RESUMO
Epstein-Barr virus (EBV) may cause a wide spectrum of symptomatology in humans ranging from asymptomatic upper respiratory tract infection to infectious mononucleosis and in more severe cases lymphoproliferative disorders or hemophagocytic lymphohistiocytosis. Its neoplastic potential is higher in immunocompromised individuals. We describe a case of EBV-positive mucocutaneous ulcer, a more indolent clinical entity on the spectrum of EBV-driven lymphoproliferative disorders, and are one of the first to put sulfasalazine, an immunomodulatory agent, forward as the possible culprit.
RESUMO
ABSTRACT: Optimal treatment in patients with refractory or relapsed peripheral T-cell lymphomas (R/R T-NHLs) is unknown. In this population-based study, outcomes in R/R peripheral T-cell lymphoma not otherwise specified (PTCL NOS), angioimmunoblastic T-cell lymphoma (AITL), and anaplastic lymphoma kinase-positive (ALK+) and ALK-negative (ALK-) anaplastic large cell lymphoma (ALCL) were evaluated. Patients with PTCL NOS, AITL, ALK+ ALCL, and ALK- ALCL (≥18 years) diagnosed in 2014 to 2019 were identified using the Netherlands Cancer Registry. End points were overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). The 2-year PFS of 821 patients was 57%. Among 311 patients with a relapse, 243 received second-line treatment: 44% received salvage chemotherapy, 20% received brentuximab vedotin (BV), and 36% received other treatment. In third-line treatment, BV was most commonly used (38%). ORR after second-line treatment was 47%. Two-year PFS and OS after relapse were 25% and 34%, respectively. The risk of second relapse was negatively affected by early relapse (<12 months after diagnosis), whereas BV reduced this risk compared with salvage chemotherapy. Reduced risk of relapse was independent of histological subtype. The best outcomes were observed for patients treated with salvage chemotherapy receiving consolidative autologous and allogeneic stem cell transplantation (SCT) (2-year OS 68%), patients treated with BV achieving a second complete remission (2-year OS 74%) and patients with allogeneic SCT (2-year OS 60%). The risk of second relapse was significantly lower for patients with R/R T-NHL treated with BV compared with patients treated with salvage chemotherapy, and this was irrespective of subtype. Therefore, the use of salvage chemotherapy for patients with R/R T-NHL is challenged.

Peripheral T-cell lymphomas (PTCL) comprise a heterogeneous group of mature T-cell neoplasms with an unfavorable prognosis; presentation with stage I(E) disease is uncommon. In clinical practice, an abbreviated chemotherapy treatment regimen combined with radiotherapy (combined modality treatment [CMT]) is commonly used, although evidence from clinical trials is lacking. The aim of this nationwide population-based cohort study is to describe first-line treatment and outcome of patients with stage I(E) PTCL. All newly diagnosed patients ≥18 years with stage I(E) anaplastic large cell lymphoma (ALCL), angioimmunoblastic T-cell lymphoma (AITL) and peripheral T-cell lymphoma NOS (PTCL not otherise specified [NOS]) in 1989-2020 were identified in the Netherlands Cancer Registry. Patients were categorized according to treatment regimen, i.e., chemotherapy (CT), radiotherapy (RT), CMT, other therapy and no treatment. The primary endpoint was overall survival (OS). Patients with stage I(E) ALCL, AITL and PTCL NOS (n=576) were most commonly treated with CMT (28%) or CT (29%), 2% underwent SCT. RT only was given in 18%, and 8% received other therapy and 16% no treatment. Overall, the 5-year OS was 59%. According to subtype, 5-year OS was superior for ALCL as compared to PTCL NOS and AITL (68% vs. 55% and 52%, respectively; P=0.03). For patients treated with CMT, 5-year OS was significantly higher (72%) as compared to patients treated with either CT or RT alone (55% and 55%, respectively; P<0.01). In multivariable analysis, age per year increment (hazard ratio [HR] =1.06, 95% confidence interval [CI]: 1.05-1.07), male sex (HR=1.53, 95% CI: 1.23-1.90), and CT, or no treatment (HR=1.64, 95% CI: 1.21-2.21, and HR=1.55, 95% CI: 1.10-2.17, respectively) were associated with a higher risk of mortality. For stage I(E) ALCL, AITL and PTCL NOS, 5-year OS is 59%, comparing favorably to historical outcome in advanced-stage disease. Superior outcome estimates were observed in patients treated with CMT.

