ABSTRACT

El linfoma de Burkitt es una neoplasia altamente agresiva y es un tipo raro de linfoma no Hodgkin localizado. Aunque los niños son los más frecuentemente afectados, en adultos ocurren principalmente durante el embarazo o el puerperio. La mama rara vez constituye la localización primaria del linfoma no Hodgkin. Se presenta un caso de linfoma de Burkitt primario de mama durante el embarazo. Paciente de 37 años con embarazo de 24 semanas quien presentó aumento de volumen difuso de mama derecha. La mama estaba aumentada de tamaño, dolorosa y homogénea con tumoración elástica y firme. La ecografía demostró inflamación difusa con tumoración heterogénea e hipoecoica con contornos ligeramente irregulares, marcadores tumorales estaban normales las pruebas serológicas fueron negativas. La biopsia de la lesión mostró tejido mamario reemplazado por células linfoideas de tamaño mediano con citoplasma basófilo y múltiples vacuolas. Estudios inmunohistoquímicos fueron positivos para el antígeno leucocitario común, CD10, CD20, CD43, Bcl-6. El análisis cromosómico reveló que más del 90 % de las células neoplásicas exhibieron translocación t llevando al diagnóstico final de linfoma de Burkitt de mama. Luego de evaluar las posibilidades terapéuticas y del consentimiento de la paciente se inició tratamiento citostático sistémico. Los linfomas primarios de mama son extremadamente raros. El linfoma de Burkitt primario de la mama es mucho menos común que los otros linfomas. Los métodos de clasificación, detección y tratamiento de esta afección siguen siendo objeto de debates e investigaciones(AU)


The Burkitt's lymphoma is a highly aggressive neoplasm and is a rare type of localized non-Hodgkin lymphoma. Although children are the most frequently affected, in adults they occur mainly during the pregnancy or the puerperium. The breast rarely constitutes the primary location for non-Hodgkin lymphoma. The study of a case of primary Burkitt lymphoma of the breast during pregnancy is presented. This is a 37 year old patient with a 24 week pregnancy who presented a diffuse increase in the volume of the right breast. The breast was enlarged, painful and homogeneous with a firm, elastic mass. The ultrasonography showed diffuse inflammation with a heterogeneous and hypoechoic tumor with slightly irregular contours. The tumor marker values were normal and the serological tests were negative. The biopsy of the lesion showed breast tissue replaced by medium-sized lymphoid cells with basophilic cytoplasm and multiple vacuoles. Immunohistochemically studies were positive for the common leukocyte antigen, CD10, CD20, CD43, Bcl-6. The chromosomal analysis revealed that more than 90 % of neoplastic cells exhibited t translocation leading to the final diagnosis of Burkitt lymphoma of the breast. After evaluating the therapeutic possibilities and the patient's consent, systemic cytostatic treatment was started. Primary breast lymphomas are extremely rare. The primary Burkitt lymphoma of the breast is much less common than other lymphomas. The methods of classification, detection, and the treatment of this condition continue to be the subject of debate and research(AU)

ABSTRACT

METHODS@#From January 2005 to December 2013, 83 patients with refractory/recurrent CD20@*RESULTS@#All the patient achieved complete response. The median follow.up time was 39 months. Both the two groups collected peripheral blood stem cells successfully, and had no difference in hematopoietic reconstitution time. Three patients in treatment group and six patients in control group relapsed and the three year overall survival and EFS in treatment group was significantly higher than that in control group, that is(93.0% vs 73.1%, P=0.037) and (89.5% vs 65.4%, P=0.034), respectively. Subgroup analysis showed that: compared with the treatment group in which using R in the whole courses(before and after transplantation, and collection of stem cells) was superior to the control group in both OS and EFS, with the OS 97% vs 87.5% (P>0.05) and EFS 97% vs 76.2% (P=0.05) respectively. While stratified by the different courses of rituximab, the OS was 88.9% (1-2 courses, 9 cases), 93.1% (3-4 courses, 29 cases), 94.7%(more than 5 courses,19 cases), and EFS was 77.8%, 89.7% and 94.7%, respectively.@*CONCLUSION@#For the patients with refractory/recurrent CD20

ABSTRACT

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.

