A Rare Case of Signet Ring Cell Lymphoma and Review of the Literature

Signet ring cell lymphoma (SRCL) is a non-Hodgkin's lymphoma with a very rare variant. Although this morphology is frequently seen in follicular lymphoma, it can also be observed in the group of diffuse large B-cell lymphomas. A seventy-six year old woman with known diagnosis of gastric adenocarcinoma, tubular type, moderately differentiate presented with a lymphadenopathy with high FDG uptake (SUVmax: 21.3) in PET/CT during follow-up. A tru-cut biopsy was performed for histopathological diagnosis. Diffuse infiltrative singet ring neoplastic cells showed negativity for PanCK, CK7, CK20, S100, SMA, calretinin and vimentin. The panel was then expanded to include SRCL, a rare variant of lymphoma. Additional immunohistochemical evaluation revealed positivity for CD20, CD19, PAX-5 and Bcl-2. Ki-67 proliferation index was about 80%. CD3, CD30, Myc, Bcl-6, ALK, Cyclin-D1, CD23, CD10, CD21, and MUM-1 were negative. EBER was also negative by chromogen in situ hybridization (CISH). Based on these data, diffuse large B-cell lymphoma (DLBCL) was considered. We herein reported a case of signet ring cell lymphoma discussed its clinical and morphological features with regard to the literature.

Non-Invasive Imaging Including Line-Field Confocal Optical Coherence Tomography (LC-OCT) for Diagnosis of Cutaneous Lymphomas

Background/Objectives: Primary cutaneous lymphomas (PCL) are a heterogeneous group of non-Hodgkin lymphomas arising from malignant T (CTCL) or B (CBCL) cells, often mimicking other skin conditions. Recently, non-invasive diagnostic imaging modalities, including dermoscopy, Reflectance Confocal Microscopy (RCM), and Line-field Optical Coherence Tomography (LC-OCT), have become increasingly important, supporting clinicians in clinical practice. Hence, our study aimed to describe dermoscopic, RCM, and LC-OCT features of PCL and to explore their role in PCL management. Methods: Between December 2022 and January 2024, 40 lesions of 25 patients with PCL were retrospectively analyzed at the Dermatologic Unit of the University of Siena, Italy. Predefined dermoscopic, LC-OCT, and RCM criteria were assessed and their frequencies were calculated. Results: At dermoscopy, CTCL lesions were characterized by pinkish structureless areas (58,6%) and homogeneous distributed dotted vessels (35,7%), whereas 57.1% of CBCL presented with orange-yellow structureless areas. Considering CTCL, lymphocytes in the epidermis, dermal-epidermal junction, and dermis were detected by LC-OCT in 73.1%, 66.7%, and 51.9% and by RCM in 72.2%, 55.6%, and 61.1% of cases, respectively. The detection of lymphocytes was more precise using RCM than LC-OCT in CTCL (p < 0.001). Dermal infiltration of medium-reflective cells was visible in 80% and 40% of CBCL cases by LC-OCT and RCM, respectively. Conclusions: Non-invasive imaging techniques may support clinicians in managing PCL; however, further studies are mandatory in this field.

Combined immunohistochemical profile CD10/LMO2/MYC is a useful tool to screen MYC rearrangements in aggressive large B-cell lymphomas.