BACKGROUND: Uveal melanoma is an orphan malignancy with very limited data on treatment options in metastatic setting. METHODS: In this single-center retrospective study, we describe real-world epidemiological and survival data on 121 metastatic uveal melanoma (MUM) patients registered in our institution. As a large tertiary referral center, almost 30% of all diagnoses in the Flemish region of Belgium were covered. Primarily, we determined whether introduction of immune checkpoint inhibitors (ICI) led to improved overall survival (OS) in MUM patients. Secondarily, response rates to ICI were assessed and we evaluated whether first-line ICI could be a valid alternative to liver-directed therapy (LDT) in liver-only disease. RESULTS: The initially perceived 10.8 months survival benefit from treatment with ICI disappeared after correction for immortality bias. By analyzing treatment type as time-varying covariate on OS, no significant benefit of ICI over other systemic therapies (HR = 0.771) or best supportive care (BSC) (HR = 0.780) was found. Also comparison of the pre-ICI versus ICI era showed no OS improvement after introduction of ICI in our center (p = 0.7994). Only liver-directed and local oligometastatic approaches were associated with a lower chance of mortality when compared to ICI (p = 0.0025), other systemic therapies (p = 0.0001) and BSC (p = 0.0003), yet without correction for selection bias. We reported overall response rates on ICI ranging from 8-15% and we found some support for neoadjuvant strategies with ICI resulting in remission or downsizing, allowing oligometastatic approaches later on. In first-line liver-only disease, median real-world progression-free survival and OS did not significantly differ between patients treated with LDT or ICI upfront (p = 0.2930 and p = 0.5461 respectively). CONCLUSION: Although we documented responses to ICI, our analyses do not demonstrate an OS benefit of ICI over alternative treatment strategies for MUM. However, local treatment options, whether liver-directed or for oligometastatic disease, may be beneficial and should be considered.

Several studies have shown a strong predictive value for pretreatment [18F]FDG-PET/CT metabolic parameters in different lymphoma subtypes. However, few publications exist concerning the role of metabolic parameters in mantle cell lymphoma (MCL). We retrospectively investigated the prognostic value of baseline metabolic tumor volume (MTV) and lesion dissemination in untreated MCL. We compared it to currently used prognostic factors such as stage, mantle cell lymphoma international prognostic index (MIPI) and KI-67. We report that a higher baseline MTV is a risk factor for worse overall survival (OS), progression-free survival (PFS), and disease-specific survival (DSS) in univariate analysis. In multivariate analysis, MTV was significantly associated with DSS, but not with OS and PFS. We found no correlation between lesion dissemination and outcome. The MIPI score remains the strongest predictor of outcome. These results show that MTV is an important prognostic tool and can improve patient risk stratification at staging of untreated MCL.

BACKGROUND AND PURPOSE: Enterovirus infections pose a serious threat for patients with humoral deficiencies and may be lethal, whilst the efficacy of proposed treatment options such as corticosteroids, intravenous immunoglobulins and fluoxetine remains debated. METHODS: Viral clearance was investigated in a patient with rituximab-induced B-cell depletion and chronic echovirus 13 (E13) meningoencephalitis/myofasciitis in response to intravenous immunoglobulins and fluoxetine using sequential semi-quantitative E13 viral load measurements by real-time reverse transcription polymerase chain reaction. Fluoxetine concentrations in plasma and cerebrospinal fluid were determined by liquid chromatography mass spectrometry. RESULTS: Intravenous immunoglobulins appeared ineffective in this case of E13 infection, whereas virus clearance in cerebrospinal fluid was obtained after 167 days of oral fluoxetine. Since treatment with corticosteroids resulted in a flare of symptoms, rechallenge with viral load measurements was not attempted. CONCLUSION: In this report of a patient with rituximab-associated chronic echovirus 13 meningoencephalitis, viral clearance in response to single treatment options is assessed for the first time. Our observations further support the in vivo efficacy of fluoxetine against enteroviral infections. More research is needed to establish its efficacy in different enterovirus strains.

