Background: Cancers of Unknown Primary (CUP) are the 3-4th most common causes of cancer death and recent clinical guidelines recommend that patients should be directed to a team dedicated to their care. Our aim was to inform the care of patients diagnosed with CUP during hospital admission. Methods: Descriptive study using hospital admissions (Scottish Morbidity Record 01) linked to cancer registrations (ICD-10 C77-80) and death records from 1998 to 2011 in West of Scotland, UK (population 2.4 m). Cox proportional hazards models were used to assess effects of baseline variables on survival. Results: Seven thousand five hundred ninety nine patients were diagnosed with CUP over the study period, 54.4% female, 67.4% aged ≥ 70 years, 36.7% from the most deprived socio-economic quintile. 71% of all diagnoses were made during a hospital admission, among which 88.6% were emergency presentations and the majority (56.3%) were admitted to general medicine. Median length of stay was 15 days and median survival after admission 33 days. Non-specific morphology, emergency admission, age over 60 years, male sex and admission to geriatric medicine were all associated with poorer survival in adjusted analysis. Conclusions: Patients with a diagnosis of CUP are usually diagnosed during unplanned hospital admissions and have very poor survival. To ensure that patients with CUP are quickly identified and directed to optimal care, increased surveillance and rapid referral pathways will be required. © 2017 The Author(s).

Background: We describe changes in prostate cancer incidence, survival and mortality and the resulting impact in additional diagnoses and avoided deaths in European areas and the United States. Methods: Using data from 12 European cancer registries and the Surveillance, Epidemiology and End Results program, we describe changes in prostate cancer epidemiology between the beginning of the PSA era (USA: 1985-1989, Europe: 1990-1994) and 2002-2006 among patients aged 40-64, 65-74, and 75+. Additionally, we examine changes in yearly numbers of diagnoses and deaths and variation in male life expectancy. Results: Incidence and survival, particularly among patients aged <75, increased dramatically, yet both remain (with few exceptions in incidence) lower in Europe than in the United States. Mortality reductions, ongoing since the mid/late 1990s, were more consistent in the United States, had a distressingly small absolute impact among patients aged 40-64 and the largest absolute impact among those aged 75+. Overall ratios of additional diagnoses/avoided deaths varied between 3.6 and 27.6, suggesting large differences in the actual impact of prostate cancer incidence and mortality changes. Ten years of remaining life expectancy was reached between 68 and 76 years. Conclusion: Policies reflecting variation in population life expectancy, testing preferences, decision aids and guidelines for surveillance-based management are urgently needed. © The Author 2011.

Background:Non-melanoma skin cancer has been little studied in relation to deprivation.Methods:Incident cases diagnosed in 1978-2004 were extracted from the Scottish Cancer Register and assigned to quintiles of Carstairs deprivation scores. Age-standardised incidence rates (ASRs) (European standard population) were calculated by deprivation quintile, sex, period of diagnosis, for the three main types of skin cancer.Results and conclusion:As age-standardised incidence of each skin cancer increased significantly over time across all deprivation categories, rates were consistently highest in the least deprived quintile. © 2010 Cancer Research UK All rights reserved.

Objectives: To assess the effect of gender, age and deprivation on key performance indicators in a colorectal cancer screening programme. Setting Between March 2000 and May 2006 a demonstration pilot of biennial guaiac faecal occult blood test (gFOBT) colorectal screening was carried out in North-East Scotland for all individuals aged 50-69 years. Methods: The relevant populations were subdivided, by gender, into four age groups and into five deprivation categories according to the Scottish Index of Multiple Deprivation (SIMD), and key performance indicators analysed within these groups. Results: In all rounds, uptake of the gFOBT increased with age (P < 0.001), decreased with increasing deprivation in both genders (P < 0.001), and was consistently higher in women than in men in all age and all SIMD groups. In addition, increasing deprivation was negatively associated with uptake of colonoscopy in men with a positive gFOBT (P < 0.001) although this effect was not observed in women. Positivity rates increased with age (P < 0.001) and increasing deprivation (P < 0.001) in both genders in all rounds, although they were higher in men than in women for all age and SIMD categories. Cancer detection rates increased with age (P < 0.001), were higher in men than in women in all age and SIMD categories, but were not consistently related to deprivation. In both genders, the positive predictive value (PPV) for cancer increased with age (P < 0.001) and decreased with increasing deprivation (P < 0.001) in all rounds and was consistently higher in men than in women in all age and SIMD categories. Conclusions: In this population-based colorectal screening programme gender, age, and deprivation had marked effects on key performance indicators, and this has implications both for the evaluation of screening programmes and for strategies designed to reduce inequalities.

