RESUMEN
BACKGROUND: A new primary cancer is a serious late effect of a pre-existing cancer diagnosis, and can be attributed to hereditary cancer syndromes, immune or hormonal factors, cancer treatment, or modifiable lifestyle or environmental factors. We investigated the absolute and relative incidence of second primary cancers in a large cohort of Danish cancer survivors. Furthermore, we examined the association between alcohol-related, smoking-related, virus-related, and hormone-related first and second primary cancers. METHODS: In this retrospective cohort study, we identified a cohort of Danish adults (aged ≥40 years) diagnosed with cancer from Jan 1, 1997, to Dec 31, 2014 and alive 1 year after diagnosis. Follow-up was from date of first cancer diagnosis and lasted up to 24 years, ending on Dec 31, 2020. Cohort identification and information on second primary cancers was obtained from the Danish Cancer Registry, and comorbidity and sociodemographic information was obtained from Danish population-based registries. Overall, and for 27 cancer types, cumulative incidence functions and Cox proportional hazard regression models were used to estimate the incidence of second primary cancer and death, and hazard ratios (HRs) and 95% CIs of second primary cancer adjusted for sex, age and year of diagnosis, cohabitation status, income, and comorbidity. FINDINGS: 457 334 Danish adults were included in our study (230 150 [50·3%] male individuals and 227 184 [49·7%] female individuals; median age at diagnosis 68·3 years, IQR 59·7-76·6; median follow-up 3·6 years, IQR 0·6-9·3). The cumulative incidence of second primary cancer increased over time from 6·3% (95% CI 6·2-6·4) 5 years after diagnosis to 10·5% (10·4-10·6) 10 years after diagnosis and to 13·5% (13·4-13·7) 15 years after diagnosis. The highest cumulative incidence of second primary cancer 10 years after diagnosis was observed in survivors of cancers in the larynx (21·8%, 20·5-23·1), oropharynx and oral cavity (19·5%, 18·7-20·3), and bladder and urinary tract (18·5%, 18·0-19·0). Survivors of cancers related to alcohol (HR 1·09, 95% CI 1·06-1·13), smoking (1·73, 1·68-1·78), diet high in red or processed meat (1·32, 1·24-1·39), or virus (1·23, 1·13-1·35) were at increased risk of developing a second cancer with the same aetiology, whereas having had a hormone-related first cancer was associated with lower risk of a second hormone-related cancer (0·77, 0·73-0·81). INTERPRETATION: Our results could help optimise prevention efforts targeting modifiable risk factors to reduce risk of developing a second primary cancer.

OBJECTIVE: Patients with incurable cancer should receive general palliative care according to their needs, as provided through collaboration between hospital departments, municipalities, and general practices and as outlined in national guidelines. However, the implementation of general palliative care in Denmark has been inadequate. This study aimed to investigate the healthcare professionals' (HCPs') perceptions on barriers to and facilitators of the implementation of the Danish National Guideline (NG) for general palliative care. METHODS: This descriptive, qualitative study was guided by the Consolidated Framework for Implementation Research (CFIR). Qualitative focus group and individual interviews were conducted with 23 HCPs. The interview guide, coding, analysis, and reporting of findings were developed within the CFIR framework. RESULTS: The main barriers to implementing NG were as follows: lack of knowledge about the NG, lack of an implementation plan, and insufficient communication and collaboration across sectors. Important facilitators were as follows: HCP motivation to meet palliative care needs, HCPs with special functions taking responsibility for incorporating NG into local guidelines, and the role of district nurses specialised in palliative care as opinion leaders providing security and continuity for the HCPs working in palliative care. CONCLUSIONS: To address the needs of patients with incurable cancer, greater efforts are required on implementing general palliative care. Although HCPs in our setting were motivated to improve NG implementation, financial resources and strategies are necessary to ensure sufficient knowledge uptake and accommodate identified barriers in order to translate the NG into practice.

