ABSTRACT

BACKGROUND@#To compare the efficacy and safety of dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin plus rituximab (DA-EPOCH-R) with standard rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in Waldeyer's ring diffuse large B-cell lymphoma (WR-DLBCL) at a single institution.@*METHODS@#This retrospective study included 115 newly diagnosed patients with WR-DLBCL, of whom 68 patients received R-CHOP, and 47 patients received DA-EPOCH-R as their first-line treatment. The baseline features of the two groups were well balanced using a 1:1 propensity score matching method, and a total of 84 cases were obtained, including respective 42 cases in the R-CHOP and DA-EPOCH-R groups, for further survival and prognosis analysis. The primary objectives included progression-free survival (PFS) and overall survival (OS).@*RESULTS@#During a median follow-up of 45 months, there were nine (21.4%) deaths in the R-CHOP group and two (4.8%) in the DA-EPOCH-R group. Kaplan-Meier analysis showed statistically significant improvements in PFS and OS in patients with DA-EPOCH-R compared with those treated with R-CHOP (log-rank test, P  = 0.025 and P  = 0.035, respectively). The 2-year PFS and OS rates in the DA-EPOCH-R group were 90.1% (95% confidence interval [CI]: 81.4-99.8%) and 95.2% (95% CI: 89.0-100.0%), respectively, and 80.5% (95% CI: 69.3-93.6%) and 90.5% (95% CI: 52.8-99.8%) in the R-CHOP group. Patients without B symptoms and elevated lactate dehydrogenase levels had a higher PFS in the DA-EPOCH-R group, with P values of 0.038 (hazard ratio [HR]: 0.11; 95% CI: 0.01-0.88) and 0.042 (HR: 0.19; 95% CI: 0.04-0.94), respectively. There were no statistically significant differences in clinical responses and treatment-related toxicities between the two groups.@*CONCLUSION@#Compared with patients received R-CHOP, those treated by DA-EPOCH-R had superior PFS, OS, and controlled toxicity in patients with WR-DLBCL.

ABSTRACT

Objective: To further elucidate the clinical efficacy and safety of a combination regimen based on the BTK inhibitor zebutanil bridging CD19 Chimeric antigen receptor T cells (CAR-T cells) in the treatment of relapsed/refractory diffuse large B-cell lymphoma (r/r DLBCL) . Methods: Twenty-one patients with high-risk r/r DLBCL were treated with a zanubrutinib-based regimen bridging CAR-T between June 2020 and June 2023 at the Department of Hematology, Tongji Hospital, Tongji University and the Second Affiliated Hospital of Zhejiang University, and the efficacy and safety were retrospectively analyzed. Results: All 21 patients were enrolled, and the median age was 57 years (range: 38-76). Fourteen patients (66.7%) had an eastern cooperative oncology group performance status score (ECOG score) of ≥2. Eighteen patients (85.7%) had an international prognostic index (IPI) score of ≥3. Three patients (14.3%) had an IPI score of 2 but had extranodal infiltration. Fourteen patients (66.7%) had double-expression of DLBCL and seven (33.3%) had TP53 mutations. With a median follow-up of 24.8 (95% CI 17.0-31.6) months, the objective response rate was 81.0%, and 11 patients (52.4%) achieved complete remission. The median progression-free survival (PFS) was 12.8 months, and the median overall survival (OS) was not reached. The 1-year PFS rate was 52.4% (95% CI 29.8% -74.3%), and the 1-year OS rate was 80.1% (95% CI 58.1% -94.6%). Moreover, 18 patients (85.7%) had grade 1-2 cytokine-release syndrome, and two patients (9.5%) had grade 1 immune effector cell-associated neurotoxicity syndrome. Conclusion: Zanubrutinib-based combination bridging regimen of CAR-T therapy for r/r DLBCL has high efficacy and demonstrated a good safety profile.

