Abstract
Intravascular lymphomas are rare disease conditions that exhibit neoplastic lymphoid cells that are confined mainly to the lumens of small capillaries and medium-sized vessels. The majority of the intravascular lymphomas are of B-cell origin, but they can include NK/T-cell and CD30+ immunophenotypes. In the histologic differential diagnosis are benign proliferations such as intralymphatic histiocytosis and intravascular atypical CD30+ T-cell proliferation. In this review, we discuss the clinical, histopathologic, and molecular findings of intravascular B-cell lymphoma, intravascular NK/T-cell lymphoma, intralymphatic histiocytosis, and benign atypical intravascular CD30+ T-cell proliferation.

Abstract
The extranodal natural killer (NK) T-cell lymphoma of nasal type is a form of lymphoma that falls within the WHO/EORTC 2018 classification of cutaneous T-cell lymphomas. It is characterized for being aggressive, infrequent, and destroying midline facial structures; however, it can also be in primary or secondary form at extranasal sites, such as the skin or the gastrointestinal tract, among others. We report the case of an 18-year-old patient with an extranodal NK/T-cell lymphoma located in an extranasal site. The clinical presentation is characterized for being multifocal and with erythematous-violaceous plaques that progress to hemorrhagic blisters and necrotic ulcers. Although this type of lymphoma has been reported previously by others, the presence of blisters is an atypical finding, which we believe has been described only in one case in the medical literature.

Inhibition of extranodal NK/T-cell lymphoma by Chiauranib through an AIF-dependent pathway and its synergy with L-asparaginase. Cell Death Dis 2023; 14:316.

Abstract
Extranodal NK/T-cell lymphoma (NKTL) is a rare and aggressive form of extranodal lymphoma with a poor prognosis. Currently, there are very limited treatment options for patients with advanced-stage disease or those with relapsed/recurrent disease. Here we show that Chiauranib, an orally small molecule inhibitor of select serine-threonine kinases (aurora B, VEGFRs, PDGFR, CSF1R, c-Kit), inhibited NKTL cell proliferation, induced cell cycle arrest, as well as suppressed the microvessel density in vitro and in vivo similar as in other types of cancer cells. Surprisingly, Chiauranib unfolded a new effect to induce apoptosis of NKTL cells by triggering AIF-dependent apoptosis other than the traditional cyt-c/caspase mitochondrial apoptosis pathway. The knockdown of AIF in vitro and in vivo dramatically blocked the efficacy of Chiauranib on NKTL. Mechanistically, the release of AIF from mitochondria is due to the upregulation of VDAC1 by the AKT-GSK3β pathway and activation of calcium-dependent m-calpain, which promotes the cleavage of VDAC1 and therefore permits the release of AIF. Notably, the low expression of Bax in both NKTL cells and patient tissues restrained the cyt-c release. It resulted in the inhibition of cyt-c/caspase mitochondrial pathway, suggesting that drugs targeting this traditional pathway may not be effective in NKTL. Furthermore, we found that L-asparaginase triggered CD95 (Fas/Apo-1)-caspase 8-caspase 3 apoptotic pathway in NKTL cells, and combination of Chiauranib and L-asparaginase exhibited a synergistic effect, suggesting a feasibility to combine these two drugs for effective treatment of NKTL. This study demonstrates Chiauranib's positive efficacy toward NKTL through the activation of the AIF-dependent apoptosis pathway for the first time. The novel and multi-targets of Chiauranib and the synergistic effect with L-asparaginase may provide a promising therapy for NKTL patients.

Clin Med Insights Oncol 2023; 17:11795549231156692. [PMID: 36908718 PMCID: PMC9996724 DOI: 10.1177/11795549231156692] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Accepted: 01/26/2023] [Indexed: 03/11/2023] Open
Abstract
Background Extranodal NK/T-cell lymphoma, nasal type (ENKL), is an aggressive tumour with poor prognosis. Its early diagnosis may improve the prognosis of patients; however, it is often overlooked in many cases and misdiagnosed as an inflammatory sinus disease during its initial stage. Identifying the clinical characteristics of ENKL may aid otorhinolaryngologists in indicating cases early for a pathologic examination. In this study, we aimed to investigate the clinical characteristics of ENKL compared with that of diffuse large B-cell lymphoma (DLBCL), which is the most common nasal malignant lymphoma. Methods The backgrounds, clinical symptoms, blood test results, and computed tomography images of patients with nasal/paranasal malignant lymphoma in our hospital between 2012 and 2017 were investigated. The characteristics of ENKL and nasal DLBCL were compared to differentiate them. Results A total of 27 patients with nasal cavity and/or paranasal sinus lymphoma were included. Extranodal NK/T-cell lymphoma, nasal type, was diagnosed in 10 patients, while DLBCL was diagnosed in 17 patients. The median age of patients with ENKL was significantly lower than that of patients with DLBCL. All patients with ENKL had a unilateral lesion in the nasal cavity, with most located at the inferior turbinate. They also experienced nasal symptoms with significantly higher incidence of nasal obstruction and tendency of bleeding. Conclusion ENKL was often unilateral and caused nasal obstruction, unlike DLBCL. Those who are younger in age and have sinonasal tumour with unilateral nasal obstruction and bleeding should be considered for early and repeated biopsies at multiple sites, with ENKL taken into consideration.

Abstract
AIM To seek additional magnetic resonance imaging (MRI) features to improve the accuracy of differentiation between atypical sinonasal non-Hodgkin's lymphoma (NHL) and inverted papilloma (IP) using conventional MRI and apparent diffusion coefficient (ADC) maps. MATERIALS AND METHODS MRI examinations from 44 atypical cases (21 NHLs and 23 IPs) in sinonasal regions were reviewed retrospectively. Imaging features included tumour laterality, extension, T1-weighted imaging (WI)/T2WI signal intensity homogeneity and ratios, enhancement homogeneity and ratios, and ADCmean. RESULTS In cases of NHL, homogeneous signal intensity was often observed on T2WI, which was homogeneous and significantly less enhanced than the turbinate, with lower ADCmean. Whereas in IPs, heterogeneous signal intensity was seen on T2WI, which was heterogeneous and of comparable enhancement to the turbinate, and higher ADCmean values were commonly seen. An ADCmean cut-off point of 1.10 × 10-3 mm2/s achieved 100% sensitivity, 90% specificity, and 90% accuracy. In addition, special features were observed that support the distinction between the two tumours, including intestinal pattern enhancement in NHL and spot-like appearance on T2WI and enhancement in IP. CONCLUSIONS ADCmean was the most valuable metric for differentiating between the atypical sinonasal NHLs and IPs.

Abstract
Effectively treating vague symptoms in older adults can be challenging for clinicians. Many vague symptoms will resolve spontaneously with alleviating treatment. Two of the most alarming qualities of symptoms are duration and exacerbation. For primary care and family medicine physicians dealing with vague symptoms in older patients, identifying alarming symptoms and further investigating them can guide their decisions on advanced care directives. We experienced a case of a drastic clinical course of peripheral T-cell lymphoma in a 91-year-old man without specific symptoms or palpable lymphadenopathy on the surface of the body. Clinical observation and prompt pathological investigation were sufficient for diagnosis. However, the patient’s hope for home-based palliative care could not be achieved. For vague progressive symptoms in older patients, clinicians should consider the diagnostic process, including perspectives of palliative care, based on the needs of older patients.

