ABSTRACT

Los LNH constituyen la segunda neoplasia más frecuente en pacientes con VIH. Estas neoplasias están ligadas a la inmunodeficiencia, suelen ser de período de latencia prolongado y más frecuentes en hombres. Más del 95% de estas neoplasias son de fenotipo B, de alto grado de malignidad, extranodales y representan la causa de muerte en un 12% al 16% de los casos. El linfoma no Hodgkin primitivo de mama (LPM) es una entidad infrecuente, que representa el 2,2% de todos los linfomas extranodales y el 0,5% de todas las neoplasias malignas de la mama. Se presenta una mujer con sida y linfoma primario de mama. (AU)


NHL is the second most common neoplasm in patients with HIV. It is linked to immunodeficiency, tends to have a long latency period and is more common in men. More than 95% of these neoplasms are of phenotype B, high-grade, extranodal and are the cause of death in 12% to 16% of cases. Primitive non-Hodgkin lymphoma of the breast is a rare entity, accounting for 2.2% of all extranodal lymphomas and 0.5% of all breast malignancies. A woman with AIDS and primary breast lymphoma is presented. (AU)

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 explore the stem cell collection rate and efficacy and safety of patients aged 70 and below with newly diagnosed multiple myeloma (MM) treated with the VRD (bortezomib, lenalidomide and dexamethasone) regimen followed by autologous stem cell transplantation (ASCT). Methods: Retrospective case series study. The clinical data of 123 patients with newly diagnosed MM from August 1, 2018, to June 30, 2020, at the First Affiliated Hospital of Soochow University and Suzhou Hopes Hematology Hospital, who were eligible for VRD regimen sequential ASCT, were collected. The clinical characteristics, efficacy after induction therapy, mobilization regimen of autologous stem cells, autologous stem cell collection rate, and side effects and efficacy of ASCT were retrospectively analyzed. Results: Of the 123 patients, 67 were males. The median patient age was 56 (range: 31-70) years. Patients with IgG, IgA, IgD, and light-chain types accounted for 47.2% (58/123), 23.6% (29/123), 3.2% (4/123), and 26.0% (32/123) of patients, respectively. In addition, 25.2% (31/123) of patients had renal insufficiency (creatinine clearance rate<40 ml/min). Patients with Revised-International Staging System (R-ISS) Ⅲ accounted for 18.2% (22/121) of patients. After induction therapy, the rates of partial response and above, very-good partial response (VGPR) and above, and complete response (CR)+stringent CR were 82.1% (101/123), 75.6% (93/123), and 45.5% (56/123), respectively. Overall, 90.3% (84/93) of patients were mobilized with cyclophosphamide+granulocyte colony-stimulating factor (G-CSF) and 8 patients with G-CSF or G-CSF+plerixafor due to creatinine clearance rate<30 ml/min and one of them was mobilized with DECP (cisplatin, etoposide, cyclophosphamide and dexamethasone)+G-CSF for progressive disease. The rate of autologous stem cell collection (CD34+cells≥2×106/kg) after four courses of VRD regimen was 89.1% (82/92), and the rate of collection (CD34+cells≥5×106/kg) was 56.5% (52/92). Seventy-seven patients treated with the VRD regimen sequential ASCT. All patients had grade 4 neutropenia and thrombocytopenia. Among the nonhematologic adverse events during ASCT, the highest incidence was observed for gastrointestinal reactions (76.6%, 59/77), followed by oral mucositis (46.8%, 36/77), elevated aminotransferases (44.2%, 34/77), fever (37.7%, 29/77), infection (16.9%, 13/77) and heart-related adverse events (11.7%, 9/77). Among the adverse events, grade 3 adverse events included nausea (6.5%, 5/77), oral mucositis (5.2%, 4/77), vomiting (3.9%, 3/77), infection (2.6%, 2/77), elevated blood pressure after infusion (2.6%, 2/77), elevated alanine transaminase (1.3%, 1/77), and perianal mucositis (1.3%, 1/77); there were no grade 4 or above nonhematologic adverse events. The proportion of patients who achieved VGPR and above after VRD sequential ASCT was 100% (75/75), and the proportion of patients who were minimal residual disease-negative (<10-4 level) was 82.7% (62/75). Conclusion: In patients aged 70 and below with newly diagnosed MM treated with VRD induction therapy, the collection rate of autologous stem cells was good, and good efficacy and tolerability were noted after follow-up ASCT.