ABSTRACT

Objective: To analyze the clinical characteristics and prognosis of primary and secondary pancreatic diffuse large B-cell lymphoma (DLBCL) . Methods: Clinical data of patients with pancreatic DLBCL admitted at Shanghai Rui Jin Hospital affiliated with Shanghai Jiao Tong University School of Medicine from April 2003 to June 2020 were analyzed. Gene mutation profiles were evaluated by targeted sequencing (55 lymphoma-related genes). Univariate and multivariate Cox regression models were used to evaluate the prognostic factors of overall survival (OS) and progression-free survival (PFS) . Results: Overall, 80 patients were included; 12 patients had primary pancreatic DLBCL (PPDLBCL), and 68 patients had secondary pancreatic DLBCL (SPDLBCL). Compared with those with PPDLBCL, patients with SPDLBCL had a higher number of affected extranodal sites (P<0.001) and had higher IPI scores (P=0.013). There was no significant difference in the OS (P=0.120) and PFS (P=0.067) between the two groups. Multivariate analysis indicated that IPI intermediate-high/high risk (P=0.025) and double expressor (DE) (P=0.017) were independent adverse prognostic factors of OS in patients with pancreatic DLBCL. IPI intermediate-high/high risk (P=0.021) was an independent adverse prognostic factor of PFS in patients with pancreatic DLBCL. Targeted sequencing of 29 patients showed that the mutation frequency of PIM1, SGK1, BTG2, FAS, MYC, and MYD88 in patients with pancreatic DLBCL were all >20%. PIM1 (P=0.006 for OS, P=0.032 for PFS) and MYD88 (P=0.001 for OS, P=0.017 for PFS) mutations were associated with poor OS and PFS in patients with SPDLBCL. Conclusion: There was no significant difference in the OS and PFS between patients with PPDLBCL and those with SPDLBCL. IPI intermediate-high/high risk and DE were adverse prognostic factors of pancreatic DLBCL. PIM1, SGK1, BTG2, FAS, MYC, and MYD88 were common mutations in pancreatic DLBCL. PIM1 and MYD88 mutations indicated worse prognosis.

ABSTRACT

OBJECTIVE@#To investigate the expression and prognostic value of cytokines in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL).@*METHODS@#Clinical data of 62 patients diagnosed with DLBCL in the First People's Hospital of Yunnan Province from June 2017 to November 2018 were collected. The differences in expression levels of 14 serum cytokines [interleukin (IL)-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-17A, IL-17F, IL-22, interferon (IFN)-γ, tumor necrosis factor (TNF)-α, TNF-β] in patients with different survival outcomes, and the impact of the cytokines on 3-year progression-free survival (PFS) and 3-year overall survival (OS) of patients with DLBCL were analyzed retrospectively.@*RESULTS@#Among the 14 cytokines, only the expression of IL-10 was significantly different in patients with different survival outcomes (P =0.007). According to the receiver operating characteristic (ROC) curve, the optimal cut-off value for IL-10 was 11.74 pg/ml. Serum IL-10 was positively correlated with infection markers procalcitonin (PCT) (r =0.321, P =0.029), C-reactive protein (CRP) (r =0.320, P =0.013) and tumor burden index lactate dehydrogenase (LDH) (r =0.439, P <0.001) in newly diagnosed DLBCL patients. The level of IL-10 in patients with pulmonary infection was significantly higher than that in patients without pulmonary infection (P =0.012). However, there was no statistically significant difference on the 3-year survival outcomes between patients with or without pulmonary infection. There was no significant difference in IL-10 level in patients with different Ann Arbor stages (P >0.05). Patients with high IL-10 level (IL-10>11.74 pg/ml) had significantly higher LDH level than those with low IL-10 level (IL-10≤11.74 pg/ml) (P <0.001). The 3-year PFS rate and 3-year OS rate of DLBCL patients with high IL-10 level were significantly lower than those of low IL-10 level group [(44.4±11.7)% vs (81.8±5.8)%, P <0.001; (61.6±11.5)% vs (93.2±3.8)%, P =0.001].@*CONCLUSION@#Serum IL-10 level in newly diagnosed DLBCL patients can reflect the inflammatory state of the body, which may be related to tumor load. Newly diagnosed DLBCL patients with serum IL-10>11.74 pg/ml have higher early mortality and worse prognosis.