ABSTRACT

BACKGROUND@#With current chemotherapy treatment, >90% of survival has been obtained for Burkitt lymphoma (BL). In this study, the demographic characteristics and treatment outcomes are presented for 78 children in China with central nervous system-positive (CNS+) BL.@*METHODS@#This retrospective study consecutively enrolled 78 CNS+ BL patients in Beijing Children's Hospital (BCH) from 2007 to 2019 who received the BCH B-cell non-Hodgkin's lymphoma regimen (modified by French-American-British mature lymphoma B-cell 96 [FAB/LMB96] C1 arm ± rituximab). Clinical characteristics, methods of disease detection in the CNS, and outcomes were evaluated. Univariate and multivariate analyses were used to assess prognostic factors.@*RESULTS@#The median age of 65 boys and 13 girls at the time of diagnosis was 5.7 years (ranging from 1 to 14 years). Patients were followed up for a median time of 34 months (ranging from 1 to 72 months). Bone marrow invasion was found in 38 (48.7%) patients. There were 48 (61.5%), 44 (56.4%), and 25 (32%) patients with cranial nerve palsy, intracerebral mass (ICM), and para-meningeal extension, respectively. Abnormal cerebrospinal fluid (CSF) morphology and CSF immunophenotype appeared in 15 (19.2%) and 15 (19.2%) patients, respectively. There were 69 (88.5%) patients treated with chemotherapy combined with rituximab, and nine patients were treated solely with chemotherapy. Finally, five patients died of treatment-related infection, recurrence occurred for 13, and one developed a second tumor. The 3-year overall survival and event-free survival rates were 78.9% ± 4.7% and 71.4% ± 6.0%, respectively. Treatment with chemotherapy only, ICM positivity, and >4 organs involved at diagnosis were independent risk factors.@*CONCLUSIONS@#Rituximab combined with a modified LMB96 regimen has greatly increased the efficacy of treatment for Chinese children with CNS+ BL, and with the continuous collection of outcome data, treatment-related complications are decreasing. For further verification, a large sample multicentre randomized controlled study should be performed to explore a treatment scheme for Chinese children with even greater efficacy.

ABSTRACT

OBJECTIVE@#To investigate the clinical efficacy of high dose methotrexate (HD-MTX), temozolomide (TMZ), and rituximab (R) in the treatment of patients with primary central nervous system lymphoma (PCNSL).@*METHODS@#Clinical data of patients with PCNSL diagnosed and treated in Guangdong Provincial People's Hospital from February 2010 to May 2017 were collected. First, patients were given 6-8 cycles of MTX (3.5 g/m@*RESULTS@#There were 42 patients enrolled in the study, 17 cases in HD-MTX+TMZ group and 25 cases in HD-MTX+TMZ+R group. The median PFS and OS times in HD-MTX+TMZ+R group were 56.7 months and N/A, respectively, while, 7.3 months and 34.7 months in HD-MTX+TMZ group, respectively. In addition, there was no significant difference in median survival between patients who received TMZ maintenance therapy and those who were only actively monitored. During the induction period, all the patients had grade 1-2 nausea and vomiting, while in the consolidation treatment period, no grade 3/4 toxicity was observed.@*CONCLUSION@#The combination of HD-MTX+TMZ+R in the treatment of PCNSL patients shows a definite short-term effect, which can increase the survival rate of the patients. The side effects are mild, and the patients can generally tolerate.

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.

