ABSTRACT
Objective: To analyze the clinical presentation and progression risk factors of patients with monoclonal gammopathy of undetermined significance (MGUS) in China. Methods: We retrospectively assessed the clinical features and disease progression of 1 037 patients with monoclonal gammopathy of undetermined significance between January 2004 and January 2022 at Peking Union Medical College Hospital. Results: A total of 1 037 patients were recruited in the study, including 636 males (63.6%) , with a median age of 58 (18-94) years. The median concentration of serum monoclonal protein was 2.7 (0-29.4) g/L. The monoclonal immunoglobulin type was IgG in 380 patients (59.7%) , IgA in 143 patients (22.5%) , IgM in 103 patients (16.2%) , IgD in 4 patients (0.6%) , and light chain in 6 patients (0.9%) . 171 patients (31.9%) had an abnormal serum-free light chain ratio (sFLCr) . According to the Mayo Clinic model for risk of progression, the proportion of patients in the low-risk, medium-low-risk, medium-high risk, and high-risk groups were 254 (59.5%) , 126 (29.5%) , 43 (10.1%) , and 4 (0.9%) , respectively. With a median follow-up of 47 (1-204) months, 34 of 795 patients (4.3%) had disease progression, and 22 (2.8%) died. The overall progression rate was 1.06 (0.99-1.13) /100 person-years. Patients with non-IgM MGUS have a markedly higher disease progression rate per 100 person-years than IgM-MGUS (2.87/100 person-years vs 0.99/100 person-years, P=0.002) . The disease progression rate per 100 person-years in non-IgM-MGUS patients of Mayo classification low-risk, medium-low risk and medium-high risk groups were 0.32 (0.25-0.39) /100 person-years, 1.82 (1.55-2.09) /100 person-years, and2.71 (1.93-3.49) /100 person-years, which had statistically difference (P=0.005) . Conclusion: In comparison to non-IgM-MGUS, IgM-MGUS has a greater risk of disease progression. The Mayo Clinic progression risk model applies to non-IgM-MGUS patients in China.

Objective: To investigate the causative factors of renal function in newly diagnosed multiple myeloma (MM) patients with renal inadequacy. Methods: 181 MM patients with renal impairment from August 2007 to October 2021 at Peking Union Medical College Hospital were recruited, whose baseline chronic kidney disease (CKD) stage was 3-5. Statistical analysis was performed based on laboratory tests, treatment regimens, hematological responses, and survival among various renal function efficacy groups. A logistic regression model was employed in multivariate analysis. Results: A total of 181 patients were recruited, and 277 patients with CKD stages 1-2 were chosen as controls. The majority choose the BCD and VRD regimens. The progression-free survival (PFS) (14.0 months vs 24.8 months, P<0.001) and overall survival (OS) (49.2 months vs 79.7 months, P<0.001) of patients with renal impairment was considerably shorter. Hypercalcemia (P=0.013, OR=5.654) , 1q21 amplification (P=0.018, OR=2.876) , and hematological response over a partial response (P=0.001, OR=4.999) were independent predictive factors for renal function response. After treatment, those with improvement in renal function had a longer PFS than those without (15.6 months vs 10.2 months, P=0.074) , but there was no disparity in OS (56.5 months vs 47.3 months, P=0.665) . Conclusion: Hypercalcemia, 1q21 amplification, and hematologic response were independent predictors of the response of renal function in NDMM patients with renal impairment. MM patients with CKD 3-5 at baseline still have worse survival. Improvement in renal function after treatment is attributed to the improvement in PFS.

