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...

Extranodal natural killer (NK)/T-cell lymphomas are rare, highly aggressive tumors of the central nervous system (CNS) that commonly affect the nasal cavity or paranasal sinuses. NK/T-cell lymphomas are associated with a poor prognosis, as they exhibit a wide range of unique clinical presentations and neuroimaging findings that are currently difficult to detect. Pathological examination is considered to be more reliable for defining the pathological entity of NK/T-cell lymphoma. Early testing for fluorodeoxyglucose (FDG)-positron emission tomography combined with computed tomography may improve the evaluation of lymphomas, which have been known to display avid (18)FDG uptake...

Extranodal natural killer (NK)/T-cell lymphoma is an aggressive malignancy of putative NK-cell origin, with a minority deriving from the T-cell lineage. Pathologically, the malignancy occurs in two forms, extranodal NK/T-cell lymphoma, nasal type; and aggressive NK-cell leukaemia. Lymphoma occur most commonly (80%) in the nose and upper aerodigestive tract, less commonly (20%) in non-nasal areas (skin, gastrointestinal tract, testis, salivary gland), and rarely as disseminated disease with a leukemic phase...

To identify simple non-invasive prognostic factors for extranodal natural killer/T cell lymphoma (ENKTL), we have investigated the prognostic value of pretreatment β2-microglobin to lymphocytes ratio index (βLRI) or lactate dehydrogenase to lymphocytes ratio index (LLRI), by analyzing the retrospective data from 211 ENKTL patients. Receiver operating characteristic (ROC) curve analysis was performed to determine the cut-off value of pretreatment βLRI and LLRI. The univariate analysis indicated that Ann Arbor Stage (p = 0...

PURPOSE OF REVIEW: Here, we give an updated overview of the subtype distribution of lymphomas in East Asia and also present the genome sequencing data on two major subtypes of these tumors. RECENT FINDINGS: The distribution of lymphoma types/subtypes among East Asian countries is very similar, with a lower proportion of B-cell malignancies and a higher proportion of T/natural killer (NK)-cell lymphomas as compared to Western populations. Extranodal NK/T-cell lymphoma is more frequently observed in East Asia, whereas follicular lymphoma and chronic lymphocytic leukemia, are proportionally lower...

Nasal-type, extranodal NK/T cell lymphoma (ENKTCL) is a special type of lymphomas with geographic and racial specificity. Up to now, the standard first-line treatment is still not unified. In our previous report, the "sandwich" protocol produced good results. Continuing to use the "sandwich" mode, a new chemotherapy composed of L-asparaginase, cisplatin, etoposide and dexamethasone (LVDP) plus concurrent chemoradiotherapy (CCRT) was conducted in more patients with newly diagnosed, I/II stage ENKTCL. The results showed that 66 patients were enrolled...

Amanda M Termuhlen
Natural killer/T-cell (NK/T-cell) lymphomas are rare in children and adolescents and consist predominantly of nasal-type extranodal NK/T-cell lymphomas. More than half of pediatric/adolescent patients with NK/T-cell lymphomas present with localized nasal/sinus involvement, but the disease may involve many organs. NK/T-cell lymphoma cells are cytotoxic and associated with necrosis and angioinvasion; they express CD56, CD2, cytoplasmic CD3 epsilon, and to a variable degree CD30. The cells contain Epstein-Barr virus (EBV)-encoded RNA...

INTRODUCTION: Extranodal Natural Killer (NK)/T-cell lymphoma (NKTCL) nasal type is a rare but well-known disease with poor prognosis. NKTCL is more prevalent in Asia and comprises about 7-10% of all non-Hodgkin lymphoma cases in this region. The characteristic clinical pattern of NKTCL is the destruction of the midline structures of the mid-face. CASE REPORT: The present study examines a case of NKTCL in a 23-year-old man with a destructive ulcer of the palate and uvulae...

BACKGROUND: Extranodal natural killer T-cell lymphoma, nasal-type (NKTCL), is a rare malignancy in Western populations and is thus challenging for standardization of care and a prospective study. This study was aimed at defining patterns of care for NKTCL in the context of radiotherapy (RT) use and dose selection in the United States. METHODS: Six hundred forty-two stage I-II NKTCL patients from 1998 to 2012 were identified from the National Cancer Data Base. Binary logistic regression analyses were performed to identify sociodemographic, treatment, and tumor characteristics predictive of the treatment selection and RT dose...

Extranodal natural killer/T-cell lymphoma, nasal type (ENKL), is a rare subtype of non-Hodgkin lymphoma, and its treatment outcome was previously poor. Novel treatment strategies have improved the outcomes of ENKL remarkably in the last decade. Nowadays, patients with localized nasal ENKL are recommended treatment with concurrent chemoradiotherapy, and their 5-year overall survival rate is approximately 70%. In patients with advanced or relapsed/refractory disease, the efficacy of l-asparaginase-containing therapy has been confirmed...

Inhibition of the Janus kinase (JAK)-STAT pathway has been implicated as a treatment option for extranodal natural killer/T-cell lymphoma, nasal type (NTCL). However, JAK-STAT pathway alterations in NTCL are variable, and the efficacy of JAK-STAT pathway inhibition has been poorly evaluated. JAK3 mutation and STAT3 genetic alterations were investigated by direct sequencing and immunohistochemistry in 84 patients with newly diagnosed NTCL. Five of 71 patients with NTCL (7.0%) had JAK3 mutations in the pseudokinase domain: two JAK3(A573V), two JAK3(H583Y), and one JAK3(G589D) mutation...

Extranodal Natural Killer/T-cell lymphoma (ENKTL) is the most common cause of nasal cell lymphoma. It manifests by progressive destruction of the facial midline features with nasal obstruction and local destruction of soft tissue. Therefore, establishing the diagnosis of this disease tends to be difficult. This is attributed to an extensive differential diagnosis of infectious, autoimmune, neoplastic and inflammatory etiologies. We herein report the case of a 63-year-old female who presented to our department for persistent nasal congestion resistant to symptomatic treatment that was found to have an ENKTL...

RUNX3, runt-domain transcription factor, is a master regulator of gene expression in major developmental pathways. It acts as a tumor suppresser in many cancers but is oncogenic in certain tumors. We observed upregulation of RUNX3 mRNA and protein expression in nasal-type extranodal NK/T-cell lymphoma (NKTL) patient samples and NKTL cell lines compared to normal NK cells. RUNX3 silenced NKTL cells showed increased apoptosis and reduced cell proliferation. Potential binding sites for MYC were identified in the RUNX3 enhancer region...

Positron emission tomography-computed tomography (PET/CT) is widely used for initial staging and monitoring treatment responses in Hodgkin and diffuse large B-cell lymphoma. However, its prognostic value in extranodal natural killer (NK)/T-cell lymphoma (ENKL) remains unclear. Here, we conducted a retrospective study to determine the impact of PET/CT in ENKL. Fifty-two patients newly diagnosed with ENKL were enrolled. Baseline maximum standardized uptake values (SUVmax), whole-body metabolic tumor volume (WBMTV) and whole-body total lesion glycolysis (WBTLG) were recorded...
