of new breast prostheses. Six months later, the patient was found to have BIA-ALCL involvement of an axillary lymph node with cytogenetic evolution of the tumor. To our knowledge, this is the sixth reported case of aggressive BIA-ALCL. Unique features of this case include the association with lymphoid neogenesis and the in vivo cytogenetic progression of the tumor. This case provides insight into the potential role of chronic inflammation and genetic instability in the pathogenesis of BIA-ALCL.

    Anaplastic large-cell lymphoma (ALCL) is a rare and newly described complication associated with breast implants. Patients often present with a peri-implant effusion, which is amenable to fine-needle aspiration. The laboratory handling of peri-implant effusions for cytology and ancillary studies is as crucial as recognizing the characteristic cytology of ALCL. All cases of peri-implant effusions were retrieved from the PathWest database between January 2003 and May 2013, yielding four cases of breast implant-associated ALCL and six benign samples. The cytological features were evaluated and information from ancillary studies collated. Clinical and follow-up histology was available in all cases. All ALCL cases contained highly atypical lymphoid cells including 'hallmark' cells. In contrast, benign peri-implant effusions showed a mixture of inflammatory cells, being either neutrophil-rich (three cases) or lymphocyte-rich (three cases). A CD30 positive, ALK1 negative immunophenotype was demonstrated in all cases on cell block immunohistochemistry. Flow cytometry and T-cell receptor clonality studies confirmed aberrant T-cell immunophenotype in four of four and clonally rearranged T-cell receptor antigens in three of three cases. ALCL was identified in three of four subsequent capsulectomies. Staging confirmed disease limited to the capsular tissue or peri-implant effusion in all cases. None of the six patients with benign peri-implant effusions developed lymphoma during follow-up. Cases of ALCL accounted for 40% of peri-implant effusions received over a 10-year period, indicating the rarity of these samples and the high likelihood of malignancy. Awareness of this entity and its presentation should allow for appropriate triage of these specimens and definitive diagnosis on effusion specimens.

    Purpose Breast implant–associated anaplastic large-cell lymphoma (ALCL) is a recently described clinicopathologic entity that usually presents as an effusion-associated fibrous capsule surrounding an implant. Less frequently, it presents as a mass. The natural history of this disease and long-term outcomes are unknown. Patients and Methods We reviewed the literature for all published cases of breast implant–associated ALCL from 1997 to December 2012 and contacted corresponding authors to update clinical follow-up. Results The median overall survival (OS) for 60 patients was 12 years (median follow-up, 2 years; range, 0-14 years). Capsulectomy and implant removal was performed on 56 of 60 patients (93%). Therapeutic data were available for 55 patients: 39 patients (78%) received systemic chemotherapy, and of the 16 patients (28%) who did not receive chemotherapy, 12 patients opted for watchful waiting and four patients received radiation therapy alone. Thirty-nine (93%) of 42 patients with disease confined by the fibrous capsule achieved complete remission, compared with complete remission in 13 (72%) of 18 patients with a tumor mass. Patients with a breast mass had worse OS and progression-free survival (PFS; P = .052 and P = .03, respectively). The OS or PFS were similar between patients who received and did not receive chemotherapy (P = .44 and P = .28, respectively). Conclusion Most patients with breast implant–associated ALCL who had disease confined within the fibrous capsule achieved complete remission. Proper management for these patients may be limited to capsulectomy and implant removal. Patients who present with a mass have a more aggressive clinical course that may be fatal, justifying cytotoxic chemotherapy in addition to removal of implants. PMID:24323027

    Apart from its unique histopathological appearance with rare tumor cells embedded in an inflammatory background of bystander cells, classical Hodgkin lymphoma (cHL) is characterized by an unusual activation of a broad range of signaling pathways involved in cellular activation. This includes constitutive high-level activity of nuclear factor-κB (NF-κB), Janus kinase/signal transducer and activator of transcription (JAK/STAT), activator protein-1 (AP-1) and interferon regulatory factor (IRF) transcription factors (TFs) that are physiologically only transiently activated. Here, we demonstrate that inactivation of the putative ubiquitin E3-ligase PDLIM2 contributes to this TF activation. PDLIM2 expression is lost at the mRNA and protein levels in the majority of cHL cell lines and Hodgkin and Reed–Sternberg (HRS) cells of nearly all cHL primary samples. This loss is associated with PDLIM2 genomic alterations, promoter methylation and altered splicing. Reconstitution of PDLIM2 in HRS cell lines inhibits proliferation, blocks NF-κB transcriptional activity and contributes to cHL-specific gene expression. In non-Hodgkin B-cell lines, small interfering RNA-mediated PDLIM2 knockdown results in superactivation of TFs NF-κB and AP-1 following phorbol 12-myristate 13-acetate (PMA) stimulation. Furthermore, expression of PDLIM2 is lost in anaplastic large cell lymphoma (ALCL) that shares key biological aspects with cHL. We conclude that inactivation of PDLIM2 is a recurrent finding in cHL and ALCL, promotes activation of inflammatory signaling pathways and thereby contributes to their pathogenesis. PMID:27538486

    Purpose Breast implant–associated anaplastic large-cell lymphoma (BI-ALCL) is a rare type of T-cell lymphoma that arises around breast implants. The optimal management of this disease has not been established. The goal of this study is to evaluate the efficacy of different therapies used in patients with BI-ALCL to determine an optimal treatment approach. Patients and Methods In this study, we applied strict criteria to pathologic findings, assessed therapies used, and conducted a clinical follow-up of 87 patients with BI-ALCL, including 50 previously reported in the literature and 37 unreported. A Prentice, Williams, and Peterson model was used to assess the rate of events for each therapeutic intervention. Results The median and mean follow-up times were 45 and 30 months, respectively (range, 3 to 217 months). The median overall survival (OS) time after diagnosis of BI-ALCL was 13 years, and the OS rate was 93% and 89% at 3 and 5 years, respectively. Patients with lymphoma confined by the fibrous capsule surrounding the implant had better event-free survival (EFS) and OS than did patients with lymphoma that had spread beyond the capsule (P = .03). Patients who underwent a complete surgical excision that consisted of total capsulectomy with breast implant removal had better OS (P = .022) and EFS (P = .014) than did patients who received partial capsulectomy, systemic chemotherapy, or radiation therapy. Conclusion Surgical management with complete surgical excision is essential to achieve optimal EFS in patients with BI-ALCL. PMID:26628470

    Anaplastic lymphoma kinase (alk) is an oncogenic driver in non-small-cell lung cancer (nsclc). Chromosomal rearrangements involving the ALK gene occur in up to 4% of nonsquamous nsclc patients and lead to constitutive activation of the alk signalling pathway. ALK-positive nsclc is found in relatively young patients, with a median age of 50 years. Patients frequently have brain metastasis. Targeted inhibition of the alk pathway prolongs progression-free survival in patients with ALK-positive advanced nsclc. The results of several recent clinical trials confirm the efficacy and safety benefit of crizotinib and ceritinib in this population. Canadian oncologists support the following consensus statement: All patients with advanced nonsquamous nsclc (excluding pure neuroendocrine carcinoma) should be tested for the presence of an ALK rearrangement. If an ALK rearrangement is present, treatment with a targeted alk inhibitor in the first-line setting is recommended. As patients become resistant to first-generation alk inhibitors, other treatments, including second-generation alk inhibitors can be considered. PMID:27330348

    ALK-positive Anaplastic Large Cell Lymphoma (ALCL) represents a subset of Non-Hodgkin Lymphoma whose treatment benefited from crizotinib development, a dual ALK/MET inhibitor. Crizotinib blocks ALK-triggered pathways such as PI3K/AKT/mTOR, indispensable for survival of ALK-driven tumors. Despite the positive impact of targeted treatment in ALCL, resistant clones are often selected during therapy. Strategies to overcome resistance include the design of second generation drugs and the use of combined therapies that simultaneously target multiple nodes essential for cells survival. We investigated the effects of combined ALK/mTOR inhibition. We observed a specific synergistic effect of combining ALK inhibitors with an mTOR inhibitor (temsirolimus), in ALK+ lymphoma cells. The positive cooperation resulted in an increased inhibition of mTOR effectors, compared to single treatments, a block in G0/G1 phase and induction of apoptosis. The combination was able to prevent the selection of resistant clones, while long-term exposure to single agents led to the establishment of resistant cell lines, with either ALK inhibitor or temsirolimus. In vivo, mice injected with Karpas 299 cells and treated with low dose combination showed complete regression of tumors, while only partial inhibition was obtained in single agents-treated mice. Upon treatment stop the combination was able to significantly delay tumor relapses. Re-challenge of relapsed tumors at a higher dose led to full regression of xenografts in the combination group, but not in mice treated with lorlatinib alone. In conclusion, our data suggest that the combination of ALK and mTOR inhibitors could be a valuable therapeutic option for ALK+ ALCL patients. PMID:27662658

    Crizotinib has achieved astonishing success in advanced non-small-cell lung cancer (NSCLC) patients harboring anaplastic lymphoma kinase (ALK) rearrangement. However, no real-world studies described the clinicopathological characteristics and treatment of such patients in China. Patients were consecutively collected from Sun Yat-sen University Cancer Center. Chi-square test was applied to explore the relationship between ALK fusion status and metastasis sites. Kaplan-Meier methods and multivariable analyses were used to estimate progression-free survival (PFS). A total of 291 advanced NSCLC patients (ALK (+), N = 97; both ALK & epidermal growth factor receptor (EGFR) (-), N = 194) were enrolled. The occurrence of brain metastasis in ALK-positive patients was significantly higher than double-negative ones both at baseline (26.5% vs. 16.5%, P = 0.038) and during treatment (25.8% vs. 11.9%, P = 0.003), but opposite for pleural effusion (6.2% vs. 26.9%, P < 0.001 at baseline; 3.1% vs. 10.3%, P = 0.031 during treatment). ALK-positive patients of 53.6% used crizotinib, whereas others only received chemotherapy (37.1%) or supportive care (9.3%). Usage of crizotinib prolonged PFS compared with chemotherapy in ALK-positive patients (median PFS 17.6 m vs. 4.8 m, P < 0.001). ALK-positive NSCLC had more brain metastasis and less pleural effusion than double-negative ones. Crizotinib showed better PFS than chemotherapy in advanced ALK-positive NSCLC at any line. However, half advanced ALK-positive patients never received crizotinib, which was grim and need improving.

    A 12-year old girl presented with general weakness and weight loss, a localised cervical lymph node enlargement and cutaneous lesions compatible with lymphomatoid papulosis (LyP). Biopsies from lymph node and skin revealed a histological diagnosis of nodal large cell ALK-1- anaplastic lymphoma (ALCL) with a synchronous CD30+ cutaneous lymphoproliferation consistent with lymphomatoid papulosis (LyP). The girl was treated with mistletoe (MT) as monotherapy. Within 1 week after initiation of MT-treatment the skin lesions and lymph node enlargement improved. Under continuing MT-therapy 30 months after diagnosis the patient is still in complete remission. It is not possible to know whether this was a rare case of spontaneous remission of the nodal and skin-manifestations of this CD30+ T-cell lymphoproliferation or whether the observed effect was a specific therapeutic response to MT-treatment.

    In anaplastic large-cell lymphomas, chromosomal translocations involving the kinase domain of anaplastic lymphoma kinase (ALK), generally fused to the 5' part of the nucleophosmin gene, produce highly oncogenic ALK fusion proteins that deregulate cell cycle, apoptosis, and differentiation in these cells. Other fusion oncoproteins involving ALK, such as echinoderm microtubule-associated protein-like 4-ALK, were recently found in patients with non-small-cell lung, breast, and colorectal cancers. Recent research has focused on the development of inhibitors for targeted therapy of these ALK-positive tumors. Because kinase inhibitors that target the inactive conformation are thought to be more specific than ATP-targeted inhibitors, we investigated the possibility of using two known inhibitors, doramapimod and sorafenib, which target inactive kinases, to design new urea derivatives as ALK inhibitors. We generated a homology model of ALK in its inactive conformation complexed with doramapimod or sorafenib in its active site. The results elucidated why doramapimod is a weak inhibitor and why sorafenib does not inhibit ALK. Virtual screening of commercially available compounds using the homology model of ALK yielded candidate inhibitors, which were tested using biochemical assays. Herein we present the design, synthesis, biological activity, and structure-activity relationships of a novel series of urea compounds as potent ALK inhibitors. Some compounds showed inhibition of purified ALK in the high nanomolar range and selective antiproliferative activity on ALK-positive cells.

    We studied the prognostic value of minimal disseminated disease (MDD) and anti-ALK immune response in children with NPM-ALK-positive anaplastic-large cell lymphoma (ALCL) and evaluated their potential for risk stratification. NPM-ALK transcripts were analyzed by RT-PCR in bone marrow/peripheral blood of 128 ALCL patients at diagnosis, whereas ALK antibody titers in plasma were assessed using an immunocytochemical approach. MDD was positive in 59% of patients and 96% showed an anti-ALK response. Using MDD and antibody titer results, patients could be divided into three biological risk groups (bRG) with different prognosis: high risk (bHR): MDD-positive and antibody titer ≤ 1/750, 26/128 (20%); low risk (bLR): MDD negative and antibody titer >1/750, 40/128 (31%); intermediate risk (bIR): all remaining patients, 62/128 (48%). Progression-free survival was 28% (s.e., 9%), 68% (s.e., 6%) and 93% (s.e., 4%) for bHR, bIR and bLR, respectively (P<0.0001). Survival was 71% (s.e., 9%), 83% (s.e., 5%) and 98% (s.e., 2%) for bHR, bIR and bLR (P=0.02). Only bHR and histology other than common type were predictive of higher risk of failure (hazard ratio 4.9 and 2.7, respectively) in multivariate analysis. Stratification of ALCL patients based on MDD and anti-ALK titer should be considered in future ALCL trials to optimize treatment.

    Understanding the mechanisms that control stress-induced apoptosis is critical to explain how tumours respond to treatment, as cancer cells frequently escape drug toxicity by regulating stress response through heat shock protein (HSP) expression. The overexpression of Hsp72, in particular, results in increased incidence of cell transformation, and correlates with poor prognosis in a wide range of cancers. We have shown that Hsp72 assists folding of oncogenic NPM-ALK kinase in anaplastic large-cell lymphomas (ALCLs), but its role in the maintenance of the malignant phenotype remains uncertain. Therefore, we assessed Hsp72 expression in ALCLs, investigating more in detail the mechanisms that regulate its status and activity. We found that Hsp72 is unique among the HSPs involved in tumourigenesis to be overexpressed in ALK(+) tumours and cell lines and to be induced by stress. Different from other HSPs, Hsp72 prevents cell injury, Bax activation and death by apoptosis in ALK(+) cells, acting both upstream and downstream of mitochondria. Conversely, Hsp72 is underexpressed in ALK(-) ALCL cells, and it is unable to protect cells from apoptosis under stress. Moreover, when Hsp72 expression is reduced following NPM-ALK inhibition, lymphoma cells undergo apoptosis, demonstrating the importance of Hsp72 in regulating ALCL stress response and drug sensitivity.

    Due to its selective overexpression on the malignant cells of Hodgkin's lymphoma (HL) and large cell anaplastic lymphoma (ALCL), CD30 is an excellent target for immunotherapy of these diseases. The fully human monoclonal anti-CD30-antibody 5F11 has been shown to be effective against CD30-expressing cell lines both in vitro and in vivo. In addition, 5F11 shows promising antitumor activity in phase 1/2 clinical trials. To extend these promising results, the authors evaluated combinations of 5F11 with conventional cytostatic drugs against a variety of lymphoma cell lines in vitro. Most combinations tested showed at least additive cytotoxic effects on the HL-derived cell lines L428, L540, and L1236 and the ALCL-derived cell line Karpas 299 as measured by proliferation assays (XTT) and the induction of apoptosis (annexin-V FACS analysis). The most impressive results were detected with the combination of 5F11 and gemcitabine or etoposide. The data suggest that the combination of the human antibody 5F11 with conventional chemotherapy might be beneficial in the combined chemo-immunotherapy of CD30-positive lymphomas.

    Primary breast lymphoma is a rare disease and accounts for 0.5% of cases of breast cancer. Most primary breast lymphomas develop from B cells, and the involvement of T cells is rare. Anaplastic large cell lymphoma (ALCL) is a recently discovered T-cell lymphoma associated with breast implants. Only a few cases have been reported to date. It is believed that the incidence of ALCL is increasing because of the increasing number of breast implants. The clinical presentation is variable and can manifest as a palpable mass in the breast or armpit, breast pain, or capsular contracture. Because of the rarity of the disease and the lack of knowledge to date, clinical diagnosis is often delayed, with consequent delays in treatment. The cause and pathogenesis have not been fully elucidated, and there are no evidence-based guidelines for diagnosis, treatment, or follow-up of this disease. We present a review of cases of patients with silicone breast implants, including ALCL, a rare type of breast cancer that is still under study, and silicone-induced granuloma of breast implant capsule and its differential diagnosis, and discuss if a silicone-induced granuloma of breast implant capsule could be the precursor of the disease.

    IgG4-related sclerosing disease is an established disease entity with characteristic clinicopathological features. Recently, the association between IgG4-related sclerosing disease and the risk of malignancies has been suggested. IgG4-related autoimmune pancreatitis with pancreatic cancer has been reported. Further, a few cases of extraocular malignant lymphoma in patients with IgG4-related sclerosing disease have also been documented. Herein, we describe the first documented case of anaplastic large cell lymphoma (ALCL) following IgG4-related autoimmune pancreatitis and cholecystitis and diffuse large B-cell lymphoma (DLBCL). A 61-year-old Japanese male, with a past history of DLBCL, was detected with swelling of the pancreas and tumorous lesions in the gallbladder. Histopathological study of the resected gallbladder specimen revealed diffuse lymphoplasmacytic infiltration with fibrosclerosis in the entire gallbladder wall. Eosinophilic infiltration and obliterative phlebitis were also noted. Immunohistochemically, many IgG4-positive plasma cells had infiltrated into the lesion, and the ratio of IgG4/IgG-positive plasma cells was 71.6%. Accordingly, a diagnosis of IgG4-related cholecystitis was made. Seven months later, he presented with a painful tumor in his left parotid gland. Histopathological study demonstrated diffuse or cohesive sheet-like proliferation of large-sized lymphoid cells with rich slightly eosinophilic cytoplasm and irregular-shaped large nuclei. These lymphoid cells were positive for CD30, CD4, and cytotoxic markers, but negative for CD3 and ALK. Therefore, a diagnosis of ALK-negative ALCL was made. It has been suggested that the incidence of malignant lymphoma may be high in patients with IgG4-related sclerosing disease, therefore, intense medical follow-up is important in patients with this disorder.

    A high rate of aerobic glycolysis is a hallmark of malignant transformation. Accumulating evidence suggests that diverse regulatory mechanisms mediate this cancer-associated metabolic change seen in a wide spectrum of cancer. The echinoderm microtubule associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) fusion protein is found in approximately 3-7% of non-small cell lung carcinomas (NSCLC). Molecular evidence and therapeutic effectiveness of FDA-approved ALK inhibitors indicated that EML4-ALK is a driving factor of lung tumorigenesis. A recent clinical study showed that NSCLC harboring EML4-ALK rearrangements displayed higher glucose metabolism compared to EML4-ALK-negative NSCLC. In the current work, we presented evidence that EML4-ALK is coupled to overexpression of hexokinase II (HK2), one of the rate-limiting enzymes of the glycolytic pathway. The link from EML4-ALK to HK2 upregulation is essential for a high rate of glycolysis and proliferation of EML4-ALK-rearranged NSCLC cells. We identified hypoxia-inducible factor 1α (HIF1α) as a key transcription factor to drive HK2 gene expression in normoxia in these cells. EML4-ALK induced hypoxia-independent but glucose-dependent accumulation of HIF1α protein via both transcriptional activation of HIF1α mRNA and the PI3K-AKT pathway to enhance HIF1α protein synthesis. The EML4-ALK-mediated upregulation of HIF1α, HK2 and glycolytic metabolism was also highly active in vivo as demonstrated by FDG-PET imaging of xenografts grown from EML4-ALK-positive NSCLC cells. Our data reveal a novel EML4-ALK-HIF1α-HK2 cascade to enhance glucose metabolism in EML4-ALK-positive NSCLC. PMID:27132509

    In the present study we assessed the activity of the next-generation anaplastic lymphoma kinase (ALK)-tyrosine kinase inhibitor (-TKI) alectinib, in patients with ALK-postive, advanced non-small cell lung cancer (NSCLC) and central nervous system (CNS) metastases. NSCLCs with ALK-positive disease, as assessed by fluorescence in situ hybridization, and CNS metastases were treated with alectinib 600 mg BID. Included patients were followed prospectively in order to evaluate the efficacy of the drug, with particular emphasis on activity in the CNS. Eleven consecutive patients were enrolled. The majority of them were pretreated with crizotinib (n = 10, 90.9 %), and cranial radiotherapy (n = 8, 72.7 %). Six of the seven patients with measurable CNS disease experienced a CNS response, including three patients who were naïve for cranial radiation. Median duration of response was 8 months. For the whole population, median CNS-progression-free survival (-PFS), systemic-PFS, overall-PFS, overall survival, and 1-year survival were 8, 11, 8, 13 months, and 31.1 %, respectively. Two patients experiencing a CNS response were assessed for alectinib's concentrations in serum and cerebro-spinal fluid (CSF), and showed a CSF-to-serum ratio ranging from 0.001 to 0.003 ng/mL. Alectinib is highly active against CNS metastases from ALK-positive NSCLCs, irrespective of prior treatment(s) with ALK-TKI(s) and/or cranial radiotherapy. The low CSF-to-serum ratio of alectinib suggests that measuring the concentrations of the drug in the CSF may not be a reliable surrogate of its distribution into the CNS.

    Non-small cell lung cancer (NSCLC) represents the paradigm of personalized treatment of human cancer. Several oncogenic druggable alterations have been so far identified, with anaplastic lymphoma kinase (ALK) gene rearrangements being one of the newest and most appealing. Presence of ALK fusions is associated with some particular clinical and pathological features, including a preferential seeding into the central nervous system (CNS). In addition, ALK rearrangements are recognized as the strongest predictor for benefit of anti-ALK therapy. Crizotinib, the first ALK inhibitor (ALK-I) licensed in clinical practice, is the standard of care for newly diagnosed patients. Unfortunately, within the first year of treatment the majority of patients become insensitive to crizotinib, with approximately one third of them developing brain metastases (BMs). Optimal management of BMs is one of the major challenges in treating ALK positive NSCLC. Several novel and highly CNS penetrant ALK-Is are currently under investigation and available data clearly indicated their ability in controlling intracranial disease. PMID:28149753

    Although the Ventana immunohistochemistry (IHC) platform for detecting anaplastic lymphoma kinase gene (ALK) (D5F3) expression was recently approved by the US Food and Drugs Administration (FDA), fluorescence in situ hybridization (FISH) is still the “gold-standard” method recommended by the US National Comprehensive Cancer Network (NCCN) guideline for NSCLC. We evaluated 6 ALK-positive lung adenocarcinoma patients who tested Ventana IHC-positive and FISH-negative and assessed their clinical responses to the ALK tyrosine kinase inhibitor (TKI) crizotinib. Histologic and cytologic specimens from the 6 patients were stained with Ventana anti-ALK(D5F3) rabbit monoclonal primary antibody using the OptiView™ DAB IHC detection kit and OptiView™ amplification kit on a Ventana BenchMark XT processor. In addition, they were also tested by FISH, qRT-PCR, next-generation sequencing (NGS), and RNAscope ISH analysis. All patients received crizotinib treatment and their follow-up clinical data were recorded. The objective response rate achieved with crizotinib therapy was 66.7% (4/6 partial responses and 2/6 stable disease). One patient in whom a new fusion type (EML4->EXOC6B->ALK fusion) was identified obtained a partial response. These findings indicate that patients with ALK-positive lung adenocarcinoma who test Ventana IHC-positive and FISH-negative may still respond to crizotinib therapy. PMID:27418132

    The International Peripheral T-Cell Lymphoma Project is a collaborative effort designed to gain better understanding of peripheral T-cell and natural killer (NK)/T-cell lymphomas (PTCLs). A total of 22 institutions in North America, Europe, and Asia submitted clinical and pathologic information on PTCLs diagnosed and treated at their respective centers. Of the 1314 eligible patients, 181 had anaplastic large-cell lymphoma (ALCL; 13.8%) on consensus review: One hundred fifty-nine had systemic ALCL (12.1%) and 22 had primary cutaneous ALCL (1.7%). Patients with anaplastic lymphoma kinase-positive (ALK(+)) ALCL had a superior outcome compared with those with ALK(-) ALCL (5-year failure-free survival [FFS], 60% vs 36%; P = .015; 5-year overall survival [OS], 70% vs 49%; P = .016). However, contrary to prior reports, the 5-year FFS (36% vs 20%; P = .012) and OS (49% vs 32%; P = .032) were superior for ALK(-) ALCL compared with PTCL, not otherwise specified (PTCL-NOS). Patients with primary cutaneous ALCL had a very favorable 5-year OS (90%), but with a propensity to relapse (5-year FFS, 55%). In summary, ALK(-) ALCL should continue to be separated from both ALK(+) ALCL and PTCL-NOS. Although the prognosis of ALK(-) ALCL appears to be better than that for PTCL-NOS, it is still unsatisfactory and better therapies are needed. Primary cutaneous ALCL is associated with an indolent course.

    Posttransplant lymphoproliferative disorder (PTLD) comprises a spectrum ranging from polyclonal hyperplasia to aggressive monoclonal lymphomas. The majority of PTLDs are of B-cell origin while T-cell PTLDs and Hodgkin lymphoma-like PTLDs are uncommon. Here, we report a unique case of a 56-year-old man in whom a lymphoma with two distinct components developed as a duodenal mass seventeen years following a combined kidney-pancreas transplant. This PTLD, which has features not previously reported in the literature, consisted of one component of CD20 positive and EBV negative monomorphic diffuse large B-cell lymphoma. The other component showed anaplastic morphology, expressed some but not all T-cell markers, failed to express most B-cell markers except for PAX5, and was diffusely EBV positive. Possible etiologies for this peculiar constellation of findings are discussed and the literature reviewed for "composite-like" lymphomas late in the posttransplant setting.

    Purpose Alectinib is an anaplastic lymphoma kinase (ALK) -specific kinase inhibitor that seems to be effective against non-small-cell lung cancer (NSCLC) with a variety of ALK mutations. The primary analysis of AF-001JP reported a promising overall response rate. To assess progression-free survival (PFS) and overall survival (OS), patients from the phase II part of AF-001JP were followed up for approximately 3 years. Patients and Methods Oral alectinib 300 mg was administered twice per day to patients with ALK inhibitor-naïve, ALK-positive NSCLC who had progressed after one or more regimens of previous chemotherapy. In this long-term follow-up, efficacy (PFS, OS), correlation between tumor shrinkage and PFS, safety of alectinib, and relief of cancer symptoms were evaluated. Results At the updated data cutoff (September 10, 2015; first patient in August 30, 2011, last patient in April 18, 2012), 25 of 46 phase II patients were still receiving alectinib. Disease progression was confirmed in 18 patients (39%); median PFS was not reached (3-year PFS rate, 62%; 95% CI, 45 to 75). Fourteen patients had brain metastases at baseline; of these, 6 remained in the study without CNS and systemic progression. Tumor shrinkage and PFS showed no correlation. The 3-year OS rate was 78% (13 events). The most common treatment-related adverse event (all grades) was increased blood bilirubin (36.2%). Most cancer symptoms were relieved early, and medication for symptoms was dramatically decreased during alectinib therapy. Conclusion Alectinib was effective in this 3-year follow-up with a favorable safety profile over a long administration period in ALK-positive NSCLC without previous ALK inhibitor treatment.

    A 24-year-old woman was hospitalized with seizures in 2002. Magnetic resonance imaging demonstrated an intraspinal mass and inhomogeneous gadolinium enhancement along the cerebrospinal meninges. Cerebrospinal fluid (CSF) cytology showed large atypical cells expressing CD2, cytoplasmic CD3, CD7, CD13 and CD30. The patient was finally diagnosed with primary central nervous system anaplastic large cell lymphoma (ALCL). She completed 5 courses of methotrexate (MTX)/ procarbazine (PCZ)/ vincristine (VCR) (MPV) chemotherapy, followed by 2 courses of high dose cytarabine (AraC) and achieved a complete remission. In 2003, she suffered from headache. CSF analysis showed atypical lymphoid cells expressing CD 30. First CNS relapse was diagnosed. She then underwent autologous peripheral blood stem cell transplantation (auto-PBSCT) after administration of thiotepa, buslfan, and cyclophosphamide. However, second CNS relapse occurred in 2004. She received 5 courses of MPV chemotherapy followed by 36 Gy of craniospinal irradiation. Although there was no recurrence of the CNS disease, a third relapse was detected in the right breast in 2009. Pathological and immunohistochemistry analysis revealed ALK-1 positive ALCL. She was treated with 6 courses of cyclophosphamide/adriamycin/vincristine/predonine (CHOP) chemotherapy and 30.6 Gy of local radiation therapy. She has remained in remission for 6 years, to date, since the last therapy and has an excellent quality of life.

    The cytological examination of peri-prosthetic breast effusions allowed the diagnosis of bilateral breast-implant ALK-negative anaplastic large cell lymphoma (BI-ALCL) in the case reported. Ten years after reconstructive surgery with bilateral breast implants, a large unilateral seroma developed and was cytologically analyzed. The presence of CD30 and CD4-positive large-sized atypical lymphoid cells exhibiting horseshoe-shaped nuclei and a brisk mitotic activity rendered the diagnosis of BI-ALCL. Similar cells were seen in the peri-prosthetic fluid intraoperatively collected from the contralateral breast. Although initial histological analysis of the capsulectomy specimens showed unilateral tumor, the cytological findings prompted a more thorough tissue sampling, resulting in the diagnosis of bilateral disease. BI-ALCL usually follows an indolent clinical course; however, there are reported cases with an aggressive behavior. While the presence of bilateral disease is a putative risk factor for a bad prognosis, the small number of cases reported precludes a definitive assessment of this risk. Since most BI-ALCL present with late seromas, cytologic analysis of these effusions in women with breast implants should be mandatory. Cytology is a safe tool for diagnosis and follow-up of patients with breast implant-related late seromas, sometimes proven more sensitive than histological analysis. Complete bilateral capsulectomy and a detailed histological analysis should follow a cytological diagnosis of BI-ALCL in a breast effusion in order to avoid false negative diagnoses. Our case constitutes the first published report of a bilateral BI-ALCL diagnosed by cytology. Diagn. Cytopathol. 2016;44:623-627. © 2016 Wiley Periodicals, Inc.

    Rhabdomyosarcoma is a rare soft tissue sarcoma that typically affects children, adolescents, and young adults. Despite treatment via a multidisciplinary approach, the prognosis of advance-stage rhabdomyosarcomas remains poor, and a new treatment strategy is needed. Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase that is a potential target for specific inhibitors. In this study, we investigated 116 rhabdomyosarcomas using a polymer-based ALK immunostaining method and correlated the results with clinicopathological parameters. In addition, we examined ALK status using dual-color fluorescence in situ hybridization, PCR, and sequencing. In immunohistochemical analysis, ALK was detected in 2 (6%) of 33 embryonal rhabdomyosarcomas, 42 (69%) of 61 alveolar rhabdomyosarcomas, and 0 (0%) of 22 other subtypes, including pleomorphic, adult-spindle-cell/sclerosing, and epithelioid variants. Compared with ALK-negative alveolar rhabdomyosarcomas, ALK-positive ones are presented with metastatic spread more frequently and showed a greater extent of myogenin reactivity. Overall survival was not associated with ALK expression. FOXO1 rearrangement was significantly associated with ALK immunoreactivity. The median ALK copy number was greater in ALK-positive tumors than in ALK-negative tumors. Most (93%) cases tested showed no selective increase in the ALK gene dosage. ALK selective amplification and low-level selective gain were noted in one and three cases, respectively. Further, a high-polysomy pattern (≥4 ALK copies in ≥40% of cells) was observed in seven cases. A significant increase in the ALK copy number was exclusive to the ALK-immunopositive cohort, but it was uncommon, accounting for only 30% of the 37 ALK-positive rhabdomyosarcomas. ALK gene rearrangement was not observed in either cohort, while an ALK somatic mutation (I1277T) was found in one ALK-negative embryonal case. Although it remains controversial whether ALK expression without gene rearrangement

    Anaplastic lymphoma kinase (ALK) gene fusions occur in 3%–7% of non-small-cell lung cancer (NSCLC) cases. Ceritinib, a once-daily, oral ALK inhibitor, has activity against crizotinib-resistant and crizotinib-naïve NSCLC, including brain metastases. Ceritinib (Zykadia™) was granted accelerated approval by the US Food and Drug Administration in 2014 for treating crizotinib-resistant ALK-positive NSCLC. Adverse events (AEs), particularly gastrointestinal (GI) AEs, are commonly experienced at the recommended dose of 750 mg/d and ∼38% of patients require dose interruption or reduction for GI AEs. This case study details our experience with the use of proactive GI AE management regimens in patients treated with ceritinib (750 mg/d) across two study sites. Proactive Regimens A and B were implemented in patients with metastatic ALK-positive NSCLC treated with ceritinib to manage drug-related GI AEs. Regimen A comprised ondansetron and diphenoxylate/atropine or loperamide, taken 30 minutes prior to ceritinib dose. Regimen B included dicyclomine (taken with the first ceritinib dose), ondansetron (taken 30 minutes prior to ceritinib dose for the first seven doses), and loperamide (taken as needed with the onset of diarrhea). The proactive medications were tapered off depending on patient tolerability to ceritinib. Nine patient cases are presented. Starting Regimens A or B before the first dose of ceritinib, or as soon as GI symptoms were encountered, prevented the need for dose reduction due to GI toxicity in eight of the nine patients. Using these regimens, 78% of patients were able to remain on 750 mg/d fasting. Two patients received 23 months and 16 months of therapy and remain on ceritinib 750 mg/d and 600 mg/d, respectively. Although not currently recommended or implemented in clinical studies, based on the patients evaluated here, upfront or proactive treatment plans that address AEs early on can allow the majority of patients to remain on the approved 750 mg

    We investigated the response of SUDHL-1 and L428 cells, derived from t(2;5)-anaplastic large cell lymphoma (ALCL) and Hodgkin's disease (HD), respectively, to recombinant adenoviruses expressing cyclin-dependent kinase inhibitors (CDKIs) p27Kip1 (Adp27), p21Waf1 (Adp21) and p16INK4A (Adp16). Cell cycle analysis of SUDHL-1 cells after 24 h of infection with 200 multiplicity of infection (MOI) of Adp27, Adp21, and Adp16, showed very high levels of cell debris in the subG1 area. The magnitude of cell debris-events was Adp27/Adp21 > Adp16. Cell cycle analysis of L428 cells revealed absence of cell debris and increased G2 phase in all the groups of cells tested as compared to the controls (mock and AdNull). A minimal increase in G1 phase was also evident in cells infected with Adp27 (52%) compared to uninfected cells (43%), AdNull (45%) and to cells infected with Adp21 (37%) and Adp16 (31%). The presence of significant levels of Coxsackie-adenovirus receptor (CAR) on the cell surface of L428 cells excluded the cell membrane-barrier as responsible for the differences in cell observed in response to the recombinant adenovirus-mediated CDKIs expression as compared to SUDHL-1. We also showed that the recombinant adenovirus-mediated cytotoxicity measured as apoptosis was MOI- and vector-dependent in SUDHL-1 cells at lower MOI (100). In conclusion, the therapeutic effect induced by recombinant adenoviruses expressing p27Kip1, p21Waf1 and p16INK4A is cell-dependent in cells derived from selected lymphoid malignancies. Biochemical cellular differences more than cell surface barriers seem to be responsible for differences in response to recombinant adenovirus-mediated expression of cytotoxic genes. Moreover, the cytotoxicity of recombinant adenoviruses expressing p27Kip1, p21Waf1 and p16INK4A may be further explored as a tool for gene therapy of t(2;5)-derived ALCL.

    Given the excellent results of the clinical trials with anaplastic lymphoma kinase (ALK) inhibitors, the importance of accurately identifying ALK-positive lung carcinoma patients has never been greater. It brings with it a pressing need for harmonized development of companion diagnostics, for economic, scientific and medical reasons. Therefore, it is crucial that ALK testing assays become more standardized both in performance (analytical phase) and interpretation (post-analytical phase). We find that both methods currently recommended by College of American Pathologists/International Association for the Study of Lung Cancer/Association for Molecular Pathology guidelines (FISH and Immunohistochemistry) are reasonable approaches for primary routine ALK testing, if at least 50 tumor cells are scored and protocols are strictly followed. Moreover, due to the high demand to study multiple predictive biomarkers on different assay platforms, quick and reliable approaches to achieve this are essential to guide treatment decisions.

    On August 26, 2011, the U.S. Food and Drug Administration (FDA) approved crizotinib (XALKORI Capsules, Pfizer Inc.) for treatment of patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) that is anaplastic lymphoma kinase (ALK) positive as detected by an FDA-approved test. The Vysis ALK Break-Apart FISH Probe Kit (Abbott Molecular, Inc.) was approved concurrently. In two multicenter, single-arm trials, patients with locally advanced or metastatic ALK-positive NSCLC previously treated with one or more systemic therapies received crizotinib orally at a dose of 250 mg twice daily. In 119 patients with ALK-positive NSCLC by local trial assay, the objective response rate (ORR) was 61% [95% confidence intervals (CI), 52%-70%] with a median response duration of 48 weeks. In 136 patients with ALK-positive NSCLC by the to-be-marketed test, the ORR was 50% (95% CI, 42%-59%) with a median response duration of 42 weeks. The most common adverse reactions (≥25%) were vision disorder, nausea, diarrhea, vomiting, edema, and constipation. Accelerated approval was granted on the basis of the high ORRs and durable responses. On November 20, 2013, crizotinib received full approval based on an improvement in progression-free survival in patients with metastatic ALK-positive NSCLC previously treated with one platinum-based chemotherapy regimen.

    Some features found on chest computed tomography (CT), such as central tumor location, large pleural effusion, and the absence of a pleural tail, and a patient age of less than 60 years, have been suggested to be useful in predicting anaplastic lymphoma kinase (ALK) rearrangement in patients with non-small cell lung cancer (NSCLC).A 68-year-old female patient with a history of gynecological treatment was found to have a cavitary mass in the right lower lobe on an annual chest roentgenogram. The tumor was located in the peripheral area with a pleural tail showing no pleural effusion. In addition, two pure ground-glass-opacity nodules (p-GGNs) in the right upper lobe of the lung were detected on consecutive chest CT scans. The patient underwent right lower lobectomy, partial resection of the right upper lobe, and hilar mediastinal lymph node dissection for complete resection of each tumor. The pathological diagnosis was invasive mucinous adenocarcinoma with signet-ring cells for the cavitary mass in the right lower lobe and invasive adenocarcinoma for the rest of the p-GGNs; subcarinal lymph node metastasis was also detected. The ALK rearrangement was detected by fluorescence in situ hybridization from the cavitary mass. The patient underwent four cycles of cisplatin and vinorelbine chemotherapy as standard adjuvant chemotherapy for pStage III NSCLC. The ALK fusion gene status of NSCLC with atypical CT features should also be investigated.

  9. Anaplastic lymphoma kinase (ALK) inhibitors in the treatment of ALK-driven lung cancers.

    PubMed

    Roskoski, Robert

    2017-03-01

    Anaplastic lymphoma kinase is expressed in two-thirds of the anaplastic large-cell lymphomas as an NPM-ALK fusion protein. Physiological ALK is a receptor protein-tyrosine kinase within the insulin receptor superfamily of proteins that participates in nervous system development. The EML4-ALK fusion protein and four other ALK-fusion proteins play a fundamental role in the development in about 5% of non-small cell lung cancers. The amino-terminal portions of the ALK fusion proteins result in dimerization and subsequent activation of the ALK protein kinase domain that plays a key role in the pathogenesis of various tumors. Downstream signaling from the ALK fusion protein leads to the activation of the Ras/Raf/MEK/ERK1/2 cell proliferation module and the JAK/STAT cell survival pathways. Moreover, nearly two dozen ALK activating mutations are involved in the pathogenesis of childhood neuroblastomas. The occurrence of oncogenic ALK-fusion proteins, particularly in non-small cell lung cancer, has fostered considerable interest in the development of ALK inhibitors. Crizotinib was the first such inhibitor approved by the US Food and Drug Administration for the treatment of ALK-positive non-small cell lung cancer in 2011. The median time for the emergence of crizotinib drug resistance is 10.5 months after the initiation of therapy. Such resistance prompted the development of second-generation drugs including ceritinib and alectinib, which are approved for the treatment of non-small cell lung cancer. Unlike the single gatekeeper mutation that occurs in drug-resistant epidermal growth factor receptor in lung cancer, nearly a dozen different mutations in the catalytic domain of ALK fusion proteins have been discovered that result in crizotinib resistance. Crizotinib, ceritinib, and alectinib form a complex within the front cleft between the small and large lobes of an inactive ALK protein-kinase domain with a compact activation segment. These drugs are classified as type I½ B

    Inflammatory myofibroblastic tumors (IMT) of the central nervous system (CNS) are rare entities that have a predilection for local recurrences. Approximately half of the inflammatory myofibroblastic tumors contain translocations that result in the over-expression of the anaplastic lymphoma kinase (ALK) gene. We hereby present the case of a patient diagnosed with a left parieto-occipital IMT that recurred after multiple surgeries and radiotherapy. Immuno-histochemical examination of the tumor demonstrated ALK overexpression and the presence of an ALK rearrangement observed in lung cancers. The patient was subsequently started on an ALK inhibitor. A response evaluation criteria in solid tumors (RECIST) partial response was observed by the seventh month of ALK inhibition and the tumor remained in control for 14 months. The current case reiterates the activity of ALK inhibitors within the CNS and suggests that radiotherapy may potentiate the permeability of ALK inhibitors in CNS tumors addicted to ALK signalling.

    The development of inhibitors for the tyrosine anaplastic lymphoma kinase (ALK) has advanced rapidly, driven by biology and medicinal chemistry. The first generation ALK inhibitor crizotinib was granted US FDA approval with only four years of preclinical and clinical testing. Although this drug offers significant clinical benefit to the ALK-positive patients, resistance has been developed through a variety of mechanisms. In addition to ceritinib, alectinib is another second-generation ALK inhibitor launched in 2014 in Japan. This drug has a unique chemical structure bearing a 5H-benzo[b]carbazol-11(6H)-one structural scaffold with an IC50 value of 1.9 nmol/L, and is highly potent against ALK bearing the gatekeeper mutation L1196M with an IC50 of 1.56 nmol/L. In the clinic, alectinib is highly efficacious in treatment of ALK-positive non-small cell lung cancer (NSCLC), and retains potency to combat crizotinib-resistant ALK mutations L1196M, F1174L, R1275Q and C1156Y.