ABSTRACT

OBJECTIVE@#To explore the short-term efficacy and adverse reactions of orelabrutinib combined with high-dose methotrexate (HD-MTX) in the first-line treatment of elderly high-risk primary central nervous system lymphoma (PCNSL), as well as the survival of patients.@*METHODS@#Twenty-five elderly patients with high-risk primary central nervous system diffuse large B-cell lymphoma admitted to Fujian Provincial Hospital from June 2016 to June 2022 were enrolled in this study, and complete clinical data from all patients were collected retrospectively, and the cut-off for follow-up was December 2022. 15 patients had received temmozolomide combined with HD-MTX regimen for at least four cycles, sequential lenalidomide maintenance therapy, while 10 patients had received orelabrutinib combined with HD-MTX regimen for at least four cycles, sequential orelabrutinib maintenance therapy. The short-term efficacy and adverse reactions of the two groups of patients after treatment were observed. Kaplan-Meier was used to analyze the progression-free survival (PFS) and time to progression (TTP).@*RESULTS@#The objective response rate (ORR) and 2-year median FPS of orelabrutinib combined with HD-MTX regimen group were similar to the temozolomide combined with HD-MTX regimen group (ORR: 100% vs 66.7%; 2-year median PFS: 16 months vs 15 months, P>0.05). The 2-year median TTP of the orelabrutinib+HD-MTX regimen group was better than that of the temozolomide+HD-MTX regimen group (not reached vs 12 months, P<0.05). There were no significant differences in adverse reactions such as gastrointestinal reactions, bone marrow suppression, liver and kidney damage, cardiotoxicity, pneumonia and bleeding between these two groups (P>0.05).@*CONCLUSION@#For elderly patients with high-risk PCNSL, orelabrutinib combined with HD-MTX has reliable short-term efficacy, good safety, and tolerable adverse reactions, which is worthy of clinical promotion.

ABSTRACT

OBJECTIVE@#To investigate the value of pre-treatment albumin/fibrinogen ratio (AFR) on the prognosis of patients with diffuse large B-cell lymphoma (DLBCL).@*METHODS@#The data of DLBCL patients in the Affiliated Hospital of North Sichuan Medical College from April 2014 to March 2021 were retrieved, and 111 newly diagnosed patients who completed at least 4 cycles of R-CHOP or R-CHOP-like chemotherapy with complete data were included in the study. The clinical, laboratory examination and follow-up data of the patients were collected, and the receiver operating characteristic curve (ROC) was drawn according to patients' AFR before treatment and the survival status at the end of the follow-up, which could be used to preliminarily evaluate the predictive value of AFR for disease progression and patients' survival outcome. Furthermore, the correlation of AFR with the clinical and laboratory characteristics, progression-free survival (PFS) and overall survival (OS) was analyzed, and finally, univariate and multivariate Cox proportional hazard regression models were used to analyze factors affecting PFS and OS of DLBCL patients.@*RESULTS@#The ROC curve indicated that AFR level had a moderate predictive value for PFS and OS in DLBCL patients, with the area under the curve (AUC) of 0.616 (P =0.039) and 0.666 (P =0.004), respectively, and the optimal cut-off values were both 9.06 for PFS and OS. Compared with high-AFR (≥9.06) group, the low-AFR (<9.06) group had a higher proportion of patients with Lugano III-IV stage ( P <0.001), elevated lactate dehydrogenase (P =0.007) and B symptoms (P =0.038). The interim analysis of response showed that the overall response rate (ORR) in the high-AFR group was 89.7%, which was significantly higher than 62.8% in the low-AFR group (P =0.001). With a median follow-up of 18.5 (3-77) months, the median PFS of the high-AFR group was not reached, which was significantly superior to 17 months of the low-AFR group (P =0.009). Similarly, the median OS of high-AFR group was not reached, either, which was significantly superior to 48 months of the low-AFR group (P < 0.001). In multivariate Cox regression analysis, AFR <9.06 was an independent risk factor both for PFS and OS (HR PFS=2.047, P =0.039; HR OS=4.854, P =0.001).@*CONCLUSION@#Pre-treatment AFR has a significant value for the prognosis evaluation in newly diagnosed DLBCL patients.

