Abstract
In this study, we investigated the role of calreticulin (CALR) in the pathogenesis of natural killer/T-cell lymphoma (NKTCL). CALR expression was significantly higher in the NKTCL tissues than normal control tissues in the GSE80632 dataset. High CALR expression correlated with poorer overall survival of NKTCL patients (P = 0.0248). CALR mRNA and protein levels were significantly higher in NKTCL cell lines (NK92, SNK6, and SNT8) than normal NK cells. CALR-silenced SNK6 cells generated significantly smaller xenograft tumors in immunodeficient NCG mice than control SNK6 cells. CALR-knockdown NKTCL cells showed significantly less in vitro proliferation and Transwell migration than the controls. CALR knockdown inhibited G1-to-S phase cell cycle progression by increasing the levels of p27 cell cycle inhibitor and reducing the levels of cyclin E2 and cyclin-dependent kinase 2 (CDK2). CALR knockdown inhibited epithelial-to-mesenchymal transition (EMT) by decreasing the levels of β-catenin and TCF/ZEB1 and upregulating E-cadherin. These data demonstrate that CALR regulates the growth and progression of NKTCL cells by modulating G1-to-S cell cycle progression and EMT.

Abstract
Objective: The prognostic nutritional index (PNI) is a significant prognostic factor in diffuse large B cell lymphoma, follicular lymphoma, and other malignancies. The current study aimed to explore its prognostic role in extranodal natural killer/T cell lymphoma (ENKTL). Methods: Patients diagnosed with ENKTL and treated during 2002 and 2018 (n = 184) were retrospectively recruited. PNI was calculated from albumin concentration (g/L) and total lymphocyte count (*109/L). The association of PNI and overall survival (OS) or progression-free survival (PFS) was assessed in univariate analysis and multivariate Cox regression validated by the 10-fold cross-validation method. Results: Survival analyses showed that both OS and PFS differed significantly between PNI groups stratified by a cutoff value of 49.0. The 3- and 5-year OS were 42.5 and 36.3% in the low-PNI (PNI < 49) subgroup and 70.6% and 63.9% (P < 0.001) in the high-PNI (PNI ≥ 49) subgroup, respectively. The corresponding PFS showed a similar pattern (38.4, 32.4 vs. 64.8, 54.0%, P < 0.001). Multivariate analysis indicated that PNI was significantly independent for both OS (HR = 0.517, 95% CI = 0.322–0.831, P = 0.006) and PFS (HR = 0.579, 95% CI = 0.373–0.899, P = 0.015). Furthermore, integrating PNI into the models of IPI (International Prognostic Index), KPI (Korean Prognostic Index), and PINK (prognostic index of natural killer lymphoma) could improve the area under the curve (AUC) and reduce the integrated Brier score (IBS) and Akaike Information Criterion (AIC) value of each model. Conclusion: PNI was a significant prognostic indicator for ENKTL.

Abstract
Prognosis of patients with localized nasal extranodal natural killer/T‐cell lymphoma, nasal type (ENKL) has been improved by non‐anthracycline‐containing treatments such as concurrent chemoradiotherapy (CCRT). However, some patients experience early disease progression. To clarify the clinical features and outcomes of these patients, data from 165 patients with localized nasal ENKL who were diagnosed between 2000 and 2013 at 31 institutes in Japan and who received radiotherapy with dexamethasone, etoposide, ifosfamide, and carboplatin (RT‐DeVIC) were retrospectively analyzed. Progression of disease within 2 years after diagnosis (POD24) was used as the definition of early progression. An independent dataset of 60 patients with localized nasal ENKL who received CCRT at Samsung Medical Center was used in the validation analysis. POD24 was documented in 23% of patients who received RT‐DeVIC and in 25% of patients in the validation cohort. Overall survival (OS) from risk‐defining events of the POD24 group was inferior to that of the reference group in both cohorts (P < .00001). In the RT‐DeVIC cohort, pretreatment elevated levels of serum soluble interleukin‐2 receptor (sIL‐2R), lactate dehydrogenase, C‐reactive protein, and detectable Epstein‐Barr virus DNA in peripheral blood were associated with POD24. In the validation cohort, no pretreatment clinical factor associated with POD24 was identified. Our study indicates that POD24 is a strong indicator of survival in localized ENKL, despite the different CCRT regimens adopted. In the treatment of localized nasal ENKL, POD24 is useful for identifying patients who have unmet medical needs.

