Subcutaneous Panniculitis-like T Cell Lymphoma Diagnosed with a Slowly Progressive Course: A Case Report.

Panniculitis is an inflammation that occurs in subcutaneous adipose tissue. Panniculitis includes physical panniculitis (e.g., traumatic) and infectious panniculitis (e.g., bacterial, fungal, subcutaneous panniculitis-like T cell lymphoma [SPCTL], etc.). Accurate diagnosis is crucial due to similar clinical presentation of all types of panniculitis. Here, we report a case of SPCTL which was initially diagnosed with traumatic panniculitis. A 15-year-old male patient was admitted to a previous hospital due to a progressively enlarged right flank and inguinal mass after an abdominal bruise. He was initially diagnosed with traumatic panniculitis, but the mass expanded throughout the chest and abdomen accompanied by a fever of over 11 months. Computed tomography (CT) revealed a subcutaneous mass in the anterior chest and abdominal wall. Fludeoxyglucose F18 (FDG) uptake was observed at those lesions using FDG-positron emission tomography (PET). A biopsy of the mass lesion was performed, during which SPCTL was diagnosed based on pathological examination. He was initially treated with prednisolone and cyclosporine A for two weeks. His fever went down, but subcutaneous mass in the chest and abdominal wall persisted. Therefore, he received a cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen. After 6 courses of CHOP, CT revealed no disease evidence. He remained in complete remission at 30 months of therapy.

Combination Targeted Therapy in Relapsed Diffuse Large B-Cell Lymphoma.

BACKGROUND: The identification of oncogenic mutations in diffuse large B-cell lymphoma (DLBCL) has led to the development of drugs that target essential survival pathways, but whether targeting multiple survival pathways may be curative in DLBCL is unknown. METHODS: We performed a single-center, phase 1b-2 study of a regimen of venetoclax, ibrutinib, prednisone, obinutuzumab, and lenalidomide (ViPOR) in relapsed or refractory DLBCL. In phase 1b, which included patients with DLBCL and indolent lymphomas, four dose levels of venetoclax were evaluated to identify the recommended phase 2 dose, with fixed doses of the other four drugs. A phase 2 expansion in patients with germinal-center B-cell (GCB) and non-GCB DLBCL was performed. ViPOR was administered every 21 days for six cycles. RESULTS: In phase 1b of the study, involving 20 patients (10 with DLBCL), a single dose-limiting toxic effect of grade 3 intracranial hemorrhage occurred, a result that established venetoclax at a dose of 800 mg as the recommended phase 2 dose. Phase 2 included 40 patients with DLBCL. Toxic effects that were observed among all the patients included grade 3 or 4 neutropenia (in 24% of the cycles), thrombocytopenia (in 23%), anemia (in 7%), and febrile neutropenia (in 1%). Objective responses occurred in 54% of 48 evaluable patients with DLBCL, and complete responses occurred in 38%; complete responses were exclusively in patients with non-GCB DLBCL and high-grade B-cell lymphoma with rearrangements of MYC and BCL2 or BCL6 (or both). Circulating tumor DNA was undetectable in 33% of the patients at the end of ViPOR therapy. With a median follow-up of 40 months, 2-year progression-free survival and overall survival were 34% (95% confidence interval [CI], 21 to 47) and 36% (95% CI, 23 to 49), respectively. CONCLUSIONS: Treatment with ViPOR was associated with durable remissions in patients with specific molecular DLBCL subtypes and was associated with mainly reversible adverse events.

Comparison of tacrolimus with or without prednisone therapy in primary membranous nephropathy: a retrospective clinical study.

Previous studies showed tacrolimus monotherapy and dual therapy with tacrolimus and prednisone as effective treatment modalities in managing membranous nephropathy. However, few studies have compared these therapeutic regimens. The patients were divided into two groups based on the treatment regimen: (1) tacrolimus and prednisone dual therapy (T + P group, n = 67) treatment group; and (2) tacrolimus monotherapy (T group, n = 65) or the control group. Propensity matching method and subgroup analysis to eliminate the bias in the relationship between the treatment regimen and the outcomes. The mean remission times were 20.33 ± 2.75 weeks at T group and 9.50 ± 1.81 weeks at T + P group. The T group had a remission rates of 73.33, 76.66 and 66.66% at 12weeks, 24weeks and 48weeks, while the T + P group had a remission rate of 81.66, 86.66, 91.66%; At the follow-up of 48 weeks, the relapse rate for the T group was 21.66%, and that for the T + P group was 5%. The anti-PLA2R ab is positive and therapy may be the independent risk factors for predicting remission. Tacrolimus and low-dose prednisone dual therapy is efficacious in managing MN and lowers the recurrence rate in clinical practice.