ABSTRACT

OBJECTIVE@#To retrospectively analyze clinical characteristics and survival time of patients with diffuse large B-cell lymphoma (DLBCL), detect prognosis-related markers, and establish a nomogram prognostic model of clinical factors combined with biomarkers.@*METHODS@#One hundred and thirty-seven patients with DLBCL were included in this study from January 2014 to March 2019 in the First Affiliated Hospital of Nanchang University. The expression of GCET1, LMO2, BCL-6, BCL-2 and MYC protein were detected by immunohistochemistry (IHC), then the influences of these proteins on the survival and prognosis of the patients were analyzed. Univariate and multivariate Cox regression analysis were used to gradually screen the prognostic factors in nomogram model. Finally, nomogram model was established according to the result of multivariate analysis.@*RESULTS@#The positive expression of GCET1 protein was more common in patients with Ann Arbor staging I/II (P =0.011). Compared with negative patients, patients with positive expression of LMO2 protein did not often show B symptoms (P =0.042), and could achieve better short-term curative effect (P =0.005). The overall survival (OS) time of patients with positive expression of LMO2 protein was significantly longer than those with negative expression of LMO2 protein (P =0.018), though the expression of LMO2 protein did not correlate with progression-free survival (PFS) (P >0.05). However, the expression of GCET1 protein had no significant correlation with OS and PFS. Multivariate Cox regression analysis showed that nomogram model consisted of 5 prognostic factors, including international prognostic index (IPI), LMO2 protein, BCL-2 protein, MYC protein and rituximab. The C-index applied to the nomogram model for predicting 4-year OS rate was 0.847. Moreover, the calibrated curve of 4-year OS showed that nomogram prediction had good agreement with actual prognosis.@*CONCLUSION@#The nomogram model incorporating clinical characteristics and IHC biomarkers has good discrimination and calibration, which provides a useful tool for the risk stratification of DLBCL.

ABSTRACT

Objective: To investigate the potential value of CT Radiomics model in predicting the response to first-line chemotherapy in diffuse large B-cell lymphoma (DLBCL). Methods: Pre-treatment CT images and clinical data of DLBCL patients treated at Shanxi Cancer Hospital from January 2013 to May 2018 were retrospectively analyzed and divided into refractory patients (73 cases) and non-refractory patients (57 cases) according to the Lugano 2014 efficacy evaluation criteria. The least absolute shrinkage and selection operator (LASSO) regression algorithm, univariate and multivariate logistic regression analyses were used to screen out clinical factors and CT radiomics features associated with efficacy response, followed by radiomics model and nomogram model. Receiver operating characteristic (ROC) curve, calibration curve and clinical decision curve were used to evaluate the models in terms of the diagnostic efficacy, calibration and clinical value in predicting chemotherapy response. Results: Based on pre-chemotherapy CT images, 850 CT texture features were extracted from each patient, and 6 features highly correlated with the first-line chemotherapy effect of DLBCL were selected, including 1 first order feature, 1 gray level co-occurence matrix, 3 grey level dependence matrix, 1 neighboring grey tone difference matrix. Then, the corresponding radiomics model was established, whose ROC curves showed AUC values of 0.82 (95% CI: 0.76-0.89) and 0.73 (95% CI: 0.60-0.86) in the training and validation groups, respectively. The nomogram model, built by combining validated clinical factors (Ann Arbor stage, serum LDH level) and CT radiomics features, showed an AUC of 0.95 (95% CI: 0.90-0.99) and 0.91 (95% CI: 0.82-1.00) in the training group and the validation group, respectively, with significantly better diagnostic efficacy than that of the radiomics model. In addition, the calibration curve and clinical decision curve showed that the nomogram model had good consistency and high clinical value in the assessment of DLBCL efficacy. Conclusion: The nomogram model based on clinical factors and radiomics features shows potential clinical value in predicting the response to first-line chemotherapy of DLBCL patients.