Abstract
Extranodal natural killer/T-cell lymphomas (NK/TL), rare in Europe, are Epstein-Barr virus (EBV) associated lymphomas with poor outcomes. Here, we determined the virus type and analyzed the EBV latent membrane protein-1 (LMP1) gene sequence in NK/TL from French patients. Six clones of viral LMP1 were sequenced by Sanger technology in blood from 13 patients before treatment with an l-asparaginase based regimen and, for 8 of them, throughout the treatment. Blood LMP1 sequences from 21 patients without any known malignancy were tested as controls. EBV Type A was identified for 11/13 patients and for all controls. Before treatment, a clonal LMP1 gene containing a 30 bp deletion (del30) was found in 46.1% of NK/TL and only in 4.8% of controls. Treatment was less effective in these patients who died more rapidly than the others. Patients with a deleted strain evolving toward a wild-type strain during treatment reached complete remission. The LMP1 gene was sequenced by highly sensitive next-generation sequencing technology in five NK/TL nasopharyngeal biopsies, two of them originating from the previous patients. Del30 was present in 100% of the biopsies; two viruses at least coexisted in three biopsies. These results suggest that del30 may be associated with poor prognosis NK/TL and that strain evolution could be used as a potential marker to monitor treatment.

Abstract
The expansion of myeloid-derived suppressor cells (MDSCs) and its correlation with advanced disease stage have been shown in solid cancers. Here, we investigated the functional features and clinical significance of MDSCs in extranodal NK/T cell lymphoma (ENKL). A higher percentage of circulating HLA-DR−CD33+CD11b+ MDSCs was observed in ENKL patients than in healthy controls (P < 0.05, n = 32) by flow cytometry analysis. These MDSCs from ENKL patients (ENKL-MDSCs) consisted of CD14+ monocytic (Mo-MDSCs, >60 %) and CD15+ granulocytic (PMN-MDSCs, <20 %) MDSCs. Furthermore, these ENKL-MDSCs expressed higher levels of Arg-1, iNOS and IL-17 compared to the levels of MDSCs from healthy donors, and they expressed moderate levels of TGFβ and IL-10 but lower levels of CD66b. The ENKL-MDSCs strongly suppressed the anti-CD3-induced allogeneic and autologous CD4 T cell proliferation (P < 0.05), but they only slightly suppressed CD8 T cell proliferation (P > 0.05). Interestingly, ENKL-MDSCs inhibited the secretion of IFNγ but promoted IL-10, IL-17 and TGFβ secretion as well as Foxp3 expression in T cells. The administration of inhibitors of iNOS, Arg-1 and ROS significantly reversed the suppression of anti-CD3-induced T cell proliferation by MDSCs (P < 0.05). Importantly, based on multivariate Cox regression analysis, the HLA-DR−CD33+CD11b+ cells and CD14+ Mo-MDSCs were independent predictors for disease-free survival (DFS, P = 0.013 and 0.016) and overall survival (OS, P = 0.017 and 0.027). Overall, our results identified for the first time that ENKL-MDSCs (mainly Mo-MDSCs) have a prognostic value for patients and a suppressive function on T cell proliferation.

An unusual presentation of NK/T-cell lymphoma, nasal-type in the United States. Am J Otolaryngol 2015; 36:80-3.

Abstract
INTRODUCTION NK/T-cell lymphoma (NKCL), nasal-type is rare in the United States, representing only 1.5% of non-Hodgkin lymphomas. Classically, patients initially present with nasal obstruction (70%), caused by invasion of the localized lesion into the sinuses and nasal cavities. Initial presentation with persistent sore throat and odynophagia due to oropharyngeal tumor extension is rare, and thus, is often overlooked as viral or bacterial pharyngitis. By studying a case of NKTCL nasal type, we emphasize the need to apply high clinical suspicion for NKTCL, nasal type for early diagnosis and improved survival. METHODS A case report of a rare presentation of NKTCL, nasal-type is discussed. A literature review is provided to define clinical signs crucial for early diagnosis, appropriate work-up, and expedient treatment of this aggressive, rapidly progressive malignancy. RESULTS In the present case, a 25year-old healthy male presented with a 2-week history of sore throat and odynophagia. On exam, the patient had an ulcerative lesion of the soft palate, an enlarged uvula, and tonsillar exudate with tender submandibular lymphadenopathy. After the patient failed to respond to antibiotic therapy for presumptive pharyngitis, a biopsy of the oropharyngeal tissue was completed, which identified necrotizing sialometaplasia. High clinical suspicion led to repeat deep-tissue biopsy, where a final diagnosis of NKTCL, nasal type was made. The patient then began definitive treatment with chemotherapy and radiation. CONCLUSIONS High clinical suspicion is key to early diagnosis and improved survival of NKTCL, nasal-type. Otolaryngologists who encounter prolonged, complicated cases of pharyngitis or necrotizing sialometaplasia should consider a diagnosis of NKTCL, nasal-type, in order to prevent rapid disease progression.