Abstract
Natural killer T cell intravascular lymphoma is a rare category of lymphoma among older individuals. The presentation of natural killer T cell lymphoma varies, causing diagnostic challenges for clinicians. Thus far, only a few studies have reported this condition in the context of musculoskeletal symptoms. We encountered a case of natural killer T cell intravascular lymphoma in a patient who presented with symptoms of sternoclavicular arthritis and femoral pain. The initial diagnosis was undifferentiated hematologic malignancy because undifferentiated hematologic malignant cells were seen on the bone marrow biopsy. Further examination showed that the patient had a high fever and abnormal cells in the blood. Flow cytometry findings revealed the abnormal cells as CD16 and CD56 positive, leading to the diagnosis of natural killer T cell intravascular lymphoma. This is the first report indicating the possibility of natural killer T cell intravascular lymphoma as one of the differential diagnoses of acute joint and muscular pains among older patients and the importance of assessing multiple organs, including musculoskeletal organs, to diagnose intravascular lymphoma.

Abstract
Extranodal natural killer/T-cell lymphoma nasal type (NNKTL) is a type of non-Hodgkin's lymphoma that has been associated with Epstein–Barr virus (EBV). It has an aggressive behavior, known for predilection to metastasize to different organs. Central nervous system (CNS) spread from a primary location has been reported. Different modalities of treatment such as chemotherapy and radiation therapy have been employed in the management of this disease. Severe toxicities of currently available treatment have made clinicians seek more targeted therapies using molecular profiling. We present a 44-year-old Hispanic patient who was diagnosed with an early-stage NNKTL and treated with the modified SMILE regimen for 6 cycles. His EBV DNA PCR turned undetectable and remained so throughout the treatment. He sustained complete right vision loss due to right optic nerve invasion by the tumor, leading to prophylactic intravitreal methotrexate to the contralateral eye. The patient achieved good response with minimal residual disease. He was supposed to start radiation as a sequential therapy. However, the acute development of severe headache and confusion lead to a complete workup showing leptomeningeal spread. He eventually succumbed to the disease.

Abstract
Simple Summary In most Epstein–Barr virus (EBV)-infected individuals, the virus establishes a lifelong latent infection with no specific clinical manifestation. However, EBV primary infection and secondary reactivation may cause various EBV-associated lymphoproliferative disorders (LPD), including hematologic malignancies. Among them, EBV-positive T/NK LPD are uncommon diseases defined by the proliferation of T- or NK-cells infected by EBV, more commonly encountered in Asians and Latin Americans. They encompass a spectrum of disorders ranging from indolent reactive lesions to malignant and aggressive diseases. Despite novel insights from high-throughput molecular studies, the pathogenesis of these disorders is not well understood, and EBV-positive T/NK LPD diagnoses remain challenging due to their rarity and considerable overlap. Indeed, this article discusses new insights into EBV-positive T/NK LPD and focuses on diagnosis challenges, describing the difficulties to clarify the borders between overlapping LPD subtypes. Abstract Epstein–Barr virus (EBV) is a ubiquitous virus detected in up to 95% of the general population. Most people are asymptomatic, while some may develop a wide range of EBV-associated lymphoproliferative disorders (LPD). Among them, EBV-positive T/NK LPD are uncommon diseases defined by the proliferation of T- or NK-cells infected by EBV. The 2017 World Health Organization (WHO) classification recognizes the following entities characterized by different outcomes: chronic active EBV infection of T- or NK-cell types (cutaneous and systemic forms), systemic EBV-positive T-cell lymphoma of childhood, EBV-positive aggressive NK-cell leukemia, extra nodal NK/T-cell lymphoma nasal type, and the new provisional entity known as primary EBV-positive nodal T/NK-cell lymphoma. In addition, EBV associated-hemophagocytic lymphohistiocytosis is part of EBV-positive T/NK LPD, but has not been included in the WHO classification due to its reactive nature. Despite novel insights from high-throughput molecular studies, EBV-positive NK/T-cell LPD diagnoses remain challenging, especially because of their rarity and overlap. Until now, an accurate EBV-positive NK/T LPD diagnosis has been based on its clinical presentation and course correlated with its histological features. This review aims to summarize clinical, pathological and molecular features of EBV-positive T/NK LPD subtypes and to provide an overview of new understandings regarding these rare disorders.

Abstract
Extranodal NK/T-Cell Lymphoma, nasal type (ENKTL-NT) has some salient aspects. The lymphoma is commonly seen in Eastern Asia, has progressive necrotic lesions in the nasal cavity, makes midfacial destructive lesions, and shows poor prognosis. The lymphoma cell is originated from either NK- or γδ T-cells, which express CD56. Since the authors first demonstrated the existence of Epstein–Barr virus (EBV) DNA and EBV oncogenic proteins in lymphoma cells, ENKTL-NT has been recognized as an EBV-associated malignancy. Because the angiocentric and polymorphous lymphoma cells are mixed with inflammatory cells on a necrotic background, the diagnosis of ENKTL-NT requires CD56 immunostaining and EBER in situ hybridization. In addition, serum the EBV DNA level is useful for the diagnosis and monitoring of ENKTL-NT. Although ENKTL-NT is refractory lymphoma, the prognosis is improved by the development of therapies such as concomitant chemoradiotherapy. The basic research reveals that a wide variety of intracellular/cell surface molecules, cytokines, chemokines, and micro RNAs are involved in lymphomagenesis, and some of them are related to EBV. Understanding lymphoma behavior introduces new therapeutic strategies, such as the usage of immune checkpoint inhibitors, peptide vaccines, and molecular targeting therapy. This review addresses recent advances in basic and clinical aspects of ENKTL-NT, especially its relation to EBV features.

Abstract
RATIONALE Nasal-type, extranodal natural killer (NK)/T-cell lymphoma is a rare lymphoma. The tumor usually shows ulcerative and necrotic lesions in the nasal cavities and sinuses. Tissue involvement outside the nasal cavity is uncommon. PATIENT CONCERN We describe a 30-year-old man with a 2-month history of hoarseness, weight loss, and dyspnea. DIAGNOSIS Magnetic resonance image (MRI) showed edema of the larynx with obliteration of the airway. Laryngoscopic examination described necrotic tissue in the glottis and larynx. The biopsy showed chronic, necrotizing laryngitis, with no granulomas, vasculitis, or atypical cells. The immunologic and microbiologic study was negative. Later, after immunosuppressive therapy, the patient presented erythema and diffuse enlargement of the right arm. MRI showed myositis of the biceps and brachial muscles. Infection was rule out, and direct microscopy showed an extensive muscle infiltration by mononuclear cells and abundant mitosis. Immunohistochemistry was positive for CD3, CD8, Ki 67 (90%), and CD56 compatible with extranodal NK/T cell lymphoma. INTERVENTIONS The patient initially received immunosuppression treatments (corticoids, cyclofosfamide, and Rituximab) with relapsing episodes. When lymphoma was diagnosed, chemotherapy was started. OUTCOMES The patient died during chemotherapy. LESSONS Nasal-type, extranodal NK/T-cell lymphoma should be suspected even when there are no classical findings of neoplasms on histology. Immunohistochemistry is mandatory to rule it out.