Difficulties in recruiting newly bereaved families and following them over time present a major barrier in grief research following the death of a spouse/parent. We established FALCON-the first prospective nationwide cohort of families with children below age 18 years whose parent died in Denmark between April 2019 and July 2021. Data from parents and children were collected within 2 months of death with ongoing follow-up assessments up to 18 months post-death. A total of 992 families were invited. The final cohort consisted of 250 families (250 widowed parents, 134 adolescents, 120 children aged 6-12 years and 63 children aged 0-5 years). In this paper, we describe the rationale for the cohort's creation, the challenges of researching grief in families, the methods used and future plans to utilize this unique family-level dataset.

Knowledge about effective coping strategies is important to support bereaved adolescents who have lost a parent. We used data on 104 bereaved adolescents (13-17 years) from the FALCON nationwide questionnaire study of parentally bereaved families. We examined associations between adolescents' control-oriented and escape-oriented coping strategies (KidCOPE scale) approximately two months after loss and grief symptoms (PG-13 scale) at six months follow-up. We also examined associations between the perceived efficacy of each coping strategy at baseline and grief symptoms at six months. The use of escape-oriented coping (e.g., distraction, self-criticism and social withdrawal) was associated with higher grief symptoms at six months follow-up (ß = 0.4, 95% CI 0.1-0.9, p = 0.02), but no associations were found for control-oriented coping or perceived coping efficacy. Finding alternatives to the use of escape-oriented coping strategies may be an important part of grief interventions for bereaved adolescents.
RESUMEN
BACKGROUND: Prehabilitation with exercise interventions during neoadjuvant chemotherapy (NACT) is effective in reducing physical and psychosocial chemotherapy-related adverse events in patients with cancer. In preclinical studies, data also support a growth inhibitory effect of aerobic exercise on the tumour microenvironment with possible improved chemotherapy delivery but evidence in human patients is limited. The aim of the study here described is to investigate if supervised exercise with high-intensity aerobic and resistance training during NACT can improve tumour reduction in patients with breast cancer. METHODS: This parallel two-armed randomized controlled trial is planned to include 120 women aged ≥ 18 years with newly diagnosed breast cancer starting standard NACT at a university hospital in Denmark (a total of 90 participants needed according to the power calculation and allowing 25% (n = 30) dropout). The participants will be randomized to usual care or supervised exercise consisting of high-intensity interval training on a stationary exercise bike and machine-based progressive resistance training offered three times a week for 24 weeks during NACT, and screening-based advice to seek counselling in case of moderate-severe psychological distress (Neo-Train program). The primary outcome is tumour size change (maximum diameter of the largest lesion in millimetre) measured by magnetic resonance imaging prior to surgery. Secondary outcomes include clinical/pathological, physical and patient-reported measures such as relative dose intensity of NACT, hospital admissions, body composition, physical fitness, muscle strength, health-related quality of life, general anxiety, depression, and biological measures such as intratumoural vascularity, tumour infiltrating lymphocytes, circulating tumour DNA and blood chemistry. Outcomes will be measured at baseline (one week before to 1-2 weeks after starting NACT), during NACT (approximately week 7, 13 and 19), pre-surgery (approximately week 21-29), at surgery (approximately week 21-30) and 3 months post-surgery (approximately 33-42 weeks from baseline). DISCUSSION: This study will provide novel and important data on the potential benefits of supervised aerobic and resistance exercise concomitant to NACT on tumour response and the tumour microenvironment in patients with breast cancer, with potential importance for survival and risk of recurrence. If effective, our study may help increase focus of exercise as an active part of the neoadjuvant treatment strategy. TRIAL REGISTRATION: The trial was registered at ClinicalTrials.gov (NCT04623554) on November 10, 2020.

