Primary Sjögren's Syndrome: A Retrospective Cohort Study of Burden of Illness in Sweden.

Introduction: Primary Sjögren's syndrome (pSS) is an autoimmune disease that affects salivary and lachrymal glands and is associated with complex extraglandular manifestations. This study investigates the clinical and economic burden and disease course of pSS in Sweden.

Methods: This retrospective cohort study utilizes data from Swedish national registries and consists of patients at least 18 years of age diagnosed in secondary care with pSS, and matched members of the Swedish general population.

Inhaled corticosteroids and the risk of type 2 diabetes among Swedish COPD patients.

This study reports the association of ICS use and the risk of type 2 diabetes mellitus (T2DM) in Swedish patients with COPD using data from real-world, primary care settings. A total of 7078 patients with COPD were included in this analysis and the 5-year cumulative incidence rate per 100,000 person years was 1506.9.

Agreement between the Danish Cancer Registry and the Danish Lung Cancer Registry.

Introduction: The Danish Cancer Registry (DCR) and the Danish Lung Cancer Registry (DLCR) are nation-wide registries recording Danish patients with lung cancer (LC). The aim of this study was to assess data agreement and possible consequences hereof on estimation of survival between patients in the two registries.

Methods: Descriptive statistics were used for comparison of registered patients in 2013-2014 in the DCR and the DLCR.

Agreement between the Danish Cancer Registry and the Danish Colorectal Cancer Group Database.

The Danish Cancer Registry (DCR) and the Danish Colorectal Cancer Group (DCCG) database are population-based registries collecting information on Danish patients with colorectal cancer (CRC). DCR registers all patients with incident CRC whereas DCCG records patients with first time CRC. The registries use different inclusion criteria.

Early death in Danish stage I lung cancer patients: a population-based case study.

Objective: Clinical stage (c-stage) at diagnosis is the most significant prognostic marker for patients with cancer, where 1- and 5-year survival rates as main landmarks when assessing outcomes. This is a population-based case study of Danish c-stage I lung cancer patients who were considered candidates for curative therapy and then died within 1 year after diagnosis (cases). Cases were identified in the Danish Lung Cancer Register (DLCR), and medical records were used to retrieve treatment details and cause of death (CoD).

Assessing the pattern of recurrence in Danish stage I lung cancer patients in relation to the follow-up program: are we failing to identify patients with cerebral recurrence?

Background: There is paucity of evidence regarding the optimal follow-up (FU) regimen for lung cancer. Consequently, FU is organized differently across countries. The Danish FU regimen has short FU intervals with a computed tomography (CT) scan of the chest and upper abdomen every three months in the early phase (first 2 years), then every six months in the late phase of FU (3rd, 5th year).

Risk factors for patient-reported errors during cancer follow-up: Results from a national survey in Denmark.

Unlabelled: Due to an increased cancer survival, more cancer patients are referred to follow-up after primary treatment. Knowledge of patient safety during follow-up is sparse.

Objective: To examine patient-reported errors during cancer follow-up and identify factors associated with errors.

Incidence and survival in patients with cutaneous melanoma by morphology, anatomical site and TNM stage: a Danish Population-based Register Study 1989-2011.

Introduction: The incidence of melanoma of the skin has risen in Denmark in recent decades, the increase being steeper from 2004. It is unclear whether this represents a true rise in incidence or whether it is caused by an increased awareness of the condition.

Methods: To assess whether the increase was characterised by early-stage melanomas and a higher proportion of melanomas with superficial spreading morphology, we studied all skin melanoma patients registered in the Danish Cancer Register 1989-2011 (n=27,010) and followed up for death through 2013.

Improved survival of Danish cancer patients 2007-2009 compared with earlier periods.

Introduction: For the majority of cancers, improved long-term survival may be accessed from survival during the first year after diagnosis. A steady improvement in survival was seen both before and after the introduction of cancer control plans in 2000 and 2005. On the basis of data from 2007-2009, we studied the trend in 1-year survival after the introduction of the 2005 plan.

Marriage and divorce among childhood cancer survivors.

Many childhood cancer survivors have psychosocial late effects. We studied the risks for cohabitation and subsequent separation. Through the Danish Cancer Register, we identified a nationwide, population-based cohort of all 1877 childhood cancer survivors born from 1965 to 1980, and in whom cancer was diagnosed between 1965 and 1996 before they were 20 years of age.

Leaving home after cancer in childhood: a measure of social independence in early adulthood.

Background: Previous studies on psychosocial outcomes for childhood and adolescent cancer survivors have found diverse results concerning social independence. As a measure of social independence, we investigated whether cancer survivors displayed the same patterns of leaving home as population-based control group.

Procedure: We identified 1,597 patients in the Danish Cancer Register, born in 1965-1980, in whom a primary cancer was diagnosed before they reached the age of 20 in the period 1965-1995.
