  • 2007
  • Ingår i: Scandinavian Journal of Urology and Nephrology. - Taylor & Francis. - 0036-5599. ; 41:6, s. 456-477

    • Objective. The incidence of prostate cancer is rising rapidly in Sweden and there is a need to better understand the pattern of diagnosis, tumor characteristics and treatment. Material and methods. Between 1996 and 2005, all new cases of adenocarcinoma of the prostate gland were intended to be registered in the National Prostate Cancer Register (NPCR). This register contains information on diagnosing unit, date of diagnosis, cause of diagnosis, tumor grade, tumor stage according to the TNM classification in force, serum prostate-specific antigen (PSA) levels at diagnosis and primary treatment given within the first 6 months after diagnosis. Results. In total, 72 028 patients were registered, comprising > 97% of all pertinent incident cases of prostate cancer in the Swedish Cancer Register (SCR). During the study period there was a considerable decrease in median age at the time of diagnosis, a stage migration towards smaller tumors, a decrease in median serum PSA values at diagnosis, a decrease in the age-standardized incidence rate of men diagnosed with distant metastases or with a PSA level of > 100 ng/ml at diagnosis and an increase in the proportion of tumors with Gleason score <= 6. Relatively large geographical differences in the median age at diagnosis and the age-standardized incidence of cases with category T1c tumors were observed. Treatment with curative intent increased dramatically and treatment patterns varied according to geographical region. In men with localized tumors and a PSA level of <20 ng/ml at diagnosis, expectant treatment was more commonly used in those aged >= 75 years than in those aged <75 years. Also, the pattern of endocrine treatment varied in different parts of Sweden. Conclusions. All changes in the register seen over time are consistent with increased diagnostic activity, especially PSA testing, resulting in an increased number of cases with early disease, predominantly tumors in category T1c. The patterns of diagnosis and treatment of prostate cancer vary considerably in different parts of Sweden. The NPCR continues to be an important source for research, epidemiological surveillance of the incidence, diagnosis and treatment of prostate cancer.

  • Prostate Cancer Registration in Four Swedish Regions 1996 : Differences in Incidence, Age Structure and Management
  • 1999
  • Ingår i: Scandinavian Journal of Urology and Nephrology. - 0036-5599. ; 33:5, s. 306-311
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: In 1996 registration of prostate cancer in four of the six Swedish regions was started to facilitate evaluation of geographical variations in incidence and treatment.Material and methods: For all cases of prostate cancer, personal identification number, tumour stage, tumour grade and primary treatment were registered.Results: In the four regions covered by the register, 3541 cases of prostate cancer were registered. Altogether there were 5795 cases of prostate cancer diagnosed in Sweden the same year. The age-standardized incidence varied from 89/100 000 to 169/100 000 among counties. The proportion of localized tumours correlated positively to the incidence (p &amp;lt; 0.05) and negatively to mean age at diagnosis (p &amp;lt; 0.01). There was also a significant positive correlation between the proportion of localized tumours and the percentage of patients given curative treatment. All registered variables showed large geographical variations, especially concerning percentage of T1c tumours, treatment of localized tumours and choice of palliative treatment.Conclusion: Diagnostic activity varied considerably among counties, resulting in large variation in age-standardized incidence. High incidence is associated with a larger proportion of localized tumours, which, in turn, is associated with early age at diagnosis. In counties where a policy of detecting tumours early is practised, curative treatment is also given more often. Treatment of localized tumours and preference for palliative treatment seem to depend on local traditions. The lack of cytological and histopathological standards makes geographical comparisons based on tumour grade impossible.

  • Hundreds of variants clustered in genomic loci and biological pathways affect human height.
  • 2010
  • Ingår i: Nature. - 1476-4687. ; 467:7317, s. 832-8
  • Tidskriftsartikel (refereegranskat)abstract
    • Most common human traits and diseases have a polygenic pattern of inheritance: DNA sequence variants at many genetic loci influence the phenotype. Genome-wide association (GWA) studies have identified more than 600 variants associated with human traits(1), but these typically explain small fractions of phenotypic variation, raising questions about the use of further studies. Here, using 183,727 individuals, we show that hundreds of genetic variants, in at least 180 loci, influence adult height, a highly heritable and classic polygenic trait(2,3). The large number of loci reveals patterns with important implications for genetic studies of common human diseases and traits. First, the 180 loci are not random, but instead are enriched for genes that are connected in biological pathways (P = 0.016) and that underlie skeletal growth defects (P&lt;0.001). Second, the likely causal gene is often located near the most strongly associated variant: in 13 of 21 loci containing a known skeletal growth gene, that gene was closest to the associated variant. Third, at least 19 loci have multiple independently associated variants, suggesting that allelic heterogeneity is a frequent feature of polygenic traits, that comprehensive explorations of already-discovered loci should discover additional variants and that an appreciable fraction of associated loci may have been identified. Fourth, associated variants are enriched for likely functional effects on genes, being over-represented among variants that alter amino-acid structure of proteins and expression levels of nearby genes. Our data explain approximately 10% of the phenotypic variation in height, and we estimate that unidentified common variants of similar effect sizes would increase this figure to approximately 16% of phenotypic variation (approximately 20% of heritable variation). Although additional approaches are needed to dissect the genetic architecture of polygenic human traits fully, our findings indicate that GWA studies can identify large numbers of loci that implicate biologically relevant genes and pathways.

