Background:Nasal-type extranodal natural killer/T-cell lymphoma(ENKTCL) originates primarily in the nasal cavity or extra-nasal sites within the upper aerodigestive tract.However,it is unclear whether the primary site can serve as an independent prognostic factor or whether the varying clinical outcomes observed with different primary sites can be attributed merely to their propensities of regional lymph node involvement.The aim of this study was to investigate the prognostic implications of the primary site and regional lymph node involvement in patients with early-stage nasal-type ENKTCL.Methods:To develop a nomogram,we reviewed the clinical data of 215 consecutively diagnosed patients with early-stage nasal-type ENKTCL who were treated in Sun Yat-sen University Cancer Center with chemotherapy and radiotherapy between 2000 and 2011.The predictive accuracy and discriminative ability of the nomogram were determined using a concordance index(C-index) and calibration curve.Results:The 5-year overall survival(OS) and progression-free survival(PFS) rates of patients with nasal ENKTCL were higher than those of patients with extra-nasal ENKTCL(OS:68.2%vs.46.0%,P = 0.030;PFS:53.4%vs.26.6%,P = 0.010).The 5-year OS and PFS rates of patients with Ann Arbor stage IE ENKTCL were higher than those of patients with Ann Arbor stage HE ENKTCL(OS:66.3%vs.59.2%,P = 0.003;PFS:51.4%vs.40.3%,P = 0.009).Multivariate analysis showed that age >60 years,ECOG performance status score >2,elevated lactate dehydrogenase(LDH) level,extranasal primary site,and regional lymph node involvement were significantly associated with lower 5-year OS rate;age >60 years,elevated LDH level,extra-nasal primary site,and regional lymph node involvement were significantly associated with lower 5-year PFS rate.The nomogram included the primary site and regional lymph node involvement based on multivariate analysis.The calibration curve showed good agreement between the predicted and actual 5-year OS and PFS rates,and the C-indexes of the nomogram for the OS and PFS rates were 0.697 and 0.634,respectively.Conclusions:The primary site and regional lymph node involvement are independent prognostic factors for earlystage ENKTCL treated with chemotherapy followed by definitive radiotherapy. 展开更多

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.Methods:We selected consecutive patients with mature T-cell and NK-cell lymphomas who attended our institution between September 1,2009 and August 31,2013.We classified the lymphomas according to the 2016 revision of the WHO classification of lymphoid neoplasms,analyzed the associations between CD30 expression and clinicopathologic features of ENKTL patients,and evaluated the prognostic implications of CD30 expression.Results:We identified 622 consecutive patients with mature T-cell and NK-cell lymphomas,including 317(51.0%)patients with ENKTL.In addition,CD30 expression was detected in 43(47.3%) of a subset of 91 patients with ENKTL.No clinicopathologic features were associated with CD30 expression,and CD30 positivity showed no prognostic significance in patients with ENKTL.Conclusions:ENKTL is the most common type of mature T-cell and NK-cell lymphoma diagnosed at our institution.CD30 is frequently expressed in ENKTL and represents a therapeutic target;however,it may not be a prognostic marker. 展开更多

Objective:To compare the efficacy and safety of the novel SVILE regimen with the P-GemOx regimen in patients with newly diagnosed extranodal natural killer/T-cell lymphoma,nasal type(ND-ENKTL).Methods:From April 2015 to July 2018,103 patients with ND-ENKTL were randomly assigned to SVILE(experimental group)or P-GemOx(control group)chemotherapy followed by radiotherapy and consolidation chemotherapy.The primary endpoint was the overall response rate after 3 cycles of chemotherapy,and secondary study endpoints were complete response(CR),progression-free survival(PFS),and overall survival(OS).Safety was also evaluated.Results:There were no significant differences in baseline characteristics in the experimentalvs.control groups.In experimental and control groups,respectively,the overall response rates were 91.7%vs.97.0%for stageI/II and 75.0%vs.72.2%for stage III/IV.The CR rates were 83.4%vs.97.0%for stage I/II and 68.8%vs.61.1%for stage III/IV.None of those differences were significant.There was no significant difference in PFS and OS between groups and between patients in stage I/II and stage III/IV.The 3-year PFS and OS in stage I/II were 88.3%vs.93.3%and 88.8%vs.97.0%,respectively.The 3-year PFS and OS in stage III/IV were 46.2%vs.65.7%and 68.8%vs.72.2%,respectively.The common adverse events were hematological toxicity,hepatotoxicity,and coagulation abnormalities,which were found to be reversible with supportive therapy.Conclusions:The novel SVILE regimen has comparable effects to those of P-GemOx in patients with ND-ENKTL and is well tolerated.SVILE is a therapeutic option for ND-ENKTL. 展开更多