ABSTRACT

OBJECTIVES To evaluate the results of radiotherapy (RT) for follicular lymphoma (FL) under different management scenarios. METHODS We retrospectively assessed consecutive patients with FL who had undergone irradiation between 2010 and 2018. All patients had biopsy-proven FL and were positron emission tomography-staged, although some (35.3%) were reassessed with computed tomography after treatment alone. Rituximab was only available to FL patients after 2016. RESULTS Thirty-four patients were selected, with a mean age at diagnosis of 61.6 years (34-89 years). The median follow-up duration was 49.4 months. Most patients were female (58.8%) and showed good performance on the Eastern Cooperative Oncology Group (ECOG) scale (ECOG 0-55.9%). The mean overall survival (OS) and progression-free survival were 48.7 and 33.6 months, respectively, with four deaths reported. OS rates at 2 and 3 years were 94.1% and 91.2%, respectively. Four patients showed transformation into aggressive lymphomas and underwent rituximab-based systemic treatment. Transformation-free survival was 47.8 months, and all patients with transformed disease were alive at assessment. Five patients had in-field relapse, all of them also relapsed elsewhere, and the mean relapse-free survival time was 40.3 months. No median end points were reached on assessment. CONCLUSION FL is an indolent disease. Our findings show good outcomes for patients treated with radiation, with a low transformation rate and excellent management of relapsed disease. RT is an important part of these results.

ABSTRACT

Abstract Background: Systemic sclerosis (SSc) Is a clinically complex and challenging disease, that leads to skin fibrosis. Its most frequent complication is interstitial lung disease (ILD), which leads to a worse prognosis. In this situation, cyclophosphamide is considered the gold standard for its treatment, despite the controversies regarding its efficacy and toxicity. However, studies using rituximab (RTX) have shown that this drug may be a promising therapeutic option. Objectives: This paper objective was to analyze the scientific evidence on the RTX effects on SSc. Methods: A systematic review (SR) was performed including clinical trials (CTs) on the use of RTX in SSc, published up to May 2020. The studies were identified through systematic searches in bibliographic databases using a predefined search strategy. The following databases were used: PUBMED, SCOPUS, SCIELO, LILACS, SCIENCE DIRECT, WEB OF SCIENCE, COCHRANE, WHOLIS, PAHO and EMBASE. Also, a manual search was performed. The methodological quality of the studies was determined using Jadad scale, Risk of Bias Tool (RoB 2.0) and Risk of Bias in Non-Randomized Studies - of Interventions tool (ROBINS-I). A meta-analysis of the randomized CTs was performed, using Review Manager. Results: Ten CTs were included in this SR. Of these, three were randomized and seven were non-randomized. Five showed a statistically significant improvement in forced vital capacity (FVC) at some time during follow-up. Regarding the skin, eight studies showed statistically significant improvements according toa the modified Rodnan skin score. The meta-analysis found positive effects of RTX in SSc, with a statistical significance for lung disease. Conclusion: Rituximab is a promising strategy for the SSc-associated ILD and cutaneous fibrosis treatment. PROSPERO registration number: CRD42019132018.(AU)

ABSTRACT

Myasthenia gravis (MG) is a heterogeneous disease, and there is no unique therapeutic approach for all patients. In 2013 the Myasthenia Gravis American Foundation (MGFA) panel of experts defined refractory MG as the lack of change or deterioration after the use of corticosteroids and two immunosuppressive agents, in adequate doses and time. We report a 51-years-old female with MG of bulbar predominance, who presented four myasthenic crises in 17 months despite the use of corticosteroids, azathioprine and mycophenolate. The high costs associated with her hospitalizations, as well as severe caloric - protein malnutrition, the need for tracheostomy and gastrostomy support, led us to use rituximab. The patient evolved with an excellent response, free of crises after 30 months. She gained 12 kg of weight, without tracheostomy and gastrostomy, only using pyridostigmine support 4 times a day.

