RESUMEN
Colonic lymphoma is a rare malignant gastrointestinal tumor that can be revealed by an exceptional and serious complication: intestinal obstruction. Treatment is based on surgery and chemotherapy. We here report a case of diffuse colonic large B-cell lymphoma revealed by occlusion and diagnosed based on the examination of surgical specimen in a 64-year-old man who was in complete remission after six courses of R-CHOP.

Importance: Anti-double-stranded DNA (dsDNA) antibody has been reported to have a close relationship with systemic lupus erythematosus (SLE) flares and participates in the pathogenesis of lupus nephritis (LN) as well as causing damage to other organs. However, whether early use of mycophenolate mofetil (MMF) could prevent SLE flares is not clear. Objective: To assess the efficacy and safety of MMF plus prednisone and hydroxychloroquine sulfate compared with prednisone and hydroxychloroquine sulfate alone in patients with SLE. Design, Setting, and Participants: This investigator-initiated, multicenter, observer-blinded randomized clinical trial enrolled 130 participants aged 18 to 65 years and was conducted in 3 hospitals across China. Treatment-naive patients with newly diagnosed SLE, a high titer of anti-dsDNA antibody, and no major organ involvement were included. The study was started September 1, 2018, and the follow-up was completed September 30, 2021. Data were analyzed from December 1, 2021, to March 31, 2022. Interventions: Patients were randomized 1:1 to receive oral prednisone (0.5 mg/kg/d) and hydroxychloroquine sulfate (5 mg/kg/d) (control group) or prednisone (0.5 mg/kg/d) and hydroxychloroquine sulfate (5 mg/kg/d) plus MMF (500 mg twice daily) (MMF group) for 96 weeks. Main Outcomes and Measures: The primary outcome was the proportion of patients presenting with flares according to the Safety of Estrogens in Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) Flare Index. The secondary outcomes included the proportion with lupus low disease activity state at week 96, 36-Item Short Form Health Survey scores before and after treatment, proportion of adverse events (AEs), and changes in SLEDAI-2000 scores and prednisone doses. Results: Among 130 randomized patients (mean [SD] age, 34.5 [12.5] years; 112 [86.2%] women), 119 (91.5%) completed the follow-up. The risk of severe flare was significantly lower in the MMF group (7 of 65 [10.8%]) vs the control group (18 of 65 [27.7%]) (relative risk [RR], 0.39 [95% CI, 0.17-0.87]; P = .01). Additionally, 1 of 65 patients in the MMF group (1.5%) and 9 of 65 in the control group (13.8%) manifested LN (RR, 0.11 [95% CI, 0.01-0.85]; P = .008). Most common serious study drug-related AEs were infections (20 of 65 [30.8%] in the control group and 22 of 65 [33.8%] in the MMF group). Conclusions and Relevance: The findings of this randomized clinical trial suggest that MMF may reduce the rate of severe flare and lower the incidence of LN in patients with new-onset SLE and a high titer of anti-dsDNA antibody without major organ involvement.

Background: Angioimmunoblastic T-cell lymphoma (AITL) is known for its unfavorable survival prognosis. Chidamide has shown efficacy in relapsed/refractory AITL, but its efficacy in newly diagnosed AITL is uncertain. Objective: This retrospective research aimed to evaluate the effectiveness and safety of chidamide when used with doxorubicin, cyclophosphamide, prednisone, and vincristine (CHOP) in comparison to CHOP by itself for individuals newly diagnosed with AITL, and to examine the impact of transplantation. Method: This was an analysis that compared outcomes among patients who received chidamide + CHOP on a clinical trial vs. historical controls who received CHOP alone, enrolling a total of sixty-six treatment-naive AITL patients between April 2014 and November 2022. Among them, thirty-three received chidamide in addition to CHOP (chidamide group), while thirty-three received CHOP alone (control group). The clinical characteristics were balanced between the two groups. All patients were scheduled to undergo up to six courses of treatment before transplantation. Results: The chidamide group had a significantly longer median overall survival (OS) compared to the control group, with a median OS that was not reached, as opposed to 20 months in the control group (p = 0.002). In the control group, the median progression-free survival (PFS) was 11 months, while in the chidamide group, it was 22 months (p = 0.080). In the high-risk group (IPI ≥ 3), the chidamide group demonstrated notably superior complete response (CR) and overall response rate (ORR) compared to the control cohort (p = 0.002, p = 0.034). The PFS and OS in the chidamide group were not reached, and there were significant differences compared to the control group (p = 0.007, p = 0.003). The median OS of the transplanted group was longer than the non-transplanted group (p = 0.004). On multivariate analysis, chidamide group reduced the hazards of death in the total cohort. Conclusion: As the study was non-random and retrospective, Chidamide combined with chemotherapy should be tested in randomized trials given its potential to improve prognosis in treatment-naive AITL patients. Furthermore, autologous hematopoietic stem cell transplantation (auto-HSCT) has demonstrated enhanced overall survival in individuals with AITL.