[Primary renal triple expressor DLBCL treated with chemotherapy under continuous hemodialysis and filtration support].

A 69-year-old woman was previously treated with antibiotics for suspected pyelonephritis due to fever but showed limited improvement. Contrast-enhanced CT revealed heterogeneous areas of decreased contrast enhancement in both kidneys, along with an elevated soluble level of the IL-2 receptor (5,090 U/ml), and thus the patient was referred to our department for further evaluation. A percutaneous renal biopsy performed due to suspected malignant lymphoma confirmed lymphoma cell infiltration into the renal interstitium. Immunohistochemical staining was positive for MYC/BCL2/BCL6, leading to the diagnosis of stage IVB primary renal triple expressor diffuse large B cell lymphoma (DLBCL). Due to acute kidney injury, continuous hemodiafiltration (CHDF) was initiated, followed by rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy. The patient's renal function improved rapidly, and complete response was achieved after six cycles of R-CHOP. Although DLBCL is a common lymphoma, the primary renal subtype is extremely rare and poses both diagnostic and therapeutic challenges. This case highlights the potential clinical implications of combining CHDF with chemotherapy to achieve complete response despite an initial poor prognosis based on the patient's overall clinical condition and pathology.

Brentuximab vedotin therapy followed by autologous peripheral stem cell transplantation as a viable treatment option for an older adult with transformed lymphoma: a case report and literature review.

This report presents a case involving a woman aged >65 years who had been diagnosed with marginal zone lymphoma 3 years prior. The patient was hospitalized with enlarged inguinal lymph nodes, and pathological examination revealed that the lymphoma had transformed into diffuse large B-cell lymphoma. After two cycles of brentuximab vedotin in combination with rituximab, cyclophosphamide, doxorubicin, and prednisone (BV-R-CHP) chemotherapy, the patient achieved complete remission. This treatment was followed by autologous hematopoietic stem cell transplantation and lenalidomide maintenance therapy. At the last follow-up, the patient had been in continuous remission for 24 months. This case study suggests that the utilization of BV and R-CHP in conjunction can result in rapid remission, and it can be followed by autologous hematopoietic stem cell transplantation and maintenance therapy with lenalidomide. This treatment approach exhibits potential as a viable option for older individuals with transformed lymphoma.

[The Reduction of CD4+ T Lymphocytes after the Treatment of Follicular Lymphoma with the Bendamustine Containing Regimen May Predict the Occurrence of Infection and Efficacy].

OBJECTIVE: To investigate the effectiveness, safety, and related prognostic factors of the treatment of follicular lymphoma (FL) with a regimen containing Bendamustine. METHODS: The clinical data of 129 FL patients who were treated with Bendamustine containing regimen were collected from January 1,2020 to October 30,2022 in the Hematology Department of Lianyungang Second People's Hospital and Jiangsu Provincial People's Hospital. The patients were divided into three groups: Bendamustine plus Rituximab (BR), Bendamustine plus Obinutuzumab (GB), Rituximab + Cyclophosphamide + Epirubicin / Doxorubicin + Vindesine + Prednisone (R-CHOP). The efficacy, safety and related prognostic factors of the treatment of FL with a regimen based on Bendamustine were retrospectively analyzed. RESULTS: The ORR was 98% for the BR group, 94% for the GB group, and 72.3% for the R-CHOP group, while the CR rate was 61.2%,70% and 40.4%, respectively. The ORR and CR rates of the R-CHOP group were statistically different from those of the BR group and GB group (P < 0.05). The 3-year PFS rate of the BR group, GB group, and R-CHOP group was 89.6%, 90.9%, 48.9%, respectively. There was a statistically significant difference in 3-year PFS between the R-CHOP group, BR group, and GB group (P < 0.05), while there was no statistically significant difference in 3-year OS（P ＞0.05）. Hematological adverse reactions were mainly bone marrow suppression. Lymphocytes and CD4+T lymphocytes decreased to the lowest level about 6 months after treatment, and the incidence of lymphopenia in BR group and GB group was higher than that in R-CHOP group, with a statistical difference (P < 0.05). The higher incidence of non-Hematological adverse reactions were pulmonary infection, EB virus infection, hepatitis B virus reactivation, and gastrointestinal reactions without statistical difference in 3 groups (P >0.05), and were all controllable. The Receiver operating characteristic of CD4+T lymphocyte count showed that AUC of BR group was 0.802, and the critical value was 258/uL; AUC of GB group was 0.754 with a critical value of 322/uL. CONCLUSION: The treatment of FL with the Bendamustine containing regimen has good efficacy and controllable adverse reactions, but lymphocytopenia was significant after treatment, and the curative efficacy in combination with various CD20 monoclonal antibodies was different. The lowest CD4+T lymphocyte count can be used as a predictive factor for the occurrence of infection and efficacy of the Bendamustine containing regimen for FL.