Abstract
OBJECTIVE To assess clinical outcomes of newly diagnosed extranodal NK/T-cell lymphoma nasal-type (ENKTL) patients treated with L-asparaginase-containing chemotherapy as first-line chemotherapy. MATERIALS AND METHODS We retrospectively reviewed data of new ENKTL patients in Siriraj Hospital, Thailand during 2012-2016. RESULTS Among 27 patients, 16 were men and 11 were women, and their median age was 52 (range, 25-83) years. The primary sites were the aero-nasal area (23) and skin (4). Clinical stages of ENKTL were I, II, III and IV in 10, 8, 1 and 8 patients, respectively. Patients classified according to the NK cell-lymphoma prognostic index with PINK (27) and PINK-E (19) as low, intermediate, and high were 14, 8, 5, respectively and 11, 4, and 4, respectively. Chemotherapy regimens used were SMILE (24) and AspaMetDex (3). Fourteen patients received post- chemotherapy local radiation. The overall response rate for 26 assessable patients was 69%, with complete response in 14 patients (52%). Median progression-free and overall survival were 32 and 33 months, respectively. The most common L-asparaginase regimen related complications were hypofibrinogenemia (24) and hypersensitivity (9). The overall mortality at follow-up was 14/27 (52%) owing to sepsis (11) and disease progression (3). DISCUSSION L-asparaginase-based regimens showed similar results as other study results. including those in which hematopoietic stem cell transplantation was performed, suggesting that transplantation can be avoided if it is unaffordable. Thrombosis or bleeding, the regimen side effects, should be carefully monitored during treatment. CONCLUSIONS L-asparaginase-based regimens offer a good outcome as a front-line treatment for ENKTL.

Crit Rev Oncol Hematol 2021; 159:103237. [PMID: 33493634 DOI: 10.1016/j.critrevonc.2021.103237] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 06/09/2020] [Accepted: 01/16/2021] [Indexed: 02/07/2023] Open
Abstract
Extranodal NK/T-cell lymphoma, nasal type (ENKTCL-NT) is an aggressive malignancy associated with Epstein-Barr virus infection, with a geographic and racial predilection for some Asian and Latin American countries. ENKTCL-NT manifests as a necrotic process affecting nasal or upper aerodigestive structures and, rarely, extranasal sites such as skin, and the gastrointestinal tract. ENKTCL-NT was characterized by its poor prognosis irrespective of clinical stage and therapy. However, during the last two decades, advances in its clinicopathologic, genetic and molecular characterization have been achieved, as have changes in the chemotherapy regimens that, in combination with radiotherapy, are significantly improving the survival of these patients, especially in initial stages. For these reasons, we present an overview of the historical background of ENKTCL-NT along with an updated review of its potential etiological factors, clinicopathologic and molecular features, as well as its prognostic models, current treatment protocols, and future directions on potential promising therapeutic approaches.

Abstract
RATIONALE Primary extranodal natural killer (NK)/T-cell lymphoma (ENKTL) rarely occurs in childhood and adolescence. To the best of our knowledge, ENKTL of childhood in the gastrointestinal (GI) tract has not been reported yet. PATIENT CONCERNS A 12-year-old Chinese boy complained of abdominal pain and persistent fever for 1 month. DIAGNOSIS Grossly an ulcerated tumor with perforation was located at the proximal ascending colon, 5 cm × 4 cm × 1.5 cm in diameter. The tumor was poorly circumscribed, tan-white and solid. Histological evaluation revealed medium-sized atypical lymphoid cells with large areas of necrosis distributed throughout all layers of the colon. Small blood vessels with destroyed walls were surrounded by lymphoid cells. Immunohistochemistry (IHC) highlighted tumor cells as strongly positive for CD3, CD56, CD5, CD2, CD8, CD4, CD43, T-cell restricted intracellular antigen 1 (TIA-1) and granzyme B. The proliferation index, measured by Ki-67 expression was high with 60%. The In situ hybridization (ISH) for EBER was positive. TCR was negative. Therefore, the final diagnosis was ENKTL of childhood in the colon. INTERVENTIONS The patient underwent right hemicolectomy and ileocolostomy. OUTCOMES We recommended further evaluation and treatment, but the patient and patient family rejected further treatment of his condition. The patient died within 1 month after being discharged from hospital as a result of his disease. LESSONS ENKTL of childhood in the GI tract is extremely rare. Due to the non-specific clinical symptoms, it is easy it is easy not to think of this differential diagnosis at early stage. If patients have GI symptoms, ENKTL cannot easily be ignored. It is necessary to diagnose ENKTL of childhood in the GI tract by morphology and immunohistochemistry, and to differentiate from the GI T-cell lymphomas. We hope this case may serve as a reference improving clinical diagnosis and treatment.

Abstract
Purpose This retrospective study compared effectiveness between ≤4 cycles and ≥5 cycles of L-asparaginase/pegaspargase-based chemoradiation in newly diagnosed low-risk extranodal natural killer/T-cell lymphoma (ENKTL), nasal type classified according to the Prognostic Index of Natural Killer (PINK) lymphoma model. Patients and Methods Patients were categorized into ≤4-cycle (2–4 chemotherapy cycles, n = 166) and ≥5-cycle groups (5–6 cycles, n = 86). Propensity score matching analysis was used to reduce potential confounding bias between the two groups. Treatment responses, adverse events, and survival outcomes between the two groups were analyzed. Results No matter before or after matching (65 in the ≤4-cycle group, 65 in the ≥5-cycle group), response rates and survival outcomes were similar between the ≤4-cycle and ≥5-cycle groups. Incidences of grade 1–2 anemia and transaminase elevation were higher in the ≥5-cycle group. After matching, for stage IE disease, there were no differences in response rates and survival outcomes between the two groups. For stage IIE disease, the complete response rate was higher in the ≥5-cycle group (72.4% vs 92.6%, p = 0.049), and the 3-year overall survival (65.5% vs 85.2%, p = 0.024) and 3-year progression-free survival (58.6% vs 81.5%, p = 0.027) rates were significantly extended in the ≥5-cycle group. Conclusion When chemoradiotherapy strategies with L-asparaginase/pegaspargase-based regimens are applied to modern low-risk ENKTL patients classified according to the PINK model, it may be better to moderately extend chemotherapy courses in patients with stage IIE disease.

