The value of using the faecal immunochemical test in general practice on patients presenting with non-alarm symptoms of colorectal cancer.

BACKGROUND: Around 50% of individuals with colorectal cancer (CRC) initially present with non-alarm symptoms. METHODS: We investigated the value of using the faecal immunochemical test (FIT) in the diagnostic process of CRC and other serious bowel disease in individuals presenting with non-alarm symptoms in general practice. The study was conducted in the Central Denmark Region from 1 September 2015 to 30 August 2016. The FIT was used as a rule-in test on patients aged ≥30 years with non-alarm symptoms of CRC. The cut-off value was set to 10 µg Hb/g faeces. RESULTS: A total of 3462 valid FITs were performed. Of these, 540 (15.6%) were positive. Three months after FIT performance, 51 (PPV: 9.4% (95% CI: 7.0;11.9)) individuals with a positive FIT were diagnosed with CRC and 73 (PPV: 13.5% (95%CI: 10.6;16.4)) with other serious bowel disease. Of CRCs, 66.7% were diagnosed in UICC stage I & II and 19.6% in stage IV. The false negative rate for CRC was <0.1% for the initial 3 months after FIT performance. CONCLUSION: The FIT may be used as a supplementary diagnostic test in the diagnostic process of CRC and other serious bowel disease in individuals with non-alarm symptoms of CRC in general practice.

Differences in diagnostic activity in general practice and findings for individuals invited to the danish screening programme for colorectal cancer: a population-based cohort study.

OBJECTIVE: To investigate the diagnostic activity in general practice and the cumulative incidence of colorectal cancer (CRC) in individuals invited to the Danish national screening programme for CRC. DESIGN: A historical population-based cohort study. SETTING: The Danish CRC screening programme and general practice. SUBJECTS: The 376,198 individuals invited to the Danish CRC screening programme from 1 March to 31 December 2014. MAIN OUTCOME MEASURES: The diagnostic activity (consultations and haemoglobin measures) in general practice in the year preceding the screening invitation and the cumulated incidence of CRC in the year following the screening invitation. RESULTS: Screening participants had significantly higher diagnostic activity than non-participants. Individuals with a positive faecal immunochemical test (FIT) had higher diagnostic activity compared to individuals with a negative FIT, and a small increase in the months leading up to the invitation. Individuals with a screen-detected CRC had lower diagnostic activity than individuals with no CRC. In total, 308 (25.3%) of CRCs diagnosed in the invited population were diagnosed outside the screening programme. Non-participants with CRC more often had low socio-economic status, high comorbidity and stage IV CRC than participants with CRC. CONCLUSIONS: There was a tendency that participants and those with a positive FIT had a higher diagnostic activity the year before the screening. This was not seen for those with CRC detected through screening. CRC must still be diagnosed in general practice in the invited population and non-participants are of special interest as they have higher risk of late stage CRC. Key Points Current awareness:Individuals with colorectal cancer (CRC) in screening may be symptomatic and CRC may still occur outside screening in the invited population. Most important points:The majority of individuals with CRC in screening cannot be expected to be diagnosed on symptomatic presentation in general practice GPs have to be aware that CRC still occurs outside screening in the invited population Non-participants with CRC are often deprived and have late stage CRC.

Implementation of immunochemical faecal occult blood test in general practice: a study protocol using a cluster-randomised stepped-wedge design.

BACKGROUND: Colorectal cancer is a common malignancy and a leading cause of cancer-related death. Half of patients with colorectal cancer initially present with non-specific or vague symptoms. In the need for a safe low-cost test, the immunochemical faecal occult blood test (iFOBT) may be part of the evaluation of such patients in primary care. Currently, Danish general practitioners have limited access to this test. The aim of this article is to describe a study that will assess the uptake and clinical use of iFOBT in general practice. Furthermore, it will investigate the diagnostic value and the clinical implications of using iFOBT in general practice on patients presenting with non-alarm symptoms of colorectal cancer. METHODS/DESIGN: The study uses a cluster-randomised stepped-wedge design and is conducted in the Central Denmark Region among 836 GPs in 381 general practices. The municipalities of the Region and their appertaining general practitioners will be included sequentially in the study during the first 7 months of the 1-year study period. The following intervention has been developed for the study: a mandatory intervention providing all general practitioners with a starting package of 10 iFOBTs, a clinical instruction on iFOBT use in general practice and online information material from the date of inclusion, and an optional intervention consisting of a continuous medical education on colorectal cancer diagnostics and use of iFOBT. DISCUSSION: This study is among the first and largest trials to investigate the diagnostic use and the clinical value of iFOBT on patients presenting with non-alarm symptoms of colorectal cancer. The findings will be of national and international importance for the future planning of colorectal cancer diagnostics, particularly for 'low-risk-but-not-no-risk' patients with non-alarm symptoms of colorectal cancer. TRIAL REGISTRATION: A Trial of the Implementation of iFOBT in General Practice NCT02308384 . Date of registration: 26 November 2014.

[Uncharacteristic colorectal cancer symptoms and their value in general practice]. / Ukarakteristiske symptomer hos patienter med debut af kolorektal cancer i almen praksis.

Though colorectal cancer is one of the most common cancers in Denmark, there is a serious lack of knowledge in general practice about symptom presentation. The prevalence and the positive predictive value of the so-called alarm symptoms are vague, and screening will only detect a small number of cancers per year. In the future, general practice will still play an important role in the diagnosis of colorectal cancer; therefore, knowledge about how the disease presents in general practice is urgently needed, and intervention studies on how to optimize early diagnosis should be encouraged.

[Improved prognosis in light chain nephropathy due to multiple myeloma]. / Forbedret prognose ved letkædenefropati ved myelomatose.

A 64 year-old woman with acute renal failure and cast nephropathy due to excessive production of lambda free light chains received chemotherapy (using bortezomib and dexamethason) and haemodialysis with a high cut off-filter. The concentration of free light chains was markedly reduced after a fortnight. Nine months after admission, the patient's kidney function had improved and dialysis was stopped. Three months later, she got an autologous stem cell transplantation. One year later, estimated glomerular filtration rate was 25 ml/min, and the production of free light chains was under control.