Aggressive large B-cell lymphomas (LBCL) are a heterogeneous group of lymphomas with variable biological characteristics, for which the identification of MYC rearrangements (MYCr) is a defining and prognostic feature. Both the International Consensus Classification and the 5th edition of the World Health Organization Classification of Hematolymphoid Tumors recommend performing cytogenetic studies in all aggressive LBCL to detect MYCr. Since MYCr incidence is low, cost-effective screening tools are necessary. We asked whether the immunohistochemical combined profile of CD10, LMO2, and MYC could be a useful tool to screen for MYCr. For this purpose, we used two strategies: first, a scoring system assigning 0 points each for CD10 - , LMO2 + , and MYC - and 1 point for CD10 + , LMO2 - , and MYC + , adding the results, and second, an algorithm that selected tumors with CD10 + /LMO2 - profile and/or MYC overexpression. All analyses were performed in a training series including 482 cases from a single center and a validation series of 124 patients from two centers. The resulting system classified cases in scores from 0 to 3. Scores 0 and 1 had low MYCr (0/92 and 7/224, 3%, respectively), being higher for scores 2 (40/98, 41%) and 3 (61/68, 90%) (P < 0.001) in the training cohort. The incidence of MYCr in the validation series was as follows: score 0, 0/29 cases; score 1, 3/64 (5%); score 2, 10/23 (43.5%); score 3, 8/8 (P < 0.001). Sensitivity and negative predictive values were respectively 93.5% and 97.8% for the training and 85.7% and 96.8% for the validation cohorts. The algorithm rescued 2 and 1 MYCr cases included in score 1 from both series. In conclusion, we suggest that both approaches combining the interpretation of CD10/LMO2/MYC by immunohistochemistry are useful to screen for MYCr.

Diagnostic value of baseline 18F-FDG PET/CT and peripheral blood inflammatory markers for aggressive lymphoma in non-Hodgkin's lymphoma.

This study aims to investigate the diagnostic value of baseline F18 fluorodeoxyglucose (FDG) PET/computed tomography (CT) parameters and peripheral blood inflammatory markers in aggressive lymphoma of non-Hodgkin lymphoma (NHL) and the correlation between peripheral blood inflammatory markers and maximum standardized uptake value (SUVmax). We conducted a retrospective analysis including 121 patients with NHL. Patients were divided into aggressive lymphoma group and indolent lymphoma group. Mann-Whitney U test, chi-square test and multivariate stepwise logistic regression were used to analyse. Subsequently, receiver operating characteristic (ROC) curve analysis was conducted to evaluate the diagnostic performance. Additionally, Spearman correlation analysis was utilized to explore the correlation between peripheral blood inflammatory markers and SUVmax. Leptin mass criterion uptake value (SUL)max, SUVmax, SUVavg, SUVpeak, focal SUVmax/liver SUVmax, focal SUVmax/ mediastinal SUVmax, SULavg, SULpeak, systemic immune-inflammation, neutrophil ratio, total lesion glycolysis, neutrophils versus lymphocyte ratio, platelet-to-lymphocyte ratio, hemoglobin-to-white blood cell ratio, lactate dehydrogenase and lymphocyte ratio between two groups were statistically significant (P < 0.05). SUVmax was an independent influencing factor, and the area under the ROC curve was 0.862. There was a positive correlation between the platelet-to-lymphocyte ratio and SUVmax (r = 0.239; P = 0.008). PET/CT parameters and peripheral blood inflammatory markers have certain value in the diagnosis of aggressive lymphoma in NHL, among which SUVmax is an independent influencing marker and is positively correlated with PLR.

B-227 Customized molecular tests for minimal residual disease: a tool for therapeutic decisions in follicular lymphoma patients

