  1. 1. New evidence on germ-cell testicular cancer aetiology

    Författare :Lorenzo Richiardi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Testicular neoplasm; Seminomas; Nonseminomas; Case-control study; Risk factors; Perinatal characteristics; Body size; Subfertility; Occurrence.;

    Sammanfattning : Testicular cancer has been increasing in incidence for at least 50 years in many populations, but its etiology remains elusive. We investigated several prenatal and postnatal factors in association with germ-cell testicular cancer risk. Moreover, we evaluated recent trends in testicular cancer incidence in Northern European countries. LÄS MER

  3. 2. The significance of placental and placental-like alkaline phosphatases in tumor biology and their potential use in clinical practice

    Författare :Annika Jeppsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alkaline phosphatase; seminoma; eutopic; gynaecological tumors; immunolocalization;

    Sammanfattning : Placental alkaline phosphatase (PLAP) is a membrane bound enzyme normally synthesized by the syncytiotrophoblasts in the human placenta. Recent studies have indicated that trace amounts of placental-like alkaline phosphatases also are present in several normal organs like testes and endocervix. LÄS MER

  4. 3. Etiological insights into the testicular cancer epidemic

    Författare :Olof Akre; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Testicular neoplasms; seminoma; nonseminoma; epidemiology; etiology; risk factors; prenatal; fertility; birth weight; placenta; neonatal jaundice; cryptorchidism; hypospadias; preterm birth; Epstein-Barr virus; cytomegalovirus; Body Mass Index; height;

    Sammanfattning : The aim of this thesis was to search for causes of the testicular cancer epidemic through epidemiologic studies of testicular cancer and possibly related conditions, such as urogenital birth defects and subfertility. First, we assessed changes in fertility over time by studying time-to-pregnancy among primiparous women in Sweden from 1983 through 1993 using data from the Medical Birth Registry. LÄS MER

  5. 4. Cancer and migration : epidemiological studies on relationship between country of birth, socio-economic position and cancer

    Författare :Omid Beiki; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Country of birth; immigrants; breast neoplasm; uterine cervical neoplasm; endometrial neoplasm; ovarian neoplasm; prostatic neoplasm; testicular neoplasm; socio-economic position; incidence; survival; Sweden;

    Sammanfattning : Background: Migrant studies offer a unique opportunity to analyze variation in disease occurrence due to background factors. The role of environmental and lifestyle exposures are of particular interest in cancer research, and migrant studies can be considered as "natural experiments" in epidemiological research. LÄS MER