[A Retrospective Study of R±DHAX Regimen versus R-CHOP Regimen First-Line Treatment of Elderly Patients with Newly Diagnosed Diffuse Large B-Cell Lymphoma].

OBJECTIVE: To investigate the clinical efficacy and prognosis of Rituximab combined with DHAX and CHOP regimen in the first-line treatment of elderly patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL). METHODS: A total of 36 elderly patients with DLBCL who were admitted and treated with 3 of more courses of treatment from August 2011 to August 2021 were retrospectively analyzed, and they were divided into rituximab±DHAX (R±DHAX) regimen group (18 cases) and rituximab±CHOP (R-CHOP) regimen group (18 cases) according to the treatment plan, and clinical features, efficacy and survival of the patients were observed. RESULTS: Compared with R-CHOP group, patients of the R±DHAX group were older, and had worse performance status and higher IPI score, the differences between two groups in age, ECOG score and IPI score were statistically significant ( P =0.005 P =0.018, P =0.035), but there were no significant differences beween two groups in gender, whether there were B symptoms, whether LDH was elevated, whether there was extranodal involvement, cell origin, bone marrow infiltration, and whether rituximab was combined ( P =0.738, P =1, P =0.315, P =0.305, P =0.413, P =0.177, P =0.711, P =0.229). The efficacy could be evaluated in 36 cases, including CR 14 (38.9%), PR 17 (47.2%), PD 5 (13.9%), and ORR of 86.1% (31/36). There were no statistically significant differences in CRï¼»(27.8%（5/18） vs 50.0%（9/18）; P >0.05ï¼½ and PR ï¼»44.4%（8/18） vs 50.0%（9/18）; P >0.05ï¼½ of R±DHAX group and R-CHOP group, there was statistically significant difference in ORRï¼»72.2%（13/18） vs 100.0%（18/18）; P =0.045ï¼½ between two groups. The 1-year OS of R±DHAX group and R-CHOP group was (38.9±11.5%)% and (94.4±7.4%)%, respectively, 2-year OS was (16.7±8.8)% and (72.2±10.6)%, respectively, and the differences between two groups were statistically significant ( P =0.001, P =0.002). The median survival time in the R±DHAX group was 11 months(95%CI :8.9-13.1), and the median survival time in the R-CHOP group was not reached, and there was a statistically significant difference between the groups (P < 0.001). CONCLUSION: For elderly DLBCL patients, R±DHAX may not be superior to R-CHOP in OS, and ECOG score, IPI score and age may affect the survival of elderly DLBCL patients. However, R±DHAX regimen is safe, tolerable and has a certain efficacy, which can be used as one of the clinical treatment options for elderly DLBCL.

Isolated central nervous system relapse in two adolescents with primary mediastinal large B-cell lymphoma after treatment with R-DA-EPOCH.

The addition of rituximab to standard regimens for primary mediastinal large B-cell lymphoma (PMBCL) has significantly improved overall survival. However, the optimal management of isolated central nervous system (CNS) relapse and role of CNS prophylaxis remains undefined. We present cases of two adolescents with PMBCL who developed isolated CNS relapses. While isolated CNS relapse may be managed with high-dose chemotherapy and autologous stem cell transplant with or without CNS radiotherapy, review of these cases and the literature highlight the need for further work to define risk factors for CNS relapse, and identify patients who may benefit from CNS prophylaxis.

Diffuse Large B-Cell Lymphoma With Cardiac Invasion Presented as Acute Myocardial Infarction and Left Ventricular Hypertrophy: A Case Report.