    Background Crizotinib was the first agent approved for the treatment of anaplastic lymphoma kinase (ALK)–positive (+) non-small-cell lung cancer (nsclc), followed by ceritinib. However, patients eventually progress or develop resistance to crizotinib. With limited real-world data available, the objective of the present work was to evaluate treatment patterns and survival after crizotinib in patients with locally advanced or metastatic ALK+ nsclc in Canada. Methods In this retrospective study at 6 oncology centres across Canada, medical records of patients with locally advanced or metastatic ALK+ nsclc were reviewed. Demographic and clinical characteristics, treatments, and outcomes data were abstracted. Analyses focused on patients who discontinued crizotinib treatment. Results Of the 97 patients included, 9 were crizotinib-naïve, and 39 were still receiving crizotinib at study end. The 49 patients who discontinued crizotinib treatment were included in the analysis. Of those 49 patients, 43% received ceritinib at any time, 20% subsequently received systemic chemotherapy only (but never ceritinib), and 37% received no further treatment or died before receiving additional treatment. Median overall survival from crizotinib discontinuation was shorter in patients who did not receive ceritinib than in those who received ceritinib (1.7 months vs. 20.4 months, p < 0.001). In a multivariable analysis, factors associated with poorer survival included lack of additional therapies (particularly ceritinib), male sex, and younger age, but not smoking status; patients of Asian ethnicity showed a nonsignificant trend toward improved survival. Conclusions A substantial proportion of patients with ALK+ nsclc received no further treatment or died before receiving additional treatment after crizotinib. Treatment with systemic agents was associated with improved survival, with ceritinib use being associated with the longest survival. PMID:28050149

    Purpose Alectinib has shown activity in the CNS in phase I and II studies. To further evaluate this activity, we pooled efficacy and safety data from two single-arm phase II studies (NP28761 and NP28673; ClinicalTrials.gov identifiers: NCT01871805 and NCT01801111, respectively) in patients with ALK-positive non-small-cell lung cancer (NSCLC). Patients and Methods Both studies included patients with ALK-positive NSCLC who had previously received crizotinib; all patients received alectinib 600 mg twice per day. The primary end point in both studies was independent review committee (IRC)-assessed objective response rate (ORR; by Response Evaluation Criteria in Solid Tumors [RECIST] version 1.1). Additional end points (all by IRC) included CNS ORR (CORR), CNS disease control rate (CDCR), and CNS duration of response (CDOR). Results One hundred thirty-six patients had baseline CNS metastases (60% of the overall study populations); 50 patients (37%) had measurable CNS disease at baseline. Ninety-five patients (70%) had prior CNS radiotherapy; 55 patients completed the CNS radiotherapy more than 6 months before starting alectinib. Median follow-up time was 12.4 months (range, 0.9 to 19.7 months). For patients with baseline measurable CNS disease, IRC CORR was 64.0% (95% CI, 49.2% to 77.1%), CDCR was 90.0% (95% CI, 78.2% to 96.7%), and median CDOR was 10.8 months (95% CI, 7.6 to 14.1 months). For patients with measurable and/or nonmeasurable baseline CNS disease, IRC CORR was 42.6% (95% CI, 34.2% to 51.4%), CDCR was 85.3% (95% CI, 78.2% to 90.8%), and median CDOR was 11.1 months (95% CI, 10.3 months to not evaluable). CORR was 35.8% (95% CI, 26.2% to 46.3%) for patients with prior radiotherapy (n = 95) and 58.5% (95% CI, 42.1% to 73.7%) for patients without prior radiotherapy (n = 41). As previously reported, alectinib was well tolerated, regardless of baseline CNS disease. Conclusion Alectinib showed good efficacy against CNS metastases, in addition to systemic activity

    Introduction: The incidence of echinoderm microtubule-associated protein-like4-anaplastic lymphoma kinase (EML4-ALK) mutation among surgically treated patients with adenocarcinoma of the lung of the Eastern European ethnicity is underreported. The aim of this trial was the determination of EML4-ALK mutation frequency in investigated population, and the evaluation of correlations between lung adenocarcinoma subtype and clinical characteristics with mutation status. Patients and methods: This was a prospective trial which included 195 patients with adenocarcinoma of the lung who underwent surgical treatment. ALK mutation screening was performed by immunohistochemistry (IHC). IHC scores of 2+ and 3+ were regarded as positive. Confirmatory FISH was performed in all IHC positive and in 2:1 ratio in negative patients. Results: Overall ALK mutation rate established by IHC was 6.2%, while FISH confirmed rate of 5.1%. The FISH confirmed ALK positivity in 7.6% Hungarians, 5.5% Serbians, and 6.6% Slovakians. Acinar subtype of adenocarcinoma of the lung was significantly (p=0.02) related to EML4-ALK positive mutation status. Most of the patients were males (56.9%), smokers (50.8%), or former smokers (28.7%) with acinar (55.4%) or solid (35.9%) adenocarcinoma of the lung. Sensitivity and specificity of IHC were 100% and 98.9% respectively. Conclusions: ALK mutation rate in surgically treated patients with adenocarcinoma of the lung was found to be 6.2% by IHC and 5.1% by FISH. Acinar subtype of the adenocarcinoma of the lung was significantly related to ALK positive mutation. PMID:27994656

    Rhabdomyosarcoma (RMS) is the most frequent soft tissue tumor in childhood and arises from immature mesenchymal cells committed to skeletal muscle differentiation. Anaplastic Lymphoma Kinase (ALK) is a receptor tyrosine kinase aberrantly expressed in several cancers. Moreover, ALK full-length receptor protein has been observed in RMS, although its clinical and functional significance is yet controversial. The role of ALK and its clinical relevance were investigated in a selected cohort of 74 FFPE pediatric RMS and a panel of RMS cell lines, evaluating its gene and protein status, utilizing Fluorescent In Situ Hybridization (FISH), immunohistochemistry (IHC) and Western blot approaches. Moreover, to get insight into its possible therapeutic relevance, effects of ALK silencing on cell proliferation, invasion and apoptosis were studied in RMS cells. ALK IHC positivity was significantly correlated with gene copy number gain, the alveolar subtype, PAX3/7-FOXO1 rearrangements, the presence of metastasis at diagnosis and a worse overall outcome. Furthermore, EML4-ALK fusion gene associated with higher protein expression was identified in an embryonal RMS. ALK silencing in RH30 ALK positive cells strongly inhibited invasion capability. Overall, our data suggest a potential role of ALK in pediatric RMS. PMID:27385213

    Background Anaplastic lymphoma kinase (ALK) fusions need to be accurately and efficiently detected for ALK inhibitor therapy. Fluorescence in situ hybridization (FISH) remains the reference test. Although increasing data are supporting that ALK immunohistochemistry (IHC) is highly concordant with FISH, IHC screening needed to be clinically and prospectively validated. Patients and methods In the AF-001JP trial for alectinib, 436 patients were screened for ALK fusions through IHC (n = 384) confirmed with FISH (n = 181), multiplex RT-PCR (n = 68), or both (n = 16). IHC results were scored with iScore. Result ALK fusion was positive in 137 patients and negative in 250 patients. Since the presence of cancer cells in the samples for RT-PCR was not confirmed, ALK fusion negativity could not be ascertained in 49 patients. IHC interpreted with iScore showed a 99.4% (173/174) concordance with FISH. All 41 patients who had iScore 3 and were enrolled in phase II showed at least 30% tumor reduction with 92.7% overall response rate. Two IHC-positive patients with an atypical FISH pattern responded to ALK inhibitor therapy. The reduction rate was not correlated with IHC staining intensity. Conclusions Our study showed (i) that when sufficiently sensitive and appropriately interpreted, IHC can be a stand-alone diagnostic for ALK inhibitor therapies; (ii) that when atypical FISH patterns are accompanied by IHC positivity, the patients should be considered as candidates for ALK inhibitor therapies, and (iii) that the expression level of ALK fusion is not related to the level of response to ALK inhibitors and is thus not required for patient selection.

    Crizotinib achieves excellent systemic control in anaplastic lymphoma kinase-rearranged (ALK+) non-small cell lung cancer (NSCLC); however, central nervous system (CNS) metastases frequently occur as an early event. Whole brain irradiation, the standard treatment, results in neurocognitive impairment. We present a case series of three ALK+ NSCLC patients with progressing CNS metastases who were treated with pulse-dose crizotinib followed by ceritinib. Three ALK+ NSCLC patients treated between 2011 and 2014 (two males, two never smokers, age range 20-54years, all echinoderm microtubule-associated protein-like 4/ALK rearrangement), were diagnosed with progressing cerebral disease while receiving crizotinib. Clinico-pathological characteristics, treatments, and outcomes were analyzed. In two patients the progression was limited to the CNS, and radiological evidence of leptomeningeal spread was present in one patient. Sequential use of crizotinib 500mg administered once daily (pulse-dose) followed by ceritinib on progression achieved control of the disease in the CNS for over 18 months and over 7 months in Patient 1 and Patient 2, respectively. This strategy provided durable CNS control after whole-brain radiotherapy failure in Patient 1, and allowed the whole-brain radiotherapy to be deferred in Patient 2. Limited CNS progression was documented in Patient 3 while he was on standard-dose/pulse-dose crizotinib for 15months; durable (over 7 months) complete remission was achieved with stereotactic radiotherapy and ceritinib. Manipulating the crizotinib schedule in ALK+ NSCLC patients with CNS metastases and using a novel ALK-inhibitor at the time of further progression may provide durable CNS control and allow brain radiotherapy to be deferred.

    RTKs (receptor tyrosine kinases) play important roles in cellular proliferation and differentiation. In addition, RTKs reveal oncogenic potential when their kinase activities are constitutively enhanced by point mutation, amplification or rearrangement of the corresponding genes. The ALK (anaplastic lymphoma kinase) RTK was originally identified as a member of the insulin receptor subfamily of RTKs that acquires transforming capability when truncated and fused to NPM (nucleophosmin) in the t(2;5) chromosomal rearrangement associated with ALCL (anaplastic large cell lymphoma). To date, many chromosomal rearrangements leading to enhanced ALK activity have been described and are implicated in a number of cancer types. Recent reports of the EML4 (echinoderm microtubule-associated protein like 4)–ALK oncoprotein in NSCLC (non-small cell lung cancer), together with the identification of activating point mutations in neuroblastoma, have highlighted ALK as a significant player and target for drug development in cancer. In the present review we address the role of ALK in development and disease and discuss implications for the future. PMID:19459784

    Ependymomas can relapse at the primary site and disseminate to the spinal cord. Furthermore, extraneural metastases are rare. We present a case of anaplastic ependymoma with extraneural metastasis, possibly caused by surgical seeding. An 18-year-old female was referred to us after experiencing frequent convulsive attacks. At age 9 years, she underwent partial resection of a left frontal anaplastic ependymoma, followed by 45 Gy radiation. At age 15 years, a recurrent tumor was totally removed. Three years later, magnetic resonance images revealed a left frontal recurrent tumor and a new parietal lesion. Our preoperative diagnosis of the parietal tumor was a radiation-induced meningioma. However, intraoperative pathological examinations revealed the lesion to be an anaplastic ependymoma. The tumor, which was located in the epidural space and had invaded extensively into the cranial bone, was gross totally removed. Although extremely rare, surgical seeding of anaplastic ependymomas should be considered as a differential diagnosis for recurrent tumors in the surgical field.

    Anaplastic glioma (AG) is divided into three morphology-based groups (anaplastic astrocytoma, anaplastic oligodendroglioma, anaplastic oligoastrocytoma) as well as three molecular groups (glioma-CpG island methylation phenotype [G-CIMP] negative, G-CIMP positive non-1p19q codeleted tumors and G-CIMP positive codeleted tumors). The RTOG 9402 and EORTC 26951 trials established radiotherapy plus (procarbazine, lomustine, vincristine) chemotherapy as the standard of care in 1p/19q codeleted AG. Uni- or non-codeleted AG are currently best treated with radiotherapy only or alkylator-based chemotherapy only as determined by the NOA-04 trial. Maturation of NOA-04 and results of the currently accruing studies, CODEL (for codeleted AG) and CATNON (for uni or non-codeleted AG), will likely refine current up-front treatment recommendations for AG.

    Monoclonal antibody therapy is a new innovation in cancer therapy. Binding of monoclonal antibodies to tumor cells facilitates their destruction by the immune system. Tumor cells with mutated target antigens may escape detection by monoclonal antibodies and exhibit a selective growth advantage. This phenomenon was first recognized in CD20-negative B-cell lymphomas in patients previously treated with the anti-CD20 monoclonal antibody rituximab. We report a cutaneous recurrence of systemic ALCL with an anomalous CD30-negative immunophenotype. The patient had been previously treated with the anti-CD30 monoclonal antibody brentuximab. To our knowledge, we present the first reported case of a cutaneous recurrence of systemic ALCL with an anomalous CD30-negative immunophenotype following chronic brentuximab therapy.

    Anaplastic (giant cell) thyroid carcinoma (ATC), is one of the most aggressive malignancies in humans with a median survival time after diagnosis of 3-6 months. Death from ATC was earlier seen because of local growth and suffocation. ATC is uncommon, accounting for less than 5 % of all thyroid carcinomas. The diagnosis can be established by means of multiple fine needle aspiration biopsies, which are neither harmful nor troublesome for the patient. The cytological diagnosis of this high-grade malignant tumour is usually not difficult for a well trained cytologist. The intention to treat patients with ATC is cure, although only few of them survive. The majority of the patients are older than 60 years and treatment must be influenced by their high age. We have by using a combined modality regimen succeeded in achieving local control in most patients. Every effort should be made to control the primary tumour and thereby improve the quality of remaining life and it is important for patients, relatives and the personnel to know that cure is not impossible. Different treatment combinations have been used since 30 years including radiotherapy, cytostatic drugs and surgery, when feasible. In our latest combined regimen, 22 patients were treated with hyper fractionated radiotherapy 1.6Gy x 2 to a total target dose of 46 Gy given preoperatively, 20 mg doxorubicin was administered intravenously once weekly and surgery was carried out 2-3 weeks after the radiotherapy. 17 of these 22 patients were operated upon and none of these 17 patients got a local recurrence. In the future we are awaiting the development of new therapeutic approaches to this aggressive type of carcinoma. Inhibitors of angiogenesis might be useful. Combretastatin has displayed cytotoxicity against ATC cell lines and has had a positive effect on ATC in a patient. Sodium iodide symporter (NIS) genetherapy is also being currently considered for dedifferentiated thyroid carcinomas with the ultimate aim of

    As part of the National Institute for Health and Care Excellence (NICE) single technology appraisal process, the manufacturer of crizotinib submitted evidence on the clinical and cost effectiveness of crizotinib in untreated anaplastic lymphoma kinase-positive (ALK-positive) non-small-cell lung cancer (NSCLC). Crizotinib has previously been assessed by NICE for patients with previously treated ALK-positive NSCLC (TA 296). It was not approved in this previous appraisal, but had been made available through the cancer drugs fund. As part of this new appraisal, the company included a price discount patient access scheme (PAS). The Centre for Reviews and Dissemination and Centre for Health Economics Technology Appraisal Group at the University of York was commissioned to act as the independent Evidence Review Group (ERG). This article provides a description of the company's submission and the ERG's review and summarises the resulting NICE guidance issued in August 2016. The main clinical-effectiveness data were derived from a multicentre randomised controlled trial-PROFILE 1014-that compared crizotinib with pemetrexed chemotherapy in combination with carboplatin or cisplatin in patients with untreated non-squamous ALK-positive NSCLC. In the trial, crizotinib demonstrated improvements in progression-free survival (PFS) and overall survival (OS). The company's economic model was a three-state 'area under the curve' Markov model. The base-case incremental cost-effectiveness ratio (ICER) was estimated to be greater than £50,000 per quality-adjusted life-year (QALY) gained (excluding the PAS discount). The ERG assessment of the evidence submitted by the company raised a number of concerns. In terms of the clinical evidence, the OS benefit was highly uncertain due to the cross-over permitted in the trial and the immaturity of the data; only 26% of events had occurred by the data cut-off point. In the economic modelling, the most significant concerns related to the analysis

    We present a rare extramedullary ependymoma with diffuse spinal metastatic disease, and review the previous reports of extramedullary spinal ependymomas. Ependymomas are the most common intramedullary spinal cord tumor in adults. These tumors rarely present as extramedullary masses. We treated a 23-year-old man with a history of progressive neck, shoulder and arm pain, with sensory and motor symptoms in the C7 dermatome. MRI of the cervical spine demonstrated a ventral contrast-enhancing lesion with evidence of enhancement along the dura and spinal cord of the upper cervical spine, thoracic spine, and cauda equina. He underwent a tumor debulking procedure without complications. Following surgery, he received craniospinal radiation to treat the remaining tumor and diffuse leptomeningeal disease. The final pathology of the tumor revealed that is was a World Health Organization Grade III anaplastic ependymoma. At the 1 year follow-up, the patient had stable imaging and had returned to his preoperative functional status. Of the 19 reported patients with primary intradural, extramedullary spinal ependymomas, two had extradural components and seven had anaplastic grades. Only one tumor with an anaplastic grade resulted in metastatic disease, but without spinal recurrence. To our knowledge, this is the first report of an intradural, extramedullary spinal ependymoma with an anaplastic grade, presenting with concomitant diffuse, nodular leptomeningeal metastasis involving the upper cervical spine, thoracic spine, conus medullaris, and cauda equina. Similar to the treatment of intramedullary ependymomas with metastasis, this patient underwent an aggressive debulking procedure followed by radiation therapy to the entire neuroaxis.

    Ependymoma is a relatively rare malignancy accounting for 2.0% of all primary central nervous system tumors in adults. Extracranial metastasis is a very uncommon complication of gliomas, especially of anaplastic ependymomas. The objective of this paper is to show that ependymomas can metastasize to soft tissue and lymph nodes as well as to share our approach to this challenge. We report a male patient with anaplastic ependymoma that recurred, metastasizing to the neck and lymph nodes. Metastatic disease was diagnosed based on clinical presentation of a palpable nodule on the right neck and diffuse cervical lymphadenopathies. A biopsy was obtained and pathology revealed anaplastic ependymoma. Whole-body fluorodeoxyglucose positron emission tomography scan showed metastatic disease in the right mastoid region with diffuse uptake in the cervical lymph nodes. Clinical and radiologic response was achieved after three chemotherapy cycles of etoposide, cisplatin, vincristine, and cyclophosphamide. This case highlights extracranial metastasis to the soft tissue as an atypical presentation of recurrent anaplastic ependymoma. Other reported instances of extracranial metastatic ependymoma with this presentation are discussed. The possible metastatic pathways of intracranial disease are discussed. It also illustrates how extracranial disease remains stable with systemic chemotherapy.

    Anaplastic lymphoma kinase (ALK) status analysis of lung cytological specimens should be successfully encouraged in routine practice because biopsy specimens are not always available. To date, the US Food and Drug Administration has approved both fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) as diagnostic tests for identifying ALK-positive patients eligible for treatment with crizotinib. Although ALK IHC is an optimal diagnostic tool, FISH becomes mandatory in equivocal cases. ALK FISH of paraffin-embedded tissue material is still the gold standard, whereas the cytological specimen assay has not yet been completely standardized. Many controversial data have been reported on the adequacy of cytology cell blocks (CBs) versus conventional smears for FISH testing. This review discusses some critical issues related to ALK FISH of cytological samples, including the triaging of collected specimens to optimize the material, the use of CBs versus conventional smears, and alternative methods for an ALK rearrangement diagnosis. Conventional smears have the advantages of an immediate evaluation, no probe tissue-related artifactual loss, no fixation-related alterations, and usually sufficient material for an analytic preparation. On the other hand, CBs have several advantages, including the appropriate conservation of the tissue architecture, an absence of problems related to cell overlapping, and the ability to evaluate neoplastic cells in a dark field.

    Alemtuzumab is a humanized mouse antibody targeting the CD52 cell surface, which has been effective in patients with advanced stage mycosis fungoides (MF) including erythrodermic MF and Sézary syndrome. There are a few descriptions of large cell transformation after its administration. A young patient with an acute onset of Sézary syndrome treated initially unsuccessfully with fludarabine and cyclophosphamide and later on successfully with alemtuzumab has been described. Three weeks after the beginning of therapy, however, she developed transformed T-cell lymphoma indistinguishable from CD30 anaplastic large-cell lymphoma. After bone marrow transplantation, the transformed CD30 cutaneous T-cell lymphoma recurred as a transformed CD30 plaque MF. All 3 types of lesions showed the same T-cell receptor clonal gene rearrangement, which supports the notion that Sézary syndrome, CD30 anaplastic large-cell lymphoma, and MF are interrelated.

    The anaplastic lymphoma kinase (ALK) gene has been found either rearranged or mutated in several neoplasms such as anaplastic large-cell lymphoma, non-small-cell lung cancer, neuroblastoma and anaplastic thyroid cancer. Medulloblastoma (MB) is an embryonic pediatric cancer arising from nervous system, a tissue in which ALK is expressed during embryonic development. We performed an ALK mutation screening in 52 MBs and we found a novel heterozygous germline deletion of a single base in exon 23 (3605delG) in a case with marked anaplasia. This G deletion results in a frameshift mutation producing a premature stop codon in exon 25 of ALK tyrosine kinase domain. We also screened three human MB cell lines without finding any mutation of ALK gene. Quantitative expression analysis of 16 out of 52 samples showed overexpression of ALK mRNA in three MBs. In the present study, we report the first mutation of ALK found in MB. Moreover, a deletion of ALK gene producing a stop codon has not been detected in human tumors up to now. Further investigations are now required to elucidate whether the truncated form of ALK may have a role in signal transduction.

    Anaplastic ependymoma, World Health Organization grade III, is a malignant glioma with ependymal differentiation characterized by high mitotic activity often accompanied by microvascular proliferation and necrosis, where, generally, much fewer ependymal rosettes are found than in ependymoma, World Health Organization grade II. Ependymal rosettes, forming a single layer of tumor cells, differ from ependymoblastic multilayered rosettes, which are characteristic histologic features of ependymoblastoma, a variant of central nervous system primitive neuroectodermal tumor. Here, we report an autopsy case involving a 24-year-old woman with a frontal lobe tumor, which showed the aggregation of true rosettes with multilayering of tumor cells resembling the ependymoblastoma histology. Molecular and cytogenetic analyses revealed the absence of 19q13.42 amplification, a specific molecular hallmark of ependymoblastoma and embryonal tumor with abundant neuropil and true rosettes, supporting the diagnosis of anaplastic ependymoma.

    Introduction: Primary central nervous system lymphoma (PCNSL) of T-cell origin is an exceptionally rare, highly malignant intracranial neoplasm. Although such a tumor typically presents with a focal mass lesion. Case report: Past medical history of a 26-year-old male patient with a PCNS lymphoma of T-cell origin was not suggestive of intracranial pathology or any disorder of other organs and organic systems. To achieve a gross total tumor resection, surgery was performed via osteoplastic craniotomy using the left frontal transcortical transventricular approach. Histological and immunohistochemical analyses of the tissue removed described tumor as anaplastic large cell lymphoma of T-cells (T-ALCL). Postoperative and neurological recovery was complete, while control imaging of the brain showed no signs of residual tumor at a six-month follow-up. The patient, who did not appear immunocompromized, was referred to a hematologist and an oncologist where corticosteroids, the particular chemotherapeutic protocol and irradiation therapy were applied. Conclusion: Since PCNS lymphoma is a potentially curable brain tumor, we believe that proper selection of the management options, including early radical tumor resection for solitary PCNS lymphoma, may be proposed as a major treatment of such a tumor in selected patients, resulting in a satisfactory outcome.

    Anaplastic seminoma constitutes approximately 17% of total experience with seminoma at Memorial Sloan-Kettering Cancer Center. Among 25 previously untreated patients, 11 (44%) were clinical Stage I, and 14 (56%) were clinical Stage II or III. Treatment of these 25 patients with the same regimens employed for classical seminoma yielded an overall 80% 5-year apparent cure rate. Survival rates were poor in eight previously treated patients referred with recurrence.

    The rarity of hemangiopericytoma (HPC) and its controversial histological classification result in its frequent misdiagnosis and thus make the treatment quite challenging. It is often difficult to distinguish these tumors from meningiomas based on clinical features and radiological findings. This is a case report of a man, diagnosed clinically and radiologically as meningioma, which turned out to be anaplastic HPC on histological examination. A 30-year-old man presented with 3 months of progressively worsening of headache and blurring of vision. Clinical examination revealed the right homonymous hemianopia with reduced visual acuity and papilledema bilaterally. Magnetic resonance imaging revealed a multilobulated and heterogenous extraaxial lesion attached to the occipital falx. It measured 9.0 cm (AP) × 5.5 cm (W) × 5.8 cm (CC) and expands bilaterally with major bulk on the left. An occipital craniotomy followed by a subtotal tumor excision was only achieved due to profuse bleeding intraoperatively. Histopathology confirmed an anaplastic HPC (WHO Grade 3). The importance of differentiation between HPCs and meningiomas cannot be overemphasized. A preoperative correct diagnosis is difficult, but it is important that it should be made. Multilobulated (mushroom appearance), prominent internal signal voids, relatively narrow dural attachment, and lytic destruction without calcifications are useful findings to distinguish HPCs from meningiomas.

    Anaplastic lymphoma kinase (ALK), a receptor tyrosine kinase in the insulin receptor superfamily, was initially identified in constitutively activated oncogenic fusion forms – the most common being nucleophosmin-ALK – in anaplastic large-cell lymphomas, and subsequent studies have identified ALK fusions in diffuse large B-cell lymphomas, systemic histiocytosis, inflammatory myofibroblastic tumors, esophageal squamous cell carcinomas and non-small-cell lung carcinomas. More recently, genomic DNA amplification and protein overexpression, as well as activating point mutations, of ALK have been described in neuroblastomas. In addition to those cancers for which a causative role for aberrant ALK activity is well validated, more circumstantial links implicate the full-length, normal ALK receptor in the genesis of other malignancies – including glioblastoma and breast cancer – via a mechanism of receptor activation involving autocrine and/or paracrine growth loops with the reported ALK ligands, pleiotrophin and midkine. This review summarizes normal ALK biology, the confirmed and putative roles of ALK in the development of human cancers and efforts to target ALK using small-molecule kinase inhibitors. PMID:19275511

    Anaplastic thyroid cancer (ATC), accounting for less than 2% of all thyroid cancer, is responsible for the majority of death from all thyroid malignancies and has a median survival of 6 months. The resistance of ATC to conventional thyroid cancer therapies, including radioiodine and thyroid-stimulating hormone suppression, contributes to the very poor prognosis of this malignancy. This review will cover several cellular signaling pathways and mechanisms, including RET/PTC, RAS, BRAF, Notch, p53, and histone deacetylase, which are identified to play roles in the transformation and dedifferentiation process, and therapies that target these pathways. Lastly, novel approaches and agents involving the Notch1 pathway, nuclear factor κB, Trk-fused gene, cancer stem-like cells, mitochondrial mutation, and tumor immune microenvironment are discussed. With a better understanding of the biological process and treatment modality, the hope is to improve ATC outcome in the future. PMID:25260367

    A case of anaplastic ependymoma of the cerebral hemisphere in which the histopathological features closely simulated those of glioblastoma is reported. The patient was a 72-year-old woman with a large, well-demarcated tumor in the left temporal lobe. The tumor was totally extirpated, but recurred 18 months later, and the patient died after 4 months. The extirpated tumor was well circumscribed from the surrounding brain tissue and consisted of a sheet-like, dense proliferation of atypical, short spindle or polygonal cells. Extensive geographic necrosis with nuclear pseudopalisading was seen. Although perivascular pseudorosettes were observed in many areas, true ependymal rosettes were absent. Immunohistochemistry for glial fibrillary acidic protein and epithelial membrane antigen and ultrastructural study confirmed the ependymal nature of tumor cells. The histopathological spectrum of anaplastic ependymoma is very wide and reflects the basically dual characteristics of ependymal cells: epithelial and glial phenotypes. The present case indicates that some anaplastic ependymomas strongly express the glial phenotype and also show remarkable anaplastic cytological features, thus closely simulating glioblastoma. The diagnostic criteria for anaplastic ependymoma, and the nosological position of highly anaplastic ependymoma and its possible clinical implications, are briefly discussed.

    Most cases of anaplastic thyroid carcinoma can be pathologically and often historically associated with the presence of low-grade (differentiated) cancer in the thyroid. That radiation therapy to the differentiated tumor plays an etiologic role in the transformation of a differentiated to an undifferentiated tumor has been suggested. If such therapy can be implicated, is there a difference in risk between external radiotherapy or radioactive iodine? Review of the literature discloses that more anaplastic carcinoma of the thyroid develop in patients without a history of prior radiation than in individuals who have received radiation. We report our recent experience with two patients who demonstrated the sequence of well-differentiated followed by anaplastic thyroid cancer subsequent to radiation and review the question.

    Driver mutations were reported to upregulate programmed death-ligand 1 (PD-L1) expression. However, how PD-L1 expression and immune function was affected by ALK-TKIs and anti-PD-1/PD-L1 treatment in ALK positive non-small-cell lung cancer (NSCLC) remains poorly understood. In the present study, western-blot, real-time PCR, flow cytometry and immunofluorescence were employed to explore how PD-L1 was regulated by ALK fusion protein. ALK-TKIs and relevant inhibitors were used to identify the downstream signaling pathways involved in PD-L1 regulation. Cell apoptosis, viability and Elisa test were used to study the immune suppression by ALK activation and immune reactivation by ALK-TKIs and/or PD-1 blocking in tumor cells and DC-CIK cells co-culture system. We found that PD-L1 expression was associated with EGFR mutations and ALK fusion genes in NSCLC cell lines. Over-expression of ALK fusion protein increased PD-L1 expression. PD-L1 mediated by ALK fusion protein increased the apoptosis of T cells in tumor cells and DC-CIK cells co-culture system. Inhibiting ALK by sensitive TKIs could enhance the production of IFNγ. Anti-PD-1 antibody was effective in both crizotinib sensitive and resistant NSCLC cells. Synergistic tumor killing effects were not observed with ALK-TKIs and anti-PD-1 antibody combination in co-culture system. ALK-TKIs not only directly inhibited tumor viability but also indirectly enhanced the antitumor immunity via the downregulation of PD-L1. Anti-PD-1/PD-L1 antibodies could be an optional therapy for crizotinib sensitive, especially crizotinib resistant NSCLC patients with ALK fusion gene. Combination of ALK-TKIs and anti-PD-1/PD-L1 antibodies treatment for ALK positive NSCLC warrants more data before moving into clinical practice.

    According to the current WHO classification anaplastic gliomas comprise pure astrocytomas and oligodendrogliomas and mixed tumors. This review summarizes findings, discusses problems and defines new questions from the phase III trials on anaplastic gliomas. The molecular subgroup analyses of the NOA-04 trial identified three molecular parameters, which predict longer progression-free and overall survival independent from the mode of therapy, radiotherapy or alkylating chemotherapy-. These are 1p/19q codeletion, methylation of the promoter of the O(6)-methylguanyl methyltransferase (MGMT) gene and hot-spot mutations in the isocitrate dehydrogenase 1 (IDH1) gene. The prognostic relevance of these markers is not lower than that of histopathological subclassification but determination is potentially more robust. Therefore, marker profiles should be included into the next WHO brain tumor classification. The current standard of care for first-line treatment in anaplastic gliomas is radiotherapy or chemotherapy. The next steps, e.g. within the international CATNON trial, are to define the role and optimal sequencing of combined modality treatment focusing on radiotherapy and temozolomide. Inclusion in this trial is already based on the WHO grade and the 1p/19q status and not on the histopathological subtype. Furthermore, anaplastic gliomas are an important group of brain tumors for developing future molecular targeted therapies and should therefore be in the main focus of academic and industrial drug development, which aims at improved efficacy and avoiding long-term side-effects.

    In the treatment of echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase positive (ALK+) non-small-cell lung cancer (NSCLC), secondary mutations within the ALK kinase domain have emerged as a major resistance mechanism to both first- and second-generation ALK inhibitors. This report describes the design and synthesis of a series of 2,4-diarylaminopyrimidine-based potent and selective ALK inhibitors culminating in identification of the investigational clinical candidate brigatinib. A unique structural feature of brigatinib is a phosphine oxide, an overlooked but novel hydrogen-bond acceptor that drives potency and selectivity in addition to favorable ADME properties. Brigatinib displayed low nanomolar IC50s against native ALK and all tested clinically relevant ALK mutants in both enzyme-based biochemical and cell-based viability assays and demonstrated efficacy in multiple ALK+ xenografts in mice, including Karpas-299 (anaplastic large-cell lymphomas [ALCL]) and H3122 (NSCLC). Brigatinib represents the most clinically advanced phosphine oxide-containing drug candidate to date and is currently being evaluated in a global phase 2 registration trial.

    Lung large cell neuroendocrine carcinoma (L-LCNEC) is a rare, aggressive, and difficult-to-treat tumor. It is classified as a neuroendocrine subtype of large cell lung carcinoma (LCLC) belonging to the non-small cell lung cancer (NSCLC) group, but it is also included in the neuroendocrine tumor (NET) group. Most of the available data related to its treatment derive from retrospective analyses or small case series. For patients with L-LCNEC, prognosis is generally very poor. In early stages (I-II-III), surgery is recommended but does not seem to be sufficient. Platinum-based adjuvant chemotherapy may be useful while the role of neoadjuvant chemotherapy is still not well defined. In patients with advanced L-LCNEC, the chemotherapy regimens used in SCLC still remain the standard of treatment, but results are not satisfactory. Due to their peculiar clinical and biological features and the lack of literature data, there is an emerging need for a consensus on the best treatment strategy for L-LCNEC and for the identification of new therapeutic options. In this review, we will discuss the key aspects of L-LCNEC management with the aim to clarify the most controversial issues.

Amongst the various morphologic subtypes, anaplastic CCSK is associated with worse prognosis. Here, we report a case of this rare variant of CCSK. A five-year-old boy presented with history of lump and pain in abdomen since one week. The Computed Tomography (CT) scan revealed a large mass occupying the middle and inferior pole of right kidney. The clinical impression was Wilms tumour. Nephrectomy specimen was received and the diagnosis of CCSK anaplastic variant was offered only after excluding the differentials and after performing ancillary tests such as Immunohistochemistry (IHC). Thus, this case emphasizes the diagnostic challenges on morphology and the essential role of IHC in arriving at a definitive diagnosis, because failure to do so may deprive the child from optimal treatment.

    Low-level laser therapy (LLLT) is a non-thermal phototherapy used in several medical applications, including wound healing, reduction of pain and amelioration of oral mucositis. Nevertheless, the effects of LLLT upon cancer or dysplastic cells have been so far poorly studied. Here we report that the effects of laser irradiation on anaplastic thyroid cancer cells leads to hyperplasia. 650nm of laser diode was performed with a different time interval (0, 15, 30, 60J/cm2 , 25mW) on anaplastic thyroid cancer cell line FRO in vivo. FRO was orthotopically injected into the thyroid gland of nude mice and the irradiation was performed with the same method described previously. After irradiation, the xenograft evaluation was followed for one month. The thyroid tissues from sacrificed mice were undergone to H&E staining and immunohistochemical staining with HIF-1α, Akt, TGF-β1. We found the aggressive proliferation of FRO on thyroid gland with dose dependent. In case of 60 J/ cm2 of energy density, the necrotic bodies were found in a center of the thyroid. The phosphorylation of HIF-1α and Akt was detected in the thyroid gland, which explained the survival signaling of anaplastic cancer cell was turned on the thyroid gland. Furthermore, TGF-β1 expression was decreased after irradiation. In this study, we demonstrated that insufficient energy density irradiation occurred the decreasing of TGF-β1 which corresponding to the phosphorylation of Akt/ HIF-1α. This aggressive proliferation resulted to the hypoxic condition of tissue for angiogenesis. We suggest that LLLT may influence to cancer aggressiveness associated with a decrease in TGF-β1 and increase in Akt/HIF-1α.

    Aims Anaplastic thyroid cancer (ATC) is one of the most aggressive human cancers. Key signal transduction pathways that regulate mitochondrial metabolism are frequently altered in ATC. Our goal was to determine the mitochondrial metabolic phenotype of ATC by studying markers of mitochondrial metabolism, specifically Monocarboxylate Transporter 1 (MCT1) and Translocase of the Outer Mitochondrial Membrane Member 20 (TOMM20). Methods Staining patterns of MCT1 and TOMM20 in 35 human thyroid samples (15 ATC, 12 papillary thyroid cancer (PTC), and 8 non-cancerous thyroid) and 9 ATC mouse orthotopic xenografts were assessed by visual and Aperio digital scoring. Staining patterns of areas involved with cancer versus areas with no evidence of cancer were evaluated independently where available. Results MCT1 is highly expressed in human anaplastic thyroid cancer when compared to both non-cancerous thyroid tissues and papillary thyroid cancers (p<0.001 for both). TOMM20 is also highly expressed in both ATC and PTC compared to non-cancerous thyroid tissue (p<0.01 for both). High MCT1 and TOMM20 expression is also found in ATC mouse xenograft tumors compared to non-cancerous thyroid tissue (p<0.001). These xenograft tumors have high 13C- pyruvate uptake. Conclusions Anaplastic thyroid cancer has metabolic features that distinguish it from PTC and non-cancerous thyroid tissue, including high expression of MCT1 and TOMM20. PTC has low expression of MCT1 and non-cancerous thyroid tissue has low expression of both MCT1 and TOMM20. This work suggests that MCT1 blockade may specifically target ATC cells presenting an opportunity for a new drug target. PMID:26615136

    An 8-yr-old female slender-tailed meerkat (Suricata suricatta) presented with a necrotic sublingual mass and osteolysis of the mandible. After 1 mo of palliative care, the meerkat was euthanized. The mass was diagnosed histologically as an anaplastic carcinoma with extensive rostral mandibular destruction. Immunohistochemistry for vimentin and cytokeratin was validated in this nontypical species and showed that neoplastic cells expressed both mesenchymal and epithelial characteristics, suggestive of a primitive and poorly differentiated tumor. A review of 150 adult slender-tailed meerkat histopathology reports showed a 2% prevalence of orofacial neoplasia, suggesting that oral neoplasms are uncommon in meerkats.

    A total of 114 patients with bronchogenic small cell anaplastic carcinoma and staged as having regional disease all underwent combination chemotherapy consisting of CCNU, cyclophosphamide, and methotrexate. They were randomized to receive either radiotherapy to the primary tumor and regional lymph nodes (4000 rad) or extensive radiotherapy, which included the brain, adrenals, and upper retroperitoneal lymph nodes. Fifteen patients were free of disease after 18 months of chemotherapy and the treatment was discontinued. Only 3 patients subsequently relapsed. No difference was observed between the two groups of patients in median survival time, response rate, duration of response, or relapse pattern, including the frequency of brain metastasis.

    The benefit of postoperative chemotherapy for anaplastic ependymoma remains unknown. We report two pediatric patients with refractory anaplastic ependymoma treated with temozolomide (TMZ). We did not detect O(6) -methylguanine-DNA methyltransferase (MGMT) promoter methylation in tumor samples; however, MGMT protein expression was low. With TMZ treatment, one patient had a 7-month complete remission; the other, stable disease for 15 months. Three other patients did not respond to TMZ; two had high and one low MGMT expression, and two showed no MGMT promoter methylation. These findings suggest that TMZ may be effective for pediatric refractory anaplastic ependymoma with low MGMT protein expression.

    The objective of our study is to determine the influence of race on overall survival (OS) for anaplastic oligodendroglioma (AO). Data were extracted from the National Cancer Data Base (NCDB). Chi-square test, Kaplan-Meier method, and Cox regression models were employed in SPSS 22.0 (Armonk, NY: IBM Corp.) for data analyses. 1643 patients with AO were identified. 1386 (84.3%) were White, 83 (5.0%) Black, 133 (8.1%) Hispanic, and 41 (2.5%) were Asian. White and Black patients were significantly older than Hispanic and Asian patients (49.3% vs. 49.4% vs. 33.1% vs. 39.0%, p=0.003). Black patients were significantly less likely to be insured than White patients (12.8 vs. 7.2%, p<0.001) and significantly more likely to have lower income than other races (p<0.001). A trend towards higher comorbidity burden and lower rate of gross total resection was seen in Black patients. Black patients had significantly worse five-year OS compared to White, Hispanic, and Asian patients (40.3% vs. 52.3% vs. 67.8% vs. 67.7%, p=0.028). Of those who received adjuvant chemoRT, Black patients still had significantly worse OS compared to White patients (p=0.021). On multivariate analysis, Black race, older age at diagnosis, and not receiving adjuvant chemoradiotherapy were independent prognostic factors for worse OS in anaplastic oligodendroglioma. Future studies are warranted to help determine predictors for unfavorable molecular status, ways to optimize management of comorbidities, and interventions to help ensure adequate access to medical care for all patients to better care for those who may be at more risk for poorer outcome.

Prof. Pasquale Calapso was asked to chair the Group and Prof. Stefano Pileri to take care of secretarial duties. The aim of the Group is to spread hematopathologic knowledge among young pathologists and to promote activities that can contribute to updating Italian pathologists on topics of both speculative and diagnostic interest. The first Workshop of the S.I.A.P. Hematopathology Group was held at the Palazzo dei Congressi in Bologna, November 20, 1993. About 150 pathologists from all over Italy took part in the meeting, which consisted of two sections devoted to: a) discussion of the boundaries between Hodgkin's disease and non-Hodgkin's lymphomas, and b) a case seminar illustrating the impact of immunohistochemistry in the diagnosis of bone-marrow biopsy. The first section included 5 presentations and a Round Table chaired by Prof. Luciano Fiore-Donati. Below, the contributors to this section summarize the content of their presentations, which were aimed at answering specific questions the Organizers had put to them.

    O-linked N-acetylglucosamine (O-GlcNAc) glycosylation (O-GlcNAcylation), a dynamic post-translational modification of nuclear and cytoplasmic proteins, may have a critical role in the regulation of biological cell processes and human cancer. O-GlcNAcylation is dynamically regulated by O-GlcNAc transferase (OGT) and O-GlcNAc hydrolase (OGA). Accumulating evidence suggests that O-GlcNAcylation is involved in a variety of types of human cancer. However, the exact role of O-GlcNAcylation in tumor pathogenesis or progression remains to be established. Computed tomography scans of patients with anaplastic thyroid carcinoma (ATC) reveal a rapid growth rate and invasion. The present study demonstrated that O-GlcNAcylation accelerates the progression of ATC. The global O-GlcNAc level of intracellular proteins was increased by overexpression of OGT or downregulation of OGA activity with the specific inhibitor Thiamet-G. By contrast, the global O-GlcNAc level was decreased by silencing of OGT. MTT assay indicated that O-GlcNAcylation significantly promotes cell proliferation. Furthermore, O-GlcNAcylation enhanced cellular biological functions, such as colony formation ability, migration and invasion, of ATC cells in vitro. The findings of the present study suggest that O-GlcNAcylation is associated with malignant properties of thyroid cancer, and may be a potential target for the diagnosis and treatment of thyroid cancer.

    Anaplastic thyroid cancer (ATC) is one of the most aggressive human malignancies, with no effective treatment currently available. Previously, we identified agents active against ATC cells, both in vitro and in vivo, using quantitative high-throughput screening of 3282 clinically approved drugs and small molecules. Here, we report that combining two of these active agents, carfilzomib, a second-generation proteasome inhibitor, and CUDC-101, a histone deacetylase and multi-kinase inhibitor, results in increased, synergistic activity in ATC cells. The combination of carfilzomib and CUDC-101 synergistically inhibited cellular proliferation and caused cell death in multiple ATC cell lines harboring various driver mutations observed in human ATC tumors. This increased anti-ATC effect was associated with a synergistically enhanced G2/M cell cycle arrest and increased caspase 3/7 activity induced by the drug combination. Mechanistically, treatment with carfilzomib and CUDC-101 increased p21 expression and poly (ADP-ribose) polymerase protein cleavage. Our results suggest that combining carfilzomib and CUDC-101 would offer an effective therapeutic strategy to treat ATC.

    Anaplastic thyroid cancer (ATC) is one of the most aggressive human malignancies. Currently, there is no standard or effective therapy for ATC. Drug repurposing for cancer treatment is an emerging approach for identifying compounds that may have antineoplastic effects. The aim of this study was to use high-throughput drug library screening to identify and subsequently validate novel therapeutic agents with anticancer effects in ATC. We performed quantitative high-throughput screening (qHTS) in ATC cell lines (SW-1736, 8505C, and C-643), using a compound library of 3282 drugs. qHTS identified 100 compounds that were active in all three ATC cell lines. Proteasome inhibitors were one of the most active drug categories according to enrichment analysis. Of the three proteasome inhibitors screened, a second-generation proteasome inhibitor, carfilzomib, was the most active. Treatment of ATC cells with carfilzomib significantly inhibited cellular proliferation and induced G2/M cell cycle arrest and caspase-dependent apoptosis. Mechanistically, carfilzomib increased expression of p27 (CDKN1B) and decreased expression of the anti-apoptotic protein ATF4. Pretreatment with carfilzomib reduced in vivo metastases (lung, bone, liver, and kidney) and disease progression, and decreased N-cadherin expression. Carfilzomib treatment of mice with established, widely metastatic disease significantly increased their survival, without significant toxicity. Our findings support the use or clinical study of carfilzomib as a therapeutic option in patients with advanced and metastatic ATC.

    Anaplastic thyroid cancer (ATC) is a rare malignancy. While external beam radiation therapy has improved locoregional control, the median survival of ∼ 4 months has not changed in more than half a century due to uncontrolled systemic metastases. The objective of this study was to review the literature in order to identify potential new strategies for treating this highly lethal cancer. PubMed searches were the principal source of articles reviewed. The molecular pathogenesis of ATC includes mutations in BRAF, RAS, catenin (cadherin-associated protein), beta 1, PIK3CA, TP53, AXIN1, PTEN, and APC genes, and chromosomal abnormalities are common. Several microarray studies have identified genes and pathways preferentially affected, and dysregulated microRNA profiles differ from differentiated thyroid cancers. Numerous proteins involving transcription factors, signaling pathways, mitosis, proliferation, cell cycle, apoptosis, adhesion, migration, epigenetics, and protein degradation are affected. A variety of agents have been successful in controlling ATC cell growth both in vitro and in nude mice xenografts. While many of these new compounds are in cancer clinical trials, there are few studies being conducted in ATC. With the recent increased knowledge of the many critical genes and proteins affected in ATC, and the extensive array of targeted therapies being developed for cancer patients, there are new opportunities to design clinical trials based upon tumor molecular profiling and preclinical studies of potentially synergistic combinatorial novel therapies.

    Anaplastic thyroid cancers (ATC) are among the most aggressive human neoplasms with a dire prognosis and a median survival time of few months from the diagnosis. The complete absence of effective therapies for ATC renders the identification of novel therapeutic approaches sorely needed. Chromosomal instability, a feature of all human cancers, is thought to represent a major driving force in thyroid cancer progression and a number of mitotic kinases showing a deregulated expression in malignant thyroid tissues are now held responsible for thyroid tumor aneuploidy. These include the three members of the Aurora family (Aurora-A, Aurora-B, and Aurora-C), serine/threonine kinases that regulate multiple aspects of chromosome segregation and cytokinesis. Over the last few years, several small molecule inhibitors targeting Aurora kinases were developed, which showed promising antitumor effects against a variety of human cancers, including ATC, in preclinical studies. Several of these molecules are now being evaluated in phase I/II clinical trials against advanced solid and hematological malignancies. In the present review we will describe the structure, expression, and mitotic functions of the Aurora kinases, their implications in human cancer progression, with particular regard to ATC, and the effects of their functional inhibition on malignant cell proliferation.

    Purpose Age is a major prognostic factor for malignant gliomas. However, few studies have investigated the management of gliomas in young adults. We determined the role of survival and treatment in young adults with advanced gliomas in a large population from the Chinese Glioma Genome Atlas (CGGA). Methods This study included 726 adults (age ≥ 18) with histologically proven anaplastic glioma or glioblastoma multiforme (GBM). The overall and progression-free survival was determined in young (age < 50) and older groups (age ≥ 50). Results The study included an older group (OP) of 264 patients and a younger group (YP) of 462patients. In the OP group with GBM and anaplastic glioma, patients treated with RT combined with temozolomide (TMZ) manifested significantly longer OS and PFS compared with patients assigned to RT alone (P < 0.05). In contrast, the YP group diagnosed with anaplastic glioma failed to show any survival advantage with RT plus TMZ compared with RT alone. Conclusions We observed no survival benefit in young adults (age < 50) with anaplastic glioma when treated with TMZ combined with RT. Our findings warrant further investigation of younger patients diagnosed with anaplastic glioma treated with radiotherapy plus TMZ chemotherapy. PMID:27590514

    Meningioma is a common adult intracranial tumor, and while several cases are considered benign, a subset is malignant with biologically aggressive behavior and is refractory to current treatment strategies of combined surgery and radiotherapy. Anaplastic meningiomas are quite aggressive and correspond to a World Health Organization (WHO) Grade III tumor. This highly aggressive phenotype mandates the need for more efficacious therapies. Designing rational therapies for treatment will have its foundation in the biologic understanding of involved genes and molecular pathways in these types of tumors. Anaplastic meningiomas (WHO Grade III) can arise from malignant transformation of lower grade (WHO Grade I/II) tumors, however there is an incomplete understanding of specific genetic drivers of malignant transformation in these tumors. Here, the current understanding of anaplastic meningiomas is reviewed in the context of human neuropathologic specimens and small animal models.