BACKGROUND: Fatigue, insomnia and pain are some of the most common and distressing symptoms experienced during breast cancer (BC) treatment and survivorship. The symptoms have been found to impact one another and to form a symptom cluster, and greater severity of the symptoms may be negatively associated with physical and emotional functioning in survivorship. In exploratory analyses from a randomized controlled trial examining the effect of progressive resistance training on the development of lymphedema after BC, we aimed to examine the burden of the symptom cluster fatigue-pain-insomnia, and its prognostic value for long-term symptom severity as well as emotional and physical functioning. MATERIAL AND METHODS: Latent profile analysis was used to identify groups with similar severity of pain, fatigue and insomnia among 158 patients with BC two weeks after surgery. Mixed effects Tobit regression models were used to estimate fatigue, pain, insomnia, and physical and emotional functioning 20 weeks, 1 year and 3.5 years after surgery. RESULTS: Two symptom burden groups were identified: 80% of women had a low severity while 20% of women had a high severity of the three symptoms after BC surgery. 3.5 years later, the women with high symptom burden post-surgery still had higher pain, insomnia and fatigue scores than women with low symptom burden. High symptom burden post-surgery was associated with worse physical functioning 3.5 years later, while emotional functioning was only negatively impacted during the first year. DISCUSSION: These findings warrant larger studies investigating if symptom burden early in BC trajectory can be used for risk stratification for persistent symptoms and diminished physical functioning with the purpose of developing and implementing targeted interventions.

Background In Denmark, the Cancer Patient Pathway for Non-Specific Signs and Symptoms (NSSC-CPP) has been implemented with variations: in some areas, general practitioners (GPs) do the initial diagnostic work-up (GP paradigm); in other areas, patients are referred directly to the hospital (hospital paradigm). There is no evidence to suggest the most beneficial organisation. Therefore, this study aims to compare the occurrence of colon cancer and the risk of non-localised cancer stage between the GP and hospital paradigms.Material and Methods In this registry-based case-control study, we applied multivariable binary logistic regression models to estimate the odds ratios (OR) of colon cancer and non-localised stage associated with the GP paradigm and hospital paradigm. All cases and controls were assigned to a paradigm based on their diagnostic activity (CT scan or CPP) six months before the index date. As not all CT scans in the control group were part of the cancer work-up as a sensitivity analysis, we investigated the impact of varying the fraction of these, which were randomly removed using a bootstrap approach for inference.Results The GP paradigm was more likely to result in a cancer diagnosis than the hospital paradigm; ORs ranged from 1.91-3.15 considering different fractions of CT scans as part of cancer work-up. No difference was found in the cancer stage between the two paradigms; ORs ranged from 1.08-1.10 and were not statistically significant.Conclusion Patients in the GP paradigm were diagnosed with colon cancer more often, but we cannot conclude that the distribution of respectively localised or non-localised extent of disease is different from that of patients in the hospital paradigm.

BACKGROUND: The primary aim was to assess Health Related Quality of Life (HRQoL), anxiety and depression in patients and caregivers during follow-up care after curative treatment for cancer in the pancreas, duodenum, or bile ducts. The secondary aim was to assess dyadic coping and the burden of being a caregiver. MATERIALS AND METHODS: In this prospective observational cohort study, we included patients and caregivers at first follow-up visit to conduct the following: Demographic characteristics, The European Organization for Research and Treatment of Cancer Quality of Life, the pancreas and bile duct module, EQ5D 3L, GAD-7 and PHQ-9 at baseline, and at six and nine-months follow-up visit. Demographic characteristics, Dyadic Coping Inventory and Zarit Caregiver Burden Questionnaire were conducted at baseline and at nine-months of follow-up visit. RESULTS: The response rate was 42% with 104 of the 248 invited patients completing the questionnaires at baseline: 78 (75% of 104) after six and 69 (66% of 104) after nine months. The median (Q25,75) time for inclusion was 33.6 (13.4, 38) and 29.1 (18.3, 36) weeks after surgery for patients with pancreatic or duodenal cancer, and bile duct cancer, respectively. The response rate of caregivers was 88% with 75 of 85 completing the questionnaires. Fifty percent of patients with pancreatic or duodenal cancer had diarrhea at baseline. After six and nine months, this increased to 75%. Fatigue was the most prominent symptom in patients with bile duct cancer after nine months with 25% of patients scoring this as a clinical symptom. CONCLUSIONS: The study highlights the need to systematically screen physical and psychological symptoms in patients and caregivers during follow-up care after treatment for cancer in the pancreas, duodenum and bile ducts. Symptom management during follow-up care should be prioritized by clinicians.

