- The aim of this study was to evaluate treatment results for Hodgkin lymphoma (HL) patients younger than 60 yr in stage IIB, treated according to the Swedish National Care Programme. The intention was also to identify specific subgroups depending on the number of negative prognostic factors the patients have, in order to optimise and differentiate future treatment. In total, 99 patients with HL stage IIB, diagnosed between 1985 and 1994, have been analysed. There were 47 men and 52 women and the median age was 33 yr (range 17-59). Eighty-six patients presented with supradiaphragmatic disease and 13 with infradiaphragmatic. The HL specific and overall 10-yr survival was 73 and 65%, respectively. The HL-specific survival for patients in pathological stage IIB tended to be better, although not statistically significant than for clinical stage IIB, despite less chemotherapy (P = 0.1). The patients in stage IIB who were selected for laparotomy were, however, younger and with fewer negative prognostic factors. The only significant negative prognostic factor was bulky disease (P = 0.001). The following factors also tended to have a negative influence on the prognosis although not statistically significant: the International Prognostic Score, the number of involved lymph node stations, extranodal involvement and leucocyte count > 15 x 10(9)/L. In conclusion, we suggest that bulky disease should be taken into account when treating patients with stage IIB HL.

- PURPOSE Balancing disease control and toxicity from chemotherapy and radiotherapy (RT) when treating early-stage classical Hodgkin lymphoma (cHL) is important. Available data on long-term toxicity after RT for cHL mostly refer to RT techniques no longer in use. We aimed to describe long-term toxicity from modern limited-field (LF)-RT after two or four cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD). PATIENTS AND METHODS This study included all patients with cHL treated with two or four cycles of ABVD and 30 Gy LF-RT during 1999-2005 in Sweden. Patients (n = 215) and comparators (n = 860), matched for age, gender, and region of residence, were cross-checked against national health registries for malignancies, diseases of the circulatory system (DCS), and diseases of the respiratory system (DRS) from the day of diagnosis of cHL. RESULTS The risk of a malignancy was higher for patients than comparators, hazard ratio (HR) 1.5 (95% CI, 1.0 to 2.4), as was the risk for DCS 1.5 (95% CI, 1.1 to 2.0) and for DRS 2.6 (95% CI, 1.6 to 4.3). The median followup was 16 years (range, 12-19 years). Of individual diagnoses in DCS, only venous thromboembolism was statistically significantly elevated. If the first 6 months (ie, time of active treatment for cHL) were excluded and censoring at relapse of cHL or diagnosis of any malignancy, the increased HR for venous thromboembolism diminished. Most of the excess risk for DRS consisted of asthma, HR 3.5 (95% CI, 1.8 to 6.8). Patients diagnosed with DRS were significantly younger than comparators. CONCLUSION Compared with toxicity from earlier RT techniques, excess morbidity was not eliminated, but lower than previously reported. The elevated risk of DRS was driven by diagnosis of asthma, which could in part be explained by misdiagnosis of persisting pulmonary toxicity.

- When treating limited stage classical Hodgkin lymphoma (cHL), balancing treatment efficacy and toxicity is important. Toxicities after extended-field radiotherapy are well documented. Investigators have aimed at reducing toxicity without compromising efficacy, mainly by using combined modality treatment (CMT), i.e. chemotherapy and limited-field radiotherapy. In some clinical trials, radiotherapy has been omitted. We evaluated 364 patients with stage I-IIA cHL treated between 1999 and 2005. Patients were treated with two or four cycles of doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) according to presence of risk factors, followed by 30 Gy limited-field (reduced compared to involved-field) radiotherapy. After a median follow-up of 16 years for survival, freedom from progression at five and ten years was 93% and overall survival at 5 and 10 years was 98% and 96%, respectively. Only two relapses, out of 27, occurred after more than 5 years. There was no excess mortality compared to the general population. Of the analysed subgroups, only patients with progression within five years showed significant excess mortality. The absence of excess mortality questions the concept of omitting radiotherapy after short-term chemotherapy, a strategy that has been associated with an elevated risk of relapse but not yet with a proven reduced long-term excess mortality.

- Hodgkin's lymphoma (HL) is characterized by a few Hodgkin, Reed-Sternberg cells (HRS) surrounded by benign cells. We recently reported that mast cells were the predominant CD30L-positive cells in HL tumours, and that they activate HRS in vitro through CD30L-CD30 interaction. Here, we investigated the clinical importance of mast cell infiltration in the tumours of 123 patients. Tumour specimens were stained with a mast-cell-specific antibody that detects tryptase. Mast cells were detected in virtually every case and increasing numbers of mast cells correlated to nodular sclerosis histology (P = 0.008). Patients with higher mast cell infiltration had a worse relapse-free survival (P = 0.01).

- The innate immune system is our first line of defense against danger signals but in Hodgkin's lymphoma the role seems opposite, favoring malignant development. In this article we describe interactions between Hodgkin's and Reed-Sternberg cells and the cells of the innate immune system: eosinophils, mast cells, neutrophils, and macrophages. These cells clearly contribute to the pathogenesis of this disease and to the prognosis. Cytokines and chemokines released from the activated immune cells probably promote tumor cell growth and survival along with angiogenesis. Mast cells and eosinophils seem also to contribute to the fibrosis that is so characteristic for nodular sclerosis.