Abstract Background Monitoring of minimal residual disease (MRD) is based on accurate laboratory tests which can recognize a small fraction of malignant cells that survived the course of treatment. Several studies of the B-non-Hodgkin lymphoma group have been presented that MRD positivity at the end of treatment is a negative prognostic index. Follicular lymphoma (FL) is a chronic indolent malignancy, which response highly to immuno-chemotherapy followed by prolonged remissions but with inevitable relapse in most patients. The GALLIUM study showed that immuno-chemotherapy combinations, 6 cycles of bendamustine-obinutuzumab (BO), is the most efficacious treatment, but with severe side effects .In addition, 90% of patients achieved negative MRD from peripheral blood (PB) or bone marrow (BM) after only 3 BO cycles. These findings raise the possibility for MRD based treatment approach, where the duration of chemotherapy could be decided according to MRD status at mid-induction (MI). Identification of a marker in the PB and/or BM of each FL patient which will be use to the design of a sensitive RQ-PCR test for MRD detection for follow-up. Methods Qualitative PCR for translocation 14:18 and for the VDJ rearrangement sequence of the immunoglobulin heavy chain was used for marker identification. MRD monitoring was done by RQ-PCR. MRD monitoring for VDJ was designed specifically to each patients based on his VDJ sequence. MRD was assessed on PB and BM at MI. Results Marker for monitoring was identified at 11/21 patients in this study. After 3 combined therapy cycles, 7 patients were found to have MRD negativity by RQ-PCR therefore continue with immuno-therapy only. MRD positivity was assessed in BM of 3 patients (0.11%, 0.022%, and 0.133%). These 3 patients continued with the combined therapy. RQ-PCR sensitivity was 10-4-10-5. Conclusions This study will reveal the ability to use sensitive and specific MRD that has to be designed for each patient according to his marker and enable the establishment of a treatment with a high safety profile for FL patients. Correlation between MRD status and clinical and safety parameters will be assessed at the end of the study, 30 months after the first treatment, taking into account MRD status from different time point of the follow-up period.

The Landscape of Cutaneous T-Cell Lymphoma (CTCL) in the Middle East and North Africa (MENA) and the Establishment of the MENA CTCL Working Group

The high cancer burden in the Middle East and North Africa (MENA region) is coupled with an increasing cancer incidence. While the MENA region constitutes 6% of the world’s population, it remains underrepresented in clinical trials. Cutaneous T-cell lymphomas (CTCLs) represent a heterogeneous group of rare extranodal non-Hodgkin lymphomas with variable clinical presentation. In the MENA region, where darker skin colors are more common than in the West, CTCL generally presents at a younger age and with distinct clinical features that necessitate special expertise and management across disciplines: rare forms of CTCL are more common (hypo- and hyperpigmented MF) and a higher prevalence of pediatric MF is noticed. The multidisciplinary approach to cancer management is growing worldwide and is necessary for the comprehensive management of CTCL. The MENA CTCL group was established with the aim of creating a collaborative environment for the diagnosis and treatment of CTCL in the region. Its first meeting was held in May 2023. The group plans to increase the global representation of the MENA region and establish CTCL registries and patient advocacy groups in the region.

The Tumor Microenvironment as a Therapeutic Target in Cutaneous T Cell Lymphoma.

Cutaneous T cell lymphomas (CTCLs) are a heterogeneous group of non-Hodgkin lymphomas, with mycosis fungoides and Sézary syndrome being the two common subtypes. Despite the substantial improvement in early-stage diagnosis and treatments, some patients still progress to the advanced stage with an elusive underpinning mechanism. While this unsubstantiated disease mechanism coupled with diverse clinical outcomes poses challenges in disease management, emerging evidence has implicated the tumor microenvironment in the disease process, thus revealing a promising therapeutic potential of targeting the tumor microenvironment. Notably, malignant T cells can shape their microenvironment to dampen antitumor immunity, leading to Th2-dominated responses that promote tumor progression. This is largely orchestrated by alterations in cytokines expression patterns, genetic dysregulations, inhibitory effects of immune checkpoint molecules, and immunosuppressive cells. Herein, the recent insights into the determining factors in the CTCL tumor microenvironment that support their progression have been highlighted. Also, recent advances in strategies to target the CTCL tumor micromovement with the rationale of improving treatment efficacy have been discussed.

Magnetic resonance diffusion-weighted imaging in lacrimal gland lymphoma versus inflammation: A comparative study.

