Background: Current standard treatment, including non-anthracycline-based chemotherapy and optimal combining of radiotherapy, has dramatically improved outcomes of patients with extranodal natural killer/T-cell lymphoma (ENKTL) during the last decade. This study was conducted to investigate the clinical outcome of ENKTL patients with relapsed or progressive disease after initial current standard therapy. Patients and methods: We retrospectively reviewed patients diagnosed with ENKTL at six centers in four countries (China, France, Singapore, and South Korea) from 1997 to 2015 and analyzed 179 patients who had relapsed or progressed after initial current standard therapy...

Although nasal extranodal natural killer/T-cell lymphoma (nasal ENKL) shares some prognostic factors with other lymphomas, seldom studies had explored the prognostic value of hemoglobin. The ENKL cases in stage I-IV during 2000 to 2015 were collected from two medical centers (group A, n = 192), and were randomly divided into the group B (n = 155) and C (n = 37). Although the significant factors identified by the univariate analysis differed between the group A and B, the multivariate Cox regression indicated the same factors...

BACKGROUND: Extranodal NK/T-cell lymphoma (ENKTCL) reports from sub-Saharan Africa (SSA) are remarkably rare, despite early childhood acquisition and high prevalence of the causative infectious agent, Epstein-Barr virus (EBV), and frequent occurrence of other lymphoproliferative disorders causally associated with EBV. CASE PRESENTATIONS: At a national teaching hospital in Malawi, three patients of African descent were seen with ENKTCL between 2013 and 2014. Patients were aged between 29 and 60 years, two with craniofacial involvement and one with a primary abdominal tumor, and all were HIV-negative...

Extranodal natural killer (NK)/T-cell lymphoma, nasal type (ENKTCL) is a rare type of lymphoma that accounts for only 5%-18% of all cases of non-Hodgkin lymphoma (NHL). In published series, 60%-90% of NK/T-cell lymphomas are localized to the nasal and upper airway. We describe a 55-year man who presented with cough, sputum, dyspnea on exertion, and a chest computed tomography scan shows diffuse ground glass opacities (GGOs), suggestive of an interstitial lung disease. He was treated with a corticosteroid and his symptoms improved...

BACKGROUND: Extranodal natural killer/T-cell lymphoma (ENKTL) usually presents as a localized disease in the nasal cavity; extension to the male genitourinary system is very rare and has been characterized only recently. Most cases present with predominantly extranodal involvement, advanced stage disease, highly aggressive course, and strong association with Epstein-Barr virus (EBV). While metastasis is common in ENKTLs, the penis is rarely involved in both nasal and non-nasal ENKTLs and only one report was published to date...

Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) is a rare disease with a poor prognosis. The long-term effect of autologous hematopoietic stem cell transplantation (auto-HSCT) on ENKTL has been reported occasionally but needs further investigation. In this retrospective study from a single center, 20 ENKTL patients who received induction chemotherapy followed by auto-HSCT ± involved-field radiotherapy (IFRT) ± additional chemotherapy were enrolled as a study group. Another 60 fit ENKTL patients who received induction chemotherapy ± IFRT ± additional chemotherapy were selected as the control group...

Extranodal NK/T cell lymphoma (ENKL) is a rare entity, associated with an aggressive clinical behavior and poor prognosis. The optimal treatment strategies, particularly for relapsed patients, have not been clearly determined. A 40-year-old female ENKL patient with orbital involvement as the first presentation was initially suspected to have an orbital pseudotumor. When the patient developed disease progression following treatment with methylprednisolone, biopsy of the orbital mass was performed. Histopathological examination of the biopsy specimen was consistent with the diagnosis of ENKL (Ann Arbor stage IE)...

AIM: Nasal extranodal natural killer/T-cell lymphoma (nasal ENKTL), which is strongly associated with the Epstein-Barr virus infection, is a common disease in Asia and Latin America. We conducted a retrospective study to compare the overall survival (OS) following concurrent or sequential treatment with radiotherapy and chemotherapy in patients with early stage ENKTL. PATIENTS AND METHODS: The records of 58 cases from between 2000 to 2010 were retrieved. Of these, 28 patients (15 males, with median age of 51 years) were treated with sequential chemotherapy followed by radiotherapy (SCRT) and 30 patients (17 males, with median age of 46 years) were treated with concurrent chemoradiotherapy (CCRT)...

BACKGROUND: The prognostic significance of ABO blood type for lymphoma is largely unknown. We evaluated the prognostic role of ABO blood type in patients with extranodal natural killer (NK)/T-cell lymphoma (ENKTL). METHODS: We retrospectively analyzed clinical data of 697 patients with newly diagnosed ENKTL from three cancer centers. The prognostic value of ABO blood type was evaluated using Kaplan-Meier curves and Cox proportional hazard models. The prognostic values of the International Prognostic Index (IPI) and the Korean Prognostic Index (KPI) were also evaluated...