First-line treatment for advanced-stage diffuse large B-cell lymphoma (DLBCL) typically involves 6x R-CHOP21 or 6x R-CHOP21 with two additional rituximab administrations (6x R-CHOP21 + 2 R). In contemporary practice, this treatment choice might be guided by interim PET scan results. This nationwide, population-based study investigates the comparative effectiveness of these treatment regimens in an era where interim PET-guided treatment decisions were not standard practice. Utilizing the Netherlands Cancer Registry, we identified 1577 adult patients diagnosed with advanced-stage DLBCL between 2014-2018 who completed either 6x R-CHOP21 (43%) or 6x R-CHOP21 + 2 R (57%). We used propensity scores to assess differences in event-free survival (EFS) and overall survival (OS). At five years, EFS (hazard ratio of 6x R-CHOP21 + 2 R versus 6x R-CHOP21 [HR] = 0.89; 95% confidence interval [CI], 0.72-1.09) and OS (HR = 0.93; 95% CI, 0.73-1.18) were not significantly different between both regimens. In exploratory risk-stratified analysis according to the International Prognostic Index (IPI), high-IPI patients (i.e., scores of 4-5) benefit most from 6x R-CHOP21 + 2 R (5-year absolute risk difference of EFS = 16.8%; 95% CI, -0.4%-34.1% and OS = 12.1%; 95% CI, -5.4-29.6%). Collectively, this analysis reveals no significant differences on average in EFS and OS between the two treatments. However, the potential benefits for high-risk patients treated with 6x R-CHOP21 + 2 R underscore the need for future research.

INTRODUCTION: The diffuse large B-cell lymphoma (Dlbcl) is the most common non-Hodgkin lymphoma and at highest incidence among the elderly. Despite the improved outcomes of patients treated with the first-line (1L) standard of care until the end of 2022, composed by rituximab and polychemotherapy (R-Chop), during the last 20 years, the rate of relapsed and refractory Dlbcl (rrDlbcl) remains elevated. This study has identified and analyzed patients newly diagnosed with Dlbcl and treated with 1L, from the perspective of the Italian National Health Service (Ssn). METHODS: From the administrative database of Fondazione Ricerca e Salute (ReS) including ~5.5 million inhabitants/year in Italy, adults with a new in-hospital Dlbcl diagnosis (index date) and treated with 1L in 2018, 2019, 2020 and 2021 were identified and characterized in terms of demographics and comorbidities during a period (from 4 to 8 years) preceding index date. From 1 to 4 years following index date (follow-up), overall survival (Kaplan-Meier curves), percentage distribution of patients by line of therapy including dispensation/administration of chemo-immunotherapy, hemopoietic stem cell transplantation (Hsct), and direct healthcare costs charge to the Ssn, were evaluated. RESULTS: Overall, from the ReS database, 206 patients newly diagnosed with Dlbcl and treated with 1L from 2018 to 2021 in Italy (incidence from 0.9 to 1.7 x100,000 adult inhabitants) were identified. They were mainly older (median age 68 [56; 75] years), males (56%) and affected by ≥2 comorbidities (52%), mostly cardiometabolic. During 4 years of follow-up, 56% of cases in 2018 survived. During the first follow-up year: 73%, 80%, 100% and 35% of cases in 2018, 2019, 2020 and 2021, respectively, received a 2L; 42% and 64% of cases in 2018 and 2020, respectively, received a 3L. At least one Hsct was found as a 2L among cases in 2018, 2020 and 2021. On average, each patient newly diagnosed with Dlbcl and treated with 1L from 2018 to 2021 caused a total expenditure directly charged to the Ssn ranging from 20,000 to 30,000 during the first follow-up year (chemo-immunotherapy accounted for 40-53%), which reduced with time in favor of other drugs and Hsct. CONCLUSIONS: This analysis confirms the high rate of rrDlbcl and the high economic impact charged to the SSN to support first the chemo-immunotherapy, then the chronic care and the absence of standardized further lines of therapy for patients with rrDlbcl.