OBJECTIVE@#To explore the regulatory effect of chidamide on CD8+ T cells in T-cell acute lymphoblastic leukemia.@*METHODS@#The expression levels of CXCL9 and CXCL3 mRNA in Jurkat cells, lymphocytes treated with chidamide and lymphocytes co-cultured with chidamide-treated Jurkat cells were detected by fluorescence quantitative PCR. The proportion of CD8+ T cells in lymphocytes treated with chidamide and lymphocytes co-cultured with chidamide-treated Jurkat cells was determined by flow cytometry.@*RESULTS@#Chidamide upregulated CXCL9 mRNA expression in Jurkat cell line in a dose-dependent manner (r=0.950). The mRNA expression of CXCL9 in chidamide 5 μmol/L group was 164 times higher than that in control group. Chidamide upregulated CXCL9 mRNA expression in lymphocytes, but the up-regulated level was significantly lower than that in Jurkat cell line treated with the same concentration of chidamide. Co-culture with chidamide treated Jurkat cells upregulated the proportion of CD8+ T cells in lymphocytes.@*CONCLUSION@#In T-cell acute lymphoblastic leukemia, chidamide may increase the concentration of CXCL9 in the tumor microenvironment by up-regulating the expression of CXCL9 in tumor cells, leading to an increase in the number of CD8+ T cells.

Objective: To evaluate the clinical characteristics, treatment response, and outcomes in patients with classical hairy cell leukemia (cHCL) and HCL variant (HCL-V). Methods: This is a retrospective case series study. Between January 2011 and December 2021, clinical data of 30 patients newly with diagnosed HCL at Peking Union Medical College Hospital were analyzed. The main outcome measures include clinical characteristics, treatment efficacy and survival. The Kaplan-Meier method was used for survival analysis. Results: Twenty-one cases of cHCL and 9 cases of HCL-v were included. The median age at diagnosis was 55.5 (range, 30-86) years, with the ratio of male to female 2.75∶1. The main clinical manifestations included fatigue in 11 cases (36.7%), abdominal distension in 7 cases (23.3%), and infection in 4 cases, while 8 cases were asymptomatic. Splenomegaly was reported in 24 cases (80.0%), including 7 (23.3%) with megalosplenia. The white blood cell count, lymphocyte count, and the proportion of peripheral hairy cells in HCL-v group were significantly higher than those in cHCL group, whereas the development of anemia, thrombocytopenia, and monocytopenia in cHCL group was more remarkable than that in HCL-v group (all P<0.05). The BRAF-V600E gene mutation was detected only in cHCL patients (11/14 vs. 0/9, P<0.001). In terms of immunophenotype, the expression of CD25, CD103, CD123 and CD200 in cHCL group (20/20, 20/20, 4/7, 7/17) were all stronger than those in HCL-v group (3/9, 7/9, 0/4, 2/8). Twenty-two patients were treated, of which 13 cases (12 cases of cHCL and 1 case of HCL-v) with cladribine, and 9 cases (4 cHCL and 5 HCL-v) with interferon. Complete remission rate and overall response rate were comparable between cladribine and interferon treatment groups (both P<0.05). The median follow-up time was 31 (range, 1-125) months, and the median overall survival (OS) of the entire group was 125 months. The 5-year OS rate in HCL-v patients represented a trend of inferior (50.0% vs. 95.0%, P=0.207). Conclusions: The clinical features of HCL are unspecific, which includes fatigue, splenomegaly and recurrent infection. The clinical features, immunophenotype, treatment response and prognosis of HCL-v are different from those of cHCL. BRAF-V600E gene mutation is suggested as a key marker for differential diagnosis. Cladribine is recommended as front-line regimen of cHCL patients with satisfactory efficacy and prognosis. Conversely, response and clinical outcome in HCL-v patients still need to be improved.

Objective: The study investigated the efficacy and safety of daratumumab in the treatment of cardiac light chain (AL) amyloidosis. Methods: We retrospectively analyzed the clinical characteristics, hematologic response, organ response, long-term survival, and adverse events of 20 patients with newly diagnosed or relapsed/refractory cardiac AL amyloidosis treated with daratumumab in Peking Union Medical College Hospitalo from January 2017 to March 2021. Results: The overall median age of 20 patients was 62 (range, 45-73) yeas, with a male to female ratio of 2.3:1. Nine patients were newly diagnosed, while 11 patients had relapsed or refractory disease. Based on Mayo 2004 cardiac AL staging system, stages Ⅱ and Ⅲ diseases were present in 20 patients respectively. Four patients died during the first cycle of daratumumab, and the remaining 16 patients completed a median of 3 (range, 1-10) cycles of treatment. Overall hematologic response rates were 80% each at 1, 3, and 6 months after treatment initiation, and 45% , 60% , and 60% of the patients achieved at least a very good partial response at 1, 3, and 6 months respectively. The median duration to hematologic response was 13 (range, 6-28) days. At 3, 6, and 12 months, 20% , 30% , and 40% of the patients respectively achieved a cardiac response, and the median days to response was 91 (range, 30-216) days. As of the last follow-up, 9 (45% ) patients died. The 1-month mortality rate of all the patients and stage IIIb patients was 25% and 40% , respectively. The 1-year overall survival rate was 48.4% . Lymphocytopenia was the most common hematological adverse event (above grade 3) . Non-hematological adverse events were mainly infusion-related reactions and infections. Conclusion: Daratumumab could induce deep and rapid hematologic response in newly diagnosed and previously treated cardiac AL amyloidosis patients. However, daratumumab was not effective in preventing the high and early mortality rate in stage Ⅲb patients.

