    • Infectious etiologies have been hypothesized for acute leukemias because of their high incidence in early childhood, but have seldom been examined for acute myeloid leukemia (AML). We conducted the first large cohort study to examine perinatal factors including season of birth, a proxy for perinatal infectious exposures, and risk of AML in childhood through young adulthood. A national cohort of 3,569,333 persons without Down syndrome who were born in Sweden in 1973-2008 were followed up for AML incidence through 2010 (maximum age 38 years). There were 315 AML cases in 69.7 million person-years of follow-up. We found a sinusoidal pattern in AML risk by season of birth (P < 0.001), with peak risk among persons born in winter. Relative to persons born in summer (June-August), incidence rate ratios for AML were 1.72 (95 % CI 1.25-2.38; P = 0.001) for winter (December-February), 1.37 (95 % CI 0.99-1.90; P = 0.06) for spring (March-May), and 1.27 (95 % CI 0.90-1.80; P = 0.17) for fall (September-November). Other risk factors for AML included high fetal growth, high gestational age at birth, and low maternal education level. These findings did not vary by sex or age at diagnosis. Sex, birth order, parental age, and parental country of birth were not associated with AML. In this large cohort study, birth in winter was associated with increased risk of AML in childhood through young adulthood, possibly related to immunologic effects of early infectious exposures compared with summer birth. These findings warrant further investigation of the role of seasonally varying perinatal exposures in the etiology of AML.

  • Perinatal risk factors for Wilms tumor in a Swedish national cohort
  • 2014
  • Ingår i: European Journal of Epidemiology. - : Springer. - 1573-7284. ; 29:3, s. 191-197
  • Tidskriftsartikel (refereegranskat)abstract
    • Perinatal risk factors including high birth weight have been associated with Wilms tumor in case-control studies. However, these findings have seldom been examined in large cohort studies, and the specific contributions of gestational age at birth and fetal growth remain unknown. We conducted the largest population-based cohort study to date consisting of 3,571,574 persons born in Sweden in 1973-2008, followed up for Wilms tumor incidence through 2009 to examine perinatal risk factors. There were 443 Wilms tumor cases identified in 66.3 million person-years of follow-up. After adjusting for gestational age and other perinatal factors, high fetal growth was associated with increased risk of Wilms tumor among girls (hazard ratio per 1 standard deviation (SD), 1.36; 95 % CI 1.20-1.54; P < 0.001), but not boys (1.10; 95 % CI 0.97-1.25; P = 0.14) (P (interaction) = 0.02). Among girls, high fetal growth was associated with disease onset before age 5 years (odds ratio per 1 SD, 1.47; 95 % CI 1.28-1.69; P < 0.001), but not beyond (1.00; 95 % CI 0.76-1.31; P = 0.99). No clear associations were found for gestational age at birth or other perinatal factors. In this large cohort study, high fetal growth was associated with Wilms tumor before age 5 years among girls. These findings suggest that early-life growth factor pathways for Wilms tumor may be more common among girls than boys. Further elucidation of these mechanisms may reveal better targets for prevention or treatment of specific subtypes of Wilms tumor.

  • Physical fitness among swedish military conscripts and long-term risk for type 2 diabetes mellitus a cohort study
  • 2016
  • Ingår i: Annals of Internal Medicine. - : American College of Physicians. - 0003-4819. ; 164:9, s. 577-584
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Early-life physical fitness has rarely been examined in relation to type 2 diabetes mellitus (DM) in adulthood because of the lengthy follow-up required. Elucidation of modifiable risk factors at young ages may help facilitate earlier and more effective interventions. Objective: To examine aerobic capacity and muscle strength at age 18 years in relation to risk for type 2 DM in adulthood. Design: National cohort study. Setting: Sweden. Participants: 1 534 425 military conscripts from 1969 to 1997 (97% to 98% of all men aged 18 years nationwide) without prior type 2 DM. Measurements: Aerobic capacity and muscle strength (measured in watts and newtons per kilogram of body weight, respectively) were examined in relation to type 2 DM identified from outpatient and inpatient diagnoses from 1987 to 2012 (maximum age, 62 years). Results: 34 008 men were diagnosed with type 2 DM in 39.4 million person-years of follow-up. Low aerobic capacity and muscle strength were independently associated with increased risk for type 2 DM. The absolute difference in cumulative incidence of type 2 DM between the lowest and highest tertiles of both aerobic capacity and strength was 0.22% at 20 years of follow-up (95% CI, 0.20% to 0.25%), 0.76% at 30 years (CI, 0.71% to 0.81%), and 3.97% at 40 years (CI, 3.87% to 4.06%). Overall, the combination of low aerobic capacity and muscle strength was associated with a 3-fold risk for type 2 DM(adjusted hazard ratio, 3.07 [CI, 2.88 to 3.27]; P <0.001), with a positive additive interaction (P <0.001). These associations were seen even among men with normal body mass index. Limitation: This cohort did not include women and did not measure physical fitness at older ages. Conclusion: In this large cohort of Swedish male military conscripts, low aerobic capacity and muscle strength at age 18 years were associated with increased long-term risk for type 2 DM, even among those with normal body mass index.