Patients aged <65 years with peripheral T-cell lymphoma (PTCL) are treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). Although the addition of etoposide (CHOEP) and consolidation with autologous stem cell transplantation (ASCT) are preferred in some countries, randomized trials are lacking. This nationwide population-based study assessed the impact of etoposide and ASCT on overall survival (OS) among patients aged 18 to 64 years with stage II to IV anaplastic large-cell lymphoma (ALCL), angioimmunoblastic T-cell lymphoma (AITL), or PTCL not otherwise specified (NOS) diagnosed between 1989 and 2018 using the Netherlands Cancer Registry. Patients were categorized into 2 calendar periods, representing pre- and post-eras of etoposide and ASCT, respectively. A total of 1427 patients were identified (ALCL, 35%; AITL, 21%; and PTCL NOS, 44%). OS increased from 39% in the period from 1989 to 2009 to 49% in the period of 2009 to 2018 (P < .01). Five-year OS was superior for patients treated with CHOEP vs CHOP (64% and 44%, respectively; P < .01). When adjusted for subtype, International Prognostic Index score, and ASCT, the risk of mortality was similar between the 2 groups, except for patients with ALK+ ALCL, for whom the risk of mortality was 6.3 times higher when treated with CHOP vs CHOEP. Patients undergoing consolidation with ASCT had superior 5-year OS of 81% compared with 39% for patients not undergoing ASCT (P < .01), regardless of whether complete remission was achieved. In patients aged <65 years with advanced-stage ALK- ALCL, AITL, or PTCL, the use of ASCT consolidation, but not the addition of etoposide, was associated with improved OS.

Gene-expression profiling (GEP) is used to study the molecular biology of lymphomas. Here, advancing insights from GEP studies in diffuse large B-cell lymphoma (DLBCL) lymphomagenesis are discussed. GEP studies elucidated subtypes based on cell-of-origin principles and profoundly changed the biological understanding of DLBCL with clinical relevance. Studies integrating GEP and next-generation DNA sequencing defined different molecular subtypes of DLBCL entities originating at specific anatomical localizations. With the emergence of high-throughput technologies, the tumor microenvironment (TME) has been recognized as a critical component in DLBCL pathogenesis. TME studies have characterized so-called "lymphoma microenvironments" and "ecotypes". Despite gained insights, unexplained chemo-refractoriness in DLBCL remains. To further elucidate the complex biology of DLBCL, we propose a novel targeted GEP consortium panel, called BLYM-777. This knowledge-based biology-driven panel includes probes for 777 genes, covering many aspects regarding B-cell lymphomagenesis (f.e., MYC signature, TME, immune surveillance and resistance to CAR T-cell therapy). Regarding lymphomagenesis, upcoming DLBCL studies need to incorporate genomic and transcriptomic approaches with proteomic methods and correlate these multi-omics data with patient characteristics of well-defined and homogeneous cohorts. This multilayered methodology potentially enhances diagnostic classification of DLBCL subtypes, prognostication, and the development of novel targeted therapeutic strategies.
RESUMO
ALK-positive histiocytosis is a rare subtype of histiocytic neoplasm first described in 2008 in 3 infants with multisystemic disease involving the liver and hematopoietic system. This entity has subsequently been documented in case reports and series to occupy a wider clinicopathologic spectrum with recurrent KIF5B-ALK fusions. The full clinicopathologic and molecular spectra of ALK-positive histiocytosis remain, however, poorly characterized. Here, we describe the largest study of ALK-positive histiocytosis to date, with detailed clinicopathologic data of 39 cases, including 37 cases with confirmed ALK rearrangements. The clinical spectrum comprised distinct clinical phenotypic groups: infants with multisystemic disease with liver and hematopoietic involvement, as originally described (Group 1A: 6/39), other patients with multisystemic disease (Group 1B: 10/39), and patients with single-system disease (Group 2: 23/39). Nineteen patients of the entire cohort (49%) had neurologic involvement (7 and 12 from Groups 1B and 2, respectively). Histology included classic xanthogranuloma features in almost one-third of cases, whereas the majority displayed a more densely cellular, monomorphic appearance without lipidized histiocytes but sometimes more spindled or epithelioid morphology. Neoplastic histiocytes were positive for macrophage markers and often conferred strong expression of phosphorylated extracellular signal-regulated kinase, confirming MAPK pathway activation. KIF5B-ALK fusions were detected in 27 patients, whereas CLTC-ALK, TPM3-ALK, TFG-ALK, EML4-ALK, and DCTN1-ALK fusions were identified in single cases. Robust and durable responses were observed in 11/11 patients treated with ALK inhibition, 10 with neurologic involvement. This study presents the existing clinicopathologic and molecular landscape of ALK-positive histiocytosis and provides guidance for the clinical management of this emerging histiocytic entity.