Background: British 5-year survival from colorectal cancer (CRC) is below the European average, but the reasons are unclear. This study explored if longer provider delays (time from presentation to treatment) were associated with more advanced stage disease at diagnosis and poorer survival.Methods:Data on 958 people with CRC were linked with the Scottish Cancer Registry, the Scottish Death Registry and the acute hospital discharge (SMR01) dataset. Time from first presentation in primary care to first treatment, disease stage at diagnosis and survival time from date of first presentation in primary care were determined. Logistic regression and Cox survival analyses, both with a restricted cubic spline, were used to model stage and survival, respectively, following sequential adjustment of patient and tumour factors.Results:On univariate analysis, those with <4 weeks from first presentation in primary care to treatment had more advanced disease at diagnosis and the poorest prognosis. Treatment delays between 4 and 34 weeks were associated with earlier stage (with the lowest odds ratio occurring at 20 weeks) and better survival (with the lowest hazard ratio occurring at 16 weeks). Provider delays beyond 34 weeks were associated with more advanced disease at diagnosis, but not increased mortality. Following adjustment for patient, tumour factors, emergency admissions and symptoms and signs, no significant relationship between provider delay and stage at diagnosis or survival from CRC was found.Conclusions:Although allowing for a nonlinear relationship and important confounders, moderately long provider delays did not impact adversely on cancer outcomes. Delays are undesirable because they cause anxiety; this may be fuelled by government targets and health campaigns stressing the importance of very prompt cancer diagnosis. Our findings should reassure patients. They suggest that a health service's primary emphasis should be on quality and outcomes rather than on time to treatment. © 2014 Cancer Research UK.

Objectives This study describes changes in the survival of patients with hepatocellular carcinoma (HCC) registered with the Scottish Cancer Registry between 1985 and 2008. Methods Data on patients diagnosed with HCC were extracted from the Scottish Cancer Registry, along with linked data on treatment and risk factors for liver disease. One-, 3- and 5-year relative survival rates were calculated for each time period and a Cox regression model was used to assess the impact of prior admissions on survival. Results The incidence of HCC increased between 1985 and 2008. The proportion of patients with prior alcohol-related admissions rose over the time period studied from 16.0% to 27.1%. Five-year relative survival increased in women between 1985-1989 and 2005-2007 from 0.5% [95% confidence interval (CI) 0.0-3.7] to 10.6% (95% CI 5.2-18.1). In men, 5-year relative survival increased from 0.4% (95% CI 0.2-2.2) to 4.4% (95% CI 1.5-9.9). Regression analysis showed that older age, history of alcohol-related admissions and deprivation were associated with lower survival, and hospitalization for viral hepatitis was associated with higher survival. Conclusions Against the background of an increasing incidence of HCC in Scotland, survival times have increased substantially. © 2012 International Hepato-Pancreato-Biliary Association.

Background: Centralisation of surgical treatment of cancer has resulted in improved outcomes. We aimed to determine evidence of benefit for specialised management of upper gastrointestinal cancer in high-volume centres in Scotland. Methods: Discharge records of patients undergoing oesophagectomy, gastrectomy, hepatectomy or pancreatectomy between 1982 and 2003 were identified. Hospital data were analysed on a year-by-year basis to derive 'hospital-years'. Hospital-years were divided into quartiles by volume, and were analysed with regard to in-hospital mortality during the operative admission [Chi-square test (χ2) and Chi-square test for trend (χ2 trend)]. Results: 10,625 patients and 982 in-hospital deaths were included. In-hospital mortality rates declined during the study period: oesophagectomy 11.7-7.9%; gastrectomy 11.2-7.2%; hepatectomy 11.1-3.0%; and pancreatectomy 8.3-4.9%. For all resections except gastrectomy, mortality decreased as quartile of hospital-year volume increased (oesophagectomy: χ2p = 0.006, χ2 trendp = 0.001; hepatectomy: χ2p = 0.004, χ2 trendp = 0.003; pancreatectomy: χ2p = 0.002, χ2 trendp = 0.001). ORs of death were lower for oesophagectomy (OR = 0.58; 95%CI = 0.39, 0.88; p = 0.009) and pancreatectomy (OR = 0.35; 95%CI = 0.19, 0.64; p < 0.001) in hospital-years within highest-volume quartiles compared with lowest. Scattergraphs of all resection types demonstrated inverse power relationships between number of resections per hospital-year and mortality. Conclusion: Concentration of cancer care has had major effects on health service delivery in Scotland. Centralisation should be supported in surgical management of upper gastrointestinal cancer. © 2009 Elsevier Ltd. All rights reserved.