Objective: We investigated the impact of MYC/BCL-2 protein co-expression on the prognosis of diffuse large B-cell lymphoma (DLBCL) patients and observed whether double expression (DE) remains an independent poor prognostic factor in DLBCL after the addition of therapeutic factors such as DA-EPOCH-R, central prophylaxis, and transplantation. Methods: Available pathological findings were retrospectively collected from 223 DLBCL patients at the Peking Union Medical College Hospital from 2015 to 2018. Seventy-five patients with high MYC/BCL-2 expression were categorized as the DE group. From the 148 non-DE patients, 75 DLBCL patients were selected as the control group, using a 1∶1 matching on propensity scores for age, international prognostic index score, treatment choice, and etc. The differences in overall survival (OS) and progression-free survival (PFS) between the two groups were compared. Results: The 3-year OS was (69.8±5.5) % for the DE group and (77.0±4.9) % for the non-DE group (P=0.225) , while the 3-year PFS was (60.7±5.8) % and (65.3±5.5) % , respectively (P=0.390) . Subgroup analysis in patients treated with the R-CHOP regimen revealed that for the DE and non-DE patients, the 3-year OS was (61.3±7.5) % and (77.2±5.6) % (P=0.027) , and the 3-year PFS was (52.1±7.5) % and (70.6±6.0) % (P=0.040) , respectively. Multivariate analysis showed that age, stage of Ann Arbor, COO staging, whether central prophylaxis was performed, and whether transplantation was performed were significant independent risk factors of the prognosis of DLBCL patients (P<0.05) . On the other hand, MYC/BCL-2 protein double expression was not significantly associated with prognostic outcomes. Conclusion: MYC/BCL-2 protein double expression was significantly associated with poor prognosis under R-CHOP regimen treatment, but the poor prognostic impact of DE on DLBCL was eliminated under intensive regimens such as DA-EPOCH-R and transplantation.

Objective: To evaluate the clinical characteristics, treatment, and prognosis of patients with paraneoplastic neurological syndrome (PNS) associated with lymphoma. Methods: Between January 2012 and May 2021, the clinical data of 11 patients with lymphoma complicated with PNS treated at Peking Union Medical College Hospital were retrospectively reviewed. Results: Among the 11 patients (8 male and 3 female) , the median onset age was 61 (range, 33-78) years. The symptoms of PNS preceded lymphoma in 10 patients. The median time from the onset of PNS to the diagnosis of lymphoma was 4 months. Of the 11 patients, one had Hodgkin's lymphoma, 8 had B-cell non-Hodgkin's lymphoma, and 2 had peripheral T-cell lymphoma. Seven patients were evaluated for onconeural antibody, of whom 2 were positive (1 for anti-Ma2 antibody and 1 for anti-Yo antibody) . Of the 11 patients, the PNS symptoms of 3 patients were located in the central nervous system, 4 were located in the peripheral nervous system, and 3 were located in the muscle. Eight of the 11 patients were treated with glucocorticoid-based immunosuppressive therapy before the diagnosis of lymphoma. Patients with central nervous system involvement and dermatomyositis responded well to glucocorticoid, whereas patients with peripheral neuropathy did not significantly benefit. All 11 patients were treated with chemotherapy after the diagnosis of lymphoma. The efficacy of chemotherapy was assessed in 9 patients, 7 cases achieved complete remission, 1 case was evaluated as stable disease, and 1 case was evaluated as disease progression. The PNS symptoms of the patients who achieved complete response were almost completely recovered. The median follow-up time was 42 (range, 4-95) months. At the end of the follow-up period, 6 of the 11 patients survived, 3 were lost to follow-up, and 2 died. The median overall survival of the whole group was not reached. Conclusions: PNS can involve various parts of the nervous system and can be associated with different types of lymphoma. Through early diagnosis and treatment, the PNS symptoms could improve in most patients who achieve complete remission of lymphoma.