Primary cardiac lymphoma is an exceedingly rare malignant tumor, with diffuse large B-cell lymphoma (DLBCL) being the most prevalent histological subtype. This disease has non-specific clinical manifestations, making early diagnosis crucial. However, DLBCL diagnosis is commonly delayed, and its prognosis is typically poor. Herein, we report the case of a 51-year-old male patient with DLBCL who presented with recurrent chest tightness for 4 months as the primary clinical symptom. The patient was admitted to the hospital and diagnosed with acute myocardial infarction and left ventricular hypertrophy with heart failure. Echocardiography revealed a progression from left ventricular thickening to local pericardial thickening and adhesion in the inferior and lateral walls of the left ventricle. Finally, pathological analysis of myocardial biopsy confirmed the diagnosis of DLBCL. After treatment with the R-CHOP chemotherapy regimen, the patient's chest tightness improved, and he was discharged. After 2 months, the patient succumbed to death owing to sudden ventricular tachycardia, ventricular fibrillation, and decreased blood pressure despite rescue efforts. Transthoracic echocardiography is inevitable for the early diagnosis of DLBCL, as it can narrow the differential and guide further investigations and interventions, thereby improving the survival of these patients.

Testing novel strategies for patients hospitalised with HIV-associated disseminated tuberculosis (NewStrat-TB): protocol for a randomised controlled trial.

BACKGROUND: HIV-associated tuberculosis (TB) contributes disproportionately to global tuberculosis mortality. Patients hospitalised at the time of the diagnosis of HIV-associated disseminated TB are typically severely ill and have a high mortality risk despite initiation of tuberculosis treatment. The objective of the study is to assess the safety and efficacy of both intensified TB treatment (high dose rifampicin plus levofloxacin) and immunomodulation with corticosteroids as interventions to reduce early mortality in hospitalised patients with HIV-associated disseminated TB. METHODS: This is a phase III randomised controlled superiority trial, evaluating two interventions in a 2 × 2 factorial design: (1) high dose rifampicin (35 mg/kg/day) plus levofloxacin added to standard TB treatment for the first 14 days versus standard tuberculosis treatment and (2) adjunctive corticosteroids (prednisone 1.5 mg/kg/day) versus identical placebo for the first 14 days of TB treatment. The study population is HIV-positive patients diagnosed with disseminated TB (defined as being positive by at least one of the following assays: urine Alere LAM, urine Xpert MTB/RIF Ultra or blood Xpert MTB/RIF Ultra) during a hospital admission. The primary endpoint is all-cause mortality at 12 weeks comparing, first, patients receiving intensified TB treatment to standard of care and, second, patients receiving corticosteroids to those receiving placebo. Analysis of the primary endpoint will be by intention to treat. Secondary endpoints include all-cause mortality at 2 and 24 weeks. Safety and tolerability endpoints include hepatoxicity evaluations and corticosteroid-related adverse events. DISCUSSION: Disseminated TB is characterised by a high mycobacterial load and patients are often critically ill at presentation, with features of sepsis, which carries a high mortality risk. Interventions that reduce this high mycobacterial load or modulate associated immune activation could potentially reduce mortality. If found to be safe and effective, the interventions being evaluated in this trial could be easily implemented in clinical practice. TRIAL REGISTRATION: ClinicalTrials.gov NCT04951986.

A randomised trial of oral prednisone for cystic fibrosis pulmonary exacerbation treatment.

BACKGROUND: Elevated markers of systemic and pulmonary inflammation are associated with failure to recover lung function following pulmonary exacerbations in people with cystic fibrosis (pwCF). Our aim was to determine whether adjuvant oral prednisone treatment would improve recovery of forced expiratory volume in 1 s (FEV1) % pred in CF pulmonary exacerbations not responding to antibiotic therapy. METHODS: This was a randomised, double-blind, placebo-controlled trial in pwCF treated with intravenous antibiotics for a pulmonary exacerbation. At day 7, those who had not returned to >90% baseline FEV1 % pred were randomised to adjuvant prednisone 1 mg·kg-1 twice daily (maximum 60 mg·day-1) or placebo for 7 days. The primary outcome was the difference in proportion of subjects who recovered >90% baseline FEV1 % pred at day 14 of i.v. antibiotic therapy. RESULTS: 173 subjects were enrolled, with 76 randomised. 50% of subjects in the prednisone group recovered baseline FEV1 on day 14 compared with 39% of subjects in the placebo group (difference of 11%, 95% CI -11-34%; p=0.34). The mean±sd change in FEV1 % pred from day 7 to day 14 was 6.8±8.8% predicted in the prednisone group and 4.6±6.9% predicted in the placebo group (mean difference 2.2% predicted, 95% CI -1.5-5.9%; p=0.24). Time to subsequent exacerbation was not prolonged in prednisone-treated subjects (hazard ratio 0.83, 95% CI 0.45-1.53; p=0.54). CONCLUSIONS: This study failed to detect a difference in FEV1 % pred recovery between adjuvant oral prednisone and placebo treatment in pwCF not responding at day 7 of i.v. antibiotic therapy for pulmonary exacerbations.