Richter transformation (RT) is an aggressive lymphoma occurring in patients with chronic lymphocytic leukaemia. Here we investigated the anti-CD3/anti-CD19 T-cell-engager blinatumomab after R-CHOP (i.e. rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) in patients with untreated RT of diffuse large B-cell lymphoma histology (NCT03931642). In this multicentre phase 2 study, patients without complete response (CR) after two cycles of R-CHOP were eligible to receive an 8-week blinatumomab induction via continuous vein infusion with stepwise dosing until 112 µg/day. The primary endpoint was the CR rate after blinatumomab induction and secondary endpoint included safety, response duration, progression-free and overall survival. Thirty-nine patients started the first cycle of R-CHOP, 25 of whom received blinatumomab. After blinatumomab induction, five (20%) patients achieved CR, four (16%) achieved partial response, and six (24%) were stable. Considering the entire strategy, the overall response rate in the full-analysis-set was 46% (n = 18), with CR in 14 (36%) patients. The most common treatment-emergent adverse events of all grades in the blinatumomab-safety-set included fever (36%), anaemia (24%), and lymphopaenia (24%). Cytokine release syndrome (grade 1/2) was observed in 16% and neurotoxicity in 20% of patients. Blinatumomab demonstrated encouraging anti-tumour activity (the trial met its primary endpoint) and acceptable toxicity in patients with RT.

The mechanism underlying intestinal fibrosis, the main complication of inflammatory bowel disease (IBD), is not yet fully understood, and there is no therapy to prevent or reverse fibrosis. We evaluated, in in vitro cellular models, the ability of different classes of drugs currently used in IBD to counteract two pivotal processes of intestinal fibrosis, the differentiation of intestinal fibroblasts to activated myofibroblasts using CCD-18Co cells, and the epithelial-to-mesenchymal transition (EMT) of intestinal epithelial cells using Caco-2 cells (IEC), both being processes induced by transforming growth factor-ß1 (TGF-ß1). The drugs tested included mesalamine, azathioprine, methotrexate, prednisone, methylprednisolone, budesonide, infliximab, and adalimumab. The expression of fibrosis and EMT markers (collagen-I, α-SMA, pSmad2/3, occludin) was assessed by Western blot analysis and by immunofluorescence. Of the drugs used, only prednisone, methylprednisolone, budesonide, and adalimumab were able to antagonize the pro-fibrotic effects induced by TGF-ß1 on CCD-18Co cells, reducing the fibrosis marker expression. Methylprednisolone, budesonide, and adalimumab were also able to significantly counteract the TGF-ß1-induced EMT process on Caco-2 IEC by increasing occludin and decreasing α-SMA expression. This is the first study that evaluates, using in vitro cellular models, the direct antifibrotic effects of drugs currently used in IBD, highlighting which drugs have potential antifibrotic effects.