Abstract
OBJECTIVES Natural killer/T-cell lymphoma (NKTCL) is aggressive, and carries a poor prognosis worldwide. This retrospective study aimed to evaluate the clinical efficacy and safety of the LVD regimen (L-asparaginase, vincristine, and dexamethasone) combined with intensity-modulated radiation therapy (IMRT) for the treatment of early-stage nasal NKTCL in a Chinese population. METHODS The clinical data were collected from patients treated between March 2010 and January 2017. Patients received LVD chemotherapy combined with IMRT, and were followed for 30 to 90 months. All received radiotherapy at the end of the first/second cycle of chemotherapy. The survival curves were generated by the Kaplan-Meier method. RESULTS Among 94 patients who received 2 to 6 cycles (mean, 4 cycles) of treatments, 56 and 25 achieved complete and partial remission, respectively; 2 and 11 experienced stable disease and progressive disease. The overall objective response was 86.2%. Patients with elevated lactate dehydrogenase and skin invasion had a lower objective response rate. The progression-free survival rates at 1, 3, and 5 years were 90.3%, 73.5%, and 71.3%; the corresponding overall survival rates were 91.4%, 74.3%, and 74.3%. The main adverse events were myelosuppression (63.8% grades I to II, 12.8% grade III), gastrointestinal symptoms (63.8% grades I to II), hepatic lesion (55.3% grades I to II), hypoproteinemia (46.8% grades I to II), skin allergies (77.7% grades I to II, 3.2% grade III), and oral mucosal lesions (44.7% grades I to II, 33% grade III). No severe pancreatitis, anaphylaxis, or toxicity-related death was observed. CONCLUSION In patients with early-stage nasal NKTCL, our LVD-IMRT regimen produced excellent, durable therapeutic benefit in most patients, with acceptable toxicity and no acute mortality.

Abstract
Extranodal natural killer (NK)/T cell lymphoma (ENKTL) is a distinct subtype of Non-Hodgkin’s lymphoma mainly involving the nasal area. Since the entity was first recognized, treatment strategies have been evolving from anthracycline-based chemotherapy and radiotherapy to L-asparaginase containing regimens and recently immune checkpoint inhibitors. With the currently used combined chemotherapy and radiotherapy, more than 70% of patients with localized disease can be cured. L-asparaginase containing regimens have significantly improved treatment outcomes among patients with advanced disease. However, the treatment outcomes of patients with disease refractory to L-asparaginase containing regimens or who experience recurrence remain poor. In this article, we cover the current treatments for ENKTL and emerging treatment approaches.

Abstract
T-cell lymphomas are infrequently encountered in the head and neck area, with the most common subtype being Extranodal NK/T cell lymphoma, nasal type (ENKTL-NT). ENKTL-NT shows a predilection for midline facial structures presenting with ulcerative destructive lesions, whereas palatal involvement is one of the most prominent signs from the oral cavity. Herein, we describe a case of a 76-year-old Greek man with nasal obstruction and an extensive painful necrotic ulcer with ragged borders on the left distal portion of the soft palate and palatine tonsil of 4-months duration. After an initial non-diagnostic biopsy from the nasopharynx, a second incisional biopsy from the palatal lesions was performed. Histopathology was suggestive of an angiocentric lymphoproliferative neoplasm and immunohistochemical examination and in situ hybridization for EBV RNA led to a final diagnosis of ENKTL-NT. The patient was placed under combined chemotherapy and radiotherapy and no recurrence has been noted. Additionally, a retrospective review of the cases in the English literature with an established diagnosis of ENTKL-NT between 2000 and 2019, based on the latest WHO classification of Head and Neck tumors, is performed.

Abstract
Epstein-Barr virus (EBV)-positive T-cell and natural killer (NK)-cell lymphoproliferative diseases (EBV-TNKLPD) are a group of uncommon disorders characterised by EBV infection of T- and NK-cells. As a group, EBV-TNKLPD are more commonly encountered in Asians and Native Americans from Central and South America compared to Western populations. They encompass a spectrum of entities that range from non-neoplastic lesions such as EBV-associated haemophagocytic lymphohistiocytosis (EBV-HLH) to more chronic conditions with variable outcomes such as chronic active EBV infections (CAEBV) of T- and NK-cell type (cutaneous and systemic forms) and malignant diseases such as systemic EBV-positive T-cell lymphoma of childhood, aggressive NK-cell leukaemia, extranodal NK/T-cell lymphoma, nasal-type, and primary EBV-positive nodal T/NK-cell lymphoma. Due to their rarity, broad clinicopathological spectrum and significant morphological and immunophenotypic overlap, the diagnosis and precise classification of EBV-TNKLPD often pose a challenge to clinicians and pathologists. Correct classification of this group of rare diseases relies heavily on the age of onset, disease presentation, duration of symptoms and cell of origin (T- vs NK-cell lineage). In this review, we provide an update on the clinicopathological and molecular features of the various EBV-TNKLPD entities occurring in non-immunocompromised patients and present a practical algorithmic approach for the general pathologist who is confronted with these disorders in routine clinical practice.

Abstract
Purpose The objective of this study is to estimate radiotherapy (RT) modalities for patients with stage I-II nasal natural killer T-Cell lymphoma (NNKTCL), including plan quality, radiation delivery efficiency, cost of RT and excess absolute risk (EAR). Materials and methods Twenty-four representative patients with stage I-II NNKTCL treated with fix-field intensity-modulated radiotherapy (FF-IMRT) were re-planned for volumetric modulated arc therapy (VMAT), TomoDirect (TD) and TomoHelical (TH) on the TomoHDA system, respectively. Plan characteristics, cost of RT and EAR were compared. Results Compared with IMRT, TD and TH showed significant improvement in terms of D98%, D2%, cold spot volume and homogeneity index (HI) of planning target volume (PTV), while achieving worse Dmean and conformity index (CI). The mean dose of oropharynx, thyroid and left salivary, and the maximum dose of right salivary by TD (249.20%, p=0.000; 52.94%, p=0.000; 160.23%, p=0.022; 122.67%, p=0.027), VMAT (15.76%, p=0.000; 23.53%, p=0.000; 34.09%, p=0.000; 31.33%, p=0.000) and TH (250.32%, p=0.000; 58.82%, p=0.000; 120.45%, p=0.020; 117.33%, p=0.032) increased significantly compared to IMRT. VMAT reduced treatment time (p=0.000; 0.000; 0.000) and monitor units (MUs) (p=0.000; 0.000; 0.000) obviously compared with IMRT, TD and TH. The cost of RT for TD and TH increased 150% compared with IMRT and VMAT. IMRT obtained the lowest EAR to oropharynx, thyroid, left and right salivary gland in the four treatment modalities. Conclusion The results show that both TD and TH can achieve higher conformal target quality while getting worse organs at risk (OARs) sparing and EAR to some organs than IMRT for patients with stage I-II NNKTCL. IMRT delivers the lowest dose to most OARs, VMAT requires the lower cost of RT and shortest delivery time, and TH obtained the optimal target coverage. The results could provide direction for selecting proper RT modalities for different cases.

