- This study estimated the risk of second primary malignancies after Hodgkin's lymphoma (HL) in relation to family history of cancer, age at diagnosis and latency, among 6946 patients treated for HL in Sweden in 1965–1995 identified through the Swedish Cancer Register (SCR). First-degree relatives (FDRs) to the HL patients and their malignancies were then ascertained together with their malignancies through the Multi-Generation Registry and SCR. The HL patient cohort was stratified on the number of FDRs with cancer, and standardised incidence ratios (SIRs) of developing SM were analysed. In the HL cohort, 781 SM were observed 1 year or longer after HL diagnosis. The risk for developing SM increased with the number of FDRs with cancer, SIRs being 2.26, 3.01, and 3.45 with 0, 1, or ≥2 FDRs with cancer, respectively. Hodgkin's lymphoma long-term survivors treated at a young age with a family history of cancer carry an increased risk for developing SM and may represent a subgroup where standardised screening for the most common cancer sites could be offered in a stringent surveillance programme.

- Background: Hodgkin lymphoma (HL) patients have a good prognosis after adequate treatment. Previous treatment with mantle field irradiation has been accompanied by an increased long-term risk of cardiovascular disease (CVD). This study identified co-morbidity factors for the development of cardiovascular side effects and initiated an intervention study aimed to decrease morbidity and mortality of CVD in HL survivors.Design: Hodgkin lymphoma patients aged ≤45 years diagnosed between 1965 and 1995 were invited to participate. In total, 453 patients completed a questionnaire that addressed co-morbidity factors and clinical symptoms. Of these, 319 accepted to participate in a structured clinical visit. The statistical analyses compared individuals with CVD with those with no CVD.Results: Cardiovascular disease was reported by 27.9%. Radiotherapy (odds ratio [OR]: 3.27), hypertension and hypercholesterolemia were shown to be independent risk factors for the development of CVD. The OR for CVD and valve disease in patients who received radiotherapy towards mediastinum was 4.48 and 6.07, respectively. At clinical visits, 42% of the patients were referred for further investigation and 24% of these had a cardiac ultrasound performed due to previously unknown heart murmurs.Conclusion: Radiotherapy towards mediastinum was an independent risk factor for CVD as well as hypercholesterolemia and hypertension. A reasonable approach as intervention for this cohort of patients is regular monitoring of hypertension and hypercholesterolemia and referral to adequate investigation when cardiac symptoms appear. Broad knowledge about the side effects from radiotherapy in the medical community and well-structured information regarding late side effects to the patients are all reasonable approaches as late effects can occur even 40 years after cancer treatment.

- Previous studies have shown increased cardiovascular mortality as late side effects in Hodgkin lymphoma (HL) patients. This study identifies stratifying risk factors for surveillance and defines concepts for a clinical feasible and noninvasive prospective protocol for intervention of cardiovascular side effects. HL patients diagnosed between 1965 and 1995 (n = 6.946) and their first-degree relatives (FDR) were identified through the Swedish Cancer Registry and the Swedish Multigeneration Registry. For the HL and FDR cohort, in-patient care for cardiovascular disease (CVD) was registered through the Hospital Discharge Registry, Sweden. Standard incidence ratios of developing CVD for the HL cohort were calculated. A markedly increased risk for in-patient care of CVD was observed in HL patients with HL diagnosed at age 40 years or younger and with more than 10 years follow-up. In the HL survivors, a family history of congestive heart failure (CHF) and coronary artery disease (CAD) increased the risk for these diseases. The Swedish Hodgkin Intervention and Prevention study started in 2007. In the pilot feasibility study for prospective intervention (47 patients), about 25% of the cases had side effects and laboratory abnormalities. These patients were referred to a cardiologist or general practitioner. In the prospective cohort, a positive family history for CHF or CAD could be a stratifying risk factor when setting up a surveillance model. The prospective on-going study presents an intervention model that screens and treats for comorbidity factors. This article also presents an overview of the study concept.

- Background: One-quarter of all cancer deaths in Sweden occur in hospitals. If the place of death affects the quality of end-of-life (EOL) is largely unknown.Methods: This population-based, retrospective study included all adults cancer deaths reported to the Swedish Register of Palliative Care in 2011-2013 (N = 41,729). Hospital deaths were compared to deaths occurring in general or specialised palliative care, or in nursing homes with respect to care quality indicators in the last week of life. Odds ratios (OR) with 95% confidence intervals (CI) were calculated with specialised palliative home care as reference.Results: Preferred place of death was unknown for 63% of hospitalised patients and consistent with the actual place of death in 25% compared to 97% in palliative home care. Hospitalised patients were less likely to be informed when death was imminent (OR: 0.3; CI: 0.28-0.33) as were their families (OR: 0.51; CI: 0.46-0.57). Validated screening tools were less often used in hospitals for assessment of pain (OR: 0.32; CI: 0.30-0.34) or other symptoms (OR: 0.31; CI: 0.28-0.34) despite similar levels of EOL symptoms. Prescriptions of as needed drugs against anxiety (OR: 0.27; CI: 0.24-0.30), nausea (OR: 0.19; CI: 0.17-0.21), or pulmonary secretions (OR: 0.29; CI: 0.26-0.32) were less prevalent in hospitals. Bereavement support was offered after 57% of hospital deaths compared to 87-97% in palliative care units and 72% in nursing homes.Conclusions: Dying in hospital was associated with inferior end-of-life care quality among cancer patients in Sweden.

