Progress against lung cancer, Denmark, 2008-2022.

Background And Purpose: There has been marked progress against lung cancer in Denmark. To gain further insight into the different aspects of the improvement, we examined the stage-specific incidence rates, stage-specific survival and mortality rates.

Materials And Methods: We used information from the Danish Lung Cancer Registry on date of diagnosis and clinical stage to calculate age-standardised incidence rates and patient survival by sex, period and stage.

Thin or early melanoma, risk factors and associated mortality.

Introduction: The incidence of thin and early-stage melanoma is increasing in many populations, but the clinical significance of these lesions remains partly unknown.

Methods: Firstly, melanoma deaths in Denmark (2009-2018) were followed back to establish melanoma debut in these persons. Secondly, using national registries of cancer incidence and mortality, 27,036 persons with thin or early-stage melanoma were followed-up for melanoma death.

Regional and socio-economic variation in survival after glioblastoma in Denmark, 2013-2018.

Introduction: Glioblastoma is the most frequent primary brain tumour in adults. In Denmark, the treatment of glioblastoma is centralised to four neurosurgical and oncological departments located in four of the five Danish administrative regions. The aim of this study was to examine the regional and socioeconomic variation in survival after a diagnosis of glioblastoma in Denmark.

Methods: In a nationwide cohort of Danish women from 1984 to 2013, incidence of adhesive bowel obstruction and 30 days mortality were presented as standardized rates.

Regional and socio-economic variation in survival after a pancreatic cancer diagnosis in Denmark.

Introduction: Pancreatic cancer is among the most lethal malignancies with a five-year survival of about 5%, and the only curative treatment is surgical resection. Denmark consists of five governmental regions and has four surgical centres. Our aim was to explore the regional and socio-economic differences in overall survival following a pancreatic cancer diagnosis in Denmark.

Regional and socioeconomic variation in survival of melanoma patients in Denmark.

Introduction: This article explores variation in survival and mortality of Danish melanoma patients from 2012 to 2017 in relation to their region of residence and socioeconomic status.

Methods: Data were extracted from The Danish Melanoma Database, a clinical register, based on reports from hospital departments and dermatologists, and designed for quality improvement. The analysis included covariates at the person and tumour level.

Risk of adhesive bowel obstruction after abdominal surgery. A national cohort study of 665,423 Danish women.

Background: Adhesive bowel obstruction is associated with considerable morbidity and mortality, but the magnitude of the risk is debated.

Method: In a national cohort of all Danish women with an abdominal operation (N = 665,423) between 1977 and 2013, the risk of adhesive bowel obstruction was assessed by Cox multiple regression. Covariates were the number of abdominal operations, the surgical methods, the anatomical site involved, and the calendar year.

Influence of socioeconomic factors and region of residence on cancer stage of malignant melanoma: a Danish nationwide population-based study.

Background: Socioeconomic differences in survival after melanoma may be due to late diagnosis of the disadvantaged patients. The aim of the study was to examine the association between educational level, disposable income, cohabitating status and region of residence with stage at diagnosis of melanoma, including adjustment for comorbidity and tumor type.

Methods: From The Danish Melanoma Database, we identified 10,158 patients diagnosed with their first invasive melanoma during 2008-2014 and obtained information on stage, localization, histology, thickness and ulceration.

Does stage of cancer, comorbidity or lifestyle factors explain educational differences in survival after endometrial cancer? A cohort study among Danish women diagnosed 2005-2009.

Background: Several studies have documented an association between socioeconomic position and survival from gynaecological cancer, but the mechanisms are unclear.

Objective: The aim of this study was to examine the association between level of education and survival after endometrial cancer among Danish women; and whether differences in stage at diagnosis and comorbidity contribute to the educational differences in survival.

Methods: Women with endometrial cancer diagnosed between 2005 and 2009 were identified in the Danish Gynaecological Cancer Database, with information on clinical characteristics, surgery, body mass index (BMI) and smoking status.

Do stage of disease, comorbidity or access to treatment explain socioeconomic differences in survival after ovarian cancer? - A cohort study among Danish women diagnosed 2005-2010.

