The aim is to develop optimum cancer diagnostic pathways for lung, colon and pancreatic cancers within two clinical commissioning groups (CCGs), using the information generated by the earlier parts of the programme. The project has been developed in line with local and national initiatives and objectives and will be undertaken in NHS Bristol and NHS Sunderland working alongside the local CCGs.
This is a two-centre study in which evidence from earlier phases of DISCOVERY, on the predictive value of symptoms and on patient preference for investigation, will inform a refinement of existing pathways for assessment of patients with suspected cancer. The exemplar cancers will be lung, colorectal and pancreas. The primary outcome of interest will be change in urgent referral metrics (referral ratio, conversion and detection rates) for practices in the two centres. Secondary outcomes will be proportion of cases diagnosed as emergency presentations. The study will take place in NHS Bristol and NHS Sunderland working alongside the local CCGs
A multidisciplinary expert group will be constituted for each site comprising secondary care specialists, GP cancer leads and cancer network directors. The group will work alongside the Discovery team in each area to map and refine diagnostic pathways.
The reference pack
A pack of background information will be developed, to be supplied to the expert group in order to inform their planning. It will contain:
- Information on current practice, with local and national figures to allow comparison.
- Current pathways. To include NICE referral criteria as well as any local adaptation of 2WW pathways currently in operation. Guidance on direct access to investigations as published by DH in 2012. Map of Medicine flowcharts for the three sites.
- Discovery findings. To include Caper study-derived RATs for all three sites with related publications; results of PIVOT; emerging findings from Discovery 3.2
Once adapted pathways have been agreed by the expert group for each centre, they will be presented to the relevant CCG for its endorsement.
Implementation will comprise:
- Mailing to all GPs in each centre of the adapted pathways in user-friendly formats
- Engagement with GP cancer leads, who will be key influencers at local level
- Presentation at a protected learning time event for GPs and at practice manager fora
- Placing of pathways on local intranets aimed at primary care and on trust websites
New Discovery Research publication
The SYMPTOM Study team's research into symptom appraisal for colorectal cancer has been published in BMJ Open. This is a unique piece of research which compares the appraisal and help seeking experiences of patients with colorectal cancer symptoms who go on to have cancer and those who turn out to have non-cancer conditions. The research did not identify any clear differences between the two groups but did identify important barriers to presentation around the ‘private nature’ of colorectal symptoms which will prove useful to policy makers and the design of awareness campaigns.

Discovery conference slides available & new research publications
The Discovery Programme held its research conference at the Royal College of General Practitioners on June 2nd 2015. The team presented their research findings and outlined the impact of the programme to a wide range of patient groups, clinicians, policy makers, researchers and journalists. The PowerPoint slides used during the presentation have been uploaded to this website and can be viewed here.
There are also 2 new research papers to report. Chantal Balasooriya-Smeekens has published the literature review of her PhD in Psycho-Oncology, "The role of emotions in time to presentation for symptoms suggestive of cancer: a systematic review of quantitative studies". Abstract and publication details are here and further papers from Chantal's PhD will be published soon.
Nafees Din has published a new paper under the Discovery related research umbrella. The paper uses Discovery data drawn from the CAPER (theme 2) studies and considers "Age and Gender Variations in Cancer Diagnostic Intervals in 15 Cancers". Full publication details and abstract can be found here.