    We report the case of a 61-year-old man with supratentorial extraventricular anaplastic ependymoma who presented with repeated intratumoral hemorrhage. The patient was admitted with headache. Computed tomography and magnetic resonance imaging showed an enhancing mass with intratumoral hemorrhage in the right temporal lobe. Gross total resection was performed. The tumor was well demarcated from the brain tissue, and showed no continuity with the ventricular system. Histopathological examination revealed the features of anaplastic ependymoma. Therefore, additional radiation therapy and adjuvant chemotherapy were administered. Ten months later, the tumor recurred with hemorrhage in the spinal canal. This case showed rapid malignant progression and repeated intratumoral hemorrhage within a short period of time, both of which are characteristics of anaplastic ependymomas. Close observation of the central nervous system and adjuvant radiotherapy are mandatory, even if the ependymoma presents with repeated intratumoral hemorrhage.

    Kaposi sarcoma (KS), a vascular tumor caused by infection with human herpesvirus 8 (HHV8), is a systemic disease that can present with cutaneous lesions with or without visceral involvement. Very few cases of KS, most of which were associated with AIDS, have been reported in the adrenal gland. Anaplastic transformation of KS is a rare clinical presentation known as an aggressive disease with local recurrence and metastatic potential. We report here a 47-year-old HIV negative male presented with extra-adrenal symptoms and had an incidentally detected anaplastic adrenal KS exhibited aggressive clinical course. To the best of our knowledge, this is the first case of anaplastic primary adrenal KS without mucocutaneous involvement but subsequently developed other side adrenal metastases in an HIV negative patient.

    Anaplastic ependymomas are rare malignant tumors of the central nervous system. Few studies are available regarding their neuroradiological characteristics. The present study aimed to retrospectively review a series of patients with extraventricular anaplastic ependymoma and to analyze the magnetic resonance imaging (MRI) characteristics to distinguish anaplastic ependymoma from other intracranial tumors. The clinical and pathological images of 11 patients who presented with histologically proven anaplastic ependymoma at Nanfang Hospital (Southern Medical University, Guangzhou, Guangdong, China) between September 2004 and March 2015 were retrospectively reviewed. MRI scans were obtained in all 11 cases. Computed tomography scans were obtained in only 3 cases. In total, 8 tumors were located at the supratentorial parenchyma, and 3 tumors were derived from the cerebellar hemisphere. Images displayed quasi-circular (4/11), irregularly-lobulated (7/11) variable-intensity masses. The masses presented with cysts or necrosis (8/11), hemorrhage (7/11), marked (9/11) or mild (2/11) enhancement, and moderate (4/11), mild (3/11) or absent (4/11) peritumoral edema. The tumors were also frequently closely associated with the lateral ventricle (6/11). Tumors appeared isointense to hypointense on T1-weighted imaging (T1WI) and heterogeneously hyperintense or hypointense on T2WI, demonstrating wreath-like and ring-like characteristics, with intratumoral nodules (3/11) or marked flake-like inhomogeneous (6/11) enhancement on post-contrast MRI. Only 2 solid lesions showed mild enhancement (2/11). Although the MRI features of the extraventricular anaplastic ependymomas varied and were non-specific, these characteristic MRI findings, combined with the locations of the lesions, the age of onset and the short disease course, could be useful in differentiating anaplastic ependymomas from other intracranial neoplasms in the future.

    We describe the first patient, to our knowledge, with anaplastic pleomorphic xanthoastrocytoma (PXA) with spinal leptomeningeal spread at the time of diagnosis and present a review of the literature. PXA is a tumor that typically has an indolent course but occasionally, when anaplastic features are present, behaves in a more aggressive manner. We found that PXA with spinal leptomeningeal spread at the time of diagnosis confers a worse prognosis. Craniospinal imaging should be obtained at time of diagnosis of PXA and the presence of leptomeningeal spread may be indicative of a more aggressive disease process.

    Anaplastic transformation of well-differentiated thyroid carcinomas at distant metastatic sites is a rare condition. Most cases described in the literature have occurred in the thyroid or regional lymph nodes. We report a case of anaplastic transformation of the follicular variant of papillary thyroid carcinoma in mandibular metastases. A 76-year-old female presented with a painful and enlarging mandibular mass. She had been treated in the past for the follicular variant of papillary thyroid carcinoma. A palliative hemi-mandibulectomy was performed. Histology revealed a metastatic papillary thyroid carcinoma, follicular variant, with an unusual finding of solid pleomorphic epithelioid and spindle cell areas, consistent with anaplastic transformation.

    Background Anaplastic thyroid cancer is considered to be one of the most aggressive human malignancies, and the mean survival time after diagnosis is approximately six months, regardless of treatments. This study aimed to examine how EpCAM and its related molecules are involved in the characteristics of anaplastic thyroid carcinoma. Methodology/Principal Findings Two differentiated thyroid cancer cell lines (TPC-1 and FTC-133), and two anaplastic thyroid cancer cell lines (FRO, ACT-1) were analyzed for expression of CD44 standard isoform (CD44s), CD44 variant isoforms, and EpCAM, and human aldehyde dehydrogenase-1 (ALDH1) enzymatic activity using flow cytometry. CD44s expression was higher in TPC-1 and FTC-133 than in the FRO and ACT-1, whereas ALDH1 activities were higher in FRO and ACT-1 than in TPC-1 and FTC-133. An inverse correlation between CD44s expression and ALDH1 activity was observed in all thyroid cancer cell lines. As for the expressions of CD44 variant isoforms, ACT-1 showed higher and FRO showed moderate CD44v6 expressions, whereas either TPC-1 or FTC-133 showed negative CD44v6 expression. EpCAM expressions in FRO and ACT-1 were higher than those in TPC-1 and FTC-133, and EpCAM expressions inversely correlated with those of CD44s. A positive correlation was observed between EpCAM expression and ALDH1 activity in thyroid cancer cell lines. In the RT-PCR analysis, the expression levels of EpCAM, caludin-7 and ALDH1 in FRO and ATC-1 cells were significantly higher than those in TPC-1 and FTC-133 cells. In clinical specimens of thyroid cancers, nuclear expression of EpCAM and high expression of CD44v6 were detected significantly more frequently in anaplastic carcinomas. Conclusions/Significance Our study suggests the possibility that EpCAM, together with CD44v6 and claudin-7 as well as ALDH1, may be involved in the development of the aggressive phenotype of anaplastic thyroid carcinoma. Our findings may suggest a novel therapeutic strategy for treatment

  14. Large-cell Monte Carlo renormalization of irreversible growth processes

    Monte Carlo sampling is applied to a recently formulated direct-cell renormalization method for irreversible, disorderly growth processes. Large-cell Monte Carlo renormalization is carried out for various nonequilibrium problems based on the formulation dealing with relative probabilities. Specifically, the method is demonstrated by application to the 'true' self-avoiding walk and the Eden model of growing animals for d = 2, 3, and 4 and to the invasion percolation problem for d = 2 and 3. The results are asymptotically in agreement with expectations; however, unexpected complications arise, suggesting the possibility of crossovers, and in any case, demonstrating the danger of using small cells alone, because of the very slow convergence as the cell size b is extrapolated to infinity. The difficulty of applying the present method to the diffusion-limited-aggregation model, is commented on.

    Primary non-Hodgkin's lymphoma of the central nervous system (CNS) is a rare disease. Seven patients were seen and treated at the University of Michigan Medical Center between January 1969 and December 1983. All patients had histologically proven diagnoses of large cell lymphoma with clinical and radiologic evidence of involvement limited to the CNS. Five of seven patients received postoperative radiation therapy, two of whom have had apparent local control at 1- and 2-year follow-up. The two patients without postoperative radiation died of local recurrence 2 and 3 months following subtotal resection. These poor results suggest that adjuvant therapy may be required for improved control of this type of extranodal lymphoma.

    Ependymona occasionally occurs outside the ventricular structures, which is called ectopic ependymona (EE), while pure cortex location is uncommon. However, cortical anaplastic ependymoma (CE) is rare, especially in children. There were only four primary CEs, which is located in the superficial cortex, were reported the age of the patient under 12 years old. The present case is a 20-month-old boy presenting with simple partial seizure was treated in our department. Cranial magnetic resonance imaging (MRI) revealed a fronto-parietal lobe mass of more than 50mm in diameter with mixed signal intensity. Total removal of the mass lesion was performed without any neurological deficit. Pathological examination of the excised tumor were consistent with anaplastic ependymoma (AE). The patient had a good recovery after his surgical resection. Radiotherapy and chemotherapy were not taken into account in view of his age, the favorable site and the complete resection. The management of this unusual tumor is summarized in this paper.

    The aims of this paper were to review the literature of Spermatocytic Seminoma (SS) updating its clinico-pathological features and to present a new case of the exceptionally rare variant of this tumor known as anaplastic which only five cases have been reported. Many studies have confirmed that SS is a distinct neoplasm both clinically and pathologically from classical Seminoma and it differs from the latter especially in regard to behavior, characterized by an almost complete inability to metastasize with only very few convincing examples described with metastatic behavior. There is general agreement that orchidectomy is sufficient therapy for SS and that surveillance following surgery is the preferred management option. Surprisingly, the presence of an anaplastic component does not seem to impact on this excellent prognosis. Very different is the case of sarcomatous transformation, for which further therapy after orchiectomy is advisable.

    A 50-year-old man presented to a nearby hospital with high fever and anorexia. An abdominal tumor was detected, and he was referred to our hospital. A pancreatic tumor was detected by computed tomography and abdominal ultrasonography. He had high fever, leukocytosis, and high serum granulocyte colony-stimulating factor (G-CSF). We performed a tumor biopsy and histological examination revealed anaplastic carcinoma of the pancreas. Based on the diagnosis, we initiated chemotherapy using gemcitabine plus S-1. However, the tumor rapidly progressed and he deteriorated and died 123 days after admission. As immunohistochemical study showed positive staining for G-CSF in the tumor cell, we diagnosed the tumor producing G-CSF during autopsy. Anaplastic carcinoma of the pancreas producing G-CSF is very rare, with 10 cases, including ours, reported in the literature.

    An adult female captive pygmy hippopotamus (Choeropsis liberiensis) was diagnosed with an oral anaplastic sarcoma. The tumor was surgically debulked and intralesional chemotherapy with mitomycin C (0.4 mg/cm(3) of tumor) and cisplatin (1 mg/cm(3) of tumor) was administered. Chemotherapeutic treatment proved difficult due to the risks of repeated anesthetics and unknown drug efficacies. Marked proliferation of the mass was observed during estrus, and chemotherapy was repeated as an experimental treatment to slow tumor progression in order for the animal to remain in the species breeding program. Tumor proliferation was detected during the first trimester of pregnancy; however, in the lactation period, the mass became quiescent. No adverse reactions to chemotherapeutic drugs were observed and the animal continues to be monitored for tumor progression. This is the first report of an anaplastic sarcoma and of chemotherapy use in a pygmy hippopotamus and it highlights logistical considerations for treating neoplasia in this species.

    In this study, the combined effect of doxorubicin with cucurbitacin B on survival of anaplastic thyroid carcinoma cells was evaluated. For experiments, 8505C and CAL62 human anaplastic thyroid carcinoma cells were used. Cell viability, the percentage of viable cells, and cytotoxic activity were measured using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, multiplexed cytotoxicity assay, and cytotoxicity assay, respectively. Reactive oxygen species production was measured. In experiments, doxorubicin and cucurbitacin B reduced cell viability in a dose- and time-dependent manner. Cotreatment of doxorubicin and cucurbitacin B, compared with treatment of doxorubicin alone, decreased the percentage of viable cells and increased cytotoxic activity. All of the combination index values were lower than 1.0, suggesting the synergism between doxorubicin and cucurbitacin B in induction of cytotoxicity. In cells treated with both doxorubicin and cucurbitacin B, compared with doxorubicin alone, the protein levels of cleaved poly(adenosine diphosphate-ribose) polymerase and cyclooxygenase 2 and reactive oxygen species production were enhanced. In contrast, the protein levels of B-cell chronic lymphocytic leukemia/lymphoma 2 and survivin and B-cell chronic lymphocytic leukemia/lymphoma 2/B-cell chronic lymphocytic leukemia/lymphoma 2-associated x protein ratio were diminished. The protein levels of Janus kinase 2 and signal transducer and activator of transcription 3 were reduced, while phospho-extracellular signal-regulated kinase 1/2 protein levels were elevated without change in total extracellular signal-regulated kinase 1/2 protein levels. These results suggest that doxorubicin synergizes with cucurbitacin B in induction of cytotoxicity in anaplastic thyroid carcinoma cells. Moreover, synergistic cytotoxicity of doxorubicin with cucurbitacin B is mediated by B-cell chronic lymphocytic leukemia/lymphoma 2 family proteins, survivin, and reactive oxygen

    There are no effective medical treatments for WHO grade III (anaplastic) meningioma. Patients with this high-grade malignancy have a median survival of less than two years. Therapeutics that modulate the mechanisms that inhibit local immune responses in the tumor microenvironment are showing significant and durable clinical responses in patients with treatment refractory high-grade tumors. We examined the immune infiltrate of 291 meningiomas including WHO grade I-III meningiomas using immunohistochemistry and we examined the expression of PD-L1 mRNA by RNAscope in situ hybridization and PD-L1 protein by immunohistochemistry. In meningioma, the tumor infiltrating lymphocytes are predominantly T cells. In anaplastic meningioma, there is a sharp decrease in the number of T cells, including the numbers of CD4+ and CD8+ T cells and cells expressing PD-1 and there is also an increase in the number of FOXP3 expressing immunoregulatory (Treg) cells. PD-L1 expression is increased in anaplastic meningioma – both mRNA and protein. Using patient derived meningioma cell, we confirm that PD-L1 is expressed in meningioma cells themselves, and not solely in infiltrating immune cells. This work indicates that high-grade meningioma harbor an immunosuppressive tumor microenviroment and that increased Treg cells and elevated PD-L1 may contribute to the aggressive phenotype of these tumors.

    A 50-year-old man with continuous hemosputa and large hematoma of left upper lobe contiguous to bilateral emphysematous bullous disease was admitted for surgery to stop hemorrhage and to resect left lung hematoma and multiple bullae. Bullectomy and neodymium yttrium aluminum garnet (Nd-YAG) laser irradiation to bullae of left upper lobe performed successfully with maximum preserved pulmonary function of it. Pathological examination, however, revealed anaplastic carcinoma inside bulla of S(1+2)c with minimal invasion into adhered parietal pleura (p 3). Left upper lobectomy was carried out with complete mediastinal lymph node dissection (ND 2 b). The final pathological diagnosis was large cell carcinoma of left S(1+2)c with the staging pT3N0M0 and stage II. The patient lives actively in daily life more than 7 years without any recurrence. Clinical analysis of Japanese 20 cases of lung carcinoma with initial signs of hemosputa and/or hemoptysis contiguous to emphysematous bullae elucidate following important facts. Hemosputa and hemoptysis play important role for early finding and diagnosis of lung cancer contiguous to bullous disease, especially in patients of early clinical stage with or without computed tomography (CT) exams and promise to better surgical prognosis and survivals as compared with non hemosputa ones.

    We report on the long-term results of a phase II study of pre-irradiation temozolomide followed by concurrent temozolomide and radiotherapy (RT) in patients with newly diagnosed anaplastic oligodendroglioma (AO) and mixed anaplastic oligoastrocytoma. Pre-RT temozolomide was given for up to 6 cycles. RT with concurrent temozolomide was administered to patients with less than a complete radiographic response. Forty eligible patients were entered and 32 completed protocol treatment. With a median follow-up time of 8.7 years (range 1.1-10.1), median progression-free survival (PFS) is 5.8 years (95 % CI 2.0, NR) and median overall survival (OS) has not been reached (5.9, NR). 1p/19q data are available in 37 cases; 23 tumors had codeletion while 14 tumors had no loss or loss of only 1p or 19q (non-codeleted). In codeleted patients, 9 patients have progressed and 4 have died; neither median PFS nor OS have been reached and two patients who received only pre-RT temozolomide and no RT have remained progression-free for over 7 years. 3-year PFS and 6-year OS are 78 % (95 % CI 61-95 %) and 83 % (95 % CI 67-98 %), respectively. Codeleted patients show a trend towards improved 6-year survival when compared to the codeleted procarbazine/CCNU/vincristrine (PCV) and RT cohort in RTOG 9402 (67 %, 95 % CI 55-79 %). For non-codeleted patients, median PFS and OS are 1.3 and 5.8 years, respectively. These updated results suggest that the regimen of dose intense, pre-RT temozolomide followed by concurrent RT/temozolomide has significant activity, particularly in patients with 1p/19q codeleted AOs and MAOs.

    Papillary and rhabdoid meningiomas are pathologically World Health Organization (WHO) grade III. Any correlation between clinical prognosis and pathologic component is not clear. We analyzed the prognoses of patients with meningiomas with a rhabdoid or papillary component compared to those of patients with anaplastic meningiomas. From 1994 to June 2013, 14 anaplastic meningiomas, 6 meningiomas with a rhabdoid component, and 5 meningiomas with papillary component were pathologically diagnosed. We analyzed magnetic resonance imaging (MRI) findings, extent of removal, adjuvant treatment, progression-free survival (PFS), overall survival (OS), and pathologic features of 14 anaplastic meningiomas (group A), 5 meningiomas with a predominant (≥50%) papillary or rhabdoid component (group B1), and 6 meningiomas without a predominant (<50%) rhabdoid or papillary component (group B2). Homogeneous enhancement on MRI was associated with improved PFS compared to heterogeneous enhancement (p=0.025). Depending on pathology, the mean PFS was 134.9±31.6 months for group A, 46.6±13.4 months for group B1, and 118.7±19.2 months for group B2. The mean OS was 138.5±24.6 months for group A and 59.7±16.8 months for group B1. All recurrent tumors were of the previously diagnosed pathology, except for one tumor from group B1, which recurred as an atypical meningioma without a papillary component. Group B1 tumors showed a more aggressive behavior than group B2 tumors. In group B2 cases, the pathologic findings of non-rhabdoid/papillary portion could be considered for further adjuvant treatment. PMID:27446516

    Anaplastic thyroid carcinoma (ATC) is a severe thyroid malignancy with poor prognosis, due to its early metastasis and unresponsiveness to both radiation and chemotherapy. Nevirapine, a non-nucleoside reverse transcriptase inhibitor, has been used as a re-differentiation agent to treat cancers in several human cancer models. So far, the effects of nevirapine on human thyroid anaplastic carcinoma cells have not been documented. The aim of this study was to evaluate the therapeutic potential of nevirapine in treatment of human thyroid anaplastic carcinoma. Cell proliferation was determined by methly thiazolyl tetrazolium (MTT) assay. Cell apoptosis was analyzed by Hoechst 33258 staining. The mRNA expression of NIS and TSHR was determined by real-time quantitative reverse transcription-polymerase chain reaction (real time RT-PCR). Iodine uptake was determined by (125)I radioactivity assay. At all doses (100, 200, 350, 500 μmol/L) tested, nevirapine significantly inhibited cell proliferation after 48 h treatment. At high dose (500 μmol/L), nevirapine significantly increased the percentage of apoptotic cells compared with control (P<0.01). At lower doses (200 μmol/L and 350 μmol/L), nevirapine did not induce cell apoptosis, but up-regulated NIS and THSR mRNA expression in a dose-dependent manner. In FRO cells pre-treated with nevirapine, the increase in NIS expression had no obvious effect on iodine uptake. These findings indicate that nevirapine has an anti-proliferative effect on FRO cells, which correlates with an induction of cell differentiation.

    Tumor cell invasion into the surrounding nervous tissue is one of the histologic hallmarks of anaplastic meningiomas. To identify other possible markers for aggression in canine meningiomas, the relationship between histologic features and the expression of molecules involved in cell adhesion, cell proliferation, and invasion was examined. Immunohistochemistry for epithelial cadherin (E-cadherin), neural cadherin (N-cadherin), β-catenin, doublecortin (DCX), and Ki-67 was performed for 55 cases of canine meningioma. DCX was preferentially expressed in tumor cells invading the brain parenchyma (12 of 14 cases), suggesting its involvement in the invasion process. Regardless of the histologic type, E-cadherin and N-cadherin expression was observed in 31 of 55 and 44 of 55 cases, respectively. There was a significant positive correlation between DCX and N-cadherin expression and a significant negative correlation between E-cadherin and N-cadherin expression, suggesting that decreased E-cadherin and increased N-cadherin expression induce DCX expression. Typical membranous β-catenin expression was observed in 10 of 55 cases, whereas nuclear translocation was observed in 33 cases. Nuclear β-catenin expression was frequently found in anaplastic meningiomas (12 of 14 cases). The Ki-67 labeling indices were significantly higher in anaplastic meningiomas than in other types. These findings indicate that the expression of N-cadherin and DCX and the nuclear translocation of β-catenin are closely associated with the presence of invasion and anaplasia in canine meningiomas. Notably, granular cell meningiomas were negative for almost all the molecules examined, suggesting that they have a different tumor biology than other meningiomas.

    This is the first report in which crizotinib, an anaplastic lymphoma kinase (ALK) inhibitor, reduced an atypical carcinoid tumor with ALK rearrangement. A 70-year-old man developed a tumor in the left lung and multiple metastases to the lung and brain. The pathology of transbronchial biopsied specimens demonstrated an atypical carcinoid pattern. Combined with immunohistochemical findings, we diagnosed the tumor as atypical carcinoid. ALK gene rearrangement was observed by both immunohistochemical (IHC) and fluorescence in situ hybridization. He was treated with chemotherapy as first-line therapy, however, the tumor did not respond to chemotherapy. Thereafter, he was treated with crizotinib, which successfully reduced the tumors.

    Background: Ollier disease is a rare, nonfamilial disorder that primary affects the long bones and cartilage of joints with multiple enchondromas. It is associated with a higher risk of central nervous system (CNS) malignancies; although the incidence is unknown. Case Description: Here, we present the case of a 55-year-old woman who developed an anaplastic astrocytoma with a known diagnosis of Ollier disease with a survival time of over 3 years. Conclusion: This report draws attention to the rarity of this disease and the paucity of information regarding CNS involvement in Ollier disease, as well as reviews the current literature.

    We report the neuroimaging and histopathologic findings of a 12-year-old female patient with a disseminated oligodendroglial-like leptomeningeal tumor with anaplastic progression and presumed extraneural metastatic disease. These tumors may represent distinct pathology primarily seen in pediatric patients. Neuroimaging demonstrates diffuse, progressive enhancement of the leptomeninges often with interval development of intraparenchymal lesions on follow-up. Disease is typically confined to the central nervous system, though diffuse peritoneal disease was seen in our case, possibly through metastatic seeding of the abdomen via ventriculoperitoneal shunt.

    The degrees of invasiveness, proliferative activity, morphofunctional activity of nuclei in the thyroidal gland tumors were studied, while analyzing material, obtained in 1343 patients, suffering thyroidal gland cancer (THGC) and operated on in 2000-2013 yrs. Morphological point quantity of malignancy (as a criterion of the tumor progression grade) and mitotic activity in cellular population were determined in various kinds of THGC. Undifferentiated (anaplastic carcinoma) type of THGC is the most malignant one. There were determined a spindle-like, giant-cell and squamous-cell forms of undifferentiated THGC. The presence of sites of differentiated cancer in 33% of histological preparations witnesses the interrelationship with the earlier existed pathological process.

    The outcome of patients with anaplastic gliomas varies considerably. Whether a molecular classification of anaplastic gliomas based on large-scale genomic or epigenomic analyses is superior to histopathology for reflecting distinct biological groups, predicting outcomes and guiding therapy decisions has yet to be determined. Epigenome-wide DNA methylation analysis, using a platform which also allows the detection of copy-number aberrations, was performed in a cohort of 228 patients with anaplastic gliomas (astrocytomas, oligoastrocytomas, and oligodendrogliomas), including 115 patients of the NOA-04 trial. We further compared these tumors with a group of 55 glioblastomas. Unsupervised clustering of DNA methylation patterns revealed two main groups correlated with IDH status: CpG island methylator phenotype (CIMP) positive (77.5 %) or negative (22.5 %). CIMP(pos) (IDH mutant) tumors showed a further separation based on copy-number status of chromosome arms 1p and 19q. CIMP(neg) (IDH wild type) tumors showed hallmark copy-number alterations of glioblastomas, and clustered together with CIMP(neg) glioblastomas without forming separate groups based on WHO grade. Notably, there was no molecular evidence for a distinct biological entity representing anaplastic oligoastrocytoma. Tumor classification based on CIMP and 1p/19q status was significantly associated with survival, allowing a better prediction of outcome than the current histopathological classification: patients with CIMP(pos) tumors with 1p/19q codeletion (CIMP-codel) had the best prognosis, followed by patients with CIMP(pos) tumors but intact 1p/19q status (CIMP-non-codel). Patients with CIMP(neg) anaplastic gliomas (GBM-like) had the worst prognosis. Collectively, our data suggest that anaplastic gliomas can be grouped by IDH and 1p/19q status into three molecular groups that show clear links to underlying biology and a significant association with clinical outcome in a prospective trial cohort.

    Gangliogliomas are rare tumors of the central nervous system that are thought to arise from a glioneuronal precursor and consist of both neuronal and glial elements. Grade III, or anaplastic ganglioglioma (AGG), most commonly affects children and young adults, generally arises in a supratentorial location, is highly epileptogenic, and often results in diffuse local and distant failure within the craniospinal axis. Pathologically, these tumors are graded by the degree of malignancy in their glial portion and radiologic diagnosis is difficult due to the wide variation in its degree of solid and cystic components, contrast uptake, and calcification patterns. This report presents three cases of AGG, with initial treatment including subtotal resection followed by conformal radio-therapy. In the case where the AGG developed in the setting of an existent low-grade astrocytoma, the patient received no chemotherapy. Both of the other de novo cases were managed with adjuvant chemoradiotherapy with temozolomide. Recurrence occurred at 6, 16, and 20 months following therapy. Two of the three patients experienced symptomatic decline at recurrence, but experienced Karnofsky performance status (KPS) improvement after salvage therapy, including the reduction of cranial neuropathy and balance. All patients had a significant reduction in presenting symptoms following salvage therapy. Patients died at 23, 20, and 22 months following initial surgical management, respectively. A review of anaplastic and malignant gangliogliomas is presented in the context of these three cases. PMID:25862009

    Learning data representations directly from the data itself is an approach that has shown great success in different pattern recognition problems, outperforming state-of-the-art feature extraction schemes for different tasks in computer vision, speech recognition and natural language processing. Representation learning applies unsupervised and supervised machine learning methods to large amounts of data to find building-blocks that better represent the information in it. Digitized histopathology images represents a very good testbed for representation learning since it involves large amounts of high complex, visual data. This paper presents a comparative evaluation of different supervised and unsupervised representation learning architectures to specifically address open questions on what type of learning architectures (deep or shallow), type of learning (unsupervised or supervised) is optimal. In this paper we limit ourselves to addressing these questions in the context of distinguishing between anaplastic and non-anaplastic medulloblastomas from routine haematoxylin and eosin stained images. The unsupervised approaches evaluated were sparse autoencoders and topographic reconstruct independent component analysis, and the supervised approach was convolutional neural networks. Experimental results show that shallow architectures with more neurons are better than deeper architectures without taking into account local space invariances and that topographic constraints provide useful invariant features in scale and rotations for efficient tumor differentiation.

    Anaplastic thyroid cancer (ATC) is a rare but aggressive malignancy of the thyroid. No effective treatment modalities are currently available. Targeted therapy against protein kinases showed promising results in preclinical studies. Our goal was to assess the mutational status of potential therapeutic targets, as well as the biomarker for immunotherapy in the clinical context. Using allele specific PCR, Sanger sequencing, fragment analysis and immunohistochemistry, we assessed BRAF, KRAS, EGFR mutations and protein overexpression of C-KIT and PDL1 in anaplastic thyroid cancer specimens. Results were compared to clinical information and patient outcome to assess the utility of these biomarkers. There were 13 patients in our study with a median overall survival of 19 weeks. Of the 13 ATC patients, 3 (23 %) had BRAF V600E mutation. C-KIT overexpression was found in 1 (8 %) patient who responded well to a tyrosine kinase inhibitor. PDL1 expression was seen in 3 (23 %) patients, none of them were surgical candidates due to unresectability and poor performance status. KRAS codon 12/13 and EGFR exon 18, 19, 20 and 21 were all wild type in our patients. Protein kinase inhibitors and immunotherapy may be useful adjuvant therapies for ATC.

    Anaplastic thyroid carcinoma (ATC) is the most aggressive of thyroid cancers whose treatment is not yet established and mortality is extremely high. Recent in vitro studies have shown that valproic acid (VA), a newly identified histone deacetilase (HDAC) inhibitor, induces apoptosis, modulates differentiation gene expression of thyroid tumors and enhances the sensitivity of anaplastic cancer cell lines to doxorubicin. We report a case of successful treatment of anaplastic thyroid carcinoma with a combination of oral valproic acid, chemotherapy consisting of cisplatin and doxorubicin, external and intra-operative radiation and surgery. Tumor volume decreased by 50.7% under CT measurement and 44.6% under sonogram measurement over the course of the treatment. No significant rebound of tumor size was observed between each cycle of chemotherapy. Serial cytology performed via fine needle aspiration (FNA) presented a rapidly changing profile of cell types, starting with anaplastic and proceeding through increasingly well differentiated presentations. Only microscopic remnants of ATC cells were found in the histological examination of the resected thyroid. Ga scintigraphy and whole body PET scan six months after surgery revealed no evidence of recurrence or metastasis. As of Nov. 22, 2008, the patient is alive and disease free two years after diagnosis.

    Purpose: Anaplastic gliomas represent a heterogeneous group of primary high-grade brain tumors, and the optimal postoperative treatment remains controversial. In this report, we present our institutional data on the clinical outcomes of radiation therapy (RT) plus temozolomide (RT + TMZ) for anaplastic gliomas, stratified by histology and 1p/19q codeletion. Methods and Materials: A single-institution retrospective review was conducted of patients with supratentorial anaplastic oligodendroglioma (AO), mixed anaplastic oligoastrocytoma (AOA), and anaplastic astrocytoma (AA). After surgery, RT was delivered at a median total dose of 60 Gy (range, 31.6-63 Gy) in daily fractions. All patients received standard concurrent TMZ, with or without adjuvant TMZ. Histological/molecular subtypes were defined as codeleted AO/AOA, non-codeleted AO/AOA, and AA. Results: From 2000 to 2012, 111 cases met study criteria and were evaluable. Codeleted AO/AOA had superior overall survival (OS) to non-codeleted AO/AOA (91% vs 68% at 5 years, respectively, P=.02), whereas progression-free survival (PFS) was not significantly different (70% vs 46% at 5 years, respectively, P=.10). AA had inferior OS to non-codeleted AO/AOA (37% vs 68% at 5 years, respectively, P=.007) and inferior PFS (27% vs 46%, respectively, P=.03). On multivariate analysis, age, performance status, and histological or molecular subtype were independent predictors for both PFS and OS. Compared to historical controls, RT + TMZ provided comparable OS to RT with procarbazine, lomustine, and vincristine (RT + PCV) for codeleted AO/AOA, superior OS to RT alone for non-codeleted AO/AOA, and similar OS to RT alone for AA. Conclusions: RT + TMZ may be a promising treatment for both codeleted and non-codeleted AO/AOA, but its role for AA remains unclear.

    Thyroid cancer is an endocrine malignancy with an incidence rate that has been increasing steadily over the past 30 years. While well-differentiated subtypes have a favorable prognosis when treated with surgical resection and radioiodine, undifferentiated subtypes, such as anaplastic thyroid cancer (ATC), are far more aggressive and have a poor prognosis. Conventional therapies (surgical resection, radiation, chemotherapy, and radioiodine) have been utilized for treatment of ATC, yet these treatments have not significantly improved the overall mortality rate. As cancer is a genetic disease, genetic alterations such as mutations, fusions, activation of oncogenes, and silencing of tumor suppressors contribute to its aggressiveness. With the use of next-generation sequencing and the Cancer Genome Atlas, mutation-directed therapy is recognized as the upcoming standard of care. In this review, we highlight the known genetic landscape of ATC and the need for a comprehensive genetic characterization of this disease in order to identify additional therapeutic targets to improve patient outcomes.

    We report a case of a 64-year-old woman with anaplastic carcinoma of the pancreas (ACP) with cyst formation and review 60 ACP cases reported in Japan. In 20% of cases, laboratory tests revealed severe anemia (hemoglobin level < 10.0 g/dL) and elevated leucocyte counts (> 12000/mm3), which were likely attributable to rapid tumor growth, intratumoral hemorrhage, and necrosis. Elevated serum CA19-9 levels were observed in 55% of cases. Cyst-like structures were observed on imaging in 47% of cases, and this finding appears to reflect subsequent cystic degeneration in the lesion. Macroscopically, hemorrhagic necrosis was observed in 77% of cases, and cyst formation was observed in 33% of cases. ACP should be considered when diagnosing pancreatic tumors with a cyst-like appearance, especially in the presence of severe anemia, elevated leucocyte counts, or elevated serum CA19-9 levels.

    Purpose: To analyze a prospective protocol combining surgery, chemotherapy (CT), and hyperfractionated accelerated radiotherapy (RT) in anaplastic thyroid carcinoma. Methods and materials: Thirty anaplastic thyroid carcinoma patients (mean age, 59 years) were treated during 1990-2000. Tumor extended beyond the capsule gland in 26 patients, with tracheal extension in 8. Lymph node metastases were present in 18 patients and lung metastases in 6. Surgery was performed before RT-CT in 20 patients and afterwards in 4. Two cycles of doxorubicin (60 mg/m{sup 2}) and cisplatin (120 mg/m{sup 2}) were delivered before RT and four cycles after RT. RT consisted of two daily fractions of 1.25 Gy, 5 days per week to a total dose of 40 Gy to the cervical lymph node areas and the superior mediastinum. Results: Acute toxicity (World Health Organization criteria) was Grade 3 or 4 pharyngoesophagitis in 10 patients; Grade 4 neutropenia in 21, with infection in 13; and Grade 3 or 4 anemia and thrombopenia in 8 and 4, respectively. At the end of the treatment, a complete local response was observed in 19 patients. With a median follow-up of 45 months (range, 12-78 months), 7 patients were alive in complete remission, of whom 6 had initially received a complete tumor resection. Overall survival rate at 3 years was 27% (95% confidence interval 10-44%) and median survival 10 months. In multivariate analysis, tracheal extension and macroscopic complete tumor resection were significant factors in overall survival. Death was related to local progression in 5% of patients, to distant metastases in 68%, and to both in 27%. Conclusions: Main toxicity was hematologic. High long-term survival was obtained when RT-CT was given after complete surgery. This protocol avoided local tumor progression, and death was mainly caused by distant metastases.

    The aim of this study was to determine the utilization rates and impact of adjuvant therapy on overall survival (OS) for anaplastic oligodendroglioma (AO). Data were extracted from the National Cancer Data Base (NCDB). Chi square test, Kaplan-Meier method, and Cox regression models were employed in SPSS 22.0 (Armonk, NY: IBM Corp.) for data analyses. 1692 patients with AO who underwent surgery were identified. 945 (55.9 %) received adjuvant radiotherapy with concomitant chemotherapy (chemoRT), 102 (6.0 %) adjuvant radiotherapy (RT) sequentially followed by chemotherapy, 244 (14.4 %) adjuvant RT alone, and 401 (23.7 %) received no adjuvant therapy. Patients were more likely to receive adjuvant chemoRT if they were diagnosed in 2009-2013 vs. 2004-2008 (p < 0.001), had Karnofsky Performance Status >70 vs. <70 (p = 0.018), had private insurance vs. Medicaid vs. no insurance (p < 0.001), or had median income ≥$63,000 vs. <$63,000 (p = 0.014). Those who received adjuvant chemoRT (concomitant or sequential) had significantly better 5-year OS than those who received adjuvant RT alone or no adjuvant therapy (59.8 % vs. 65.0 % vs. 44.9 % vs. 45.6 %, p < 0.001). This significant 5-year OS benefit was also observed regardless of age. There was no difference in OS when comparing concomitant chemoRT to sequential RT and chemotherapy (p = 0.481). On multivariate analysis, receipt of adjuvant chemoRT (concomitant or sequential) remained an independent prognostic factor for improved OS. Adjuvant chemoRT (concomitant or sequential) is an independent prognostic factor for improved OS in anaplastic oligodendroglioma and should be considered for all clinically suitable patients who have undergone surgery for the disease.

    The outcome of patients with anaplastic gliomas varies considerably depending on single molecular markers, such as mutations of the isocitrate dehydrogenase (IDH) genes, as well as molecular classifications based on epigenetic or genetic profiles. Remarkably, 98% of the RNA within a cell is not translated into proteins. Of those, especially microRNAs (miRNAs) have been shown not only to have a major influence on physiologic processes but also to be deregulated and prognostic in malignancies.To find novel survival markers and treatment options we performed unbiased DNA methylation screens that revealed 12 putative miRNA promoter regions with differential DNA methylation in anaplastic gliomas. Methylation of these candidate regions was validated in different independent patient cohorts revealing a set of miRNA promoter regions with prognostic relevance across data sets. Of those, miR-155 promoter methylation and miR-155 expression were negatively correlated and especially the methylation showed superior correlation with patient survival compared to established biomarkers.Functional examinations in malignant glioma cells further cemented the relevance of miR-155 for tumor cell viability with transient and stable modifications indicating an onco-miRNA activity. MiR-155 also conferred resistance towards alkylating temozolomide and radiotherapy as consequence of nuclear factor (NF)κB activation.Preconditioning glioma cells with an NFκB inhibitor reduced therapy resistance of miR-155 overexpressing cells. These cells resembled tumors with a low methylation of the miR-155 promoter and thus mir-155 or NFκB inhibition may provide treatment options with a special focus on patients with IDH wild type tumors.

    Acute spontaneous tumor lysis (ASTL) syndrome, an extremely rare disease, requires prompt recognition and aggressive management because it is fulminant at its outset, associated with severe metabolic derangement, and potentially reversible. We describe an unusual case in which spontaneous tumor lysis occurred in anaplastic large T-cell lymphoma associated with acute uric acid nephropathy, persistent oliguria, and shock. This case contrasts markedly with previously reported cases of ASTL syndrome, which developed mainly in the pathologic type of Burkitt lymphoma. To our knowledge, this is the first reported occurrence of ASTL syndrome associated with anaplastic large T-cell type lymphoma. This report also chronicles our successful experience with continuous renal replacement therapy in the presence of compromised hemodynamic status.

    Anaplastic glioma is Grade III and the median overall survival is about 37.6 months. However, there are still other factors that affect the prognosis for anaplastic glioma patients due to variable overall survival. So we screened four-lncRNA signature (AGAP2-AS1, TPT1-AS1, LINC01198 and MIR155HG) from the lncRNA expression profile from the GSE16011, CGGA and REMBRANDT datasets. The patients in low risk group had longer overall survival than high risk group (median OS 2208.25 vs. 591.30 days; P < 0.0001). Moreover, patients in the low risk group showed similar overall survival to Grade II patients (P = 0.1669), while the high risk group showed significant different to Grade IV (P = 0.0005) with similar trend. So based on the four-lncRNA, the anaplastic gliomas could be divided into grade II-like and grade IV-like groups. On the multivariate analysis, it showed the signature was an independent prognostic factor (P = 0.000). The expression of four lncRNAs in different grades showed that AGAP2-AS1, LINC01198 and MIR155HG were increased with tumor grade, while TPT1-AS1 was decreased. Knockdown of AGAP2-AS1 can inhibit the cell proliferation, migration and invasion, while increase the apoptosis cell rates in vitro. In conclusion, our results showed that the four-lncRNA signature has prognostic value for anaplastic glioma. Moreover, clinicians should conduct corresponding therapies to achieve best treatment with less side effects for two groups patients. PMID:27764782

    Anaplastic large cell lymphoma (ALCL) is an aggressive, highly proliferative, T-cell lymphoma with increasing incidence worldwide. Anaplastic Lymphoma Kinase (ALK) fusions occur in about 50% of all cases. Most ALK positive cases of ALCL harbor the t(2;5) translocation that leads to expression of Nucleophosmin-Anaplastic Lymphoma Kinase (NPM-ALK). NPM-ALK induces a variety of oncogenic signaling pathways that lead to malignant transformation of T-cells via Activator Protein-1 (AP-1), STAT3 and other (transcription) factors. In addition to the commonly known AP-1 activators Mitogen-Activated Protein Kinases (MAPKs), there are other signaling pathways, such as PI3K/mTOR/AKT, which are implicated in AP-1 activation/expression in ALCL. The AP-1 factor JUNB was shown to drive ALCL proliferation and the expression of the characteristic ALCL Ki-1 antigen, CD30. cJUN and JUNB target PDGFRB, thereby leading to tumor progression and dissemination. Furthermore, aberrant gene expression in ALCL is frequently accompanied by changes in epigenetic regulatory mechanisms, such as DNA methylation patterns. Here, we discuss the role of AP-1 in the pathogenesis of ALCL and provide an overview of pathological epigenetic changes in ALCL cells.

    Background Anaplastic astrocytomas are progressive brain tumors with a tendency to infiltrate the surrounding tissue. Recurrence is very common, with recurrent tumors being extremely refractory to existing therapies. Case Presentation: A 33-year-old woman presented with a history of an unprovoked fall, followed by seizures. An MRI scan revealed a mass in the fronto-temporo-parietal region of the brain, suggesting a primary tumor. She underwent craniotomy and surgical debulking of the tumor. The histology of the tumor tissue revealed an anaplastic astrocytoma. Follow-up MRI scans indicated the presence of a residual, rapidly progressing tumor. A 6-week course of fractionated radiation and concurrent chemotherapy with Temodar® (temozolomide capsules) did not stop tumor progression. Intervention: Due to the failure of conventional therapies in preventing rapid disease progression, the patient volunteered to undergo a 28-day course of Sequentially Programmed Magnetic Field (SPMF) therapy. Results Immediate post-therapy MRI scan showed a cessation of tumor growth, and follow-up imaging at 6, 12, 24 and 36 months revealed a gradual but steady decrease in the size of the tumor. The patient reported an alleviation of clinical symptoms and a subjective improvement in the quality of life at 6, 12, 24 and 36 months following SPMF therapy. Conclusion The remarkable improvement of this patient suggests that SPMF therapy may be a valuable option for anaplastic astrocytoma, especially in recurrent and rapidly progressing tumors.

    We herein report a case of anaplastic carcinoma of the pancreas with remarkable intraductal tumor growth into the main pancreatic duct. A 76-year-old male was referred to our hospital for treatment of a pancreatic tumor. Preoperative examinations revealed a poorly defined tumor in the main pancreatic duct in the body of the pancreas, accompanied with severe dilatation of the main pancreatic duct, which was diagnosed as an intraductal papillary-mucinous neoplasm. We performed distal pancreatectomy and splenectomy. The pathological examination revealed that the tumor consisted of a mixture of anaplastic carcinoma (giant cell type) and adenocarcinoma in the pancreas. There was a papillary projecting tumor composed of anaplastic carcinoma in the dilated main pancreatic duct. The patient is now receiving chemotherapy because liver metastasis was detected 12 mo after surgery. In this case, we could observe a remarkable intraductal tumor growth into the main pancreatic duct. We also discuss the pathogenesis and characteristics of this rare tumor with specific tumor growth.