[Clinical analysis of 18 children with aggressive mature B-cell lymphoma after liver transplantation].

Objective: To summarize the clinical characteristics, prognostic factors and treatment outcomes of childhood aggressive mature B-cell lymphoma after liver transplantation. Methods: This retrospective study included 18 children with newly diagnosed aggressive mature B-cell lymphoma after liver transplantation and treated from June 2018 to June 2022 in the Department of Hematology and Oncology of Shanghai Children's Medical Center, Shanghai Jiao Tong University School of Medicine. Clinical characteristics, treatment and outcomes of patients at last evaluation were analyzed. Overall survival (OS) and event free survival (EFS) rates were calculated by Kaplan-Meier method and Log-Rank analysis was performed to find factors of poor prognosis. Results: Among all 18 patients, there were 6 males and 12 females, and the age of onset was 40 (35, 54) months. The interval from transplant to tumor diagnosis was 21 (17, 35) months and 5 patients had early onset disease (<1 year since transplant). Seventeen patients had abdominal lesions. Diarrhea, vomiting and abdominal masses were the main clinical manifestations. All patients were Epstein-Barr virus (EBV) related posttransplant lymphoproliferative disorders (PTLD). One patient received individualized therapy due to critical sick at diagnosis, and the remaining 17 patients received CP (cyclophosphamide, methylprednisolone plus rituximab) and (or) modified EPOCH (prednisone, etoposide, doxorubicin, vincristine, cyclophosphamide plus rituximab) regimens. Of all 18 patients, 15 cases got complete response, 2 cases got partial response, 1 patient died of severe infection. The 2-year OS and EFS rates of 18 patients were (94±5)% and (83±8)%, respectively. None of age, gender or early onset disease had effect on OS and EFS rates in univariate analysis (all P>0.05). Conclusions: The symptoms of PTLD were atypical. Close surveillance of EBV-DNA for patients after liver transplantation was crucial to early stage PTLD diagnosis. CP or modified EPOCH regimen was efficient for pediatric patients with aggressive mature B cell lymphoma after liver transplantation.

Efficacy and safety of netupitant/palonosetron in preventing nausea and vomiting in diffuse large B cell lymphoma patients undergoing R-CHOP chemotherapy.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma, for which cyclophosphamide, doxorubicin, vincristine, and prednisone with rituximab(R-CHOP) is one of the standard regimens. Given that R-CHOP is highly emetogenic, chemotherapy-induced nausea and vomiting (CINV) prevention is clinically important. However, there is a paucity of studies focusing on these patients. This study aimed to ascertain the effectiveness of an oral fixed-dose combination of netupitant and palonosetron (NEPA) in preventing CINV in patients with DLBCL undergoing first-line R-CHOP chemotherapy. Seventy patients were enrolled in this single-center prospective non-comparative study conducted between November 2020 and May 2023 in South Korea. NEPA was administered 1 h prior to chemotherapy initiation on day 1. The primary endpoint of the study was the complete response rate (no emesis, and no rescue medication) during the acute, delayed, and overall phases, which were assessed over a period of 120 h post-chemotherapy. The complete response rates for NEPA were 90.0% [95% CI 80.5, 95.9] for the acute phase, 85.7% [95% CI 75.3, 92.9] for the delayed phase, and 84.3% [95% CI 73.6, 91.9] for the overall phase, with no-emesis rates (acute: 97.1% [95% CI 97.1, 99.7], delayed: 95.7% [95% CI 88.0, 99.1], overall: 92.9% [95% CI 84.1, 97.6]). NEPA was well tolerated with no severe treatment-emergent adverse events. NEPA exhibited substantial efficacy in mitigating CINV in DLBCL patients undergoing R-CHOP chemotherapy, demonstrating high CR and no-emesis rates, and favorable safety profiles.