OBJECTIVE: To investigate the clinical features and prognostic factors of patients with primary extranodal diffuse large B-cell lymphoma (DLBCL) in the rituximab era. METHODS: The continuous data of newly diagnosed DLBCL patients with complete case data and first-line treated with rituximab, cyclophosphamide, epirubicin, vincristine, prednisone (R-CHOP) or R-CHOP treatment admitted to the Affiliated Hospital of Inner Mongolia Medical University from January 2013 to November 2023 were retrospectively analyzed. The clinical and molecular immunological features and prognosis of extranodal DLBCL were analyzed, Logistics regression model was used to analyzed the influencing factors of patients prognosis. RESULTS: A total of 237 patients were enrolled, of which 54.4% (129 cases) were primary extranodal sources of DLBCL, and the most common extranodal sites were as follows: stomach (19.4%), colon (14.7%), tonsils (12.4%), skin/muscle (9.3%), central (7.7%), nasal/nasopharynx (6.2%), bone marrow (5.4%), testes (4.7%). The 3-year PFS and OS of DLBCL patients with extranodal involvement of bone marrow, central, liver, gastrointestinal or pulmonary origin were significantly lower than those of other patients with extranodal DLBCL of non-special site origin, and the difference was statistically significant (PFS: 65.2% vs 76.7%, P =0.008; OS: 82.6% vs 88.3%, P =0.04). Multivariate analysis showed that the prognostic factors affecting OS included NCCN-IPI score >3 (OR : 0.142, 95%CI : 0.041-0.495, P =0.002), non-germinal center source (OR : 2.675ï¼95%CI :1.069-6.694ï¼P =0.036), and DEL patients (OR : 0.327, 95%CI : 0.129-0.830, P =0.019). An NCCN-IPI score >3 was the only independent adverse prognostic factor for PFS (OR : 0.235, 95%CI : 0.116-0.474, P < 0.001). CONCLUSION: Patients with primary extranodal source DLBCL are more common in gastrointestinal involvement, and the overall prognosis is worse than that of patients with lymph node origin. NCCN-IPI score is an important independent adverse prognostic factor for predicting overall survival and progression-free survival in patients with primary extranodal diffuse large B-cell lymphoma.

This study aims to test the hypothesis that disease duration may affect the response to generic tofacitinib (TOF) and investigate the influence of concomitant medications with TOF on elderly rheumatoid arthritis (RA). This study retrospectively collected 76 elderly patients (age > 60) treated with TOF from 2019 to 2023 and grouped them according to age of disease onset. Data were collected from baseline to the last follow-up visit within 24 months. The demographic characteristics and follow-up results were compared. TOF retention and the effect of concomitant drugs (methotrexate, MTX, prednisone) were analyzed using Kaplan-Meier plots and COX regression analysis. Canonical correlation analysis (CCA) was used to explore the correlation among demographic characteristics, medication regimen, and improved clinical outcomes. There was no significant difference in the proportion of patients achieving low disease activity (LDA) between different disease duration groups. Patients in the group of MTX had a shorter time of using TOF in follow-up (log-rank p = 0.041). Prednisone dosage at baseline had a predictive value for functionally disabled situation. We found significant associations between discontinuation of TOF in the last follow-up and getting LDA. A total result of CCA yielded a significant positive correlation with set 1 (demographic characteristics and medication regimen) and set 2 (improved clinical outcomes) (canonical coefficient = 0.887, p < 0.001). Disease duration may not affect response to generic TOF and medication regimen was the factor related to efficacy of generic TOF in elderly RA in the real world. Demographic characteristics and medication regimen were correlated positively with improved clinical outcomes. Key Points ⢠There is scarce data from the western area of China regarding the use of tofacitinib in elderly rheumatoid arthritis patients, despite widespread use. ⢠In this retrospective analysis of 76 elderly patients at a single center, we found disease duration may not affect response to generic TOF. ⢠Concomitant MTX might contribute to better control of the disease activity. ⢠Concomitant prednisone dosage at baseline was the independent risk factor for functionally disabled situation.