  • Pre-term delivery and long-term risk of heart failure in women : a national cohort and co-sibling study
  • 2023
  • Ingår i: European Heart Journal. - : Oxford University Press. - 1522-9645.
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: Women who deliver pre-term have higher future risks of hypertension and ischaemic heart disease, but long-term risks of heart failure (HF) are unknown. We examined these risks in a large national cohort.METHODS AND RESULTS: All 2 201 284 women with a singleton delivery in Sweden during 1973-2015 were followed up for inpatient or outpatient HF diagnoses through 2015. Cox regression was used to compute hazard ratios (HRs) for HF associated with pregnancy duration, adjusting for other maternal factors. Co-sibling analyses assessed for confounding by shared familial (genetic and/or environmental) factors. In 48.2 million person-years of follow-up, 19 922 women were diagnosed with HF (median age: 60.7 years). Within 10 years after delivery, the adjusted HR was 2.96 [95% confidence interval (CI): 2.48-3.53] for HF associated with pre-term (gestational age: <37 weeks) compared with full-term (39-41 weeks) delivery. Stratified HRs were 4.27 (2.54-7.17) for extremely pre-term (22-27 weeks), 3.39 (2.57-4.48) for moderately pre-term (28-33 weeks), 2.70 (2.19-3.32) for late pre-term (34-36 weeks), and 1.70 (1.45-1.98) for early term (37-38 weeks). These HRs declined but remained elevated at 10-19 years (pre-term vs. full term: HR: 2.19; 95% CI: 1.94-2.46), 20-29 years (1.80; 1.67-1.95), and 30-43 years (1.56; 1.47-1.66) after delivery, and were not explained by shared familial factors.CONCLUSION: Pre-term and early term delivery were associated with markedly increased future hazards for HF, which persisted after adjusting for other maternal and familial factors and remained elevated 40 years later. Pre-term and early-term delivery should be recognized as risk factors for HF across the life course.KEY QUESTION: What are the long-term hazards for heart failure (HF) across the life course in women who deliver preterm?KEY FINDING: Preterm and early term delivery were associated with ∼3- and 1.7-fold adjusted hazards for HF in the next 10 years vs. full-term delivery. These hazards declined but remained elevated 40 years later, and were not explained by shared familial factors.TAKE HOME MESSAGE: Preterm and early term delivery were associated with increased future hazards for HF, which persisted for 40 years after adjusting for other maternal and familial factors. Preterm and early term delivery should be recognized as lifelong risk factors for HF.

  • Risks of Depression and Suicide After Diagnosis With Heart Failure : A National Cohort Study
  • 2022
  • Ingår i: JACC: Heart Failure. - : Elsevier. - 2213-1779. ; 10:11, s. 819-827
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Heart failure (HF) has been associated with psychosocial distress, but other long-term mental health sequelae are unclear. Objectives: In this study, the authors sought to determine risks of major depression and suicide, susceptible time periods, and sex-specific differences after HF diagnosis in a large population-based cohort. Methods: A national cohort study was conducted of all 154,572 persons diagnosed with HF at ages 18-75 years during 2002-2017 in Sweden and 1,545,720 age- and sex-matched population-based control subjects who were followed up for major depression and suicide ascertained from nationwide inpatient, outpatient, and death records through 2018. Poisson regression was used to compute incidence rate ratios (IRRs) while adjusting for sociodemographic factors and comorbidities. Results: HF was associated with increased risks of major depression and death by suicide in both men and women, with highest risks in the first 3 months, then declining to modest risks at ≥12 months after HF diagnosis. Within 3 months after HF diagnosis, adjusted IRRs for new-onset major depression were 3.34 (95% CI: 3.04-3.68) in men and 2.78 (95% CI: 2.51-3.09) in women, and for suicide death were 4.47 (95% CI: 2.62-7.62) in men and 2.82 (95% CI: 1.11-7.12) in women. These risks were elevated regardless of age at HF diagnosis. HF was associated with significantly more depression cases in women (P < 0.001). Conclusions: In this large national cohort, HF was associated with substantially increased risks of depression and suicide in men and women, with highest risks occurring within 3 months after HF diagnosis. Men and women with HF need timely detection and treatment of depression and suicidality.

