Abstract
Predominantly nodal is the most common clinical presentation of peripheral T- (and NK-) cell lymphomas (PTCL), which comprise three main groups of diseases: (i) systemic anaplastic large cell lymphomas (ALCL), whether positive or negative for anaplastic lymphoma kinase (ALK); (ii) follicular helper T-cell lymphomas (TFHL); and (iii) PTCL, not otherwise specified (NOS). Recent advances in the genomic and molecular characterization of PTCL, with enhanced understanding of pathobiology, have translated into significant updates in the latest 2022 classifications of lymphomas. ALK-negative ALCL is now recognized to be genetically heterogeneous, with identification of DUSP22 rearrangements in approximately 20-30% of cases, correlated with distinctive pathological and biological features. The notion of cell-of-origin as an important determinant of the classification of nodal PTCL is best exemplified by TFHL, considered as one disease or a group of related entities, sharing oncogenic pathways with frequent recurrent epigenetic mutations as well as a relationship to clonal hematopoiesis. Data are emerging to support that a similar cell-of-origin concept might be relevant to characterize meaningful subgroups within PTCL, NOS, based on cytotoxic and/or Th1 versus Th2 signatures. The small group of primary nodal Epstein-Barr virus-positive lymphomas of T- or NK-cell derivation, formerly considered PTCL, NOS, is now classified separately, due to distinctive features, and notably an aggressive course. This review summarizes current knowledge of the pathology and biology of nodal-based PTCL entities, with an emphasis on recent findings and underlying oncogenic mechanisms.

Wu R, Lim MS. Updates in pathobiological aspects of anaplastic large cell lymphoma. Front Oncol 2023; 13:1241532.

Abstract
Anaplastic large cell lymphomas (ALCL) encompass several distinct subtypes of mature T-cell neoplasms that are unified by the expression of CD30 and anaplastic cytomorphology. Identification of the cytogenetic abnormality t(2;5)(p23;q35) led to the subclassification of ALCLs into ALK+ ALCL and ALK- ALCL. According to the most recent World Health Organization (WHO) Classification of Haematolymphoid Tumours as well as the International Consensus Classification (ICC) of Mature Lymphoid Neoplasms, ALCLs encompass ALK+ ALCL, ALK- ALCL, and breast implant-associated ALCL (BI-ALCL). Approximately 80% of systemic ALCLs harbor rearrangement of ALK, with NPM1 being the most common partner gene, although many other fusion partner genes have been identified to date. ALK- ALCLs represent a heterogeneous group of lymphomas with distinct clinical, immunophenotypic, and genetic features. A subset harbor recurrent rearrangement of genes, including TYK2, DUSP22, and TP63, with a proportion for which genetic aberrations have yet to be characterized. Although primary cutaneous ALCL (pc-ALCL) is currently classified as a subtype of primary cutaneous T-cell lymphoma, due to the large anaplastic and pleomorphic morphology together with CD30 expression in the malignant cells, this review also discusses the pathobiological features of this disease entity. Genomic and proteomic studies have contributed significant knowledge elucidating novel signaling pathways that are implicated in ALCL pathogenesis and represent candidate targets of therapeutic interventions. This review aims to offer perspectives on recent insights regarding the pathobiological and genetic features of ALCL.

Leukaemic Presentation of Small-Cell Alk-Positive Anaplastic Large Cell Lymphoma in a Young Woman-Report of a Case with 9-Year Survival. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1628.

Abstract
Anaplastic large cell lymphoma (ALCL) with leukaemic presentation (either ab initio or along the course of the disease) has been rarely reported. Irrespective of ALK expression in the neoplastic cells, it features a dismal prognosis. We report a rare case of leukaemic, small cell variant ALK-positive ALCL with 9-year survival in a young woman who was treated upfront with corticosteroids and standard chemotherapy, and review thoroughly the previously published cases. Such an unexpected, good outcome hints at the existence of different clinical subgroups in the leukaemic variant of ALK-positive ALCL.