    In neuroblastoma (NB), one of the most common paediatric solid tumours, activation of anaplastic lymphoma kinase (ALK) is often associated with poor outcomes. Although genetic studies have identified copy number alteration and nonsynonymous mutations of ALK, the regulatory mechanism of ALK signalling at protein levels is largely elusive. Neuronal leucine-rich repeat 1 (NLRR1) is a type 1 transmembrane protein that is highly expressed in unfavourable NB and potentially influences receptor tyrosine kinase signalling. Here, we showed that NLRR1 and ALK exhibited a mutually exclusive expression pattern in primary NB tissues by immunohistochemistry. Moreover, dorsal root ganglia of Nlrr1+/+ and Nlrr1−/− mice displayed the opposite expression patterns of Nlrr1 and Alk. Of interest, NLRR1 physically interacted with ALK in vitro through its extracellular region. Notably, the NLRR1 ectodomain impaired ALK phosphorylation and proliferation of ALK-mutated NB cells. A newly identified cleavage of the NLRR1 ectodomain also supported NLRR1-mediated ALK signal regulation in trans. Thus, we conclude that NLRR1 appears to be an extracellular negative regulator of ALK signalling in NB and neuronal development. Our findings may be beneficial to comprehend NB heterogeneity and to develop a novel therapy against unfavourable NB. PMID:27604320

    Reports describing a rapid increase in the cystic volume of anaplastic astrocytoma (AA) in a short time frame are rare. The present study reports the case of a 68-year-old male who was admitted to the No. 9 People's Hospital, Shanghai Jiaotong University School of Medicine (Shanghai, China), with a small cystic brain lesion and positive immunological testing for cysticercosis. Head magnetic resonance imaging (MRI) showed a cystic lesion, 6 mm in diameter, in the left frontal lobe. Neurocysticercosis was suspected and the patient was treated with a clinical trial of albendazole and steroids. A period of 25 days later, the patient's condition had deteriorated, and MRI revealed a cystic lesion in the left frontal lobe; thereafter, the cystic lesion was removed and a diagnosis of AA was established. The tumor was soft, ivory white and gelatinous due to myxoid degeneration. In this case, tumor-related angiogenesis and microvascular extravasation (blood-brain barrier disruption) may have been the main cause of the rapid increase in the cystic volume in such a short time frame. The similarity of the glioma and cysticercus antigens may have been the cause of the positive reactions in the cystic fluid. The present study reports the rare occurrence of a rapid increase of cystic volume and potential diagnostic difficulties. PMID:27698865

  10. Therapeutic strategies and mechanisms of drug resistance in Anaplastic Lymphoma Kinase (ALK)-rearranged lung cancer.

    Anaplastic lymphoma kinase (ALK) gene encoding the receptor tyrosine kinase ALK is expressed as a fusion gene in a variety of carcinomas. The expression of ALK is nearly undetectable in adults, and its activation is normally regulated by its ligands, FAM150A/B. However, ALK gene rearrangements result in different ALK fusion proteins that are constitutively expressed via the active promoter of fusion partner genes. ALK fusion proteins dimerize in a ligand-independent manner and lead to the dysregulation of cell proliferation via abnormal constitutive activation of ALK tyrosine kinase. Many ALK tyrosine kinase inhibitors (TKIs) have been developed to date, are three of which are currently in clinical use for the treatment of ALK-rearranged non-small cell lung cancer (NSCLC). ALK TKIs often achieve marked tumor regression in NSCLC patients with ALK rearrangements; however, ALK TKI-resistant tumors inevitably emerge within a few years in most cases. In this review, we summarize diverse ALK TKI resistance mechanisms identified in NSCLC with ALK rearrangements, and review potential therapeutic strategies to overcome ALK TKI resistance in these patients.

    Cell motility is controlled by the dynamic cytoskeleton and its related proteins, such as members of the ezrin/radixin/moesin (ERM) family, which act as signalling molecules inducing cytoskeleton remodelling. Although ERM proteins have been identified as important factors in various malignancies, functional redundancy between these proteins has hindered the dissection of their individual contribution. The aim of the present study was to analyse the functional role of moesin in pancreatic malignancies. Cancer cells of different malignant lesions of human and transgenic mice pancreata were evaluated by immunohistochemistry. For functional analysis, cell growth, adhesion and invasion assays were carried out after transient and stable knock-down of moesin expression in pancreatic cancer cells. In vivo tumourigenicity was determined using orthotopic and metastatic mouse tumour models. We now show that moesin knock-down increases migration, invasion and metastasis and influences extracellular matrix organization of pancreatic cancer. Moesin-regulated migratory activities of pancreatic cancer cells were in part promoted through cellular translocation of beta-catenin, and re-distribution and organization of the cytoskeleton. Analysis of human and different transgenic mouse pancreatic cancers demonstrated that moesin is a phenotypic marker for anaplastic carcinoma, suggesting that this ERM protein plays a specific role in pancreatic carcinogenesis.

    The protein nestin, a neuronal stem cell marker, has been reported to indicate a poor prognosis in various tumours. Anaplastic thyroid cancer (ATC) is one of the most aggressive malignancies in humans, and its molecular background has not been identified. The present study evaluated the expression of nestin and its significance in ATC. Tissue samples from 23 patients with ATC were subjected to immunohistochemical staining and the staining intensity of nestin in the cytoplasm was evaluated. The expression of nestin in the tumour cytoplasm was confirmed in 6 of the 23 tissue samples (26.1%). Between the nestin-positive group (n=6) and the nestin-negative group (n=17), there were no significant differences in the clinicopathological factors of the patients. However, the nestin-positive group exhibited significantly worse prognoses than the nestin-negative group (median survival time, 86.5 vs. 306 days; P<0.01, log-rank test). The multivariate analysis indicated that nestin expression was a prognostic indicator for the ATC patients (hazard ratio, 5.59; 95% confidence interval, 1.63–19.50; P<0.01), which is independent of the known clinical indicators. Nestin expression has the potential to be an independent indicator of a poor prognosis for patients with ATC. PMID:26622582

    Anaplastic thyroid carcinoma (ATC) is an extremely aggressive human malignancy characterized by a marked degree of invasiveness, absense of features of thyroid differentiation and resistance to current medical treatment. It is well known that ATCs are characterized by deregulation of genes related to cell cycle regulation, i.e., cyclin-dependent kinases (CDKs) and endogenous cyclin-dependent kinase inhibitors (CDKIs). Therefore, in the present study, the effect of a novel exogenous cyclin-dependent kinase inhibitor, BP-14, was investigated in three human ATC cell lines. The ATC-derived cell lines FRO, SW1736 and 8505C were treated with BP-14 alone or in combination with the mTOR inhibitor everolimus. In all ATC cell lines, treatment with BP-14 decreased cell viability and, in two of them, BP-14 modified expression of genes involved in epithelial-mesenchymal transition. Thus, our data indicate that BP-14 is a potential new compound effective against ATC. Combined treatment with BP-14 and the mTOR inhibitor everolimus had a strong synergistic effect on cell viability in all three cell lines, suggesting that the combined used of CDK and mTOR inhibitors may be a useful strategy for ATC treatment.

  14. The role of chemotherapy for pure and mixed anaplastic oligodendroglial tumors.

    PubMed

    2009-08-01

    Pure and mixed anaplastic oligodendrogliomas (AO/mixed-AOs) remain terminal primary brain tumors, without a defined optimal initial therapy, and without sufficiently active and tolerable therapies at recurrence/progression (R/P). Very heterogeneous international therapy recommendations remain. Historical advances have resulted in only modest improvements in outcome. AO/mixed-AOs with 1p/19q co-deletion are prognostically favorable, regardless of therapy, and must be identified as early as possible. Following resection, outcome data on initial therapy with radiation (RT) remain the most mature, although controversies regarding its true toxicities and optimal timing continue. Recently, the landmark RTOG 9402 and EORTC 26951 trials showed that the addition of Procarbazine, CCNU, Vincristine chemotherapy to RT, at anytime during initial therapy, prolongs progression-free survival, but not survival, and not without moderate toxicity. Despite a lack of definitive evidence, this strategy has commonly been extrapolated to Temozolomide. Chemo-sensitivity of AO/mixed-AOs provides the rationale for the chemotherapy-only strategies being explored. In the setting of recurrence/progression (R/P), chemotherapy, small molecule (targeted), biologic, and other strategies have been relatively disappointing, toxic, and cumbersome. Partly secondary to biases regarding the relative toxicities of tumor burden vs. treatment effect, therapy remains highly individualized. Future international research must prospectively evaluate health-related quality of life, toxicity, and molecular genetic markers.

    2009-06-01

    Purpose: Anaplastic thyroid carcinoma (ATC) is one of the most aggressive cancers, and the current protocol of hyperfractionated accelerated radiotherapy was initiated to improve survival while limiting toxicities. Methods and Materials: All patients with ATC from 1991 to 2002 were accrued and received megavoltage radiotherapy from the mastoid processes to the carina up to 60 Gy in twice-daily fractions of 1.8 and 2 Gy, 6 hours apart. Results: Thirty-one patients were accrued with a median age of 69 years, and 55% were women. Debulking was performed in 26%, and total thyroidectomy, in 6%, whereas 68% received radical radiotherapy alone. Local control data were available for 27 patients: 22% had a complete response, 26% had a partial response, 15% showed progressive disease, and 37% showed static disease. Median overall survival for all 31 patients was 70 days (95% confidence interval, 40-99). There was no significant difference in median survival between patients younger (70 days) and older than 70 years (42 days), between men (70 days) and women (49days), and between patients receiving postoperative radiotherapy (77 days) and radical radiotherapy alone (35 days). Grade III or higher skin erythema was seen in 56% patients; desquamation in 21%; dysphagia in 74%; and esophagitis in 79%. Conclusion: The current protocol failed to offer a significant survival benefit, was associated with severe toxicities, and thus was discontinued. There is a suggestion that younger patients with operable disease have longer survival, but this would require a larger study to confirm it.

    A child was diagnosed in 1969 as having acute lymphoblastic leukaemia (ALL) and received chemotherapy. On bone marrow relapse in 1973, he was treated with cranial irradiation (20 Gy) in addition to chemotherapy. He continues in complete remission 19 years after his relapse. At age 25 years, he presented with headaches and left hemiparesis. Computerised tomograph demonstrated a large, enhancing right-sided intracranial tumour. Angiography was performed and showed the right internal carotid artery was occluded. Most of the right hemisphere was supplied from the external carotid via the middle meningeal artery. The left posterior cerebral artery and the left anterior cerebral artery were absent presumably as a result of radiation-induced arteritis. A resection of an anaplastic meningioma arising from the right sphenoidal ridge was achieved. There was a rapid improvement in function and he returned to work. Vasculopathy of the large intracranial arteries has been described after high dose radiation. It may occur as in this case after moderate dose radiation. There is a correlation with meningioma. There is a possibility that large artery vasculopathy will be present in a proportion of patients irradiated for ALL. The long lag time between irradiation and the development of meningioma may mean that, as survivors of childhood ALL enter their third decade since cure, this tumour may be seen increasingly.

    Four uncommon anaplastic mammary carcinomas containing numerous giant cells are described in three dogs and one cat. The giant cells of all cases were studied by means of monoclonal and polyclonal antibodies to detect epithelial (carcinoembryonic antigen and keratin) and mesenchymal (vimentin, lysozyme and S-100 protein) differentiation. Most of them proved to have an epithelial immunophenotype. Ultrastructurally, scattered bundles of tonofilaments but no lysosome-like bodies could be detected. One tumour had an additional, different type of giant cell, which had a benign multinucleated osteoclast-like appearance, gave positive staining for acid phosphatase, had a histiocytic-stromal immunohistochemical pattern, and was, ultrastructurally, multinucleate with irregular folds and no evidence of tonofilaments. In one case some giant cells had an epithelial immunophenotype and others a stromal immunophenotype, even though their histological and ultrastructural features were the same. In the least histologically differentiated tumour the giant cells presented a coexpression of intermediate filaments. This supported the theory that there might be a stem cell origin for most canine mammary tumours.

    Alcohol engages signaling pathways in the brain. Midkine (MDK) is a neurotrophic factor that is over-expressed in the prefrontal cortex of alcoholics. MDK and one of its receptors, anaplastic lymphoma kinase (ALK), also regulate behavioral responses to ethanol in mice. The goal of this study was to determine whether MDK and ALK expression and signaling are activated by ethanol. We found that ethanol treatment of neuroblastoma cells increased MDK and ALK expression. We also assessed activation of ALK by ethanol in cells and found that ALK and ALK-dependent extracellular signal-regulated kinase (ERK) and signal transducer and activator of transcription 3 (STAT3) phosphorylation increased rapidly with ethanol exposure. Similarly, treatment of cells with recombinant MDK protein increased ALK, ERK and STAT3 phosphorylation, suggesting that ethanol may utilize MDK to activate ALK signaling. In support of this, transfection of cells with MDK siRNAs attenuated ALK signaling in response to ethanol. Ethanol also activates ERK signaling in the brain. We found that inhibition of ALK or knockout of MDK attenuated ethanol-induced ERK phosphorylation in mouse amygdala. These results demonstrate that ethanol engages MDK and ALK signaling, which has important consequences for alcohol-induced neurotoxicity and the regulation of behaviors related to alcohol abuse.

    The present study describes the case of a 63-year-old woman presenting with headache, dizziness and vomiting due to a an ovoid mass in the left pre-bulbar cistern, apparently arising from the lower clivus and the foramen magnum. The clinical history revealed the subtotal removal of a right cerebellar low-grade glioma 15 years previously and subsequent conventional 60-Gy radiotherapy. Notably, following gross total resection, histopathological examination showed microscopic features that resulted in a diagnosis of anaplastic ependymoma. The patient underwent surgery to remove the mass and post-operative chemotherapy with temozolomide. A progressive improvement of neurological signs and symptoms was observed during the postoperative course. At the 6-month follow-up, the patient was free from clinical and radiological recurrence. The unusual features of this rare secondary brain tumor were the extrassial location in the posterior fossa, the unusual age-associated location of the histological subtype and the fact that it closely mimicked a skull-base meningioma.

    Anaplastic Kaposi sarcoma (AKS), a rare variant of Kaposi sarcoma, has a poorly recognized histomorphologic spectrum, including a paucivascular phenotype, that mimics a range of undifferentiated malignancies. This study, that highlights the hitherto undocumented phenomenon of S100-protein-positive Langerhans cells (SLCs) as a potential diagnostic pitfall in paucivascular AKS, involved review of nine such AKS that required diagnostic immunohistochemical (IHC) work-up. All biopsies had a predominant or exclusive spindle or epithelioid cell infiltrate. The first three tumors were diagnosed as malignant peripheral nerve sheath tumor (2) and metastatic melanoma (1), based on S100-protein immunopositivity. Biopsy of a co-existent pigmented sole lesion (patient 3) demonstrated nodular KS. Subsequent IHC investigation of these three tumors demonstrated an endothelial phenotype and HHV8 immunopositivity, confirming AKS. CD1a and langerin staining of the S100-protein-positive cells confirmed Langerhans cells as the cause of the diagnostic pitfall. Subsequently, six further paucivascular AKS with intratumoral SLCs were recognized on histomorphological and IHC appraisal. In conclusion, heightened awareness of the histomorphologic spectrum, appropriate IHC investigation, and informed appraisal thereof, are critical to the diagnosis of AKS with an undifferentiated phenotype, and the avoidance of IHC pitfalls, such as those caused by under-recognition and misinterpretation of bystander SLCs in AKS.

    Anaplastic lymphoma kinase (ALK) is a tyrosine kinase receptor involved in both solid and hematological tumors. About 80% of ALK-positive anaplastic large-cell lymphoma (ALCL) cases are characterized by the t(2;5)(p23;q35) translocation, encoding for the aberrant fusion protein nucleophosmin (NPM)-ALK, whereas 5% of non-small-cell lung cancer (NSCLC) patients carry the inv(2)(p21;p23) rearrangement, encoding for the echinoderm microtubule-associated protein-like 4 (EML4)-ALK fusion. The ALK/c-MET/ROS inhibitor crizotinib successfully improved the treatment of ALK-driven diseases. However, several cases of resistance appeared in NSCLC patients, and ALK amino acid substitutions were identified as a leading cause of resistance to crizotinib. Second-generation ALK inhibitors have been developed in order to overcome crizotinib resistance. In this work, we profiled in vitro the activity of crizotinib, AP26113, ASP3026, alectinib, and ceritinib against six mutated forms of ALK associated with clinical resistance to crizotinib (C1156Y, L1196M, L1152R, G1202R, G1269A, and S1206Y) and provide a classification of mutants according to their level of sensitivity/resistance to the drugs. Since the biological activity of ALK mutations extends beyond the specific type of fusion, both NPM-ALK- and EML4-ALK-positive cellular models were used. Our data revealed that most mutants may be targeted by using different inhibitors. One relevant exception is represented by the G1202R substitution, which was highly resistant to all drugs (>10-fold increased IC50 compared to wild type) and may represent the most challenging mutation to overcome. These results provide a prediction of cross-resistance of known crizotinib-resistant mutations against all second-generation tyrosine kinase inhibitors (TKIs) clinically available, and therefore could be a useful tool to help clinicians in the management of crizotinib-resistance cases.

    Sertoli cell tumours of testes are classified into sertoli cell tumour NOS (not otherwise specified), sclerosing variant and large cell calcifying variant. So far, 90 cases of the large cell calcifying variant have been reported in literature. We describe a rare case of inhibin negative locally invasive large cell calcifying sertoli cell tumour of testis. A 62-year-old man presented with complaints of pain and swelling in right scrotum for 8 months. Ultrasound revealed a right testicular mass with internal vascularity and calcification. Gross examination of right inguinal orchiectomy specimen showed firm to hard mass with yellow areas and calcification seen on cut section. Microscopy revealed a tumour in the testis infiltrating the epididymis and rete testis and reaching up to the skin. Tumour cells were arranged in the form of solid nests, tubules and cords with neutrophilic stromal infiltrate and calcification. Tumour cells had abundant clear to eosinophilic cytoplasm, round nucleus with vesicular chromatin and conspicuous nucleoli. On immunohistochemistry, tumour cells were positive for pan cytokeratin, Epithelial Membrane Antigen (EMA), S-100 protein, desmin, vimentin, neuron specific enolase, and chromogranin. However, it was negative for inhibin alpha, OCT4, CD10, CD99, Melan A. Inhibin negative large cell calcifying sertoli cell tumour is a rare entity. PMID:28050378

    Background and aims: Overexpression of transforming growth factor (TGF)-β1 has been implicated in promoting cell survival, migration and invasion in many cancers, including anaplastic thyroid cancer (ATC). In the present study, we studied the effect of suppressing TGF-β1 by RNA silencing on the survival, invasion and metastasis of ATC cells. Methods: Small interfering RNA (siRNA) constructs targeting TGF-β1 were validated and used to develop clonal derivatives of the ATC cell line, 8505C. The cells were used in several in vitro assays, including migration, invasion, survival rate, colony formation and apoptosis. A wound healing assay was used to determine the migration of cells in culture and a Boyden chamber transwell assay was used for invasion. Further, clones were used in an in vivo mouse model to study the kinetics of tumor growth and metastatic growth in lungs. Results: Targeting TGF-β1 expression in 8505C cells caused a 70% decrease in migration and a 78% decrease in invasion, as well as a 68% decrease in proliferation and a 19% increase in apoptosis in vitro. The growth of primary tumors in vivo was also inhibited when compared with parental 8505C cells; however, the number of mice bearing lung metastases was not significantly decreased. Conclusions: Targeting TGF-β1 may be effective in inhibiting primary tumor formation, but not metastasis, by ATC cells. TGF-β1 inhibition in combination with other tumor-targeted therapies may be more effective in inhibiting ATC. PMID:28386367

    Anaplastic pancreatic carcinoma (ANPC) accounts for ~5% of all pancreatic ductal adenocarcinoma cases. Due to its rarity, its clinical features and surgical outcomes remain to be clearly understood. A 74-year-old woman was admitted to Onomichi General Hospital (Onomichi, Japan) in April 2015 without any significant past medical history. Contrast-enhanced computed tomography (CT) revealed a 9.5×8.0 cm tumor in the body and tail of the pancreas. The patient developed acute abdominal pain 3 weeks later and the CT revealed massive abdominal bleeding caused by tumor rupture. The tumor increased in size and reached 12.0×10.0 cm in maximal diameter. The tumor doubling time was estimated to be 13 days. 18F-fluorodeoxyglucose (FDG) positron emission tomography/CT confirmed the absence of distant metastasis since FDG accumulation was detected only in the tumor lesion. Emergency distal pancreatectomy and splenectomy were performed. Histologically, the tumor was classified as a spindle cell ANPC with rhabdoid features. The patient succumbed to mortality 8 months following the surgery while undergoing systemic adjuvant chemotherapy for multiple liver metastases. ANPC is difficult to detect in the early stages due to its progressive nature and atypical radiological findings. Long-term survival can be achieved only by curative resection; therefore, surgical resection must be performed whenever possible, even if the chance of long-term survival following surgery is considered dismal. As the present case suggested, spindle cell ANPC with rhabdoid features is highly aggressive and curative-intent resection must not be delayed. PMID:27446572

    Heterozygous Neurofibromatosis 1 (NF1) loss of function mutations occur in approximately 90% of patients with neurofibromatosis. A major, disabling phenotypic consequence of reduced NF1 function is cognitive impairment; a possibly related behavioral phenotype is impaired sleep. Recent results in Drosophila have demonstrated a genetic interaction between Anaplastic Lymphoma Kinase (Alk) and NF1 for both associative learning and sleep. Inhibition of Alk improves associative learning and sleep in heterozygous NF1 mutant flies. The results in Drosophila provide a strong motivation to investigate NF1/Alk genetic interactions in mice. In Drosophila, activation of Alk by its ligand, Jelly belly (Jeb), is the physiologically relevant target of negative regulation by NF1. Therefore, we tested whether genetic inhibition of Alk in heterozygous NF1 mutant mice attenuates or rescues cognitive impairments in mice. Our results are consistent with the hypothesis that NF1 functions in mice biochemically to inhibit signaling from Alk through Ras. The cognitive phenotypes observed in heterozygous NF1 mutant mice are rescued or ameliorated by genetic inhibition of Alk activity. In two tests of hippocampus-dependent learning, the Morris water maze and extinction of contextual fear, mutation of one or both alleles of Alk was sufficient to improve performance to wild type or near wild type levels in NF1-/+ mice. In addition, in NF1 mice genetic inhibition of Alk improves circadian activity levels. These data are intriguing in light of the circadian alterations seen in NF1 patients and indicate that inhibition of Alk activity may cognitively benefit patients with Neurofibromatosis 1.

    Anaplastic thyroid carcinoma (ATC) is one of the most malignant tumors in humans, and currently there is no effective treatment. In the present study we investigated the effect of an endogenous estrogen metabolite, 2-methoxyestradiol (2-ME), on the growth of human ATC cells. 2-ME treatment had a strong growth inhibitory effect on five human ATC cell lines (HTh7, HTh 74, HTh83, C643, and SW1736), but showed no effect on one cell line (KAT-4). Cell cycle analysis of the growth-inhibited cells showed that 2-ME induced a G2/M-arrest, followed by an increased fraction of cells in sub-G1. Analysis of internucleosomal DNA laddering as well as DNA fragmentation in a terminal deoxynucleotide transferase-mediated dUTP nick-end labeling (TUNEL) assay demonstrated a high number of cells undergoing apoptosis after 2-ME treatment. An increased activation of caspase-3 and caspase-8 by 2-ME was observed, and inhibition of caspase-3 decreased the apoptotic effect. Addition of 2-ME increased activity of p38 mitogen-activated protein kinase (MAPK) in the sensitive HTh7 as well as the refractory KAT-4 cells, however, activation of stress-activated protein kinase/c-jun aminoterminal kinase (SAPK/JNK) was seen only in the HTh7 cells. Inhibitors of p38 MAPK and SAPK/JNK significantly attenuated the 2-ME effect. Taken together, our data demonstrate an antiproliferative and apoptotic effect of 2-ME on ATC cells involving activation of MAPKs.

    Anaplastic thyroid cancer (ATC) is the most aggressive solid tumour known and is a rare but highly lethal form of thyroid cancer that requires a multidisciplinary team approach. No Spanish consensus exists for management of patients with ATC. The Thyroid Cancer Group of the Spanish Society of Endocrinology and Nutrition and the GETHI (Grupo Español de Enfermedades Huérfanas e Infrecuentes) of the Spanish Society of Oncology, in agreement with the Boards of these Societies, commissioned an independent task force to develop a wide consensus on ATC. The relevant literature was reviewed, including serial PubMed searches supplemented with additional articles. The consensus includes the characteristics, diagnosis, initial evaluation, establishment of treatment goals, approaches to locoregional disease (surgery, radiotherapy, systemic therapy, supportive care during active treatment), approaches to advanced/metastatic disease, palliative care options, monitoring, and long-term follow-up of ATC. For operable disease, a combination of radical surgery with adjuvant radiotherapy or chemotherapy, using agents such as doxorubicin, cisplatin and paclitaxel, is the best treatment strategy. Cytotoxic drugs are poorly effective for advanced/metastatic ATC. On the other hand, targeted agents may represent a viable therapeutic option. Patients with stage IVA/IVB resectable disease have the best prognosis, particularly if a multimodal approach is used, and some stage IVB unresectable patients may respond to aggressive therapy. Patients with stage IVC disease should be considered for clinical trials or for hospice/palliative care depending on their preference. This is the first Spanish consensus for ATC, and provides recommendations for management of this extremely aggressive malignancy. Novel systemic therapies are being tested, and more effective combinations are needed to improve patient outcomes. Although more aggressive radiotherapy has reduced locoregional recurrence, mean

    Anaplastic thyroid carcinoma (ATC) is one of the most aggressive human malignancies. The aggressive behavior of ATC and its resistance to traditional treatment limit the efficacy of radiotherapy, chemotherapy, and surgery. The purpose of this study is aimed at enhancing the therapeutic efficacy of radiotherapy (RT) combined with photothermal therapy (PTT) in murine orthotopic model of ATC, based on our developed single radioactive copper sulfide (CuS) nanoparticle platform. We prepare a new dual-modality therapy for ATC consisting of a single-compartment nanoplatform, polyethylene glycol-coated [64Cu]CuS NPs, in which the radiotherapeutic property of 64Cu is combined with the plasmonic properties of CuS NPs. Mice with Hth83 ATC were treated with PEG[64Cu]CuS NPs and/or near infrared laser. Antitumor effects were assessed by tumor growth and animal survival. We found that in mice bearing orthotopic human Hth83 ATC tumors, micro-PET/CT imaging and biodistribution studies showed that about 50% of the injected dose of PEG-[64Cu]CuS NPs was retained in tumor 48 h after intratumoral injection. Human absorbed doses were calculated from biodistribution data. In antitumor experiments, tumor growth was delayed by PEG-[64Cu]CuS NP-mediated RT, PTT, and combined RT/PTT, with combined RT/PTT being most effective. In addition, combined RT/PTT significantly prolonged the survival of Hth83 tumor-bearing mice compared to no treatment, laser treatment alone, or NP treatment alone without producing acute toxic effects. These findings indicate that this single-compartment multifunctional NPs platform merits further development as a novel therapeutic agent for ATC. PMID:25913249

    Treatment for newly diagnosed anaplastic oligodendroglial tumors is controversial. Radiotherapy (RT) alone and in combination with chemotherapy (CT) are the most well studied strategies. However, CT alone is often advocated, especially in cases with 1p19q codeletion. We retrospectively identified 1013 adults diagnosed from 1981-2007 treated initially with RT alone (n = 200), CT + RT (n = 528), CT alone (n = 201), or other strategies (n = 84). Median overall survival (OS) was 6.3 years and time to progression (TTP) was 3.1 years. 1p19q codeletion correlated with longer OS and TTP than no 1p or 19q deletion. In codeleted cases, median TTP was longer following CT + RT (7.2 y) than following CT (3.9 y, P = .003) or RT (2.5 y, P < .001) alone but without improved OS; median TTP was longer following treatment with PCV alone than temozolomide alone (7.6 vs. 3.3 y, P = .019). In cases with no deletion, median TTP was longer following CT + RT (3.1 y) than CT (0.9 y, P = .0124) or RT (1.1 y, P < .0001) alone; OS also favored CT + RT (median 5.0 y) over CT (2.2 y, P = .02) or RT (1.9 y, P < .0001) alone. In codeleted cases, CT alone did not appear to shorten OS in comparison with CT + RT, and PCV appeared to offer longer disease control than temozolomide but without a clear survival advantage. Combined CT + RT led to longer disease control and survival than did CT or RT alone in cases with no 1p19q deletion. Ongoing trials will address these issues prospectively.

    Background Anaplastic lymphoma kinase (ALK) rearrangements define a subgroup of lung cancer which is eligible to targeted kinase inhibition. The aim of this study is to observe the incidence rate of ALK fusion in a large cohort of Chinese digestive tract cancer patients. Patients and Methods Tissue microarray (TMA) was constructed from 808 digestive tract cancer cases, including 169 esophageal squamous cell carcinoma, 182 gastric cancer and 457 colorectal cancer (CRC) cases. We tested all cases for ALK expression via a fully automated immunohistochemistry (IHC) assay. The IHC-positive cases were subjected to fluorescence in situ hybridization (FISH), real-time polymerase chain reaction (qRT-PCR), target gene enrichment and sequencing for confirmation of ALK gene rearrangement and discovery of novel fusion partner. Results Among the tested cases, 2 (0.44%) CRC cases showed positive both by IHC and FISH. By qRT-PCR, EML4–ALK fusion was found in one IHC-positive CRC case. In another IHC-positive CRC case, target gene enrichment and sequencing revealed ALK was fused to a novel partner, spectrin beta non-erythrocytic 1 (SPTBN1). One gastric cancer case showed partially positive IHC result, but no fusion was found by FISH and gene sequencing. Conclusions The incidence rate of ALK gene fusion in Chinese CRC patients was 0.44%,but not detectable in gastric and esophageal cancers. The novel SPTBN1 -ALK fusion, together with other ALK fusion genes, may become a potential target for anti-ALK therapy. PMID:26678488

    Aurora kinases are serine/threonine kinases that play an essential role in cell division. Their aberrant expression and/or function induce severe mitotic abnormalities, resulting in either cell death or aneuploidy. Overexpression of Aurora kinases is often found in several malignancies, among which is anaplastic thyroid carcinoma (ATC). We have previously demonstrated the in vitro efficacy of Aurora kinase inhibitors in restraining cell growth and survival of different ATC cell lines. In this study, we sought to establish which Aurora might represent the preferential drug target for ATC. To this end, the effects of two selective inhibitors of Aurora-A (MLN8237) and Aurora-B (AZD1152) on four human ATC cell lines (CAL-62, BHT-101, 8305C, and 8505C) were analysed. Both inhibitors reduced cell proliferation in a time- and dose-dependent manner, with IC50 ranges of 44.3-134.2 nM for MLN8237 and of 9.2-461.3 nM for AZD1152. Immunofluorescence experiments and time-lapse videomicroscopy yielded evidence that each inhibitor induced distinct mitotic phenotypes, but both of them prevented the completion of cytokinesis. As a result, poliploidy increased in all AZD1152-treated cells, and in two out of four cell lines treated with MLN8237. Apoptosis was induced in all the cells by MLN8237, and in BHT-101, 8305C, and 8505C by AZD1152, while CAL-62 exposed to AZD1152 died through necrosis after multiple rounds of endoreplication. Both inhibitors were capable of blocking anchorage-independent cell growth. In conclusion, we demonstrated that either Aurora-A or Aurora-B might represent therapeutic targets for the ATC treatment, but inhibition of Aurora-A appears more effective for suppressing ATC cell proliferation and for inducing the apoptotic pathway.

    Astrocytoma is the most common childhood brain tumor. Anaplastic astrocytoma (AA) are high grade gliomas (HGG), found very rarely in pediatric patients. AA mainly results from a dedifferentiation of a low grade astrocytoma. Clinical features of supra-tentorial tumors vary according to their anatomic location, biologic aggressiveness and age of the patient. They can be either completely asymptomatic or present with signs of raised intracranial pressure, seizures (about 40% of cases), behavior changes, speech disorders, declining school performance, or hemiparesis. There have been published adult cases of brain tumor misdiagnosed as viral encephalitis. Due to variety of clinical presentations, diagnosis of AA can be challenging. Here we report a case of a 13 year old girl who presented with clinical features suggestive of viral encephalitis, such as fever, headache, dizziness, and first seizure with postictal sleep and prolonged drowsiness. However, her brain MRI findings were consistent with long standing mass effect from the underlying intracranial contents and that coupled with her history of unusual taste led to further investigations and the diagnosis of the AA. In retrospect, this presentation could have been a temporal epileptic aura. High grade astrocytomas are particularly difficult to treat with a two-year survival rates range from 10% to 30%. The treatment is multimodal with gross total surgical resection of the tumor, followed by radiotherapy with or without nitrosourea-containing chemotherapy regimen. Recent promising results seen with the use of temozolamide in adults has not been yet demonstrated in the pediatric patients. The extent of tumor resection remains the most significant indicator of survival and early recognition of this tumor is essential. This case report emphasizes the fact that mass lesions in the temporal lobe, including high-grade astrocytoma, should be considered in the differential diagnosis of suspected herpes simplex encephalitis

    Positron emission tomography/computed tomography (PET/CT) with 18F-fluorodeoxyglucose (FDG) is used in staging, restaging, and evaluation of therapy response in many cancers as well as differentiated thyroid carcinomas especially in non-iodine avid variants. Its potential in less frequent thyroid tumors like medullary, anaplastic thyroid cancers, thyroid lymphoma and metastatic tumors of the thyroid however, is not well established yet. The aim of this review is to provide an overview on the recent applications and indications of 18F-FDG PET/CT in these tumors and to focus on the controversies in the clinical setting. PMID:28291004

    Radiotherapy forms part of most therapeutic, preventive, and conditioning regimens in pediatric oncology. Numerous late secondary effects of cranial radiation are well known. However, radiation-induced cavernous angiomas (RICA) have been reported only sporadically and even fewer cases of earlier presentation of RICA have been reported. In this brief report, we describe a RICA that appeared in a boy treated for a CNS tumor (an infratentorial anaplastic ependymoma) after a short latency period between the end of radiotherapy and the development of the RICA. We comment on the different variables proposed to explain the formation of these lesions, as well as on their imaging features, treatment, prognosis, and follow-up.

    A 3-year-old boy with sickle cell anemia (SCA) presented with progressive daily emesis and was found to have an anaplastic ependymoma. Radiation therapy and chemotherapy are usually employed after subtotal resections of anaplastic ependymomas, although the benefits from chemotherapy are unclear. To mitigate the risks of adjuvant treatment in this patient at risk for SCA-associated vasculopathy, renal impairment, and other end-organ damage, proton beam irradiation without chemotherapy was chosen. Scheduled packed red blood cell transfusions were instituted to maintain sickle hemoglobin levels less than 30%. This case highlights treatment complexities for malignant brain tumors in patients predisposed to treatment-related adverse effects.

    A 74-year-old male presented with a large polinodular mass in the neck. Fine needle aspiration cytology (FNAC) showed an undifferentiated large cell carcinoma. Computed tomography (CT) showed a large parotid mass with multiple satelite nodules. The remaining radiological studies were normal. Radical parotidectomy was performed. The tumor was a large cell carcinoma with neuroendocrine features and positive immunostain for neuroendocrine markers. The patient received postoperative radiotherapy and was free of tumor eight months later. Only four cases of large cell neuroendocrine carcinoma (LCNEC) of the salivary gland have been communicated. All of them have involved the parotid gland. This tumor presents in elderly patients as a large infiltrating parotid mass. Fine needle aspiration cytology serves to recognize the carcinoma, but it fails in recognizing the neuroendocrine features of the tumor. The histopathological features of this tumor are the same as in other organs. Chromogranin and synaptophysin are useful immunohistochemical markers. A primary location of the tumor in another organ, specially the lung, should be ruled out. Surgery is the main treatment modality and can be complemented with postoperative radiotherapy. The prognosis seems to be poor. More studies are needed to better define the therapeutical alternatives and prognostic factors of these rare tumors.

    Background Anaplastic thyroid cancer (ATC) is one of the most aggressive human malignancies and appears to arise mainly from transformation of pre-existing differentiated thyroid cancer (DTC). However, the carcinogenic mechanism of anaplastic transformation remains unclear. Previously, we investigated specific genes related to ATC based on gene expression profiling using cDNA microarray analysis. One of these genes, transcription elongation factor A (SII)-like 4 (TCEAL4), encodes a member of the transcription elongation factor A (SII)-like gene family. The detailed function of TCEAL4 has not been described nor has any association between this gene and human cancers been reported previously. Methods To investigate the role of TCEAL4 in ATC carcinogenesis, we examined expression levels of TCEAL4 in ACLs as well as in other types of thyroid cancers and normal human tissue. Results Expression of TCEAL4 was down-regulated in all 11 ACLs as compared to either normal thyroid tissues or papillary and follicular thyroid cancerous tissues. TCEAL4 was expressed ubiquitously in all normal human tissues tested. Conclusion To our knowledge, this is the first report of altered TCEAL4 expression in human cancers. We suggest that loss of TCEAL4 expression might be associated with development of ATC from DTC. Further functional studies are required. PMID:17076909

    We report on the case of a 67-year-old man with granulocyte colony-stimulating factor (G-CSF) producing anaplastic carcinoma of the pancreas. Preoperative routine tests revealed an elevated white blood cell (WBC) count of 25.2 G/l, consisting almost exclusively of neutrophilic granulocytes (23.31 G/l) with a predominance of segmented neutrophils (78% of all neutrophilic granulocytes), and elevated levels of C-reactive protein at 87 mg/l. Upon surgery, local tumour infiltration was more extensive than expected from preoperative imaging. However, no peritoneal dissemination was found and curative resection was attempted. Only seven days after the operation, signs of relapse were seen upon computed tomograpy. Histology revealed an undifferentiated anaplastic carcinoma, on the basis of a poorly differentiated ductal adenocarcinoma. Immunohistochemistry demonstrated G-CSF and G-CSF-Receptor expression in some CD68-positive syncytial macrophages. Granulocyte colony-stimulating factor (G-CSF) in serum was elevated at 5.6 pg/ml, which further raised to 43 pg/ml one week after FOLFIRINOX chemotherapy (oxaliplatin, irinotecan, 5-fluorouracil), while WBC decreased from 103.3 G/l to 59.3 G/l. Granulocyte macrophage-colony stimulating factor (GM-CSF) in serum was normal (<0.5 pg/ml). The patient died on postoperative day 34.

    Personalized medicine is a set of diagnostic, prognostic and therapeutic approaches in which medical interventions are carried out based on individual patient characteristics. As life expectancy increases in developed and developing countries, the incidence of diseases such as cancer goes up among people in the community. Cancer is a disease that the response to treatment varies from one person to another and also it is costly for individuals, families, and society. Among thyroid cancers, anaplastic thyroid carcinoma (ATC) is the most aggressive, lethal and unresponsive form of the disease. Unfortunately, current drugs are not targetable, and therefore they have restricted role in ATC treatment. Consequently, mortality of this cancer, despite advances in the field of diagnosis and treatment, is one of the most important challenges in medicine. Cellular, molecular and genetic evidences play an important role in finding more effective diagnostic and therapeutic approaches. Review of these evidences confirms the application of personalized medicine in cancer treatment including ATC. A growing body of evidence has elucidated that cellular and molecular mechanisms of cancer would pave the way for defining new biomarkers for targeted therapy, taking into account individual differences. It should be noted that this approach requires further progress in the fields of basic sciences, pharmacogenetics and drug design. An overview of the most important aspects in individualized anaplastic thyroid cancer treatment will be discussed in this review.

    Mutations in isocitrate dehydrogenase 1 (IDH1) have been found in the vast majority of low grade and progressive infiltrating gliomas and are characterized by the production of 2-hydroxyglutarate from α-ketoglutarate. Recent investigations of malignant gliomas have identified additional genetic and chromosomal abnormalities which cluster with IDH1 mutations into two distinct subgroups. The astrocytic subgroup was found to have frequent mutations in ATRX, TP53 and displays alternative lengthening of telomeres. The second subgroup with oligodendrocytic morphology has frequent mutations in CIC or FUBP1, and is linked to co-deletion of the 1p/19q arms. These mutations reflect the development of two distinct molecular pathways representing the majority of IDH1 mutant gliomas. Unfortunately, due to the scarcity of endogenously derived IDH1 mutant models, there is a lack of accurate models to study mechanism and develop new therapy. Here we report the generation of an endogenous IDH1 anaplastic astrocytoma in vivo model with concurrent mutations in TP53, CDKN2A and ATRX. The model has a similar phenotype and histopathology as the original patient tumor, expresses the IDH1 (R132H) mutant protein and exhibits an alternative lengthening of telomeres phenotype. The JHH-273 model is characteristic of anaplastic astrocytoma and represents a valuable tool for investigating the pathogenesis of this distinct molecular subset of gliomas and for preclinical testing of compounds targeting IDH1 mutations or alternative lengthening of telomeres.

    To determine the impact of insurance status and income for anaplastic astrocytoma (AA). Data were extracted from the National Cancer Data Base. Chi square test, Kaplan-Meier method, and Cox regression models were employed in SPSS 22.0 (Armonk, NY: IBM Corp.) for data analyses. 4325 patients with AA diagnosed from 2004 to 2013 were identified. 2781 (64.3%) had private insurance, 925 (21.4%) Medicare, 396 (9.2%) Medicaid, and 223 (5.2%) were uninsured. Those uninsured were more likely to be Black or Hispanic versus White or Asian (p < 0.001), have lower median income (p < 0.001), less educated (p < 0.001), and not receive adjuvant chemoradiation (p < 0.001). 1651 (38.2%) had income ≥$63,000, 1204 (27.8%) $48,000-$62,999, 889 (20.5%) $38,000-$47,999, and 581 (13.4%) had income <$38,000. Those with lower income were more likely to be Black or Hispanic versus White or Asian (p < 0.001), uninsured (p < 0.001), reside in a rural area (p < 0.001), less educated (p < 0.001), and not receive adjuvant chemoradiation (p < 0.001). Those with private insurance had significantly higher overall survival (OS) than those uninsured, on Medicaid, or on Medicare (p < 0.001). Those with income ≥$63,000 had significantly higher OS than those with lower income (p < 0.001). On multivariate analysis, age, insurance status, income, and adjuvant therapy were independent prognostic factors for OS. Being uninsured and having income <$38,000 were independent prognostic factors for worse OS in AA. Further investigations are warranted to help determine ways to ensure adequate medical care for those who may be socially disadvantaged so that outcome can be maximized for all patients regardless of socioeconomic status.

    Adhesion of tumor cells to the extracellular matrix (ECM) is a crucial step for the development of metastatic disease and is mediated by specific integrin receptor molecules (IRM). The pattern of metastatic spread differs substantially among the various histotypes of thyroid cancer (TC). However, IRM have only occasionally been characterized in TC until now. IRM expression was investigated in 10 differentiated (FTC133, 236, 238, HTC, HTC TSHr, XTC, PTC4.0/4.2, TPC1, Kat5) and two anaplastic TC cell lines (ATC, C643, Hth74), primary cultures of normal thyroid tissue (Thy1,3), and thyroid cancer specimens (TCS). Expression of 16 IRM (beta1-4, beta7, alpha1-6, alphaV, alphaIIb, alphaL, alphaM, alphaX) and of four IRM heterodimers (alpha2beta1, alpha5beta1, alphaVbeta3, alphaVbeta5), was analyzed by fluorescent-activated cell sorter (FACS) and immunohistochemical staining. Thyroid tumor cell adhesion to ECM proteins and their IRM expression in response to thyrotropin (TSH) was assessed. Follicular TC cell lines presented high levels of integrins alpha2, alpha3, alpha5, beta1, beta3 and low levels of alpha1, whereas papillary lines expressed a heterogenous pattern of IRM, dominated by alpha5 and beta1. ATC mainly displayed integrins alpha2, alpha3, alpha5, alpha6, beta1 and low levels of alpha1, alpha4 and alphaV. Integrin heterodimers correlated with monomer expression. Evaluation of TCS largely confirmed these results with few exceptions, namely alpha4, alpha6, and beta3. The ability of TC cell lines to adhere to purified ECM proteins correlated with IRM expression. TSH induced TC cell adhesion in a dose-dependent fashion, despite an unchanged array of IRM expression or level of a particular IRM. Thyroid carcinoma cell lines of different histogenetic background display profoundly different patterns of IRM expression that appear to correlate with tumor aggressiveness. In vitro adhesion to ECM proteins and IRM expression concur. Finally, TSH-stimulated adhesion of

Poorly differentiated thyroid cancer (PDTC) and anaplastic thyroid cancer (ATC) are rare and frequently lethal tumors that so far have not been subjected to comprehensive genetic characterization. METHODS. We performed next-generation sequencing of 341 cancer genes from 117 patient-derived PDTCs and ATCs and analyzed the transcriptome of a representative subset of 37 tumors. Results were analyzed in the context of The Cancer Genome Atlas study (TCGA study) of papillary thyroid cancers (PTC). RESULTS. Compared to PDTCs, ATCs had a greater mutation burden, including a higher frequency of mutations in TP53, TERT promoter, PI3K/AKT/mTOR pathway effectors, SWI/SNF subunits, and histone methyltransferases. BRAF and RAS were the predominant drivers and dictated distinct tropism for nodal versus distant metastases in PDTC. RAS and BRAF sharply distinguished between PDTCs defined by the Turin (PDTC-Turin) versus MSKCC (PDTC-MSK) criteria, respectively. Mutations of EIF1AX, a component of the translational preinitiation complex, were markedly enriched in PDTCs and ATCs and had a striking pattern of co-occurrence with RAS mutations. While TERT promoter mutations were rare and subclonal in PTCs, they were clonal and highly prevalent in advanced cancers. Application of the TCGA-derived BRAF-RAS score (a measure of MAPK transcriptional output) revealed a preserved relationship with BRAF/RAS mutation in PDTCs, whereas ATCs were BRAF-like irrespective of driver mutation. CONCLUSIONS. These data support a model of tumorigenesis whereby PDTCs and ATCs arise from well-differentiated tumors through the accumulation of key additional genetic abnormalities, many of which have prognostic and possible therapeutic relevance. The widespread genomic disruptions in ATC compared with PDTC underscore their greater virulence and higher mortality. FUNDING.

    We report a WHO grade III ependymoma of the supratentorial interhemispheric fissure and grew to form a large mass with anaplastic transformation without local recurrence 17 years after the total removal of a fourth ventricular WHO grade II ependymoma. We emphasize the necessity of long-term follow-up, even in benign ependymomas.

    This study aimed at challenging pulmonary large cell carcinoma (LLC) as tumor entity and defining different subgroups according to immunohistochemical and molecular features. Expression of markers specific for glandular (TTF-1, napsin A, cytokeratin 7), squamous cell (p40, p63, cytokeratins 5/6, desmocollin-3), and neuroendocrine (chromogranin, synaptophysin, CD56) differentiation was studied in 121 LCC across their entire histological spectrum also using direct sequencing for epidermal growth factor receptor (EGFR) and v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations and FISH analysis for ALK gene translocation. Survival was not investigated. All 47 large cell neuroendocrine carcinomas demonstrated a true neuroendocrine cell lineage, whereas all 24 basaloid and both 2 lymphoepithelioma-like carcinomas showed squamous cell markers. Eighteen out of 22 clear cell carcinomas had glandular differentiation, with KRAS mutations being present in 39 % of cases, whereas squamous cell differentiation was present in four cases. Eighteen out of 20 large cell carcinomas, not otherwise specified, had glandular differentiation upon immunohistochemistry, with an exon 21 L858R EGFR mutation in one (5 %) tumor, an exon 2 KRAS mutation in eight (40 %) tumors, and an ALK translocation in one (5 %) tumor, whereas two tumors positive for CK7 and CK5/6 and negative for all other markers were considered adenocarcinoma. All six LCC of rhabdoid type expressed TTF-1 and/or CK7, three of which also harbored KRAS mutations. When positive and negative immunohistochemical staining for these markers was combined, three subsets of LCC emerged exhibiting glandular, squamous, and neuroendocrine differentiation. Molecular alterations were restricted to tumors classified as adenocarcinoma. Stratifying LCC into specific categories using immunohistochemistry and molecular analysis may significantly impact on the choice of therapy.