- Background: Hodgkin lymphoma (HL) treatment protocols for children, adolescents and young adults traditionally differ, but the biological and clinical justification for this remains uncertain.Material and methods: We compared age-dependent clinical presentation and treatment and outcome for 1072 classical HL patients 0–24 years diagnosed in Denmark (1990–2010) and Sweden (1992–2009) in pediatric (n = 315, Denmark <15 years, Sweden <18 years) or adult departments (n = 757). Distribution of clinical characteristics was assessed with Pearson’s chi2-test and Mantel–Haenszel trend test. The Kaplan–Meier method was used for survival analyses. Hazard ratios (HR) were used to compare the different treatment groups and calculated using Cox regression.Results: Children (0–9 years) less often presented with advanced disease than adolescents (10–17 years) and young adults (18–24 years) (stage IIB-IV: children 32% vs. adolescents 50%, and adults 55%; p < .005). No variation in overall survival (OS) was seen between pediatric and adult departments or by country. Danish pediatric patients received radiotherapy (36%) less frequently than Swedish pediatric patients (71%) (p < .0001). Ten-year event-free survival (EFS) was lower among Danish pediatric patients (0–14 years) (0.79; 95% confidence interval (CI) 0.70–0.86) than among Swedish pediatric patients (0–17 years) (0.88; 95% CI 0.83–0.92), HR (1.93; 95% CI 1.08–3.46). A similar pattern was seen between adult patients in the two countries: Denmark 10-year EFS 0.85 (95% CI 0.81–0.88), Sweden 0.88 (95% CI 0.84–0.91), adjusted HR 1.51 (95% CI 1.03–2.22).Conclusion: Adolescents and young adults shared similar clinical presentation suggesting a rationale of harmonized treatment for these groups. Both adult and pediatric protocols provided high OS with no significant difference between the departments. The less frequent use of radiotherapy in Danish pediatric patients corresponded to a lower EFS, but comparable OS in all groups confirmed effective rescue strategies for the relapsing patients.

- OBJECTIVES: To study Hodgkin lymphoma (HL) microenvironment in a Swedish paediatric population and its relation to clinical parameters.METHODS: Tumour tissue from classical HL (cHL) (n=87) and nodular lymphocyte predominant HL (NLPHL) (n=11) was investigated for Epstein-Barr Virus (EBV) and analysed for eosinophils, mast cells and macrophages.RESULTS: In cHL, EBV positivity was more common in low age (p<0.001) and in mixed cellularity (MC) (p<0.001). Higher mast cell infiltration was seen in stage III-IV (p<0.001), and with presence of B-symptoms (p=0.01). Cases with high mast cell counts displayed higher erythrocyte sedimentation rate (ESR), lower haemoglobin and albumin levels. Higher macrophage infiltration was seen in stage III-IV (p=0.02) and there was elevated ESR and neutrophil count. All NLPHL cases were EBV negative, had lower rates of inflammatory cells and lower degree of inflammatory reaction in laboratory parameters. There was no difference in survival estimates with regard to infiltration of inflammatory cells.CONCLUSIONS: Higher levels of mast cells and macrophages in cHL tumours reflected the clinical presentation in laboratory parameters, B-symptoms and more advanced stages. NLPHL differs from cHL in numbers of inflammatory cells in the tumour, and in laboratory parameters. This article is protected by copyright. All rights reserved.

- Childbirth rates in classical Hodgkin lymphoma (cHL) survivors have historically been reduced compared to the general population. Understanding if contemporary treatment protocols are associated with reduced fertility is crucial as treatment guidelines shift toward more liberal use of intensive chemotherapy. We identified 2834 individuals aged 18-40 years with cHL in Swedish and Danish lymphoma registers, and in the clinical database at Oslo University Hospital diagnosed 1995-2018, who were linked to national medical birth registers. Cox regression adjusted for stage, performance status, year, and age at diagnosis was used to estimate hazard ratios (HRs) and 95% confidence intervals (CI) contrasting time to first childbirth by treatment groups (ABVD, 2-4 BEACOPP, 6-8 BEACOPP) up to 10 years after diagnosis. Overall, 74.8% of patients were treated with ABVD, 3.1% with 2-4 BEACOPP and 11.2% with 6-8 BEACOPP. Adjusted HRs comparing childbirth rates in individuals treated with 6-8 BEACOPP, and 2-4 BEACOPP to ABVD were 0.53 (CI: 0.36-0.77) and 0.33 (CI: 0.12-0.91) for males, and 0.91 (CI: 0.61-1.34) and 0.38 (CI: 0.12-1.21) for females. Cumulative incidence of childbirths after 10 years was 19.8% (CI: 14.5%-27.0%) for males and 34.3% (CI: 25.8%-45.6%) for females treated with 6-8 BEACOPP. Proportions of children born after assisted reproductive technique (ART) treatments were 77.4% (CI: 60.2-88.6%) for males following 6-8 BEACOPP, and <11% for females. Among ABVD treated patients the corresponding proportions were 12.2% (CI: 8.5%-17.3%) and 10.6% (CI: 7.4%-14.9%). BEACOPP treatment is associated with decreased childbirth rates compared to ABVD in male, but not female, cHL patients, despite widespread access to ART in the Nordics.