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.Results:Compared with patients with blood type O,those with blood type non-O tended to display elevated baseline serum C-reactive protein levels(P=0.038),lower rate of complete remission(P=0.005),shorter progression-free survival(PFS,P<0.001),and shorter overall survival(OS,P=0.001).Patients with blood type O/AB had longer PFS(P<0.001) and OS(P=0.001) compared with those with blood type A/B.Multivariate analysis demonstrated that age >60 years(P<0.001),mass ≥5 cm(P=0.001),stage Ⅲ/Ⅳ(P<0.001),elevated serum lactate dehydrogenase(LDH) levels(P=0.001),and blood type non-O were independent adverse predictors of OS(P=0.001).ABO blood type was found to be superior to both the IPI in discriminating patients with different outcomes in the IPI low-risk group and the KPI in distinguishing between the intermediate-to-low-and high-to-intermediate-risk groups.Conclusions:ABO blood type was an independent predictor of clinical outcome for patients with ENKTL. 展开更多

BACKGROUND Extranodal natural killer(NK) T-cell lymphoma(ENKTL), nasal type is a rare subtype of extranodal non-Hodgkin lymphoma characterized by vascular damage and necrosis. The lesions usually present in the nasal cavity and adjacent tissues, however, the disease originates from the gastrointestinal or genitourinary tract in 25% of cases. Since rectal involvement in ENKTL is rare, rectal symptoms in the course of ENKTL are often misdiagnosed and considered to be related to benign diseases such as rectal fistula or perianal abscess.CASE SUMMARY We report the case of a 24-year-old Han Chinese female who initially presented with a perianal abscess that was subsequently diagnosed as nasal type ENKTL.Due to typical perianal pain, perianal abscess was diagnosed and surgical incision and drainage were performed. After recurrent, severe anal hemorrhages leading to hypovolemic shock and multiple surgeries, a diagnosis of ENKTL was made. The patient's condition gradually deteriorated, and she died shortly after initiation of chemotherapy.CONCLUSION Systemic and neoplastic diseases should be included in the differential diagnosis of any potentially benign perianal abscess complicated with recurrent hemorrhages. 展开更多

BACKGROUND Natural killer(NK)/T cell lymphoma is a rare and highly aggressive malignant tumor,and is a special form of non-Hodgkin's lymphoma.Although extranodal involvement is frequently found in tissues such as the skin,testicular and gastrointestinal tract etc,its presence in skeletal muscle has scarcely been reported in the literature.CASE SUMMARY We report a case of extranodal NK/T cell lymphoma with muscle swelling as the first clinical manifestation.A 42-year-old man,who initially presented with localized swelling in the double lower extremities,demonstrated gradual facial and eyelid swelling,and his imaging results showed multiple sites of muscle damage throughout the body.The final pathological results suggested NK/T cell lymphoma,and immunohistochemistry showed CD20(-),CD3(+),CD30(+),CD56(-),EBER(+),Ki67(60%),TIA-1(+)and CD68(±)staining.The muscle swelling significantly improved after treatment with chemotherapy regimens.CONCLUSION This disease is difficult to diagnose and highly invasive,and should be included in the differential diagnosis of unexplained muscle swelling. 展开更多

Objective This study aimed to explore the combined prognostic value of pretreatment neutrophil-tolymphocyte ratio(NLR), lymphocyte-to-monocyte ratio(LMR), and platelet-to-lymphocyte ratio(PLR) in newly diagnosed IE/IIE extranodal natural killer/T-cell lymphoma(ENKTL) treated with a P-Gemox regimen combined with radiotherapy or radiotherapy alone.Methods A total of 132 patients from 2009 to 2017 at the Sichuan Cancer Hospital were enrolled in the study. The cutoff values of NLR, LMR, and PLR using overall survival(OS) rate as an endpoint were obtained by the receiver operating curve. Results The cutoff value of NLR was 3.5. Patients with high NLR had significantly shorter progressionfree survival(PFS)(P < 0.001) and OS(P < 0.001) than those with low NLR. Similarly, the cutoff value of LMR was 3.0. The high LMR group had significantly longer PFS(P=0.001) and OS(P < 0.001) than the low LMR group. Similarly, the cutoff value of PLR was 191.7. The high PLR group was significantly associated with poor PFS(P < 0.001) and OS(P < 0.001) than the low PLR group. Furthermore, combining NLR, LMR, and PLR to build a new model to stratify patients into low-, intermediate-, intermediate-high-, and high-risk groups, there were also significant differences in PFS(P < 0.001) and OS(P < 0.001). The univariate analysis showed that presenting B symptoms, stage IIE, local tumor invasion, Eastern Cooperative Oncology Group score ≥ 2, elevated lactate dehydrogenase level, elevated NLR, decreased LMR, and elevated PLR were significantly associated with poor survival. The multivariate analysis demonstrated that PLR was an independent prognostic factor for both PFS(hazard ratio [HR]= 2.073, 95% confidence interval [CI]= 1.080–3.981, P = 0.028) and OS(HR = 2.127, 95% CI = 1.102–4.107, P = 0.025).Conclusion Elevated pretreatment PLR was a novel simple predictor of poor survival in patients with stage IE/IIE ENKTL. Combining NLR, LMR, and PLR could provide additional stratification. 展开更多