OBJECTIVE@#To investigate the clinical characteristics of patients with extranodal NK/T-cell lymphoma (ENKL), and to analyze the factors that affecting the survival and prognostic of patients treated with pegaspargase based chemotherapy.@*METHODS@#The clinical data of 61 ENKL patients treated in Peking Union Medical College Hospital from January 2015 to June 2019 were enrolled and retrospectively analyzed. The clinical characteristics, survival rate and influencing factors of prognostic in patients were investigated.@*RESULTS@#The male and female ratio in the whole group was 2.8∶1. The median age was 46 years old (range, 17-67 years old). 30 patients were in stage I/II, while 31 patients were in stage III/IV. The ratio of nasal and non-nasal type was 4.1∶1. The common sites of extranodal involvement were skin and subcutaneous tissue (26.2%), liver (14.8%), lung (13.1%) and gastrointestinal tract (13.1%). 9.8% of patients showed central nervous system involvement and 11.5% showed bone marrow involvement. The median follow-up time was 22 months (range, 1-53 months). The 2-year PFS and OS rates of patients in the whole group were 51.6% and 53.2%, respectively. The 2-year OS rate of patients at stage I/II was 87.5%, while that of patients at stage III/IV was only 21.2%, the difference showed statistically significant (P60 years old and Ann Arbor stage III-IV were the independent adverse factors that affecting the prognosis of PFS and OS (HR=3.681, 95% CI 1.322-10.250; HR=4.611, 95% CI 1.118-19.009).@*CONCLUSION@#The survival of ENKL patients has been significantly improved by pegaspargase based chemotherapy. Patients with stage I/II disease have achieved a relatively good 2-year OS rate of 87.5%, but the prognosis of stage III/IV and non-nasal type patients are still poor. Age>60 years old and Ann Arbor stage III/IV are independent adverse prognostic factors for ENKL patients.

BACKGROUND@#Bendamustine was approved in China on May 26th, 2019 by the National Medical Product Administration for the treatment of indolent B-cell non-Hodgkin lymphoma (NHL). The current study was the registration trial and the first reported evaluation of the efficacy, safety, and pharmacokinetics of bendamustine in Chinese adult patients with indolent B-cell NHL following relapse after chemotherapy and rituximab treatment.@*METHODS@#This was a prospective, multicenter, open-label, single-arm, phase 3 study (NCT01596621; C18083/3076) with a 2-year follow-up period. Eligible patients received bendamustine hydrochloride 120 mg/m2 infused intravenously on days 1 and 2 of each 21-day treatment cycle for at least six planned cycles (and up to eight cycles). The primary endpoint was the overall response rate (ORR); and secondary endpoints were duration of response (DoR), progression-free survival (PFS), safety, and pharmacokinetics. Patients were classified according to their best overall response after initiation of therapy. Proportions of patients in each response category (complete response [CR], partial response [PR], stable disease, or progressive disease) were summarized along with a two-sided binomial exact 95% confidence intervals (CIs) for the ORR.@*RESULTS@#A total of 102 patients were enrolled from 20 centers between August 6th, 2012, and June 18th, 2015. At the time of the primary analysis, the ORR was 73% (95% CI: 63%-81%) per Independent Review Committee (IRC) including 19% CR and 54% PR. With the follow-up period, the median DoR was 16.2 months by IRC and 13.4 months by investigator assessment; the median PFS was 18.6 months and 15.3 months, respectively. The most common non-hematologic adverse events (AEs) were gastrointestinal toxicity, pyrexia, and rash. Grade 3/4 neutropenia was reported in 76% of patients. Serious AEs were reported in 29 patients and five patients died during the study. Pharmacokinetic analysis indicated that the characteristics of bendamustine and its metabolites M3 and M4 were generally consistent with those reported for other ethnicities.@*CONCLUSION@#Bendamustine is an active and effective therapy in Chinese patients with relapsed, indolent B-cell NHL, with a comparable risk/benefit relationship to that reported in North American patients.@*CLINICAL TRIAL REGISTRATION@#ClinicalTrials.gov, No. NCT01596621; https://clinicaltrials.gov/ct2/show/NCT01596621.