    Abstract Rationale: The case reported the rapid remission of disease recurrence achieved adding foscarnet, a DNA polymerase inhibitor that interacts with fibroblast growth factor 2, to low molecular weight heparin and sunitinib for the first time in a patient with an anaplastic thyroid cancer (ATC). Patient concerns: A 65-year-old woman with a multinodular goiter referred for a rapid enlargement of a nodule. Histological examination revealed an ATC with a little area of papillary thyroid cancer (PTC). The patient was resistant to selective single-target treatment. DIagnoses: Immunophenotyping and gene analyses found a significant increase in FGF2 and FGFR1 expression in the primary ATC area (FGF2 = 38.2 ± 6.2% in ATC vs 34.6 ± 6.0% in the differentiated area of PTC, P < 0.05; FGFR1: 41.7 ± 6.0% in ATC vs 34.4 ± 4.2% in PTC, P < 0.001) and in metastatic neck lymph nodes (P < 0.001 vs normal control tissues). Unlike conventional imaging, 18F-FDG PET/CT with PERCIST 1.0 criteria promptly and quantitatively detected disease recurrence and remission before and after multitarget therapy, combining anatomic, metabolic, and functional data. Interventions: Foscarnet was administered given the positivity for FGF2, FGFR1 and FGFR4 in ATC. Low molecular wight heparin and Sunitinib were coadministere to limiti metastatic progression and on neck tumor masse, respectively. Outcomes: The rationale for the clinical response to this innovative multitarget association with foscarnet is based on the histological and genetic finding that fibroblast growth factors and their receptor super-family are up-regulated in the primary anaplastic thyroid tumor and in the metastatic lymph node of our patient. Lessons: We propose that fibroblast growth factors and their receptor super-family play a key role as potential therapeutic targets in anaplastic thyroid cancer and the positive relevance of this suggestion for patient care, especially for an

    Suppression subtractive hybridization (SSH) was used to isolate genes that were differentially expressed in anaplastic lymphoma kinase (ALK)-positive and ALK-negative anaplastic large cell lymphoma. In addition, this approach was applied to Hodgkin's disease cases with different clinical outcomes. SSH combines a normalization step that equalizes the abundance of cDNAs within the sequences to be tested and a subtraction step that excludes the common sequences between the target and the control. In a model system, the SSH technique enriches for rare sequences up to 5,000-fold in one round. We have isolated several genes whose expression varied significantly with regard to the tumour subtypes. There were different genes with known or unknown functions. We aim to compare the results of the SSH approach with those obtained with high density filters. In a near future, we would like to design DNA chips specific of each pathology that could be used for clinical purposes (evaluation of prognosis and therapeutic response).

    Anaplastic large cell lymphoma represents a subset of neoplasms caused by translocations that juxtapose the anaplastic lymphoma kinase (ALK) to dimerization partners. The constitutive activation of ALK fusion proteins leads to cellular transformation through a complex signaling network. To elucidate the ALK pathways sustaining lymphomagenesis and tumor maintenance, we analyzed the tyrosine-kinase protein profiles of ALK-positive cell lines using 2 complementary proteomic-based approaches, taking advantage of a specific ALK RNA interference (RNAi) or cell-permeable inhibitors. A well-defined set of ALK-associated tyrosine phosphopeptides, including metabolic enzymes, kinases, ribosomal and cytoskeletal proteins, was identified. Validation studies confirmed that vasodilator-stimulated phosphoprotein and 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/inosine monophosphate cyclohydrolase (ATIC) associated with nucleophosmin (NPM)-ALK, and their phosphorylation required ALK activity. ATIC phosphorylation was documented in cell lines and primary tumors carrying ALK proteins and other tyrosine kinases, including TPR-Met and wild type c-Met. Functional analyses revealed that ALK-mediated ATIC phosphorylation enhanced its enzymatic activity, dampening the methotrexate-mediated transformylase activity inhibition. These findings demonstrate that proteomic approaches in well-controlled experimental settings allow the definition of informative proteomic profiles and the discovery of novel ALK downstream players that contribute to the maintenance of the neoplastic phenotype. Prediction of tumor responses to methotrexate may justify specific molecular-based chemotherapy.

    The aim of the present study was to analyze and summarize the clinicopathological characteristics of large-cell lung carcinoma (LCLC) of the lung, in order to improve the definite diagnosis rate of LCLC. Clinicopathological data of 174 patients with LCLC, confirmed pathologically, were retrospectively reviewed. The 174 cases of LCLC accounted for 5.7% of the total lung cancer cases during the corresponding time period at the Affiliated Cancer Hospital of Tianjin Medical University (Tianjin, China), among which there were 131 males and 43 females with an average age of 61.4 years. The postoperative pathological diagnosis of the 174 cases showed 80 cases of classic LCLC, 64 cases of large cell neuroendocrine carcinoma (LCNEC), six cases of combined LCNEC, 19 cases of basaloid carcinoma, three cases of clear cell carcinoma and two cases of lymphoepithelioma-like carcinoma. Of the total 174 LCLC cases, 96 patients exhibited lymph node metastasis. LCLC is a highly aggressive malignancy with a high tendency of invasion and metastasis, although the incidence rate is low. A definite diagnosis of LCLC primarily relies on the pathological diagnosis. Each subtype of LCLC has its own pathomorphological and immunohistochemical characteristics. PMID:25452802

    Peripheral T cell lymphomas (PTCL) are rare in children and adolescents, and data about outcome and treatment results are scarce. The present study is a joint, international, retrospective analysis of 143 reported cases of non-anaplastic PTCL in patients <19 years of age, with a focus on treatment and outcome features. One hundred forty-three patients, between 0.3 and 18.7 years old, diagnosed between 2000 and 2015 were included in the study. PTCL not otherwise specified was the largest subgroup, followed by extranodal NK/T cell lymphoma, hepatosplenic T cell lymphoma (HS TCL), and subcutaneous panniculitis-like T cell lymphoma (SP TCL). Probability of overall survival (pOS) at 5 years for the whole group was 0.56 ± 0.05, and probability of event-free survival was (pEFS) 0.45 ± 0.05. Patients with SP TCL had a good outcome with 5-year pOS of 0.78 ± 0.1 while patients with HS TCL were reported with 5-year pOS of only 0.13 ± 0.12. Twenty-five percent of the patients were reported to have a pre-existing condition, and this group had a dismal outcome with 5-year pOS of 0.29 ± 0.09. The distribution of non-anaplastic PTCL subtypes in pediatric and adolescent patients differs from what is reported in adult patients. Overall outcome depends on the subtype with some doing better than others. Pre-existing conditions are frequent and associated with poor outcomes. There is a clear need for subtype-based treatment recommendations for children and adolescents with PTCL.

    Serial computed tomography (CT) plays an integral part in monitoring effects of therapy for primary anaplastic brain tumors. Despite advances in CT technology, clinicians often cannot obtain accurate quantitative volume information to complement the qualitative assessment of tumor change. This paper presents a microcomputer-based method that provides both quantitative volume measurements and 3-D reconstructions of primary anaplastic brain tumors based on their hard copy CT or magnetic resonance imaging studies. The findings of this study demonstrate that planimetry is feasible for routine clinical use and is superior in accuracy to the spherical geometric model, which is shown to significantly overestimate tumor volume. The findings of 62 quantitative tumor studies (17 patients) showed a direct relationship between the total tumor volume and the volume of the hypodense intratumor core. There was no evidence of a relationship between the total tumor volume and the amount of peritumor low density (edema).

    Pleomorphic xanthoastrocytoma (PXA) is a rare localized glioma characterized by frequent BRAF V600E mutation and CDKN2A/B deletion. We explored the association of copy-number variants (CNVs) with BRAF mutations, tumor grade, and patient survival in a cohort of 41 PXA patients using OncoScan chromosomal microarray. Primary resection specimens were available in 38 cases, including 24 PXA and 14 anaplastic PXA (A-PXA), 23 BRAF V600E mutant tumors (61%). CNVs were identified in all cases and most frequently involved chromosome 9 with homozygous CDKN2A/B deletion (n=33, 87%), a higher proportion than previously detected by comparative genomic hybridization (50-60%) (37). CDKN2A/B deletion was present in similar proportion of PXA (83%), A-PXA (93%), BRAF V600E (87%), and wild-type (87%) tumors. Whole chromosome gains/losses were frequent, including gains +7 (n=15), +2 (n=11), +5 (n=10), +21 (n=10), +20 (n=9), +12 (n=8), +15 (n=8) and losses -22 (n=11), -14 (n=7), -13 (n=5). Losses and copy-neutral loss of heterozygosity were significantly more common in A-PXA, involving chromosomes 22 (p=0.009) and 14 (p=0.03). Amplification of 8p and 12q was identified in a single tumor. Histologic grade was a robust predictor of overall survival (p=0.003), while other copy-number changes, including CDKN2A/B deletion, did not show significant association with survival. Distinct histologic patterns of anaplasia included increased mitotic activity in an otherwise classic PXA or associated with small cell, fibrillary, or epithelioid morphology, with loss of SMARCB1 expression in one case. In 10 cases, matched specimens were compared, including A-PXA with areas of distinct low- and high-grade morphology (n=2), matched primary/tumor recurrence (n=7), or both (n=1). Copy-number changes on recurrence/anaplastic transformation were complex and highly variable, from nearly identical profiles to numerous copy-number changes. Overall, we confirm CDKN2A/B deletion as key a feature of PXA not

    From January 1970 through December 1981, 469 patients with histologically or cytologically proven adenocarcinoma (AC) (349) and large cell carcinoma (LC) (120) of the lung were seen at the Department of Radiation Oncology, Medical College of Wisconsin Affiliated Hospitals. One quarter (126/469) of these patients had brain metastasis: 48 patients presented with brain metastasis and 78 patients subsequently developed brain metastasis. Brain was the dominant site of metastasis in 82 patients who received only cranial + thoracic irradiation; 37 patients (17 simultaneous, 20 metachronous) also required irradiation of other sites of metastasis. All 17 patients with LC, and 47/61 (77%) with AC who developed metachronous brain metastasis did so within one year. The cumulative probability of brain metastasis increased with survival to the levels predicted by autopsy studies. Therapeutic brain irradiation may result in long-term survival in patients with single organ brain metastasis. Since patients with AC and LC so frequently develop brain metastasis and the brain may be the only site of metastasis, prophylactic cranial irradiation may significantly reduce morbidity and mortality from these diseases.

    Relapse after anthracycline based combination chemotherapy is frequently seen in patients with aggressive non Hodgkin's Lymphomas (NHL), whereas complications such as secondary leukemia or solid tumor rarely occur. We report a patient with diffuse large cell (DLC) NHL and concurrent renal cancer, who developed acute myelofibrosis (AMF) later in the course of her disease. This 60-year-old female patient presented with pancytopenia and a right sided renal mass. Diagnostic work up revealed severe bone marrow infiltration by DLC NHL and renal cancer T1N0M0G2. Cytogenetic and molecular evaluation of bone marow cells showed three distinct clones, (a normal 46XX karyotype, a ringed chromosome 7 and a third clone with an enlarged chromosome 2 as well as several fragments). The patient underwent nephrectomy and eventually received 6 cycles of CHOP 14 chemotherapy. Anemia persisted followed by severe granulocytopenia and thrombocytopenia 6 weeks later. Repeated bone marrow biopsy showed absence of lymphoma and/or cancer metastasis, but massive myelofibrosis with an increased number of atypical megakaryocytes. Considering the short clinical course and the absence of hepatosplenomegaly AMF was diagnosed. The concurrence of three distinctneoplasms within a short period of time as well as the complex cytogenetic aberrations found in her bone marrow cells reflect a strong individual susceptibility to malignant disease in this patient.

    Large cell neuroendocrine carcinoma (LCNEC) of the ovary is a rare diagnosis and only a few dozen cases have been reported in the literature. It is characterized by large pleiomorphic cells with large round or oval nuclei, presence of mitoses and staining for neuroendocrine (NE) markers such as chromogranin A, synaptophysin, neuron specific enolase. This editorial gives a brief overview of this histologic type of ovarian carcinomas. LCNEC of the ovary is a pathologic entity that may not be diagnosed purely on clinical grounds due to the similarity of its clinical features with those of the more common epithelial ovarian cancers. Nevertheless the diagnosis is worth-making from a practical point of view in order to consider treatments tailored towards the NE component if it is dominant or it becomes dominant during the natural evolution of the disease. Establishment of an international tumor registry with an accompanying tumor tissue bank of ovarian LCNEC could be a means of obtaining further knowledge on clinical characteristics and advance research on this rare entity. This will further inform on treatment strategies and could identify future molecular treatment targets.

    Intravascular large cell lymphoma (IVLCL) is a rare disease characterized by proliferation of malignant lymphocytes within the small blood vessel lumens. The association of IVLCL with autoimmune hemolytic anemia (AIHA) has been described in a single case report, but the true prevalence of this co-occurrence is not known because of declining autopsy rates. Here, we report a case of a 41-year-old woman who carried a diagnosis of AIHA for 2 years, with repeated hemolytic episodes that were initially well controlled with immunomodulatory treatment. At her last presentation, the patient developed rapidly progressive neurologic symptoms and leukoencephalopathy on MRI; she died 4 weeks later with a clinical impression of thrombotic microangiopathy, a known complication of AIHA. At autopsy, the brain showed widespread platelet thrombi and intraparenchymal hemorrhages characteristic of this disorder. In addition, there was evidence of a clinically unsuspected IVLCL, most likely of B-cell lineage. This case illustrates a potential association between IVLCL and AIHA, highlights the need for broad differential diagnosis in cases with atypical disease presentation or progression, and underlines the importance of autopsy in establishing the full cause of morbidity and mortality.

    Lung cancer classification in small-cell and non-small-cell types was recently challenged by data on the differential efficacy of new cytotoxic agents in specific histotypes. An accurate histotype definition has therefore gained interest in both preoperative and surgical materials, but is a hard task especially in undifferentiated large-cell tumors lacking morphological signs of squamous or glandular differentiation. The responsiveness of these latter subtypes to new drugs apparently more selective for adenocarcinomas or squamous carcinomas is not fully understood, also due to the heterogeneity of diagnostic criteria for this tumor entity. Current immunohistochemical markers are not fully specific and new molecules are to be explored. On the basis of gene expression profiling data, reporting a remarkable differential expression of desmocollin-3 (a protein localized in desmosomal junctions of stratified epithelial) between adeno- and squamous cancers, we immunostained 62 cases of resected undifferentiated large-cell lung carcinomas for desmocollin-3 (and for TTF-1, p63 and mucin stain), to test its ability to identify a (residual) squamous phenotype, if present. Desmocollin-3 was expressed in almost half of the undifferentiated large-cell cancers and was mutually exclusive with TTF-1 (positive in 39%; the remaining 18 % of cases was double negative). Special large-cell carcinoma variants expressed desmocollin-3 in 6 of 6 basaloid, 7 of 12 clear-cell types, again mutually exclusive with TTF-1 expression. None of seven sarcomatoid carcinomas reacted for either marker. In 31 cytological samples diagnosed as 'non-small-cell lung carcinoma', desmocollin-3 was again mutually exclusive with TTF-1 and stained all squamous carcinomas, 1 of 19 adenocarcinoma only, and 50% of large-cell carcinoma (all histologically confirmed). This combined morphophenotypic approach may represent a valid adjunct (for both surgical and cytological samples) in the selection of patients with

    The sonic hedgehog (Shh) pathway is highly activated in thyroid neoplasms and promotes thyroid cancer stem-like cell phenotype, but whether the Shh pathway regulates thyroid tumor cell motility and invasiveness remains unknown. Here, we report that the motility and invasiveness of two anaplastic thyroid tumor cell lines, KAT-18 and SW1736, were inhibited by two inhibitors of the Shh pathway (cyclopamine and GANT61). Consistently, the cell motility and invasiveness was decreased by Shh and Gli1 knockdown, and was increased by Gli1 overexpression in KAT-18 cells. Mechanistic studies revealed that Akt and c-Met phosphorylation was decreased by a Gli1 inhibitor and by Shh and Gli1 knockdown, but was increased by Gli1 overexpression. LY294002, a PI-3 kinase inhibitor, and a c-Met inhibitor inhibited the motility and invasiveness of Gli1-transfected KAT-18 cells more effectively than the vector-transfected cells. Knockdown of Snail, a transcription factor regulated by the Shh pathway, led to decreased cell motility and invasiveness in KAT-18 and SW1736 cells. However, key epithelial-to-mesenchymal transition (EMT) markers including E-cadherin and vimentin as well as Slug were not affected by cyclopamine and GANT61 in either SW1736 or WRO82, a well differentiated follicular thyroid carcinoma cell line. Our data suggest that the Shh pathway-stimulated thyroid tumor cell motility and invasiveness is largely mediated by AKT and c-Met activation with little involvement of EMT.

    The tyrosine kinase receptor anaplastic lymphoma kinase (ALK) and its ligand, the growth factor pleiotrophin (PTN), are highly expressed during the development of the nervous system and have been implicated in the malignant progression of different tumor types. Here, we describe human single-chain variable fragment (scFv) antibodies that target the ligand-binding domain (LBD) in ALK and show the effect in vitro and in vivo. The ALK LBD was used as a bait in a yeast two-hybdrid system to select human scFv from a library with randomized complementarity-determining region 3 domains. Surface plasmon resonance showed high-affinity binding of the selected scFv. The anti-ALK scFv competed for binding of PTN to ALK in intact cells and inhibited PTN-dependent signal transduction through endogenous ALK. Invasion of an intact endothelial cell monolayer by U87MG human glioblastoma cells was inhibited by the anti-ALK scFv. In addition, the growth of established tumor xenografts in mice was reversed after the induction of the conditional expression of the anti-ALK scFv. In archival malignant brain tumors expression levels of ALK and PTN were found elevated and appear correlated with poor patient survival. This suggests a rate-limiting function of the PTN/ALK interaction that may be exploited therapeutically. PMID:19633684

    Objectives: We aimed to study the potential clinical relevance of 9p allelic loss, with or without copy number variation, in 1p/19q codeleted anaplastic oligodendroglial tumors (AOTs). Methods: This study enrolled 216 patients with 1p/19q codeleted AOT. The prognostic value of 9p allelic loss was investigated using a French nation-wide prospective registry, POLA (prise en charge des tumeurs oligodendrogliales anaplasiques) and high-density single nucleotide polymorphism arrays. We validated our results using the Repository of Molecular Brain Neoplasia Data (REMBRANDT) dataset. Results: The minimal common region of allelic loss in chromosome arm 9p was 9p21.3. Allelic loss of 9p21.3, detected in 41.7% of tumors, was associated with shorter progression-free and overall survival rates in univariate (p = 0.008 and p < 0.001, respectively) and multivariate analyses (p = 0.009 and p = 0.009, respectively). This finding was validated in the REMBRANDT dataset in univariate and multivariate analysis (p = 0.01 and p = 0.01, respectively). Conclusion: Our study highlights a novel potential prognostic biomarker in 1p/19q codeleted AOT. Further prospective studies are warranted to investigate our finding. PMID:26385879

    The integrated diagnosis of anaplastic oligodendroglioma, IDH mutant and 1p/19q co-deleted, grade III (O3(id) ) is a histomolecular entity that WHO 2016 classification distinguished from other diffuse gliomas by specific molecular alterations. In contrast, its cell portrait is less well known. The present study is focused on intertumor and intratumor, cell lineage-oriented, heterogeneity in O3(id) . Based on pathological, transcriptomic and immunophenotypic studies, a novel subgroup of newly diagnosed O3(id) overexpressing neuronal intermediate progenitor (NIP) genes was identified. This NIP overexpression pattern in O3(id) is associated with: (i) morphological and immunohistochemical similarities with embryonic subventricular zone, (ii) proliferating tumor cell subpopulation with NIP features including expression of INSM1 and no expression of SOX9, (iii) mutations in critical genes involved in NIP biology and, (iv) increased tumor necrosis. Interestingly, NIP tumor cell subpopulation increases in O3(id) recurrence compared with paired newly diagnosed tumors. Our results, validated in an independent cohort, emphasize intertumor and intratumor heterogeneity in O3(id) and identified a tumor cell subpopulation exhibiting NIP characteristics that is potentially critical in oncogenesis of O3(id) . A better understanding of spatial and temporal intratumor cell heterogeneity in O3(id) will open new therapeutic avenues overcoming resistance to current antitumor treatments.

    Information on gene alterations associated to poorly differentiated (PDTC) and anaplastic thyroid carcinomas (ATC) is scarce. Using human cancer cell lines as a tool for gene discovery, we performed a cytogenetic and oligo-array analysis in five new cell lines derived from two PDTC and three ATC. In PDTC we evidenced, as important, the involvement of the MAPK/ERK kinase pathway, and downregulation of a group of suppressor genes that include E-cadherin. In ATC, downregulation of a specific group of oncosuppressor genes was also observed. Our ATC cell lines presented chromosomal markers of gene amplification, and we were able to identify for the first time the nature of the involved amplicon target genes. We found that the main molecular differences between the two cell line types were related to signal transduction pathways, cell adhesion and motility process. TaqMan experiments performed for five amplicon target genes and for two genes, which allowed a clear distinction between ATC and PDTC: CDH13 and PLAU corroborated array results, not only in the cell lines, but also in an additional set of primary 14 PDTC and three ATC. We suggest that our findings may represent new tools for the development of more effective therapies to the hitherto untreatable ATC.

    MicroRNAs (miRNAs) play important roles in the pathogenesis of many types of cancers by negatively regulating gene expression at posttranscriptional level. However, the role of microRNAs in anaplastic thyroid carcinoma (ATC), has remained elusive. Here, we identified that miR-4295 promotes ATC cell proliferation by negatively regulates its target gene CDKN1A. In ATC cell lines, CCK-8 proliferation assay indicated that the cell proliferation was promoted by miR-4295, while miR-4295 inhibitor significantly inhibited the cell proliferation. Transwell assay showed that miR-4295 mimics significantly promoted the migration and invasion of ATC cells, whereas miR-4295 inhibitors significantly reduced cell migration and invasion. luciferase assays confirmed that miR-4295 directly bound to the 3'untranslated region of CDKN1A, and western blotting showed that miR-4295 suppressed the expression of CDKN1A at the protein levels. This study indicated that miR-4295 negatively regulates CDKN1A and promotes proliferation and invasion of ATC cell lines. Thus, miR-4295 may represent a potential therapeutic target for ATC intervention. - Highlights: • miR-4295 mimics promote the proliferation and invasion of ATC cells. • miR-4295 inhibitors inhibit the proliferation and invasion of ATC cells. • miR-4295 targets 3′UTR of CDKN1A in ATC cells. • miR-4295 negatively regulates CDKN1A in ATC cells.

    Abstract Multifocal cerebral gliomas (MCGs) represent approximately 10% of gliomas and are frequently mistaken as metastases of an unknown primary cancer site. Most MCGs are glioblastomas with <4 lesions supratentorially, and are lack of typical symptoms and special detections. Through a rare MCG case, we aim to present this rarity and emphasize the need to correctly diagnose multiple intracranial lesions using a variety of diagnostic modalities to ensure that the patient receives proper treatment. We present a case of multifocal cerebral anaplastic astrocytomas with a total of 8 lesions located in the left frontal lobe and invading the lateral ventricle, presenting with dysphasia and phantosmia. The disease course, including diagnosis and treatment, is presented and analyzed in detail. The pertinent literature is reviewed regarding this uncommon entity. After an initial impression of brain metastasis from lung cancer because of the magnetic resonance imaging (MRI) resemblance and history of chronic bronchitis, we were able to use positron emission tomography (PET) and excisional biopsy to get the final diagnosis. After 10 months, the patient's overall condition deteriorated and succumbed to his disease. MCGs are easy to be misdiagnosed as metastatic diseases. In addition to MRI, PET adds more biochemical and molecular information and is helpful in the differentiation. Although uncommon, if multiple lesions are present in various locations in the hemispheres, MCG should be kept in mind. PMID:25997068

    The anaplastic lymphoma kinase (ALK) fusion oncogene is observed in 3%–5% of non-small cell lung cancer (NSCLC). Crizotinib and ceritinib, a next-generation ALK tyrosine kinase inhibitor (TKI) active against crizotinib-refractory patients, are clinically available for the treatment of ALK-rearranged NSCLC patients, and multiple next-generation ALK-TKIs are currently under clinical evaluation. These ALK-TKIs exhibit robust clinical activity in ALK-rearranged NSCLC patients; however, the emergence of ALK-TKI resistance restricts the therapeutic effect. To date, various secondary mutations or bypass pathway activation-mediated resistance have been identified, but large parts of the resistance mechanism are yet to be identified. Here, we report the discovery of p-glycoprotein (P-gp/ABCB1) overexpression as a ceritinib resistance mechanism in ALK-rearranged NSCLC patients. P-gp exported ceritinib and its overexpression conferred ceritinib and crizotinib resistance, but not to PF-06463922 or alectinib, which are next-generation ALK inhibitors. Knockdown of ABCB1 or P-gp inhibitors sensitizes the patient-derived cancer cells to ceritinib, in vitro and in vivo. P-gp overexpression was identified in three out of 11 cases with in ALK-rearranged crizotinib or ceritinib resistant NSCLC patients. Our study suggests that alectinib, PF-06463922, or P-gp inhibitor with ceritinib could overcome the ceritinib or crizotinib resistance mediated by P-gp overexpression. PMID:26870817

    The mechanisms of malignant cell transformation mediated by the oncogenic, chimeric nucleophosmin/anaplastic lymphoma kinase (NPM/ALK) tyrosine kinase remain only partially understood. Here we report that the NPM/ALK-carrying T cell lymphoma (ALK+TCL) cells secrete IL-10 and TGF-β and express FoxP3, indicating their T regulatory (Treg) cell phenotype. The secreted IL-10 suppresses proliferation of normal immune, CD3/CD28-stimulated peripheral blood mononuclear cells and enhances viability of the ALK+TCL cells. The Treg phenotype of the affected cells is strictly dependent on NPM/ALK expression and function as demonstrated by transfection of the kinase into BaF3 cells and inhibition of its enzymatic activity and expression in ALK+TCL cells. NPM/ALK, in turn, induces the phenotype through activation of its key signal transmitter, signal transducer and activator of transcription 3 (STAT3). These findings identify a mechanism of NPM/ALK-mediated oncogenesis based on induction of the Treg phenotype of the transformed CD4+ T cells. These results also provide an additional rationale to therapeutically target the chimeric kinase and/or STAT3 in ALK+TCL. PMID:16766651

    Chemotherapy is one of the most effective forms of cancer treatment and has been used in the treatment of various malignant tumors. We have gained significant insight into the mechanisms of chemoresistance but the details of the molecular mechanisms remain unclear. In the present study, we found that tripartite motif 8 (TRIM8) expression was downregulated in anaplastic thyroid cancer (ATC) tissues and cell lines. This downregulation of TRIM8 was significantly correlated with the upregulation of miR-182 in human ATC tissues. Bioinformatic analysis and luciferase reporter assays identified TRIM8 as a direct target of miR-182 in ATC. A functional assay using an MTT assay and colony formation showed that miR-182 induced cellular growth by repressing TRIM8 expression. Additionally, overexpressed miR-182 contributed to the chemoresistance of ATC cells by the repression of TRIM8 expression. In conclusion, these results demonstrate that miR-182/TRIM8 may be a therapeutic target for the treatment of chemoresistant human thyroid papillary cancer. PMID:28280352

    The growing incidences of secondary malignancies in long-term survivors of childhood leukemia following allogeneic bone marrow transplantation (alloBMT) are increasingly being reported. Among the late complications of conventional myeloablative alloBMT, the occurrence of secondary malignant solid tumors is of major concern. Secondary malignant and benign brain tumors such as astrocytoma, meningioma and glioblastoma have been described in long-term survivors of conventional myeloablative alloBMT. Here we report a case of secondary anaplastic oligoastrocytoma that developed 7 years after matched unrelated alloBMT for relapsing childhood acute myeloid leukemia (AML) with CNS involvement. Although isolated CNS relapse of primary leukemia following alloBMT is not uncommon, it is important to identify and define potential risk factors that may lead to the development of secondary brain tumors in children who received high-dose chemotherapy and irradiation prior to alloBMT presenting with progressive neurological symptoms and to differentiate them from leukemia relapse with CNS involvement.

    Williams syndrome is a rare congenital developmental disorder characterized by a constellation of distinctive facial dysmorphisms, mental retardation, cardiovascular anomalies, infantile hypercalcemia, delayed developmental milestones, dental and musculoskeletal anomalies and distinctive personality traits. A majority of patients with Williams syndrome exhibit a hemizygous micro-deletion of chromosome 7q11.23, which is the locus of some 20-30 genes including the ELN gene that encodes the structural protein elastin. Chromosome 7q contains putative tumor suppressor genes and is one of the chromosomes that are frequently involved in chromosomal aberrations in human malignancies. A paucity of tumors (three) has been reported in the literature to occur in patients with Williams syndrome. We report a case of anaplastic oligodendroglioma that occurred in a 31-year-old man with Williams syndrome. Mutational profiling by loss of heterozygosity analysis using a panel of polymorphic micro-satellite markers indicated combined deletion of chromosome 1p and 19q. We draw attention to this apparently rare or possibly under-reported occurrence of tumors in patients with Williams syndrome and suggest that Central Nervous System [CNS] tumors be considered as differential diagnoses in such patients when they present with unanticipated neurologic symptoms that are not attributable to those commonly associated with Williams syndrome.

  12. Heat Shield Employing Cured Thermal Protection Material Blocks Bonded in a Large-Cell Honeycomb Matrix

    A document describes a new way to integrate thermal protection materials on external surfaces of vehicles that experience the severe heating environments of atmospheric entry from space. Cured blocks of thermal protection materials are bonded into a compatible, large-cell honeycomb matrix that can be applied on the external surfaces of the vehicles. The honeycomb matrix cell size, and corresponding thermal protection material block size, is envisioned to be between 1 and 4 in. (.2.5 and 10 cm) on a side, with a depth required to protect the vehicle. The cell wall thickness is thin, between 0.01 and 0.10 in. (.0.025 and 0.25 cm). A key feature is that the honeycomb matrix is attached to the vehicle fs unprotected external surface prior to insertion of the thermal protection material blocks. The attachment integrity of the honeycomb can then be confirmed over the full range of temperature and loads that the vehicle will experience. Another key feature of the innovation is the use of uniform-sized thermal protection material blocks. This feature allows for the mass production of these blocks at a size that is convenient for quality control inspection. The honeycomb that receives the blocks must have cells with a compatible set of internal dimensions. The innovation involves the use of a faceted subsurface under the honeycomb. This provides a predictable surface with perpendicular cell walls for the majority of the blocks. Some cells will have positive tapers to accommodate mitered joints between honeycomb panels on each facet of the subsurface. These tapered cells have dimensions that may fall within the boundaries of the uniform-sized blocks.

    A metastatic model for large-cell lymphoma/lymphosarcoma has been developed by sequential selection in vivo of the murine RAW117 cell line for enhanced liver metastasis or in vitro for loss of lectin-binding properties. The metastatic variants obtained from such selections show alterations in cell surface lectin-binding components, such as the wheat germ agglutinin (WGA)-reactive sialoglycoproteins. Detergent lysates from RAW117 cells were analyzed by polyacrylamide gel electrophoresis (PAGE) followed by reaction with /sup 125/I-labeled WGA. The (/sup 125/I)WGA became bound to a diffuse band of M/sub r/ 120,000-200,000 in the gels that overlapped with the major sialoglycoprotein band revealed by the periodate-sodium borotritide labeling. However, the (/sup 125/I)WGA reactivity diminished when gels were pretreated with mild acid to remove sialic acid in situ. The binding of (/sup 125/I)WGA to the glycoprotein(s) was greater in the high liver-colonizing RAW117--H10 subline than in the parental RAW117-P line. Another lectin with different saccharide specificity, Ricinus communis agglutinin I (RCA/sub I/), became bound to a similar class of sialoglycoproteins, as well as to glycoproteins of lower M/sub r/, but only when the gels were pretreated with mild acid to remove sialic acid. /sup 125/)WGA reactivity to the sialoglycoprotein components, before and after Smith degradation in situ, strongly suggests that the oligosaccharide back-bones are highly branched and asparagine-linked.

    Senescence in cancer cells acts as a tumor suppressor, whereas in fibroblasts enhances tumor growth. Senescence has been reported in tumor associated fibroblasts (TAFs) from a growing list of cancer subtypes. However, the presence of senescent TAFs in lung cancer remains undefined. We examined senescence in TAFs from primary lung cancer and paired control fibroblasts from unaffected tissue in three major histologic subtypes: adenocarcinoma (ADC), squamous cell carcinoma (SCC) and large cell carcinoma (LCC). Three independent senescence markers (senescence-associated beta-galactosidase, permanent growth arrest and spreading) were consistently observed in cultured LCC-TAFs only, revealing a selective premature senescence. Intriguingly, SCC-TAFs exhibited a poor growth response in the absence of senescence markers, indicating a dysfunctional phenotype rather than senescence. Co-culturing normal fibroblasts with LCC (but not ADC or SCC) cancer cells was sufficient to render fibroblasts senescent through oxidative stress, indicating that senescence in LCC-TAFs is driven by heterotypic signaling. In addition, senescent fibroblasts provided selective growth and invasive advantages to LCC cells in culture compared to normal fibroblasts. Likewise, senescent fibroblasts enhanced tumor growth and lung dissemination of tumor cells when co-injected with LCC cells in nude mice beyond the effects induced by control fibroblasts. These results define the subtype-specific aberrant phenotypes of lung TAFs, thereby challenging the common assumption that lung TAFs are a heterogeneous myofibroblast-like cell population regardless of their subtype. Importantly, because LCC often distinguishes itself in the clinic by its aggressive nature, we argue that senescent TAFs may contribute to the selective aggressive behavior of LCC tumors.

    Background Recent research into lung cancer‐related driver genes has identified a distinctive molecular subtype of non‐small cell lung cancer (NSCLC) – anaplastic lymphoma kinase (ALK)‐positive NSCLC. We evaluated the clinical features and survival rates of ALK‐positive lung adenocarcinoma patients who had undergone surgery but had not received ALK inhibitor therapy, along with the characteristics of patients with distant metastases. Methods Clinical data of 40 patients with ALK‐positive, postsurgical lung adenocarcinoma were retrospectively analyzed. Relationships between the patients’ clinical characteristics, distant metastases, and their disease‐free survival (DFS) and overall survival (OS) rates were assessed. Results Most patients were relatively young, never‐smokers, had peripheral tumors, and the tumors were either moderately or poorly differentiated. The most common organ of distant metastases was the brain. The median time from surgery to brain metastasis was 17.2 months. The median OS following brain metastasis was 9.4 months. DFS in patients with early stage disease, peripheral tumors, no lymph node metastases, and treated with adjuvant therapy was significantly longer than for those with late stage disease (P = 0.015), central tumors (P = 0.000), lymph node metastases (P = 0.026), and not treated with adjuvant therapy (P = 0.000). Patients with early stage disease, peripheral tumors, and treated with adjuvant therapy obtained markedly longer OS than those with late stage disease (P = 0.021), central tumors (P = 0.003), and not treated with adjuvant therapy (P = 0.006). Conclusion Patients with ALK‐positive surgically resected lung adenocarcinoma have distinctive clinical characteristics. The brain is the most common site of extrapulmonary metastasis. Survival is associated with stage, tumor location, and the administration of adjuvant therapy. PMID:27779369

    Numerous studies have investigated the roles played by various genes and microRNAs (miRNAs) in neoplasms, including anaplastic astrocytoma (AA). However, the specific regulatory mechanisms involving these genes and miRNAs remain unclear. In the present study, associated biological factors (miRNAs, transcription factors, target genes and host genes) from existing studies of human AA were combined methodically through the interactions between genes and miRNAs, as opposed to studying one or several. Three regulatory networks, including abnormally expressed, related and global networks were constructed with the aim of identifying significant gene and miRNA pathways. Each network is composed of three associations between miRNAs targeted at genes, transcription factors (TFs) regulating miRNAs and miRNAs located on their host genes. Among these, the abnormally expressed network, which involves the pathways of previously identified abnormally expressed genes and miRNAs, partially indicated the regulatory mechanism underlying AA. The network contains numerous abnormal regulation associations when AA emerges. By modifying the abnormally expressed network factors to a normal expression pattern, the faulty regulation may be corrected and tumorigenesis of AA may be prevented. Certain specific pathways are highlighted in AA, for example PTEN which is targeted by miR-21 and miR-106b, regulates miR-25 which in turn targets TP53. PTEN and miR-21 have been observed to form feedback loops. Furthermore, by comparing and analyzing the pathway predecessors and successors of abnormally expressed genes and miRNAs in three networks, similarities and differences of regulatory pathways may be identified and proposed. In summary, the present study aids in elucidating the occurrence, mechanism, prevention and treatment of AA. These results may aid further investigation into therapeutic approaches for this disease.

    Anaplastic thyroid carcinoma (ATC) is the most aggressive malignancy in thyroid cancers. Resistance to current therapies is still a challenge. MicroRNAs are a class of small non-coding RNAs, regulating gene expression. MiR-21 is an oncomiR that is overexpressed in nearly all cancers including ATC. Accumulating evidence suggested that miR-21 has a role in cancer stemness state, apoptosis, cell cycle progression, and differentiation. Therefore, we evaluated the application of Off-miR-21 to sequester the microRNA for therapeutic purposes on ATC cell lines. In this study, C643 and SW1736 were transducted by hsa-miR-21 antagomir (Off-miR-21). PTEN gene expression was performed as a known target of miR-21. Stemness state in cancer stem cells (CSCs) was evaluated by the changes of CSC biomarkers including Oct-4 and ABCG2. Apoptosis was assessed by PDCD4 and Mcl-1 gene expression and flow cytometry. Sodium/iodide symporter (NIS) and thyroglobulin (TG) were measured as ATC differentiation markers. In addition, cell cycle progression was investigated via the alterations of p21 gene expression and flow cytometry. Specific downregulation of miR-21 induced the differentiation and apoptosis in C643 and SW1736. Inversely, the treatment inhibited stemness state and cell cycle progression. Knockdown of miR-21 significantly increased the expression of PDCD4, p21, NIS, and TG while leading to decreased expression of Oct-4, ABCG2, and Mcl-1.Taken together, the results suggest that miR-21, as an oncomiR, has a role not only in stemness state but also in tumor growth, differentiation, and apoptosis. Hence, suppression of miR-21 could pave the way for ATC therapy.

    This study assesses the controversial role of temozolomide (TMZ) concurrent with adjuvant radiation (RT) in patients with anaplastic astrocytoma (AA). The impact of isocitrate dehydrogenase (IDH) status on therapy and outcomes is also examined. All adult patients diagnosed with AA from 2001 to 2011 and treated with standard doses of adjuvant RT were identified retrospectively for clinical data extraction. IDH status was determined by IDH1-R132H immunostain and sequencing for other mutations in IDH1/IDH2. Cumulative survival probabilities were estimated using the Kaplan-Meier method. Cox proportional hazards regression models were fit for univariable/multivariable analyses. 136 patients had received concurrent TMZ while 29 had not. Of these, IDH status was determined on 114 and 27 patients, respectively. On univariable analysis, improved five-year survival was independently associated with concurrent TMZ (46.2 vs. 29.3%, p = 0.02) and IDH mutation (78.9 vs. 22.0%, p < 0.001). IDH mutation was additionally associated with a greater likelihood of extensive resection possibly secondary to a more favorable tumor location. Gross total/subtotal resections also led to improved survival when compared to biopsy alone on univariable analysis. On multivariable analysis, the association with five-year survival persisted for both concurrent TMZ and IDH mutation, but not with extent of surgery. Both IDH mutation and concurrent TMZ are associated with improved five-year survival in patients with AA who are receiving adjuvant RT. Secondarily, the association between five-year survival and extent of resection is lost on multivariable analysis. This suggests a possible association between IDH mutation, tumor location and consequent resectability.

    Anaplastic thyroid carcinoma (ATC) originates from completely undifferentiated cells, and is the most lethal type of thyroid-derived tumor. Numerous microRNAs have significant roles in tumorigenesis by targeting relevant genes. The role of microRNA 146b (miR-146b) in ATC remains to be elucidated. In order to characterize the role of miR-146b in ATC, overexpression or interference of miR-146b was induced in ATC cell lines, and cell proliferation and migration were evaluated. The potential targets of miR-146b were searched in the Gene Expression Omnibus database for ATC and matched non-tumor control samples. The expression level of potential targets was detected following overexpression or interference of miR-146b in ATC cell lines. In the present study, cell proliferation was promoted when overexpression of miR-146b was induced in ATC, and inhibited when interference of miR-146b was induced, which indicated that miR-146b affects the proliferation of ATC cells in vitro. In addition, cell migration of ATC was also affected by miR-146b. During the search for potential targets of miR-146b in ATC, p21 (also known as p21Waf1/Cip1 or CDKN1A) was noted for its role in cell cycle progression and tumor pathogenesis. The expression level of p21 was influenced by the level of miR-146b, and the results of the present study demonstrated that the level of p21 was increased when FRO cells were transformed with miR-146b mimic, and p21 was downregulated when FRO cells transformed with anti-miR-146b. In conclusion, p21 may participate in the regulation of ATC cell proliferation by miR-146b. PMID:27602131

    Granulocyte colony-stimulating factor (G-CSF)-producing pancreatic tumors are extremely rare. These tumors have an aggressive clinical course and no established treatment. Here, we report an autopsy case of G-CSF-production in pancreatic anaplastic carcinoma (PAC). A 72-year-old woman presented with a large pancreatic head mass and multiple liver metastases. Laboratory data showed leukocytosis (leukocyte count 113.3 × 10(3) /µL) and high serum G-CSF levels (441 pg/mL; normal range: <39.0 pg/mL). The ascitic fluid was submitted to our pathology laboratory at initial diagnosis. Cytopathology showed that smears from the ascitic fluid were highly cellular and contained numerous malignant cells, mainly in loose groupings. Occasional pseudoglandular formations and giant cells were also present. The malignant cells were round, and no spindle-shaped cells were visible. The nuclei were round to ovoid with coarsely granular chromatin and large prominent nucleoli. Upon immunocytochemistry, tumor cells were positive for G-CSF and vimentin; there was no E-cadherin expression. Histopathological examination of the tumor showed a mixed composition of adenocarcinomatous and sarcomatous regions. Upon immunohistochemistry, both components were positive for G-CSF. Few CD34-positive myeloblasts were observed in the bone marrow. Thus, we diagnosed this as a case of G-CSF production in PAC with leukocytosis. To the best of our knowledge, this is the first report on G-CSF expression immunocytochemically confirmed in PAC. Diagn. Cytopathol. © 2017 Wiley Periodicals, Inc.

    The present work investigates whether computer-assisted techniques can contribute any significant information to the characterization of astrocytic tumor aggressiveness. Two complementary computer-assisted methods were used. The first method made use of the digital image analysis of Feulgen-stained nuclei, making it possible to compute 15 morphonuclear and 8 nuclear DNA content-related (ploidy level) parameters. The second method enabled the most discriminatory parameters to be determined. This second method is the Decision Tree technique, which forms part of the Supervised Learning Algorithms. These two techniques were applied to a series of 250 supratentorial astrocytic tumors of the adult. This series included 39 low-grade (astrocytomas, AST) and 211 high-grade (47 anaplastic astrocytomas, ANA, and 164 glioblastomas, GBM) astrocytic tumors. The results show that some AST, ANA and GBM did not fit within simple logical rules. These "complex" cases were labeled NC-AST, NC-ANA and NC-GBM because they were "non-classical" (NC) with respect to their cytological features. An analysis of survival data revealed that the patients with NC-GBM had the same survival period as patients with GBM. In sharp contrast, patients with ANA survived significantly longer than patients with NC-ANA. In fact, the patients with ANA had the same survival period as patients who died from AST, while the patients with NC-ANA had a survival period similar to those with GBM. All these data show that the computer-assisted techniques used in this study can actually provide the pathologist with significant information on the characterization of astrocytic tumor aggressiveness.