BACKGROUND Fermenting bacilli producing lactic acid, including Bifidobacterium spp., are supposed to have low pathogenicity and no virulence for humans. Probiotics consisting of those fermenting bacilli can prevent and treat symptomatic gastrointestinal conditions, such as diarrhea. We use probiotics even in cancer patients, those who are immunocompromised, because a preferable effect to the intestinal commensal microbiome has been shown in a recent report. Some case reports warn of a rare risk of bloodstream infection caused by probiotics. However, complete prohibition of probiotic use in cancer patients abandons the benefits. CASE REPORT A 75-year-old Japanese woman with malignant lymphoma was treated with immune-chemotherapy regimen consisting of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP). The patient had onset of febrile neutropenia during chemotherapy and had Bifidobacterium breve bloodstream infection on day 8 after the eighth R-CHOP treatment. She had usually eaten commercial yogurt every morning. This yogurt was produced from only Lactobacillus bulgaricus and Streptococcus thermophilus. It did not contain Bifidobacterium breve. The bloodstream infection in this case looked like it derived from her food; however, it was not associated with her habitual foods. The patient was treated with meropenem for 8 days and experienced complete remission of the bloodstream infection. CONCLUSIONS We speculate that fermenting bacilli can also be a source of bloodstream infection, not necessarily associated with probiotic strains, in cancer patients treated with chemotherapy. Additionally, we recommend that probiotics can alleviate alimentary tract symptoms in immunocompromised patients.

Due to the lack of treatment guidelines for the management of advanced-stage marginal zone lymphoma (MZL), only one chemoimmunotherapy-cyclophosphamide, vincristine, and prednisone plus rituximab (R-CVP)-is reimbursed in the first-line setting in South Korea. The aim of this study was to develop a consensus-based recommendation for the treatment of patients with advanced-stage MZL. Twelve hematologist oncologists participated in a two-round Delphi process to identify consensus on the management of patients with advanced-stage MZL in South Korea. Physicians rated their level of agreement with each statement on a four-point Likert scale. Statements were divided into two sections: definitions used in clinical practice and clinical management of patients with advanced-stage MZL. Consensus was reached for 23 of 33 (69.7%) and 5 of 13 statements (38.5%) in rounds 1 and 2, respectively. There was strong consensus (91.7%) that advanced-stage MZL subtypes are defined according to the Lugano staging system. First-line systemic treatment should be prescribed for patients with symptomatic advanced-stage MZL. Although there was unanimous agreement that R-CVP is the standard first-line treatment for advanced-stage MZL, physicians also agreed that bendamustine with rituximab (BR) has greater efficacy than R-CVP as first-line treatment (91.7%). For the treatment of relapsed/refractory advanced-stage MZL, BR and R-CVP can be repeated in patients with short (< 24 months) and long remission periods (≥ 24 months), respectively. This study provides insights on the management of patients with advanced-stage MZL in South Korea. This may enhance clinical decision-making, thus improving patient outcomes.

Myelodysplastic syndrome (MDS) represents a spectrum of myeloid disorders occasionally linked to autoimmune diseases. Here, we present a case of a 60-year-old man demonstrating an unusual coexistence of MDS with warm-autoantibody autoimmune hemolytic anemia (wAIHA). Diagnostic evaluation, including positive direct antiglobulin testing, confirmed the autoimmune etiology of his anemia despite his low-risk MDS classification. Prompt initiation of prednisone therapy resulted in significant hematological and clinical improvement, allowing for a conservative management approach without transfusion requirements. This case underscores the importance of identifying the relationship between wAIHA and MDS, particularly in low-risk scenarios. Moreover, these findings suggest the efficacy of corticosteroids in managing autoimmune anemia in the context of concomitant wAIHA and MDS.