ABSTRACT

Objective: To explore the efficacy of immunosuppression intensified conditioning regimen in patients who have strongly positive donor-specific Anti-HLA antibodies (DSAs) and received a haploidentical hematopoietic stem cell transplantation (haplo-HSCT) . Methods: Clinical data of 10 patients with strongly positive pretransplant DSAs (defined as MFI ≥10000) were retrospectively analyzed in this study. All of them received a haplo-HSCT in the Hematology Department of Shanghai Zhaxin Traditional Chinese & Western Medicine Hospital. Results: ① Of all ten patients, three were males, and seven were females, with a median age of 53.5 (36-64) years. Of the 10 patients, three were diagnosed with acute myeloid leukemia, two were myelodysplastic syndromes (MDS), two were chronic myelomonocytic leukemia (CMML), two were in an accelerated phase of chronic myeloid leukemia (CML-AP), and one was primary myelofibrosis (PMF). ② Conditioning regimen consisted of fludarabine (Flu) /busulfan (Bu) combined with whole-body irradiation (TBI) /cyclophosphamide (Cy). ③ On the seventh day after transplantation, the median pretransplant DSA level was MFI 15 999 (10 210-23 417) and 10 787 (0-22 720). ④ Eight patients acquired hematopoietic reconstitution; the median time of neutrophil engraftment was 14 (10-16) days; and 18 (14-20) days for platelet engraftment. After a median follow-up of 12.5 (1.5-27) months, primary graft failure was found in one patient and another with poor graft function. Seven patients remained in a disease remission state, and all were DSA-negative. Conclusions: An intensified immunosuppression conditioning regimen can efficiently decrease the level of donor-specific anti-HLA antibodies (DSAs), leading to good short-term efficacy.

ABSTRACT

OBJECTIVE@#To compare the efficacy of plerixafor (PXF) combined with granulocyte colony-stimulating factor (G-CSF) (PXF+G-CSF) and cyclophosphamide (Cy) combined with G-CSF (Cy+G-CSF) in the mobilization of peripheral blood stem cells (PBSCs) in patients with multiple myeloma (MM).@*METHODS@#The clinical data of 41 MM patients who underwent PBSC mobilization using PXF+G-CSF (18 cases) or Cy+G-CSF (23 cases) in Shanxi Bethune Hospital from January 2019 to December 2021 were retrospectively analyzed, including the count of collected CD34+ cells, acquisition success rate, failure rate, and optimal rate. The correlation of sex, age, disease type, DS staging, ISS staging, number of chemotherapy cycle, disease status before mobilization, and mobilization regimen with the collection results was analyzed, and the adverse reactions, length of hospital stay, and hospitalization costs were compared between the two mobilization regimens.@*RESULTS@#The 41 patients underwent 97 mobilization collections, and the median number of CD34+ cells collected was 6.09 (0-34.07)×106/kg. The acquisition success rate, optimal rate, and failure rate was 90.2%, 56.1%, and 9.8%, respectively. Univariate analysis showed that sex, age, disease type, and disease stage had no significant correlation with the number of CD34+ cells collected and acquisition success rate (P >0.05), but the patients with better disease remission than partial remission before mobilization were more likely to obtain higher CD34+ cell count (P <0.05). The PXF+G-CSF group had a larger number of CD34+ cells and higher acquisition success rate in the first collection than Cy+G-CSF group (both P <0.05), and had lower infection risk and shorter length of hospital stay during mobilization (both P <0.05), but the economic burden increased (P <0.05).@*CONCLUSION@#PXF+G-CSF used for PBSC mobilization in MM patients has high first acquisition success rate, large number of CD34+ cells, less number of collection times, and short length of hospital stay, but the economic cost is heavy.

