Second primary malignancies in patients with male breast cancer

An international multicentre study of first and second primary neoplasms associated with male breast cancer was carried out by pooling data from 13 cancer registries. Among a total of 3409 men with primary breast cancer, 426 (12.5%) developed a second neoplasia; other than breast cancer, a 34% overall excess risk of second primary neoplasia, affecting the small intestine (standardised incidence ra

Familial multiple primary lung cancers : a population-based analysis from Sweden

Multiple primary cancers arise because of inherited or acquired deficiencies, and their causes may depend on the first primary cancer, or they may be entirely independent. We used a nation-wide family dataset to search for evidence for a genetic predisposition to lung cancer. The Swedish Family-Cancer Database includes all Swedes born in 1932 and later with their parents, totalling over 10.2 milli

Inherited predisposition to early onset lung cancer according to histological type

The role of hereditary factors in lung cancer is less well understood than in many other human neoplastic diseases. We used a nation-wide family dataset to search for evidence for a genetic predisposition in lung cancer. The Swedish Family-Cancer Database includes all Swedes born in 1932 and later (0- to 68-year-old offspring) with their parents, totaling over 10.2 million individuals. Cancer case

Familial risk in testicular cancer as a clue to a heritable and environmental aetiology

We used the nation-wide Swedish Family-Cancer Database to examine the risk for testicular cancer in offspring through parental and sibling probands. Among 0-68-year-old offspring, 4082 patients had testicular cancer in years 1961-2000, among whom 68 (1.67%) had an affected father/brother. Standardized incidence ratios (SIRs) for familial risk were four-fold when a father and nine-fold when a broth

University and medical education and the risk of cancer in Sweden

Socio-economic gradients are known to exist in cancer but we want to focus on the university-educated population and specifically on physicians to find out whether their special educational background on cancer causation helps them to avoid cancers. The analysis was based on the latest update of the Swedish Family-Cancer Database, in which the educational level was obtained from the national censu

Familial risk of lymphoproliferative tumors in families of patients with chronic lymphocytic leukemia : results from the Swedish Family-Cancer Database

The importance of genetic factors in etiology of chronic lymphocytic leukemia (CLL) is suggested by family and population studies. However, the spectrum of malignancies sharing common genetic factors with CLL and the effects of sex and age on familial risk are unknown. We used the Swedish Family-Cancer Database to test for increased familial risks of CLL and other lymphoproliferative tumors. Cance

Age-specific familial risks for renal cell carcinoma with evidence on recessive heritable effects

BACKGROUND: Systematic comparisons of mode of inheritance for renal cell carcinoma (RCC) have not been carried out. The occurrence of cancer in parents and offspring may be due to dominant causes, whereas cancer affecting only siblings may indicate a recessive causation. Environmental effects need to be excluded.METHODS: The Swedish Family-Cancer Database includes all Swedes born after 1931 with t

Familial risks of cancer as a guide to gene identification and mode of inheritance

Occurrence of cancer in parents and offspring may be due to dominant causes, whereas cancer affecting only siblings may indicate a recessive causation. Systematic comparisons of mode of inheritance have not been available for most types of cancer. Using the Swedish Family-Cancer Database, standardized incidence ratios (SIR) were calculated for offspring whose parents or siblings were diagnosed wit

Association of brain tumours with other neoplasms in families

We used the nationwide Swedish Family-Cancer Database to analyse the association of histology-specific brain tumours with other cancers in family members. Among 0-68-year-old offspring, 9414 patients with brain tumours were identified from 1961 to 2000, of whom, 3387 parents were diagnosed with any primary neoplasm. Astrocytoma, meningioma and neurinoma were the main histological types. Increased

Familial risks in nervous system tumors

We used the nationwide Swedish Family-Cancer Database to analyze the risk for nervous system tumors in offspring through parental and sibling probands. Among 0-68-year-old offspring, close to 11000 patients with a nervous system tumor were identified in years 1961 to 2000, among whom 199 had a parent diagnosed with a nervous system tumor. Brain tumors constituted 86% of all tumors, and astrocytoma

Familial risk of cancer : data for clinical counseling and cancer genetics

Familial risks for cancer are important for clinical counseling and understanding cancer etiology. Medically verified data on familial risks have not been available for all types of cancer. The nationwide Swedish Family-Cancer Database includes all Swedes born in 1932 and later (0-to 68-year-old offspring) with their parents, totaling over 10.2 million individuals. Cancer cases were retrieved from

Familial risk of urological cancers : data for clinical counseling

Familial risks for cancer are important for clinical counseling and understanding cancer etiology. The nationwide Swedish Family-Cancer Database includes all Swedes born in 1932 and later (0 to 68-year-old offspring) with their parents, totaling over 10.2 million individuals. Urological cancer cases were retrieved from the Swedish Cancer Registry up to year 2000. Standardized incidence ratios (SIR

Difference in the risk profiles of carotid-femoral pulse wave velocity : results from two community-based studies in China and Sweden

Carotid-femoral pulse wave velocity (cfPWV) and its risk factors may differ between various populations. Few studies have compared the risk profiles associated with cfPWV in different ethnic populations. The study population included 4321 subjects from Shanghai, China (n = 1272, age 75.0 ± 6.5 years, female 57.3%) and Malmö, Sweden (n = 3049, age 72.5 ± 5.5 years, female 60.4%). cfPWV was measured

Cancer risks in men who had children with different partners from the Swedish Family-Cancer Database

We used the nation-wide Swedish Family-Cancer Database to analyse cancer risks in men who had had children with more than one woman. Cancer cases were retrieved from the Swedish Cancer Registry from years 1961-1998. A total of 2.9 million men and 298,134 cancer cases were covered. For men having children with two, three or more women, increasing risk trends were shown for upper aerodigestive tract

Lifestyle and cancer : effect of widowhood and divorce

Limited data are available on the possible changes in cancer risk brought about by widowhood and divorce, an increasing segment of the population. We calculated standardized incidence ratios (SIRs) for cancer among 47,000 widows/widowers and 60,000 divorced people, based on the Swedish Family-Cancer Database. Persons had to be identified with the same civil status in the census of years 1960 and 1

Familial aggregation of Hodgkin lymphoma and related tumors

BACKGROUND: The importance of genetic factors in the etiology of Hodgkin lymphoma (HL) has been suggested by family and population studies. However, the spectrum of malignancies associated with common genetic etiology and the effects of gender and age on familial risk have not been established.METHODS: Diagnoses of lymphoproliferative malignancies were compared in 15,799 first-degree relatives of
