Pathways to myeloproliferative neoplasm presentation and time to diagnosis: results from a cross-sectional study.

BACKGROUND

Early cancer recognition is key to improving patient outcomes. Diagnosis is often delayed in patients with myeloproliferative neoplasms (MPNs), putting them at risk of thromboembolic events and other complications pre-diagnosis. A clear understanding of the barriers to presentation and diagnosis is required.

AIM

To explore barriers and factors influencing delayed presentation and diagnosis of MPNs.

DESIGN & SETTING: A cross-sectional study of patients with MPN within the UK and the Republic of Ireland.

METHOD

An online cross-sectional survey of patients with MPN was undertaken. Symptoms and factors influencing patient and GP delay were examined. Adjusted odds ratios (aORs) were calculated to explore the relationship between these factors and patient and GP delay.

RESULTS

Most (80.2%) of the 620 patients completing the survey reported symptomatic presentation. The most common symptoms associated with patient delay were pruritus (aOR 1.89, 95% confidence interval [CI] = 1.19 to 3.01), headaches (aOR 1.86, 95% CI = 1.13 to 2.82), and concentration difficulties (aOR 1.75, 95% CI = 1.12 to 2.76). Attributing symptoms to ageing (aOR 1.92, 95% CI = 1.19 to 3.11) and not wanting to burden the GP (2.04, 95% CI = 1.24 to 3.39) were significantly associated with patient delay. Those reporting >3 blood cancer warning signs were more likely to experience GP delay than those experiencing fewer (aOR 3.26 95% CI = 1.75 to 6.29), and lack of relational continuity of GP care was significantly associated with GP delay (aOR 3.41, 95% CI = 1.65 to 7.28).

CONCLUSION

Debunking misconceptions around ageing, encouraging timely communication with GPs, and improving relational continuity of GP care could assist in reducing diagnostic delays, prevent potentially fatal disease complications, and ultimately improve outcomes for patients with MPN.