Primary central nervous system lymphoma (PCNSL) is a rare group of extra-nodal non-Hodgkin lymphoma which is confined to the central nervous system or eyes. This article aims to present a brief profile of PCNSL diagnosis and treatment in immunocompetent patients. The authors retrieved information from the PubMed database up to September 2019. The annual incidence of PCNSL increased over the last four decades. The prognosis of PCNSL has improved mainly due to the introduction and wide-spread use of high-dose methotrexate, which is now the backbone of all first-line treatment polychemotherapy regimens. Gene expression profiling and next-generation sequencing analyses have revealed mutations that induce activation of nuclear factor-κB, B cell antigen receptor, and Janus kinases/signal transducer and activator of transcription proteins signal pathways. Some novel agents are investigated in the treatment of relapsed PCNSL including immunotherapy and targeted therapy. In particular, lenalidomide and ibrutinib have demonstrated durable efficiency. Treatment of PCNSL has evolved in the last 40 years and survival outcomes have improved in most patient groups, but there is still room to improve outcome by optimizing current chemotherapy and novel agents.
ABSTRACT
OBJECTIVE@#To determine the significance of morphology of bone marrow smear for diagnosis of bone marrow involvement in patients with diffuse large B-cell lymphoma (DLBCL), and to study the morphological characteristics of DLBCL cells involved in bone marrow.@*METHODS@#Four hundred and twenty cases of DLBCL diagnosed at Peking Union Hospital from 2006 to 2016 were analyzed and identified.@*RESULTS@#Blinded analysis of bone marrow smear and bone marrow biopsy data showed involvement in 42 cases on smears (S), in 47cases by biopsy (B) and the in 49 cases by (S+B). There was an excellent correlation between 2 methods diagnosing the bone marrow infiltration of DLBCL independently (κ=0.889). The morphological features of DLBCL cells involved in bone marrow were of medium sizes, round or irregular nuclear. The chromatin presented dark purple rea and coarse granular, and most of them had 1-5 nucleoli. The amount of cytoplasm was moderate with the color of dark blue or greyish blue. Vacuoles and pseudopodia were common.@*CONCLUSION@#The morphological examination of bone marrow cells has a certain role in the diagnosing bone marrow involvement in patients with DLBCL, and the atypical lymphoid cells making up ≥1% of the total nucleated cells highly suggests the bone marrow involvement in the patients with DLBCL.

OBJECTIVE@#To investigate the clinical value of erythrocyte life span in the diagnosis and treatment of lymphoma patients with anemia.@*METHODS@#The clinical data of 45 patients with lymphoma diagnosed by Department of Hematology in Beijing Union Hospital from January 2017 to June 2017 were collected. The life of erythrocytes was detected by alveolar gas CO test.@*RESULTS@#The incidence of anemia in patients with malignant lymphoma was 46.7%, 40.0% of patients displayed the shorting of blood cell life and the hemolytic status existed in 15.56% of patients. The incidence of anemia was 47.1% in patients with DLBCL. Patients with B symptoms, bone marrow involvement, splenomegaly or LDH increase often accompanied with anemia, but only the splenomegaly and LDH level were significantly negatively correlated with red blood cell life; there was a significant difference in the effects of CHOP ± R regimen and other chemotherapy regimens (R+MINE/FC/SMILE/GDP) on patients with anemia and erythrocyte life span.@*CONCLUSION@#The incidence of anemia in patients with lymphoma is high, red cell damage or shortened life may be involved in the mechanism of anemia, the use of a strong chemotherapy regimen can significantly shorten the red blood cell life of patients and aggravates anemia.