ABSTRACT

OBJECTIVE@#To evaluate the efficacy and safety of etoposide combined with cyclophosphamide (EC) regimen for mobilization of autologous peripheral blood stem cells (APBSCs) in patients with multiple myeloma (MM).@*METHODS@#The clinical data of 48 MM patients who received APBSC transplantation (APBSCT) in Department of Hematology of the First Affiliated Hospital of Nanchang University from January 2015 to October 2021 were retrospectively analyzed. The mobilization success rate and mobilization optimal rate of EC regimen were counted, and its effect on transplant efficacy, adverse reactions, hematopoietic reconstitution after transplantation, and survival time of MM patients were analyzed.@*RESULTS@#APBSCs were collected on day 14 (10-19) after EC administration. The median of collected CD34+ cells was 6.82 (1.27-22.57)×106/kg, and the median number of apheresis session was 2 (1-4). The mobilization success rate (collecting CD34+ cells≥2×106 cells/kg after completion of apheresis) was 98% (47/48), and mobilization optimal rate (collecting CD34+ cells≥5×106 cells/kg after completion of apheresis) was 71% (34/48). The depth of remission were improved after APBSCT, and the complete remission (CR) rate increased from 45.8% before transplantation to 87.5% after transplantation (P <0.01). There was no transplant-related death, no blood transfusion during mobilization, and no mucositis occurred in the patients. The most common complication was neutropenia, with an incidence of 75.0% (36/48). After transplantation, all the patients successfully achieved hematopoietic reconstitution. The median time to neutrophil engraftment was 10 (9-26) days, and median time to platelet engraftment was 10 (8-33) days. By the end of follow-up, both the median progression-free survival (PFS) and overall survival (OS) time were not reached. The 5-year estimated PFS rate and OS rate was 53.8% and 82.4%, respectively.@*CONCLUSION@#The EC regimen for mobilization of APBSC has a high acquisition success rate and controllable adverse reactions, which can be an effective and safe mobilization regimen in MM patients.

ABSTRACT

Composite lymphoma (CL) involving B-cell lymphoma and T-cell lymphoma is extremely rare. Herein, we report three such cases using immunohistochemistry, flow cytometry, and the next-generation sequencing (NGS) to identify the pathological and molecular characteristics of CL. In the first case, the patient was admitted to hospital for generalized pruritic maculopapular rash over the whole body. An excisional biopsy of the skin lesions showed T-cell lymphoma. At the same time, the staging bone marrow (BM) biopsy revealed a diffuse large B-cell lymphoma (DLBCL). After R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) therapies, the patient produced a good response with substantial dissipation of the rashes and relief of skin. The other two patients were admitted to hospital due to lymphadenopathy and were diagnosed with DLBCL and follicular lymphoma (FL) after core needle biopsy of lymph nodes, BM biopsy, BM aspiration, and flow cytometry. Following R-CHOP and R-COP (rituximab, cyclophosphamide, vincristine, and prednisone) therapies, they achieved complete remission unconfirmed (CRu) and complete remission (CR). However, one or two years later, they suffered a relapse of lymphadenopathy. The shocking fact was that re-biopsy of lymphadenopathy revealed peripheral T-cell lymphoma (PTCL) and angioimmunoblastic T-cell lymphoma (AITL). NGS findings identified DNA methyltransferase 3a (DNMT3a), isocitrate dehydrogenase 2 (IDH2), Ras homolog gene family, member A (RHOA), splicing factor 3B subunit 1 (SF3B1), and tumor protein p53 (TP53) mutations. After immunochemotherapy, these patients achieved CRu and CR again. Nevertheless, they suffered a second relapse of T-cell lymphoma. Finally, they died due to progression of disease. We found that the occurrence of CL is associated with Epstein-Barr virus infection and DNMT3a, IDH2, and TP53 mutations, and the prognosis of the disease is closely related to the T-cell lymphoma components.

ABSTRACT

El término miocarditis hace referencia a una inflamación del miocardio, que puede tener diversas causas (infecciones, tóxicos, enfermedades autoinmunes). Su diagnóstico es desafiante debido al gran espectro de presentaciones clínicas que puede adoptar, muchas veces imitando patologías más prevalentes como el infarto agudo de miocardio. La miocarditis asociada a enfermedades autoinmunes es poco frecuente, y la importancia de reconocerla radica en que el diagnóstico e inicio temprano del tratamiento son cruciales para mejorar su pronóstico. Presentamos aquí un caso clínico de una perimiocarditis lúpica.


Myocarditis refers to an inflammation of the myocardium, which can have various causes (infections, toxic substances, autoimmune diseases). Its diagnosis is challenging due to the wide spectrum of clinical presentations, often mimicking more prevalent pathologies such as acute myocardial infarction. Myocarditis associated with autoimmune diseases is rare, and the importance of recognizing is that early diagnosis and initiation of treatment are crucial to improve its prognosis. We present here a clinical case of lupus perimyocarditis.