BACKGROUND: Oncologist-led follow-up after breast cancer (BC) is increasingly replaced with less intensive follow-up based on higher self-management, which may overburden the less resourceful patients. We examined whether socioeconomic factors measured recently after the implementation of a new follow-up program for BC patients were associated with health-related quality of life (HRQoL) and self-management 12 months later. METHODOLOGY: Between January and August 2017, we invited 1773 patients in Region Zealand, Denmark, to participate in baseline and 12 months follow-up questionnaires. The patients had surgery for low- and intermediate risk BC 1-10 years prior to the survey, and they had recently been allocated to the new follow-up program of either patient-initiated follow-up, or in-person or telephone follow-up with a nurse, based on patients' preferences. We examined associations between socioeconomic factors (education and cohabitation) at baseline and two outcomes: HRQoL (EORTC QLQ-C30 and QLQ-BR23) and self-management factors (health care provider, confidence in follow-up, contact at symptoms of concern, and self-efficacy) at 12 months follow-up. Sensitivity analyses were performed according to time since diagnosis (≤ 5 > 5 years). Furthermore, we investigated whether treatment and self-management factors modified the associations. RESULTS: A total of 987 patients were included in the analyses. We found no statistically significant associations between socioeconomic factors and HRQoL, except in patients ≤ 5 years from diagnosis. For self-management patients with short education were more likely to report that they had not experience relevant symptoms of concern compared to those with medium/long education (OR 1.75 95% CI: 1.04; 2.95). We found no clear patterns indicating that treatment or self-management factors modified the associations between socioeconomics' and HRQoL. CONCLUSION: Overall socioeconomic factors did not influence HRQoL and self-management factors except for experiencing and reporting relevant symptoms of concern. Socioeconomic factors may, however, influence HRQoL in patients within five years of diagnosis.

BACKGROUND: The promise of prolonged survival after psychosocial interventions has long been studied, but not convincingly demonstrated. This study aims to investigate whether a psychosocial group intervention improved long-term survival in women with early-stage breast cancer and investigate differences in baseline characteristics and survival between study participants and non-participants. METHODS: A total of 201 patients were randomized to two six-hour psychoeducation sessions and eight weekly sessions of group psychotherapy or care as usual. Additionally, 151 eligible patients declined to participate. Eligible patients were diagnosed and treated at Herlev Hospital, Denmark, and followed for vital status up to 18 years after their primary surgical treatment. Cox's proportional hazard regressions were used to estimate hazard ratios (HRs) for survival. RESULTS: The intervention did not significantly improve survival in the intervention group compared with the control group (HR, 0.68; 95% confidence interval (CI), 0.41-1.14). Participants and non-participants differed significantly in age, cancer stage, adjuvant chemotherapy, and crude survival. When adjusted, no significant survival difference between participants and non-participants remained (HR, 0.77; 95% CI, 0.53-1.11). CONCLUSIONS: We could not show improved long-term survival after the psychosocial intervention. Participants survived longer than nonparticipants, but clinical and demographic characteristics, rather than study participation, seem accountable for this difference.