To determine the role of diffusion-weighted imaging (DWI) with apparent diffusion coefficient (ADC) in differentiating the inflammatory process and malignant lymphoma of the lacrimal gland. A retrospective analysis of all subjects who underwent lacrimal gland biopsy and magnetic resonance (MR) imaging with DWI sequences during a 10-year period at the Sheba Medical Center, Israel. The lacrimal glands' ADC values were documented bilaterally by blinded observers and correlated with the final histology verified diagnoses. Twenty-eight patients were included, with 19 females (68%) with a mean ± SD age of 48.1 ± 25.7 years. The right orbit was involved in 14 cases (50%) and the left in 13 (46%); one patient (4%) had bilateral involvement. Seventeen cases (61%) had a final diagnosis of idiopathic inflammation or dacryoadenitis, and six cases (21%) were diagnosed with lymphoma. Additional diagnoses included pleomorphic adenoma in 3 (11%), adenoid cystic carcinoma, and solitary fibrous tumor. Lower mean ADC values were observed in the lymphoma versus inflammatory group (1.03 × 10-3 Vs. 1.45 × 10-3, P = 0.02). Restricted diffusion on MR imaging can serve as a diagnostic tool in the differentiation between inflammatory processes of the lacrimal gland and lymphoma.

Loss of CCL28 and CXCL17 Expression and Increase in CCR1 Expression May Be Related to Malignant Transformation of LGBLEL into Lymphoma.

To investigate the differential expression of the chemokine signaling pathway in lacrimal gland benign lymphoepithelial lesion (LGBLEL) and lacrimal lymphoma, providing insights into the mechanisms underlying malignant transformation and aiding clinical differentiation. Transcriptome analysis was conducted on patients with LGBLEL, lymphoma, and orbital cavernous hemangioma (CH). Three cases of LGBLEL and three cases of lymphoma were randomly selected as control and experimental groups, respectively. A real-time quantitative polymerase chain reaction (RT-qPCR) was used to validate genes associated with the chemokine signaling pathway. Immunohistochemical (IHC) staining and quantitative Western blotting (WB) were performed for precise protein quantification. Transcriptome analysis revealed differential expression of the chemokine signaling pathway between the LGBLEL and lymphoma groups, identifying ten differentially expressed genes: CCL17, VAV2, CXCR5, NRAS, HCK, RASGRP2, PREX1, GNB5, ADRBK2, and CCL22. RT-qPCR showed that, compared to the lymphoma group, the LGBLEL group had significantly higher expression of CCL28, CXCL17, HCK, GNB5, NRAS, and VAV2 (p = 0.001, <0.001, <0.001, <0.001, =0.020, <0.001, respectively) and lower expression of CCR1 (p = 0.002). IHC staining and quantitative analysis confirmed significant differences in protein expression between the groups for CCL28, CCR1, CXCL17, HCK, GNB5, NRAS, and VAV2 (p = 0.003, 0.011, 0.001, 0.024, 0.005, 0.019, and 0.031, respectively). While IHC provided localization, WB offered greater precision. WB revealed that, compared to the lymphoma group, the LGBLEL group exhibited significantly higher expression of CCL28, CXCL17, HCK, GNB5, NRAS, and VAV2 (p = 0.012, 0.005, 0.009, 0.011, 0.008, and 0.003, respectively) and lower expression of CCR1 (p = 0.014). The chemokine signaling pathway plays a role in the malignant transformation of LGBLEL. The decreased expression of CCL28 and CXCL17, coupled with the increased expression of CCR1, may be linked to the progression of LGBLEL into lymphoma.

A novel murine syngeneic CD8 peripheral T-cell lymphoma model with preclinical applications

Peripheral T-cell Lymphoma (PTCL) represents a heterogenous group of aggressive non-Hodgkin Lymphomas with poor prognostic outcomes and limited treatment options. The development and refinement of therapeutic strategies for PTCL are impeded by a paucity of reliable preclinical models that accurately mimic the disease’s pathophysiology. There is a dire need for more physiologically relevant models for PTCL. Here we describe a spontaneousCD8+ peripheral T-cell lymphoma cell line (LM-23) derived from a 12-week-old female Balb/cJ mouse. Both intravenous and subcutaneous administration of this cell line to syngeneic Balb/cJ mice resulted in rapid establishment of tumor growth. CHOP and anti-PD1 treatment both displayed no benefit to mice in regulating tumor growth. Such results along with its phenotypic characteristics, rapid growth, and metastatic behavior in syngeneic mice highlight its value in studying the elusive disease and discovery of novel therapeutics.