Tidskriftsartikel (refereegranskat)abstract
- Background: Leucine-rich repeats and immunoglobulin-like domains 1 (LRIG1) copy number alterations and unbalanced gene recombination events have been reported to occur in breast cancer. Importantly, LRIG1 loss was recently shown to predict early and late relapse in stage I-II breast cancer.Methods: We developed droplet digital PCR (ddPCR) assays for the determination of relative LRIG1 copy numbers and used these assays to analyze LRIG1 in twelve healthy individuals, 34 breast tumor samples previously analyzed by fluorescence in situ hybridization (FISH), and 423 breast tumor cytosols.Results: Four of the LRIG1/reference gene assays were found to be precise and robust, showing copy number ratios close to 1 (mean, 0.984; standard deviation, +/-0.031) among the healthy control population. The correlation between the ddPCR assays and previous FISH results was low, possibly because of the different normalization strategies used. One in 34 breast tumors (2.9%) showed an unbalanced LRIG1 recombination event. LRIG1 copy number ratios were associated with the breast cancer subtype, steroid receptor status, ERBB2 status, tumor grade, and nodal status. Both LRIG1 loss and gain were associated with unfavorable metastasis-free survival; however, they did not remain significant prognostic factors after adjustment for common risk factors in the Cox regression analysis. Furthermore, LRIG1 loss was not significantly associated with survival in stage I and II cases.Conclusions: Although LRIG1 gene aberrations may be important determinants of breast cancer biology, and prognostic markers, the results of this study do not verify an important role for LRIG1 copy number analyses in predicting the risk of relapse in early-stage breast cancer.

- Background: If patient age affects the quality of end-of-life care in cancer is unknown. Using data from a population-based register of palliative care in Sweden, we addressed this question. Methods: This nation-wide study focused on the last week of life of adults dying from cancer in 2011-2012, based on data reported to a national quality register for end-of-life care (N = 26,976). We specifically investigated if age-dependent differences were present with respect to thirteen indicators of palliative care quality. Patients were categorised in one out of five pre-defined age groups. Odds ratios (OR) with 95% confidence intervals (CIs), adjusted for type of end-of-life care unit, were calculated using logistic regression, with the oldest group as reference. Findings: Age-dependent differences in implementation rate were detected for ten out of thirteen end-of-life care quality indicators, most of which were progressively less well met with each increment in age group. Compared to elderly cancer patients, young patients were more often informed about imminent death, (OR, 3.9; 95% CI 2.5-5.9, p < 0.001), were more often systematically assessed for the presence and severity of pain (OR, 1.6; 95% CI 1.2-2.1, p < 0.001) or other symptoms (OR, 1.4; 95% CI 1.0-1.9, p = 0.044), were more likely to be assessed by palliative care consultation services (OR, 4.3; 95% CI 3.3-5.7, p < 0.001) and to have injections prescribed as needed against pain (OR, 3.4; 95% CI 1.3-9.4, p = 0.016), anxiety (OR, 3.8; 95% CI 2.0-7.1, p < 0.001) or nausea (OR, 3.6; 95% CI 2.3-5.7, p < 0.001). The families of young patients were more likely to be informed about imminent death ( OR, 2.6; 95% CI 1.5-4.3, p = 0.001) and to be offered bereavement support ( OR, 4.6; 95% CI 2.7-7.8, p < 0.001). Interpretation: Old age is a risk indicator for poor end-of-life care quality among cancer patients in Sweden. Funding: The executive committee of the National Quality Registries in Sweden.

- Cryoprevention (CP) using ice (IC) is an effective strategy to prevent chemotherapy-induced oral mucositis (OM). However, the use of IC may cause adverse reactions and requires water of safe quality to minimize risk of serious infections. This randomized, blinded, parallel group, phase 3 trial was conducted in five Scandinavian centers. Eligible patients were diagnosed with multiple myeloma or lymphoma, scheduled to receive conditioning with high-dose chemotherapy prior to autologous hematopoietic stem cell transplantation (ASCT). Patients were assigned to cooling with IC or a novel intraoral cooling device (ICD). The primary outcome was the highest OM score during the study period, expressed as peak value on the Oral Mucositis Assessment Scale (OMAS-total). When the entire study population (n = 172) was analyzed for peak OMAS-total, the two cooling methods were equally effective. However, when the lymphoma group was analyzed separately, the ICD significantly reduced the peak OMAS-total score to a greater extent compared to IC (x +/- SD; 1.77 +/- 1.59 vs. 3.08 +/- 1.50; p = 0.047). Combined with existing evidence, the results of the present trial confirm that CP is an effective method to prevent OM. ClinicalTrials.gov. NCT03203733.