BACKGROUND: Extranodal natural killer/T-cell lymphoma (NKTCL), nasal type, is an aggressive malignancy with poor prognosis. Currently, there is no recommended standard therapy for relapsed NKTCL. CASE PRESENTATION: A 37-year-old woman with lymphadenopathy was diagnosed with NKTCL by biopsy of an enlarged lymph node on the right side of her neck. Enhanced computed tomography revealed no metastasis. For this patient, we performed continuous chemotherapy followed by radiotherapy; however, nodule biopsy showed metastases in her lower limbs 3 months after radiotherapy, which confirmed disease progression...

Extranodal natural killer (NK)/T-cell lymphoma, nasal type (ENKTL) is an extranodal aggressive T or NK-cell lymphoma that is characteristically associated with Epstein-Barr virus (EBV) infection and cytotoxic tissue-destructive features. Although ENKTL is described as a distinct entity according to the 2008 WHO classification, a considerable complexity is associated with the differential diagnosis of other T-cell lymphomas with respect to tumour cell origins, locations, and the presence of EBV infection, as well as molecular and cytogenetic abnormalities...

Extranodal natural killer (NK)/T cell lymphoma, nasal type (ENKTL) is an aggressive non-Hodgkin lymphoma and the majority of ENKTL cases are diagnosed at the localized stage. Radiotherapy in combination with chemotherapy has been used for localized ENKTL, but the optimal combination treatment modality and the best first-line chemotherapy regimen have not been defined. In this retrospective study, 44 patients with newly diagnosed, stages I/II ENKTL were enrolled and received intensity-modulated radiation therapy (IMRT, 50-56 Gy) followed by GDP (gemcitabine, dexamethasone, and cisplatin) chemotherapy...

The pathogenesis of Epstein-Barr virus-positive (EBV(+)) mature T-cell and natural killer (NK)-cell neoplasms is challenging to understand. The clinical features are diverse, with no typical manifestation. Therefore, it is important to analyze the association of the clinical characteristics and prognoses of patients with various factors associated with EBV(+) T/NK-cell neoplasms, particularly extranodal NK/T cell lymphoma, systemic EBV(+) T/NK cell lymphoproliferative disorders, aggressive NK cell leukemia and EBV(+) peripheral T-cell lymphoma...

Extranodal natural killer/T-cell lymphoma (ENKTCL) is a rare form of non-Hodgkin lymphoma. This neoplasm is more prevalent in regions of Asia and Latin America and most commonly involves the sinonasal tract, presenting with signs of nasal obstruction, epistaxis, or sinus infection. It is a locally destructive and angioinvasive neoplasm. The treatment of ENKTCL is dependent on the extent of the tumor. For localized disease, the treatment is chemoradiation. For disseminated disease, treatment is mainly chemotherapy-based...

Epstein-Barr virus (human herpesvirus-4) is very common virus that can be detected in more than 95% of the human population. Most people are asymptomatic and live their entire lives in a chronically infected state (IgG positive). However, in some populations, the Epstein-Barr virus (EBV) has been involved in the occurrence of a wide range of B-cell lymphoproliferative disorders (LPDs), including Burkitt lymphoma, classic Hodgkin's lymphoma, and immune-deficiency associated LPDs (post-transplant and human immunodeficiency virus-associated LPDs)...

Objective: Great heterogeneity exists in clinical behavior and survival outcome in patients with stage IE/IIE extranodal natural killer/T-cell lymphoma, nasal type (ENKTL). In this study, we proposed lymphocyte/monocyte ratio (LMR) as a new prognostic factor for these early stage ENKTL. Methods: We retrospectively examined the LMR as a prognostic variable in a cohort of 379 patients with newly diagnosed stage IE/IIE ENKTL. The relationship between the LMR and clinicopathologic variables were analyzed in Kaplan-Meier log-rank survival analysis, and the Cox proportional hazards model was used to determine the survival significance of the LMR for both progression-free survival (PFS) and overall survival (OS)...

BACKGROUND: Mature T-cell and natural killer (NK)-cell lymphomas compose a heterogeneous group of non-Hodgkin lymphomas, and extranodal NK/T-cell lymphoma, nasal type (ENKTL) is an aggressive subtype with sporadic CD30 expression. However, the significance of CD30 expression in ENKTL is controversial. We aimed to classify a large cohort of patients with mature T-cell and NK-cell lymphomas according to the 2016 World Health Organization (WHO) classification guidelines and to study the association between CD30 expression and prognosis of patients with ENKTL...