ABSTRACT

Objective: To analyze the clinicopathologic characteristics and prognosis of testicular diffuse large B-cell lymphoma (DLBCL) . Methods: A retrospective analysis was performed on 68 patients with testicular DLBCL admitted to Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine from October 2001 to April 2020. The gene mutation profile was evaluated by targeted sequencing (55 lymphoma-related genes) , and prognostic factors were analyzed. Results: A total of 68 patients were included, of whom 45 (66.2% ) had primary testicular DLBCL and 23 (33.8% ) had secondary testicular DLBCL. The proportion of secondary testicular DLBCL patients with Ann Arbor stage Ⅲ-Ⅳ (P<0.001) , elevated LDH (P<0.001) , ECOG score ≥ 2 points (P=0.005) , and IPI score 3-5 points (P<0.001) is higher than that of primary testicular DLBCL patients. Sixty-two (91% ) patients received rituximab in combination with cyclophosphamide, adriamycin, vincristine, and prednisone (R-CHOP) -based first-line regimen, whereas 54 cases (79% ) underwent orchiectomy prior to chemotherapy. Patients with secondary testicular DLBCL had a lower estimated 5-year progression-free survival (PFS) rate (16.5% vs 68.1% , P<0.001) and 5-year overall survival (OS) rate (63.4% vs 74.9% , P=0.008) than those with primary testicular DLBCL, and their complete remission rate (57% vs 91% , P=0.003) was also lower than that of primary testicular DLBCL. The ECOG scores of ≥2 (PFS: P=0.018; OS: P<0.001) , Ann Arbor stages Ⅲ-Ⅳ (PFS: P<0.001; OS: P=0.018) , increased LDH levels (PFS: P=0.015; OS: P=0.006) , and multiple extra-nodal involvements (PFS: P<0.001; OS: P=0.013) were poor prognostic factors in testicular DLBCL. Targeted sequencing data in 20 patients with testicular DLBCL showed that the mutation frequencies of ≥20% were PIM1 (12 cases, 60% ) , MYD88 (11 cases, 55% ) , CD79B (9 cases, 45% ) , CREBBP (5 cases, 25% ) , KMT2D (5 cases, 25% ) , ATM (4 cases, 20% ) , and BTG2 (4 cases, 20% ) . The frequency of mutations in KMT2D in patients with secondary testicular DLBCL was higher than that in patients with primary testicular DLBCL (66.7% vs 7.1% , P=0.014) and was associated with a lower 5-year PFS rate in patients with testicular DLBCL (P=0.019) . Conclusion: Patients with secondary testicular DLBCL had worse PFS and OS than those with primary testicular DLBCL. The ECOG scores of ≥2, Ann Arbor stages Ⅲ-Ⅳ, increased LDH levels, and multiple extra-nodal involvements were poor prognostic factors in testicular DLBCL. PIM1, MYD88, CD79B, CREBBP, KMT2D, ATM, and BTG2 were commonly mutated genes in testicular DLBCL, and the prognosis of patients with KMT2D mutations was poor.