Abstract
PURPOSE To describe the clinical presentation, diagnosis and treatment of periorbital extranodal natural killer/T-cell lymphoma, nasal type. METHODS Case series of three patients with periorbital involvement of extranodal natural killer/T-cell lymphoma, nasal type, of whom clinical data, orbital imaging and immunohistochemical analysis were collected. For the purpose of this study, all histopathological and immunohistochemical slides were re-examined. RESULTS All patients presented with painless eyelid swelling and a history of sinonasal disease, of whom one with bilateral panuveitis, not responding to systemic antibiotics. Extraocular muscle involvement was present in 2 cases upon presentation and in 1 case later on. Initial paranasal and orbital biopsies were negative in 2 patients, with only the second orbital biopsy leading to the diagnosis. Natural killer/T-cell and cytotoxic markers were present in all cases, as well as Epstein-Barr virus encoded RNA in situ hybridization. The patients died respectively 5, 9 and 35 months from diagnosis despite treatment with chemotherapy and radiotherapy. CONCLUSION Extranodal natural killer/T-cell lymphoma, nasal type, should be suspected in a painless periorbital cellulitis with chronic sinusitis, not responding to conventional therapy. A high index of suspicion is necessary in biopsies showing angiodestruction and necrosis. Epstein-Barr virus encoded RNA in situ hybridization and expert hematopathologist consultation is necessary to decrease the delay in diagnosis.

Abstract
Mature natural killer (NK) cell neoplasms are classified by the World Health Organization into NK/T cell lymphoma, nasal type (NKTCL), aggressive NK-cell leukemia (ANKCL) and chronic lymphoproliferative disorders of NK-cells, the latter being considered provisionally. NKTCL and ANKCL are rare diseases, with higher prevalence in Asia, Central and South America. Most NKTCL present extranodal, as a destructive tumor affecting the nose and upper aerodigestive tract (nasal NKTCL) or any organ or tissue (extranasal NKTCL) whereas ANKCL manifests as a systemic disease with multiorgan involvement and naturally evolutes to death in a few weeks. The histopathological hallmark of these aggressive NK-cell tumors is a polymorphic neoplastic infiltrate with angiocentricity, angiodestruction and tissue necrosis. The tumor cells have cytoplasmatic azurophilic granules and usually show a CD45(+bright), CD2(+), sCD3(-), cytCD3epsilon(+), CD56(+bright), CD16(−/+), cytotoxic granules molecules(+) phenotype. T-cell receptor genes are in germ-line configuration. Epstein-Barr virus (EBV) -encoded membrane proteins and early region EBV RNA are usually detected on lymphoma cells, with a pattern suggestive of a latent viral infection type II. Complex chromosomal abnormalities are frequent and loss of chromosomes 6q, 11q, 13q, and 17p are recurrent aberrations. The rarity of the NK-cell tumors limits our ability to standardize the procedures for the diagnosis and clinical management and efforts should be made to encourage multi-institutional registries.