Abstract
Anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKIs) show potent efficacy in several ALK-driven tumors, but the development of resistance limits their long-term clinical impact. Although resistance mechanisms have been studied extensively in ALK-driven non-small cell lung cancer, they are poorly understood in ALK-driven anaplastic large cell lymphoma (ALCL). Here, we identify a survival pathway supported by the tumor microenvironment that activates phosphatidylinositol 3-kinase γ (PI3K-γ) signaling through the C-C motif chemokine receptor 7 (CCR7). We found increased PI3K signaling in patients and ALCL cell lines resistant to ALK TKIs. PI3Kγ expression was predictive of a lack of response to ALK TKI in patients with ALCL. Expression of CCR7, PI3Kγ, and PI3Kδ were up-regulated during ALK or STAT3 inhibition or degradation and a constitutively active PI3Kγ isoform cooperated with oncogenic ALK to accelerate lymphomagenesis in mice. In a three-dimensional microfluidic chip, endothelial cells that produce the CCR7 ligands CCL19/CCL21 protected ALCL cells from apoptosis induced by crizotinib. The PI3Kγ/δ inhibitor duvelisib potentiated crizotinib activity against ALCL lines and patient-derived xenografts. Furthermore, genetic deletion of CCR7 blocked the central nervous system dissemination and perivascular growth of ALCL in mice treated with crizotinib. Thus, blockade of PI3Kγ or CCR7 signaling together with ALK TKI treatment reduces primary resistance and the survival of persister lymphoma cells in ALCL.

Abstract
Peripheral T-cell lymphomas (PTCL) comprised more than 30 rare heterogeneous entities, representing 10 to 15% of adult non-Hodgkin lymphomas. Although their diagnosis is still mainly based on clinical, pathological, and phenotypic features, molecular studies have allowed for a better understanding of the oncogenic mechanisms involved and the refinement of many PTCL entities in the recently updated classifications. The prognosis remains poor for most entities (5-year overall survival < 30%), with current conventional therapies based on anthracyclin-based polychemotherapy regimen, despite many years of clinical trials. The recent use of new targeted therapies appears to be promising for relapsed/refractory patients, such as demethylating agents in T-follicular helper (TFH) PTCL. However further studies are needed to evaluate the proper combination of these drugs in the setting of front-line therapy. In this review, we will summarize the oncogenic events for the main PTCL entities and report the molecular targets that have led to the development of new therapies. We will also discuss the development of innovative high throughput technologies that aid the routine workflow for the histopathological diagnosis and management of PTCL patients.

Abstract
Anaplastic lymphoma kinase (ALK)-positive large B-cell lymphoma (LBCL) is a very rare type of LBCL with an aggressive clinical course and poor prognosis. This diagnosis can be challenging given the varied morphology (immunoblastic, plasmablastic, or anaplastic), frequent lack of B-cell antigens, and especially in cases with expression of epithelial antigens. Here, we report a case of ALK-positive LBCL with unusual expression of 4 epithelial-associated markers (AE1/AE3, CK8/18, EMA, and GATA3) and novel poly(A) binding protein cytoplasmic 1 (PABPC1)::ALK fusion which has not been previously reported in this entity. This case also emphasizes the use of comprehensive immunophenotyping that includes multiple lineage-specific antibodies when faced with a malignancy without a clear differentiation to avoid misdiagnosis. This case only achieved partial response to combination chemotherapy, radiation, and ALK inhibitor regimens, and furthers our understanding of this uncommon lymphoma.

Abstract
Mammalian poly A-binding proteins (PABPs) are highly conserved multifunctional RNA-binding proteins primarily involved in the regulation of mRNA translation and stability, of which PABPC1 is considered a central regulator of cytoplasmic mRNA homing and is involved in a wide range of physiological and pathological processes by regulating almost every aspect of RNA metabolism. Alterations in its expression and function disrupt intra-tissue homeostasis and contribute to the development of various tumors. There is increasing evidence that PABPC1 is aberrantly expressed in a variety of tumor tissues and cancers such as lung, gastric, breast, liver, and esophageal cancers, and PABPC1 might be used as a potential biomarker for tumor diagnosis, treatment, and clinical application in the future. In this paper, we review the abnormal expression, functional role, and molecular mechanism of PABPC1 in tumorigenesis and provide directions for further understanding the regulatory role of PABPC1 in tumor cells.