BACKGROUND: Hepatocellular carcinoma (HCC) recurrence rates following locoregional treatment are high. As multireceptor tyrosine kinase inhibitors targeting vascular endothelial growth factor receptors (VEGFRs) are effective in advanced HCC, we assessed the efficacy and safety of neoadjuvant systemic treatment with dovitinib in early- and intermediate-stage HCC. MATERIALS AND METHODS: Twenty-four patients with modified Child-Pugh class A early- and intermediate-stage HCC received neoadjuvant oral dovitinib 500 mg daily (5 days on/2 days off) for 4 weeks, followed by locoregional therapy. Primary endpoints were objective response rates and intratumoral blood flow changes. Secondary endpoints were safety, pharmacodynamical plasma markers of VEGFR-blockade, time to progression (TTP), and overall survival (OS). RESULTS: Modified RECIST overall response rate was 48%, including 13% complete remission, and despite dose reduction/interruption in 83% of patients, intratumoral perfusion index decreased significantly. Grade 3-4 adverse events, most frequently (on-target) hypertension (54%), fatigue (25%), and thrombocytopenia (21%), occurred in 88% of patients. Plasma VEGF-A, VEGF-D, and placental growth factor increased significantly, whereas sTie-2 decreased, consistent with VEGFR-blockade. Following neoadjuvant dovitinib, all patients could proceed to their original planned locoregional treatment. No delayed toxicity occurred. Seven patients (three early, four intermediate stage) underwent orthotopic liver transplant after median 11.4 months. Censoring at transplantation, median TTP and OS were 16.8 and 34.8 months respectively; median cancer-specific survival was not reached. CONCLUSION: Already after a short 4-week dovitinib treatment period, intratumoral blood flow reduction and modest antitumor responses were observed. Although these results support use of systemic neoadjuvant strategies, the poor tolerability indicates that dovitinib dose adaptations are required in HCC. IMPLICATIONS FOR PRACTICE: Orthotopic liver transplantation may cure early and intermediate-stage hepatocellular carcinoma. Considering the expected waiting time >6 months because of donor liver scarcity, there is an unmet need for effective neoadjuvant downsizing strategies. Angiogenesis inhibition by dovitinib does not negatively affect subsequent invasive procedures, is safe to administer immediately before locoregional therapy, and may provide a novel treatment approach to improve patient outcomes if tolerability in patients with hepatocellular carcinoma can be improved by therapeutic drug monitoring and personalized dosing.

Recently, a novel disorder coined VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome was identified in patients with adult-onset inflammatory syndromes, often accompanied by myelodysplastic syndrome1. All patients had myeloid lineage-restricted somatic mutations in UBA1 affecting the Met41 residue of the protein and resulting in decreased cellular ubiquitylation activity and hyperinflammation. We here describe the clinical disease course of two VEXAS syndrome patients with somatic UBA1 mutations of which one with a mild phenotype characterized by recurrent rash and symmetric polyarthritis, and another who was initially diagnosed with idiopathic multicentric Castleman disease and developed macrophage activation syndrome as a complication of the VEXAS syndrome. The latter patients was treated with anti-IL6 therapy (siltuximab) leading to a resolution of systemic symptoms and reduction of transfusion requirements.

