Understanding quality data correctly: a randomized comparison of presentation formats among cancer patients and relatives.

Patient representatives are increasingly engaged in quality in health care, and even though quality data are publicly available, correct interpretation may be challenging. We designed a randomized study with the primary aim to examine the association between preferred data presentation format and the interpretation of quality data among cancer patients and relatives. Surveys were distributed to the Danish Cancer Society Citizens' Panel between 31 March and 14 April 2019 and 55% completed the survey ( = 464) including six storyboards that presented authentic quality data in table format, league table and point estimates.

Proportion and stage distribution of screen-detected and non-screen-detected colorectal cancer in nine European countries: an international, population-based study.

Background: The effects of recently implemented colorectal cancer screening programmes in Europe on colorectal cancer mortality will take several years to be fully known. We aimed to analyse the characteristics and parameters of screening programmes, proportions of colorectal cancers detected through screening, and stage distribution in screen-detected and non-screen-detected colorectal cancers to provide a timely assessment of the potential effects of screening programmes in several European countries.

Methods: We conducted this population-based study in nine European countries for which data on mode of detection were available (Belgium, Denmark, England, France, Italy, Ireland, the Netherlands, Slovenia, and Spain).

Updated fraction of cancer attributable to lifestyle and environmental factors in Denmark in 2018.

Environmental exposures and avoidable risk factors account for a large proportion of cancer burden. Exposures and lifestyle vary over time and between populations, which calls for updated and population-specific quantification of how various avoidable risk factors influence cancer risk to plan and design rational and targeted prevention initiatives. The study considered 12 risk-factor groups categorized as class I carcinogens by IARC/WCRF.

The influence of marital status and partner concordance on participation in colorectal cancer screening.

Background: Colorectal cancer screening program using a fecal immunochemical test aims to reduce morbidity and mortality through early detection. Although screening participation is free-of-charge, almost 40% of the invited individuals choose not to participate. To bring new insight into how non-participation can be identified and targeted, we examined the association between marital status and screening participation; with a focus on partner concordance in participation and sex differences.

Occult primary brain cancers manifesting in the aftermath of ischaemic and haemorrhagic stroke.

Introduction: Symptoms of occult brain cancer may mimic stroke. Misdiagnosis may lead to improper treatment and delayed diagnosis. We characterised strokes associated with occult primary brain cancer and determined risk that ischaemic and haemorrhagic strokes are associated with occult primary brain cancer.

Occult lung cancer manifesting within the first year after stroke.

Background: Lung cancer and stroke share smoking as a major cause of disease. We investigated prevalence and risk of occult lung cancer with manifestation during the first year after stroke.

Methods: All patients >40 years of age with incident stroke in Denmark 2003-2015 were identified through the Danish Stroke Registry (n=85,893) and matched 1:10 on age and sex to the Danish background population without a history of stroke (n=858,740).

Types of occult cancer in stroke and the relation to smoking.

Objectives: Stroke is associated with a higher risk of occult cancer. We studied the types of occult cancer most often associated with stroke.

Materials And Methods: All patients with incident stroke in Denmark 2003-2015 were identified through the Danish Stroke Registry (n = 85 893) and matched 1:10 on age and sex to the Danish background population without history of stroke (n = 858 740).

Prevalence and risk of occult cancer in stroke.

Objectives: Cancer is associated with higher risk of stroke. Whether this translates into higher risk of cancer in stroke of an extent calling for cancer screening in stroke is unclear. We investigated prevalence and risk of occult cancer in stroke compared to the background population without history of stroke.