ABSTRACT

Objective: This study aimed to look into the clinical characteristics and prognosis of patients with human immunodeficiency virus (HIV) -associated diffuse large B-cell lymphoma (DLBCL) . Methods: Retrospective review of the clinical data of 63 HIV-infected patients with DLBCL diagnosed at Chongqing University Cancer Hospital between July 2008 and August 2021. The Kaplan-Meier method was used to calculate survival curves, and the log-rank test method was used to compare survival between groups. The Cox proportional hazards model was used for multivariate analysis. Results: In 63 patients with HIV-associated DLBCL, 57 (90.5% ) were men, and the median age was 49 (23-87) years. The most common pathological subtype was the germinal center B-cell-like lymphoma (74.6% ) ; 46.0% (29/63) were combined with extranodal lesions. Seventeen of 63 (27.0% ) patients had large masses (≥7.5 cm) . Twenty of 63 (31.7% ) patients had B symptoms. The median CD4(+) T cell count was 203 (4-1022) ×10(6)/L. A total of 49% (25/51) patients had CD4(+) cell count <200×10(6)/L, 56.9% (33/58) had high (3-5) International Prognostic Index (IPI) scores, and 43.1% (25/58) had low (0-2) IPI scores. Further, 78% (46/59) were diagnosed with Ann Arbor Stage Ⅲ/Ⅳ, and 25.4% (16/63) didn't receive chemotherapy. A total of 22.2% (14/63) of patients received less than four cycles of chemotherapy, and 52.4% (33/63) received four or more cycles of chemotherapy. Among patients undergoing chemotherapy, 61.7% (29/47) received R-CHOP-like regimens, and 38.3% (18/47) used CHOP-like regimens. The 1-, 2-, 3-, and 5-year overall survival (OS) rates were 65.0% , 53.8% , 47.1% , and 43.5% , respectively. Univariate analysis revealed that age ≥ 60 years (P=0.012) , Eastern Cooperative Oncology Gruop Performance Status (ECOG-PS) score 2-4 points (P=0.043) , IPI score 3-5 points (P=0.001) , β(2)-MG elevation (≥5.5 mg/L) (P=0.007) , and systemic chemotherapy cycles less than four times (P<0.001) were the negative prognostic factors affecting the OS of patients. The Cox multivariate analysis depicted that age ≥60 years (HR=2.272, 95% CI 1.110-4.651, P=0.025) , IPI score 3-5 points (HR=3.562, 95% CI 1.794-7.074, P<0.001) , ECOG-PS score 2-4 points (HR=2.675, 95% CI 1.162-6.153, P=0.021) , and number of cycles of chemotherapy<4 (HR=0.290, 95% CI 0.176-0.479, P<0.001) were independent risk factors for adverse prognosis of OS. Conclusion: HIV-associated DLBCL is the most common HIV-related tumor, is most commonly seen in men, and has a high 1-year mortality rate. Chemotherapy combined with antiretroviral therapy can improve patient prognosis.

ABSTRACT

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.

ABSTRACT

Objective: To investigate the distribution characteristics of LymphGen genotyping in a diffuse large B-cell lymphoma (DLBCL) population and verify its prognostic value. Methods: We collected the clinical data and paraffin-embedded tumor tissue samples of 155 patients with newly diagnosed DLBCL in the People's Hospital of Xinjiang Uygur Autonomous Region from June 2014 to December 2020. DNA was extracted from tumor tissue and 475 gene mutations were detected by next-generation sequencing technology. We investigated the distribution of LymphGen genotyping in the DLBCL population, patients with different COO genotypes in the Xinjiang region, and their effects on PFS and OS. Results: ①Among 155 patients, 105 patients (67.7%) could be genotyped, including 14 (9.0%) for MCD, 26 (16.8%) for BN2, 10 (6.5%) for N1, 8 (5.2%) for EZB, 27 (17.4%) for A53, and 20 (12.9%) for ST2. ②The distribution of each gene subtype was different in different cell origin (COO) types (P=0.021) . ST2 was dominant in the germinal center type (GCB) group (28.8%) , and A53 and MCD were dominant in the non-GCB group (35.8%, 17.0%) . The BN2 type was the most common in both groups (23.1%, 26.4%) . ③There were statistically significant differences in progression-free survival (PFS) and overall survival (OS) among different gene subtypes (P=0.031 and 0.005, respectively) . N1 and A53 had poor prognosis. The 2-year PFS and OS rates of N1 were both (21.3±18.4) %, and the 3-year PFS and OS rates of A53 were (60.9±11.3) %, (46.8±10.9) %, respectively. ④ The 3-year PFS and OS rates of MCD were the best, but the 5-year PFS and OS rates were worse. ⑤In the ROC curve of LymphGen genotyping for OS prediction, the AUC was 0.66, showing a certain degree of differentiation. Conclusion: LymphGen genotyping in the DLBCL population was different from previous reports and was of great significance for the prognosis of patients with DLBCL.

