The contribution of a negative colorectal screening test result to symptom appraisal and help‐seeking behaviour among patients subsequently diagnosed with an interval colorectal cancer

摘要

Abstract Background Colorectal cancer ( CRC ) screening programmes using a guaiac faecal occult blood test ( gFOB t) reduce CRC mortality. Interval cancers are diagnosed between screening rounds: reassurance from a negative gFOB t has the potential to influence the pathway to diagnosis of an interval colorectal cancer. Methods Twenty‐six semi‐structured face‐to‐face interviews were carried out in Scotland and England, with individuals diagnosed with an interval colorectal cancer following a negative gFOB t result. Results Participants reported they were reassured by a negative gFOB t, interpreting their result as an “all clear”. Therefore, most did not suspect cancer as a possible cause of symptoms and many did not recall their screening result during symptom appraisal. Among those who did consider cancer, and did think about their screening test result, reassurance from a negative gFOB t led some to “downplay” the seriousness of their symptoms with some interviewees explicitly stating that their negative test result contributed to a delayed decision to seek help. Conclusion Screening participants need to be informed of the limitations of screening and the ongoing risk of developing colorectal cancer even when in receipt of a negative result: the importance of minimizing delay in seeking medical advice for colorectal symptoms should be emphasized.
