1. Aetiologic heterogeneity in pediatric Hodgkin lymphoma? Evidence from the Nordic countries, 1978-2010.

    Acta Oncologica 55(1):85 (2016) PMID 26073450

    In epidemiological studies, Hodgkin lymphomas (HL) in children younger than 15 years and HL in adolescents and younger adults age 15-35 years has traditionally been studied separately, under the assumption that HL at age 0-14 constitute a homogeneous entity. However, the continued validity of th...
  2. The epidemiology of pituitary adenomas in Iceland, 1955-2012: a nationwide population-based study.

    European Journal of Endocrinology 173(5):655 (2015) PMID 26423473

    Pituitary adenomas (PA) are among the most common human neoplasms. To describe the epidemiology and assess the disease burden of clinically significant PAs, population-based studies are needed. Iceland has a small well-defined population. The aim of this study is to describe the epidemiology of ...
  3. A DNA methylation-based definition of biologically distinct breast cancer subtypes.

    Molecular Oncology 9(3):555 (2015) PMID 25468711

    In cancer, epigenetic states are deregulated and thought to be of significance in cancer development and progression. We explored DNA methylation-based signatures in association with breast cancer subtypes to assess their impact on clinical presentation and patient prognosis. DNA methylation was...
  4. [Thyroid cancer in Iceland in the period 1955-2004. A clinico-pathological and epidemiological study].

    Laeknabladid 97(2):83 (2011) PMID 21339522

    Thyroid cancer has been unusually common in Iceland. Histological classification and TNM-staging has altered somewhat in the last decades. The aim of this study was to investigate the epidemiology of thyroid cancer in Iceland over half a century and identify factors affecting survival. Informati...
  5. A melanoma epidemic in Iceland: possible influence of sunbed use.

    American Journal of Epidemiology 172(7):762 (2010) PMID 20813801

    Since 1980, sunbed use and travel abroad have dramatically increased in Iceland (64°-66°N). The authors assessed temporal trends in melanoma incidence by body site in Iceland in relation to sunbed use and travel abroad. Using joinpoint analysis, they calculated estimated annual percent changes (...
  6. The size of colon polyps revisited: intra- and inter-observer variations.

    Anticancer Research 30(6):2419 (2010) PMID 20651402

    It has been postulated that the occurrence of invasive carcinoma in a colon adenoma can be predicted by estimating the size of the resected polyp. Recently, significant intra- and inter-observer differences in size were found when 22 pathologists estimated the size of 12 polyp phantoms. In this ...
  7. NORDCAN--a Nordic tool for cancer information, planning, quality control and research.

    Acta Oncologica 49(5):725 (2010) PMID 20491528

    The NORDCAN database and program ( www.ancr.nu ) include detailed information and results on cancer incidence, mortality and prevalence in each of the Nordic countries over five decades and has lately been supplemented with predictions of cancer incidence and mortality; future extensions include...