Abstract
OBJECTIVE Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) is an aggressive extranodal lymphoma of NK-cell or T-cell lineage. Its clinical features overlap with those of several sinonasal mass lesions. While the histopathological features are well described, diagnosis is often difficult, owing to presence of extensive coagulative necrosis, so that repeated biopsies may sometimes be necessary for correct diagnosis. Literature on cytological findings of ENKTL is limited. METHODS Cytomorphological features of cases of histologically confirmed ENKTL having corresponding cytology samples were reviewed retrospectively, to identify distinctive features that could possibly suggest this entity. RESULTS Aspirates from five patients were studied: four from cervical nodes, one from cheek swelling and one from pleural fluid. Two aspirates were reported as positive for malignancy, two as atypical lymphoid proliferation and one was non-diagnostic. Pleural fluid was reported as malignant, favouring a diagnosis of carcinoma. On cytology, aspirates showed medium to large cells with folded, indented nuclei and abundant pale cytoplasm, some with tongue-like cytoplasmic protrusions. A distinctive feature was presence of large loose clusters of tumour cells with arborising capillaries running through them. Interestingly, necrosis was consistently absent. Subsequent biopsies from palate (three cases) and nasal masses (two cases) confirmed the diagnosis of ENKTL. CONCLUSIONS Suspicion of ENKTL on cytology is crucial for timely diagnosis to avoid diagnostic delay, especially when only highly necrotic biopsy samples are available. Awareness of distinctive cytomorphological features is required to make fine needle aspiration an effective diagnostic tool for initial diagnosis and for evaluation of possible recurrences.

Abstract
OBJECTIVE Extra nodal natural killer/T-cell lymphoma (ENKTL), nasal type is a rare and highly aggressive type of non-Hodgkin's lymphoma (NHL) commonly presented in the nasal cavity or lymphatic system. However, the common causes of mortality in ENKTL remain unclear. We conducted a retrospective population-based cohort study to elucidate the different causes of mortality in ENKTL and illustrate the main causal and associated risk factors leading to death. METHODS The study included patients diagnosed with ENKTL from 1987 to 2014 in the Surveillance, Epidemiology, and End Results (SEER) program. Univariate survival analysis was conducted using Kaplan-Meier analysis, and multivariate analyses were performed using Cox proportional hazards regression model. Competing-risks regression model was applied to estimate specific risks associated with mortality. RESULTS The analysis demonstrated increased mortality in males and patients diagnosed at older age and higher disease stage. NHL was the most common cause of mortality in patients with ENKTL, accounting for 74.13% of deaths in the cohort, followed by other malignant cancers, heart diseases, and infection. However, NHL-specific death events were fewer in patients diagnosed with advanced disease stage compared with incidences of death by other causes such as disease of heart and infections. Significant difference was seen between patients diagnosed earlier than 2000, who showed a higher probability of dying from NHL, and those diagnosed later, who showed propensity to die from other malignant tumors and infection. No differences were found when comparing sex or age at diagnosis. CONCLUSION The most common cause of mortality in cases with ENKTL-NT is NHL. The female sex, diagnosis at young age and early stage are associated with improved prognosis. Further, the classification of Ann Arbor stage and year of diagnosis can provide references of specific causes of death, which might help decrease the mortality rate.

Abstract
Extranodal natural killer (NK-)/T cell lymphoma, nasal type (ENKL), 1 is a rare disease that often mimics rheumatological and infectious conditions and can therefore be difficult to diagnose. The authors present a case of a 55-year-old Vietnamese woman who was misdiagnosed with severe atrophic rhinitis and chronic sinus osteitis. Over a period of 8 months from initial referral, she underwent multiple biopsies and was treated with various antimicrobial regimens until the histopathological diagnosis of ENKL was finally made. Her presentation was complicated by bacterial dacrocystitis, preseptal cellulitis and a retrobulbar extraconal phlegmon requiring surgical drainage. She also subsequently developed a naso-oral fistula on treatment. This case highlights the importance of repeated biopsies, in particular from non-necrotic regions of the sinonasal tract when a patient does not respond to therapy and clinical suspicion of neoplastic pathology remains. This is the first case of ENKL to describe significant orbital complication.

Abstract
Objectives Extranodal NK/T-cell lymphoma is reportedly a rare but emerging type of
lymphoma in adolescents. The present study was performed to specify its
imaging characteristics. Methods Our hospital’s picture archiving and communication systems were searched from
January 2009 to December 2016. We identified 13 patients aged <18 years
with pathologically confirmed extranodal NK/T-cell lymphoma in the head and
neck region. The computed tomography and magnetic resonance images were
reviewed to summarize the imaging characteristics of extranodal NK/T-cell
lymphoma in adolescents. Results The mean age at onset was 15.2 ± 1.46 years (range, 12–17 years) with a
male:female ratio of 1.17:1.00. Most of the patients (n = 10) displayed
nasal cavity and/or paranasal involvement. The tumor was homogeneous in both
computed tomography and magnetic resonance images and showed slight
enhancement. No calcification or liquefactive necrosis was observed.
Adjacent structures were usually involved. Conclusion Suggestive imaging characteristics could acquaint specialists with extranodal
NK/T-cell lymphoma in adolescents, facilitating improved early recognition
of the diagnosis and helping to improve the patient’s outcome.

Abstract
Extranodal natural killer (NK)/T-cell lymphoma, nasal type (NNKTL) has very unique epidemiological, etiologic, histologic, and clinical characteristics. It is commonly observed in Eastern Asia, but quite rare in the United States and Europe. The progressive necrotic lesions mainly in the nasal cavity, poor prognosis caused by rapid local progression with distant metastases, and angiocentric and polymorphous lymphoreticular infiltrates are the main clinical and histologic features. Phenotypic and genotypic studies revealed that the lymphoma is originated from either NK- or γδ T-cell, both of which express CD56. In 1990, the authors first reported the presence of Epstein-Barr virus (EBV)-DNA and EBV-oncogenic proteins, and EBV has now been recognized to play an etiological role in NNKTL. in vitro studies revealed that a wide variety of cytokines, chemokines, and micro RNAs, which may be produced by EBV-oncogenic proteins in the lymphoma cells, play important roles for tumor progression in NNKTL, and could be therapeutic targets. In addition, it was revealed that the interaction between NNKTL cells and immune cells such as monocytes and macrophages in NNKTL tissues contribute to lymphoma progression. For diagnosis, monitoring the clinical course and predicting prognosis, the measurements of EBV-DNAs and EBV-micro RNAs in sera are very useful. For treatment with early stage, novel concomitant chemoradiotherapy such as DeVIC regimen with local radiotherapy and MPVIC-P regimen using intra-arterial infusion developed with concomitant radiotherapy and the prognosis became noticeably better. However, the prognosis of patients with advanced stage was still poor. Establishment of novel treatments such as the usage of immune checkpoint inhibitor or peptide vaccine with molecular targeting therapy will be necessary. This review addresses recent advances in the molecular understanding of NNKTL to establish novel treatments, in addition to the epidemiologic, clinical, pathological, and EBV features.