Objective: To evaluate the feasibility and potential value of comprehensive geriatric assessment (CGA) in elderly (≥60 years) patients with newly diagnosed acute myeloid leukemia (AML) in China. Methods: The CGA results of 83 newly diagnosed AML (non-APL) patients from 16 hospitals in Beijing and Tianjin between March 2016 and December 2017 were prospectively collected and analyzed. The clinical data, treatment and follow-up information were also collected. Results: Of 83 newly diagnosed elderly AML patients, 81 patients (97.6%) completed all designated CGA assessment. The median number of impaired scales of the CGA assessment in the studied population was 2(0-6). Sixteen patients (19.3%) showed no impairments according to the geriatric assessment scales implem ented by this study. The distributions of impaired scales were as follows: impairment in ADL, 55.4%; IADL impairment, 42.2%; MNA-SF impairment, 48.2%; cognitive impairment, 15.7%; GDS impairment, 31.7%; HCT-CI impairment, 19.5%, respectively. In patients with "good" ECOG (n=46), the proportion of impairment for each CGA scale ranged from 6.5% to 37.0% and 32 patients (68.9%) had at least one impaired CGA scale. Survival analysis showed that the number of impaired scales of the CGA was significantly correlated with median overall survival (P=0.050). Conclusions: CGA was a tool with feasibility for the comprehensive evaluation in elderly AML patients in China. Combined with age and ECOG, CGA may be more comprehensive in assessing patients' physical condition.

ABSTRACT
Objective: To Evaluate the efficacy and safety of posaconazole as primary prevention of invasive fungal disease (IFD) in patients with severe aplastic anemia (SAA) treated with anti-thymus/lymphocyte immunoglobulin (ATG/ALG) combined with cyclosporine intensive immunosuppressive therapy (IST). Methods: A retrospective analysis of clinical data of 58 SAA patients who received IST of anti-thymocyte immunoglobulin combining cyclosporine and antifungal prophylaxis during April 2013 to May 2017 in Peking Union Medical College Hospital was performed. The patients were divided into posaconazole prophylaxis group and the control group (itraconazole or fluconazole). The disease characteristics, IFD prevention effect and adverse drug reaction, curative effect and prognosis of the two groups were compared. Results: Posaconazole was used to prevent fungal infection in 20 patients. The other 38 patients were used as the control group. Retrospective analysis showed comparable characteristics (gender, age, disease severity, etiology, interval between the onset of disease to treatment, ATG/ALG type) of both groups. The incidence of IFD were 0 and 15.8% in posaconazole prophylaxis group and the control group, respectively (P=0.084). In the control group, there were 6 cases diagnosed as IFD. Of them, 2 were confirmed, 2 suspected and 2 not identified. Five of the 6 cases were pulmonary infection, 1 bloodstream infections. Of the 6 IFD cases, 5 were very severe aplastic anemia (VSAA). There was no obvious adverse reaction in posaconazole prophylaxis group. Conclusion: Posaconazole is safe and effective for primary prevention of fungal infection of SAA patients receiving IST, especially for the VSAA.

Objective: To evaluate the response of oral melphalan plus high-dose dexamethasone (MDex) for patients with primary light chain amyloidosis (pAL). Methods: Clinical data, hematological and organ responses, and survival of 76 patients with pAL who had received MDex from January 2009 to July 2017 were retrospectively analyzed. Results: Of 76 patients (47 males and 29 females with the median age of 56 [range, 20-74] years old), 19.70% patients were defined as Mayo 2004 stage 3, involvement of more than or two organs was presented in 65 (85.53%) patients. Among 60 response evaluable patients, overall hematological response was 48.33% with complete response of 20.00% and very good partial response of 20.00%, respectively. The median time to the hematological response was 5 (range, 1-15) months. 36.67% patients achieved organ response. After the median follow up of 23(range, 1-113) months for surviving patients, median progression-free survival (PFS) and overall survival (OS) were 34 and 43 months, respectively. In a three months landmark analysis, the median rates of PFS and OS were 46 and 65 months, respectively. The median OS rates of patients with Mayo 2004 stage 3 and non Mayo 2004 stage 3 were 5 and 65 months (P=0.001), respectively. Conclusions: MDex was an effective treatment for patients with early stage pAL, but was not suitable for those with severe cardiac involvement.