  • Season of birth and other perinatal risk factors for melanoma.
  • 2014
  • Ingår i: International Journal of Epidemiology. - : Oxford University Press. - 1464-3685. ; 43:3, s. 793-801
  • Tidskriftsartikel (refereegranskat)abstract
    • Ultraviolet radiation (UVR) exposure is the main risk factor for cutaneous malignant melanoma (CMM), but its specific effect in infancy is unknown. We examined whether season of birth, a proxy for solar UVR exposure in the first few months of life, is associated with CMM in childhood through young adulthood.

  • Season of birth and risk of Hodgkin and non-Hodgkin lymphoma
  • 2014
  • Ingår i: International Journal of Cancer. - : John Wiley & Sons Inc.. - 0020-7136. ; 135:11, s. 2735-2739
  • Tidskriftsartikel (refereegranskat)abstract
    • Infectious etiologies have been hypothesized for Hodgkin and non-Hodgkin lymphoma (HL and NHL) in early life, but findings to date for specific lymphomas and periods of susceptibility are conflicting. We conducted the first national cohort study to examine whether season of birth, a proxy for infectious exposures in the first few months of life, is associated with HL or NHL in childhood through young adulthood. A total of 3,571,574 persons born in Sweden in 1973-2008 were followed up through 2009 to examine the association between season of birth and incidence of HL (943 cases) or NHL (936 cases). We found a sinusoidal pattern in NHL risk by season of birth (p = 0.04), with peak risk occurring among birthdates in April. Relative to persons born in fall (September-November), odds ratios for NHL by season of birth were 1.25 [95% confidence interval (CI), 1.04-1.50; p = 0.02] for spring (March-May), 1.22 (95% CI, 1.01-1.48; p = 0.04) for summer (June-August) and 1.11 (95% CI, 0.91-1.35; p = 0.29) for winter (December-February). These findings did not vary by sex, age at diagnosis or major sub-types. In contrast, there was no seasonal association between birthdate and risk of HL (p = 0.78). In this large cohort study, birth in spring or summer was associated with increased risk of NHL (but not HL) in childhood through young adulthood, possibly related to immunologic effects of delayed infectious exposures compared with fall or winter birth. These findings suggest that immunologic responses in early infancy may play an important role in the development of NHL.

  • Copy Number Variants Are Ovarian Cancer Risk Alleles at Known and Novel Risk Loci.
  • 2022
  • Ingår i: Journal of the National Cancer Institute. - 0027-8874 .- 1460-2105. ; 114:11, s. 1533-1544
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Known risk alleles for epithelial ovarian cancer (EOC) account for approximately 40% of the heritability for EOC. Copy number variants (CNVs) have not been investigated as EOC risk alleles in a large population cohort.METHODS: Single nucleotide polymorphism array data from 13 071 EOC cases and 17 306 controls of White European ancestry were used to identify CNVs associated with EOC risk using a rare admixture maximum likelihood test for gene burden and a by-probe ratio test. We performed enrichment analysis of CNVs at known EOC risk loci and functional biofeatures in ovarian cancer-related cell types.RESULTS: We identified statistically significant risk associations with CNVs at known EOC risk genes; BRCA1 (PEOC = 1.60E-21; OREOC = 8.24), RAD51C (Phigh-grade serous ovarian cancer [HGSOC] = 5.5E-4; odds ratio [OR]HGSOC = 5.74 del), and BRCA2 (PHGSOC = 7.0E-4; ORHGSOC = 3.31 deletion). Four suggestive associations (P < .001) were identified for rare CNVs. Risk-associated CNVs were enriched (P < .05) at known EOC risk loci identified by genome-wide association study. Noncoding CNVs were enriched in active promoters and insulators in EOC-related cell types.CONCLUSIONS: CNVs in BRCA1 have been previously reported in smaller studies, but their observed frequency in this large population-based cohort, along with the CNVs observed at BRCA2 and RAD51C gene loci in EOC cases, suggests that these CNVs are potentially pathogenic and may contribute to the spectrum of disease-causing mutations in these genes. CNVs are likely to occur in a wider set of susceptibility regions, with potential implications for clinical genetic testing and disease prevention.