Abstract
Purpose To report a case of extranodal natural killer/T-cell lymphoma (ENKTCL), nasal type metastatic to the space beneath the retinal pigment epithelium (RPE) with coincident paraneoplastic lymphoma-associated retinopathy. Methods Findings of clinical and histopathologic examination are presented with differential diagnoses and a literature review. Case Report A 53-year-old man presented with bilateral blindness and had exudative retinal detachments overlying subretinal masses in both eyes. Flow cytometry of pericardial fluid revealed malignant T lymphocytes. After two cycles of chemotherapy, the patient was hospitalized and quickly expired. Autopsy revealed lymphoma involving the eyes, heart, right lung, and two subcarinal lymph nodes focally. Histopathologic examination of the eyes revealed intraocular metastases from ENKTCL, nasal type. Expression of CD3 and CD56, along with expression of Epstein-Barr virus by in situ hybridization, confirmed the diagnosis. Lymphomatous infiltrates were confined to the space beneath the neurosensory retina and between the RPE and the Bruch membrane, sparing the uveal tissue, similar to other metastatic T-cell lymphomas. Extensive RPE and photoreceptor loss in regions with and without underlying tumor was typical of a concurrent paraneoplastic lymphoma-associated retinopathy. Conclusion Patients diagnosed with ENKTCL should be evaluated by an ophthalmologist, as ophthalmic involvement portends a poor prognosis.

Abstract
BACKGROUND Extranodal NK/T cell lymphoma, nasal type (ENKTL-NT) is difficult to distinguish from nasal polyps and inverted papilloma, leading to its high misdiagnosis ratio. The aim of this study was to investigate its potential prognostic indicators. MATERIAL AND METHODS Kaplan-Meier method was used to calculate overall survival (OS) rate. Cox proportional hazards regression was used to analyze risk ratios (ORs) with 95% confidence intervals (CIs). RESULTS Nasal ala infiltration and nasal floor thickness >2.0 mm or nasal septum thickness >2.5 mm were potential prognostic factors for OS (p=0.0323 and 0.0072, respectively). Cox proportional-hazards regression indicated that high LMP1 expression and the nasal floor thickness >2.0 mm or nasal septum thickness >2.5 mm were the independent risk factors for poor OS of ENKTL-NT (HR=3.0655, p=0.028; HR=2.3650, p=0.0452, respectively). In the subgroup analysis, the OS rate was lower when the nasal floor thickness >2.0 mm or nasal septum thickness >2.5 mm in the patients who had high expression of LMP1 (p=0.0651), whereas high LMP1 expression increased the risk of worse prognostic outcome in patients with deep infiltration thickness. Thus, high LMP1 expression may contribute to the tissue invasion of ENKTL-NT. CONCLUSIONS Any patient with nasal ala soft-tissue invasion, nasal floor thickness >2.0 mm/nasal septum thickness >2.5 mm on CT imaging or high LMP1 expression should prompt immediate histopathologic diagnosis to rule out ENKTL-NT in clinical practice.

Abstract
BACKGROUND Primary intestinal NK/T cell lymphoma is rare but aggressive and exhibits a poor prognosis. Little is known about its clinical characteristics because few studies with small sample sizes have been reported. AIMS To provide clinicopathological features and endoscopic findings and to summarize the treatment outcomes of primary intestinal NK/T cell lymphoma to improve our understanding of this disease. METHODS Between January 2011 to December 2016, 13 patients with confirmed primary gastrointestinal NK/T cell lymphoma at our center were described, and an updated literature review was provided. RESULTS In this series of 13 cases, 69.23% were men, the median age was 39 years, and the median survival was 6 months. The common clinical manifestations included abdominal pain (76.92%) and gastrointestinal bleeding (46.15%). Lymphomas were common in the large intestine (69.23%). In 76.92% of patients, the clinical staging was stage I, and all 13 patients manifested ulcerative lesions and no tumor mass on endoscopy. The clinical characteristics of primary intestinal NK/T cell lymphomas were similar to results in existing literature. CONCLUSION Intestinal NK/T cell lymphoma shows nonspecific clinical features and poor prognosis, which is mainly expressed as ulcers on endoscopy. Emergency surgery may be an adverse prognostic factor of lymphoma, since it is prone to progress toward gastrointestinal perforation.

Abstract
Extranodal natural killer/T-cell lymphoma, nasal type (ENKL) is a subtype of mature T- and natural killer cell lymphomas characterized by its association with Epstein-Barr virus and extranodal involvement. Although there is geographic variance in the frequency of ENKL, its clinical features are similar between Western countries and endemic areas, such as East Asia. Anthracycline-containing chemotherapy is not recommended to treat ENKL. No standard treatment has been established based on the results of randomized controlled trials. In patients with localized disease, radiotherapy is a core component of the recommended first-line therapy. Radiotherapy administered at 50 to 54 Gy, extended involved-site radiotherapy considering tumor invasiveness, and the use of intensity modulated radiation therapy or volumetric modulated arc therapy are associated with efficacy of radiotherapy. Although the use of concurrent chemoradiotherapy has been supported by the results of clinical trials, accumulating evidence supports the use of sequential chemoradiotherapy with non-anthracycline-containing regimens that include l-asparaginase and/or platinum anticancer agents. l-asparaginase-containing chemotherapy is a key component of first-line treatments for systemic ENKL. Hematopoietic stem cell transplantation is recommended as a front-line consolidation therapy for newly diagnosed advanced-stage ENKL. Newer agents including immune checkpoint inhibitors are being investigated for treating ENKL. In this modern ENKL treatment era, multidisciplinary efforts are needed to identify the best timing and sequencing of radiotherapy, l-asparaginase, platinum, newer agents, and hematopoietic stem cell transplantation.

Abstract
OBJECTIVES To describe the epidemiology and analyze factors determinant of survival in patients with oropharyngeal lymphoma, using the Surveillance Epidemiology and End Results (SEER) database. METHODS 2504 patients with oropharyngeal lymphoma were identified using the most recent SEER database entry from 1976 to 2016. Demographic information, Ann Arbor stage, tumor histopathology and location were collected. Multivariate analysis was used to analyze patient and tumor characteristics associated with survival. RESULTS The mean age of the patients studied was 60.5years, 58.4% of the subjects were male and 81% were white. Diffuse large B cell lymphoma (DLBCL) was the most common histologic subtype involving 56.9% of cases. The most common subsite of origin was the tonsil, with 71% of lymphomas originating from there. The association of survival with stage, age, tumor location, presence of B symptoms, tumor pathology, gender and race was analyzed using multivariate regression. Decreased survival was significantly associated with patient age p<0.0001, Ann Arbor staging p=0.005, the presence of B symptoms p=0.003 and tumor histopathology (T cell tumors) p=0.01. Patients with tumors originating from the soft palate were significantly more likely to die asa result of their disease p=0.03. CONCLUSION Oropharyngeal lymphoma most commonly originates from the tonsil. DLBCL is the most common subtype and has a good prognosis. The presence of B symptoms, tumors originating from the soft palate and patients with T cell tumors have the worst prognosis. This information can potentially be of great utility to the head and neck surgeon discussing prognosis with patients suffering from oropharyngeal lymphoma.