  • Spatial distribution of low-energy plasma around comet 67P/CG from Rosetta measurements
  • 2015
  • Ingår i: Geophysical Research Letters. - 0094-8276 .- 1944-8007. ; 42:11, s. 4263-4269
  • Tidskriftsartikel (refereegranskat)abstract
    • We use measurements from the Rosetta plasma consortium Langmuir probe and mutual impedance probe to study the spatial distribution of low-energy plasma in the near-nucleus coma of comet 67P/Churyumov-Gerasimenko. The spatial distribution is highly structured with the highest density in the summer hemisphere and above the region connecting the two main lobes of the comet, i.e., the neck region. There is a clear correlation with the neutral density and the plasma to neutral density ratio is found to be approximate to 1-210(-6), at a cometocentric distance of 10km and at 3.1AU from the Sun. A clear 6.2h modulation of the plasma is seen as the neck is exposed twice per rotation. The electron density of the collisionless plasma within 260km from the nucleus falls off with radial distance as approximate to 1/r. The spatial structure indicates that local ionization of neutral gas is the dominant source of low-energy plasma around the comet.

  • Meta-analysis identifies 13 new loci associated with waist-hip ratio and reveals sexual dimorphism in the genetic basis of fat distribution.
  • 2010
  • Ingår i: Nature genetics. - 1546-1718. ; 42:11, s. 949-60
  • Tidskriftsartikel (refereegranskat)abstract
    • Waist-hip ratio (WHR) is a measure of body fat distribution and a predictor of metabolic consequences independent of overall adiposity. WHR is heritable, but few genetic variants influencing this trait have been identified. We conducted a meta-analysis of 32 genome-wide association studies for WHR adjusted for body mass index (comprising up to 77,167 participants), following up 16 loci in an additional 29 studies (comprising up to 113,636 subjects). We identified 13 new loci in or near RSPO3, VEGFA, TBX15-WARS2, NFE2L3, GRB14, DNM3-PIGC, ITPR2-SSPN, LY86, HOXC13, ADAMTS9, ZNRF3-KREMEN1, NISCH-STAB1 and CPEB4 (P = 1.9 × 10⁻⁹ to P = 1.8 × 10⁻⁴⁰) and the known signal at LYPLAL1. Seven of these loci exhibited marked sexual dimorphism, all with a stronger effect on WHR in women than men (P for sex difference = 1.9 × 10⁻³ to P = 1.2 × 10⁻¹³). These findings provide evidence for multiple loci that modulate body fat distribution independent of overall adiposity and reveal strong gene-by-sex interactions.

  • Geographical variation in incidence of prostate cancer in Sweden : Survey from the National Prostate Cancer Register
  • 2005
  • Ingår i: Scandinavian Journal of Urology and Nephrology. - 0036-5599. ; 39:5, s. 372-379
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. To investigate the geographical variation in prostate cancer incidence in Sweden, in particular the incidences of screening-detected tumours and curative treatment of prostate cancer. Material and methods. Data were retrieved from the National Prostate Cancer Register of Sweden for all cases of prostate cancer diagnosed in the year 2000-01. There were a total of 14376 cases of prostate cancer and the mean total annual age-adjusted incidence was 197/100000 men. There were 3318 cases in tumour category T1c, i.e. non-palpable tumours diagnosed during work-up for an elevated serum level of prostate-specific antigen, 1006 of which (30%) were asymptomatic and detected at a health check-up. Results. The difference between the counties with the lowest and highest age-adjusted incidences per 1OO 000 men of total prostate cancer was almost twofold (128 vs 217). The corresponding variation in incidence of category Tie tumours was more than fourfold (13 vs 60), the difference in incidence of Tie tumours detected in asymptomatic men was up to 10-fold (2 vs 20), and there was more than a fourfold variation in incidence of curative treatment between counties (13 vs 67). Measured incidences were mostly highest in urban regions and in counties with university hospitals. Conclusion. There are large geographical variations in prostate cancer incidence and in the frequency of curative treatment for prostate cancer in Sweden and there appear to be large geographical variations in the uptake of prostate cancer screening. © 2005 Taylor & Francis.