  • No clinical utility of KRAS variant rs61764370 for ovarian or breast cancer
  • 2016
  • Ingår i: Gynecologic Oncology. - : Academic Press. - 0090-8258 .- 1095-6859. ; 141:2, s. 386-401
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective Clinical genetic testing is commercially available for rs61764370, an inherited variant residing in a KRAS 3′ UTR microRNA binding site, based on suggested associations with increased ovarian and breast cancer risk as well as with survival time. However, prior studies, emphasizing particular subgroups, were relatively small. Therefore, we comprehensively evaluated ovarian and breast cancer risks as well as clinical outcome associated with rs61764370. Methods Centralized genotyping and analysis were performed for 140,012 women enrolled in the Ovarian Cancer Association Consortium (15,357 ovarian cancer patients; 30,816 controls), the Breast Cancer Association Consortium (33,530 breast cancer patients; 37,640 controls), and the Consortium of Modifiers of BRCA1 and BRCA2 (14,765 BRCA1 and 7904 BRCA2 mutation carriers). Results We found no association with risk of ovarian cancer (OR = 0.99, 95% CI 0.94-1.04, p = 0.74) or breast cancer (OR = 0.98, 95% CI 0.94-1.01, p = 0.19) and results were consistent among mutation carriers (BRCA1, ovarian cancer HR = 1.09, 95% CI 0.97-1.23, p = 0.14, breast cancer HR = 1.04, 95% CI 0.97-1.12, p = 0.27; BRCA2, ovarian cancer HR = 0.89, 95% CI 0.71-1.13, p = 0.34, breast cancer HR = 1.06, 95% CI 0.94-1.19, p = 0.35). Null results were also obtained for associations with overall survival following ovarian cancer (HR = 0.94, 95% CI 0.83-1.07, p = 0.38), breast cancer (HR = 0.96, 95% CI 0.87-1.06, p = 0.38), and all other previously-reported associations. Conclusions rs61764370 is not associated with risk of ovarian or breast cancer nor with clinical outcome for patients with these cancers. Therefore, genotyping this variant has no clinical utility related to the prediction or management of these cancers.

  • Genome-Wide Meta-Analyses of Breast, Ovarian, and Prostate Cancer Association Studies Identify Multiple New Susceptibility Loci Shared by at Least Two Cancer Types
  • 2016
  • Ingår i: Cancer Discovery. - : AMER ASSOC CANCER RESEARCH. - 2159-8274 .- 2159-8290. ; 6:9, s. 1052-1067
  • Tidskriftsartikel (refereegranskat)abstract
    • Breast, ovarian, and prostate cancers are hormone-related and may have a shared genetic basis, but this has not been investigated systematically by genome-wide association (GWA) studies. Meta-analyses combining the largest GWA meta-analysis data sets for these cancers totaling 112,349 cases and 116,421 controls of European ancestry, all together and in pairs, identified at P < 10 -8 seven new cross-cancer loci: three associated with susceptibility to all three cancers (rs17041869/2q13/BCL2L11; rs7937840/11q12/INCENP; rs1469713/19p13/GATAD2A), two breast and ovarian cancer risk loci (rs200182588/9q31/SMC2; rs8037137/15q26/RCCD1), and two breast and prostate cancer risk loci (rs5013329/1p34/NSUN4; rs9375701/6q23/L3MBTL3). Index variants in five additional regions previously associated with only one cancer also showed clear association with a second cancer type. Cell-type-specific expression quantitative trait locus and enhancer-gene interaction annotations suggested target genes with potential cross-cancer roles at the new loci. Pathway analysis revealed significant enrichment of death receptor signaling genes near loci with P < 10(-5) in the three-cancer meta-analysis. SIGNIFICANCE: We demonstrate that combining large-scale GWA meta-analysis findings across cancer types can identify completely new risk loci common to breast, ovarian, and prostate cancers. We show that the identification of such cross-cancer risk loci has the potential to shed new light on the shared biology underlying these hormone-related cancers. (C) 2016 AACR.