BACKGROUND: Prior studies of suicide risk among prostate cancer patients are conflicting. We compared the risk of suicide in prostate cancer patients to cancer-free men including adjustment for clinical stage, socioeconomic position, somatic comorbidity, and previous depression. MATERIALS AND METHODS: A cohort of 37,527 men diagnosed with prostate cancer in Denmark during 1998-2011 was identified in the Danish Prostate Cancer Registry (DaPCaR) and compared with 357,384 cancer-free men matched by age at the time of diagnosis. The primary outcome was death from suicide. Data were analyzed using cumulative incidence functions and multivariable Cox regression models. RESULTS: Among prostate cancer patients, 3813 had a previous depression, defined as filed antidepressant prescription within three years before diagnosis. In the study period, 108 prostate cancer patients were registered with suicide as the cause of death, hereof 26 with previous depression. There was no difference in the cumulative incidence of suicide between prostate cancer patients and cancer-free men. There was no effect modification of previous depression on the risk of suicide (p = .12). The hazard ratio (HR) for suicide varied with time since diagnosis. A sensitivity analysis showed that the risk of suicide was highest within the first year of diagnosis where prostate cancer patients had a 1.70-fold increased hazard compared with cancer-free men (95% CI, 1.11-2.59). Men with prostate cancer and previous depression had a three-fold increased hazard for suicide compared with prostate cancer patients without a history of depression (HR 2.84, 95% CI, 1.82-4.45). CONCLUSION: The absolute risk of suicide is low following a prostate cancer diagnosis. Time since diagnosis and a history of depression was associated with the highest risk of suicide. Healthcare professionals should be aware of an increased risk of suicide among men with previous depression, especially in the immediate aftermath of the diagnosis.

BACKGROUND: The risk of cardiovascular events in patients treated for colorectal cancer is debated due to diverging results in previous studies. Colorectal cancer and cardiovascular disease share several risk factors such as physical inactivity, obesity, and smoking. Information about confounding covariates and follow-up time are therefore essential to address the issue. This study aims to investigate the risk of new-onset cardiovascular events for patients with stage I-III colorectal cancer receiving elective surgery compared to a matched population. MATERIAL AND METHODS: Using a prospective cohort, we compared cardiovascular events among 876 patients treated with elective surgery for incident stage I-III colorectal cancer diagnosed between January 1st, 2001 and December 31st, 2016 to a cancer-free cohort matched by age, sex, and time since enrollment (N = 3504). Regression analyses were adjusted for lifestyle, cardiovascular risk factors, and comorbidity. Multivariable analyses were used to identify risk factors associated with cardiovascular events in the postoperative (<90 days of elective surgery) and long-term phase (>90 days after elective surgery). RESULTS: After a median follow-up of 3.9 years, the hazard ratio (HR) for incident heart failure was 1.53 (95% CI 1.02-2.28) among patients operated for colorectal cancer. The postoperative risk of myocardial infarction or angina pectoris was associated with the use of lipid-lowering drugs. Long-term risks of cardiovascular events were ASA-score of III+IV and lipid-lowering drugs with HRs ranging from 2.20 to 15.8. Further, the use of antihypertensive drugs was associated with an HR of 2.09 (95% CI 1.06-4.13) for angina pectoris or acute myocardial infarction. Heart failure was associated with being overweight, diabetes, and anastomosis leakage. CONCLUSION: We observed an increased hazard of heart failure in patients operated on for stage I-III colorectal cancer compared to cancer-free comparisons. We identified several potential risk factors for cardiovascular events within and beyond 90 days of elective surgery.

BACKGROUND: The socioeconomic differences in survival are pronounced for patients diagnosed with head and neck cancer; disease stage at diagnosis is suggested to be a main driver of this association. This nationwide, population-based study investigates socioeconomic differences in the pre-diagnostic interval and disease stage at diagnosis. MATERIAL AND METHODS: Information on patient-reported symptoms, symptom onset and disease-specific factors was obtained from the nationwide population-based Danish Head and Neck Cancer Group (DAHANCA) database for patients diagnosed with head and neck squamous cell carcinoma between 2008 and 2019 in Denmark. Socioeconomic position (SEP) was measured by individual-level education, income and cohabitation status obtained from administrative registers. Socioeconomic differences in the interval from symptom onset to diagnosis were investigated in general linear models with 95% confidence intervals (CIs); overall and by subsite, symptom and comorbidity score. Consultation patterns prior to diagnosis were examined using methods for change-point detection. Associations with advanced-stage disease were estimated in logistic regression models. RESULTS: Patients with low, medium and high SEP had a similar interval from patient-reported symptom onset to diagnosis of 10 weeks. Although this interval varied according to primary symptom and anatomical subsite, no apparent socioeconomic differences were observed within these subgroups. Aligned with the patient-reported symptom onset, a distinct increase in consultation rates was observed at 9 weeks (95% CI [7.3; 10.7]) for patients with low SEP and 7 weeks (95% CI [4.8; 9.2]) for patients with high SEP, with overlapping CIs. Patients with low compared to high SEP had increased odds for advanced-stage glottic and oral cavity squamous cell carcinoma. For the remaining subsites the association varied according to SEP-indicator and TNM-edition. CONCLUSION: The interval from symptom onset to diagnosis and consultation patterns were similar across SEP groups. Still, socioeconomic differences in stage at diagnosis were observed for some - but not all - subsites.