Abstract
We compared the treatment outcomes, toxicities and prognoses of patients with stage IE-IIE extranodal natural killer/T-cell lymphoma (ENKTL) treated with intensity-modulated radiotherapy (IMRT) or three-dimensional conformal radiotherapy (3DCRT). Newly diagnosed early-stage ENKTL patients (N = 173) were enrolled and received extended involved-field radiotherapy following induction chemotherapy. Patients were treated with 3DCRT (n = 98) or IMRT (n = 75). One-to-one matching of the IMRT and 3DCRT groups was performed through propensity score matching, which yielded 23 pairs of patients. The two groups achieved similar complete remission rates before and after radiotherapy (P > 0.05). All patients were followed up for a median of 41 months. The rates of local recurrence-free survival (LRFS, P < 0.001), progression-free survival (PFS, P = 0.003) and overall survival (OS, P = 0.003) were longer in the IMRT than 3DCRT group. In the matched patients, IMRT was still associated with superior LRFS (P = 0.024), but not with improved PFS (P = 0.113) or OS (P = 0.115). Multivariate analysis also suggested IMRT was a favorable independent factor for LRFS (HR = 2.230, P = 0.043), but not for PFS (P = 0.195) or OS (P = 0.116). Equivalent acute toxicities were observed for 3DCRT and IMRT; however, among stage II patients who had received cervical irradiation, the rate of late xerostomia was lower in the IMRT than 3DCRT group (38.5% vs. 66.7%, P = 0.046). Overall, IMRT yielded a better treatment response and local control than 3DCRT, and tended to reduce late xerostomia in patients with cervical irradiation, but failed to enhance OS. Thus, IMRT is recommended for the treatment of stage IE-IIE ENKTL patients.

Abstract
Primary esophageal natural killer (NK)/T-cell lymphoma is a markedly rare tumor. There were only 6 cases of the disease identified prior to June 2015. In the present study, the aforementioned cases were validated, and relevant computed tomography (CT) results and clinical features of primary esophageal NK/T-cell lymphoma were determined, to increase awareness of this type of tumor. CT features and clinical presentations of a patient with pathologically confirmed esophageal NK/T-cell lymphoma was analyzed. The patient exhibited non-specific clinical symptoms and CT images revealed diffuse thickening of the entire length of the esophagus. The patient received cycles of systemic chemotherapy and subsequent chest CT images demonstrated prompt and marked shrinkage of the tumor. At the time of writing, the patient has survived for 24 months and experiences a good quality of life without postprandial fullness or difficulty swallowing solid food. In addition, the characteristics of 6 patients with complete clinical features of this type of tumor, on the basis of a review of published studies (online PubMed, Medline, Google Scholar, Chinese Biomedicine Database and China Journal Full Text Database search), were retrospectively analyzed. Although primary esophageal NK/T-cell lymphoma is a markedly rare tumor, it is considered to be included in differential diagnosis of patients presenting with a fungal or viral infection, therapy-related mucositis or reflux esophagitis. The final diagnosis of primary esophageal NK/T-cell lymphoma is on the basis of a combination of clinical, CT and histopathological results.

Dosimetric comparison of helical tomotherapy, VMAT, fixed-field IMRT and 3D-conformal radiotherapy for stage I-II nasal natural killer T-cell lymphoma. Radiat Oncol 2017; 12:76. [PMID: 28449713 PMCID: PMC5408431 DOI: 10.1186/s13014-017-0812-1] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2017] [Accepted: 04/25/2017] [Indexed: 01/15/2023] Open
Abstract
Background The aim of this study was to compare radiotherapy plans for Stage I-II nasal natural killer/T-cell lymphoma (NNKTL) using helical tomotherapy (HT), volumetric-modulated arc therapy (VMAT), Fixed-Field intensity-modulated radiotherapy (IMRT), and three-dimensional conformal radiotherapy (3D-CRT). Methods Eight patents with Stage I-II NNKTL treated with IMRT were re-planned for HT, VMAT (two full arcs), and 3D-CRT. The quality of target coverage, the exposure of normal tissue and the efficiency of radiation delivery were analyzed. Results HT showed significant improvement over IMRT in terms of D98%, cold spot volume and homogeneity index (HI) of planning target volume (PTV). VMAT provided best dose uniformity (p = 0.000) to PTV, while HT had best dose homogeneity among the four radiotherapy techniques (p = 0.000) to PTV. VMAT obviously reduced treatment time (p = 0.010; 0.000) compared to HT and IMRT. Mean dose of left and right optic nerve was significantly reduced by IMRT compared to HT (19.86%, p = 0.000; 21.40%, p = 0.002) and VMAT (8.97%, p = 0.002; 9.35%, p = 0.001), and maximum dose of left lens of VMAT increased over the HT (36.25%, p = 0.043) and IMRT (40.65%, p = 0.001). Conclusion The unexpected results show that both HT and VMAT can achieve higher conformal treatment plans while getting worse organs at risk (OARs) sparing than IMRT for patients with Stage I-II NNKTL. VMAT requires the shortest delivery time, and IMRT delivers the lowest dose to most OARs. The results could provide guidance for selecting proper radiation technologies for different cases.

Abstract
Objectives To describe the incidence and determinants of survival of patients with nasopharyngeal lymphoma (NPL) between 1973 and 2012 using the Surveillance, Epidemiology, and End Results (SEER) database. Study Design Retrospective cohort study using a national database. Methods The SEER registry was used to calculate survival trends for patients with NPL between 1973 and 2012. Patient data were then analyzed with respect to histopathology, age, sex, race, histologic subtype, Ann Arbor stage, and whether radiation therapy was given. Overall survival (OS) and disease-specific survival (DSS) were calculated. Results A total of 1119 cases of NPL were identified. The cohort was composed of 58.8% males. The mean age at diagnosis was 59.3 years. The median OS was 8.2 years. B-cell non-Hodgkin's lymphomas (NHLs) accounted for most cases (77.5%), with natural killer (NK)/T-cell lymphomas comprising 6.0% of cases. A total of 41.5% patients received radiation therapy. OS at 2, 5, and 10 years was 70%, 57%, and 45%, respectively. On multivariate analysis, advanced age and NK/T-cell NHL histologic subtype were associated with worse OS and DSS, while radiation therapy was associated with improved OS and DSS (all P < .05). Conclusion With the exception of NK/T-cell NHL subtypes, NPL is associated with a fair prognosis, with younger age, low Ann Arbor stage, and radiation therapy being independent positive prognosticators for survival.