A case of diffused large B-cell lymphoma in an elderly patient successfully treated with R-mini-CHOP

Diffuse large B-cell lymphoma (DLBCL) is a diverse group of B-cell lymphomas that vary in their clinical characteristics. Usually manifesting as a rapidly progressing or advanced condition, it is often curable even at advanced stages. The illness originates in extranodal and extramedullary tissues in 40% of patients. Patients over the age of 80 who have comorbidities or fragile conditions may be eligible for Rituximab and Reduced Dose CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) (R-mini-CHOP) chemoimmunotherapy. We report a 75-year-old woman with a tumor on the right side of the nose that covers the eye, so it is easy to fall out. The diagnosis of DLBCL (sinonasal) was made on the basis of computed tomography (CT) scan of the paranasal sinuses with contrast and immunohistochemical examination. Due to the age of the patient, who was included in the very elderly category with moderate frailty based on instrumental activities of daily living (IADLs), the patient was given R-mini-CHOP chemoimmunotherapy for six cycles, followed by radiation as much as 20 × 18 Gray (Gy) where the patient in the final evaluation stated complete response.

Ibrutinib plus rituximab and mini-CHOP in older patients with newly diagnosed DLBCL: a phase 2 ALLG study

AbstractThe multicenter, prospective phase 2 Australasian Leukaemia & Lymphoma Group NHL29 trial was conducted to assess the addition of ibrutinib to R-mini-CHOP (dose attenuated R-CHOP; rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) in patients aged ≥75 years with newly diagnosed diffuse large B-cell lymphoma (DLBCL). Treatment consisted of six 21-day cycles of ibrutinib–R-mini-CHOP followed by two 21-day cycles of R-ibrutinib. Coprimary end points were deliverability and 2-year overall survival (OS). The median average relative total dose and average relative dose intensity for the entire regimen were both 97% (interquartile range, 82-100 and 88-100, respectively). With a median follow-up of 35.5 months, the 2-year OS was 68% (95% confidence interval [CI], 55.6-77.4) with a 2-year progression-free survival (PFS) of 60.0% (95% CI, 47.7-70.3). Median OS and PFS were 72 months (95% CI, 35 to not reached) and 40 months (95% CI, 20.4 to not reached), respectively. The overall response rate was 76% (61/79) of patients, with a complete response rate of 71% (56/79). Deaths occurred in 34 of 79 patients (43%), including 17 from progressive disease and 5 treatment related. Overall, 67% patients experienced at least 1 serious adverse event. Most common adverse events were infections and diarrhea (the majority grade 1-2). In both health-related quality of life measures, there was an improvement in functional and symptom scales, median health state classification score, and median visual analogue scale in responders over time. In conclusion, this study showed that the addition of ibrutinib to R-mini-CHOP was both deliverable and efficacious in elderly DLBCL patients.

Diagnostic genomic analysis is prognostic in AYA patients with ALL treated on an MRD-stratified pediatric protocol

AbstractOver the last decade, next-generation sequencing has enabled classification of multiple new recurrent genomic drivers of acute lymphoblastic leukemia (ALL). The aim of this study was to describe the genomic drivers of ALL in an adolescent and young adult (AYA) cohort (ALL06; target age, 15-39 years; recruited age, 16.6-39 years), treated uniformly on a pediatric-inspired protocol (the Australasian Leukaemia and Lymphoma Group ALL06 study). ALL06 assessed the safety and efficacy of adapting a pediatric chemotherapy protocol in older patients. Genomic risk classification of patients with B-cell ALL (B-ALL) and T-cell ALL (T-ALL) enrolled to the study was based on the use of multiple assays: messenger RNA sequencing, multiplex ligation-dependent probe amplification, immunophenotyping, and cytogenetics. Using this approach, 36 of 40 (90%) patients with B-ALL and 13 of 17 (76.5%) patients with T-ALL were classified according to genomic risk. A strong correlation existed between adverse genomic risk and minimal residual disease (MRD) at the end of consolidation, translating to inferior overall and relapse free survival. Patients with adverse risk genomics who achieved negative MRD status had improved responses compared with those with persistent MRD. Patients with standard-risk genomics had excellent responses regardless of MRD status. This is, to our knowledge, the first report of the impact of genomics in an individual cohort of AYA patients treated on a single protocol. These data argue strongly for incorporation of a genomic risk classification into future ALL treatment paradigms at the time of diagnosis, and also for the rigorous assessment of risk assignments in a group of patients who are not children and not older adults.