Ibrutinib combined with immunochemotherapy with or without autologous stem-cell transplantation versus immunochemotherapy and autologous stem-cell transplantation in previously untreated patients with mantle cell lymphoma (TRIANGLE): a three-arm, randomised, open-label, phase 3 superiority trial of the European Mantle Cell Lymphoma Network.

BACKGROUND: Adding ibrutinib to standard immunochemotherapy might improve outcomes and challenge autologous stem-cell transplantation (ASCT) in younger (aged 65 years or younger) mantle cell lymphoma patients. This trial aimed to investigate whether the addition of ibrutinib results in a superior clinical outcome compared with the pre-trial immunochemotherapy standard with ASCT or an ibrutinib-containing treatment without ASCT. We also investigated whether standard treatment with ASCT is superior to a treatment adding ibrutinib but without ASCT. METHODS: The open-label, randomised, three-arm, parallel-group, superiority TRIANGLE trial was performed in 165 secondary or tertiary clinical centres in 13 European countries and Israel. Patients with previously untreated, stage II-IV mantle cell lymphoma, aged 18-65 years and suitable for ASCT were randomly assigned 1:1:1 to control group A or experimental groups A+I or I, stratified by study group and mantle cell lymphoma international prognostic index risk groups. Treatment in group A consisted of six alternating cycles of R-CHOP (intravenous rituximab 375 mg/m2 on day 0 or 1, intravenous cyclophosphamide 750 mg/m2 on day 1, intravenous doxorubicin 50 mg/m2 on day 1, intravenous vincristine 1·4 mg/m2 on day 1, and oral prednisone 100 mg on days 1-5) and R-DHAP (or R-DHAOx, intravenous rituximab 375 mg/m2 on day 0 or 1, intravenous or oral dexamethasone 40 mg on days 1-4, intravenous cytarabine 2 × 2 g/m2 for 3 h every 12 h on day 2, and intravenous cisplatin 100 mg/m2 over 24 h on day 1 or alternatively intravenous oxaliplatin 130 mg/m2 on day 1) followed by ASCT. In group A+I, ibrutinib (560 mg orally each day) was added on days 1-19 of R-CHOP cycles and as fixed-duration maintenance (560 mg orally each day for 2 years) after ASCT. In group I, ibrutinib was given the same way as in group A+I, but ASCT was omitted. Three pairwise one-sided log-rank tests for the primary outcome of failure-free survival were statistically monitored. The primary analysis was done by intention-to-treat. Adverse events were evaluated by treatment period among patients who started the respective treatment. This ongoing trial is registered with ClinicalTrials.gov, NCT02858258. FINDINGS: Between July 29, 2016 and Dec 28, 2020, 870 patients (662 men, 208 women) were randomly assigned to group A (n=288), group A+I (n=292), and group I (n=290). After 31 months median follow-up, group A+I was superior to group A with 3-year failure-free survival of 88% (95% CI 84-92) versus 72% (67-79; hazard ratio 0·52 [one-sided 98·3% CI 0-0·86]; one-sided p=0·0008). Superiority of group A over group I was not shown with 3-year failure-free survival 72% (67-79) versus 86% (82-91; hazard ratio 1·77 [one-sided 98·3% CI 0-3·76]; one-sided p=0·9979). The comparison of group A+I versus group I is ongoing. There were no relevant differences in grade 3-5 adverse events during induction or ASCT between patients treated with R-CHOP/R-DHAP or ibrutinib combined with R-CHOP/R-DHAP. During maintenance or follow-up, substantially more grade 3-5 haematological adverse events and infections were reported after ASCT plus ibrutinib (group A+I; haematological: 114 [50%] of 231 patients; infections: 58 [25%] of 231; fatal infections: two [1%] of 231) compared with ibrutinib only (group I; haematological: 74 [28%] of 269; infections: 52 [19%] of 269; fatal infections: two [1%] of 269) or after ASCT (group A; haematological: 51 [21%] of 238; infections: 32 [13%] of 238; fatal infections: three [1%] of 238). INTERPRETATION: Adding ibrutinib to first-line treatment resulted in superior efficacy in younger mantle cell lymphoma patients with increased toxicity when given after ASCT. Adding ibrutinib during induction and as maintenance should be part of first-line treatment of younger mantle cell lymphoma patients. Whether ASCT adds to an ibrutinib-containing regimen is not yet determined. FUNDING: Janssen and Leukemia & Lymphoma Society.