Abstract
PURPOSE To explore the efficacy and safety of L-asparaginase in newly-diagnosed extranodal nature killer (NK)/T -cell lymphoma (ENKTL), we conducted a prospective phase II study of L-asparaginase, cyclophosphamide, vincristine, doxorubicin and dexamethasone (CHOP-L) regimen in combination with radiotherapy. PATIENTS AND METHODS Patients with newly diagnosed ENKTL and an ECOG performance status of 0 to 2 were eligible for enrollment. Treatment included 6-8 cycles of CHOP-L (cyclophosphamide, 750 mg/m(2) day 1; vincristine, 1.4 mg/m(2) day 1 (maximal dose 2 mg), doxorubicin 50 mg/m(2) day 1; dexamethasone 10 mg days 1-8; L-asparaginase 6000 u/m(2) days 2-8). Radiotherapy was scheduled after 4-6 cycles of CHOP-L regimen, depending on stage and primary anatomic site. The primary endpoint was complete response (CR) rate. RESULTS A total of 38 eligible patients were enrolled. The median age was 40.5 years (range, 15 to 71 years). Their clinical characteristics were male to female ratio, 24:14; Ann Arbor stage I, 20; II, 11; III, 3; IV, 4. CR and overall response rates were 81.6% (95% CI, 69.3% to 93.9%) and 84.2%, respectively. With a median follow-up of 25 months, the 2-year overall survival, progression-free survival and disease-free survival rates were 80.1% (95%CI, 73.3% to 86.9%), 81% (95%CI, 74.5% to 87.5%) and 93.6% (95%CI, 89.3% to 97.9%), respectively. The major adverse events were myelosuppression, liver dysfunction, and digestive tract toxicities. Grade 3 to 4 leukopenia and neutropenia were 76.3% and 84.2%, respectively. No treatment-related death was observed. CONCLUSION CHOP-L chemotherapy in combination with radiotherapy is a safe and highly effective treatment for newly diagnosed ENKTL.

Abstract
PURPOSE To determine the occurrence, clinical course and outcome of our patients with natural killer/T-cell lymphoma (NKTCL), nasal type. The nasal type of natural killer/T-cell lymphoma (NKTCL), is rare in the European population but is more frequent in Asia, Central and South America where it accounts for 15-20% of all non-Hodgkin lymphomas (NHL). This type of lymphoma is characterized by tissue necrosis and destruction of the nasal cavity and upper aero-digestive tract. The disease is closely associated with Epstein-Barr virus (EBV) infection and has an aggressive clinical course, poor clinical outcome and high resistance to chemotherapy. PATIENTS 63 patients with NHL were treated in our department between 2006 and 2011. Eleven patients were diagnosed with extranodal lymphoma, 6 in the area of head and neck. Three of them belonged to NKTCL, nasal type group (4.7%), 1 was diffuse large B cell lymphoma and 2 were marginal zone lymphomas. CONCLUSION Two out of 3 patients with nasal type NKTCL, had extremely aggressive disease resistant to applied chemotherapy (anthracycline containing regimen), while 1 patient remains in complete remission 6 years after diagnosis.

Abstract
Background Extranodal natural killer/T-cell lymphoma (ENKL) has heterogeneous clinical manifestations and prognosis. This study aims to evaluate the prognostic impact of absolute monocyte count (AMC) in ENKL, and provide some immunologically relevant information for better risk stratification in patients with ENKL. Methods Retrospective data from 163 patients newly diagnosed with ENKL were analyzed. The absolute monocyte count (AMC) at diagnosis was analyzed as continuous and dichotomized variables. Independent prognostic factors of survival were determined by Cox regression analysis. Results The AMC at diagnosis were related to overall survival (OS) and progression-free survival (PFS) in patients with ENKL. Multivariate analysis identified AMC as independent prognostic factors of survival, independent of International Prognostic Index (IPI) and Korean prognostic index (KPI). The prognostic index incorporating AMC and absolute lymphocyte count (ALC), another surrogate factor of immune status, could be used to stratify all 163 patients with ENKL into different prognostic groups. For patients who received chemotherapy followed by radiotherapy (102 cases), the three AMC/ALC index categories identified patients with significantly different survivals. When superimposed on IPI or KPI categories, the AMC/ALC index was better able to identify high-risk patients in the low-risk IPI or KPI category. Conclusion The baseline peripheral monocyte count is shown to be an effective prognostic indicator of survival in ENKL patients. The prognostic index related to tumor microenvironment might be helpful to identify high-risk patients with ENKL.

Abstract
We now recognize that the Epstein-Barr virus (EBV), which is a member of the γ- herpesvirus family, plays a pivotal role in the development of several lymphomas and lymphoproliferative disorders that include B-cell, T-cell and NK-cell processes. While over recent years, EBV associated lymphomas that arise in patients with known defects in cellular immunity are relatively well characterized, these diseases are becoming increasingly recognized in patients without overt immunodeficiency. Improved understanding of the biology of these lymphomas including elucidating the role that EBV plays in their pathogenesis has paved the way for improved therapies targeted at critical signaling pathways as well as the development of novel cellular therapies. In this review, we focus on recent progress that has been made in the biology and treatment of the rare EBV-associated disorder lymphomatoid granulomatosis (LYG) and also discuss other EBV-associated processes that occur in both immunocompetent and immunocompromised hosts.