Aims: In order to reduce social inequality in cancer survival, knowledge is needed about where in the cancer trajectory disparities occur, and how social and health-related aspects may interact. We aimed to determine whether socioeconomic factors are related to cancer diagnosis stage, and whether socioeconomic disparities in survival after ovarian cancer can be explained by socioeconomic differences in cancer stage, comorbidity, treatment or lifestyle factors.

Methods: In the Danish Gynaecological Cancer Database we identified 2873 cases of ovarian cancer diagnosed between 2005 and 2010.

Socioeconomic position and survival after lung cancer: Influence of stage, treatment and comorbidity among Danish patients with lung cancer diagnosed in 2004-2010.

Background: To address social inequality in survival after lung cancer, it is important to consider how socioeconomic position (SEP) influences prognosis. We investigated whether SEP influenced receipt of first-line treatment and whether socioeconomic differences in survival could be explained by differences in stage, treatment and comorbidity.

Material And Methods: In the Danish Lung Cancer Register, we identified 13 045 patients with lung cancer diagnosed in 2004-2010, with information on stage, histology, performance status and first-line treatment.

Socioeconomic position and stage at diagnosis of head and neck cancer - a nationwide study from DAHANCA.

Background: Socioeconomic differences in survival after head and neck squamous cell carcinoma (HNSCC) are among the greatest for any malignancy. To improve our understanding of the mechanisms by which socioeconomic position influences HNSCC survival, we investigated the association between socioeconomic position and advanced stage HNSCC at diagnosis.

Material And Methods: Men and women with HNSCC diagnosed between 1992 and 2008 were identified in the Danish Head and Neck Cancer Group (DAHANCA) database, which contains detailed information on all cases of HNSCC treated in Denmark.

Who are the cancer survivors? A nationwide study in Denmark, 1943-2010.

Background: No nationwide studies on social position and prevalence of comorbidity among cancer survivors exist.

Methods: We performed a nationwide prevalence study defining persons diagnosed with cancer 1943-2010 and alive on the census date 1 January 2011 as cancer survivors. Comorbidity was compared by social position with the non-cancer population.

Methods: We studied survival in relation to income and level of education in all patients aged >40 years admitted to hospital for stroke in Denmark in 2003 to 2012.

Risk of contralateral breast cancer after tamoxifen use among Danish women.

Purpose: Tamoxifen reduces the risk of contralateral breast cancer (CBC), but little is known about the long-term risk.

Methods: From the database under the Danish Breast Cancer Cooperative Group (DBCG), we identified 15,863 users and 21,670 nonusers of tamoxifen among women diagnosed with breast cancer during 1977 to 2007. Information on CBC was obtained from the Danish Cancer Registry and the Danish Breast Cancer Cooperative Group database.

Socioeconomic position and incidence of ischemic stroke in Denmark 2003-2012. A nationwide hospital-based study.

Background: A greater burden of stroke risk factors in general is associated with a higher risk for stroke among people of lower than those of higher socioeconomic position. The relative impact of individual stroke risk factors is still unclear.

Methods And Results: We studied the relations between socioeconomic position, measured as household income and length of education, and all hospital admissions for a first ischemic stroke among 54 048 people over the age of 40 years in Denmark in 2003-2012 in comparison with the general Danish population (23.

Socioeconomic position and survival after cervical cancer: influence of cancer stage, comorbidity and smoking among Danish women diagnosed between 2005 and 2010.

Background: In an attempt to decrease social disparities in cancer survival, it is important to consider the mechanisms by which socioeconomic position influences cancer prognosis. We aimed to investigate whether any associations between socioeconomic factors and survival after cervical cancer could be explained by socioeconomic differences in cancer stage, comorbidity, lifestyle factors or treatment.

Methods: We identified 1961 cases of cervical cancer diagnosed between 2005 and 2010 in the Danish Gynaecological Cancer database, with information on prognostic factors, treatment and lifestyle.

Affiliation to the work market after curative treatment of head-and-neck cancer: a population-based study from the DAHANCA database.