BACKGROUND: To identify non-small-cell lung cancer (NSCLC) patients in need of comprehensive support, we examined the association between patient and disease-related factors of vulnerability related to not receiving guideline-recommended treatment. MATERIAL AND METHODS: We identified 14,597 non-small-cell lung cancer (NSCLC) patients with performance status <3 during 2013-2018 in the Danish Lung Cancer Registry. Multivariate logistic regression models were used to estimate Odds Ratios (ORs) and 95% confidence intervals (CIs) for receiving guideline-recommended treatment according to stage, comorbidities, age, performance status, long distance to hospital, cohabitation status, education and alcohol abuse. RESULTS: 21% of stage I-IIIA NSCLC patients did not receive curative treatment while 10% with stage IIIB-IV did not receive any oncological therapy. Factors associated with reduced likelihood of receiving curative treatment included: advanced stage (OR = 0.45; 95% CI = 0.42-0.49), somatic comorbidity (OR = 0.72; 95% CI = 0.63-0.83), age ≥ 80 years (OR = 0.59; 95% CI = 0.55-0.64), performance status = 2 (OR = 0.33; 95% CI = 0.28-0.39) and living alone (OR = 0.79; 95% CI = 0.69-0.90). Results were similar for stage IIIB-IV NSCLC patients, although a statistically significant association was also seen for long distances to the hospital (OR = 0.71; 95% CI = 0.58-0.86). CONCLUSIONS: Several factors are associated with not receiving guideline-recommended NSCLC treatment with age, performance status, comorbidity and stage being most predictive of no treatment receipt. Efforts should be made to develop support for vulnerable lung cancer patients to improve adherence to optimal first-line therapy.

PURPOSE: Lymphedema (LE) is a common complication after breast cancer treatment, which negatively affects the quality of life (QOL). Hyperbaric Oxygen Treatment (HBOT) is an established treatment for radiation-induced tissue injury, but evidence of effect on breast cancer-related LE is inconclusive. We aimed to explore effects of HBOT on early breast cancer-related LE and the implications for QOL. METHODS: We invited women with breast cancer treated with surgery, axillary dissection and radiotherapy, who had participated in a randomized controlled trial and who presented with LE 1 year after surgery. In a prospective observational study design, change in LE was assessed with perometry, dual-energy X-ray absorptiometry (DXA) and lymphoscintigraphy, and QOL by validated self-report scales. Participants were offered 40 sessions of HBOT on every weekday for 8 weeks and were followed for 6 months. RESULTS: Out of 50 eligible participants, 20 women accepted participation. Nineteen women initiated and completed treatment and follow-up. None of the objective measures of LE severity showed consistent changes during the study period, but participants reported significant improvements in QOL (physical functioning, fatigue, insomnia and breast and arm symptoms), with improvements peaking at 6-month follow-up. CONCLUSION: Participants receiving HBOT experienced improved QOL without consistently significant changes in arm mass, volume or lymphatic drainage. These results call for studies into differential effect in patient sub-groups, and a large-scale, randomized placebo-controlled trial with long-term follow-up to assess the effect of HBOT in patients with soft tissue radiation injuries after breast cancer seems warranted.