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: To evaluate the efficacy and toxicity profiles of idarubicin, cytarabine, and cyclophosphamide (IAC) in relapse/refractory acute myeloid leukemia (AML) . Methods: This study was a prospective, randomized controlled clinical trial with the registration number NCT02937662. The patients were randomly divided into two groups. The experimental group was treated with an IAC regimen, and the regimen of the control group was selected by doctors according to medication experience. After salvage chemotherapy, allogeneic hematopoietic stem cell transplantation (allo-HSCT) was conducted as far as possible according to the situation of the patients. We aimed to observe the efficacy, safety, and toxicity of the IAC regimen in relapse/refractory AML and to explore which is the better regimen. Results: Forty-two patients were enrolled in the clinical trial, with a median age of 36 years (IAC group, 22 cases and control groups, 20 cases) . ①The objective response rate was 71.4% in the IAC group and 40.0% in the control group (P=0.062) ; the complete remission (CR) rate was 66.7% in the IAC group and 40.0% in the control group (P=0.121) . The median follow-up time of surviving patients was 10.5 (range:1.7-32.8) months; the median overall survival (OS) was 14.1 (range: 0.6-49.1) months in the IAC group and 9.9 (range: 2.0-53.8) months in the control group (P=0.305) . The 1-year OS was 54.5% (95%CI 33.7%-75.3%) in the IAC group and 48.2% (95%CI 25.9%-70.5%) in the control group (P=0.305) , with no significant difference between these two regimens. ②The main hematologic adverse events (AEs) were anemia, thrombocytopenia, and neutropenia. The incidence of grade 3-4 hematologic AEs in the two groups was 100% (22/22) in the IAC group and 95% (19/20) in the control group. The median time of neutropenia after chemotherapy in the IAC group and control group was 20 (IQR: 8-30) and 14 (IQR: 5-50) days, respectively (P=0.023) . ③The CR rate of the early relapse (relapse within 12 months) group was 46.7% and that of the late relapse (relapse after 12 months) group was 72.7% (P=0.17) . The median OS time of early recurrence was 9.9 (range:1.7-53.8) months, and that of late recurrence patients was 19.3 (range: 0.6-40.8) months (P=0.420) , with no significant differences between the two groups. The 1-year OS rates were 45.3% (95%CI 27.2%-63.3%) and 66.7% (95%CI 40.0%-93.4%) , respectively (P=0.420) . Survival analysis showed that the 1-year OS rates of the hematopoietic stem cell transplantation group and non-hematopoietic stem cell transplantation group were 87.5% (95%CI 71.2%-100%) and 6.3% (95%CI 5.7%-18.3%) , respectively. The OS rate of the hematopoietic stem cell transplantation group was significantly higher than that of the non-hematopoietic stem cell transplantation group (P<0.001) . Conclusion: The IAC regimen is a well-tolerated and effective regimen in relapsed/refractory AML; this regimen had similar efficacy and safety with the regimen selected according to the doctor's experience for treating relapsed/refractory AML. For relapsed/refractory patients with AML, allogeneic hematopoietic stem cell transplantation should be attempted as soon as possible to achieve long-term survival.

ABSTRACT

OBJECTIVE@#To investigate the therapeutic effects of total saponins from Panax notognseng (PNS) combined with cyclophosphamide (CTX) in mice bearing hepatocellular carcinoma H22 cell xenograft.@*METHODS@#We examined the effects of treatment with different concentrations of PNS on H22 cell proliferation for 24 to 72 h in vitro using CCK8 colorimetric assay. Annexin V/PI double fluorescence staining was used to detect the effect of PNS on apoptosis of H22 cells. Mouse models bearing H22 cell xenograft were established and treated with CTX (25 mg/kg), PNS (120, 240 or 480 mg/kg), alone or in combinations. After treatments for consecutive 10 days, the mice were euthanized for examinations of carbon clearance ability of the monocytes and macrophages, splenic lymphocyte proliferation, tumor necrosis factor (TNF-α), interleukin-2 (IL-2), serum hemolysin antibody level, blood indicators, and the tumor inhibition rate.@*RESULTS@#Treatment with PNS concentration-dependently inhibited the proliferation and significantly promoted apoptosis of cultured H22 cells (P < 0.01). In the tumor-bearing mouse models, PNS alone and its combination with CTX both resulted in obvious enhancement of phagocytosis of the monocyte-macrophages, stimulated the proliferation of splenic lymphocytes, promoted the release of TNF-α and IL-2 and the production of serum hemolysin antibody, and increased the number of white blood cells, red blood cells and lymphocytes in the peripheral blood. Treatment with 480 mg/kg PNS combined with CTX resulted in a tumor inhibition rate of 83.28% (P < 0.01) and a life prolonging rate of 131.25% in the mouse models (P < 0.05).@*CONCLUSION@#PNS alone or in combination with CTX can improve the immunity and tumor inhibition rate and prolong the survival time of H22 tumor-bearing mice.