Abstract
Inflammatory myofibroblastic tumours (IMT) are spindle cell neoplasms most commonly seen in the lungs, with a wide variety of less common extrapulmonary sites including the mesentery, omentum, and intrabdominal sites. On cytological evaluation, these tumours can be difficult to diagnose, given the morphological mimics of other submucosal spindle cell neoplasms, which may be compounded by the relatively small amount of tissue and the uncommon nature of the diagnosis. Immunohistochemical staining and molecular studies for the Anaplastic lymphoma kinase (ALK) gene can prove useful for diagnosing this tumour. We present the cytological features of an IMT occurring in the rectum, the differential diagnoses, useful immunohistochemical staining patterns and the additional finding of a novel ALK-fusion in this entity.

Abstract
As a member of the phospholipase family, phospholipase C beta 1 (PLCB1) is involved in phospholipid hydrolysis and is frequently upregulated in human cancer. However, little is known about the role of PLCB1 in cholangiocarcinoma (CCA). In this study, we uncover a role for PLCB1 in CCA progression and identify the underlying mechanisms. Both human CCA tissues and CCA cell lines expressed high levels of PLCB1. PLCB1 promoted tumor development and growth in various CCA mouse models, including transposon-based tumorigenesis models. PLCB1 activated PI3K/AKT signaling to induce CCA cells to undergo epithelial-to-mesenchymal transition (EMT). Mechanistically, PABPC1 interacted with PLCB1 and PI3K to amplify PLCB1-mediated EMT via PI3K/AKT/GSK3β/Snail signaling. Ectopic PLCB1 induced resistance to treatment with gemcitabine combined with cisplatin, which could be reversed by the AKT inhibitor MK2206. PLCB1 expression was regulated by miR-26b-5p through direct interaction with PLCB1 3'UTR. Collectively, these data identify a PLCB1-PI3K-AKT signaling axis vital for CCA development and EMT, suggesting that AKT can be used as a therapeutic target to overcome chemotherapy resistance in CCA patients with high PLCB1 expression. SIGNIFICANCE: PLCB1 functions as an oncogenic driver in cholangiocarcinoma development that confers an actionable therapeutic vulnerability to AKT inhibition.

JAK2 Rearrangements Are a Recurrent Alteration in CD30+ Systemic T-Cell Lymphomas With Anaplastic Morphology. Am J Surg Pathol 2021; 45:895-904.

Abstract
Peripheral T-cell lymphoma (PTCL) comprises a heterogenous group of rare mature T-cell neoplasms. While some PTCL subtypes are well-characterized by histology, immunophenotype, and recurrent molecular alterations, others remain incompletely defined. In particular, the distinction between CD30+ PTCL, not otherwise specified and anaplastic lymphoma kinase (ALK)-negative anaplastic large cell lymphoma can be subject to disagreement. We describe a series of 6 JAK2 rearrangements occurring in a cohort of 97 CD30+ ALK- PTCL (6%), assembled after identifying an index case of a novel PABPC1-JAK2 fusion in a case of ALK- anaplastic large cell lymphoma with unusual classic Hodgkin lymphoma (CHL)-like features. Fusions were identified using a comprehensive next-generation sequencing based assay performed between 2013 and 2020. Five of 6 cases (83%) showed JAK2 rearrangements with 4 novel partners: TFG, PABPC1, ILF3, and MAP7, and 1 case demonstrated a previously described PCM1-JAK2 fusion. By morphology, all cases showed anaplastic large cells and multinucleated Reed-Sternberg-like cells within a polymorphous inflammatory background with frequent eosinophilia reminiscent of CHL. By immunohistochemistry, atypical large cells expressed CD30 with coexpression of at least 1 T-cell marker, aberrant loss of at least 1 T-cell marker and, in 4 of 5 cases stained (80%), unusual CD15 coexpression. These findings suggest that a subset of CD30+ ALK- systemic PTCL with anaplastic morphology carry JAK2 rearrangements, some of which appear to show CHL-like morphologic features. The presence of JAK2 rearrangements in cases of CD30+ PTCL augments current classification and may provide a therapeutic target via JAK2 inhibition.