Objectives: Survivors of squamous cell carcinoma of the head and neck (HNSCC) are more severely affected in regard to affiliation to the work market than other cancer survivors. Few studies have investigated associations between socioeconomic and disease-related factors and work market affiliation after curative treatment of HNSCC. We investigated the factors for early retirement pension due to disability and unemployment in patients who had been available for work one year before diagnosis.

Effect of mindfulness-based stress reduction on sleep quality: results of a randomized trial among Danish breast cancer patients.

Unlabelled: The prevalence of sleep disturbance is high among cancer patients, and the sleep problems tend to last for years after the end of treatment. As part of a large randomized controlled clinical trial (the MICA trial, NCT00990977) of the effect of mindfulness-based stress reduction (MBSR) on psychological and somatic symptoms among breast cancer patients, the aim of the current study was to evaluate the effect of MBSR on the secondary outcome, 'sleep quality'.

Material And Methods: A total of 336 women operated on for breast cancer stage I-III 3-18 months previously were randomized to MBSR (n = 168) or treatment as usual (n = 168); both groups received standard clinical care.

Socioeconomic position and surgery for early-stage non-small-cell lung cancer: A population-based study in Denmark.

Aim: To examine possible associations between socioeconomic position and surgical treatment of patients with early-stage non-small-cell lung cancer (NSCLC).

Methods: In a register-based clinical cohort study, patients with early-stage (stages I-IIIa) NSCLC were identified in the Danish Lung Cancer Register 2001-2008 (date of diagnosis, histology, stage, and treatment), the Central Population Register (vital status), the Integrated Database for Labour Market Research (socioeconomic position), and the Danish Hospital Discharge Register (comorbidity). Logistic regression analyses were performed overall and separately for stages I, II and IIIa.

Psychiatric disorders in women with fertility problems: results from a large Danish register-based cohort study.

Study Question: Do women who don't succeed in giving birth after an infertility evaluation have a higher risk of psychiatric disorders compared with women who do?

Summary Answer: The results indicated that being unsuccessful in giving birth after an infertility evaluation could be an important risk factor for psychiatric disorders.

What Is Known Already: Several studies have investigated the association between fertility treatment and psychological distress, but the results from these studies show substantial variation and lack of homogeneity that may be due to methodological limitations.

Study Design, Size And Duration: A retrospective cohort study was designed using data from a cohort of 98 320 Danish women evaluated for fertility problems during 1973-2008 and linked to several Danish population-based registries.

All-cause mortality among men whose cohabiting partner has been diagnosed with cancer.

Background: Previous studies suggest that spouses of cancer patients are at increased risk for several chronic diseases. We investigated mortality in relation to cancer morbidity in the stable female partner.

Methods: We established a national retrospective cohort study of 1,422,131 men who had lived continuously with the same partner for at least 5 years and used Cox regression analysis to assess the association between experiencing cancer in a cohabiting partner and all-cause mortality.

Socioeconomic position and stage of cervical cancer in Danish women diagnosed 2005 to 2009.

Background: To reduce social disparities in cervical cancer survival, it is important to understand the mechanisms by which social position influence cancer prognosis. We investigated the relations between socioeconomic factors, comorbidity, time since last Papanicolau smear, and stage at diagnosis in Danish women with cervical cancer.

Methods: We identified 1,651 cervical cancer cases diagnosed 2005 to 2009 from the Danish Gynaecological Cancer Database.

Socioeconomic position, treatment, and survival of non-Hodgkin lymphoma in Denmark--a nationwide study.

Background: Not all patients have benefited equally from the advances in non-Hodgkin lymphoma (NHL) survival. This study investigates several individual-level markers of socioeconomic position (SEP) in relation to NHL survival, and explores whether any social differences could be attributed to comorbidity, disease and prognostic factors, or the treatment given.

Methods: This registry-based cohort study links clinical data on prognostic factors and treatment from the national Danish lymphoma database to individual socioeconomic information in Statistics Denmark including 6234 patients diagnosed with NHL in 2000-2008.
