Objective: The objective of this study was to examine the associations between socioeconomic/Occupational factors and histologic subtypes of leukemia. Methods: The Swedish Family-Cancer Database was used to calculate standardized incidence ratios for different social classes and occupational groups. Results: The overall standardized incidence ratio was close to unity between different socioeconomi
Although many studies have examined the associations between occupational exposures and kidney cancer, the evidence is not consistent. To examine the risk of occupational exposures on kidney cancer, we carried out a follow-up study on the economically active Swedish population, based on the latest update of the Swedish Family-Cancer Database. We calculated standardized incidence ratios (SIR) and 9
Objectives: We sought to examine the associations between occupation and upper aerodigestive tract cancers at various anatomic sites. Methods: The Swedish Family-Cancer Database was used to calculate standardized incidence ratios for different occupational groups, adjusted for age, period, and socioeconomic status. Results: Male dentists showed an increased risk for tongue cancer; hairdressers had
In a follow-up study of occupational exposures and bladder cancer, an increased risk was observed after an adjustment for smoking, for physicians, administrators and managers, clerical workers and sales agents among men and assistant nurses among women. For physicians, the reason may be early diagnosis; for the other groups a sedentary type of work may have a role in bladder cancer aetiology.
Objectives: To examine the associations between socioeconomic/occupational factors and liver cancer at various anatomic sites (including primary liver, gallbladder and other cancers). Methods: We carried out a follow-up study on the economically active Swedish population, based on the Swedish Family-Cancer Database. Standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) were calcu
Purpose: The present study aimed at quantifying risks for second malignancies in patients with bone cancers, and risks for second bone cancers after other primary tumors. Methods: Adjusted standardized incidence ratios (SIRs) were used as a measure of risk. Results: Among 2,546 primary bone cancer patients, a total of 171-second malignancies occurred. Besides second bone cancers, other cancer site
The effects of socio-economic/occupational factors on gastric cancer at various subsites (including corpus, cardia and unspecified cancers) are not well known. To investigate this issue, we carried out a follow-up study on the economically active Swedish population, based on the Swedish Family-Cancer Database. We calculated standardized incidence ratios and 95% confidence intervals for different o
Objective: The objective of this study was to examine the associations between socioeconomic/occupational factors and pancreatic cancer. Methods: The Swedish Family-Cancer Database was used to calculate standardized incidence ratios for different social classes and occupational groups. Lung cancer risks were also determined. The reference group was all the economically active population. Results:
Characteristics of the built environment, including access to unhealthy food outlets, are hypothesized to contribute to type 2 diabetes mellitus (T2D). Swedish nationwide registry data on 4,718,583 adults aged 35-80 years living in 9,353 neighborhoods, each with at least 1 food outlet, were geocoded and linked to commercial registers (e.g., restaurants and grocery stores). Multilevel logistic regr
AIMS: Some 15% of the Swedish population is born outside Sweden, originating from all continents of the world. Thalassemia and sickle cell anemia constitute the most common inherited recessive disorders globally and they are endemic in areas of Africa and Asia, origins of many immigrants to Sweden. We aimed at investigating the origins of the Swedish sickle cell and thalassemia patients.METHODS: P
Reliable data on familial risks are important for clinical counseling and cancer genetics. We wanted to study incidence trends and familial risks for pituitary adenomas and associated tumors through parental and sibling probands, using the nation-wide Swedish Family-Cancer Database on 10.5 million individuals, containing families with parents and offspring. Cancer data were retrieved from the Swed
The reasons for the high risk of contralateral breast cancer are not understood, although polygenic mechanisms have been suggested to be involved. The nationwide Swedish Family-Cancer Database was used to examine the interaction of the risks for contralateral and familial cancer. Relative risks were separately determined for contralateral and familial breast cancers, and these were tested for addi
The concentrations of endogenous hormones differ between women with twin and singleton births, with a possible influence on the risk of cancer. We used the nationwide Swedish Family-Cancer Database, including 30,409 women with a twin birth, to examine the subsequent risks of breast, endometrial, and ovarian cancers. Relative risks (RRs) were calculated in a log-linear Poisson regression model of p
Having family members with cancer has been associated with increased risk for bladder and renal cell cancers, but its association with survival has not been examined. This study was an analysis of the nationwide Swedish Family-Cancer Database and revealed that survival for bladder and renal cell cancers was similar whether the cancer was familial or sporadic; however, when survival in offspring wa
PURPOSE: Several earlier studies have assessed survival in prostate cancer based on familial risk of this disease. As a novel concept, we posit that factors governing survival in prostate cancer are likely to be different from those governing risk of prostate cancer. To prove this, we searched for familial clustering of survival (ie, concordance of survival among family members).PATIENTS AND METHO
OBJECTIVES: To estimate sibling risk of hospitalization for children with sleep disordered breathing (SDB), diagnosed with (1) obstructive sleep apnea syndrome (OSAS), or (2) adenotonsillar hypertrophy in the total Swedish population.DESIGN, SETTING, AND PARTICIPANTS: Using the MigMed database at the Karolinska Institute, we divided the population of Sweden aged 0-18 years into sibling groups base
The population attributable fraction (PAF) defines the proportion of a disease that would be prevented if the exposure to a particular risk factor was avoided. Familial risk is a known risk factor for many cancers, but an unbiased estimation of the PAF for familial risk requires a large study population to include rare cancers. PAFs and their corresponding standardized incidence ratios (SIRs) were