  • The National Prostate Cancer Register in Sweden 1998-2002 : trends in incidence, treatment and survival
  • 2005
  • Ingår i: Scandinavian Journal of Urology and Nephrology. - 0036-5599 .- 1651-2065. ; 39:2, s. 117-23
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To provide a descriptive review of the establishment of the National Prostate Cancer Register (NPCR) in Sweden, to present clinical characteristics at diagnosis and to calculate the relative survival of different risk groups after 5 years. MATERIAL AND METHODS: Since 1998, data on all newly diagnosed prostate cancers, including TNM classification, grade of malignancy, prostate-specific antigen (PSA) level and treatment, have been prospectively collected. For the 35,223 patients diagnosed between 1998 and 2002, relative survival in different risk groups has been calculated. RESULTS: Between 1998 and 2002, 96% of all prostate cancer cases diagnosed in Sweden were registered in the NPCR. The number of new cases increased from 6137 in 1998 to 7385 in 2002. The age-standardized rate rose in those aged &lt; 70 years, while it was stable, or possibly declining from 1999, in the older age groups. The proportion of T1c tumours increased from 14% to 28% of all recorded cases. The age-adjusted incidence of advanced tumours (M1 or PSA &gt; 100 ng/ml) decreased by 17%. The proportion of patients receiving curative treatment doubled. Patients with N1 or M1 disease or poorly differentiated tumours (G3 or Gleason score 8-10) had a markedly reduced relative 5-year survival rate. CONCLUSIONS: It is possible to establish a nationwide prostate cancer register including basic data for assessment of the disease in the whole of Sweden. The introduction of PSA screening has increased the detection of early prostate cancer in younger men and, to a lesser extent, decreased the incidence of advanced disease. The effect of these changes on mortality is obscure but the NPCR in Sweden will serve as an important tool in such evaluation.

  • Autologous haematopoietic stem cell transplantation for aggressive multiple sclerosis: : the Swedish experience
  • 2014
  • Ingår i: Journal of Neurology, Neurosurgery and Psychiatry. - BMJ Publishing Group. - 0022-3050. ; 85:10, s. 1116-1121
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Autologous haematopoietic stem cell transplantation (HSCT) is a viable option for treatment of aggressive multiple sclerosis (MS). No randomised controlled trial has been performed, and thus, experiences from systematic and sustained follow-up of treated patients constitute important information about safety and efficacy. In this observational study, we describe the characteristics and outcome of the Swedish patients treated with HSCT for MS. Methods Neurologists from the major hospitals in Sweden filled out a follow-up form with prospectively collected data. Fifty-two patients were identified in total; 48 were included in the study and evaluated for safety and side effects; 41 patients had at least 1 year of follow-up and were further analysed for clinical and radiological outcome. In this cohort, 34 patients (83%) had relapsing-remitting MS, and mean follow-up time was 47 months. Results At 5 years, relapse-free survival was 87%; MRI event-free survival 85%; expanded disability status scale (EDSS) score progression-free survival 77%; and disease-free survival (no relapses, no new MRI lesions and no EDSS progression) 68%. Presence of gadolinium-enhancing lesions prior to HSCT was associated with a favourable outcome (disease-free survival 79% vs 46%, p=0.028). There was no mortality. The most common long-term side effects were herpes zoster reactivation (15%) and thyroid disease (8.4%). Conclusions HSCT is a very effective treatment of inflammatory active MS and can be performed with a high degree of safety at experienced centres.

  • Nationwide population-based study on 30-day mortality after radical prostatectomy in Sweden
  • 2009
  • Ingår i: SCANDINAVIAN JOURNAL OF UROLOGY AND NEPHROLOGY. - 0036-5599. ; 43:5, s. 350-356
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. The incidence of prostate cancer in Sweden is increasing rapidly, as is treatment with curative intent. Radical prostatectomy (RP) is currently commonly performed, either within or outside large high-volume centres. The aim of this study was to assess the 30-day mortality rate after RP in Sweden. Material and methods. In this nationwide population-based study, all men diagnosed with localized prostate cancer (andlt;= 70 years, clinical stadium T1-2, prostate-specific antigen andlt;20 ng/ml) who underwent RP in Sweden between 1997 and 2002 were identified through the National Prostate Cancer Register (NPCR). Mortality within 30 days of RP was analysed through linkage between the follow-up study of the NPCR and the Regional Population Registers. The cause of death in the death certificates were compared with data from the hospitals concerned. To validate the results, a record linkage between the Inpatient Register and the National Population Register was also performed. Results. The number of RPs performed increased over time. Among 3700 RPs performed, four deaths occurred during the first 30 days, yielding a 0.11% 30-day mortality rate. These deaths occurred at three different types of hospital and were all probably related to the RP. Conclusion. This study provides further evidence that RP is a procedure with very low perioperative mortality even when performed outside high-volume centres.
