RESUMEN
Cardiovascular diseases, especially congestive heart failure (CHF), are known complications of anthracyclines, but the risk for patients undergoing high-dose chemotherapy and autologous stem cell transplant (HDT-ASCT) is not well established. With T-cell therapies emerging as alternatives, studies of long-term complications after HDT-ASCT are warranted. Danish patients treated with HDT-ASCT for aggressive lymphoma between 2001 and 2017 were matched 1:5 on sex, birth year and Charlson comorbidity score to the general population. Events were captured using nationwide registers. A total of 787 patients treated with HDT-ASCT were identified. Median follow-up was 7.6 years. The risk of CHF was significantly increased in the HDT-ASCT population compared to matched comparators with an adjusted hazard ratio (HR) of 5.5 (3.8-8.1). The 10-year cumulative incidence of CHF was 8.0% versus 2.0% (p < 0.001). Male sex, ≥2 lines of therapy, hypertension and cumulative anthracycline dose (≥300 mg/m2 ) were risk factors for CHF. In a separate cohort of 4089 lymphoma patients, HDT-ASCT was also significantly associated with increased risk of CHF (adjusted HR of 2.6 [1.8-3.8]) when analysed as a time-dependent exposure. HDT-ASCT also increased the risk of other cardiac diseases. These findings are applicable for the benefit/risk assessment of HDT-ASCT versus novel therapies.

PURPOSE: Etoposide to standard R-CHOP is used for high-risk diffuse large B-cell lymphoma (DLBCL) in some countries. Due to the lack of randomized trials, a real-world data study using matching methods was used to test the potential effectiveness of R-CHOEP over R-CHOP. PATIENTS AND METHODS: This study included patients from the Danish Lymphoma Register diagnosed between 2006 and 2020 at the age of 18-60 years with de novo DLBCL and age-adjusted IPI ≥2. R-CHOEP treated patients were matched 1:1 without replacement to R-CHOP treated patients using a hybrid exact and genetic matching technique. Primary endpoints were progression-free survival (PFS) and overall survival (OS). RESULTS: In total, 396 patients were included; 213 received R-CHOEP and 183 received R-CHOP. Unadjusted 5-year PFS and OS for R-CHOEP were 69% (95% Confidence intervals [CI]; 63%-76%) and 79% (CI;73%-85%) versus 62% (CI;55%-70%) and 76% (CI;69%-82%) for R-CHOP (log-rank test, PFS p = .25 and OS p = .31). A total of 127 patients treated with R-CHOEP were matched to 127 patients treated with R-CHOP. Matching-adjusted 5-year PFS and OS were 65% (CI; 57%-74%) and 79% (CI; 72%-84%) for R-CHOEP versus 63% (CI; 55%-73%) and 79% (CI;72%-87%) for R-CHOP (log-rank test, PFS p = .90 and OS p = .63). CONCLUSION: The present study did not confirm superiority of R-CHOEP over R-CHOP for young patients with high-risk DLBCL.
RESUMEN
Non-endemic Burkitt lymphoma (BL) is a rare germinal centre B-cell-derived malignancy with the genetic hallmark of MYC gene translocation and with rapid tumour growth as a distinct clinical feature. To investigate treatment outcomes, loss of lifetime and relapse risk in adult BL patients treated with intensive immunochemotherapy, retrospective clinic-based and population-based lymphoma registries from six countries were used to identify 264 real-world patients. The median age was 47 years and the majority had advanced-stage disease and elevated LDH. Treatment protocols were R-CODOX-M/IVAC (47%), R-hyper-CVAD (16%), DA-EPOCH-R (11%), R-BFM/GMALL (25%) and other (2%) leading to an overall response rate of 89%. The two-year overall survival and event-free survival were 84% and 80% respectively. For patients in complete remission/unconfirmed, the two-year relapse risk was 6% but diminished to 0·6% for patients reaching 12 months of post-remission event-free survival (pEFS12). The loss of lifetime for pEFS12 patients was 0·4 (95% CI: -0·7 to 2) months. In conclusion, real-world outcomes of adult BL are excellent following intensive immunochemotherapy. For pEFS12 patients, the relapse risk was low and life expectancy similar to that of a general population, which is important information for developing meaningful follow-up strategies with increased focus on survivorship and less focus on routine disease surveillance.