ABSTRACT

OBJECTIVE@#To analyze the clinical characteristics and long-term prognosis of patients with primary bone lymphoma (PBL).@*METHODS@#The clinical data of 21 patients with PBL treated in our center from 2005 to 2018 were analyzed retrospectively, the clinical characteristics and the factors affecting prognosis of the patients were analyzed.@*RESULTS@#The median age of all the 21 newly diagnosed PBL patients was 40(12-71) years old. Ostealgia was the initial symptom in most of the patients (19/21,90.5%). 42.9%(9/21) of the patients showed single bone lesion only. 571% (12/21) of the patients showed diffuse large B cell lymphoma. 28.6% (6/21) of the patients showed anaplastic large cell lymphoma and 9.5% (2/21) of the patients showed T cell lymphoblastic lymphoma. All the patients received chemotherapy (CHOP or CHOP like regimen, 33.3% plus rituximab) with or without radiotherapy and/or autologous hematopoietic stem cell transplantation (ASCT). 18 patients achieved clinical remission (including 15 for CR and 3 for PR). The median follow-up time was 48 months. The 5-year overall survival rate and progression-free survival rate of the patients were was 67.5% and 63.7%, respectively. The single factors analysis showed that ASCT was the important prognostic factor of PFS, while the single or multiple bone lesion was the factors affecting OS of the patients. There were no statistical differences with the effects of age, sex, stage, ECOG score, LDH level, B symptoms and radiotherapy for the prognosis of patients.@*CONCLUSION@#Diffuse large B cell lymphoma is the most common pathological type of PBL. Chemotherapy is the main treatment, which can be combined with radiotherapy and/or ASCT. The ASCT and the number of bone lesion are the factors for long time survival of the patients.

ABSTRACT

Background: Central nervous system international prognosis index (CNS-IPI) is validated in European and the USA cancer databases. However, no validation has been done in Mexican population. Objective: The objective of the study was to assess the impact of the CNS-IPI on central nervous system (CNS) relapse and survival in Mexican patients with diffuse large B-cell lymphoma (DLBCL). Methods: In this retrospective analysis, clinical, biochemical, and histological variables and the CNS-IPI were analyzed. Results: Six hundred and forty-two patients with DBLCL were included in the study. The mean ± SD age was 56.8 ± 14.9 years. Most had an ECOG of 0-1: 75% (n = 484) had absence of B-symptoms and advanced disease (clinical stage: III-IV, n = 433, 67.4%). According to the CNS-IPI, almost one-half were in the low-risk category. According to the CNS-IPI, CNS relapse rate was 1.36% (95% CI: 83.2-92.8), 3.1% (95% CI: 132.4-162.8), and 7.4% (95% CI 61-91) for patients in the low-, intermediate-, and high-risk categories, respectively. The median overall survival in the high-risk group (CNS-IPI) was 22 months, and it has not been achieved after 80 months of follow-up for the other groups. Conclusions: CNS-IPI was associated with survival; therefore, we propose its use as a prognostic tool for prospective validation.

ABSTRACT

ABSTRACT Primary myocardial involvement of Diffuse Large B-Cell lymphoma is extremely rare, accounting for 0.5 % of all lymphomas. We report a 65-year-old male, presenting with an acute cardiac tamponade, which was drained. A pericardial window with myocardial biopsy was carried out, disclosing a diffuse large B cell lymphoma. He received 6 cycles of rituximab, cyclophosphamide, vincristine, and prednisone (R-CVP), without response. Finally, a palliative chemotherapy with gemcitabine plus oxaliplatin was prescribed.


El linfoma difuso de células grandes B, primario del miocardio es muy raro. Presentamos un varón de 65 años que se presentó con un taponamiento cardíaco agudo que fue drenado. La biopsia miocárdica un mostró linfoma difuso de células grandes B, primario de miocardio. El paciente recibió 6 ciclos de quimioterapia con rituximab, ciclofosfamida, vincristina y prednisona sin respuesta. Finalmente se optó por una quimioterapia paliativa con gemcitabina y oxaliplatino.