BACKGROUND: Many cancer survivors experience late effects after cancer. Comorbidity, health literacy, late effects, and help-seeking behavior may affect healthcare use and may differ among socioeconomic groups. We examined healthcare use among cancer survivors, compared with cancer-free individuals, and investigated educational differences in healthcare use among cancer survivors. METHODS: A Danish cohort of 127,472 breast, prostate, lung, and colon cancer survivors from the national cancer databases, and 637,258 age- and sex-matched cancer-free individuals was established. Date of entry was 12 months after diagnosis/index date (for cancer-free individuals). Follow-up ended at death, emigration, new primary cancer, December 31st, 2018, or up to 10 years. Information about education and healthcare use, defined as the number of consultations with general practitioner (GP), private practicing specialists (PPS), hospital, and acute healthcare contacts 1-9 years after diagnosis/index date, was extracted from national registers. We used Poisson regression models to compare healthcare use between cancer survivors and cancer-free individuals, and to investigate the association between education and healthcare use among cancer survivors. RESULTS: Cancer survivors had more GP, hospital, and acute healthcare contacts than cancer-free individuals, while the use of PPS were alike. One-to-four-year survivors with short compared to long education had more GP consultations (breast, rate ratios (RR) = 1.28, 95% CI = 1.25-1.30; prostate, RR = 1.14, 95% CI = 1.10-1.18; lung, RR = 1.18, 95% CI = 1.13-1.23; and colon cancer, RR = 1.17, 95% CI = 1.13-1.22) and acute contacts (breast, RR = 1.35, 95% CI = 1.26-1.45; prostate, RR = 1.26, 95% CI = 1.15-1.38; lung, RR = 1.24, 95% CI = 1.16-1.33; and colon cancer, RR = 1.35, 95% CI = 1.14-1.60), even after adjusting for comorbidity. One-to-four-year survivors with short compared to long education had less consultations with PPS, while no association was observed for hospital contacts. CONCLUSION: Cancer survivors used more healthcare than cancer-free individuals. Cancer survivors with short education had more GP and acute healthcare contacts than survivors with long education. To optimize healthcare use after cancer, we need to better understand survivors' healthcare-seeking behaviors and their specific needs, especially among survivors with short education.

The psychological consequences of losing a parent to cancer are unclear. We investigated whether experiencing parental death to cancer before 18 years of age increases the risk of psychotropic medication. We used register data of all children born in Denmark between 1 January 1987 and 31 December 2016 (N = 1,488,846). We assessed rate ratios (RRs) with 95% confidence intervals (CIs) for first redeemed prescription of antidepressants, anxiolytics and hypnotics according to parental death status using Poisson multi-state models. We further examined whether the associations differed according to the gender of the deceased parent, child's age at the time of death or the parental length of illness. Cancer-bereaved children had a significantly increased risk of first prescription of psychotropic medication (rate ratio, RR 1.22, 95% confidence interval, CI 1.10-1.34 for males; RR 1.18, 95% CI 1.09-1.28 for females). Associations were strongest if the parent had the same sex as the child and if the parent died within one year of diagnosis. The risk was highest during the first six months after the loss (RR 2.35, 95% confidence interval, CI 1.48-3.73 for males; RR 1.81, 95% CI 1.17-2.80 for females). Children who lose a parent to cancer, particularly in cases when the disease progressed quickly, may need extra psychological support, especially during the first six months after the death.

