Non-specific symptoms-based pathways for diagnosing less common cancers in primary care: a service evaluation

BACKGROUND: Although less common cancers account for almost half of all cancer diagnoses in England, their relative scarcity and complex presentation, often with non-specific symptoms, means that patients often experience multiple primary care consultations, long times to diagnosis, and poor clinical outcomes. An urgent referral pathway for non-specific symptoms, the Multidisciplinary Diagnostic Centre (MDC), may address this problem. AIM: To examine the less common cancers identified during the MDC pilots and consider whether such an approach improves the diagnosis of these cancers. DESIGN AND SETTING: A service evaluation of five MDC pilot projects in England from December 2016 to March 2019. METHOD: Data items were collected by pilot sites in near-real time, based mainly on the English cancer outcomes and services dataset, with additional project-specific items. Simple descriptive and comparative statistics were used, including χ(2) tests for proportions and t-tests for means where appropriate. RESULTS: From 5134 referrals, 378 cancers were diagnosed, of which 218 (58%) were less common. More than 30 different less common tumour types were diagnosed in this cohort. Of the MDC patients with less common cancers, 23% (n = 50) had ≥3 GP consultations before referral and, at programme level, a median time of 57 days was recorded from GP urgent referral to treatment for these tumour types. CONCLUSION: A non-specific symptomatic referral route diagnoses a broad range of less common cancers, and can support primary care case management for patients with symptoms of possible cancer that do not qualify for a site-specific urgent referral.