A 35-year-old woman underwent bilateral lung transplantation for primary ciliary dyskinesia and developed vascular tumors over a slow time course. Initial presentation of non-specific vascular tumors in the lungs and liver for up to 6 years after transplantation evolved toward bilateral ovarian angiosarcoma. Tumor analysis by haplotyping and human leukocyte antigen typing showed mixed donor chimerism, proving donor origin of the tumoral lesions. In retrospect, the donor became brain dead following neurosurgical complications for a previously biopsy-proven cerebral hemangioma, which is believed to have been a precursor lesion of the vascular malignancy in the recipient. Donor-transmitted tumors should always be suspected in solid organ transplant recipients in case of uncommon disease course or histology, and proper tissue-based diagnosis using sensitive techniques should be pursued.

This cohort study of the International Network on Cancer, Infertility and Pregnancy (INCIP) reports the maternal and neonatal outcomes of 80 pregnant patients diagnosed with non-Hodgkin lymphoma (NHL) between 1986 and 2019, focussing on 57 (71%) patients with diffuse large B-cell lymphoma (DLBCL). Of all 80 patients, 54 (68%) pregnant patients received chemotherapy; mostly (89%) CHOP-like (cyclophosphamide, doxorubicin, vincristine, and prednisone) regimens. Four early pregnancies were terminated. Among 76 ongoing pregnancies, there was one stillbirth (1·3%). Overall, there was a high incidence of small for gestational age neonates (39%), preterm delivery (52%), obstetric (41%) and neonatal complications (12·5%), and this could not exclusively be explained by the receipt of antenatal chemotherapy. Half of preterm deliveries (46%) were planned in order to tailor oncological treatment. The 3-year progression-free and overall survival for patients with DLBCL treated with rituximab-CHOP was 83·4% and 95·7% for limited stage (n = 29) and 60·6% and 73·3% for advanced stage (n = 15). Of 36 pregnant patients who received rituximab, five (13%) cases with neonatal complications and three (8%) with maternal infections were reported. In conclusion, standard treatment for DLBCL can be offered to pregnant patients in obstetric centres that cater for high-risk patients.

BACKGROUND: Limited data exist on transfusion burden and transfusion-related iron overload in adult survivors of solid malignancies. METHODS: Hospital-specific cancer registry data of patients with solid tumor receiving systemic anticancer treatment between January 2008 and September 2009 at the Oncology Department of the Leiden University Medical Center (The Netherlands) were retrieved and cross-referenced with red blood cell (RBC) transfusion records. Individual lifetime transfusion burden was captured in April 2015. Multitransfused long-term survivors with serum ferritin >500 µg/L were subsequently screened for hepatic and cardiac iron overload using 1.5 Tesla magnetic resonance imaging. RESULTS: The study population consisted of 775 adult patients with solid cancer (45.2% male; median age, 58 years; >75% chemotherapy-treated), 423 (54.6%) of whom were transfused with a median of 6.0 RBC units (range 1-67). Transfusion triggers were symptomatic anemia or hemoglobin <8.1-8.9 g/dL prior to each myelosuppressive chemotherapy cycle. We identified 123 (15.9%) patients across all tumor types with a lifetime transfusion burden of ≥10 RBC units. In the absence of a hemovigilance program, none of these multitransfused patients was screened for iron overload despite a median survival of 4.6 years. In 2015 at disclosure of transfusion burden, 26 multitransfused patients were alive. Six (23.1%) had hepatic iron overload: 3.9-11.2 mg Fe/g dry weight. No cardiac iron depositions were found. CONCLUSION: Patients with solid malignancies are at risk for multitransfusion and iron overload even when adhering to restrictive RBC transfusion policies. With improved long-term cancer survivorship, increased awareness of iatrogenic side effects of supportive therapy and development of evidence-based guidelines are essential. IMPLICATIONS FOR PRACTICE: In the presence of a restrictive transfusion policy, â¼30% of transfused adult patients with solid cancer are multitransfused and â¼50% become long-term survivors, underscoring the need for evidence-based guidelines for the detection and management of transfusion-related iron overload in this group of patients. In each institution, a hemovigilance program should be implemented that captures the lifetime cumulative transfusion burden in all patients with cancer, irrespective of tumor type. This instrument will allow timely assessment and treatment of iron overload in cancer survivors, thus preventing organ dysfunction and decreased quality of life.