Low socioeconomic position (SEP) may be associated with adverse outcomes in patients with myelodysplastic syndromes (MDS) inherent to for example, delayed diagnosis or reduced treatment intensity, but firm evidence is limited. In this study, we examined the association between SEP and clinical outcomes. We conducted a population-based cohort study (2010-2018) of 2233 Danish patients with MDS. SEP measures included individual-level information on education, cohabitation status and income retrieved from Statistics Denmark. Associations between SEP measures and disease severity at diagnosis were examined using binomial regression analysis. Using time-to-event analysis, we examined the association between SEP measures and treatment with allogeneic stem cell transplantation (allo-HSCT), risk of progression to acute myeloid leukemia (AML), and death. Estimates were adjusted for covariates selected based on direct acyclic graphs and reported with 95% confidence intervals. Patients with a short education were more likely to be transfusion-dependent at diagnosis (RR = 1.25, 95% CI: 1.04-1.45) and more likely to be diagnosed with higher risk MDS according to the International Prognostic Scoring System (RR = 1.29, 95% CI: 1.03-1.62), than patients with a long education. We found no clear association between SEP and risk of progression to AML. In adjusted models, the 1-year risk of dying was higher in patients with short versus long education (RR = 1.34, 95% CI: 1.08-1.65), in patients with low versus high income (RR = 1.42, 95% CI: 1.14-1.77), and among patients who lived alone compared to those who lived with a partner (RR = 1.15, 0.98-1.35). These associations persisted after 3 years and 5 years of follow-up. Notably, patients with a short education had a markedly lower rate of undergoing treatment with allo-HSCT compared to patients with a long education (HR = 0.51, 95% CI: 0.31-0.84). In conclusion, low SEP and especially short education, were poor prognostic factors for adverse clinical outcomes among patients with MDS.

OBJECTIVE: Previous studies suggest that sleeping problems are frequent after cervical cancer. However, the evidence on the use of hypnotics is sparse. We investigated if women diagnosed with cervical cancer have an increased risk of using hypnotics and identified risk factors for prolonged use. METHODS: In this nationwide register-based cohort study, 4264 women diagnosed with cervical cancer from 1997 to 2013 and 36,632 cancer-free women were followed in registers until 2016. Prolonged use of hypnotics was defined as more than three prescriptions with no more than three months in between. Data were analysed using Cox proportional hazards regression models and multistate Markov models separately for women with localized and advanced cervical cancer. RESULTS: The rate of first use of hypnotics was substantially increased during the first year after cervical cancer diagnosis compared to cancer-free women (HRlocalized 4.4, 95% CI 3.9-5.1; HRadvanced 8.9, 95% CI 7.5-10.6) and remained markedly increased for up to five years after diagnosis. Dependent on stage of disease and age, 1.4 to 4.7 excess women per 100 with cervical cancer were prolonged users of hypnotics compared to cancer-free women one year after diagnosis. Risk factors for prolonged use of hypnotics were higher age, short education, previous use of antidepressants or anxiolytics, and advanced disease. CONCLUSIONS: Women diagnosed with cervical cancer are at increased risk of prolonged use of hypnotics. For the majority, treatment with hypnotics is initiated within the first year after cancer diagnosis, but the rate of first use is increased for up to five years.

OBJECTIVE: The diagnosis of cancer in a child is a profoundly stressful experience. The impact on parents' somatic health, including lifestyle-related diseases, however, is unresolved. This paper assesses parents' risk of hospitalization with somatic disease after a child's cancer diagnosis. METHODS: We conducted a nationwide population- and register-based study with parents of all children under age 20 diagnosed with cancer in Denmark between 1998 and 2013 and parents of cancer-free children, matched (1:10) on child's age and family type. We estimated HR with 95% CI in Cox proportional hazard models for 13 major International Classification of Diseases-10 disease groups, selected stress- and lifestyle-related disease-groups, and investigated moderation by time since diagnosis, parental sex, and cancer type. RESULTS: Among n = 7797 parents of children with cancer compared with n = 74,388 parents of cancer-free children (51% mothers, mean age 42), we found no overall pattern of increased risk for 13 broad disease groups. We found increases in digestive system diseases (HR 1.06, 95% CI 1.01-1.12), genitourinary system diseases (HR 1.08, 95% CI 1.02-1.14), and neoplasms (HR 1.20, 95% CI 1.13-1.27), the latter attributable mostly to increased rates of tobacco-related cancers and mothers' diet-related cancers. CONCLUSIONS: This is the first attempt to document the impact of childhood cancer on parents' somatic health. With the exception of increased risk for neoplasms, likely due to shared genetic or lifestyle factors, our findings offer the reassuring message, that the burden of caring for a child with cancer does not in general increase parents' risk for somatic diseases.