ABSTRACT

Although the first-line rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone regimen (R-CHOP) substantially improved outcomes for patients with diffuse large B-cell lymphoma (DLBCL), 40% of the patients suffered from relapsed/refractory disease and had poor survival outcomes. The detailed mechanism underlying R-CHOP resistance has not been well defined. For this review, we conducted a thorough search for literature and clinical trials involving DLBCL resistance. We discussed DLBCL biology, epigenetics, and aberrant signaling of the B-cell receptor (BCR), phosphatidylinositol 3-kinase (PI3K)/Akt, nuclear factor kappa light chain enhancer of activated B-cells (NF-κB), and the Janus kinase (JAK)/signal transducer and activator of transcription 3 (STAT3) pathways as defining mechanisms of DLBCL heterogeneity and R-CHOP resistance. The cell of origin, double- or triple-hit lymphoma and double-protein-expression, clonal evolution, tumor microenvironment, and multi-drug resistance help to contextualize DLBCL resistance in an (epi)genetically and biologically comparative manner. With better understanding of the biological and molecular landscape of DLBCL, a more detailed classification system and tailored treatments will ideally become available to further improve the prognosis of DLBCL patients.

ABSTRACT

BACKGROUND@#Numerous studies have focused on lymphoma among patients infected with human immunodeficiency virus (HIV). However, little is known about the treatment options and survival rate of lymphoma in the Chinese people living with HIV (PLHIV). Our study aimed to investigate the prognosis and compare outcome of dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (DA-EPOCH-R) with standard cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab(R-CHOP) as front line therapy for PLHIV with diffuse large B-cell lymphoma (DLBCL) receiving modern combined antiretroviral therapy (cART).@*METHODS@#A retrospective analysis evaluating PLHIV with DLBCL was performed in Shanghai Public Health Clinical Center from July 2012 to September 2019. The demographic and clinical data were collected, and overall survival (OS) and progression-free survival (PFS) analyses of patients receiving R-CHOP or DA-EPOCH-R therapy were performed by Kaplan-Meier analysis. Additionally, a Cox multiple regression model was constructed to identify related factors for OS.@*RESULTS@#A total of 54 eligible patients were included in the final analysis with a median follow-up of 14 months (interquartile range [IQR]: 8-29 months). The proportion of high international prognostic index (IPI) patients was much larger in the DA-EPOCH-R group (n = 29) than that in the R-CHOP group (n = 25). The CD4 cell counts and HIV RNA levels were not significantly different between the two groups. The 2-year OS for all patients was 73%. However, OS was not significantly different between the two groups, with a 2-year OS rate of 78% for the DA-EPOCH-R group and 66% for the R-CHOP group. Only an IPI greater than 3 was associated with a decrease in OS, with a hazard ratio of 5.0. The occurrence of grade 3 and 4 adverse events of chemotherapy was not significantly different between the two groups.@*CONCLUSIONS@#Outcomes of R-CHOP therapy do not differ from those of DA-EPOCH-R therapy. No HIV-related factors were found to be associated with the OS of PLHIV in the modern cART era.

ABSTRACT

OBJECTIVE@#To summarize and analyze the clinical characteristics, treatment and prognosis of acute lung injury in patients with diffuse large B-cell lymphoma (DLBCL) after chemotherapy with rituximab chemotherapy, so as to improve the understanding of the disease and guide the clinical treatment.@*METHODS@#Twenty-Six patients with DLBCL were treated with rituximab chemotherapy and developed to acute lung injury in Third Hospital of Peking University from January 2013 to September 2018 were selected. The clinical features, imaging findings, chemotherapy course, therapeutic effect and prognosis were analyzed.@*RESULTS@#The main clinical symptoms of patients were fever, cough and chest tightness, among which 12 patients showed hypoxia and 3 patients showed respiratory failure type I. The mainly manifested chest CT was diffusive glass grinding in both lungs, and some patients were complicated with a small amount of pleural effusion. The onset chemotherapy time was mainly distributed in 2 to 4 courses, the time between the onset of symptoms and the infusion of rituximab was 8 to 49 days. 25 patients shows no obvious limitation in daily life after effective treatment, and 1 patient died of ineffective treatment.@*CONCLUSION@#There are no typical clinical symptoms in the early stage of acute lung injury after rituximab chemotherapy in DLBCL. Early detection and early hormone therapy are very important to achieve good therapeutic effect.