Abstract
Extranodal NK/T-cell lymphoma, nasal type, is a lymphoproliferative disorder originating from peripheral T-cells or natural killer (NK) cells. While it is a rare disease in Europe, it is more frequent in Asia and South America. It is associated with Epstein-Barr virus (EBV) infection and characterized by an extremely aggressive course and poor prognosis. We report a 46-year-old Caucasian woman who presented with multiple subcutaneous, painful nodules on the trunk first noticed a few weeks earlier. In addition to dermatological findings, the patient reported a 4-months history of necrotizing nasopharyngeal inflammation of unclear origin. Due to nonspecific histological and clinical findings mimicking a chronic inflammatory condition, a diagnosis of Wegener disease was made and immunosuppressive therapy with azathioprine was initiated. However the disease progressed under therapy. Histopathological reevaluation and immunophenotyping revealed a disseminated NK/T-cell lymphoma, nasal type. In the case of an unspecific chronic inflammatory process in the nasopharyngeal space one should always consider the possibility of this rare lymphoma, even in Europe.

Abstract
Primary natural killer/T-cell (NK/T-cell) lymphoma of the gastrointestinal tract is a very rare disease with a poor prognosis, and the duodenum is quite extraordinary as a primary lesion site. Here, we describe a unique case of a primary duodenal NK/T-cell lymphoma in a 26-year-old man who presented with abdominal pain and weight loss. Abdominal computed tomography scan demonstrated a hypodense tumor in the duodenum. Because of massive upper gastrointestinal tract bleeding during hospitalization, the patient was examined by emergency upper gastrointestinal endoscopy. Under endoscopy, an irregular ulcer with mucosal edema, destruction, necrosis, a hyperplastic nodule and active bleeding was observed on the duodenal posterior wall. Following endoscopic hemostasis, a biopsy was obtained for pathological evaluation. The lesion was subsequently confirmed to be a duodenal NK/T-cell lymphoma. The presenting symptoms of primary duodenal NK-/T-cell lymphoma in this patient were abdominal pain and gastrointestinal bleeding, and endoscopy was important for diagnosis. Despite aggressive treatments, the prognosis was very poor.

Abstract
T-cell lymphomas represent a heterogeneous group of neoplasms that encompass considerable clinical, morphologic, and immunophenotypic variation. The diagnosis of T-cell lymphoma is challenging because of its relative rarity, the lack of an immunophenotypic marker of clonality, and significant morphologic overlap with infectious/inflammatory processes and neoplasms, including Hodgkin and other non-Hodgkin lymphomas, and even mesenchymal or epithelial lesions. In the current World Health Organization classification of hematopoietic tumors, all except 1 subtype (ie, T-lymphoblastic lymphoma) are recognized as mature neoplasms derived from postthymic T cells. In addition to T-lymphoblastic lymphoma, this review will focus on nodal and extranodal T-cell lymphomas and exclude T-cell lymphomas presenting primarily in the skin. Extranodal natural-killer-cell/T-cell lymphoma, nasal type, will also be discussed because the derivation of this lymphoma from natural killer and natural killer-like T cells shows morphologic and immunophenotypic features that overlap with other T-cell lymphomas. In this review, we discuss the salient clinicopathologic, immunophenotypic, and genetic features, as well as our approaches to the diagnosis of lymphoblastic, nodal, and extranodal T-cell lymphomas.

Abstract
Epstein-Barr virus (EBV) is a ubiquitous γ-herpes virus that infects most people but results in life-threatening diseases in only a small subset. Persons who are unable to maintain the virus in its latent state can develop uncontrolled EBV-driven lymphoproliferative disorders and lymphomas. EBV-associated lymphomas are well characterized in patients with known defects in cellular immunity as occurs post-transplantation or HIV/AIDS but are increasingly recognized in patients without overt immunodeficiencies. Improved understanding of the biology of these lymphomas and the role EBV plays in lymphomagenesis offer the opportunity for improved therapies targeted at important signaling pathways and immunotherapy specific against EBV viral antigens.
