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.
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
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
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 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
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 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
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 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
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 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
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 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 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
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
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
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
Second cancers were studied among 68,104 cases of colorectal cancer (CRC) from the Swedish Family-Cancer Database. A total of 1,113 patients received a diagnosis of second CRC; 25 of them had a family history of CRC. Cases of second CRC with a family history were diagnosed up to 10 years before sporadic cases. The relative risk (RR) of all second CRCs was 2.21 compared with the first CRC. Familial