Minimal Residual Disease Monitoring Using a 3'ALK Universal Probe Assay in ALK-Positive Anaplastic Large-Cell Lymphoma: ddPCR, an Attractive Alternative Method to Real-Time Quantitative PCR. J Mol Diagn 2020; 23:131-139. [PMID: 33246076 DOI: 10.1016/j.jmoldx.2020.11.002] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Revised: 10/06/2020] [Accepted: 11/03/2020] [Indexed: 12/20/2022] Open
Abstract
In ALK-positive anaplastic large-cell lymphomas, positive qualitative PCR for NPM1-anaplastic lymphoma kinase (ALK) in peripheral blood and/or bone marrow at diagnosis and during treatment are associated with a higher risk of treatment failure. Real-time quantitative PCR allows identification of very high risk patients. However, this latter technique initially designed for patients with lymphomas carrying the most frequent NPM1-ALK translocation necessitates calibration curves, limiting interlaboratory reproducibility. An ALK universal quantitative PCR based on 3'ALK transcript amplification was designed to allow the detection of all ALK fusion transcripts. The absolute concordance of 3'ALK quantitative PCR results were validated with the routine NPM1-ALK qualitative and quantitative PCR on 46 samples. The universality of ALK fusion transcript detection also was validated on TPM3-, ALO17-, and ATIC-ALK-positive samples, and the EML4-ALK-positive cell line. Digital droplet PCR using the 3'ALK universal probe showed highly concordant results with 3'ALK universal quantitative PCR. A major benefit of digital droplet PCR is a reduced experimental set-up compared with quantitative PCR, without generation of standard curves, leading to a reliable protocol for multilaboratory validation in multicenter clinical trials essential for this rare pathology. Our ALK universal method could be used for the screening of ALK fusion transcripts in liquid biopsy specimens of other ALK-positive tumors, including non-small cell lung carcinomas.

Abstract
Peripheral T-cell lymphomas (PTCLs) represent a heterogeneous group of uncommon malignancies derived from mature T cells and usually characterised by an aggressive clinical course. Their clinical presentation, localisation and pattern of dissemination are highly variable, but the majority of cases present as nodal diseases. The recently revised classification of lymphomas has incorporated many new molecular genetic data derived from gene expression profiling and next generation sequencing studies, which refine the definition and diagnostic criteria of several entities. Nevertheless, the distinction of PTCL from various reactive conditions, and the diagnosis of PTCL subtypes remains notably challenging. Here, an updated summary of the clinicopathological and molecular features of the most common nodal-based PTCLs (angioimmunoblastic T-cell lymphoma and other nodal lymphomas derived from follicular T helper cells, anaplastic large cell lymphomas and peripheral T-cell lymphoma, not otherwise specified) is presented. Practical recommendations in the diagnostic approach to nodal T-cell lymphoproliferations are presented, including indications for the appropriate use and interpretation of ancillary studies. Finally, we discuss commonly encountered diagnostic problems, including pitfalls and mimics in the differential diagnosis with various reactive conditions, and the criteria that allow proper identification of distinct PTCL entities.

Abstract
Anaplastic large cell lymphomas (ALCLs) encompass a group of CD30(+) non-Hodgkin T-cell lymphomas. While the different subtypes of ALCLs may share overlapping clinical patient demographics as well as histological and immunohistochemical phenotypes, these tumours can drastically differ in clinical behaviour and genetic profiles. Currently, four distinct ALCL entities are recognised in the 2016 WHO classification: anaplastic lymphoma kinase (ALK)(+), ALK(-), primary cutaneous and breast implant-associated. ALK(+) ALCL demonstrates a spectrum of cell cytology ranging from small to large lymphoma cells and characteristic 'hallmark' cells. ALK(+) ALCL consistently demonstrates ALK gene rearrangements and carries a favourable prognosis. ALK(-) ALCL morphologically and immunohistochemically mimics ALK(+) ALCL but lacks the ALK gene rearrangement. ALK(-) ALCLs are associated with variable prognoses depending on specific gene rearrangements; while DUSP22-rearranged cases have favourable outcomes similar to ALK(+) ALCLs, cases with p63 rearrangements carry a dismal prognosis and 'triple-negative' cases (those lacking ALK, DUSP22 and TP63 rearrangements) have an intermediate prognosis. Primary cutaneous ALCL presents as a skin lesion, lacks the ALK gene translocation and carries a favourable prognosis, similar or superior to ALK(+) ALCL. Breast implant-associated ALCL presents as a seroma with a median of 8-10 years after implant placement, lacks the ALK gene translocation and has an overall favourable but variable prognosis, depending on extent of disease at diagnosis and treatment. In this review, we present the clinical, pathological and genetic features of the ALCLs with emphasis on practical points and differential diagnoses for practising pathologists.