Muscle ultrasound to identify prednisone-induced muscle damage in adults with nephrotic syndrome.

Steroid myopathy is a non-inflammatory toxic myopathy that primarily affects the proximal muscles of the lower limbs. Due to its non-specific symptoms, it is often overshadowed by patients' underlying conditions. Prolonged or high-dosage use of glucocorticoids leads to a gradual decline in muscle mass. There are no tools available to identify the course of steroid myopathy before the patient displays substantial clinical symptoms. In this study, we investigated individuals with nephrotic syndrome receiving prednisone who underwent muscle ultrasound to obtain cross-sectional and longitudinal pictures of three major proximal muscles in the lower limbs: the vastus lateralis, tibialis anterior, and medial gastrocnemius muscles. Our findings revealed that grip strength was impaired in the prednisolone group, creatine kinase levels were reduced within the normal range; echo intensity of the vastus lateralis and medial gastrocnemius muscles was enhanced, the pennation angle was reduced, and the tibialis anterior muscle exhibited increased echo intensity and decreased thickness. The total dose of prednisone and the total duration of treatment impacted the degree of muscle damage. Our findings indicate that muscle ultrasound effectively monitors muscle structure changes in steroid myopathy. Combining clinical symptoms, serum creatine kinase levels, and grip strength improves the accuracy of muscle injury evaluation.

Treatment of primary cardiac diffuse large B-cell lymphoma involving the coronary sinus with R-EPOCH: a case report and literature review.

Primary cardiac lymphomas (PCLs) are a rare clinical entity, in which treatment guidelines remain to be established. Rituximab, etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (R-EPOCH) has been proposed, given that it involves a continuous infusion of anthracycline, reducing the risk of a cardiotoxicity and therefore the theoretical risk of perforation. However, the literature on this method of treatment is scarce. Herein, we present a unique case of a 75-year-old male, diagnosed with primary cardiac diffuse large B-cell lymphoma (DLBCL) with relatively unusual involvement of the coronary sinus, treated first with one cycle of R-EPOCH, followed by three cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) to reduce said risk. To our knowledge, this is one of two cases, in which a patient with PCL was treated this way.

Real-life study on the use of response adapted therapy in patients with Hodgkin Lymphoma: Results from a multicenter experience.

Few data are known regarding the use of interim positron emission tomography (iPET) after the first two cycles (iPET2) of chemotherapy in treatment-naïve classical Hodgkin lymphoma (cHL) in routine clinical practice, and about the real-life adoption of intensification strategies for iPET positive patients. We conducted a multicenter retrospective study on cHL to investigate the use of iPET in the real-life setting, its prognostic role and outcomes of patients early shifted to intensification. Six hundreds and forty-one patients were enrolled (62% had advanced stage). iPET2 was positive in 89 patients (14%) including 8.7% and 17% early and advanced stage patients, respectively (p = 0.003). Among iPET 2 positive cases treatment was immediately modified in 19 cases; in 14 cases treatment was modified after an additional positive iPET4. Overall 56 iPET2 positive patients never received intensified therapies. Most frequently used intensified therapy was autologous stem cell transplantation followed by BEACOPP. After a median follow-up of 72 months, the 5-year progression-free survival (PFS) was 82% with iPET2 positive patients showing a worse PFS compared with iPET2 negative cases: 31% versus 85%. Focusing on advanced stage patients with a positive iPET2, the 5-year PFS was 59% for patients shifted to intensified therapy at any time point versus 61% for patients who never received intensified therapy. Our study confirmed the higher curability of naïve cHL patients in a real-world setting, and the prognostic role of iPET2 in this setting. A poor adherence to response-adapted strategy which however did not translate into a difference in patient outcomes.

Population pharmacokinetics and exposure-response analyses of polatuzumab vedotin in patients with previously untreated DLBCL from the POLARIX study.