    Anaplastic thyroid cancer (ATC), one of the most aggressive solid tumors, is characterized by rapid tumor growth and severe metastasis to other organs. Owing to the lack of effective treatment options, ATC has a mortality rate of ∼100% and median survival of less than 5 months. RNAi nanotechnology represents a promising strategy for cancer therapy through nanoparticle (NP) -mediated delivery of RNAi agents (e.g., siRNA) to solid tumors for specific silencing of target genes driving growth and/or metastasis. Nevertheless, the clinical success of RNAi cancer nanotherapies remains elusive in large part because of the suboptimal systemic siRNA NP delivery to tumors and the fact that tumor heterogeneity produces variable NP accumulation and thus, therapeutic response. To address these challenges, we here present an innovative theranostic NP platform composed of a near-infrared (NIR) fluorescent polymer for effective in vivo siRNA delivery to ATC tumors and simultaneous tracking of the tumor accumulation by noninvasive NIR imaging. The NIR polymeric NPs are small (∼50 nm), show long blood circulation and high tumor accumulation, and facilitate tumor imaging. Systemic siRNA delivery using these NPs efficiently silences the expression of V-Raf murine sarcoma viral oncogene homolog B (BRAF) in tumor tissues and significantly suppresses tumor growth and metastasis in an orthotopic mouse model of ATC. These results suggest that this theranostic NP system could become an effective tool for NIR imaging-guided siRNA delivery for personalized treatment of advanced malignancies. PMID:27342857

    Purpose: To analyze the durability and toxicity of radiotherapeutic local ablative therapy (LAT) applied to extra-central nervous system (eCNS) disease progression in anaplastic lymphoma kinase-positive non-small cell lung cancer (NSCLC) patients. Methods and Materials: Anaplastic lymphoma kinase-positive NSCLC patients receiving crizotinib and manifesting ≤4 discrete sites of eCNS progression were classified as having oligoprogressive disease (OPD). If subsequent progression met OPD criteria, additional courses of LAT were considered. Crizotinib was continued until eCNS progression was beyond OPD criteria or otherwise not suitable for further LAT. Results: Of 38 patients, 33 progressed while taking crizotinib. Of these, 14 had eCNS progression meeting OPD criteria suitable for radiotherapeutic LAT. Patients with eCNS OPD received 1-3 courses of LAT with radiation therapy. The 6- and 12-month actuarial local lesion control rates with radiation therapy were 100% and 86%, respectively. The 12-month local lesion control rate with single-fraction equivalent dose >25 Gy versus ≤25 Gy was 100% versus 60% (P=.01). No acute or late grade >2 radiation therapy-related toxicities were observed. Median overall time taking crizotinib among those treated with LAT versus those who progressed but were not suitable for LAT was 28 versus 10.1 months, respectively. Patients continuing to take crizotinib for >12 months versus ≤12 months had a 2-year overall survival rate of 72% versus 12%, respectively (P<.0001). Conclusions: Local ablative therapy safely and durably eradicated sites of individual lesion progression in anaplastic lymphoma kinase-positive NSCLC patients receiving crizotinib. A dose–response relationship for local lesion control was observed. The suppression of OPD by LAT in patients taking crizotinib allowed an extended duration of exposure to crizotinib, which was associated with longer overall survival.

    The primary cutaneous T-cell lymphomas (CTCL) represent a clonal T-lymphocyte proliferation infiltrating the skin. CD30+T-cell lymphomas present clinically as nodules with a diameter between 1 and 15 cm, mostly in elderly patients. The role of the CD30 molecule in patients suffering from T-cell lymphomas is not completely clear yet. The signal transduction pathway which includes CD30 seems to play a key role in tumor progression. In certain forms of T-cellular lymphomas, the interaction between CD30/CD30-ligand is able to provoke apoptosis of the “tumor lymphocytes”. The modern conceptions of the pathogenesis of T-cell lymphomas include disorders in the pathways involved in programmed cellular death and disregulation in the expression of certain of its regulatory molecules. We are presenting an unusual case of a female patient with a primary cutaneous form of CD30+/ALK− anaplastic large T-cell lymphoma. Upon the introduction of systemic PUVA, (psoralen plus ultraviolet light radiation) combined with beam therapy, a complete remission could be noticed. Eight months later, we observed a local recurrence, which was overcome by CHOP chemotherapy (Cyclophosphamide, Hydroxydaunorubicin (Doxorubicin), Vincristin (Oncovin®), Predniso(lo)n). Six months later, new cutaneous lesions had been noticed again. A new therapeutic hope for the patients with anaplastic large CTCL is actually based on the influence of the activity of the different apoptotic pathways. Death ligands, including tumor necrosis factor (TNF)-α, CD95L/FasL, and TRAIL, mediate also some important safeguard mechanisms against tumor growth in patients with CD30+ cutaneous anaplastic large T-cell lymphomas and critically contribute to lymphocyte homeostasis.

    Anaplastic lymphoma kinase (ALK) encodes a receptor tyrosine kinase, and ALK gene rearrangement (ALK+) is implicated in the oncogenesis of non-small cell lung carcinomas (NSCLCs), especially adenocarcinomas. The ALK inhibitor crizotinib was approved in August 2011 by the US Food and Drug Administration (FDA) for treating late-stage NSCLCs that are ALK+, with a companion fluorescent in situ hybridization (FISH) test using the Vysis ALK Break Apart FISH Probe Kit. This review covers pertinent issues in ALK testing, including approaches to select target patients for the test, pros and cons of different detection methods, and mechanisms as well as monitoring of acquired crizotinib resistance in ALK+ NSCLCs.

    INTRODUCTION: Recent randomized trials showed that highly extent of resection (EOR) and PCV chemoradiotherapy had therapeutic long-term efficacy to anaplastic glioma (AG). From 2000, we have consistently enforced extensive removal and ACNU-based chemoradiotherapy for AG. We report retrospective clinical results of a single institution. METHODS: We reviewed 147 cases of primary AG between 2000 and 2011 (Male : Female = 94:53, average age; 43.9 year-old). 69 were anaplastic astrocytoma (41%), 43 were anaplastic oligoastrocytoma (29%), and 44 were anaplastic oligodendroglioma (30%). The intraoperative MRI was performed in 133 cases (90%), and awake surgery was performed in 58 cases (39%). Gross-total removal was 46 (31%), partial removal was 89 (61%), and biopsy was 12 (8%) (average; 83%, median; 95%). After resection, 60 Gy radiotherapy and ACNU or PAV chemotherapy were performed. The average Mib-1 index was 15%. The mean observation periods were 57 months and 95% follow-up rate. RESULTS: Overall survival (OS) wasn't reached median. The 3y-OS was 82%, 5y-OSs was 72%, and 10y-OS was 66%. There was no statistical significance among AA, AOA, AO (5y-OS; 64%, 79%, 77%). The each 5 years survival rate of gross-total resection, partial resection, and biopsy were 83%, 70%, 39%, and there was statistical significance (P = 0.0024). Extent of resection (EOR) correlated OS in AA (P = 0.02) but not in oligodendroglial subtypes (P = 0.6). Statistical significant factors were EOR (P = 0.0024) and Mib-1 index (P = 0.013). The significant factors in multi variable analysis were EOR (more than 95% or not, HR 2.5) and Mib-1 index (more than 13% or not, HR 2.3). The median PFS was 8.3, and 5y-PFS was 59%,and 10y-PFS was 45%. CONCLUSION: Our long-term clinical results of AG treated with extensive resection and ACNU-based chemoradiotherapy were better than previous reports. The EOR contributed better prognosis especially for AA.

    We report on a young woman with a left temporal diffuse low-grade glioma treated initially by a subtotal resection. A focal anaplastic area appeared 5years later and was treated by radiosurgery. A long-time stabilization was therefore obtained and lasted even after pregnancy, which is a known factor of faster tumour progression. This report shows that radiosurgery could be an option in the multimodal treatment of a selected group of patients with focal malignant transformation of diffuse low-grade glioma. It could permit long-term stabilization of the tumour without any other adjuvant treatment and without compromising the quality of life.

    The seeding of tumor through cerebrospinal fluid (CSF) from primary intracranial tumors is very rare, often goes undetected, and is usually identified only on autopsy. CSF cytology along with magnetic resonance imaging constitutes the standard approach of diagnosing this grave condition. Use of fluoro-2-deoxyglucose positron emission tomography/computed tomography (PET/CT) in indentifying spinal metastases from primary intracranial malignancies is very limited and has been reported in patients with metastatic glioblastoma multiforme and medulloblastomas. We present a rare case of metastatic anaplastic ependymoma to show the potentially clinically utility of PET/CT in diagnosing leptomeningeal or the so-called “drop” metastases. PMID:28242994

    Primary neuroendocrine tumors of the female genital tract have been described in the cervix, ovaries and uterus. Large cell neuroendocrine carcinoma (LCNC) of the uterine corpus is the least common and appears to behave the most aggressively. We report a rare case of a large cell neuroendocrine tumor of the endometrium. These tumors are not well characterized, unlike neuroendocrine tumors of the uterine cervix. Consequently, the optimal management remains still unclear. The treatment of our case consisted of surgery, radiotherapy, chemotherapy, and octreotide. Despite the aggressive treatment, the patient died of disease progression 12 months after the initial diagnosis. We discuss the diagnosis, prognosis, and treatment options for LCNC of the genital tract, and potential future therapeutics.

    Twelve examples of mixed small- and large-cell lymphoma (eight follicular, one follicular and diffuse, and three diffuse) were investigated morphometrically using plastic-embedded tissue in order to study nuclear characteristics of lymphocyte populations in this form of non-Hodgkin's lymphoma (NHL) and to test morphologic bases for current NHL classification systems. This study illustrates that there are many inaccuracies, illusions, and misconceptions in the morphologic criteria currently used to classify mixed small- and large-cell lymphoma. A principal finding was that lymphocyte nuclear profiles in mixed-cell lymphomas tend to be smaller in size (P less than .005) and more irregular in shape (P = .0001) than the morphologically similar counterparts in germinal centers of lymph nodes with reactive hyperplasia. Intercase comparison of mixed small- and large-cell lymphomas revealed a considerable range of mean nuclear area values, some of which were within the size range of normal, small lymphocytes. At the magnifications used for morphometric assessment, a high proportion of lymphocyte nuclear profiles had shallow invaginations, but only a limited number of profiles (4% to 14%) had deep (cleaved) indentations. Contrary to current definitions for this subtype of NHL, lymphocytes with "small" nuclei had the same proportion of the nuclear diameter occupied by nuclear invaginations as lymphocytes with "large" nuclei and, in fact, mean nuclear invagination depth was shallower in "small" nuclei than in "large" nuclei. Furthermore, regardless of whether it is nuclear area or shape that is evaluated, lymphocytes in mixed-cell lymphoma do not separate into two populations of small-cleaved and large noncleaved cells. Morphometry reveals that only four of the 12 examples of mixed small- and large-cell lymphoma had a proportion of the lymphocytes in the size range of fully transformed germinal center lymphocytes that exceeded 25%, and none of the cases approached 50% even

    To determine the receipt and impact of adjuvant therapy on overall survival (OS) for anaplastic astrocytoma (AA). Data were extracted from the National Cancer Data Base (NCDB). Chi square test, Kaplan-Meier method, and Cox regression models were employed in SPSS 22.0 (Armonk, NY: IBM Corp.) for data analyses. 4807 patients with AA diagnosed from 2004 to 2013 who underwent surgery were identified. 3243 (67.5 %) received adjuvant chemoRT, 525 (10.9 %) adjuvant radiotherapy (RT) alone, 176 (3.7 %) adjuvant chemotherapy alone and 863 (18.0 %) received no adjuvant therapy. Patients were more likely to receive adjuvant chemoRT if they were diagnosed in 2009-2013 (p = 0.022), were ≤ 50 years (p < 0.001), were male (p = 0.043), were Asian or White race (p < 0.001), had private insurance (p < 0.001), had income ≥$38,000 (p < 0.001), or underwent total resection (p < 0.003). Those who received adjuvant chemoRT had significantly better 5-year OS than the other adjuvant treatment types (41.8 % vs. 31.2 % vs. 29.8 % vs. 27.4 %, p < 0.001). This significant 5-year OS benefit was also observed regardless of age at diagnosis. Of those undergoing adjuvant chemoRT, those receiving ≥59.4 Gy had significantly better 5-year OS than those receiving <59.4 Gy (44.4 % vs. 25.9 %, p < 0.001). There was no significant difference in OS when comparing 59.4 Gy to higher RT doses. On multivariate analysis, receipt of adjuvant chemoRT, age at diagnosis, extent of disease, and insurance status were independent prognostic factors for OS. Adjuvant chemoRT is an independent prognostic factor for improved OS in AA and concomitant chemoRT should be considered for all clinically suitable patients who have undergone surgery for the disease.

    Background We previously noted that among atomic bomb survivors (ABS), the relative frequency of cases of adult papillary thyroid cancer (PTC) with chromosomal rearrangements (mainly RET/PTC) was significantly greater in those with relatively higher radiation exposure than those with lower radiation exposure. In contrast, the frequency of PTC cases with point mutations (mainly BRAFV600E) was significantly lower in patients with relatively higher radiation exposure than those with lower radiation exposure. We also found that among ABS, the frequency of PTC cases with no detectable gene alterations in RET, neurotrophic tyrosine kinase receptor 1 (NTRK1), BRAF, or RAS was significantly higher in patients with relatively higher radiation exposure than those with lower radiation exposure. However, in ABS with PTC, the relationship between the presence of the anaplastic lymphoma kinase (ALK) gene fused with other gene partners and radiation exposure has received little study. In this study, we tested the hypothesis that the relative frequency of rearranged ALK in ABS with PTC, and with no detectable gene alterations in RET, NTRK1, BRAF, or RAS, would be greater in those having relatively higher radiation exposures. Methods The 105 subjects in the study were drawn from the Life Span Study cohort of ABS of Hiroshima and Nagasaki who were diagnosed with PTC between 1956 and 1993. Seventy-nine were exposed (>0 mGy), and 26 were not exposed to A-bomb radiation. In the 25 ABS with PTC, and with no detectable gene alterations in RET, NTRK1, BRAF, or RAS, we examined archival, formalin-fixed, paraffin-embedded PTC specimens for rearrangement of ALK using reverse transcription–polymerase chain reaction and 5′ rapid amplification of cDNA ends (5′ RACE). Results We found rearranged ALK in 10 of 19 radiation-exposed PTC cases, but none among 6 patients with PTC with no radiation exposure. In addition, solid/trabecular-like architecture in PTC was closely associated with ALK

    Glucose transporter-1 (GLUT-1) is one of the major isoforms of the family of glucose transporter proteins that facilitates the import of glucose in human cells to fuel anaerobic metabolism. The present study was meant to determine the extent of the anaerobic/hypoxic state of the intratumoral microenvironment by staining for GLUT-1 in intracranial non-embolized typical (WHO grade I; n = 40), brain invasive and atypical (each WHO grade II; n = 38) and anaplastic meningiomas (WHO grade III, n = 6). In addition, GLUT-1 staining levels were compared with the various histological criteria used for diagnosing WHO grade II and III meningiomas, namely, brain invasion, increased mitotic activity and atypical cytoarchitectural change, defined by the presence of at least three out of hypercellularity, sheet-like growth, prominent nucleoli, small cell change and "spontaneous" necrosis. The level of tumor hypoxia was assessed by converting the extent and intensity of the stainings by multiplication in an immunoreactive score (IRS) and statistically evaluated. The results were as follows. (1) While GLUT-1 expression was found to be mainly weak in WHO grade I meningiomas (IRS = 1-4) and to be consistently strong in WHO grade III meningiomas (IRS = 6-12), in WHO grade II meningiomas GLUT-1 expression was variable (IRS = 1-9). (2) Histologically typical, but brain invasive meningiomas (WHO grade II) showed no or similarly low levels of GLUT-1 expression as observed in WHO grade I meningiomas (IRS = 0-4). (3) GLUT-1 expression was observed in the form of a patchy, multifocal staining reaction in 76% of stained WHO grade I-III meningiomas, while diffuse staining (in 11%) and combined multifocal and areas of diffuse staining (in 13%) were only detected in WHO grades II and III meningiomas, except for uniform staining in angiomatous WHO grade I meningioma. (4) "Spontaneous" necrosis and small cell change typically occurred away from the intratumoral capillary

    The occurrence of a tumor at the colostomy site after abdominoperineal resection for rectal carcinoma is rare and it may be related to a previously resected carcinoma or another primary tumor. We report a 61-year-old man who developed an ulcerated skin nodule at her colostomy site 6 years after resection of a rectal adenocarcinoma. Histopathologically, the skin nodule was composed of atypical large and pleomorphic cells with high mitotic rate and they were arranged in nests and within lymphatic channels in the dermis. The neoplastic cells were immunoreactive for cytokeratin (CK) AE1/3, CK7, CK34ßE12, epithelial membrane antigen and vimentin while detection of human papillomavirus and Epstein-Barr virus DNA was negative. A diagnosis of basaloid large cell carcinoma of pulmonary origin was suggested and it was confirmed by computed tomography-guided fine needle aspiration of a right subpleural mass. A metastatic tumor at the colostomy site is an exceptional finding and may be the first manifestation of lung cancer, especially if it consist of pleomorphic large cells with high mitotic rate and basaloid immunophenotype.

    The major causes of central diabetes insipidus are neoplastic or infiltrative lesions of the hypothalamus or pituitary, severe head injuries and pituitary or hypothalamic surgery. Central diabetes insipidus caused by viral infections has been rarely reported in immunosuppressed patients, such as those with acquired immunodeficiency syndrome or Cushing's syndrome. We report the case of a 48-year-old woman suffering from diffuse large cell lymphoma, who developed hypotonic polyuria, hypernatriaemia and somnolence after the first course of chemotherapy with CHOEP and rituximab. Diabetes insipidus was diagnosed by low urine osmolarity and an undetectable vasopressin concentration. MRI revealed no pituitary abnormalities but encephalitis, and lumbar punction confirmed herpes zoster infection. To the best of our knowledge this is the first description of central diabetes insipidus in a lymphoma patient caused by an opportunistic CNS-infection.

    The scaling behavior for a binary fragmentation of critical percolation clusters is investigated by a large-cell Monte Carlo real-space renormalization group method in two and three dimensions. We obtain accurate values of critical exponents λ and phi describing the scaling of fragmentation rate and the distribution of fragments' masses produced by a binary fragmentation. Our results for λ and phi show that the fragmentation rate is proportional to the size of mother cluster, and the scaling relation σ = 1 + λ - phi conjectured by Edwards et al. to be valid for all dimensions is satisfied in two and three dimensions, where σ is the crossover exponent of the average cluster number in percolation theory, which excludes the other scaling relations.

    Large cell neuroendocrine carcinoma (LCNEC) is well-reported to result in unfavorable prognoses in many organ cancers while being rarely reported in gynecologic cancer, especially ovarian and endometrial cancers. Here we report a case of ovarian cancer with LCNEC which spread to distant organs within 1 year of primary surgery despite the fact that the post-surgical stage was Ia. The case received platinum-based chemotherapy as an adjuvant therapy after her curative surgery. However, LCNEC in the case was resistant to the chemotherapy. In our review of published works, ovarian cancer cases with LCNEC show poor prognoses regardless of adjuvant chemotherapy following complete resection. Median overall survival was 10 months in stage I cases. Development of chemotherapy sensitive for LCNEC is needed.

    To assess the prognostic significance of the immunophenotype in diffuse large cell lymphoma (DLCL), 105 DLCL patients were studied between 1978 and 1987 using a panel of 40 monoclonal antibodies applied to frozen tissue. Eighty-three patients were found to have B cell phenotypes, and 20 patients had T cell phenotypes. Focusing on markers relevant to clinical outcome among B cell LCL showed that lack of expression of the pan B antigens Leu14 and Leu16 were correlated with decreased survival (Leu14, P = 0.01; Leu16, P = 0.06; log-rank). HLA-DR activity also showed that lack of expression of this antigen correlated with poor survival (P = 0.004, log-rank). Kappa light chain immunoglobulin lack of expression showed predictive value for decreased survival as well (P = 0.005, log-rank). Multivariate analyses of known clinically important variables and the immune phenotypes confirm that the loss of HLA-DR and B cell aberrancy are independent factors predicting a poor clinical outcome. Losing some B activation/kappa antigens appears to be a broad biologic phenomenon linking surface antigen lack of expression with decreased survival. This suggests that aberrancy of immunophenotype and immunoglobulin status are key predictors of survival in B-LCL. PMID:3140668

    Patients with unresectable glioblastoma or anaplastic astrocytoma have a dismal prognosis. The role of neoadjuvant chemotherapy prior to irradiation in these patients has been studied primarily in non-randomized studies. We have compared the effect of neoadjuvant chemotherapy plus radiotherapy versus concomitant radiotherapy plus temozolomide in a retrospective analysis of two consecutive series of patients in whom surgery consisted of biopsy only. From 2003 to 2005, 23 patients received two cycles of temozolomide plus cisplatin followed by radiotherapy (Cohort 1), and from 2006 to 2010, 23 additional patients received concomitant radiotherapy and temozolomide followed by adjuvant temozolomide (Cohort 2). In Cohort 1, 91.3 % of patients received all planned chemotherapy cycles. Progression-free and overall survival were 3.3 and 8.5 months, respectively. In Cohort 2, progression-free and overall survival were 5.1 and 11.2 months, respectively. No differences between the two groups were observed in rate of completion of radiotherapy, progression-free or overall survival. MGMT methylation was assessed in 91.3 % of patients. In Cohort 1, patients without MGMT methylation showed a trend towards shorter progression-free survival (P = 0.09), while in Cohort 2, patients without MGMT methylation had longer progression-free survival (P = 0.04). In the overall patient population, neoadjuvant temozolomide plus cisplatin had neither a positive nor negative influence on outcome. However, our findings indicate that patients with methylated MGMT may derive greater benefit from neoadjuvant temozolomide than those with unmethylated MGMT.

  3. In contrast to agonist monoclonal antibodies, both C-terminal truncated form and full length form of Pleiotrophin failed to activate vertebrate ALK (anaplastic lymphoma kinase)?

    Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase essentially and transiently expressed during development in specific regions of the central and peripheral nervous system. ALK expression persists at a lower level in the adult brain. Thus, it might play an important role in both the normal development and function of the nervous system. The nature of the cognate ligand of this receptor in vertebrates is still a matter of debate. Pleiotrophin and midkine have been proposed as ligands of ALK but several independent studies do not confirm this hypothesis. Interestingly, a recent study proposed that a C-terminal truncated form of Pleiotrophin (Pleiotrophin.15) and not the full length form (Pleiotrophin.18) promotes glioblastoma proliferation in an ALK-dependent fashion. These data were obviously a strong basis to conciliate the conflicting results so far reported in the literature. In the present study, we first purified to homogeneity the two forms of Pleiotrophin secreted by HEK 293 cells. In contrast to agonist monoclonal antibodies, both Pleiotrophin.15 and Pleiotrophin.18 failed to activate ALK in neuroblastoma and glioblastoma cells expressing this receptor. Thus, for our point of view, ALK is still an orphan receptor in vertebrates.

    Anaplastic thyroid cancer (ATC) has a median survival less than 5 months and, to date, no effective therapy exists. Taxanes have recently been stated as the main drug treatment for ATC, and the histone deacetylase inhibitor valproic acid efficiently potentiates the effects of paclitaxel in vitro. Based on these data, this trial assessed the efficacy and safety of the combination of paclitaxel and valproic acid for the treatment of ATC. This was a randomized, controlled phase II/III trial, performed on 25 ATC patients across 5 centers in northwest Italy. The experimental arm received the combination of paclitaxel (80 mg/m2/weekly) and valproic acid (1,000 mg/day); the control arm received paclitaxel alone. Overall survival and disease progression, evaluated in terms of progression-free survival, were the primary outcomes. The secondary outcome was the pharmacokinetics of paclitaxel. The coadministration of valproic acid did not influence the pharmacokinetics of paclitaxel. Neither median survival nor median time to progression was statistically different in the two arms. Median survival of operated-on patients was significantly better than that of patients who were not operated on. The present trial demonstrates that the addition of valproic acid to paclitaxel has no effect on overall survival and disease progression of ATC patients. This trial is registered with EudraCT 2008-005221-11. PMID:27766105

    Anaplastic thyroid cancer (ATC) is among the most aggressive types of malignant cancer. Epidermal growth factor (EGF) plays a crucial role in the pathogenesis of ATC, and patients with thyroid carcinoma typically exhibit increased cysteine-rich protein 61 (Cyr61). In this study, we found that EGF treatment induced cell migration, stress fiber formation, Cyr61 mRNA and protein expressions, and Cyr61 protein secretion in ATC cells. The recombinant Cyr61 protein significantly induced cell migration; however, inhibition of Cyr61 activity by a Cyr61-specific antibody abrogated EGF-induced cell migration. EGF treatment also affected epithelial-to-mesenchymal transition (EMT)-related marker protein expression, as evidenced by an increase in vimentin and a decrease in E-cadherin expression. Inhibition of Cyr61 expression by Cyr61 siRNA decreased cell migration and reversed the EMT-related marker protein expression. EGF treatment increased the phosphorylation of the extracellular signal-regulated kinase (ERK) and cAMP response element-binding protein (CREB), and finally activated Cyr61 promoter plasmid activity. Our results suggest that Cyr61 is induced by EGF through the ERK/CREB signal pathway and that it plays a crucial role in the migration and invasion of ATC cells; moreover, Cyr61 might be a therapeutic target for metastatic ATC.

    Metastasis is the major cause of treatment failure in anaplastic thyroid carcinoma (ATC) patients. In the preliminary study, we demonstrated that interleukin (IL)-11 expression is positively correlated with distant metastasis in ATC. However, the mechanisms underlying remain largely unknown. Here, we found that cobalt chloride (a hypoxia mimetic) promoted IL-11 expression via HIF-1α activation. Furthermore, the resultant increase in IL-11 expression significantly induced epithelial-mesenchymal transition (EMT) in ATC cells, accompanied by Akt/GSK3β pathway activation and increased invasive and migratory abilities. Conversely, HIF-1α or IL-11 knockdown, or treating cells with a neutralizing antibody against IL-11, a PI3K inhibitor, or Akt inhibitor V, significantly suppressed the induction of EMT and counteracted the enhancements in invasive and migratory abilities. These results indicate that hypoxia increases IL-11 secretion in ATC cells via HIF-1α induction and that IL-11 then induces EMT in these cells via the PI3K/Akt/GSK3β pathway, ultimately improving their invasive and migratory potential. This study elucidates the prometastatic role played by IL-11 in ATC metastasis and indicates it as a potential target for the treatment of cancer metastasis. However, many questions remain to be explored. PMID:27487122

    It has been suggested that cancer stem cells (CSC) may play a central role in oncogenesis, especially in undifferentiated tumours. Anaplastic thyroid carcinoma (ATC) has characteristics suggestive of a tumour enriched in CSC. Previous studies suggested that the stem cell factor SOX2 has a preeminent hierarchical role in determining the characteristics of stem cells in SW1736 ATC cell line. In detail, silencing SOX2 in SW1736 is able to suppress the expression of the stem markers analysed, strongly sensitizing the line to treatment with chemotherapeutic agents. Therefore, in order to further investigate the role of SOX2 in ATC, a competing endogenous RNA (ceRNA) analysis was conducted in order to isolate new functional partners of SOX2. Among the interactors, of particular interest are genes involved in the biogenesis of miRNAs (DICER1, RNASEN, and EIF2C2), in the control cell cycle (TP53, CCND1), and in mitochondrial activity (COX8A). The data suggest that stemness, microRNA biogenesis and functions, p53 regulatory network, cyclin D1, and cell cycle control, together with mitochondrial activity, might be coregulated.

    Background Alectinib is an oral drug developed for the treatment of patients with fusion gene encoding echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK)-rearranged non-small cell lung cancer (NSCLC). Here, we present the case of a patient treated with alectinib who developed a hypersensitivity reaction with successful rechallenge treatment. Case Presentation A 39-year-old woman who was a passive smoker was referred to Osaka City University Hospital for the evaluation of a skin event caused by treatment for NSCLC with the fusion gene EML4-ALK. The skin reaction was observed on the anterior chest, upper arms, and ear auricles on day 11 of treatment with oral alectinib. The skin event presented as widely distributed erythematous macules that were confluent, indicating a severe and life-threatening form. The skin lesions started to resolve after the initiation of treatment with 40 mg prednisolone. After regrowth of the tumor, she received a rechallenge program for alectinib for 2 weeks; thereafter, alectinib treatment was successfully reinitiated. Conclusion To the best of our knowledge, we present the first case in which alectinib, which binds to the adenosine triphosphate site of EML4-ALK, induced erythema multiforme. Moreover, successful readministration of alectinib through our rechallenge program has not been reported so far. PMID:28101031

    Around 4% of advanced non-small-cell lung cancers (NSCLCs) have an ALK rearrangement at the time of diagnosis. This molecular feature is more frequent in young patients, with no/light smoking habit and with adenocarcinoma pathological subtype. Crizotinib is a tyrosine kinase inhibitor, targeting ALK, ROS1, RON, and MET. The preclinical efficacy results led to a fast-track clinical development. The US Food and Drug Administration (FDA) approval was achieved after the Phase I clinical trial in 2011 in ALK-rearranged advanced NSCLC progressing after a first-line treatment. In 2013, the randomized Phase III trial PROFILE-1007 confirmed the efficacy of crizotinib in ALK-rearranged NSCLC, compared to cytotoxic chemotherapy, in second-line setting or more. In 2014, the PROFILE-1014 trial showed the superiority of crizotinib in the first-line setting compared to the pemetrexed platinum doublet chemotherapy. The response rate was 74%, and the progression-free survival was 10.9 months with crizotinib. Based on these results, crizotinib received approval from the FDA and European Medicines Agency for first-line treatment of ALK-rearranged NSCLC. The various molecular mechanisms at the time of the progression (ALK mutations or amplification, ALK-independent mechanisms) encourage performing re-biopsy at the time of progression under crizotinib. The best treatment strategy at the progression (crizotinib continuation beyond progression, switch to second-generation tyrosine kinase inhibitors, or cytotoxic chemotherapy) depends on the phenotype of the progression, the molecular status, and the physical condition of the patient.

    Pim1, a serine/threonine kinase, is involved in several biological functions including cell survival, proliferation, and differentiation. While pim1 has been shown to be involved in several hematopoietic cancers, it was also recently identified as a target of aberrant somatic hypermutation in diffuse large cell lymphoma (DLCL), the most common form of non-Hodgkin's lymphoma. The crystal structures of Pim1 in apo form and bound with AMPPNP have been solved and several unique features of Pim1 were identified, including the presence of an extra {beta}-hairpin in the N-terminal lobe and an unusual conformation of the hinge connecting the two lobes of the enzyme. While the apo Pim1 structure is nearly identical with that reported recently, the structure of AMPPNP bound to Pim1 is significantly different. Pim1 is unique among protein kinases due to the presence of a proline residue at position 123 that precludes the formation of the canonical second hydrogen bond between the hinge backbone and the adenine moiety of ATP. One crystal structure reported here shows that changing P123 to methionine, a common residue that offers the backbone hydrogen bond to ATP, does not restore the ATP binding pocket of Pim1 to that of a typical kinase. These unique structural features in Pim1 result in novel binding modes of AMP and a known kinase inhibitor scaffold, as shown by co-crystallography. In addition, the kinase activities of five Pim1 mutants identified in DLCL patients have been determined. In each case, the observed effects on kinase activity are consistent with the predicted consequences of the mutation on the Pim1 structure. Finally, 70 co-crystal structures of low molecular mass, low-affinity compounds with Pim1 have been solved in order to identify novel chemical classes as potential Pim1 inhibitors. Based on the structural information, opportunities for optimization of one specific example are discussed.

    Context: Large cell calcifying Sertoli cell tumors (LCCSCT) present in isolation or, especially in children, in association with Carney Complex (CNC) or Peutz-Jeghers Syndrome (PJS). These tumors overexpress aromatase (CYP19A1), which leads to increased conversion of delta-4-androstenedione to estrone and testosterone to estradiol. Prepubertal boys may present with growth acceleration, advanced bone age, and gynecomastia. Objective: To investigate the outcomes of aromatase inhibitor therapy (AIT) in prepubertal boys with LCCSCTs. Design: Case series of a very rare tumor and chart review of cases treated at other institutions. Setting: Tertiary care and referral center. Patients: Six boys, five with PJS and one with CNC, were referred to the National Institutes of Health for treatment of LCCSCT. All patients had gynecomastia, testicular enlargement, and advanced bone ages, and were being treated by their referring physicians with AIT. Interventions: Patients were treated for a total of 6–60 months on AIT. Main Outcome Measures: Height, breast tissue mass, and testicular size were all followed; physical examination, scrotal ultrasounds, and bone ages were obtained, and hormonal concentrations and tumor markers were measured. Results: Tumor markers were negative. All patients had decreases in breast tissue while on therapy. Height percentiles declined, and predicted adult height moved closer to midparental height as bone age advancement slowed. Testicular enlargement stabilized until entry into central puberty. Only one patient required unilateral orchiectomy. Conclusions: Patients with LCCSCT benefit from AIT with reduction and/or elimination of gynecomastia and slowing of linear growth and bone age advancement. Further study of long-term outcomes and safety monitoring are needed but these preliminary data suggest that mammoplasty and/or orchiectomy may be foregone in light of the availability of medical therapy.

    SU6656 is a small-molecule indolinone that selectively inhibits Src family kinase and induces death of cancer cells. The aim of the present study was to investigate the influence of SU6656 on cell survival and to assess the role of p21 and PI3K/Akt signaling in cell survival resulting from SU6656 treatment in anaplastic thyroid carcinoma (ATC) cells. When 8505C, CAL62, and FRO ATC cells were treated with SU6656, the viability of 8505C and CAL62 ATC cells decreased only after treatment with SU6656 at a dosage of 100 μM for 72 h, while the viability of FRO ATC cells decreased after treatment with SU6656 in a concentration- and time-dependent manner. Cell viability was not changed by pretreatment with the broad-spectrum caspase inhibitor z-VAD-fmk. Phospho-Src protein levels were reduced, and p21 protein levels were elevated. Phospho-ERK1/2 protein levels were multiplied without alteration of total ERK1/2, total Akt, and phospho-Akt protein levels. Regarding FRO ATC cells, the decrement of cell viability, the increment of cleaved PARP-1 protein levels, and the decrement of phospho-Src protein levels were shown in p21 siRNA- or LY294002-pretreated cells compared to SU6656-treated control cells. ERK1/2 siRNA transfection did not affect cell viability and protein levels of cleaved PARP-1, p21, and Akt. In conclusion, these results suggest that SU6656 induces caspase-independent death of FRO ATC cells by overcoming the resistance mechanism involving p21 and Akt. Suppression of p21 and Akt enhances the cytotoxic effect of SU6656 in FRO ATC cells.

    Inflammatory myofibroblastic tumours (IMFT) may arise at any anatomical site, including lung, soft tissues, retroperitoneum and bladder. Although morphologically similar, these lesions encompass a spectrum of entities with differing aetiology, ranging from reactive/regenerative proliferations to low-grade neoplasms with a risk of local recurrence, but no significant metastatic potential. Vesical IMFT usually presents as a polypoid mass with a pale firm cut surface and can be of considerable size, mimicking a malignant tumour clinically and radiologically. Its good outcome, however, warrants conservative surgical excision, emphasising the importance of identification and distinction from malignant tumours of the bladder that may require more radical surgery and/or adjuvant therapy. We conducted a preliminary retrospective, comparative immunocytochemical study of 20 bladder tumours, including nine IMFTs, five spindle cell (sarcomatoid) carcinomas, two rhabdomyosarcomas, two leiomyosarcomas and two neurofibromas. The results confirmed IMFT positivity for smooth muscle actin, desmin and cytokeratin in 78-89% cases, resulting in potential confusion with sarcomatoid carcinoma or leiomyosarcoma. In contrast, cytoplasmic anaplastic lymphoma kinase (ALK 1) staining was present in eight IMFT (89%), but was not seen in any other lesion examined. The ALK 1 staining was confirmed by fluorescence in situ hybridisation, with translocation of the ALK gene present in 15-60% tumour cells in four of six IMFT examined, but not in four cases of sarcomatoid carcinoma or three of leiomyosarcoma. In conclusion, ALK 1 staining may be of value in the distinction of vesical IMFT from morphologically similar entities, and often reflects ALK gene translocations in these lesions.

    Purpose: Radiation Therapy Oncology Group 9402 compared procarbazine, lomustine, and vincristine (PCV) chemotherapy plus radiation therapy (PCV + RT) vs. RT alone for anaplastic oligodendroglioma. Here we report longitudinal changes in cognition and quality of life, effects of patient factors and treatments on cognition, quality of life and survival, and prognostic implications of cognition and quality of life. Methods and Materials: Cognition was assessed by Mini Mental Status Examination (MMSE) and quality of life by Brain-Quality of Life (B-QOL). Scores were analyzed for survivors and within 5 years of death. Shared parameter models evaluated MMSE/B-QOL with survival. Results: For survivors, MMSE and B-QOL scores were similar longitudinally and between treatments. For those who died, MMSE scores remained stable initially, whereas B-QOL slowly declined; both declined rapidly in the last year of life and similarly between arms. In the aggregate, scores decreased over time (p = 0.0413 for MMSE; p = 0.0016 for B-QOL) and were superior with age <50 years (p < 0.001 for MMSE; p = 0.0554 for B-QOL) and Karnofsky Performance Score (KPS) 80-100 (p < 0.001). Younger age and higher KPS were associated with longer survival. After adjusting for patient factors and drop-out, survival was longer after PCV + RT (HR = 0.66, 95% CI = 0.49-0.9, p = 0.0084; HR = 0.74, 95% CI = 0.54-1.01, p = 0.0592) in models with MMSE and B-QOL. In addition, there were no differences in MMSE and B-QOL scores between arms (p = 0.4752 and p = 0.2767, respectively); higher scores predicted longer survival. Conclusion: MMSE and B-QOL scores held steady in the upper range in both arms for survivors. Younger, fitter patients had better MMSE and B-QOL and longer survival.

    Background The aim of this study was to correlate histological features and molecular characteristics in anaplastic oligodendrogliomas (AOs). Methods The histological characteristics of 203 AO patients, enrolled in the French national network POLA, were analyzed. The genomic profiles of 191 cases were studied using genomic arrays. IDH mutational status was assessed by immunohistochemistry and direct sequencing. Results 1p/19q codeletion was present in 79% of cases and was associated with alpha-internexin expression (P < 10−4), IDH1/2 mutation (P < 10−4), chromosome 4 loss (P < 10−3), and better overall survival (P < 10−4). Based on mitotic index, microvascular proliferation (MVP), and necrosis, 3 groups of 1p/19q codeleted AOs were identified: (group 1) AO with more than 5 mitoses per 10-HPF, no MVP, and no necrosis; (group 2) AO with MVP and no necrosis; and (group 3) AO with MVP and necrosis. Compared with group 1, groups 2 and 3 AOs had a higher mean Ki-67 proliferation index and a higher rate of 9p and 9q losses. Compared with group 2, group 3 AOs had a higher number of chromosomal alterations including chromosome 4 loss. In the subgroup of 157 1p/19q codeleted AOs, chromosomal instability was associated with shorter progression-free survival (P = .024) and shorter overall survival (P = .023). Conclusions The present study shows that oligodendrogliomas with classic histological features remain a molecularly heterogeneous entity and should be stratified according to 1p/19q status because of its major prognostic relevance. Moreover, 1p/19q codeleted AOs are also heterogeneous. Interestingly, mitotic index, MVP, and necrosis help to classify them into 3 groups associated with distinct genomic alterations. PMID:24723566

    Purpose: To evaluate the correlation between the 1993 and 2000/2007 World Health Organization (WHO) classification with the outcome in patients with high-grade meningiomas. Patients and Methods: Between 1985 and 2004, 73 patients diagnosed with atypical or anaplastic meningiomas were treated with radiotherapy. Sections from the paraffin-embedded tumor material from 66 patients (90%) from 13 different pathology departments were re-evaluated according to the first revised WHO classification from 1993 and the revised classifications from 2000/2007. In 4 cases, the initial diagnosis meningioma was not reproducible (5%). Therefore, 62 patients with meningiomas were analyzed. Results: All 62 tumors were reclassified according to the 1993 and 2000/2007 WHO classification systems. Using the 1993 system, 7 patients were diagnosed with WHO grade I meningioma (11%), 23 with WHO grade II (37%), and 32 with WHO grade III meningioma (52%). After scoring using the 2000/2007 system, we found 17 WHO grade I meningiomas (27%), 32 WHO grade II meningiomas (52%), and 13 WHO grade III meningiomas (21%). According to the 1993 classification, the difference in overall survival was not statistically significant among the histologic subgroups (p = .96). Using the 2000/2007 WHO classifications, the difference in overall survival became significant (p = .02). Of the 62 reclassified patients 29 developed tumor progression (47%). No difference in progression-free survival was observed among the histologic subgroups (p = .44). After grading according to the 2000/2007 WHO classifications, significant differences in progression-free survival were observed among the three histologic groups (p = .005). Conclusion: The new 2000/2007 WHO classification for meningiomas showed an improved correlation between the histologic grade and outcome. This classification therefore provides a useful basis to determine the postoperative indication for radiotherapy. According to our results, a comparison of the

    Background Slug has been found to promote migration and invasion of many cancer cells, including anaplastic thyroid cancer (ATC). Thus, targeting Slug expression could provide new approaches for the treatment of patients with ATC. Material/Methods Small interfering RNA (siRNA) targeting Slug (Slug siRNA) was used to construct clonal derivatives in the metastatic ATC SW1736 cells. Slug cDNA transfection was used to restore the Slug expression in the Slug siRNA-transfected SW1736 cells (Slug siRNA/SW1736). E-cadherin siRNA was used to inhibit E-cadherin expression in the Slug siRNA/SW1736 cells. The SW1736 cell migration, invasion, and signaling pathway was analyzed in vitro. Furthermore, the stable Slug siRNA-transfected SW1736 clones were used for the lung metastasis assay in an in vivo mouse model. Results Targeting Slug expression in SW1736 cells showed a 45% decrease in migration and an 85% decrease in invasiveness in vitro. Knockdown of E-cadherin by E-cadherin siRNA transfection or Slug overexpression by Slug cDNA transfection restored the invasive and migrative ability in SW1736 cells. In addition, we found an 80% decrease in the number of macroscopic lung metastases nodes of mice by in vivo analysis. Western blot assay showed that Slug expression was inhibited and E-cadherin expression was increased in the Slug siRNA-transfected tumors. Conclusions Targeting Slug signaling pathway is effective in preventing lung metastasis in ATC. PMID:28070118

    We previously demonstrated the efficacy of gefitinib, a tyrosine kinase inhibitor of the epidermal growth factor receptor (EGFR), on an anaplastic thyroid cancer (ATC) cell line. We also observed that gefitinib was not effective in regulating cell growth in a different ATC cell line that exhibited an altered EGFR-initiated signal transduction pathway. In the present study, we attempted to regulate the downstream effector of EGFR-Akt-mammalian target of rapamycin (mTOR) pathway by an mTOR inhibitor, everolimus. A total of 8 ATC cell lines were employed, 7 of which were established in our institute. OCUT-2 was known to carry a mutation in the phosphoinositide-3-kinase, catalytic, α polypeptide gene (PI3KCA) and to be gefitinib-resistant, whereas ACT-1 exhibited a remarkable growth arrest by gefitinib. All the cell lines were tested for the cytotoxic effect of everolimus. The mechanisms of cellular toxicity were investigated by EGFR stimulation, cell cycle and concurrent exposure to paclitaxel. In OCUT-2, but not in any of the other cell lines, everolimus achieved a significant growth inhibition (inhibition of 30 and 50% was achieved by concentrations of 0.8 and 5 nM, respectively). The growth in OCUT-2 was inhibited by everolimus, even with concordant EGFR stimulation. This effect was demonstrated by a G2M cell cycle arrest. An additive effect of everolimus onto the cytotoxic effect of paclitaxel was demonstrated at a dose of 1–2 nM. A significant growth inhibitory effect of everolimus on the gefitinib-resistant ATC cell line was demonstrated, suggesting a possible correlation between the efficacy of everolimus and PI3KCA gene mutation and the significance of molecular-targeted therapy in the management of ATC.

    Anaplastic thyroid cancer (ATC) is the most aggressive form of human thyroid cancer, lacking any effective treatment. Sphingosine 1-phosphate (S1P) receptors and human ether-a'-go-go-related gene (HERG (KCNH2)) potassium channels are important modulators of cell migration. In this study, we have shown that the S1P(1-3) receptors are expressed in C643 and THJ-16T human ATC cell lines, both at mRNA and protein level. S1P inhibited migration of these cells and of follicular FTC-133 thyroid cancer cells. Using the S1P(1,3) inhibitor VPC-23019, the S1P(2) inhibitor JTE-013, and the S1P(2) receptor siRNA, we showed that the effect was mediated through S1P(2). Treatment of the cells with the Rho inhibitor C3 transferase abolished the effect of S1P on migration. S1P attenuated Rac activity, and inhibiting Rac decreased migration. Sphingosine kinase inhibitor enhanced basal migration of cells, and addition of exogenous S1P inhibited migration. C643 cells expressed a nonconducting HERG protein, and S1P decreased HERG protein expression. The HERG blocker E-4031 decreased migration. Interestingly, downregulating HERG protein with siRNA decreased the basal migration. In experiments using HEK cells overexpressing HERG, we showed that S1P decreased channel protein expression and current and that S1P attenuated migration of the cells. We conclude that S1P attenuates migration of C643 ATC cells by activating S1P(2) and the Rho pathway. The attenuated migration is also, in part, dependent on a S1P-induced decrease of HERG protein.

    The WHO 2007 classification of tumors of the CNS distinguishes between diffuse astrocytoma WHO grade II (A II(WHO2007)) and anaplastic astrocytoma WHO grade III (AA III(WHO2007)). Patients with A II(WHO2007) are significantly younger and survive significantly longer than those with AA III(WHO2007). So far, classification and grading relies on morphological grounds only and does not yet take into account IDH status, a molecular marker of prognostic relevance. We here demonstrate that WHO 2007 grading performs poorly in predicting prognosis when applied to astrocytoma carrying IDH mutations. Three independent series including a total of 1360 adult diffuse astrocytic gliomas with IDH mutation containing 683 A II(IDHmut), 562 AA III(IDHmut) and 115 GBM(IDHmut) have been examined for age distribution and survival. In all three series patients with A II(IDHmut )and AA III(IDHmut) were of identical age at presentation of disease (36-37 years) and the difference in survival between grades was much less (10.9 years for A II(IDHmut), 9.3 years for AA III(IDHmut)) than that reported for A II(WHO2007) versus AA III(WHO2007). Our analyses imply that the differences in age and survival between A II(WHO2007) and AA III(WHO2007) predominantly depend on the fraction of IDH-non-mutant astrocytomas in the cohort. This data poses a substantial challenge for the current practice of astrocytoma grading and risk stratification and is likely to have far-reaching consequences on the management of patients with IDH-mutant astrocytoma.