BACKGROUND: Managing metastatic castration-resistant prostate cancer (mCRPC) in men aged ≥ 75 is challenging due to limited data. Regardless of age, in real-world clinical practice, most mCRPC still derive from failure of androgen deprivation therapy (ADT) with or without docetaxel (D) for metastatic castration-sensitive prostate cancer (mCSPC). As abiraterone acetate plus prednisone (AA) and enzalutamide (Enza) are common first-line treatments for mCRPC. The impact of prior use of D for mCSPC on the efficacy and safety of AA or Enza in this older population remains unclear. METHODS: A cohort of patients aged ≥ 75 years starting AA or Enza as first-line therapy for mCRPC from January 2015 to April 2019 was identified from the registries of 10 institutions. Patients were categorized into 2 groups based on previous use of D for mCSPC. Primary endpoints were cancer-specific survival (CSS) from AA or Enza start, CSS from ADT onset, and safety. We used Kaplan-Meier method to estimate the endpoints distribution, including median values with 95% confidence intervals (95% CI). RESULTS: Of the 337 patients identified, 24 (7.1%) received ADT+D and 313 (92.9%) received ADT alone for mCSPC. Median follow-up from AA/Enza start was 18.8 months. Median CSS from ADT or AA/Enza was not significantly different between ADT+D and ADT alone cohorts (71.9 vs. 52.7 months, P = .97; 25.4 vs. 27.2 months, P = .89, respectively). No statistically significant difference in adverse events (AEs) of any grade rate (58.3% vs. 52.1%, respectively; P = .67) or grade ≥ 3 (12.5% vs. 15.7%, respectively; P = 1.0) was found between ADT+D and ADT alone cohorts. CONCLUSIONS: Despite the innate limitations of a retrospective design and relatively small size of the ADT+D cohort, this analysis suggests that elderly men receiving AA or Enza as first-line therapy for mCRPC have similar survival outcomes and tolerability, regardless of previous D for mCSPC.

INTRODUCTION: The current treatment regimens for Hodgkin's lymphoma (HL) are associated with high incidences of adverse events. PURPOSE: This study aimed to compare the efficacy and safety of doxorubicin + bleomycin + vincristine + dacarbazine (ABVD) and standard bleomycin + etoposide + doxorubicin + cyclophosphamide + vincristine + procarbazine + prednisone (BEACOPP) chemotherapy in the treatment of advanced stage HL. METHODS: This multicenter, randomized, parallel, open, positive control noninferiority trial was conducted from 2016 to 2019 and comprised 93 subjects who were randomized in a 1:1 ratio between the treatment (BEACOPP; n = 44) and control (ABVD; n = 49) groups. RESULTS: The primary efficacy endpoint of this trial was the objective response rate (ORR) after eight cycles of chemotherapy, which was 100.00% (36/36) in the treatment group and 95.74% (45/49) in the control group. The incidence of adverse reactions was 100% in both groups. Significant differences (P < 0.05) in the incidences of grade 3 (39/44 [88.64%] vs. 23/49 [46.94%]) and grade 4 (27/44 [61.36%] vs. 8/49 [16.94%]) adverse events were observed between the treatment and control groups, respectively. However, most of these reactions were manageable, with no serious consequences, and were reversible after discontinuation of the treatment. CONCLUSION: Both regimens had a similar ORR and were associated with a high number of adverse events. The ABVD regimen was better tolerated and safer than the standard BEACOPP regimen. This study indicates that the standard BEACOPP regimen may be considered as a treatment option for patients with advanced HL.

Non-Hodgkin's lymphoma (NHL) is the most common type of Gastrointestinal (GI) lymphoma with known complications such as bleeding, obstruction and perforation. In this article we present a 59-year-old male patient diagnosed with Peripheral T cell Lymphoma - Not Otherwise Specified (PTCL-NOS) with GI involvement was started on chemotherapy. On day 2 post completion of first cycle of chemotherapy, patient had presented to the emergency department with sudden onset abdominal pain and distension. On evaluation, he was diagnosed with multiple perforations in the small bowel. Patient underwent exploration with primary repair of few perforations and ileal resection with double barrel ileostomy. Chemotherapy plays an important role in the management of NHL. One well-known NHL consequence, intestinal perforation, can happen at the time of initial presentation or after starting chemotherapy. Surgeons should be aware of possibility of such complications and high-risk factors for perforation. At present, there is no role for elective surgery in GI lymphoma and is mainly reserved for complications like uncontrolled bleeding, obstruction or perforation.

