The length of the polymorphic CAG repeat in the N-terminal of the androgen receptor (AR) gene is inversely correlated with the transactivation function of the AR. Some studies have indicated that short CAG repeats are related to higher risk of prostate cancer. We performed a case-control study to investigate relations between CAG repeat length and prostate cancer risk, tumour grade, tumour stage,

The objectives of this study were to investigate the effect of family history on prostate cancer risk, to estimate the incidence of hereditary prostate cancer in southern Sweden and to assess the reliability of self-reported family history of prostate cancer. The study included consecutive prostate cancer patients and age-matched control subjects from a geographically defined population. The contr

BACKGROUND: Carriers of germline mutations in the BRCA2 gene are known to be at high risk of breast and ovarian cancers, but the risks of other cancers in mutation carriers are uncertain. We investigated these risks in 173 breast-ovarian cancer families with BRCA2 mutations identified at 20 centers in Europe and North America.METHODS: Other cancer occurrence was determined in a final cohort of 372

In this population-based, case-control study from Sweden using data collected from 1988 to 1990, an increased risk of melanoma was associated with the number of sunburns, propensity to freckle, the number of raised naevi and a family history of melanoma. Furthermore, a decreased risk was associated with occupational sun exposure. The purpose of this study was to investigate whether different histo

Various new prognostic indicators have been identified for mammary carcinomas, but the issue of their significance remains unsettled. The prognostic impact of p53, c-erbB-2, and topoisomerase II alpha expression was investigated in relation to standard prognostic factors for carcinomas of the breast and to the tumour cell growth fraction. Paraffin-embedded specimens of 356 node-negative infiltrati

BACKGROUND AND OBJECTIVES: Blood transfusion has been shown to be a risk factor for non-Hodgkin's lymphoma (NHL).MATERIALS AND METHODS: In a cohort of 77,928 women with bleeding complications at delivery in the period of 1973-1986, subsequent NHL cases were identified and the number was compared with the number expected from national incidence rates. In a case-control study the proportion of trans

BACKGROUND: Women with mutations in either the BRCA1 or the BRCA2 gene have a high lifetime risk of ovarian cancer. Oral contraceptives protect against ovarian cancer in general, but it is not known whether they also protect against hereditary forms of ovarian cancer.METHODS: We enrolled 207 women with hereditary ovarian cancer and 161 of their sisters as controls in a case-control study. All the

OBJECTIVE: The aim of this study was to describe the clinical characteristics of early onset prostate cancer, with special reference to family history as a possible prognostic factor.MATERIAL AND METHODS: We identified all cases of prostate cancer diagnosed before the age of 51 in the Southern health care region in Sweden between 1958 and 1994. Clinical data were collected retrospectively from med

Wegener's granulomatosis (WG) and microscopic polyangiitis (MPA) are both frequently associated with antineutrophil cytoplasmic autoantibodies (ANCA). Immunosuppressive treatment has dramatically improved outcome for these patients, but today we have to deal with the problems of relapses, cases refractory to treatment, and long-term side effects of therapy. This study comprises a consecutive serie

Previous studies have indicated that hereditary prostate cancer is common among men with early onset prostate cancer. The aim of this study was to investigate the incidence of malignant tumours in first-degree relatives of men with early onset prostate cancer. All prostate cancer cases diagnosed before the age of 51 years from 1958 to 1994 were identified in the population-based Swedish Cancer Reg

PURPOSE: Recent studies indicate that BRCA1 breast and ovarian tumors may have an advantageous survival. In this population-based study, the survival of carriers of a mutated BRCA1 gene was investigated.PATIENTS AND METHODS: The survival of 71 BRCA1-associated cancer patients (33 breast cancer, seven breast and ovarian cancer, and 31 ovarian cancer patients from 21 families with BRCA1 germline mut

OBJECTIVES: To study attitudes regarding possible inheritance of prostate cancer among sons of men with prostate cancer.METHODS: A questionnaire was sent to 69 men with prostate cancer and their 101 unaffected sons. All participants were also interviewed by telephone. Sociodemographic data were collected, as were data about the fathers' disease.RESULTS: The response rate was high; 100 sons (99%) a

The human genome contains a large variety of sequences related to the mouse mammary tumor virus (MMTV). We have investigated the range of expression of human endogenous retroviral sequences (HERVs) related to MMTV (human MMTV-like; HML) as RNA in 60 breast cancers, 8 nonmalignant breast tissues, and 9 placentas. This was monitored using HML group-specific oligonucleotide probes in hybridizations t

BRCA1 and BRCA2 mutations confer increased risk for development of breast cancer, but a number of additional, currently largely unknown, somatic genetic defects must also accumulate in the breast epithelial cells before malignancy develops. To evaluate the nature of these additional somatic genetic defects, we performed a genome-wide survey by comparative genomic hybridization on breast cancers fr

BRCA1 mutations, although implicated in disease predisposition in a major part of the hereditary breast cancer population, do not seem to be crucially involved in tumorigenesis of sporadic breast and ovarian cancers. This suggests that tumours arising in BRCA1 mutation carriers may differ from BRCA1 negative hereditary and sporadic cancer in genetic and biological features, as well as in clinical

BACKGROUND: There is a worldwide increase in the incidence of cutaneous malignant melanoma (CMM) among whites. In Sweden, a five-fold increase has been recorded since 1960, although the increase in mortality rate is substantially lower. Tumor thickness is recognized as the most important histologic prognostic factor for primary melanoma. In a previous study, the authors did not find any significan

Clustering of testicular cancer cases in families is well known, although the aetiology is not. We present the results of a segregation analysis performed with the algorithm Pointer on familial data on 978 Scandinavian patients with testicular cancer. The segregation analysis favoured the involvement of major gene effects over models incorporating solely polygenic effects in testicular cancer aeti
