PUBLIC AWARENESS

Factors influencing time to presentation: Appraisal: lack of knowledge Help-seeking: avoidance, fatalism, reluctance to seek help (including

embarrassment, wasting the doctor’s time) Be Clear on Cancer campaigns- lung, colorectal cancer Early evidence of effects on:

Awareness GP consultations Use of diagnostic tests Urgent referralsPreliminary results suggest: Impact on stage at diagnosis Trigger presentation

PUBLIC AWARENESS- skin cancer

Walter et al. BMJ Open, in press

Be Clear on Cancer campaigns- skin cancer Melanoma interview study

63 adults aged 29 - 93 Interviewed with 10 weeks of diagnosis

Key results Common features: change in

size, shape, colour Unassuming features: ‘just a

little spot’ Subtly different patterns of

features: ‘vertical growth’ Normal explanations: life

changes

PATIENT PATHWAYS- Symptom Study

What symptoms and other patient factors are associated with later presentation or later stage at diagnosis of lung, colorectal, pancreas cancer? Prospective cohort study: patient questionnaires

and nested qualitative in-depth interviews Setting: East and North East England, patients

referred to urgent, routine & investigative clinics Inclusion criteria: aged ≥40 with symptoms

suspicious of colorectal, lung, pancreatic cancer Recruitment: when referred, mailed SYMPTOM

questionnaire Further data collection: from primary care and

hospital records relating to participants’ symptoms and diagnosis

Inhibiting

Facilitating

“And if I should be out and I get this sort of urge to go to the toilet, I have to go otherwise I’ve pooed myself. .. very embarrassing” (female, 77 years, NC)

“that was probably the thing that put me off going more than anything in the first instance was the embarrassment of that sort of thing. .. I don’t suppose anybody likes, whether it’s a doctor or not, playing around what you consider as your private parts” (Male, 66 years, CRC)

Looking for symptom relief Perceived seriousness and/or

anxiety about cancer Loss of privacy e.g. wind, faecal

incontinence (or fear of) Lack of embarrassment

Prompt help-seeking

Socio-cultural norms Symptom monitoring Embarrassment of investigations

PATIENT VIEWS- ‘private nature of symptoms’me personally, the way I was brought up, one, you don’t talk about downstairs, and two, you don’t look at downstairs. So, when people ask me questions like “Is it in the stool?” or anything like that, I tend not to look, I do now, but I didn’t then” (Female, 54 years, NC)

RISK ASSESSMENT TOOLS for GPs

CAPER studies Main output: risk assessment

tools (RATs) Piloted in 152 practices in

England over a 6-month period, and resulted in: Increase in referrals for

suspected cancer Increase in number of

colonoscopies Increase in number of

colorectal cancers diagnosed

PRIMARY CARE CANCER DIAGNOSIS RESEARCH

CURRENT Methodological frameworks Public awareness Patient pathways- symptoms Patient views- diagnostics Risk assessment tools

E-clinical decision support Diagnostic technologies

devices, informatics, biomarkers

NEXT… Other behavioural approaches

e.g. patient self-monitoring New investigative & referral

routes Socio-economic inequalities Diagnostic technologies
