Cancer risks in childhood and adolescence among the offspring of immigrants to Sweden

We used the nation-wide Swedish Family-Cancer Database to analyse the risk of nervous system tumours, leukaemia and non-Hodgkin's lymphoma in age groups 0-4 and 0-19 years among Swedish-born offspring of immigrants. The study included 850 000 individuals with an immigrant background, including European, Asian and American parents. We calculated standardised incidence ratios for the above three mal

Cancer risks in second-generation immigrants to Sweden

We used the nationwide Swedish Family-Cancer Database to analyze cancer risks in Sweden-born descendants of immigrants from European and North American countries. Our study included close to 600,000 0-66-year-old descendants of an immigrant father or mother. We calculated standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) for 17 cancer sites using native Swedes as a reference.

Cancer risks in first-generation immigrants to Sweden

We used the nationwide Swedish Family-Cancer Database to analyse cancer risks in 613,000 adult immigrants to Sweden. All the immigrants had become parents in Sweden and their median age at immigration was 24 years for men and 22 years for women. We calculated standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) for 18 cancer sites using native Swedes as a reference. Data were al

Parental cancer as a risk factor for bone cancer : a nation-wide study from Sweden

We used the nation-wide Swedish Family-Cancer Database to analyze the risk for bone cancer in offspring by parental cancers and in siblings of bone cancer probands. Additionally, the risk of second cancer following childhood bone cancer was investigated. In offspring, 1,190 bone cancers were diagnosed between years 1958 and 1996. Groups of offspring were compared by calculating standardized incide

Time trends in the incidence of cervical and other genital squamous cell carcinomas and adenocarcinomas in Sweden, 1958-1996

OBJECTIVES: We wanted to examine reasons for the different incidence trends for cervical squamous cell carcinoma (SCC, declining) and adenocarcinoma (increasing).METHODS: The Swedish Family-Cancer Database on 9.6 million individuals was used to derive incidence trends between 1958 and 1996. Cervical cancers were compared to vaginal and vulvar cancers.RESULTS: A total of 15405 invasive cervical SCC

Age-incidence relationships and time trends in cervical cancer in Sweden

Age-incidence relationships are informative of carcinogenic mechanisms. These have been previously assessed for cervical squamous cell carcinoma (SCC) but not for adenocarcinoma. The aim was to assess by means of age-, period- and cohort-specific analyses and Poisson regression modelling whether the two types of cervical cancer show an age-incidence maximum at a relatively young age, as shown in c

Time trends and occupational risk factors for peritoneal mesothelioma in Sweden

Epidemiologic data on peritoneal mesothelioma are scarce but exposure to asbestos is an identified risk factor. To characterize the disease, time trends, age-incidence relationships, and occupational risk factors for peritoneal mesothelioma were studied based on the Swedish Family-Database covering years 1961 to 1998. Peritoneal mesothelioma is a rare disease and only 96 male and 113 female cases

Familial upper aerodigestive tract cancers : incidence trends, familial clustering and subsequent cancers

Familial risks in upper aerodigestive tract cancer have been assessed mainly through case-control studies based on reported but not medically verified cancers in family members. The nationwide Swedish Family-Cancer Database was used to describe the incidence trends for all subsites of upper aerodigestive tract cancer and to calculate standardized incidence ratios (SIRs) and 95% confidence interval

Familial and second lung cancers : a nation-wide epidemiologic study from Sweden

The role of hereditary factors in tumor development has been less well understood for lung cancer than for many other human neoplastic diseases. The nation-wide Swedish Family-Cancer Database was used on 10.2 million individuals and 4524 lung cancers to calculate standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) for histological subtypes of lung cancer in 0-66-year-old offspr

Familial and second primary pancreatic cancers : a nationwide epidemiologic study from Sweden

Familial risk of pancreatic cancer has been mainly assessed through case-control studies based on reported but not medically verified cancers in family members. We used the nationwide Swedish Family-Cancer Database on 10.2 million individuals and 21,000 pancreatic cancers to calculate standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) for pancreatic cancer in 0- to 66-year-old

Cancer risks in Nordic immigrants and their offspring in Sweden

Numerous migrant studies on cancer have been carried out, but little data are available on cancer incidence upon inter-European migration. We used the nationwide Swedish Family-Cancer Database to analyse cancer risk among Nordic immigrants and their offspring in Sweden. The parental population had entered Sweden in their 20s and they had become parents in Sweden. Finns were the largest immigrant g

Familial risk of cancer by site and histopathology

Familial risks for histopathology-specific cancers have not been determined. We used the nationwide Swedish Family-Cancer Database on 10.2 million individuals and 1 million tumors to calculate standardized incidence ratios (SIRs) for familial cancers of specific histology and morphology among 0- to 66-year-old offspring. We used histology codes for both offspring and parents, but because of the li

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

We used the nationwide Swedish Family-Cancer Database to analyse cancer risks in women who have had children with different men. Cancer cases were retrieved from the Swedish Cancer Registry for 1961-1998. A total of 3 million women and 316 497 cancer cases were covered. For women having children with more than one partner, an increased risk was shown for upper aerodigestive tract, anal, liver, pan

The nation-wide Swedish family-cancer database--updated structure and familial rates

The Swedish Family-Cancer Database was expanded to include all Swedes born in 1932 and later (offspring) with their parents, totaling 10.2 million individuals. Cancer cases were retrieved from the Swedish Cancer Registry from the years 1958 to 1998, including over 1 million primary cancers and in situ tumors. Some 10%, of offspring diagnosed with cancer lack any parental information. Incidence rat

Familial colorectal adenocarcinoma from the Swedish Family-Cancer Database

Familial risks for colorectal (CRC) adenocarcinoma were characterized from the Swedish Family-Cancer Database covering 9.6 million individuals, whose family relationships and cancers were obtained from registered sources, not sensitive to reporting or ascertainment bias. Cancer cases were retrieved from the Swedish Cancer Registry from years 1958-96. Standardized incidence ratios (SIRs) were calcu

Familial carcinoid tumors and subsequent cancers : a nation-wide epidemiologic study from Sweden

Carcinoids are rare neuroendocrine tumors, mainly located in the bowel, stomach and lung. Familial risks in carcinoid tumours are not well known apart from multiple endocrine neoplasia 1 (MEN1). We used the nation-wide Swedish Family-Cancer Database on 10.1 million individuals for assessment. Carcinoid tumors were retrieved from the Cancer Registry covering the years 1958-1998. The offspring gener

A population-based study of familial central nervous system hemangioblastomas

We used the nationwide Swedish Family-Cancer Database to analyze the risk for central nervous system hemangioblastoma (HB) in offspring (0-61 years) of parents with cancer. Eighty-three offspring were identified, and the age at onset showed a bimodal distribution. The early-onset component peaked at 25-29 years, was associated with von Hippel-Lindau (VHL) disease and presented with HBs, renal cell

Incidence trends and risk factors of carcinoid tumors : a nationwide epidemiologic study from Sweden

BACKGROUND: Carcinoids are rare indolent neuroendocrine tumors, mainly located in bowel, stomach, and lung. Their etiology is virtually unknown although a family history is a minor cause.METHODS: Site specific incidence trends and several risk factors of carcinoid tumors were studied based on the nationwide Swedish Family-Cancer Database of 10.2 million individuals and their more than 1 million tu
