- Background Colorectal cancer (CRC) diagnostics are challenging in primary care and reliable diagnostic aids are desired. Qualitative faecal immunochemical tests (FITs) have been used for suspected CRC in Sweden since the mid-2000s, but evidence regarding their effectiveness is scarce. Anaemia and thrombocytosis are both associated with CRC. Aim To evaluate the usefulness of qualitative FITs requested for symptomatic patients in primary care, atone and combined with findings of anaemia and thrombocytosis, in the diagnosis of CRC. Design and setting A population-based cohort study using electronic health records and data from the Swedish Cancer Register, covering five Swedish regions. Method Patients aged >= 18 years in the five regions who had provided FITs requested by primary care practitioners from 1 January 2015 to 31 December 2015 were identified. FIT and blood-count data were registered and all CRC diagnoses made within 2 years were retrieved. Diagnostic measurements were calculated. Results In total, 15 789 patients provided FITs (four different brands); of these patients, 304 were later diagnosed with CRC. Haemoglobin levels were available for 13 863 patients, and platelet counts for 10 973 patients. Calculated for the different FIT brands only, the sensitivities for CRC were 81.6%-100%; specificities 65.7%-79.5%: positive predictive values 4.7%-8.1%; and negative predictive values 99.5%-100%. Calculated for the finding of either a positive FIT or anaemia, the sensitivities increased to 88.9-100%. Adding thrombocytosis did not further increase the diagnostic performance. Conclusion Qualitative FITs requested in primary care seem to be useful as rule in tests for referral when CRC is suspected. A negative FIT and no anaemia indicate a low risk of CRC.