ABSTRACT

OBJECTIVE@#To analyze clinical response of the Rituximab-based chemotherapy and prognostic features in patients with primary gastric diffuse large B-cell lymphoma (PGDLBCL).@*METHODS@#From June 2008 to December 2020, the data of 53 PGDLBCL patients were analyzed retrospectively.@*RESULTS@#The median age was 46(25-77) years old in 53 patients including 35 males and 18 females. Stomachache is the most common symptom. The diagnosis were confirmed in 47 patients by endoscopic biopsy and 6 patients by surgery. Twenty-six patients had Ⅰ/Ⅱ1 stage (Lugano staging system) disease and 27 cases had II2/IV stage disease. All patients were treated with chemotherapy, including RCHOP (25/53) and R-DA-EPOCH (28/53). Complete remission rate was 79.2%(42/53). The 3-year and 5-year overall survival (OS) rates were 77.4% and 69.8%. Univariate analysis showed that lactate dehydrogenase(LDH), Lugano stage and lesion size affected OS. Multivariate Cox regression analysis revealed that IPI score and Lugano stage were independent prognosis risk factors affecting OS. The patients in the R-DA-EPOCH group presented better survival outcomes than those in the RCHOP group with late stage (P5-year OS=0.035).@*CONCLUSION@#Rituximab in combination with chemotherapy is the backbone of therapy for PGDLBCL. IPI score and Lugano stage are independent prognosis risk factors affecting OS of PGDLBCL. R-DA-EPOCH can be superior to R-CHOP as a first-line regimen in PGDLBCL patients with late stage.

ABSTRACT

Objective: To investigate the pathological characteristics and clinical prognosis of nodular sclerosis grade 2 of classic Hodgkin's lymphoma (cHL-NS2) in our cancer center. Methods: A retrospective collection of 23 cases of cHL-NS2 admitted in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from July 2008 to April 2019 was performed. Fifty-five cases of nodular sclerosis grade 1 of classical Hodgkin's lymphoma (cHL-NS1) during the same period were selected as control group. Survival curves were plotted using the Kaplan-Meier method, and Cox regression model was used to analyze the influencing factors for survival. Results: The median age of 23 cases of cHL-NS2 was 30 years old. Five cases had extra nodal invasion, and 19 cases were Ⅰ-Ⅱ stage based on Ann Arbor system. The pathological morphology of cHL-NS2 showed that the lymph node structure was completely destroyed and was divided into nodules by thick collagen. The tumor cells in the nodules were abundant and proliferated in sheets. The boundaries between the tumor cells were not clear. The incidence of tumor necrosis in cHL-NS2 was 43.5% (10/23), which was significantly higher than 18.2% (10/55) in cHL-NS1 (P=0.040). The 3-year progression-free survival (PFS) rate of patients in the cHL-NS2 group was 58.1%, which was significantly lower than 89.7% in the cHL-NS1 group (P=0.002). In all of 78 cases, the 3-year PFS rate of patients who did not obtain complete response (CR) was 67.1%, which was significantly lower than 92.2% in patients who achieved CR (P=0.030). Multivariate Cox regression analysis demonstrated that both cHL-NS2 and failure to obtain CR by first-line treatment were independent indicators for short PFS time (P<0.05). Conclusions: In cHL-NS2, the morphology of tumor cells are diverse, and tumor necrosis can be easily found. Under the current first-line treatments of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) or bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP), cHL-NS2 is an independent indicator for worse PFS.

ABSTRACT

ABSTRACT There have been significant improvements in therapeutic options for relapsed multiple myeloma (MM) over the past two decades, with many novel agents including proteasome inhibitors, immunomodulatory agents, and more recently monoclonal antibodies demonstrating efficacy in this setting. However, there is a paucity of real-world data comparing outcomes seen in patients treated with novel agents as opposed to older agents. We report a historical single center cohort of patients diagnosed with myeloma between the years 1991-2012 in order to explore possible differences in outcomes. A total of 139 patients who underwent stem cell transplantation were included in our study. In our study, 88 patients were treated with cyclophosphamide and steroids alone at relapse whereas 51 patients were treated with Len-Dex. In the multivariate analysis, TTNT was shorter for patients who received Cyclo compared to Len-Dex (HR = 1.74; 95% CI, 1.01-2.99; p = 0.04); however, we could not detect an overall survival benefit (HR = 1.20; 95% CI 0.63-2.29; p = 0.57). Adverse event rates were similar in the two groups. In this retrospective single center analysis, Len-Dex was associated with longer TTNT compared with Cyclo at first relapse following autoSCT in MM; however its effect on overall survival in this setting was less clear.

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

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.
