Outcome data of patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) beyond the second line are scarce outside of clinical trials. Novel therapies in the R/R setting have been approved based on single-arm trials, but results need to be contextualized by real-world outcomes. Medical records from 3753 Danish adults diagnosed with DLBCL were reviewed. Patients previously treated with rituximab and anthracycline-based chemotherapy who received the third or later line (3 L+) of treatment after 1 January 2015, were included. Only 189 patients with a median age of 71 years were eligible. The median time since the last line of therapy was 6 months. Patients were treated with either best supportive care (22%), platinum-based salvage therapy (13%), low-intensity chemotherapy (22%), in clinical trial (14%) or various combination treatments (32%). The 2-year OS-/PFS estimates were 25% and 12% for all patients and 49% and 17% for those treated with platinum-based salvage therapy. Age ≥70, CNS involvement, elevated LDH and ECOG ≥2 predicted poor outcomes, and patients with 0–1 of these risk factors had a 2-year OS estimate of 65%. Only a very small fraction of DLBCL patients received third-line treatment and were eligible for inclusion. Outcomes were generally poor, but better in intensively treated, fit young patients with limited disease., Outcome data of patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) beyond the second line are scarce outside of clinical trials.

Objectives: Extraosseous plasmacytoma (EOP) is a rare plasma cell neoplasm that tends to convert to plasma cell myeloma (PCM) in about 11% to 35% of cases. It has a predilection for the upper respiratory tract, prototypically affecting the nasal cavity and paranasal sinuses. Contemporary first-line treatment is radiotherapy, with more recent studies showing an added benefit of combining radiation with surgery. In this cohort study, we aimed to examine clinical presentation, treatment, and prognosis for all patients nationwide from 1980 through 2017. Furthermore, we determined the size and extension of tumors, investigating the rate at which minimally invasive surgery would have been possible. Methods: Patients were found in the national pathology registry, and all biopsies were collected for pathology review by a hematopathologist. We performed survival statistics for overall survival (OS), progression-free survival (PFS), and the cumulative incidence of conversion to PCM. Results: Twenty-three patients were included. The median age was 65, and patients were primarily men (78%). Tumors were located in either the nasal cavity (57%), maxillary sinus (39%), or sphenoid sinus (4%). In most cases, the tumor was <5 cm (65%) without extension to adjacent structures (60%). The national incidence was 0.02/100,000 person-years, the median symptom duration until diagnosis was 5 months, and none of the patients presented with contiguous spread to regional lymph nodes. Stand-alone radiotherapy was the predominant treatment (61%). In the entire cohort, one patient died from the initial disease, and six patients died from either relapse of EOP or PCM. The 5-year OS, PFS, and conversion rate to PCM were 78%, 56%, and 23%, respectively. Conclusion: SN-EOP responds well to radiotherapy, but relapse and conversion to PCM were not uncommon and entailed a poor prognosis. Most tumors were endoscopically resectable and non-invasive, making the majority of tumors suitable for surgery

Compared to Asian and Latin American populations, sinonasal NK- or T-cell lymphoma is rare in Europe. All patients with sinonasal NK- or T-cell lymphoma in Denmark from 1980 to 2017 were validated histologically, and the disease behavior and demographics were extracted from medical records and national registries. Prognostic factors associated with mortality were determined using survival statistics. We included 56 patients: 40 extranodal NK/T-cell lymphoma (nasal type) (ENKTCL) and 16 peripheral T-cell lymphoma (not otherwise specified) (PTCL). The median age was 66, and most patients were male (72%). The ENKTCL and PTCL 5-year overall survival was 48% and 50%, respectively; progression-free survival was 38% for both. With ENKTCL, stage and performance status increased mortality significantly (HR = 8.6; p < 0.001 and HR = 4.23; p = 0.04). In conclusion, disseminated disease had a dismal outcome and the onset of ENKTCL in this ethnically homogeneous European cohort was about a decade later than reported in Asian populations.

Lymphomas of the nasal cavity and paranasal sinuses (NPS) are rare. Knowledge on sinonasal B-cell lymphoma (SNBCL) primarily comes from case series or single-center studies on small cohorts. We sought to determine the subtype distribution, clinical characteristics, disease behavior, and prognosis on a nationwide scale, with an emphasis on prognostic factors for the most common sinonasal lymphoma, primary sinonasal diffuse large B-cell lymphoma (PSDLBCL). We collated all data from medical records and national databases on patients registered with SNBCL from 1980 through 2018 in the national pathology registry and collected all tissue samples for validation of diagnosis. We included 205 patients and found 10 different subtypes of lymphoma. Diffuse large B-cell lymphoma (DLBCL) was the predominant subtype (80%). The incidence of SNBCL was 0.14/100,000 person-years. The five-year progression-free survival (PFS) and overall survival rates for PSDLBCL were 50% and 56%, respectively. For PSDLBCL, Rituximab showed a statistically significant effect (Hazard Ratio 0.22, p < 0.001), whereas consolidative radiotherapy combined with immunochemotherapy was of limited value (PFS, p = 0.93). When treatment failure occurred, DLBCL showed a distinct pattern of recurrence/dissemination to the NPS, skin, breast, central nervous system (CNS), and/or testis. Collectively, DLBCL comprised a clear majority of SNBCLs, although nine other subtypes were represented. Data showed that immunochemotherapy increased survival for PSDLBCL and that the addition of radiotherapy did not benefit patients. Furthermore, treatment failure for sinonasal DLBCL showed a possible common pathogenesis with primary extranodal lymphomas of specific locations (e.g., CNS, skin, breast, and testis).