    Previously, we demonstrated that lovastatin, a HMG-CoA reductase inhibitor, induced apoptosis, differentiation, and inhibition of invasiveness of human anaplastic thyroid carcinoma cells (ATCs). Here, we further examined the effect of lovastatin on the growth of ARO cells. Lovastatin (0-20μM) concentration-dependently decreased cell number in cultured ATC and arrested the cell at the G0/G1 phase of the cell cycle. Western blot analysis revealed that lovastatin caused an increase of the protein level of p27 and cyclin-dependent kinase (CDK)4 and a decrease of the protein level of cyclin A2, cyclin D3, and phosphorylated Rb (pRb), but did not significantly change the protein levels of p21, cyclins D1 and E, and CDK2, in ARO cells. The formation of the CDK2-p27 complex was increased and the CDK2 activity was decreased in the lovastatin-treated ARO cells. Pretreatment of ARO cells with a p27, but not p21, antisense oligonucleotide prevented the lovastatin-induced G0/G1 arrest in ARO cells. The lovastatin-induced growth inhibition and translocation of RhoA and Rac1 in ARO cells were completely prevented by mevalonate and partially by geranylgeranyl pyrophosphate. Treatment of ARO cells with Y27632, an inhibitor of Rho-associated kinase, abolished the GGPP-mediated prevention of lovastatin-induced anti-proliferation and up-regulation and prolonged degradation of p27. Taken together, these data suggest that lovastatin treatment caused a reduction of Rho geranylgeranylation, which in turn increased the expression and stability of p27, and then inhibited ARO cell proliferation. These data suggest that lovastatin merits further investigation as multipotent therapy for treatment ATC.

    Expression of the small heat shock protein alphaB-crystallin in differentiated thyroid tumors has been described recently. In this study, we investigated the molecular mechanisms that affect the expression of alphaB-crystallin in benign goiters (n = 7) and highly malignant anaplastic thyroid carcinomas (ATCs) (n = 3). AlphaB-crystallin expression was compared with that of Hsp27-1. Immunoblot and quantitative real-time (RT) polymerase chain reaction revealed marked downregulation of alphaB-crystallin in all the tested ATCs and the ATC-derived cell line C-643 . In contrast, considerable expression of Hsp27-1 in benign and malignant thyroid tissue was demonstrated. Immunofluorescence analysis revealed no relevant topological differences between benign and malignant thyrocytes in the cytoplasmic staining of both proteins. Consistent and marked downregulation of TFCP2L1 was identified as one of the main mechanisms contributing to CRYAB gene silencing in ATCs. In addition, CRYAB gene promoter methylation seems to occur in distinct ATCs. In silico analysis revealed that the differential expression of alphaB-crystallin and Hsp27-1 results from differences between the alphaB-crystallin and Hsp27-1 promoter fragments (712 bp upstream from the transcriptional start site). Biological activity of the analyzed promoter element is confirmed by its heat shock inducibility. In conclusion, we demonstrate downregulation of alphaB-crystallin expression in highly dedifferentiated ATCs because of a tumor-specific transcription factor pattern. The differential expression of alphaB-crystallin and Hsp27-1 indicates functional differences between both proteins. PMID:16184762

    Anaplastic thyroid carcinoma (ATC) is one of the most aggressive human solid tumor and current treatments are ineffective in increasing patients' survival. Thus, the development of new therapeutic approaches for ATC is needed. We have previously shown that the oncolytic adenovirus dl922-947 induces ATC cell death in vitro and tumor regression in vivo. However, the impact of dl922-947 on the pro-tumorigenic ATC microenvironment is still unknown. Since viruses are able to regulate cytokine and chemokine production from infected cells, we sought to investigate whether dl922-947 virotherapy has such effect on ATC cells, thereby modulating ATC microenvironment. dl922-947 decreased IL-8/CXCL8 and MCP-1/CCL2 production by the ATC cell lines 8505-c and BHT101-5. These results correlated with dl922-947-mediated reduction of NF-κB p65 binding to IL8 promoter in 8505-c and BHT101-5 cells and CCL2 promoter in 8505-c cells. IL-8 stimulates cancer cell proliferation, survival and invasion, and also angiogenesis. dl922-947-mediated reduction of IL-8 impaired ATC cell motility in vitro and ATC-induced angiogenesis in vitro and in vivo. We also show that dl922-947-mediated reduction of the monocyte-attracting chemokine CCL2 decreased monocyte chemotaxis in vitro and tumor macrophage density in vivo. Interestingly, dl922-947 treatment induced the switch of tumor macrophages toward a pro-inflammatory M1 phenotype, likely by increasing the expression of the pro-inflammatory cytokine interferon-γ. Altogether, we demonstrate that dl922-947 treatment re-shape the pro-tumorigenic ATC microenvironment by modulating cancer-cell intrinsic factors and the immune response. An in-depth knowledge of dl922-947-mediated effects on ATC microenvironment may help to refine ATC virotherapy in the context of cancer immunotherapy. PMID:26625205

    The t(2;5) generates a chimeric NPM-ALK transcript encoded by the nucleophosmin NPM gene fused to the anaplastic lymphoma kinase gene ALK. Using a reverse transcriptase nested polymerase chain reaction assay we have detected NPM-ALK transcripts within CD30+ primary cutaneous lymphoma and lymphomatoid papulosis (LP). The t(2;5) was identified in 4 out of 9 CD30+ anaplastic lymphomas and in 1 out of 4 CD30+ pleomorphic lymphomas. Moreover, the t(2;5) was detected in 3 out of 10 LPs. All NPM-ALK-positive lymphomas and 1 NPM-ALK-positive LP exhibited a clonal rearrangement of the T cell receptor gamma-chain gene. The t(2;5) was detected in 2 cases of LP without other evidence for a clonal lymphoid population. To identify cells carrying the t(2;5) translocation, we used immunohistochemistry to detect the ALK-encoded p80 protein and in situ hybridization for the specific detection of NPM-ALK transcripts. Both p80 protein and NPM-ALK transcripts were expressed by anaplastic or large CD30+ lymphoma cells with positive NPM-ALK amplification. The presence of t(2;5) in a subset of CD30+ cutaneous lymphoma and LP may indicate a common pathogenesis with a subset of anaplastic nodal lymphoma. Images Figure 2 Figure 3 PMID:8701987

    INTRODUCTION Mixed large cell neuroendocrine neoplasms of the rectum are rare and aggressive neoplasms. Survival is poor due to the high rate of lymph node metastases and distant metastases at the time of diagnosis. PRESENTATION OF CASE We report a case of a 50-year-old male patient with a mixed large cell neuroendocrine carcinoma with squamous cell carcinoma of the rectum located 8 cm from the anal verge, treated with low anterior resection and total mesorectal excision with free surgical margins. There were lymph nodes metastases but no distant metastases at the time of diagnosis. The patient refused to receive adjuvant chemotherapy and died 6 months later due to liver failure as a result of multiple hepatic metastases. DISCUSSION There are not known predisposing factors for the development of neuroendocrine rectal carcinoma. A neuroendocrine carcinoma of the rectum is a rare tumor with an incidence of less than 0.1% of all colorectal malignancies. The median survival ranges from 5 to 10.4 months in several studies and there are not sufficient data in bibliography about ideal adjuvant therapy after resection of mixed squamous large cell neuroendocrine carcinoma of the rectum. CONCLUSION Low anterior resection and total mesorectal excision with free surgical margins in the presence of lymph nodes metastasis is not a sufficient treatment for rectal neuroendocrine carcinoma. More studies should be done in order to determine the ideal adjuvant treatment of these rare and aggressive tumors. PMID:24240071

    Determining histologic types of lung cancer on biopsies can be difficult. This study addresses the role of immunohistochemistry in histologic typing, using a tissue microarray (TMA) as "model biopsies," and presents a classification generated by an unsupervised hierarchical cluster analysis. A TMA was made from resection specimens of a consecutive series of 165 lung tumors. In a "tissue-spot review" with hematoxylin and eosin sections all the large cell carcinomas (N=22) were assigned to the noncommittal class of non-small cell lung cancer (NSCLC), as were an additional 37 tumors of defined histologic types. Adenocarcinomas and squamous cell carcinomas included with these NSCLC could be diagnosed by immunohistochemistry with antibodies against TTF-1, Napsin A, cytokeratin (CK)7, p40, p63, and CK5/6 with moderate to good sensitivities and specificities. Unsupervised hierarchical clustering was done with these data and additional high-molecular-weight cytokeratins, CD56, synaptophysin, and chromogranin immunohistochemistry. This delineated separate clusters for adenocarcinomas, large cell carcinomas, neuroendocrine tumors, and squamous cell carcinomas. Notably, adenocarcinoma and large cell carcinoma clusters were closely related and clearly set off from the squamous cell carcinoma cluster. As would be expected for a clinically well-staged series CDX2, GATA3, estrogen, and progesterone receptor immunohistochemistry remained negative in the vast majority of the tumors and, if positive, were restricted to very few cells. These results, the clustering data in particular, underpin the pragmatic recommendation canvassed with the IASLC/ATS/ERS classification of lung cancers that adenocarcinoma-type molecular studies should include NSCLC with a nonsquamous cell carcinoma immunophenotype.

    Large-cell neuroendocrine carcinoma (LCNEC) is a relatively uncommon variant of non-small cell lung cancer. Since the biological characteristics of LCNEC are similar to those of small cell lung cancer, LCNEC is usually treated with chemotherapy regimens used for small cell lung cancer. However, the outcomes are usually dismal. Here, we report a patient with LCNEC (a metastasis to the brain). After whole brain irradiation, he received a combination of amrubicin and irinotecan chemotherapy, and has been relapse-free for two years. This treatment regimen may be beneficial for patients with advanced LCNEC. PMID:19920936

    Bullous emphysema has been proven to be an important risk factor for lung cancer. Some reports have described pneumothorax caused by rupture of an emphysematous bulla, following which cancer is found in the resected specimen. A 72-year-old male patient was referred to our hospital because of dyspnea and high fever. Chest radiography and computed tomography (CT) revealed right pneumothorax and emphysematous bullae. There was also effusion in the bullae and thoracic cavity. Based on the diagnosis of pneumothorax and a lung infection associated with bullous emphysema, we resected the bullae. Pathological examination of the specimen revealed a mass and large cell carcinoma.

    Chromosomal translocations involving anaplastic lymphoma kinase (ALK) are the driving mutations for a range of cancers and ALK is thus considered an attractive therapeutic target. We synthesized a series of functionalized benzo[4,5]imidazo[1,2-c]pyrimidines and benzo[4,5]imidazo[1,2-a]pyrazines by an aza-Graebe-Ullman reaction, followed by palladium-catalyzed cross-coupling reactions. A sequential regioselective cross-coupling route is reported for the synthesis of unsymmetrically disubstituted benzo[4,5]imidazo[1,2-a]pyrazines. The inhibition of ALK was evaluated and compound 19 in particular showed good activity against both the wild type and crizotinib-resistant L1196M mutant in vitro and in ALK-transfected BaF3 cells.

    Background and Rationale: Anaplastic thyroid cancer (ATC) is characterized by pleomorphic cells, has a poor prognosis, is highly devastating disease, and is not curable. No reliable biomarkers of metastatic potential, helpful for early diagnosis of ATC and therapeutic response have been found yet. Thrombospondin-1 (TSP-1) plays a fundamental role in cancer progression by regulating cell stromal cross-talk in the tumor microenvironment. Goals: Our goal was to understand whether TSP-1 could affect protein levels of its integrin receptors (e.g., ITGα3, α6, and β1) and cell morphology in BRAFV600E-ATC cells in vitro and in vivo. Experimental Design: Anaplastic thyroid cancer-derived cell cultures and western blotting were used to assess integrin protein expression upon TSP-1 silencing. Immunohistochemistry was performed on orthotopic primary human ATC and metastatic ATC in lung tissue to compare TSP-1 and integrin protein expression levels. Results: TSP-1 knock-down down-regulates ITGα3, α6, and β1 in BRAFV600E-human ATC cells. BRAFV600E-ATC cells with TSP-1 knock-down were rounded compared to control cells, which displayed a spread morphology. TSP-1 knock-down also reduced TSP-1, ITGα3, α6, and β1 protein expression levels in vivo in the ATC microenvironment, which is enriched in stromal and inflammatory cells. Conclusion: TSP-1 silencing causes changes in ITG levels and ATC cell morphology. The assessment of TSP-1 and ITG levels might contribute to earlier metastatic potential of BRAFV600E-positive aggressive thyroid cancers, and allow improved patient selection for clinical trials.

    Suberoylanilide hydroxamic acid (SAHA), a potent pan-histone deacetylase (HDAC) inhibitor, has been clinically approved for the treatment of cutaneous T-cell lymphoma (CTCL). SAHA has also been shown to exert a variety of anticancer activities in many other types of tumors, however, few studies have been reported in large-cell lung carcinoma (LCC). Our study aimed to investigate the potential antitumor effects of SAHA on LCC cells. Here, we report that SAHA was able to inhibit the proliferation of the LCC cell line NCI-H460 in a dose- and time-dependent manner, induced cell apoptosis and G2/M cell cycle arrest, decreased AKT and ERK phosphorylation, inhibited the expression of pro-angiogenic factors (VEGF, HIF-1α) in vitro, and suppressed tumor progression in an NCI-H460 cell nude mouse xenograft model in vivo. These results indicate that SAHA can exert its strong antitumor effects in LCC patient.

    OBJECTIVE In 1999, the World Health Organization categorized large cell neuroendocrine carcinoma (LCNEC) of the lung as a variant of large cell carcinoma, and LCNEC now accounts for 3% of all lung cancers. Although LCNEC is categorized among the non-small cell lung cancers, its biological behavior has recently been suggested to be very similar to that of a small cell pulmonary malignancy. The clinical outcome for patients with LCNEC is generally poor, and the optimal treatment for this malignancy has not yet been established. Little information is available regarding management of LCNEC patients with brain metastases (METs). This study aimed to evaluate the efficacy of Gamma Knife radiosurgery (GKRS) for patients with brain METs from LCNEC. METHODS The Japanese Leksell Gamma Knife Society planned this retrospective study in which 21 Gamma Knife centers in Japan participated. Data from 101 patients were reviewed for this study. Most of the patients with LCNEC were men (80%), and the mean age was 67 years (range 39-84 years). Primary lung tumors were reported as well controlled in one-third of the patients. More than half of the patients had extracranial METs. Brain metastasis and lung cancer had been detected simultaneously in 25% of the patients. Before GKRS, brain METs had manifested with neurological symptoms in 37 patients. Additionally, prior to GKRS, resection was performed in 17 patients and radiation therapy in 10. A small cell lung carcinoma-based chemotherapy regimen was chosen for 48 patients. The median lesion number was 3 (range 1-33). The median cumulative tumor volume was 3.5 cm(3), and the median radiation dose was 20.0 Gy. For statistical analysis, the standard Kaplan-Meier method was used to determine post-GKRS survival. Competing risk analysis was applied to estimate GKRS cumulative incidences of maintenance of neurological function and death, local recurrence, appearance of new lesions, and complications.

    The efficacy of anaplastic lymphoma kinase (ALK) positive non-small-cell lung cancer (NSCLC) treatment with small molecule inhibitors is greatly challenged by acquired resistance. A recent study reported the newest generation inhibitor resistant mutation L1198F led to the resensitization to crizotinib, which is the first Food and Drug Administration (FDA) approved drug for the treatment of ALK-positive NSCLC. It is of great importance to understand how this extremely rare event occurred for the purpose of overcoming the acquired resistance of such inhibitors. In this study, we exploited molecular dynamics (MD) simulation to dissect the molecular mechanisms. Our MD results revealed that L1198F mutation of ALK resulted in the conformational change at the inhibitor site and altered the binding affinity of ALK to crizotinib and lorlatinib. L1198F mutation also affected the autoactivation of ALK as supported by the identification of His1124 and Tyr1278 as critical amino acids involved in ATP binding and phosphorylation. Our findings are valuable for designing more specific and potent inhibitors for the treatment of ALK-positive NSCLC and other types of cancer. PMID:28245558

    Activation of protooncogens and inactivation of putative tumor suppressor genes are genetic lesions considered to be important in lung carcinogenesis. Fifty-four cases of non-small-cell lung cancer (23 adenocarcinomas, 23 squamous-cell carcinomas, and 8 large-cell carcinomas) were examined for loss of DNA sequences at 13 polymorphic genetic loci. Loss of heterozygosity was seen more frequently in squamous-cell carcinoma than in adenocarcinoma. The loss of DNA sequences from the short arm of chromosome 17 (D17S1 locus) was detected in 8 of 9 heterozygous cases of squamous-cell carcinoma and in only 2 of 11 heterozygous cases of adenocarcinomas. Loss of DNA sequences from chromosome 3 was seen in 16 of 31 cases where the constitutive DNA was heterozygous-i.e., informative. Loss of heterozygosity at the chromosome 13q locus, D13S3, was seen in 9 of 21 informative cases, and in 2 cases, both adenocarcinomas, duplication of the intact DNA sequences suggested the possibility that mitotic recombination had occurred. Frequent DNA sequence deletions, including those from chromosome 17, in squamous-cell carcinomas may reflect the extensive mutagenic and clastogenic effects of tobacco smoke that may lead to inactivation of putative tumor-suppressor genes.

    The SDF-1/CXCR4 axis is associated with tumor progression and has been reported as a prognostic parameter, although with conflicting data for non-small cell lung cancer (NSCLC). This study examines a large cohort of clinically and pathologically well-characterized NSCLC patients and includes the activated form of CXCR4 (pCXCR4), which has not been studied in this context so far. SDF-1, CXCR4, and pCXCR4 were assessed immunohistochemically in 371 surgically resected NSCLC using a standardized tissue microarray platform. Extensive clinical and pathological data and a postoperative follow-up period of 17 years enabled detailed correlations. CXCR4 and pCXCR4 were frequently expressed on squamous cell carcinoma. Membranous expression of SDF-1 was a marker of poor prognosis and proved to be an independent prognostic parameter for the entire cohort and for patients with adenocarcinoma (ACA) and large cell carcinoma (LCC). Targeted cancer therapies blocking SDF-1/CXCR4 interaction already exist, and our data suggest that expression of SDF-1, especially on poorer prognosis subgroups of LCC and ACA, indicates patients that might benefit more than others. This should be taken into account when assessing the effectiveness of such targeted approaches for NSCLC patients and could lead to important implications.

    Paraneoplastic neurologic syndromes (PNS) can be the first manifestations of occult malignancies. If left untreated, PNS often lead to significant morbidity and mortality. Anti-Ri (anti-neuronal nuclear antibody type 2 [ANNA-2]) autoantibodies are commonly associated with breast and small cell lung cancers. Cases of anti-Ri paraneoplastic cerebellar degeneration are reported, but few describe severe nausea and coexisting limbic encephalitis as the major presenting features. We report a 75-year-old woman with medically-intractable emesis, encephalopathy, diplopia, vertigo, and gait ataxia for 3 months. Examination revealed rotary nystagmus, ocular skew deviation, limb dysmetria, and gait ataxia. After two courses of intravenous immunoglobulin, there was minimal improvement. Anti-Ri antibodies were positive in serum only. CT scan identified a 2.0 cm left lung mass, and histopathology revealed large cell neuroendocrine carcinoma with admixed adenocarcinoma non-small cell lung carcinoma (NCSLC). Though the patient achieved nearly complete clinical recovery after tumor resection, anti-Ri levels remained high at 20 months post-resection. To our knowledge this is the first report of a paraneoplastic brainstem cerebellar syndrome with coexisting limbic encephalitis involving anti-Ri positivity and associated mixed neuroendocrine/NSCLC of the lung with marked improvement after tumor resection.

    We have studied a translocation, t(9;14)(p13;q32), in a diffuse large-cell lymphoma cell line, KIS-1, that expresses the Ki-1 (CD30) antigen. Molecular cloning of the immunoglobulin heavy-chain locus (IGH) of this cell line revealed an unknown segment linked 5' to IGH. The breakpoint on chromosome 14 was 265 base pairs downstream from the 3' border of the JH6 joining gene segment. Class switch recombination deleted most of the constant genes of IGH (CH) and juxtaposed the C alpha 2 gene downstream of the translocation junction. Analysis of somatic cell hybrids and in situ chromosomal hybridization demonstrated that the translocated segment was normally located at band p13 of chromosome 9. The chromosome 9 sequences were transcriptionally active, giving rise to transcripts of approximately 11 kilobases. The KIS-1 cells seemed to have a small quantity of chimeric transcripts containing both chromosome 9 and C alpha 2 sequences. Images PMID:2153959

    Purpose Pulmonary large cell neuroendocrine carcinoma (LCNEC) is a highly aggressive neoplasm, whose biologic relationship to small cell lung carcinoma (SCLC) versus non-SCLC (NSCLC) remains unclear, contributing to uncertainty regarding optimal clinical management. To clarify these relationships, we analyzed genomic alterations in LCNEC compared with other major lung carcinoma types. Experimental Design LCNEC (n = 45) tumor/normal pairs underwent targeted next-generation sequencing of 241 cancer genes by Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets (MSK-IMPACT) platform and comprehensive histologic, immunohistochemical, and clinical analysis. Genomic data were compared with MSK-IMPACT analysis of other lung carcinoma histologies (n = 242). Results Commonly altered genes in LCNEC included TP53 (78%), RB1 (38%), STK11 (33%), KEAP1 (31%), and KRAS (22%). Genomic profiles segregated LCNEC into 2 major and 1 minor subsets: SCLC-like (n = 18), characterized by TP53+RB1 co-mutation/loss and other SCLC-type alterations, including MYCL amplification; NSCLC-like (n = 25), characterized by the lack of coaltered TP53+RB1 and nearly universal occurrence of NSCLC-type mutations (STK11, KRAS, and KEAP1); and carcinoid-like (n = 2), characterized by MEN1 mutations and low mutation burden. SCLC-like and NSCLC-like subsets revealed several clinicopathologic differences, including higher proliferative activity in SCLC-like tumors (P < 0.0001) and exclusive adenocarcinoma-type differentiation marker expression in NSCLC-like tumors (P = 0.005). While exhibiting predominant similarity with lung adenocarcinoma, NSCLC-like LCNEC harbored several distinctive genomic alterations, including more frequent mutations in NOTCH family genes (28%), implicated as key regulators of neuroendocrine differentiation. Conclusions LCNEC is a biologically heterogeneous group of tumors, comprising distinct subsets with genomic signatures of SCLC, NSCLC (predominantly

    . Gene profiling analysis shows that the expression of several genes is deregulated including PDGFRA (platelet-derived growth factor receptor) gene, encoding a receptor with tyrosine kinase activity. In angio-immunoblastic T-cell lymphomas molecular abnormalities are found in follicular helper T-cell (TFH) that express some distinctive markers such as CD10, PD-1, CXCR5 and the CXCL13 chemokine. ALK-positive anaplastic large cell lymphoma is a paradigme of T-cell lymphoma since it is associated with an X-ALK oncogenic fusion protein due to a translocation involving ALK gene at 2p23. ALK tyrosine kinase activates downstream pathways (Stat3/5b, Src kinases, PLCγ, PI3 kinase) implicated in lymphomagenesis, proliferation and protection against apoptosis. Specific ALK inhibitors are currently in clinical evaluation. Lastly several lymphomas are associated with infectious agents that play a direct (EB virus, HTLV1) or indirect role (e.g. Helicobacter pylori in MALT lymphoma) in lymphomagenesis.

    Objective To establish a real-time quantitative reverse transcription polymerase chain reaction assay (qRT-PCR) for the rapid, sensitive, and specific detection of echinoderm microtubule associated protein like 4-anaplastic lymphoma kinase (EML4-ALK) fusion genes in non-small cell lung cancer. Methods The specific primers for the four variants of EML4-ALK fusion genes (V1, V2, V3a, and V3b) and Taqman fluorescence probes for the detection of the target sequences were carefully designed by the Primer Premier 5.0 software. Then, using pseudovirus containing EML4-ALK fusion genes variants (V1, V2, V3a, and V3b) as the study objects, we further analyzed the lower limit, sensitivity, and specificity of this method. Finally, 50 clinical samples, including 3 ALK-fluorescence in situ hybridization (FISH) positive specimens, were collected and used to detect EML4-ALK fusion genes using this method. Results The lower limit of this method for the detection of EML4-ALK fusion genes was 10 copies/μl if no interference of background RNA existed. Regarding the method's sensitivity, the detection resolution was as high as 1% and 0.5% in the background of 500 and 5000 copies/μl wild-type ALK gene, respectively. Regarding the method's specificity, no non-specific amplification was found when it was used to detect EML4-ALK fusion genes in leukocyte and plasma RNA samples from healthy volunteers. Among the 50 clinical samples, 47 ALK-FISH negative samples were also negative. Among 3 ALK-FISH positive samples, 2 cases were detected positive using this method, but another was not detected because of the failure of RNA extraction. Conclusion The proposed qRT-PCR assay for the detection of EML4-ALK fusion genes is rapid, simple, sensitive, and specific, which is deserved to be validated and widely used in clinical settings.

    Adding temozolomide (TMZ) to radiation for patients with newly-diagnosed anaplastic astrocytomas (AAs) is common clinical practice despite the lack of prospective studies demonstrating a survival advantage. Two retrospective studies, each with methodologic limitations, provide conflicting advice regarding treatment. This single-institution retrospective study was conducted to determine survival trends in patients with AA. All patients ≥18 years with newly-diagnosed AA treated at Johns Hopkins from 1995 to 2012 were included. As we incorporated TMZ into high-grade glioma treatment regimens in 2004, patients were divided into pre-2004 and post-2004 groups for analysis. Clinical, radiographic, and pathologic data were collected. Median overall survival (OS) was calculated using Kaplan-Meier estimates. A total of 196 patients were identified; 74 pre-2004 and 122 post-2004; mean age 47 ± 15 years; 57 % male; 87 % white, 69 % surgical debulking. Mean RT dose 5676 + 746 cGy; duration of concurrent chemoradiation 5.8 ± 0.8 weeks; and mean adjuvant chemotherapy 4.3 + 2.8 cycles. Baseline prognostic factors did not differ between groups. Chemotherapy was administered to 12 % of patients pre-2004 (TMZ = 1, procarbazine, lomustine and vincristine = 2, carmustine wafer = 6) and 94 % post-2004 (TMZ in all, p < 0.001). Median OS was 32 months (95 % CI 23-43). Survival was longer in the post-2004 cohort (37 mo, 24-64) than pre-2004 (27 mo, 19-40; HR 0.75, 0.53-1.06, p = 0.11). Multivariate analysis controlling for age, Karnofsky performance status, and extent of resection revealed a 36 % reduced risk of death (HR 0.64, 0.44-0.91, p = 0.015) in patients treated post-2004. This retrospective review found survival in newly diagnosed patients with AA improved with the addition of temozolomide to standard radiation. Until prospective randomized phase III data are available, these data support the practice of incorporating TMZ in the management of

    Epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) fusion genes represent novel oncogenes that are associated with non–small-cell lung cancers (NSCLC). The feasibility of detecting EGFR mutations and ALK fusion genes in small biopsy specimens or surgical specimens was determined. Of the 721 NSCLC patients, a total of 305 cases were positive for EGFR mutations (42.3%). The rate of EGFR mutations in women was significantly higher than that in men. Histologically, the EGFR mutation rate in adenocarcinomas was significantly higher than that in squamous cell carcinomas. No difference in the EGFR mutation rate was observed between surgical specimens (42.1%) and small biopsy specimens (42.4%), which indicated that the EGFR mutation ratios in surgical specimens and small biopsy specimens were not different. In 385 NSCLC patients, 26 cases were positive for EML4-ALK (6.8%). However, 11.7% of the surgical specimens were EML4-ALK-positive, whereas the positive proportion in the small biopsy specimens was only 4.7%, which indicated that EML4-ALK-positive rate in the surgical specimens was significantly higher than that in the small biopsy specimens. Detection of EGFR gene mutations was feasible in small biopsy specimens, and screening for EML4-ALK expression in small biopsy specimens can be used to guide clinical treatments. PMID:27322143

    Alectinib is a second generation ALK inhibitor that has significant clinical activity in central nervous system (CNS) metastases in anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancer (NSCLC). Pseudoprogression (PsP) due to radiation necrosis during alecitnib treatment of central nervous system (CNS) metastases from ALK-rearranged NSCLC as been reported. Hence, distinguishing radiation-related PsP from alectinib-induced radiographic changes is important to avoid erroneous early trial discontinuation and abandonment of an effective treatment. However, it remains difficult to assess casuality of radiation necrosis is related to recent direct radiation or induced by alectinib treatment or both. It is also unknown how long from previous radiation can alectinib still induce radiation necrosis. Here we reported a crizotinib-refractory ALK-positive NSCLC patient who develop radiation necrosis in one of his metastatic CNS lesions after approximately 12 months of alectinib treatment who otherwise had on-going CNS response on alectinib. His most recent radiation to his CNS metastases was 7 years prior to the start of alectinib. This case illustrates that in the setting of pror CNS radiation, given the significant clinical activity of alectinib in CNS metastases in ALK-positive NSCLC patients the risk of CNS radiation necrosis remains long after previous radiation to the CNS metastases has been completed and can occur after durable response of treatment.

    Within 4 years of the discovery of anaplastic lymphoma kinase (ALK) rearrangements in non-small cell lung cancer (NSCLC), the ALK inhibitor crizotinib gained US and European approval for the treatment of advanced ALK-positive NSCLC. This was due to the striking response data observed with crizotinib in phase I and II trials in patients with ALK-positive NSCLC, as well as the favorable tolerability and safety profile observed. Recently published phase III data established crizotinib as a new standard of care for this NSCLC molecular subset. A consequence of such rapid approval, however, is the limited clinical experience and relative paucity of information concerning optimal therapy management. In this review, we discuss the development of crizotinib and the clinical relevance of its safety profile, examining crizotinib-associated adverse events in detail and making specific management recommendations. Crizotinib-associated adverse events were mostly mild to moderate in severity in clinical studies, and appropriate monitoring and supportive therapies are considered effective in avoiding the need for dose interruption or reduction in most cases. Therapy management of patients following disease progression on crizotinib is also discussed. Based on available clinical data, it is evident that patients may have prolonged benefit from crizotinib after Response Evaluation Criteria in Solid Tumors-defined disease progression, and crizotinib should be continued for as long as the patient derives benefit.

    Treatment outcomes of malignant lymphoma have improved due to the discovery of novel chemotherapeutic and molecular targeted agents as well as advances in their combination uses. However, the prognosis of T-cell lymphoma remains poorer than that of B-cell lymphomas, and progress is slow. The reasons include their chemotherapeutic resistant nature and the absence of effective antibody agents for T-cell lymphomas. The number of T-cell lymphoma subtypes increased from 21 in the WHO classification 2008 to 29 in the WHO classification 2016. This means that T-cell lymphomas are heterogeneous. T-cell lymphomas can be divided to ALK-positive anaplastic lymphoma (ALCL) with a good prognosis and others with poorer prognoses. ALK-positive ALCL can be successfully treated with CHOP, but the others cannot. P-glycoprotein resistant anthracyclines, etoposide, or hematopoietic stem cell transplantations are increasingly applied to improve outcomes, but no standard treatment approach has yet been established. Regarding relapsed/refractory T-cell lymphoma, many novel agents are currently under development. The treatment outcomes of T-cell lymphoma need to be improved by applying innovative strategies including further novel agents.

    Diffuse large-cell lymphoma (DLCL) is a neoplasm that is curable with chemotherapy in an appreciable percentage of patients. However, not all patients are cured and the best drug combination and optimal dose intensity have not yet been established. In an attempt to improve complete response rate and survival with minimal toxicity, we devised an alternating combination chemotherapy consisting of CHOP-Bleo (cyclophosphamide, doxorubicin, vincristine, prednisolone, and bleomycin) and POEM-Bleo (prednisolone, vincristine, etoposide, mitoxantrone, and bleomycin). Between March 1986 and October 1990, 30 newly-diagnosed patients with advanced DLCL were treated with the regimen. Of these 30 patients, 14 (47%) were 61 years of age or more, 15 (50%) had stage IV disease, 14 (47%) presented with constitutional symptoms, and 7 (23%) had T-cell lymphoma. After the completion of therapy, 23 (77%) achieved a complete response and 6 (20%) had a partial response. The actuarial relapse-free survival at 5 years is 52% and the overall survival projected to 5 years is 47%. Toxicity was generally mild and well tolerated. Although this alternating regimen had substantial activity as front-line chemotherapy for advanced DLCL, we conclude that the observed response rate and survival do not essentially differ from those achieved with conventional regimens and further clinical trials are thus not warranted.

    This paper provides a mini-review of evidence for negative turgor pressure in leaf cells starting with experimental evidence in the late 1950s and ending with biomechanical models published in 2014. In the present study, biomechanical models were used to predict how negative turgor pressure might be manifested in dead tissue, and experiments were conducted to test the predictions. The main findings were as follows: (i) Tissues killed by heating to 60 or 80 °C or by freezing in liquid nitrogen all became equally leaky to cell sap solutes and all seemed to pass freely through the cell walls. (ii) Once cell sap solutes could freely pass the cell walls, the shape of pressure-volume curves was dramatically altered between living and dead cells. (iii) Pressure-volume curves of dead tissue seem to measure negative turgor defined as negative when inside minus outside pressure is negative. (iv) Robinia pseudoacacia leaves with small palisade cells had more negative turgor than Metasequoia glyptostroboides with large cells. (v) The absolute difference in negative turgor between R. pseudoacacia and M. glyptostroboides approached as much as 1.0 MPa in some cases. The differences in the manifestation of negative turgor in living versus dead tissue are discussed.

    We report a case of age-related EBV-associated B-cell lymphoproliferative disorder (age-related EBV+ B-cell LPD) metachronously showing two distinct morphologic appearances: one of a polymorphic disease resembling classical Hodgkin lymphoma (CHL), and the other of a large-cell lymphoma. A 71-year-old man was admitted to the St. Marianna University Hospital because of fever and generalized lymphadenopathy. Right axillary lymph node biopsy revealed mixed cellularity classical Hodgkin lymphoma (MCHL). The patient was referred to the Tokyo Medical Center, where he was treated with chemotherapy and obtained CR. One year later, the patient again developed fever and generalized lymphadenopathy. Biopsy of the right cervical mass revealed a diagnosis of diffuse large B-cell lymphoma. The patient was treated with salvage chemotherapies and obtained the second CR. Two years later, the patient developed acute myeloid leukemia (AML). Although CR was achieved with chemotherapy, AML relapsed 5 months later and proved to be refractory. Two and a half years later, the patient developed right cervical lymph node enlargement. The biopsy again revealed diagnosis of MCHL. The patient died 2 months later. On reviewing all of the biopsy specimens, including the findings of immunohistochemistry and in situ hybridization, possibility of CHL was ruled out, because neoplastic giant cells resembling Hodgkin and Reed-Sternberg (HRS) cells were positive for both Oct2 and BOB.1, which has not been reported in CHL. Both HRS-like cells at the time of diagnosis of Hodgkin lymphoma and lymphoma cells at the time of diagnosis of non-Hodgkin lymphoma were positive for CD20 and EBV-encoded small RNAs. This case was finally diagnosed as having age-related EBV+ B-cell LPD. We report the case here as it underscores the difficulty in diagnosing age-related EBV+ B-cell LPDs and also suggests an important role of EBV in the pathogenesis of lymphoid neoplasms.

Results The ASCO panel concurred that the recommendations are clear, thorough, and based on the most relevant scientific evidence in this content area and present options that will be acceptable to patients. The CAP/IASLC/AMP guideline comprises 37 recommendations (evidence grade A or B), expert consensus opinions, or suggestions that address the following five principal questions: (1) When should molecular testing be performed? (2) How should EGFR testing be performed? (3) How should ALK testing be performed? (4) Should other genes be routinely tested in lung adenocarcinoma? (5) How should molecular testing be implemented and operationalized? Conclusion The ASCO review panel endorses the CAP/IASLC/AMP guideline. This guideline represents an important advance toward standardization of EGFR and ALK testing practices and is of major clinical relevance in advancing the care of patients with lung cancer. In the Discussion section, the ASCO review panel highlights three evolving areas: advances in ALK testing methodology, considerations for selecting appropriate populations for molecular testing, and emergence of other targetable molecular alterations.

    The CD30-targeted agent brentuximab vedotin has shown impressive activity in relapsed/refractory Hodgkin lymphoma and anaplastic large cell lymphoma in phase II studies. We have treated 24 patients with relapsed/refratory disease enrolled onto a Named Patient Programme during 2010-11 at a single UK center. Overall response rate across all histologies was 67% (Hodgkin 72%; anaplastic large cell 60%), complete response rate 25% (Hodgkin 17%; anaplastic large cell 60%), median progression-free survival 5.1 months, and toxicity mild to moderate in the majority of cases. Six patients proceeded to allogeneic transplantation and one patient awaits this procedure. These results are similar to phase II data and show that brentuximab vedotin provides a bridge to allogeneic transplantation in approximately one quarter of patients refractory to conventional salvage therapies. Best response was seen after four doses, so consideration of allogeneic transplantation should be made early and scheduled following the first assessment indicating response. PMID:23065511

    The diffuse aggressive large B-cell lymphomas are a heterogeneous group of B-cell malignancies. Although many are readily recognized due to characteristic clinical and pathologic features, several problematic areas still exist in diagnosis of these lymphomas due to a variety of reasons that include imprecise or difficult-to-apply diagnostic criteria, gaps in our understanding of lymphoma biology, and limitations in technologies available in the clinical laboratory compared to the research laboratory. This may result in some degree of confusion in the pathology report, particularly if the issues are not clearly explained, leading to frustration or misinterpretation on the part of the reader. In this review, I will discuss the pathologic features of a subset of the WHO 2008 classification diffuse aggressive large B-cell lymphomas, focusing on areas in which difficulties exist in diagnosis and/or biomarker marker assessment. A deeper understanding of the issues and areas of uncertainty due to limitations in our knowledge about the biology of these diseases should lead to better communication between pathologists and clinicians.

    The anaplastic lymphoma kinase (ALK) inhibitor alectinib is an effective treatment for ALK-positive non-small-cell lung cancer. This bioequivalence study evaluated the in vivo performance of test 3 formulations with the reduced wetting agent sodium lauryl sulfate (SLS) content. This randomized, 4-period, 4-sequence, crossover study compared alectinib (600 mg) as 25%, 12.5%, and 3% SLS hard capsule formulations with the reference 50% SLS clinical formulation in healthy subjects under fasted conditions (n = 49), and following a high-fat meal (n = 48). Geometric mean ratios and 90% confidence intervals (CIs) for Cmax , AUC0-last , and AUC0-∞ of alectinib, its major active metabolite, M4, and alectinib plus M4 were determined for the test formulations versus the reference formulation. Bioequivalence was concluded if the 90%CIs were within the 80% to 125% boundaries. The 25% SLS formulation demonstrated bioequivalence to the reference 50% SLS formulation for Cmax , AUC0-last , and AUC0-∞ of alectinib, M4, and alectinib plus M4 under both fasted and fed conditions. Further reductions in SLS content (12.5% and 3% SLS) did not meet the bioequivalence criteria. Cross-group comparisons showed an approximately 3-fold positive food effect. Reducing SLS to 25% resulted in a formulation that is bioequivalent to the current 50% SLS formulation used in alectinib pivotal trials.

    Inflammatory myofibroblastic tumors (IMT) in the head and neck region are rare neoplasms that generally mimic benign/low-grade neoplasms. Overexpression of anaplastic lymphoma kinase (ALK) has been reported in 50% of IMT cases, secondary to ALK activation by structural rearrangements in the ALK gene, which results in a fusion protein with echinoderm microtubule associated protein like 4 (EML4) in ~20% of cases. The present study describes a case of a 74-year-old woman with a malignant IMT in the right posterior hypopharynx harboring a previously unreported chromosomal rearrangement resulting in EML4 and ALK gene fusion. Strong ALK immunoreactivity was observed in neoplastic cells, while fluorescent in situ hybridization combined with fluorescent fragment analysis and direct sequencing identified the first case of the 3a/b variants of the EML4-ALK fusion gene in IMT. The results of the current study highlight the uncommon occurrence of ALK-positive IMT in the head/neck region and demonstrate the importance of integrating different molecular methodologies to identify unequivocal gene fusion characterization.

    Alectinib, an inhibitor of anaplastic lymphoma kinase (ALK), was approved by the Food and Drug Administration (FDA) for the treatment of patients with ALK-positive non-small cell lung cancer (NSCLC). Here we investigated the reversal effect of alectinib on multidrug resistance (MDR) induced by ATP-binding cassette (ABC) transporters, which is the primary cause of chemotherapy failure. We provide the first evidence that alectinib increases the sensitivity of ABCB1- and ABCG2-overexpressing cells to chemotherapeutic agents in vitro and in vivo. Mechanistically, alectinib increased the intracellular accumulation of ABCB1/ABCG2 substrates such as doxorubicin (DOX) and Rhodamine 123 (Rho 123) by inhibiting the efflux function of the transporters in ABCB1- or ABCG2-overexpressing cells but not in their parental sensitive cells. Furthermore, alectinib stimulated ATPase activity and competed with substrates of ABCB1 or ABCG2 and competed with [125I] iodoarylazidoprazosin (IAAP) photolabeling bound to ABCB1 or ABCG2 but neither altered the expression and localization of ABCB1 or ABCG2 nor the phosphorylation levels of AKT and ERK. Alectinib also enhanced the cytotoxicity of DOX and the intracellular accumulation of Rho 123 in ABCB1-overexpressing primary leukemia cells. These findings suggest that alectinib combined with traditional chemotherapy may be beneficial to patients with ABCB1- or ABCG2-mediated MDR. PMID:28303028

    Activating gene rearrangements of anaplastic lymphoma kinase (ALK) have been identified as driver mutations in non-small-cell lung cancer, inflammatory myofibroblastic tumors, and other cancers. Crizotinib, a dual MET/ALK inhibitor, has demonstrated promising clinical activity in patients with non-small-cell lung cancer and inflammatory myofibroblastic tumors harboring ALK translocations. Inhibitors of driver kinases often elicit kinase domain mutations that confer resistance, and such mutations have been successfully predicted using in vitro mutagenesis screens. Here, this approach was used to discover an extensive set of ALK mutations that can confer resistance to crizotinib. Mutations at 16 residues were identified, structurally clustered into five regions around the kinase active site, which conferred varying degrees of resistance. The screen successfully predicted the L1196M, C1156Y, and F1174L mutations, recently identified in crizotinib-resistant patients. In separate studies, we demonstrated that crizotinib has relatively modest potency in ALK-positive non-small-cell lung cancer cell lines. A more potent ALK inhibitor, TAE684, maintained substantial activity against mutations that conferred resistance to crizotinib. Our study identifies multiple novel mutations in ALK that may confer clinical resistance to crizotinib, suggests that crizotinib's narrow selectivity window may underlie its susceptibility to such resistance and demonstrates that a more potent ALK inhibitor may be effective at overcoming resistance.

  11. Severe Erosive Pill Esophagitis Induced by Crizotinib Therapy: A Case Report and Literature Review

    2016-01-01

    Previous case reports have described esophagitis thought to be secondary to crizotinib, an oral tyrosine-kinase inhibitor used in the treatment of anaplastic lymphoma kinase- (ALK-) positive non-small cell lung cancer (NSCLC). In those reports, the interval development of esophagitis was between two days and three months after initiating or reinitiating crizotinib therapy. We present a woman who developed ulcerative esophagitis ten months after beginning crizotinib therapy, which is highly unusual. We believe the provoking factor was a change in her medication administration routine, done to accommodate religious practices during the period of Ramadan. This case illustrates the mechanism of pill esophagitis and reinforces the importance of patient education when it comes to medication administration. Clinicians may consider early imaging or investigations in patients with concerning symptomatology in the context of crizotinib therapy or other offending medications. Future research may help to uncover additional risk factors for this exceedingly rare diagnosis in this patient population. Most importantly, this case highlights nonpharmacologic ways to improve tolerability and decrease adverse effects of a highly effective chemotherapeutic agent. PMID:28053793

    Background: Activated anaplastic lymphoma kinase (ALK) gene fusions are recurrent events in a small fraction of colorectal cancers (CRCs), although these events have not yet been exploited as in other malignancies. Methods: We detected ALK protein expression by immunohistochemistry and gene rearrangements by fluorescence in situ hybridisation in the ALKA-372-001 phase I study of the pan-Trk, ROS1, and ALK inhibitor entrectinib. One out of 487 CRCs showed ALK positivity with a peculiar pattern that prompted further characterisation by targeted sequencing using anchored multiplex PCR. Results: A novel ALK fusion with the carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase (CAD) gene (CAD-ALK fusion gene) was identified. It resulted from inversion within chromosome 2 and the fusion of exons 1–35 of CAD with exons 20–29 of ALK. After failure of previous standard therapies, treatment of this patient with the ALK inhibitor entrectinib resulted in a durable objective tumour response. Conclusions: We describe the novel CAD-ALK rearrangement as an oncogene and provide the first evidence of its drugability as a new molecular target in CRC. PMID:26633560

    Rearrangements of the anaplastic lymphoma kinase (ALK) have been described in multiple malignancies, including non-small cell lung cancer (NSCLC). ALK fusions have gain of function properties while activating mutations in wild-type ALK can also occur within the tyrosine kinase domain. ALK rearrangements define a new molecular subtype of NSCLC that is exquisitely sensitive to ALK inhibition. Crizotinib, an orally available small molecule ATP-mimetic compound which was originally designed as a MET inhibitor, was recognized to have "off-target" anti-ALK activity and has been approved in the USA for the treatment of patients with ALK-positive NSCLC. Chromosomal rearrangements involving the ROS1 receptor tyrosine kinase have also been recently described in NSCLC, while crizotinib is currently under clinical trial in this molecular subset of NSCLC patients. The basic approaches of any computer aided drug design work in terms of structure and ligand based drug design. Details of each of these approaches should be covered with an emphasis on utilizing both in order to develop multi-targeted small-molecule kinase inhibitors. Such multi-targeted tyrosine kinase inhibitors can have antiproliferative activity against both ROS1and ALK rearranged NSCLC. Herein, we highlight the importance of targeting these proteins and the advances in optimizing more potent and selective ALK and ROS1 kinase inhibitors.

    Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is one of the most common causes of hyponatremia. The usual causes are malignancies, central nervous system, pulmonary disorders, and drugs. Amiodarone is a broad spectrum antiarrhythmic agent widely used in the management of arrhythmias. The different side effects include thyroid dysfunction, visual disturbances, pulmonary infiltrates, ataxia, cardiac conduction abnormalities, drug interactions, corneal microdeposits, skin rashes, and gastrointestinal disturbances. SIADH is a rare but lethal side effect of amiodarone. We describe a 62-year-old male who was suffering from advanced prostatic malignancy, taking amiodarone for underlying heart disease. He developed SIADH which was initially thought to be paraneoplastic in etiology, but later histopathology refuted that. This case emphasizes the importance of detailed drug history and the role of immunohistochemistry in establishing the diagnosis and management of hyponatremia due to SIADH. PMID:24818037

    An adult Madagascar tree boa (Sanzinia madagascariensis) underwent coeliotomy for investigation of a coelomic mass. At surgery, a large mass originating from the peri-pancreatic adipose tissue and involving the gall bladder was removed. The snake did not recover from general anesthesia. A complete postmortem was performed, and samples were submitted to the University of Glasgow for histopathology. On histological examination, the mass was composed of adipose tissue infiltrated with a poorly demarcated spindle cell neoplasm. The neoplastic cells were highly pleomorphic with abundant cytoplasm and frequent clear cytoplasmic vacuoles, suggestive of adipocyte origin. Immunohistochemical characterization of the mass was inconclusive. Metastatic neoplastic cells were present within vessels in the liver, lungs, and brain. As an incidental finding, the gonads contained both maturing ovarian follicles and seminiferous tubules with intact germinal epithelium and evidence of spermatogenesis, along with other features of male and female gonad anatomy. The current report describes a rare neoplasm in snakes within an intersex Madagascar tree boa.

    This guideline provides recommendations for diagnostic and therapeutic procedures for patients with malignant gliomas. We differentiate evidence-based standards from reasonable options or non-evidence-based measures that should no longer be considered. The recommendations herein should provide a framework and assurance for the choice of diagnostic procedures and therapeutic measures and aim to reduce complications from unnecessary treatment and cost. The guideline contributes to a critical appreciation of concurrent drugs with a focus on the controlled use of anticonvulsants and steroids. It should serve as a guideline for all professionals involved in the diagnostics and care of glioma patients and also as a source of knowledge for insurance companies and other institutions involved in the cost regulation of cancer care in Europe. Implementation of the recommendations summarised here will need interdisciplinary structures of care for patients with brain tumours and structured processes of diagnostic and therapeutic procedures.

    Clinically apparent hypoglycemia is rare in adult horses. Hypoglycemia is a well-recognized paraneoplastic syndrome in humans and dogs with non-insulin-secreting tumors and may occur in horses as well. Hypoglycemia associated with non-insulin-secreting tumors is believed to result from production of an abnormal form of insulin-like growth factor II. Neoplasia should be considered in the differential diagnosis for adult horses with hypoglycemia.

    ABSTRACT We previously showed that cellular RedOx state governs the G1-S transition of AH130 hepatoma, a tumor spontaneously reprogrammed to the embryonic stem cell stage. This transition is impaired when the mithocondrial electron transport system is blocked by specific inhibitors (antimycin A) or the respiratory chain is saturated by adding to the cells high concentrations of pyruvate. The antimycin A or pyruvate block is removed by the addition of adequate concentrations of folate (F). This suggests that the G1-S transition of AH130 cells depends on a respiration-linked step of DNA synthesis related to folate metabolism. In the study reported here, we characterized the effects of methotrexate (MTX), an inhibitor of dihydofolate-reductase, on the G1-S transition of hepatoma cells, in the absence or the presence of exogenously added F, dihydrofolate (FH2) or tetrahydrofolate (FH4). MTX, at 1 μM or higher concentrations, inhibited G1-S transition. This inhibition was completely removed by exogenous folates. Surprisingly, 10 nM MTX stimulated G1-S transition. The addition of F, but not FH2 or FH4, significantly increased this effect. Furthermore, 10 nM MTX removed the block of the G1-S transition operated by antimycin A or pyruvate, an effect which was enhanced in the presence of F. Finally, the stimulatory effect of 10 nM MTX was inhibited in the presence of serine. Our findings indicated that, under certain conditions, MTX may stimulate, rather than inhibiting, the cycling of cancer cells exhibiting a stem cell-like phenotype, such as AH130 cells. This may impact the therapeutic use of MTX and of folates as supportive care. PMID:27841718

    Decreases in heart rate (HR) have been described in patients receiving crizotinib. We performed a large retrospective analysis of HR changes during crizotinib therapy. HRs from vital-sign data for patients with anaplastic lymphoma kinase (ALK)-positive nonsmall cell lung cancer enrolled in PROFILE 1005 and the crizotinib arm of PROFILE 1007 were analyzed. Sinus bradycardia (SB) was defined as HR <60 beats per minute (bpm). Magnitude and timing of HR changes were assessed. Potential risk factors for SB were investigated by logistic regression analysis. Progression-free survival (PFS) was evaluated according to HR decrease by <20 versus ≥ 20 bpm within the first 50 days of starting treatment. For the 1053 patients analyzed, the mean maximum postbaseline HR decrease was 25 bpm (standard deviation 15.8). Overall, 441 patients (41.9%) had at least one episode of postbaseline SB. The mean precrizotinib treatment HR was significantly lower among patients with versus without postbaseline SB (82.2 bpm vs. 92.6 bpm). The likelihood of experiencing SB was statistically significantly higher among patients with a precrizotinib treatment HR <70 bpm. PFS was comparable among patients with or without HR decrease of ≥ 20 bpm within the first 50 days of starting crizotinib. Decrease in HR is very common among patients on crizotinib. The likelihood of experiencing SB was statistically significantly higher among patients with a precrizotinib treatment HR <70 bpm. This is the first large-scale report investigating the association between treatment with a tyrosine kinase inhibitor and the development of bradycardia. HRs should be closely monitored during crizotinib treatment.

    Crizotinib, a first-generation anaplastic lymphoma kinase (ALK) tyrosine-kinase inhibitor, is known to be effective against echinoderm microtubule-associated protein-like 4 (EML4)-ALK-positive non-small cell lung cancers. Nonetheless, the tumors subsequently become resistant to crizotinib and recur in almost every case. The mechanism of the acquired resistance needs to be deciphered. In this study, we established crizotinib-resistant cells (A925LPE3-CR) via long-term administration of crizotinib to a mouse model of pleural carcinomatous effusions; this model involved implantation of the A925LPE3 cell line, which harbors the EML4-ALK gene rearrangement. The resistant cells did not have the secondary ALK mutations frequently occurring in crizotinib-resistant cells, and these cells were cross-resistant to alectinib and ceritinib as well. In cell clone #2, which is one of the clones of A925LPE3-CR, crizotinib sensitivity was restored via the inhibition of epidermal growth factor receptor (EGFR) by means of an EGFR tyrosine-kinase inhibitor (erlotinib) or an anti-EGFR antibody (cetuximab) in vitro and in the murine xenograft model. Cell clone #2 did not have an EGFR mutation, but the expression of amphiregulin (AREG), one of EGFR ligands, was significantly increased. A knockdown of AREG with small interfering RNAs restored the sensitivity to crizotinib. These data suggest that overexpression of EGFR ligands such as AREG can cause resistance to crizotinib, and that inhibition of EGFR signaling may be a promising strategy to overcome crizotinib resistance in EML4-ALK lung cancer.

    Identification of anaplastic lymphoma receptor tyrosine kinase (ALK) gene rearrangements is a standard diagnostic test in patients with advanced non-small cell lung cancer (NSCLC). The current study describes the experience of ALK rearrangement detection of a referral center in the public health care system of Galicia in North-Western Spain. The fluorescence in situ hybridization (FISH) patterns of the ALK gene and the clinical and pathological features of these patients are reported. This study is also of interest for comparative purposes due to the relative geographical isolation of the area, which could have contributed to particular genetic features. A total of 2,045 tissue samples from NSCLC patients were collected between October 2010 and July 2015 and tested for ALK rearrangements by FISH. Examination of 1,686 paraffin-embedded tissue specimens and 395 cytological samples (306 cell block preparations and 53 cytological smears) was conducted, and any associations between the FISH results and clinicopathological features were assessed. The rate of successful evaluation was marginally higher in tissue samples than in cytological samples (92.9% vs. 84.1%); this difference was not significant. ALK rearrangements were identified in 82 patients(4%): 65 (79.3%) in tissue specimens, 15 (18.3%) in cell block samples and 2 (2.4%) in cytological smears. This genetic translocation appeared to be associated with a non-smoking history, younger age, female gender, stage IV and adenocarcinoma histological type. The findings demonstrate that ALK evaluation by FISH is feasible in tissue and cytological samples. The clinical and pathological features of the ALK-positive series of patients are similar to those previously reported in the literature.

    A major challenge in cell biology is to understand how nanometer-sized molecules can organize micrometer-sized cells in space and time. One solution in many animal cells is a radial array of microtubules called an aster, which is nucleated by a central organizing center and spans the entire cytoplasm. Frog (here Xenopus laevis) embryos are more than 1 mm in diameter and divide with a defined geometry every 30 min. Like smaller cells, they are organized by asters, which grow, interact, and move to precisely position the cleavage planes. It has been unclear whether asters grow to fill the enormous egg by the same mechanism used in smaller somatic cells, or whether special mechanisms are required. We addressed this question by imaging growing asters in a cell-free system derived from eggs, where asters grew to hundreds of microns in diameter. By tracking marks on the lattice, we found that microtubules could slide outward, but this was not essential for rapid aster growth. Polymer treadmilling did not occur. By measuring the number and positions of microtubule ends over time, we found that most microtubules were nucleated away from the centrosome and that interphase egg cytoplasm supported spontaneous nucleation after a time lag. We propose that aster growth is initiated by centrosomes but that asters grow by propagating a wave of microtubule nucleation stimulated by the presence of preexisting microtubules.

    The anaplastic lymphoma kinase (ALK) gene plays an important physiologic role in the development of the brain and can be oncogenically altered in several malignancies, including non-small-cell lung cancer (NSCLC) and anaplastic large cell lymphomas (ALCL). Most prevalent ALK alterations are chromosomal rearrangements resulting in fusion genes, as seen in ALCL and NSCLC. In other tumors, ALK copy-number gains and activating ALK mutations have been described. Dramatic and often prolonged responses are seen in patients with ALK alterations when treated with ALK inhibitors. Three of these—crizotinib, ceritinib, and alectinib—are now FDA approved for the treatment of metastatic NSCLC positive for ALK fusions. However, the emergence of resistance is universal. Newer ALK inhibitors and other targeting strategies are being developed to counteract the newly emergent mechanism(s) of ALK inhibitor resistance. This review outlines the recent developments in our understanding and treatment of tumors with ALK alterations. PMID:28050598

    A 41-year-old man was referred to our hospital for treatment of anaplastic lymphoma kinase (ALK)-negative anaplastic large cell lymphoma. Chronic active Epstein-Barr virus (CAEBV) was diagnosed based on the findings of elevated EBV antibody titers and positive EBV-DNA in the peripheral blood, and cord blood stem cell transplantation (CBT) was performed. The EBV-DNA levels in the blood fell below the limit of detection. His lymphoma relapsed on Day 165 with the appearance of eruptions, which disappeared after the withdrawal of tacrolimus. One year after transplantation, there were no signs of recurrence. This encouraging result suggests that CBT should be considered for adult cases of CAEBV with aggressive clinical manifestations.

    T-cell lymphomas are rare and aggressive malignancies associated with poor outcome, often because of the development of resistance in the lymphoma against chemotherapy as well as intolerance in patients to the established and toxic chemotherapy regimens. In this review article, we discuss the epidemiology, pathophysiology, current standard of care, and future treatments of common types of T-cell lymphomas, including adult T-cell leukemia/lymphoma, angioimmunoblastic T-cell lymphoma, anaplastic large-cell lymphoma, aggressive NK/T-cell lymphoma, and cutaneous T-cell lymphoma.

    The spectrum of CD30+ lymphoproliferative diseases of the skin includes CD30+ cutaneous anaplastic large cell lymphoma, lymphomatoidpapulosis, as well as borderline cases. These entities constitute the second most common group of cutaneous lymphomas according to the newly revised World Health Organization and European Organisation for Research and Treatment of Cancer consensus classification. Recent progress in immune and molecular biology, and identification of therapeutic targets have increased our understanding of these diseases and have led to novel treatment approaches. This review will provide an update on recent findings of immunologic, molecular, cytogenetic features and treatment strategies for patients with CD30+ lymphoproliferative diseases.

    Advanced grades of glioblastoma are highly aggressive, especially in terms of multisite spread within the brain or even to distant sites at the spinal cord. In advanced grades of glioblastoma, glutamate and glutamine are reported to be increased in concentration in the extracellular fluid. It has been reported that glutamate acts as an extracellular signaling molecule for facilitating local spread of advanced grades of glioblastoma. In the present study, we aimed to examine whether glutamate uptake mechanisms is impaired in advanced glioblastoma. The possible downregulated mechanisms of glutamate uptake would facilitate persistence of glutamate in the extracellular environment, rather than intracellular uptake. We obtained biobanked human specimens of glioblastoma and tested expression of proteins belonging to the solute carrier families of proteins that are known to function as membrane-located excitatory amino acid like glutamate transporters. The present study provides preliminary evidence of the downregulation of membrane expression of excitatory amino acid transporters solute carrier family 1 member 3 (SLC1A3) and its palmitoylated form in gliosomes, as well as SLC1A2 in the glio-synaptosomes. Compounds like riluzole used in the treatment of amyotrophic lateral sclerosis and the antibiotic ceftriaxone have the potential to facilitate glutamate uptake. These medications may be examined as adjunct chemotherapy in the massively aggressive tumor glioblastoma multiforme.

    A series of new 2,4-diarylaminopyrimidine analogues (DAAPalogues) was developed by incorporation of a substituted 2-aminothiazole component as the C-2 substituent of the center pyrimidine core. Compound 5i showed highest potency of 12.4 nM against ALK and 24.1 nM against ALK gatekeeper mutation L1196M. Although only having moderate cellular potency in the SUP-M2 cells harboring NPM-ALK, compound 5i showed good kinase selectivity and dose-dependently inhibited phosphorylation of ALK and its down-stream signaling pathways.

    Recent studies have suggested a potential prognostic role of alterations of the fragile histidine triad (FHIT) gene in diffuse large B-cell lymphoma. To evaluate possible mechanisms of FHIT inactivation and to further clarify its potential prognostic relevance, we analyzed a set of 114 diffuse large B-cell lymphoma with clinical follow-up information. Tissue microarrays were analyzed by immunohistochemistry for protein expression, and corresponding DNA samples were analyzed for FHIT promotor hypermethlyation. Reduced or absent FHIT expression was found in 75 of 114 diffuse large B-cell lymphoma (66%), but was unrelated to clinical tumor stage or patient prognosis. FHIT promotor hypermethylation was observed in 29 of 93 (23%) interpretable diffuse large B-cell lymphoma. Hypermethylation was not significantly correlated to protein expression loss, which could be explained by competing mechanisms for FHIT inactivation in a substantial fraction of non FHIT hypermethylated diffuse large B-cell lymphoma. Hypermethylation was significantly associated with poor prognosis of diffuse large B-cell lymphoma patients and predominantly seen in nongerminal center diffuse large B-cell lymphoma (27%), but less frequent (13%) in germinal center diffuse large B-cell lymphoma. In summary, these data suggest that promotor hypermethylation is responsible for reduced FHIT expression in a substantial subset of diffuse large B-cell lymphoma, which is primarily composed of nongerminal center subtype with poor patient prognosis.

  1. Cytoplasmic reorganization accompanies the deposition of a bipolar cell wall in the large-celled red alga Anotrichium tenue.

    PubMed

    Sylvester, A W; Waaland, J R

    1992-01-01

    The filamentous red alga Anotrichium tenue C. Aghard (Naegeli) (formerly Griffithsia tenuis C. Aghard; Baldock, 1976, Aust. T. Bot. 24, 509-593) has large (1-2 mm long), cylindrical, multinucleate cells that exhibit a daily, cyclic redistribution of chloroplasts. Chloroplasts accumulate in the mid-region of each growing cell during the day; consequently, filaments appear banded with a light apical end-band, a dark mid-band and a light basal end-band in each growing cell. Chloroplasts disperse at night so that the bands are no longer visible and the cells appear evenly pigmented. Anotrichium tenue also has a type of cell elongation, known as bipolar band growth, in which new material is added to the microfibrillar part of the wall in bands located at the apical and basal poles of elongating cells. This site of wall growth corresponds to the position of the light-colored end-bands present during the day. Here we examine the structural relationship between the cytoplasmic bands and the wall-growth bands. Our results show that, in addition to the previously described bipolar wall bands, there is a non-microfibrillar wall band in the mid-region of the cell. This wall component apparently branches from near the top of the microfibrillar outer wall and terminates near but not at the bottom of the cell. It contains nodules of sulphated polysaccharide material secreted from a band of vesicles, which co-localize with the chloroplasts in the mid-band. The outer wall appears to enclose the entire cell. Nuclei do not redistribute with the chloroplasts or wall vesicles into the mid-band but remain evenly distributed throughout the cytoplasm. Each wall component grows by a different mechanism. We show that two types of wall growth, diffuse and the bipolar-type of tip growth, occur in the same cell and we propose that the observed segregation of the cytoplasm supports localized growth of the unique inner wall component. Additionally, we show that A. tenue is an excellent model for study of the role and mechanism of cytoplasmic compartmentalization and cell polarity during plant cell growth.

    The authors report the case of a 69-year-old man with chronic obstructive pulmonary disease and previous pulmonary tuberculosis, who presented to the emergency department with abdominal and low back pain, anorexia and weight loss, rapidly evolving into shock. An initial CT scan revealed pulmonary condensation with associated cavitation and an iliopsoas mass suggestive of a psoas abscess. He was admitted in an intensive care unit unit; after a careful examination and laboratory assessment, the aetiology was yet undisclosed. MRI showed multiple retroperitoneal lymphadenopathies, bulky nodular adrenal lesions and bilateral iliac lytic lesions. Hypocortisolism was detected and treated with steroids. A CT-guided biopsy to the psoas mass and lytic lesions identified infiltration of non-small lung carcinoma. The patient died within days. Psoas metastases and adrenal insufficiency as initial manifestations of malignancy are rare and can be misdiagnosed, particularly in the absence of a known primary tumour.

  3. Recurrent autoimmune inner ear disease (AIED) and polyarteritis nodosa in a patient with large cell lung carcinoma.

    2007-06-01

    Autoimmune inner ear disease (AIED) is a very rare disorder with distinct clinical features and can occur in patients with malignancy or autoimmune diseases. We report a 72-year-old male patient with polyarteritis nodosa treated continuously for 5 years with aggressive immunosuppressive drugs, including cyclophosphamide, who experienced three episodes of acute hearing loss during treatment. Organic lesions of the external and middle ear were excluded by repeated examinations, and if one subscribes to McCabe's (Ann Otol Rhinol Laryngol 88:585-589, 1979) definition of AIED, this condition must be considered as the likely cause of the hearing loss. During the period of treatment, three episodes of AIED occurred, and eventually, lung cancer developed. From the time relationship and clinical manifestations of neuropathy and livedo reticularis, the first episode of hearing loss was more likely to be related to vasculitis itself, while the third episode may well have been associated with the development of lung cancer given the dramatic improvement in the clinical condition following treatment of the tumor by excision and cancer chemotherapy. Coexistence of AIED, vasculitis, and malignancy in the same patient has only been reported infrequently, and our case suggests that this coexistence may not be coincidental. For those patients with autoimmune disease who are on long-term immunosuppressive drug therapy, active surveillance for a nascent malignant tumor should be exercised if AIED recurs or persists.

    CD30, a member of the tumor necrosis factor receptor superfamily, is a transmembrane glycoprotein receptor consisting of an extracellular domain, a transmembrane domain, and an intracellular domain. CD30 has emerged as an important molecule in the field of targeted therapy because its expression is generally restricted to specific disease types and states. The major cancers with elevated CD30 expression include Hodgkin lymphoma and anaplastic large T-cell lymphoma, and CD30 expression is considered essential to the differential diagnosis of these malignancies. Most commonly, CD30 expression is detected and performed by immunohistochemical staining of biopsy samples. Alternatively, flow cytometry analysis has also been developed for fresh tissue and cell aspiration specimens, including peripheral blood and bone marrow aspirate. Over the past several years, several therapeutic agents were developed to target CD30, with varying success in clinical trials. A major advance in the targeting of CD30 was seen with the development of the antibody-drug conjugate brentuximab vedotin, which consists of the naked anti-CD30 antibody SGN-30 conjugated to the synthetic antitubulin agent monomethyl auristatin E. In 2011, brentuximab vedotin was approved by the US Food and Drug Administration for use in Hodgkin lymphoma and anaplastic large cell lymphoma based on clinical trial data showing high response rates in these indications. Ongoing trials are examining brentuximab vedotin after autologous stem cell transplantation, as part of chemotherapy combination regimens, and in other CD30-expressing malignancies, including primary mediastinal large B-cell lymphomas, diffuse large B-cell lymphoma, lymphoma positive for Epstein-Barr virus, peripheral T-cell lymphoma not otherwise specified, and cutaneous anaplastic large cell lymphoma.

    Breast involvement by non-Hodgkin lymphomas is rare, and exceptional for T-cell lymphomas; we studied the morphologic, immunophenotypic, and clinical features of 11 patients with T-cell non-Hodgkin lymphomas involving the breast. Four cases fulfilled the definition criteria for primary breast lymphomas, 3 females and 1 male, with a median age of 51 years. One primary breast lymphomas was T-cell lymphoma unspecified, other was subcutaneous panniculitis-like T-cell lymphoma, and 2 cases were anaplastic large cell lymphomas. One of the anaplastic large cell lymphoma cases was found surrounding a silicone breast implant and presented as clinically as mastitis; whereas the other case occurred in a man. T-cell lymphoma secondarily involved the breast in 7 patients, all women and 1 bilateral, with a median age of 29 years. These secondary breast lymphomas occurred as part of widespread nodal or leukemic disease. Three patients had adult T-cell leukemia/lymphoma, including the patient with bilateral lesions, 3 others had precursor T-lymphoblastic lymphoma/leukemia, and the other presented with a peripheral-T-cell lymphoma nonotherwise specified type. Breast T-cell lymphomas are very infrequent and are morphologically and clinically heterogeneous. PMID:19318917

    Both B and T lymphocytes have signature traits that set them apart from other cell types. They actively and repeatedly rearrange their DNA in order to produce a unique and functional antigen receptor, they have potential for massive clonal expansion upon encountering antigen via this receptor or its precursor, and they have the capacity to be extremely long lived as ‘memory’ cells. All three of these traits are fundamental to their ability to function as the adaptive immune response to infectious agents, but concurrently render these cells vulnerable to transformation. Thus, it is classically considered that lymphomas arise at a relatively late stage in a lymphocyte's development during the process of modifying diversity within antigen receptors, and when the cell is capable of responding to stimulus via its receptor. Attempts to understand the aetiology of lymphoma have reinforced this notion, as the most notable advances to date have shown chronic stimulation of the antigen receptor by infectious agents or self-antigens to be key drivers of these diseases. Despite this, there is still uncertainty about the cell of origin in some lymphomas, and increasing evidence that a subset arises in a more immature cell. Specifically, a recent study indicates that T-cell lymphoma, in particular nucleophosmin-anaplastic lymphoma kinase-driven anaplastic large cell lymphoma, may originate in T-cell progenitors in the thymus.

    The interleukin (IL)–22R1 chain of the heterodimeric IL-22 receptor is not expressed on normal leukocytes, but this receptor is expressed on T cells from anaplastic lymphoma kinase–positive (ALK+) anaplastic large cell lymphoma (ALCL) patients. To investigate the consequences of aberrant expression of this receptor on lymphocytes, we generated transgenic mice that express IL-22R1 on lymphocytes. The health of these animals progressively deteriorated at 8 to 12 weeks of age, as they displayed respiratory distress, rough coat and sluggish movement, and subsequent lethality due to multiorgan inflammation. The IL-22R1 transgenic animals developed neutrophilia that correlated with increased levels of circulating IL-17 and granulocyte colony-stimulating factor. In addition, these mice had increased serum IL-22 levels, suggesting that T cells expressing IL-22R1 generate IL-22 in a positive autoregulatory loop. As a result of the mouse model findings, we analyzed circulating cytokine levels in ALK+ALCL patients and detected elevated levels of IL-22, IL-17, and IL-8 in untreated patient samples. Importantly, IL-22 and IL-17 were undetectable in all patients who were in complete remission after chemotherapy. This study documents a previously unknown role of IL-22R1 in inflammation and identifies the involvement of IL-22R1/IL-22 in ALK+ALCL. PMID:20971950

    Astroblastomas are rare, potentially curable primary brain tumors which can be difficult to diagnose. We present the case of astroblastoma in a 73-year-old male, an atypical age for this tumor, more classically found in pediatric and young adult populations. Through our case and review of the literature, we note that this tumor is frequently reported in adult populations and the presentation of this tumor in the elderly is well described. This tumor is an important consideration in the differential diagnosis when managing both pediatric and adult patients of any age who present with the imaging findings characteristic of this rare tumor.

    Binding of the recently introduced anti-cancer drug, crizotinib (CRB) with the bovine serum albumin (BSA) was comprehensively studied with the aid of fluorescence and UV-Vis spectroscopic as well as molecular docking techniques. The collective results of the study under the simulated physiological conditions proposed a static type of binding occurring between the CRB and BSA with binding constants of 104 L mol- 1. BSA conformational changes were investigated using three dimensional (3D) and synchronous fluorescence measurements. Moreover, the results of site marker competitive experiments and molecular docking, it could be deduced that CRB was inserted into the subdomain IIA (site I) of BSA yielding a more stabilized system. This was further confirmed with the molecular docking results which revealed that CRB is located in the active site residues Try149, Glu152, Ser191, Arg194, Arg198, Trp213, Arg217, Arg256, His287, Ala290, Glu291, Ser343, Asp450 within a radius of 6 Å. Combining the molecular docking studies and the computed thermodynamic parameters, it can be inferred that hydrophobic and electrostatic interactions are the major binding forces involved in formation of the CRB-BSA complex.

    Analyzing EGFR mutations and detecting ALK gene fusion are indispensable when planning to treat pulmonary adenocarcinoma. Malignant pleural effusion (MPE) is a devastating complication of lung cancer and sometimes the only source for mutation analysis. The percentage of tumor cells in the pleural effusion may be low; therefore, mutant enrichment is required for a successful analysis. The EGFR mutation status in MPE was determined using three methods: (1) PCR sequencing of genomic DNA (direct sequencing), (2) mutant-enriched PCR sequencing of genomic DNA using peptide nucleic acid (PNA-sequencing), and (3) PCR sequencing of cDNA after reverse transcription for cellular RNA (RNA-sequencing). RT-PCR was also used to test cases for ALK gene fusion. PNA-sequencing and RNA-sequencing had similar analytical sensitivities (< 1%), which indicates similar enrichment capabilities. The clinical sensitivity in 133 cases when detecting the common EGFR exon 19 and exon 21 mutations was 56.4% (75/133) for direct sequencing, 63.2% (84/133) for PNA-sequencing, and 65.4% (87/133) for RNA-sequencing. RT-PCR and sequencing showed 5 cases (3.8%) with ALK gene fusion. All had wild-type EGFR. For EGFR analysis of MPE, RNA-sequencing is at least as sensitive as PNA-sequencing but not limited to specific mutations. Detecting ALK fusion can be incorporated in the same RNA workflow. Therefore, RNA is a better source for comprehensive molecular diagnoses in MPE. PMID:27352172

    Primary meningeal gliomas are rare tumors composed of a heterogeneous group of neoplasms. We present 2 clinically aggressive cases of primary meningeal pleomorphic xanthoastrocytoma that clinically mimicked meningioma. One case presented in the posterior fossa of a 56-year-old woman; the other centered on the left operculum of a 35-year-old woman. These cases showed many of the classic features of pleomorphic xanthoastrocytoma, except that xanthomatous cells were rare and eosinophilic granular bodies were inconspicuous. Both cases exhibited high proliferative indices and superficially invaded the brain. One case harboring a BRAFV600E mutation disseminated to the thecal sac and showed a clinical response to the targeted BRAF inhibitor dabrafenib. These cases seem to represent an unusual primarily extra-axial presentation of pleomorphic xanthoastrocytoma and may account for at least some of the previously reported cases of primary meningeal glioma and/or glial fibrillary acidic protein–immunoreactive meningioma variants. We suggest that BRAF mutation analysis be considered in all meningeal lesions showing atypical histologic or immunohistochemical profiles, particularly those exhibiting glial differentiation, as a diagnostic aid and possible indication for targeted therapy.

    Lung cancer is a heterogeneous group of diseases. There has been much research in lung cancer over the past decade which has advanced our ability to treat these patients with a more personalized approach. The scope of this paper is to review the literature and give a broad understanding of the current molecular targets for which we currently have therapies as well as other targets for which we may soon have therapies. Additionally, we will cover some of the issues of resistance with these targeted therapies. The molecular targets we intend to discuss are epidermal growth factor receptor (EGFR), Vascular endothelial growth factor (VEGF), anaplastic large-cell lymphoma kinase (ALK), KRAS, C-MET/RON, PIK3CA. ROS-1, RET Fibroblast growth factor receptor (FGFR). Ephrins and their receptors, BRAF, and immunotherapies/vaccines. This manuscript only summarizes the work which has been done to date and in no way is meant to be comprehensive. PMID:23599689

    Our emerging understanding of the IL-2/IL-2R system opens the possibility for more specific immunotherapy of CTCL. This understanding, taken in conjunction with the ability to produce humanized antibodies to the IL-2R subunit by genetic engineering; to arm these antibodies, as well as IL-2 itself with toxins or with alpha- and beta-emitting radionuclides; and to modulate IL-2R subunits to optimize targeting of these agents provides a rational therapeutic strategy for the treatment of IL-2R-expressing CTCL. Although most of these studies were conducted in HTLV-1-associated T-cell lymphomas or CTCL, it is likely that these agents may be applicable to other T-cell lymphomas, including the anaplastic large cell lymphomas, peripheral T-cell lymphomas, and the natural killer lymphomas, because these cells express the IL-2 receptor.

    2016-01-01

    Currently, there are 19 different peripheral T-cell lymphoma (PTCL) entities recognized by the World Health Organization; however, ~70% of PTCL diagnoses fall within one of three subtypes [i.e., peripheral T-cell lymphoma not otherwise specified (PTCL-NOS), anaplastic large-cell lymphoma, and angioimmunoblastic T-cell lymphoma]. PTCL-NOS is a grouping of extra-thymic neoplasms that represent a challenging and heterogeneous subset of non-Hodgkin’s lymphomas. Research into peripheral T-cell lymphomas has been cumbersome as the lack of defining cytogenetic, histological, and molecular features has stymied diagnosis and treatment of these diseases. Similarly, the lacks of genetically manipulated murine models that faithfully recapitulate disease characteristics were absent prior to the turn of the century. Herein, we review the literature concerning existing mouse models for PTLC-NOS, while paying particular attention to the etiology of this heterogeneous disease. PMID:27725924

    2014-01-01

    Non-Hodgkin lymphomas of childhood represent a diverse group of neoplasms with different clinical, pathological, immunophenotypical and genetic features. A vast majority of childhood non-Hodgkin lymphomas could be classified into one of the three major histological subgroups: mature B-cell neoplasms, lymphoblastic lymphomas or anaplastic large cell lymphomas. Modern therapeutic strategies lead to cure in more than 80% of patients. Conversely, refractory diseases, as well as disease relapse convey a dismal prognosis. This fact requires much better stratification based on prognostic markers which would ideally recognize distinct groups of patients requiring different therapeutic regimens. Defining novel diagnostic and prognostic markers should improve diagnosis and prognosis as well as patient follow-up. It should also allow introduction of individually tailored treatment regimens in selected groups of patients with non-Hodgkin lymphomas, with the main goal of improving treatment results and decreasing short- and long-term complications.

    This article narrates a multifaceted educational journey undertaken by a medical student through a weekly SCRAPS (surgery, clinical disciplines, radiology, anatomy, psychiatry and laboratory sciences) clinico-pathological meeting held in the College of Medicine & Health Sciences at Sultan Qaboos University in Muscat, Oman. Through a presentation titled ‘Unveiling Cancer’, the multidisciplinary and interprofessional audience witnessed a simulated interaction between a medical student, a technologist peer and tutors in medicine, pathology and radiology. The presentation was based on the complexities of presentation, diagnosis and management of a patient with anaplastic large cell lymphoma, a rare type of non-Hodgkin lymphoma, in the aftermath of a bone marrow transplantation. After describing the case, the student shared with the audience a spectrum of learning objectives, which included integration in the complex world of contemporary medicine, insight into the triumphs and travails of technology (immunohistochemistry) and peer collaboration, communication and mentorship.

    The Third Annual T-cell Lymphoma Forum, held on 27-29 January 2011 in San Francisco (CA, USA), continued in the spirit of the two earlier conferences and provided a collegial venue for clinicians and scientists to discuss advances in the science and treatment of T-cell lymphomas. More than 40 experts from around the world presented updates on classification, epidemiology and prognosis; rare and T-cell lymphomas of unspecified origin, CD30(+) T-cell lymphomas; new treatment strategies; new agents and rational combinations; and transplantation. Of particular interest this year was a discussion on the link between breast implants and anaplastic large-cell lymphoma, which coincided with the US FDA announcement of this rare but noteworthy relationship. Submitted abstracts and poster presentations rounded off each of the sessions.

    Primary cutaneous T-cell lymphomas (CTCLs) encompass a clinically and biologically heterogeneous group of non-Hodgkin lymphomas (NHLs) defined by clonal proliferation of skin-homing malignant T lymphocytes and natural killer cells. They account for up to 75% to 80% of all cutaneous lymphomas. The current WHO-EORTC classification of cutaneous lymphomas with primary cutaneous manifestations lists 13 entities. The most common subtypes-mycosis fungoides, Sézary syndrome, primary cutaneous anaplastic large cell lymphoma, and lymphomatoid papulosis-which represent approximately 95% of CTCLs, will be discussed in the following review. Each entity has unique biological characteristics and clinical course. Topical and/or systemic therapies are employed based on the stage of the disease and the tempo of progression.

    In this article, we present the case of a 57-year-old man with cervical and mediastinal tumor mass, normal blood count as well as virusological status. Cervical tumor tissue biopsy revealed cells positive for CD34, CD13, LCA, CD33, and CD163 but negative for T-cell and B-cell markers, NK-cell markers, plasmacytic markers and anaplastic large cell lymphoma markers. These features were consistent with myeloid sarcoma of the neck with involvement of the mediastinum. We discussed differential diagnosis and therapy of isolated myeloid sarcoma and suggest that clinical presentation, cell morphology, complete immunophenotype, and specific genotypic lesions in some cases, must be evaluated.

    This study aimed to identify the computed tomography characteristics of treatment-naïve patients with lung adenocarcinoma and known driver mutations in EGFR, KRAS, or ALK. Patients with advanced lung adenocarcinoma (stage IIIB–IV) and known mutations in EGFR, KRAS, or ALK were assessed. The radiological findings for the main tumor and intra-thoracic status were retrospectively analyzed in each group, and the groups’ characteristics were compared. We identified 265 treatment-naïve patients with non-small-cell carcinoma, who had EGFR mutations (n = 159), KRAS mutations (n = 55), or ALK rearrangements (n = 51). Among the three groups, we evaluated only patients with stage IIIB–IV lung adenocarcinoma who had EGFR mutations (n = 126), KRAS mutations (n = 35), or ALK rearrangements (n = 47). We found that ground-glass opacity at the main tumor was significantly more common among EGFR-positive patients, compared to ALK-positive patients (p = 0.009). Lymphadenopathy was significantly more common among ALK-positive patients, compared to EGFR-positive patients (p = 0.003). Extranodal invasion was significantly more common among ALK-positive patients, compared to EGFR-positive patients and KRAS-positive patients (p = 0.001 and p = 0.049, respectively). Lymphangitis was significantly more common among ALK-positive patients, compared to EGFR-positive patients (p = 0.049). Pleural effusion was significantly less common among KRAS-positive patients, compared to EGFR-positive patients and ALK-positive patients (p = 0.046 and p = 0.026, respectively). Lung metastases were significantly more common among EGFR-positive patients, compared to KRAS-positive patients and ALK-positive patients (p = 0.007 and p = 0.04, respectively). In conclusion, EGFR mutations were associated with ground-glass opacity, KRAS-positive tumors were generally solid and less likely to metastasize to the lung and pleura, and ALK-positive tumors tended to present with lymphadenopathy, extranodal

    Methotrexate (MTX) is a commonly used anti-metabolite agent. Increased risk of lymphoproliferative disorders (LPD) in patients with rheumatoid arthritis (RA) has been documented with the prolonged use of immunosuppressive medications such as MTX. This is thought to be the result of immune dysregulation and/or chronic immune stimulation. Most cases of LPDs regress following withdrawal of the offending immunosuppressive agent. We present an interesting and rare case of CD30 and EBV positive CD8 primary cutaneous anaplastic large cell lymphoma (PC-ALCL) in a 66-year-old African American woman. Patient had been on MTX for rheumatoid arthritis (RA) which was stopped after the patient was evaluated at our institution. Patient had an incredible response to stopping immunosuppression with spontaneous regression of skin lesions and disappearance of clonal malignant cell population as evidenced on serial biopsy specimens. Primary cutaneous CD30+ LPDs constitute about 30% of the primary cutaneous T-cell lymphomas (CTLs) and includes entities such as lymphomatoid papulosis (LyP), primary cutaneous anaplastic large cell lymphoma (PC-ALCL) and other CD30+ borderline LPDs. Histopathological criteria in addition to CD30 positivity is important for identification of these conditions. Treatment options include “wait and see”, phototherapy, radiotherapy, topical agents, systemic therapy and surgical resection. Prognosis is excellent and most cases resolve spontaneously on withdrawal of immunosuppression. Refractory cases may require aggressive local treatment or systemic therapy. Brentuximab Vedontin, an anti-CD30 antibody drug conjugate (ADC), may provide additional therapeutic option in refractory cases. PMID:27335685

    Extranodal NK/T-cell lymphoma, nasal type, is a rare type of non-Hodgkin lymphoma that is most common in Asia and is driven by Epstein-Barr virus infection. These tumors usually arise in the nasal region; in rare cases they can involve extranasal sites, most often skin, with involvement of the breast being rare. Lymphomas arising adjacent to breast implants are rare, and most cases reported to date have been anaplastic lymphoma kinase (ALK)-negative anaplastic large cell lymphoma. Here we report a 41-year-old white woman with bilateral saline breast implants placed for cosmetic reasons who almost 9 years later developed painful swelling at the right-breast implant site. Excisional biopsy revealed lymphoma composed of monomorphic large cells associated with necrosis and angioinvasion. Immunohistochemical analysis showed an aberrant, NK/T-cell immunophenotype with the lymphoma cells being CD2+, CD3+, CD56+, partial CD30+, granzyme B, TIA-1+, CD4+, CD5+, CD7+, and CD8+. In situ hybridization analysis showed Epstein-Barr virus-encoded RNA within the neoplastic cells. Polymerase chain reaction analysis showed monoclonal T-cell receptor-γ chain gene rearrangement. These findings support the diagnosis of extranodal NK/T-cell lymphoma, nasal type. On the basis of our review of the literature, this case is unique. In addition, we believe this case is important to report, because it expands the spectrum of T-cell lymphomas that can be associated with breast implants and may be a forerunner of additional cases to follow.

    Poorly differentiated neuroendocrine carcinomas (NECs) are rare tumors that can arise anywhere along the gastrointestinal tract. They often present in advanced stage and portend a poor prognosis when compared to adenocarcinomas of the same stage. Characterization of these tumors is best accomplished with tissue biopsy, as peripheral tumor markers commonly used in NECs are of little utility. Therapeutic strategies often involve chemotherapeutic regimens that have been used to treat small-cell lung cancer. Recent studies have shown that programmed death-ligand 1 (PD-L1) expression within poorly differentiated NECs is a poor prognostic indicator. However, PD-L1 expression may represent a possible target for immunotherapy drugs, often called checkpoint inhibitors, such as anti-PD-1 inhibitors. PMID:28101034

    Tumor cell metabolic heterogeneity is thought to contribute to tumor recurrence, distant metastasis and chemo-resistance in cancer patients, driving poor clinical outcome. To better understand tumor metabolic heterogeneity, here we used the MCF7 breast cancer line as a model system to metabolically fractionate a cancer cell population. First, MCF7 cells were stably transfected with an hTERT-promoter construct driving GFP expression, as a surrogate marker of telomerase transcriptional activity. To enrich for immortal stem-like cancer cells, MCF7 cells expressing the highest levels of GFP (top 5%) were then isolated by FACS analysis. Notably, hTERT-GFP(+) MCF7 cells were significantly more efficient at forming mammospheres (i.e., stem cell activity) and showed increased mitochondrial mass and mitochondrial functional activity, all relative to hTERT-GFP(-) cells. Unbiased proteomics analysis of hTERT-GFP(+) MCF7 cells directly demonstrated the over-expression of 33 key mitochondrial proteins, 17 glycolytic enzymes, 34 ribosome-related proteins and 17 EMT markers, consistent with an anabolic cancer stem-like phenotype. Interestingly, MT-CO2 (cytochrome c oxidase subunit 2; Complex IV) expression was increased by >20-fold. As MT-CO2 is encoded by mt-DNA, this finding is indicative of increased mitochondrial biogenesis in hTERT-GFP(+) MCF7 cells. Importantly, most of these candidate biomarkers were transcriptionally over-expressed in human breast cancer epithelial cells in vivo. Similar results were obtained using cell size (forward/side scatter) to fractionate MCF7 cells. Larger stem-like cells also showed increased hTERT-GFP levels, as well as increased mitochondrial mass and function. Thus, this simple and rapid approach for the enrichment of immortal anabolic stem-like cancer cells will allow us and others to develop new prognostic biomarkers and novel anti-cancer therapies, by specifically and selectively targeting this metabolic sub-population of aggressive cancer cells. Based on our proteomics and functional analysis, FDA-approved inhibitors of protein synthesis and/or mitochondrial biogenesis, may represent novel treatment options for targeting these anabolic stem-like cancer cells.

    Lung cancer is the most frequent and lethal human cancer in the world. Because is still an unsolved health issue, new compounds or therapeutic strategies are urgently needed. Furoxans are presented as potentials candidates for lung cancer treatment. Accordingly, we evaluated the efficacy of a benzofuroxan derivative, BFD-22, alone and combined with sorafenib against NCI-H460 cell line. We showed that BFD-22 has cytotoxic effects on the NCI-H460 cells. Importantly, the Combination Index (CI) evaluation revels that BFD-22 combined with sorafenib has a stronger cytotoxic effect. In addition, the combination induces apoptosis through extrinsic pathway, leading to TRAIL-R1/DR4-triggered apoptosis. Furthermore, BFD-22 combined with sorafenib increases ROS production and simultaneously reduces perlecan expression in the NCI-H460 cells. In accordance, tumor cells were arrested in the S-phase, and these anti-proliferative effects also inhibit cell migration. This is the first study reporting an advantage of BFD-22 combined with sorafenib as a new therapeutic strategy in the fight against lung cancer.

  19. Expression of TRAF1 and nuclear c-Rel distinguishes primary mediastinal large cell lymphoma from other types of diffuse large B-cell lymphoma.

    Primary mediastinal large B-cell lymphoma (PMLBCL) is a recently identified subtype of diffuse large B-cell lymphoma (DLBCL) that is difficult to distinguish from other types of DLBCL on the basis of histologic features alone. We recently identified a molecular signature of PMLBCL that is distinct from other forms of DLBCL but shares features with classical Hodgkin lymphoma. This signature includes activation of the nuclear factor kappaB (NFkappaB) signaling pathway, which in part, acts through nuclear translocation of c-Rel containing NFkappaB transcriptional complexes, and subsequent expression of NFkappaB target genes such as tumor necrosis factor receptor-associated factor-1 (TRAF1). Using standard immunohistochemical techniques, we examined 251 large B-cell lymphomas (78 cases of PMLBCL and 173 cases of other types of DLBCL) to determine whether the expression patterns of c-Rel and TRAF1 could reliably distinguish between PMLBCL and other types of DLBCL. Robust nuclear c-Rel was present in 31 of 48 (65%) cases of PMLBCL and 28 of 160 (18%) cases of DLBCL. In addition, cytoplasmic TRAF1 expression was seen in 48 of 78 (62%) cases of PMLBCL, but only 20 of 173 (12%) cases of DLBCL. Finally, the combined expression of nuclear c-Rel and TRAF1 was seen in 24 of 45 cases (53%) of PMLBCL, but in only 3 of 156 cases (2%) of other types of DLBCL. Thus, the combined nuclear localization of c-Rel and the cellular expression of TRAF1 is a highly specific (specificity=98%) means to distinguish PMLBCL from DLBCL that is readily applicable to routine surgical pathology practice.