BACKGROUND Primary intestinal extranodal natural killer/T-cell lymphoma,nasal type(PIENKTCL)is a rare non-Hodgkin’s lymphoma(NHL)subtype,and its prognosis is extremely poor.Clinical characteristics of the disease are not obvious and easily misdiagnosed.In this case report,we describe a patient with PI-ENKTCL who presented with intermittent hematochezia.The advantages of positron emission tomography/computed tomography(PET-CT)as a useful diagnostic tool and the role of surgery as an important therapy are highlighted.CASE SUMMARY A 45-year-old man,hospitalized due to intermittent hematochezia,underwent gastroscopy,colonoscopy,biopsy and CT,but no cause was found.Hence,we carried out a multidisciplinary team(MDT)discussion on the causes and treatment of this patient,and it was decided to perform PET-CT imaging with a MDT discussion of the results.PET-CT demonstrated a diagnosis of lymphoma and it was decided to surgically resect the lesion,and a R0 resection was successfully performed.Postoperative pathology showed negative resection margins,and examination of the lesion confirmed the diagnosis of PI-ENKTCL.After surgery,the patient underwent a follow-up period of 6 mo and received 6 cycles of gemcitabine,oxaliplatin and L-asparaginase.No recurrence or metastasis occurred.CONCLUSION PI-ENKTCL is rare,and MDT discussion is required during diagnosis.PET-CT can be performed for imaging diagnosis.Treatment is based on surgical resection,and the best treatment regimen is determined according to postoperative pathological results to improve prognosis and to extend survival in patients. 展开更多

Natural killer/T-cell lymphoma(NKTCL)is a highly invasive subtype of non-Hodgkin lymphoma,typically positive for cytoplasmic CD3,CD56,cytotoxic markers,including granzyme B and TIA1,and Epstein-Barr virus(EBV).The current treatment methods for NKTCL are associated with several drawbacks.For example,chemotherapy can lead to drug resistance,while treatment with radiotherapy alone is inadequate and results in frequent relapses.Moreover,hematopoietic stem cell transplantation exhibits limited efficacy and is not well recognized by domestic and foreign experts.In recent years,immunotherapy has shown good clinical results and has become a hot spot in cancer research.Clinical activity of targeted antibodies,such as daratumumab(anti-CD38 antibody)and brentuximab vedotin(anti-CD30 antibody),have been reported in NKTCL.Additionally,dacetuzumab and Campath-1 H have demonstrated promising results.Further encouraging data have been obtained using checkpoint inhibitors.The success of these immunotherapy agents is attributed to high expression levels of programmed death-ligand 1 in NKTCL.Furthermore,anti-CCR4 monoclonal antibodies(m Abs)exert cytotoxic actions on both CCR4+tumor cells and regulatory T cells.Depletion of these cells and the long half-life of anti-CCR4 m Abs result in enhanced induction of antitumor effector T cells.The role of IL10 in NKTCL has also been investigated.It has been proposed that exploitation of this cytokine might provide potential novel therapeutic strategies.Cellular immunotherapy with engineered cytotoxic T lymphocytes targeted against LMP1 and LMP2 has shown promising results and sustained remission.Cellular immunotherapy may be used either as maintenance therapy following initial induction chemotherapy or in cases of relapsed/refractory disease.The present review outlines the known immunotherapy targets for the treatment of NKTCL. 展开更多

We report a case of natural killer(NK)/T-cell lymphoma with concomitant syndrome of inappropriate antidiuretic hormone secretion(SIADH).The patient was a 64-yearold woman with a history of nasopharyngeal carcinoma of over 30 years.She was admitted with a chief complaint of intermittent fever for 2 mo.Palpation after admission indicated a swollen lymph node below the left jaw.Multiple imaging examinations on admission indicated multiple enlarged lymph nodes throughout the body.We performed a left submandibular lymph node biopsy,and the results revealed NK/T-cell lymphoma.A biochemical examination indicated Epstein-Barr virus positivity.At the same time,the patient developed hyponatremia.Based on her laboratory examination and clinical manifestation,decreased plasma osmolality,urine osmolality greater than plasma osmolality,lack of skin swelling,normal blood pressure,normal renal function,no adrenal function detected on serology,and no abnormalities in imaging examination of the adrenal glands,the likelihood of SIADH in the patient was high.After fluid restriction and administration of sodium chloride,the patient’s blood sodium level gradually increased.Subsequently,the immune function of the patient declined,there were severe symptoms of infection,and she died of respiratory failure.NK/T-cell lymphoma associated with SIADH has not,to our knowledge,been previously reported in PubMed.This case emphasizes the importance of monitoring serum ion levels,especially serum sodium,in patients with NK/T-cell lymphoma. 展开更多

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 painand 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. 展开更多