Kinases Inhibitors as New Therapeutic Opportunities in Cutaneous T-Cell Lymphoma

Cutaneous T-cell lymphomas (CTCLs) are a heterogeneous group of T-cell lymphomas characterised by high relapse rates and no curative treatments unless the allogeneic stem cell transplantation. The main complication in the management of this kind of malignancy is the variability that characterises the genetic and clinical features among the CTCL subtypes. JAK/STAT, MAPK/ERK, PI3K/Akt, and NF-kB are those signalling pathways that are found altered in CTCL and that are responsible for promoting both T-cell malignancy and the pro-tumorigenic microenvironment. Thus, targeting key players of these pathways can be an advantageous therapeutic option for CTCL. In this review, we aim to summarise the different approaches that precisely inhibit the kinases of each cited signalling. JAK inhibitors seem to be the most promising kinase inhibitors for CTCL. However, adverse events have been reported especially in patients with immunosuppression or an underlying autoimmune disease. More studies are needed, especially clinical trials, to investigate the benefits of these drugs for the treatment of cutaneous T-cell lymphomas.

Can computed tomography findings and radiomics analysis of mediastinal lymph nodes differentiate between sarcoidosis and lymphoma?

To assess the ability of computed tomography (CT) findings and radiomics analysis to differentiate mediastinal lymphadenopathies as sarcoidosis versus lymphoma. 94 patients with lymphoma and 97 patients with sarcoidosis, who had > 1cm mediastinal lymph node were included. Size, location of lymph nodes, and distribution of the largest lymph nodes in two groups were compared. A total of 636 lymphadenopathies in four different regions were segmented for radiomics. Lesion segmentation was semiautomatically performed with a dedicated commercial software package on chest CT images. 149 patients were grouped as a training cohort, while 42 patients who underwent CT in the oncology hospital were used for external validation. The least absolute shrinkage and selection operator (LASSO) analysis was used to perform feature selection. Using selected features, the classification performance of various data mining methods in separating groups of sarcoidosis and lymphoma was investigated. Distribution and size of lymphadenopathies were significantly different in sarcoidosis and lymphoma groups (<0.05). Radiomics and data mining methods showed excellent performance in differentiating lymph nodes of sarcoidosis and lymphoma according to both the largest lymphadenopathy and lymphadenopathies in four different mediastinal regions (AUC >0,95). Distribution and size of lymphadenopathies can help differential diagnosis in patients with sarcoidosis and lymphoma. CT radiomics analysis can discriminate the lymph nodes of sarcoidosis and lymphoma with great performance regardless of lymph node size and location and it can be used safely in the diagnosis of these diseases, which can sometimes be challenging to distinguish from each other.

