Predictive value of abnormal blood tests for detecting cancer in primary care patients with nonspecific abdominal symptoms: A population-based cohort study of 477,870 patients in England

Identifying cancer in patients presenting with nonspecific abdominal symptoms is often difficult, but incorporating abnormal blood test results can significantly enhance diagnostic accuracy. A recent study using data from the UK demonstrated that analysing 19 different abnormal blood tests, alongside the symptoms reported by patients, improves the ability to predict cancer risk. This method was particularly effective for patients aged 60 and older, where the blood tests helped surpass the 3% risk threshold necessary for urgent referral. Additionally, the use of blood test results proved valuable for detecting cancer in patients aged 30 to 59, suggesting that these tests can be instrumental in identifying cancer even in a younger demographic. However, the effectiveness of this approach hinges on the accurate coding of symptoms and the consistent application of blood tests across various healthcare settings. While the study highlights the potential for improved cancer detection and increased urgent referrals, the implementation of such a strategy may vary depending on local practices and resources. Integrating blood test results into cancer risk assessments could lead to earlier and more accurate diagnoses, but careful consideration of the practical aspects of symptom and test data management is essential for optimising outcomes.