BACKGROUND: Outcomes for mother and child following a diagnosis of Hodgkin lymphoma during pregnancy are underinvestigated, and antenatal management of the disease has not been reported on widely. The aim of this study was to assess obstetric outcomes, antenatal management, and maternal survival in patients with Hodgkin lymphoma diagnosed during pregnancy who were registered in the International Network on Cancer, Infertility and Pregnancy (INCIP) database. METHODS: We did a multicentre, retrospective cohort study including oncological and obstetric data from 134 pregnant patients diagnosed with Hodgkin lymphoma between Jan 1, 1969, and Aug 1, 2018. Data collected from the INCIP database were obtained from 17 academic centres in Belgium, Czech Republic, Denmark, Greece, Israel, Italy, Mexico, the Netherlands, Russia, the UK, and the USA. We analysed patients' management over three epochs (before 1995, 1995-2004, and 2005-18). Obstetric outcomes (birthweight, obstetric or neonatal complications, and admission to a neonatal intensive care unit [NICU]) of patients who received antenatal chemotherapy were compared to those of patients who did not receive antenatal treatment. Maternal progression-free and overall survival was assessed by disease stage at diagnosis in pregnant patients and compared with outcomes of non-pregnant patients with Hodgkin lymphoma selected from databases of three tertiary centres, matched for stage and prognostic score. All patients included in survival analyses received standard doxorubicin, bleomycin, vinblastine and dacarbazone (ABVD) therapy since Jan 1, 1997. FINDINGS: Of the 134 pregnant patients diagnosed with Hodgkin lymphoma during pregnancy. 72 (54%) patients initiated antenatal chemotherapy, 56 (42%) did not receive treatment during pregnancy, and 6 (4%) received only radiotherapy. Over the years, chemotherapy was increasingly commenced during pregnancy. The incidence of neonates who were small for gestational age did not differ between chemotherapy-exposed neonates (15 [22%] of 69) and non-exposed neonates (six [16%] of 42; p=0·455). Admission to NICU also did not differ between groups (19 [29%] exposed to antenatal chemotherapy vs 12 [35%] unexposed to antenatal chemotherapy). Birthweight percentiles were lower in neonates prenatally exposed to chemotherapy compared with non-exposed neonates (p=0·035). Patients receiving antenatal therapy had more obstetric complications than those without antenatal therapy (p=0·005), the most common complications being preterm contractions (nine [12%] vs three [7%]) and preterm rupture of membranes (four [5%] vs 0). For the maternal survival analyses, we compared 77 pregnant patients and 211 non-pregnant, matched controls. 5-year progression-free survival for patients with early-stage Hodgkin lymphoma was 82·6% (95% CI 67·4-91·1) for 62 pregnant patients and 88·3% (81·6-92·7) for 142 controls (hazard ratio [HR] 1·80, 95% CI 0·84-3·87; p=0·130; 5-year overall survival was 97·3% (82·3-99·6) and 98·4% (93·6-99·6; HR 1·63, 0·35-7·65; p=0·534). In patients with advanced-stage disease (15 pregnant patients and 69 non-pregnant controls), 5-year progression-free survival was 90·9% (95% CI 50·8-98·7) versus 74·0% (60·9-83·3); HR 0·36, 95% CI 0·04-2·90; p=0·334. 5-year overall survival was 100% (no events occurred) and 96·2% (95% CI 85·5-99·1; HR cannot be estimated; p=0·146). INTERPRETATION: Occurrence of preterm contractions or preterm rupture of membranes was higher in patients with Hodgkin lymphoma receiving antenatal treatment compared with those who did not initiate treatment during pregnancy. Maternal survival did not differ between pregnant and non-pregnant patients with Hodgkin lymphoma, suggesting that antenatal chemotherapy or deferral of treatment until postpartum in selected patients can be considered, with regular obstetric follow-up to safeguard foetal growth.