Outcomes for patients with non-Hodgkin's lymphoma (NHL) that proves refractory to treatment remain poor. Treatment of such patients is individualized and can include enrolment in a clinical trial of novel agents or use of one of a wide array of drug regimens. Initial treatment with anthracyclines such as doxorubicin limits options at later stages of treatment because of anthracycline-related cumulative cardiotoxicity. The aza-anthracenedione pixantrone was developed to reduce the likelihood of cardiotoxicity without compromising efficacy and is currently conditionally approved for use as monotherapy in patients with multiply-relapsed or refractory aggressive B cell NHL. The use of pixantrone in combination therapy, often to replace doxorubicin or mitoxantrone, has or is currently being investigated in numerous studies in patients with aggressive or indolent NHL and is the focus of this review. These include the R-CPOP regimen (rituximab, cyclophosphamide, pixantrone, vincristine, prednisone) for aggressive NHL in the first-line setting, including a study in elderly patients with limited cardiac function, and for patients with relapsed NHL with prior anthracycline exposure; the PSHAP regimen (pixantrone, cytarabine, prednisone, cisplatin), also in the latter setting; the PREBen/PEBen regimen (pixantrone, bendamustine and etoposide with or without rituximab) as salvage therapy; and pixantrone in combination with fludarabine, dexamethasone, and rituximab (FPD-R) for relapsed indolent NHL.

BACKGROUND: Second primary malignancies (SPMs) are known complications after chemotherapy, but the risk is not well characterised for patients with lymphoma treated with high-dose chemotherapy and autologous haematopoietic stem-cell transplantation (HSCT). We aimed to investigate the rate of SPMs in this population relative to matched control individuals from the general population. METHODS: In this retrospective, population-based cohort study, patients aged 18 years or older with an aggressive lymphoma who received high-dose chemotherapy and autologous HSCT in Denmark between Jan 1, 2001, and Dec 31, 2017, were included from the Danish Lymphoma Registry and matched (1:5) to control individuals from the general population on birth year and sex via the Danish Civil Registration System. Patients were eligible if they had a registered date of autologous HSCT and patients with primary CNS lymphoma were excluded. Exclusion criteria for both patients and matched control individuals were HIV infection, organ transplantation, or other malignancies before inclusion. The key endpoint was the incidence of SPMs assessed in all study participants. The effect of treatment on SPMs was also investigated in patients who were followed up from first lymphoma diagnosis, with high-dose chemotherapy and autologous HSCT as a time-dependent exposure. FINDINGS: Of 910 patients with lymphoma assessed, 803 were included (537 [67%] were male and 266 [33%] were female); 4015 matched control individuals were included (2685 [67%] were male and 1330 [33%] were female). Ethnicity data were not available. Median follow-up was 7·76 years (IQR 4·77-11·73). The SPM rate was higher among patients receiving high-dose chemotherapy and autologous HSCT than matched control individuals (adjusted hazard ratio [HR] 2·35, 95% CI 1·93-2·87, p<0·0001). Patients receiving high-dose chemotherapy and autologous HSCT had a higher rate of non-melanoma skin cancer (2·94, 2·10-4·11, p<0·0001) and of myelodysplastic syndrome or acute myeloid leukaemia (AML; 41·13, 15·77-107·30, p<0·0001) than matched control individuals, but there was no significant difference in the rate of solid tumours (1·21, 0·89-1·64, p=0·24). The cumulative risk of SPMs at 10 years was 20% (95% CI 17-23) in patients compared with 14% (13-15) in matched control individuals. High-dose chemotherapy and autologous HSCT was associated with an increased risk of SPMs when analysed as a time-dependent exposure from first lymphoma diagnosis (adjusted HR 1·58, 95% CI 1·14-2·17, p=0·0054). INTERPRETATION: High-dose chemotherapy and autologous HSCT was associated with an increased risk of non-melanoma skin cancer and myelodysplastic syndrome or AML but not with increased risk of solid tumours in patients treated for lymphoma. These findings are relevant for future individualised risk-benefit assessments when choosing between high-dose chemotherapy and autologous HSCT and chimeric antigen receptor T-cell therapy in this setting.

RESUMEN
The aim of the study was to investigate the expression of angio- and lymphangiogenic molecules (vascular endothelial growth factors VEGF and VEGF-C and their receptors Flt-1, KDR, and Flt-4) in non-Hodgkin lymphomas (NHL) treated in the pre-rituximab era. Pre-therapeutic lymph-node biopsies from 155 patients with NHL (64 follicular lymphomas (FLs), 47 de novo diffuse large B-cell lymphomas (DLBCL) and 44 peripheral T-cell lymphomas (PTCL)) were stained by in situ hybridization and immunohistochemistry. Tumor cell expression of VEGF, VEGF-C and their receptors was detected in most of the analyzed biopsies. In FL, diffuse intratumoral VEGF staining correlated with shorter overall survival (OS) (p = 0.008) and diffuse KDR staining was associated with a higher risk of histologic transformation (p = 0.05). In DLBCL, high KDR expression predicted poor treatment response (p = 0.03) and had a significant adverse impact on OS (p < 0.001). In PTCL, diffuse tissue distribution of VEGF mRNA correlated with an unfavorable 5-year OS (p = 0.004).