Identification and evolution of predictors of Sjögren's disease-associated mucosa-associated lymphoid tissue lymphoma development over time: a case-control study

Non-Hodgkin lymphomas have a substantial impact on individuals with Sjögren's disease. This study focuses on mucosal-associated lymphoid tissue (MALT) lymphomas, which constitute the majority of Sjögren's disease-associated non-Hodgkin lymphomas. We aimed to identify reliable lymphoma predictors in patients with Sjögren's disease and study their progression over time. In this case-control study, patients diagnosed with Sjögren's disease-associated MALT lymphoma, with a minimum of 3 years between Sjögren's disease diagnosis and MALT lymphoma diagnosis, were included from three centres specialising in Sjögren's disease (University of Athens, Athens, Greece; University of Pisa, Pisa, Italy; and University of Udine, Udine, Italy) and matched 1:1 with control participants with Sjögren's disease who did not have lymphoma according to age, sex, disease duration at last follow up, and treatment modality. Three harmonised datasets were constructed, curated, and analysed to identify MALT lymphoma predictors, representing three distinct timepoints in lymphomagenesis progression: V1 at Sjögren's disease diagnosis, V2 3-4 years before lymphoma diagnosis, and V3 0·5-1·5 years before lymphoma diagnosis. All recruited patients fulfilled the 2016 American College of Rheumatology-European League Against Rheumatism criteria for Sjögren's disease. The primary outcome was to identify MALT lymphoma predictors in Sjögren's disease, present at the timepoint of Sjögren's disease diagnosis and 3-4 years before the diagnosis of MALT lymphoma. A fast correlation-based feature selection and logistic regression model was used at V1 and V2 to identify MALT lymphoma predictors. The progression of potential predictors was studied across V1, V2, and V3. Histological parameters were not included in the analysis. An individual with lived experience of Sjögren's disease was involved in the study design. 80 patients with Sjögren's disease-associated MALT lymphoma were included in the V1 dataset, 68 in the V2 dataset, and 80 in the V3 dataset, and matched to control participants with Sjögren's disease who did not have lymphoma. In both groups, 72 (90%) of 80 participants were women and eight (10%) were men. The mean age at Sjögren's disease diagnosis was 48·6 years (SD 11·6) in the lymphoma group and 48·7 years (11·5) in the control group. All patients were White, with 88 (55%) of 160 individuals of Greek nationality and 72 (45%) of Italian nationality. At the V1 timepoint, rheumatoid factor was the only independent lymphoma predictor (odds ratio 3·33 [95% CI 1·96-5·64]). At the V2 timepoint, rheumatoid factor (3·66 [95% CI 2·08-6·42]) and European League Against Rheumatism Sjögren's Syndrome Disease Activity Index ≥5 (3·88 [1·69-8·90]) were identified as independent lymphoma risk factors. The high disease activity during the transition from the V1 to V2 timepoint was attributed to specific B-cell-derived manifestations, including cryoglobulinaemia and glandular, cutaneous, and hematological manifestations. Following up patients with high-risk of Sjögren's disease-associated MALT lymphoma based on the temporal progression of predictors presents an opportunity for early diagnosis and potential therapeutic interventions. Rheumatoid factor was the earliest and most persistent independent predictor of lymphoma. Specific B-cell manifestations in combination with rheumatoid factor indicate a more advanced stage of the lymphomagenesis process. European Commission-Horizon 2020.

Asciminib monotherapy as frontline treatment of chronic phase chronic myeloid leukemia: results from the ASCEND study

AbstractAsciminib is a myristoyl site BCR::ABL1 inhibitor approved for patients with chronic phase chronic myeloid leukemia (CP-CML) failing ≥2 prior lines of therapy. The Australasian Leukaemia and Lymphoma Group conducted the Asciminib Evaluation in Newly Diagnosed CML study to assess efficacy of asciminib for newly diagnosed CP-CML. Patients commenced asciminib 40 mg twice daily. Patients with treatment failure, defined as BCR::ABL1 of >10% at 3 or 6 months, or >1% at 12 or 18 months, received either imatinib, nilotinib, or dasatinib in addition to asciminib. In patients with suboptimal response, defined as levels of 1% to 10% at 6 months, >0.1% to 1% at 12 months, or >0.01% to 1% at 18 months, the asciminib dose was increased to 80 mg twice daily. With a median follow-up of 21 months (range, 0-36), 82 of 101 patients continue asciminib. Most common reasons for treatment discontinuation were adverse events (6%), loss of response (4%), and withdrawn consent (5%). There were no deaths; 1 patient developed lymphoid blast crisis. The coprimary end points were early molecular response (BCR::ABL1 of ≤10% at 3 months), achieved in 93% (96% confidence interval [CI], 86-97%), and major molecular response by 12 months achieved in 79%; (95% CI, 70-87%), respectively. Cumulative incidence of molecular response 4.5 was 53% by 24 months. One patient had 2 cerebrovascular events; no other arterial occlusive events were reported. Asciminib as frontline CP-CML therapy leads to high rates of molecular response with excellent tolerance and a low rate of discontinuation for toxicity.