BACKGROUND: MAGNITUDE (NCT03748641) demonstrated favourable outcomes with niraparib plus abiraterone acetate plus prednisone (+AAP) versus placebo+AAP in patients with BRCA1/2-altered metastatic castration-resistant prostate cancer (mCRPC). Imbalances in prognostic variables were reported between arms, which impacts estimation of both the clinical benefit and costeffectiveness of niraparib+AAP for healthcare systems. A pre-specified multivariable analysis (MVA) demonstrated improved overall survival (OS) with niraparib+AAP. Here, we used an inverse probability of treatment weighting (IPTW) model to adjust for covariate imbalances and assess time-to-event outcomes. METHODS: IPTW analysis of time-to-event outcomes was conducted using data from patients with BRCA1/2-altered mCRPC (N = 225) in MAGNITUDE. Patients received niraparib+AAP or placebo+AAP. OS, radiographic progression-free survival, time to symptomatic progression, time to initiation of cytotoxic chemotherapy and time to prostate-specific antigen progression were assessed. Weighted Kaplan-Meier curves were generated for each endpoint, and adjusted hazard ratios (HR) were obtained from a weighted Cox model. RESULTS: Improvements in survival outcomes were estimated for niraparib+AAP versus placebo+AAP: unadjusted median OS was 30.4 months versus 28.6 months, respectively (HR: 0.79; 95 % confidence interval [CI]: 0.55, 1.12; p = 0.183). Following IPTW, median OS increased to 34.1 months with niraparib+AAP versus a decrease to 27.4 with placebo (HR: 0.65; 95 % CI: 0.46, 0.93; p = 0.017). Similar improvements were observed for other time-to-event endpoints. CONCLUSIONS: IPTW adjustment provided a more precise estimate of the clinical benefit of niraparib+AAP versus placebo+AAP in patients with BRCA1/2-altered mCRPC. Results were consistent with the pre-specified MVA, and further demonstrated the value of adjusting for baseline imbalances, particularly in smaller studies. TRIAL REGISTRATION: NCT03748641 (MAGNITUDE).

OBJECTIVE: This paper presents an analysis of the pregnancy trajectory and therapeutic regimen documentation of a primigravida with APSN. It aims at communicating the therapeutic approach and preventive measures for APSN in pregnancy. CASE PRESENTATION: This paper reports the trajectory and therapeutic regimen documentation of a primigravida with APSN. The APSN was discovered in a primigravida woman aged 26 years at 11 weeks of gestation. The initial therapy regimen consists of daily administration of prednisone 10 mg, hydroxychloroquine 200 mg, dapparin 5000 IU, and aspirin 50 mg. At a gestational age of 20 + 3 weeks, the dosage of dapparin was modified to 5000 IU/other day, along with a significant rise in urinary protein level seen at 30 + 3 weeks of gestational age. The initial dosage of dapanin sodium was renewed. The patient delivered at 38 + 3 weeks of gestation without other complications. CONCLUSION: It is imperative to acknowledge that altering the dosage and administration of medication should not be done haphazardly during pregnancy.

Diffuse large B-cell lymphoma (DLBCL), with approximately 150,000 new cases worldwide each year, represent nearly 30% of all cases of non-Hodgkin lymphoma (NHL) and are phenotypically and genetically heterogeneous. A gene-expression profile (GEP) has identified at least three major subtypes of DLBCL, each of which has distinct clinical, biological, and genetic features: activated B-cell (ABC)-like DLBCL, germinal-center B-cell (GCB)-like DLBCL, and unclassified. Different origins are associated with different responses to chemotherapy and targeted agents. Despite DLBCL being a highly heterogeneous disease, more than 60% of patients with DLBCL can be cured after using rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) to inhibit the growth of cancer cells while targeting the CD20 receptor. In recent decades, the improvement of diagnostic levels has led to a refinement classification of DLBCL and the development of new therapeutic approaches. The objective of this review was to summarize the latest studies examining genetic lesions and therapies for DLBCL.