ABSTRACT

Abstract Intravascular large B-cell lymphoma is a rare, non-mass-forming, extranodal large B-cell lymphoma subtype characterized by the presence of tumor cells in the lumens of vessels. It is divided into two major types: classical and Asian. Patients presenting only with skin involvement are mostly female, at a younger age than classical intravascular large B-cell lymphoma patients, and have a better prognosis. Since the diagnosis of cases with isolated skin involvement is difficult, keeping this entity in mind, performing a careful microscopic examination, and applying new, effective treatment regimens will make it possible to achieve better clinical outcomes in these cases.

ABSTRACT

OBJECTIVE@#To evaluate the prognostic value of GELTAMO-IPI for patients with diffuse large B-cell lymphoma (DLBCL).@*METHODS@#The clinical data of 238 newly diagnosed DLBCL patients treated in Shanxi Cancer Hospital from September 2011 to March 2016 were collected retrospectively, the risk stratification and prognostic evaluation of the patients were analyzed according to GELTAMO-IPI. Progression-free survival (PFS) and overall survival (OS) of the patients were analyzed by the Kaplan-Meier method, COX regression analysis was used to compare the risk of death and progress in each risk group. Harrell's C statistics was used to compare the prognostic stratification ability of each model.@*RESULTS@#The 3-year OS rate statistics showed that both IPI and GELTAMO-IPI could distinguish low risk group and Low-intermediate risk group, but the prognosis stratification ability of IPI was better (IPI: HR=5.085, P0.05). GELTAMO-IPI could distinguish High-intermediate risk group from high risk group (GELTAMO-IPI: HR=2.966, P50%). The results of Harrell's C statistics showed the C-index of IPI and GELTAMO-IPI was 0.687 and 0.721 (P<0.001); the C-index of the predicted PFS was 0.672 and 0.700 (P<0.001). It was suggested that the prognostic stratification ability of GELTAM0-IPI be superior to that of IPI, R-IPI, NCCN-IPI.@*CONCLUSION@#GELTAMO-IPI can make a clear distinction between DLBCL patients with different prognosis, especially for high-risk patients, and the prognostic stratification ability of GELTAMO-IPI is significantly better than that of IPI.

ABSTRACT

OBJECTIVE@#To evaluate the efficacy and safety of CHOP regimen based on doxorubicin hydrochloride liposome in the initial treatment of elderly patients with diffuse large B-cell lymphoma (DLBCL).@*METHODS@#Thirty-one patients with DLBCL treated from January 1, 2012 to December 31, 2019 were analyzed retrospectively, their median age was 83 (71-95) years old, and all of them were in Ⅲ-Ⅳ stage, including 17 cases who had international prognostic index (IPI) ≥ 3. The patients were treated with R-CHOP and CHOP regimens based on doxorubicin hydrochloride liposome. The efficacy and safety were evaluated during and after treatment.@*RESULTS@#A total of 219 chemotherapy cycles and 7 median cycles were performed in 31 patients. The overall response (OR) rate and complete remission (CR) rate was 80.7% (25/31) and 61.3% (19/31), respectively, as well as 2 cases (6.5%) stable, 4 cases (12.9%) progressive. The main toxicities were as follows: the incidence of grade Ⅲ -Ⅳ neutropenia was 29% (9/31); two patients (6.5%) developed degree Ⅰ-Ⅱ cardiac events, which were characterized by new degree Ⅰ atrioventricular block; there were no cardiac events requiring emergency treatment and discontinuation of chemotherapy. The 1-year, 2-year and 3-year overall survival rate was 83.9%, 77.4% and 61.3%, respectively. The 1-year, 2-year and 3-year progression-free survival rate was 77.4%, 64.5% and 61.3%, respectively.@*CONCLUSION@#The chemotherapy regimen based on doxorubicin hydrochloride liposome has better efficacy and higher cardiac safety for elderly patients with DLBCL.
