BackgroundColorectal cancer (CRC) is an illness strongly influenced by sex and gender, with mortality rates in males significantly higher than females. There is still a dearth of understanding on where sex differences exist along the pathway from presentation to survival. The aim of this review is to identify where actions are needed to improve outcomes for both sexes, and to narrow the gap for CRC.MethodsA cross-sectional review of national data was undertaken to identify sex differences in incidence, screening uptake, route to diagnosis, cancer stage at diagnosis and survival, and their influence in the sex differences in mortality.ResultsOverall incidence is higher in men, with an earlier age distribution, however, important sex differences exist in anatomical site. There were relatively small differences in screening uptake, route to diagnosis, cancer staging at diagnosis and survival. Screening uptake is higher in women under 69 years. Women are more likely to present as emergency cases, with more men diagnosed through screening and two-week-wait. No sex differences are seen in diagnosis for more advanced disease. Overall, age-standardised 5-year survival is similar between the sexes.ConclusionsAs there are minimal sex differences in the data from routes to diagnosis to survival, the higher mortality of colorectal cancer in men appears to be a result of exogenous and/or endogenous factors pre-diagnosis that lead to higher incidence rates. There are however, sex and gender differences that suggest more targeted interventions may facilitate prevention and earlier diagnosis in both men and women.

Introduction:Long-term lung cancer survival in England has improved little in recent years and is worse than many countries. The Department of Health funded a campaign to raise public awareness of persistent cough as a lung cancer symptom and encourage people with the symptom to visit their GP. This was piloted regionally within England before a nationwide rollout.Methods:To evaluate the campaign's impact, data were analysed for various metrics covering public awareness of symptoms and process measures, through to diagnosis, staging, treatment and 1-year survival (available for regional pilot only).Results:Compared with the same time in the previous year, there were significant increases in metrics including: public awareness of persistent cough as a lung cancer symptom; urgent GP referrals for suspected lung cancer; and lung cancers diagnosed. Most encouragingly, there was a 3.1 percentage point increase (P<0.001) in proportion of non-small cell lung cancer diagnosed at stage I and a 2.3 percentage point increase (P<0.001) in resections for patients seen during the national campaign, with no evidence these proportions changed during the control period (P=0.404, 0.425).Conclusions:To our knowledge, the data are the first to suggest a shift in stage distribution following an awareness campaign for lung cancer. It is possible a sustained increase in resections may lead to improved long-term survival.

Background:National campaigns focusing on key symptoms of bowel and lung cancer ran in England in 2012, targeting men and women over the age of 50 years, from lower socioeconomic groups.Methods:Data from awareness surveys undertaken with samples of the target audience (n=1245/1140 pre-/post-bowel campaign and n=1412/1246 pre-/post-lung campaign) and Read-code data extracted from a selection general practitioner (GP) practices (n=355 for bowel and n=486 for lung) were analysed by population subgroups.Results:Unprompted symptom awareness: There were no significant differences in the magnitude of shift in ABC1 vs C2DE groups for either campaign. For the bowel campaign, there was a significantly greater increase in awareness of blood in stools in the age group 75+ years compared with the 55–74 age group, and of looser stools in men compared with women. Prompted symptom awareness: Endorsement of ‘blood in poo' remained stable, overall and across different population subgroups. Men showed a significantly greater increase in endorsement of ‘looser poo' as a definite warning sign of bowel cancer than women. There were no significant differences across subgroups in endorsement of a 3-week cough as a definite warning sign of lung cancer. GP attendances: Overall, there were significant increases in attendances for symptoms directly linked to the campaigns, with the largest percentage increase seen in the 50–59 age group. For the bowel campaign, the increase was significantly greater for men and for practices in the most-deprived quintile, whereas for lung the increase was significantly greater for practices in the least-deprived quintile.Conclusions:The national bowel and lung campaigns reached their target audience and have also influenced younger and more affluent groups. Differences in impact within the target audience were also seen. There would seem to be no unduly concerning widening in inequalities, but further analyses of the equality of impact across population subgroups is warranted.

Background:Although inequalities in cancer survival are thought to reflect inequalities in stage at diagnosis, little evidence exists about the size of potential survival gains from eliminating inequalities in stage at diagnosis.Methods:We used data on patients diagnosed with malignant melanoma in the East of England (2006–2010) to estimate the number of deaths that could be postponed by completely eliminating socioeconomic and sex differences in stage at diagnosis after fitting a flexible parametric excess mortality model.Results:Stage was a strong predictor of survival. There were pronounced socioeconomic and sex inequalities in the proportion of patients diagnosed at stages III–IV (12 and 8% for least deprived men and women and 25 and 18% for most deprived men and women, respectively). For an annual cohort of 1025 incident cases in the East of England, eliminating sex and deprivation differences in stage at diagnosis would postpone approximately 24 deaths to beyond 5 years from diagnosis. Using appropriate weighting, the equivalent estimate for England would be around 215 deaths, representing 11% of all deaths observed within 5 years from diagnosis in this population.Conclusions:Reducing socioeconomic and sex inequalities in stage at diagnosis would result in substantial reductions in deaths within 5 years of a melanoma diagnosis.

HighlightsOn average, people endorsed three barriers that would put them off seeing a GP.Women, younger people and more deprived groups were more likely to endorse barriers.Service-related barriers endorsed more than barriers related to GP–patient relations.Endorsement of not wanting to be seen making a fuss reveals more social element.The results suggest that there may be additional barriers influencing patient behaviour.

Background Lung cancer is the leading cause of cancer mortality in Wales. We conducted a before-and afterstudy to evaluate the impact of a four-week mass media campaign on awareness, presentation behaviour and lung cancer outcomes. Methods Population-representative samples were surveyed for cough symptom recall/recognition and worry about wasting doctors' time pre-campaign (June 2016; n=1,001) and post-campaign (September 2016; n=1,013). GP cough symptom visits, urgent suspected cancer (USC) referrals, GP-ordered radiology, new lung cancer diagnoses and stage at diagnosis were compared using routine data during the campaign (July-August 2016) and corresponding control (July-August 2015) periods. Results Increased cough symptom recall (p<0.001), recognition (p<0.001) and decreased worry (p<0.001) were observed. GP visits for cough increased by 29% in the target 50+ age-group during the campaign (p<0.001) and GP-ordered chest X-rays increased by 23% (p<0.001). There was no statistically significant change in USC referrals (p=0.82), new (p=0.70) or early stage (p=0.27) diagnoses, or in routes to diagnosis. Conclusion Symptom awareness, presentation and GP-ordered chest x-rays increased during the campaign, but did not translate into increased USC referrals or clinical outcomes changes. Short campaign duration and follow up, and the small number of new lung cancer cases observed may have hampered detection effects.