Abstract
OBJECTIVE To compare the efficacy of radiotherapy (RT) plus chemotherapy (CMT) versus RT alone for early stage nasal natural killer (NK)/T-cell lymphoma. METHODS All the eligible studies were searched by PubMed, Medline, Embase and the Cochrane Library. The meta-analysis was performed to compare odds ratios (ORs) for overall survival (OS), disease-free survival (DFS) and progression-free survival (PFS). RESULTS Eight studies were included in the meta-analysis. Chemotherapy group did not significantly differ from RT group. The pooled OR and 95% confidence interval (CI) for 1-year, 3-year, 5-year and 10-year OS was 1.25 [0.84, 1.87], 1.10 [0.76, 1.58], 0.83 [0.59, 1.17] and 1.05 [0.70, 1.56]. In addition, the combined OR and 95% CI for 5-year DFS and PFS were 0.96 [0.53, 1.73] and 0.71 [0.45, 1.12]. CONCLUSIONS The current evidence suggests that CMT was not superior to RT alone. Radiotherapy may be still the main method in the treatment of early stage nasal NK/T-cell lymphoma.

Abstract
The nasal type of extranodal natural killer/T‐cell lymphoma is a rare aggressive lymphoma with poor prognosis. To discover a successful treatment, we investigated the efficacy and safety of chemotherapy with methotrexate, etoposide, dexamethasone, and polyethylene glycol‐asparaginase (MESA). Three cycles of MESA were administered to 46 patients with new or relapsed/refractory natural killer/T‐cell lymphoma. Complete response after 3 treatment cycles was 43.5%, the overall response rate was 87%, and 2‐year overall survival was 83.4%. Complete response was significantly better for newly diagnosed patients than for patients with relapsed/refractory disease. Patients with newly diagnosed disease had a significantly better overall response rate after 1, but not after 2 or 3 treatment cycles. Overall survival and progression‐free survival did not differ over 2 years. Grade 1/2 toxicities were frequent, but MESA was associated with fewer grade 3/4 events or treatment‐related deaths. These results will require confirmation in larger prospective trials.

Abstract
Nasal-type extranodal natural killer/T-cell lymphoma (ENKTL) is a rare disease presenting with non-specific symptoms, typically originating in the nasal cavity, palate, or midfacial region. Oral cavity is an extremely rare site for this type of lymphoma. In this report, we present a case of palatal perforation and oro-nasal fistula as a manifestation of recurrent ENKTL. Complicated disease entity should be considered when surgeons deal with palatal perforation and oro-nasal fistula.

Abstract
We report a rare case of extranodal NK/T-cell lymphoma, nasal type of the uterine cervix that showed cytologic features mimicking cervical cancer. A 65-year-old woman presented with vaginal bleeding. Gynecological examination revealed a bulky tumor of the cervix. A conventional Papanicolaou-stained cervical smear showed hypercellularity consisting of numerous variably sized cohesive clusters that mimicked epithelial tumors, with a necrotic and inflammatory background. A small number of individually scattered cells were also identified. These scattered cells showed pleomorphic, often cleaved, or horseshoe-shaped nuclei and pale cytoplasm. Biopsy specimens revealed a diffuse growth of atypical cells with an angiocentric pattern. Extensive necrosis and infiltration of inflammatory cells were present. There were numerous mitotic figures. The tumor cells were positive for CD45RO, CD3ε, CD56, granzyme B, TIA-1, CD7, and Epstein-Barr virus (EBV)-encoded small RNA (EBER) by in situ hybridization, and negative for cytokeratin, chromogranin A, synaptophysin, CD4, CD5, CD8, CD20, and CD30. Based on these findings, this tumor was diagnosed as extranodal NK/T-cell lymphoma, nasal type of the uterine cervix.

Abstract
PURPOSE To evaluate the effectiveness of concurrent chemoradiation therapy (CCRT) with 40 Gy followed by consolidation chemotherapy for localized extranodal natural killer (NK)/T-cell lymphoma (ENKTL), nasal type. METHODS AND MATERIALS From August 2004 to August 2012, 62 patients with newly diagnosed stage IE to IIE ENKTL underwent CCRT followed by consolidation chemotherapy. The median RT dose was 40 Gy. Cisplatin, 30 mg/m(2), was administered weekly during the RT course. Responders to CCRT were encouraged to undergo consolidation chemotherapy. Three different consolidation chemotherapy regimens were used consecutively: VIPD (etoposide, ifosfamide, cisplatin, and dexamethasone); VIDL (etoposide, ifosfamide, and dexamethasone followed by intramuscular injection of l-asparaginase); and MIDLE (methotrexate, etoposide, ifosfamide, mesna, and l-asparaginase). RESULTS The median follow-up period was 49 months (range 8-112). After completion of CCRT, 56 patients (90.3%) had a complete response, 4 (6.4%) had a partial response, 1 (1.6%) had stable disease, and 1 patient (1.6%) had progressive disease (PD). Consolidation chemotherapy was recommended to 61 patients, after excluding the patient with PD, but was actually delivered to 58. Of these 58 patients, 56 (96.5%) had a complete response and 2 (3.5%) had PD. During the follow-up period, 17 patients (including 3 with PD) experienced progression. The median interval to progression was 11 months (range 1-61). Local failure developed in 6 patients, of whom, 2 had developed progression outside the RT field. For all patients, the 3-year overall survival, progression-free survival, and local control rates were 83.1%, 77.1%, and 92.4%, respectively. Grade ≥3 nonhematologic toxicity developed in only 3 patients (4.8%). CONCLUSIONS Excellent clinical outcomes were achieved using CCRT with 40 Gy followed by consolidation chemotherapy. Additional investigation, however, is warranted to confirm our findings.

Abstract
ABSTRACT The history of radiation therapy in the treatment of malignancies is closely linked to its use in Hodgkin lymphoma. It was less than a decade after the first publication on x-rays that radiotherapy was used in the treatment of a Hodgkin lymphoma. Over time, radiotherapy has evolved with newer technology and better understanding of radiobiology. During this same time frame, the treatment of Hodgkin and non-Hodgkin lymphomas has also seen great progress. This review will provide detail on modern radiotherapy techniques, indications for utilization, and modern radiation field sizes and doses.

Abstract
BACKGROUND Previous studies have revealed conflicting findings concerning the efficacy of radiotherapy (RT) and radiochemotherapy (RCT) in IE/IIE extranodal nasal-type natural killer/T cell lymphoma (ENKTL). In this study, we conducted a comprehensive meta-analysis to address this issue. METHODS We systematically searched PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), EmBase, BISOS, Clinical Trials and some Chinese databases for relevant studies, and 2 prospective and 15 retrospective studies involving a total of 1595 patients met our inclusion criteria. RESULTS The meta-analysis showed no significant differences in complete remission (CR) [odds ratio (OR) 0.85, 95% confidence interval (CI) 0.42-1.72, p = 0.65], 5-year overall survival (OS) [hazard ratio (HR) 1.11, 95% CI 0.85-1.45, p = 0.43] and 5-year progression free survival (PFS) (HR 1.07, 95% CI 0.75-1.53, p = 0.70) in patients who received RT versus RCT. Furthermore, the addition of CT decreased neither systemic failure (SL) (OR 0.75, 95% CI 0.47-1.21, p = 0.24) nor locoregional failure (LF) (OR 1.17, 95% CI 0.68-2.01, p = 0. 57). CONCLUSIONS RCT did not have an obvious advantage over RT for treating IE/IIE ENKTL.