Objective: To report the first case of lymphomatoid gastropathy in China, and to demonstrate the clinical characteristics, diagnostic approach, treatment and prognosis in this kind of patients. Methods: One patient was diagnosed as lymphomatoid gastropathy at Peking Union Medical College Hospital, and her clinical characteristics, lab data, treatment and follow-up outcomes were reviewed. Results: A case of a 51-year-old female was presented, who underwent esophagogastroduodenoscopy (EGD) due to slight epigastric discomfort. EGD revealed multiple ulcers and erosions. Biopsies showed atypical lymphocytes infiltration with CD3(+), CD56(+), CD20(-), CD8(-), TIA(+), Granzyme B(-) and Ki-67 (75%). Epstein-Barr virus-encoded RNA in situ hybridization was negative. Four months later, repeated EGD examination showed regression of the lesions without specific treatment. Conclusion: Lymphomatoid gastropathy was a unique disease entity mimicking NK/T-cell lymphomas in pathology, with the quite different profile of treatment and prognosis. It's important to consider this issue during the differential diagnosis to avoid any excessive treatment.

Objective: To investigate clinic-pathological characteristics, diagnosis, treatment and prognosis of intravascular large B cell lymphoma (IVLBCL) in China. Methods: Clinical and pathological records were analyzed from 12 IVLBCL patients diagnosed between Jan 2010 to Jun 2016. Kaplan-Meier method was used to estimate overall survival (OS), and univariate analysis was performed to identify prognostic factors. Results: A series of 12 patients with IVLBCL (median age, 53.8 years; range, 32-76 years; 6 males and 6 females) was reviewed. Fever was the most common symptom (10/12), respiratory symptoms (cough, pleural effusion, dyspnea, 50%) and hemophagocytic lymphohistiocytosis (50%) were frequently observed, and only 12 patients had neurological symptom. All patients had elevated lactic dehydrogenase and serum ferritin. International Prognostic Index score was high in 75% of total patients. All patients had extra-nodal involved, pulmonary (6/12) and bone marrow (4/12) were frequently involved. Large lymphoid cells within vessel lumina or sinuses were observed in all patients. These cells were large, with scant cytoplasm, vesicular nuclei, and one or more nucleoli, and the structures of vessels and sinus were reserved. CD20 and CD79a were positive in all cases. 11patients received rituximab combined CHOP regimen chemotherapies, overall response rate (ORR) was 90.1%, and complete response rate was 66.7%. Median survival time and median progression time were not reached after a median follow-up of 20 months. Univariate analysis revealed that no clinical characters were associated with OS. Conclusion: As a rare variant of DLBCL, IVLBCL presented with pulmonary involved frequently, and trans-bronchial lung biopsy had good positive rates. Rituximab contained chemotherapy was the backbone for IVLBCL.

Objective To investigate the clinical features of unicentric Castleman's disease(UCD)with paraneoplastic pemphigus(PNP)and bronchiolitis obliterans(BO).Method Data of UCD patients with PNP and BO from Peking Union Medical College Hospital were retrospectively analyzed,along with literatures review. Results Totally 23 cases(11 males and 12 females)were enrolled.The median age was 31 years(13-56 years).The most common pathological type was hyaline-vascular variant(91.4%),and most tumors located in abdominopelvic cavity(69.6%).Considerable cases presented bulky masses(26.3%).Most cases were first diagnosed on presentation with the symtoms of PNP(90.0%).BO was characterized by progressive dyspnea after excision of CD lesions.The average follow-up duration was 27.5 months(1-135 months).The median overall survival time was 36.0 months(95% CI=13.9-58.1).Respiratory failure was the dominant cause of death(91.7%).Conclusions PNP should be considered among those patients with specific oral or cutaneous lesions.Earlier diagnosis and treatment of latent UCD are important for reducing complications and deaths.