Exploring the educational needs of patients with cutaneous lymphoma using an educational needs assessment tool.

Cutaneous T-cell lymphomas (CTCL) are a group of rare non-Hodgkin lymphomas characterized by initial localization of malignant T-lymphocytes in the skin. Support and information from nurses and patient support groups have proven useful for patients with CTCL, but little is known about the educational needs of these patients. To investigate the self-reported educational needs among CTCL patients using an educational needs assessment tool and to explore differences related to sex, age, disease duration, clinical stage, and education. This observational single center study analyzed 70 patients with CTCL in routine dermatological outpatient care. The patients were asked to complete a questionnaire to capture their educational needs in regard to CTCL. The questionnaire was inspired by the educational needs assessment tool, designed and validated for patients with rheumatoid disease. The questionnaire included a general question, "In general, how much information do you want to receive about your lymphoma disease?", and five domains covering information relating to disease process (6 items), treatment (4 items), feelings (2 items), self-management of itch, sleep, and rest (2 items), and support systems (3 items). The domain scores ranged from 0 to 18 and the total score from 0 to 51, with a higher score indicating a greater need for education. When asked "In general, how much information do you need?", females wanted to know more compared with males (2.6 vs. 2.1, p=0.006), and patients with higher education wanted to know more than patients with lower education (2.5 vs. 2.0, p=0.025). The domains concerning treatment (80%) and disease process (75%) revealed the greatest needs for education. Patients with a disease duration <2 years reported a greater educational need for the domain support system, compared with patients with longer disease duration. Patients with lower education reported a greater educational need about feelings compared with patients with higher education. We found that 65% of the CTCL patients in the cohort, particularly females, expressed a need for education, especially regarding disease process and treatment. A deeper understanding of the educational needs would enable healthcare providers to give personalized information.

Clinical characteristics and outcome of early-stage diffuse large B cell lymphoma of female genital track: A retrospective study of the Hellenic cooperative lymphoma group.

Involvement of female genital track (FGT) by diffuse large B cell lymphoma (DLBCL) represents an extremely rare diagnosis. Especially data regarding early-stage disease (i.e., IE, IIE) is very limited. Importantly, previous studies showed controversial results about the risk of central nervous system (CNS) relapse in this entity. Herein, we describe one of the largest reported real-world series of patients with early-stage FGT DLBCL aiming to investigate the clinicopathological characteristics, response to therapy and survival outcomes in the era of immunochemotherapy. We analyzed 21 consecutive patients with biopsy proven DLBCL from uterus or ovary classified as stage IE or IIE out of 1905 newly diagnosed DLBCL patients (1.1%). Uterine and ovarian localization was observed in 14 and seven patients, respectively. Median age was 66years (range 33-96); 9/21 (43%) were <55years. Regarding Cell of Origin DLBCL subtype, Germinal Center B-cell subtype was found in seven patients, non-GCB in 10 and non-classified in 4 patients. Median follow-up was 57months and 5-year overall survival, lymphoma specific survival and Freedom from Progression were 78%, 89% and 90%, respectively. There was no correlation of patients' characteristics with survival parameters. Interestingly, none of the patients experienced CNS relapse. Our results indicate that localized FGT DLBCL exhibits a good prognosis and may not increase the risk for secondary CNS involvement.