Polatuzumab vedotin is a CD79b-directed antibody-drug conjugate that targets B cells and delivers the cytotoxic payload monomethyl auristatin E (MMAE). The phase III POLARIX study (NCT03274492) evaluated polatuzumab vedotin in combination with rituximab, cyclophosphamide, doxorubicin, and prednisone (R-CHP) as first-line treatment of diffuse large B-cell lymphoma (DLBCL). To examine dosing decisions for this regimen, population pharmacokinetic (popPK) analysis, using a previously developed popPK model, and exposure-response (ER) analysis, were performed. The popPK analysis showed no clinically meaningful relationship between cycle 6 (C6) antibody-conjugated (acMMAE)/unconjugated MMAE area under the concentration-time curve (AUC) or maximum concentration, and weight, sex, ethnicity, region, mild or moderate renal impairment, mild hepatic impairment, or other patient and disease characteristics. In the ER analysis, C6 acMMAE AUC was significantly associated with longer progression-free and event-free survival (both p = 0.01). An increase of <50% in acMMAE/unconjugated MMAE exposure did not lead to a clinically meaningful increase in adverse events of special interest. ER data and the benefit-risk profile support the use of polatuzumab vedotin 1.8 mg/kg once every 3 weeks with R-CHP for six cycles in patients with previously untreated DLBCL.

Experience of multi-disciplinary treatment of multiple cerebellar diffuse large B-cell lymphoma: A case report.

RATIONALE: Primary central nervous system lymphoma (PCNSL) is a rare, highly malignant form of non-Hodgkin lymphoma categorized under the diffuse large B-cell type. It accounts for merely 1% of all non-Hodgkin lymphoma cases and comprises approximately 3% of all brain tumors. The involvement of the cerebellum is observed in only 9% of these cases. Recently, we came across an unusual instance: a young man presenting with multiple lesions located specifically within the cerebellum. PATIENT CONCERNS: A 26-year-old male was admitted to the hospital due to severe headaches. He has a medical history of sporadic headaches, accompanied by dizziness, nausea, and vomiting persisting for a month. Over the last 10 days, his headaches have intensified, coupled with decreased vision and protrusion of the eyeballs. Magnetic resonance imaging (MRI) revealed abnormal signals in both cerebellar hemispheres. DIAGNOSES, INTERVENTIONS, AND OUTCOMES: Diagnostic procedures included cerebellar biopsy, posterior fossa decompression, and lateral ventricle drainage. Histopathological examination identified diffuse large B-cell lymphoma (DLBCL) with high proliferative activity. To minimize neurotoxicity, chemotherapy involved intrathecal methotrexate (MTX) injections combined with the CHOP program. The patient has shown good tolerance to the treatment so far. LESSONS: While the definitive optimal treatment approach remains elusive, current chemotherapy centered on high-dose MTX stands as the standard induction therapy. Integrating surgery with radiotherapy and chemotherapy significantly extends patient survival.

Eosinophilic pulmonary disease with ulcerative colitis: A case report.

RATIONALE: Eosinophilic pulmonary disease (EPD) is a general term for a large group of diseases with complex etiology. Ulcerative colitis is an inflammatory bowel disease (IBD). Patients with IBD may have pulmonary involvement. We herein present a case of ulcerative colitis complicated with EPD. PATIENT CONCERNS: A 34-year-old woman with ulcerative colitis presented with dry cough. She had peripheral eosinophilia and apical ground glass opacities on CT (computed tomography) of her chest. Antibiotic treatment was ineffective. DIAGNOSES: Lung biopsy revealed eosinophil infiltration in the alveolar space and interstitial space, so EPD was considered. INTERVENTIONS: After oral administration of prednisone, the lung shadow on CT disappeared when the cough symptoms resolved. However, the symptoms recurred after drug withdrawal, and the lung shadow reappeared on imaging. The cough symptoms and lung shadow disappeared after oral prednisone was given again. Prednisone was slowly discontinued after 6 months of treatment. OUTCOMES: The patient stopped prednisone for half a year. No recurrence or abnormal CT findings were detected during the half-year follow-up. LESSONS: The clinical manifestations of EPD are atypical, laboratory and imaging findings are not specific, and it is difficult to make a definite diagnosis before lung biopsy. The diagnosis depends on pathological examination. Glucocorticoid treatment is effective, but some patients may relapse after drug withdrawal. Active follow-up after glucocorticoid treatment is very important for identifying disease recurrence. Patients with IBD are relatively prone to developing EPD. The etiology of EPD is complex. In clinical practice, we need to make a diagnosis and differential diagnosis to clarify its etiology.