Udgivelsesdato: 2009-Oct, BACKGROUND: Options for the prevention of cardiovascular disease, the greatest global cause of death, include population preventive measures (the Rose approach), or specifically seeking out and managing high-risk cases. However, the likely benefit of a population approach has been recently questioned. OBJECTIVE: To compare the estimated effects of population strategies at varying levels of population-wide risk factor reduction and high-risk strategies at varying rates of screening uptake on cardiovascular disease mortality. METHODS: Data (of 109 954 participants) were pooled from six European general population cohort studies [the high-risk cohorts from the SCORE (Systematic COronary Risk Evaluation) dataset]. The effects of various population and high-risk strategies for the reduction of risk factors were estimated by calculating the change in 10-year risk of cardiovascular disease mortality (SCORE risk) before and after the particular intervention. Risk factors studied were: total cholesterol, blood pressure and smoking. RESULTS: At population level, if a 10-year reduction of blood cholesterol level of 10%, a BP reduction of 10% and a 10% reduction in the prevalence of smoking is considered possible, then 9125 lives per million of the population would be saved over 10 years. In contrast, an approach that treats all high-risk individuals with a polypill containing statin, three half-dose antihypertensives and aspirin, with a 20-80% uptake, would save 1861-7452 lives per million. However, the high-risk estimates are very optimistic, as their achievement would require complete compliance. CONCLUSION: High-risk and population strategies are complementary. These estimates of the benefits of each may be useful to health planners, when combined with their local knowledge. Recently, benefits of population strategies have been underestimated.

Udgivelsesdato: 2009-Mar, OBJECTIVE: To analyze mental distress in relation to participation in lifestyle intervention. METHODS: In 2000-2001 a total of 1948 consecutive participants, living in the suburbs of Copenhagen, were asked to complete a short version of SCL-90-R (anxiety, depression, and somatization) before screening, immediately after screening, and one and 10 months after screening. The screening classified participants into high or low risk individuals. High risk individuals received personal lifestyle counselling and were randomized to either group-based counselling (A) or referred care (B). Multilevel regression models taking into account repeated measurements and missing data at follow-up were performed. RESULTS: Before screening, high risk individuals had higher scores on anxiety, depression, and somatization than low risk individuals. All categories of participants decreased in scores after screening. The scores increased after 1 month, but were still significantly lower than before screening. After 10 months, low risk individuals and high risk individuals in group A still had significantly lower scores (except for depression) compared with pre-screening levels, whereas high risk individuals in group B reached the pre-screening level (except for anxiety). CONCLUSION: Screening for risk of cardiovascular disease followed by health counselling does not give rise to mental distress, but has a temporary beneficial effect.

Udgivelsesdato: 2003-May, Elevation in plasma total homocysteine (tHcy) is believed to be causally related to cardiovascular disease. Like age and sex, the thermolabile variant of methylenetetrahydrofolate reductase (MTHFR(C677T)) is an important nonmodifiable determinant of tHcy, which may be considered when describing normal ranges of tHcy in the general population. We investigated the simultaneous effect of sex, age, and MTHFR(C677T) genotype on the distribution of tHcy in a cross-sectional study design. THcy concentrations and MTHFR(C677T) genotype were determined in a population-based sample of 2,788 Danish men and women aged 30-60 years participating in the Inter99 Study. The prevalences of MTHFR(C677T) genotypes were 48.8% (CC), 42.4% (CT), and 8.8% (TT). The overall median tHcy was 8.1 micromol/l, and the 2.5-97.5 percentiles were 4.8-17.8 micro mol/l. The estimated proportionally higher level of tHcy in men compared to women was 14.3% (P<0.001). A significant interaction term was found between age and MTHFR(C677T) genotype (P<0.001). The estimated changes in tHcy per 5 years of age were 1.5% in CC individuals (P<0.01), 2.1% in CT individuals (P<0.001), and -4.1% in TT individuals (P<0.01). The T allele was associated with elevated tHcy. However, the proportionally higher level of tHcy in TT individuals compared to CT and CC individuals decreased with increasing age. The MTHFR(C677T) polymorphism explained 6% of the phenotypic variation in tHcy. In conclusion, we found that tHcy is associated with sex, age, and MTHFR genotype. Our results indicate that the effect of age is modified by MTHFR genotype.