Objective: To assess the impact of the UK colorectal cancer guaiac faecal occult blood test screening pilot studies on incidence trends, stage distribution and mortality trends. Design: Ecological study. Setting: Scotland and the West Midlands. Data: We extracted anonymised colorectal cancer (ICD-10 C18-C20) registration (1982-2006) and death records (1982-2007), along with corresponding mid-year population estimates. Intervention: Residents of the screening pilot areas, in the age group 50-69 years, were offered biennial guaiac faecal occult blood test screening from 2000 onwards. Screening was not offered routinely in non-pilot areas until the start of the roll-out of the national screening programmes in England and in Scotland in 2006 and 2007, respectively. Main outcome measures: We analysed trends in age-specific incidence and mortality rates, and Dukes' stage distribution. Within each country/region, we compared the screening pilot areas to non-screening pilot ('control') areas using Chi square tests and Poisson regression modelling. Results: Following the start of the screening pilots, as expected in the prevalent round of a new screening programme, in the pilot areas there was a short-lived increase in incidence of colorectal cancer among 50-69 year olds except for females in the West Midlands. A trend towards earlier stage and less advanced disease was also observed, with males showing significant increases in Dukes' A and corresponding decreases in Dukes' C in the screening pilot areas (all P< 0.03). With the exception of females in the West Midlands, mortality rates for colorectal cancer decreased significantly and at a faster rate in the populations invited for screening. Conclusion: The existence of a natural control population not yet invited for screening provided a unique opportunity to assess whether the benefits of colorectal cancer screening, beyond the setting of a randomised controlled trial, could be detected using routinely collected statistics. Our analysis suggests that screening will fulfil its aim of reducing mortality from colorectal cancer. © 2012 Elsevier Ltd.

This study aimed to investigate the effect of metformin on survival of people with type 2 diabetes and pleural mesothelioma.We conducted a retrospective cohort study of people with type 2 diabetes diagnosed with pleural or unspecified mesothelioma between 1993 and 2014 using linked Scottish population-based diabetes and cancer datasets. Kaplan-Meier plots, log-rank tests, and Cox proportional hazards regression models were used to describe the association between use of metformin and all-cause mortality following diagnosis of pleural mesothelioma.There were 300 people with type 2 diabetes and pleural or unspecified mesothelioma of whom 148 had ever used metformin and 290 died during follow up. The median survival time was 8.8 months and 6.5 months for metformin users and non-users respectively (p=0.37, log-rank test). After adjusting for age, sex, diabetes duration, socio-economic status, and other anti-diabetic medications the hazard ratio for mortality associated with metformin was 0.99 (95% confidence intervals: 0.76-1.28; p=0.92). Similar non-statistically significant associations were obtained in sensitivity analyses based on metformin use in year prior to diagnosis of mesothelioma, use of metformin for more than one year, in people below the mean age at diagnosis of mesothelioma (74 years) and 74 years of age or older, limitation to pleural mesothelioma and following further adjustment for body mass index and smoking.There was no evidence that metformin improved survival among people with type 2 diabetes and pleural mesothelioma or to support trials of metformin in people with mesothelioma.

Background: There is emerging evidence to suggest that the association between socioeconomic circumstances and colorectal cancer incidence has changed over recent decades.Methods: We conducted a descriptive population-based study to describe the relationship between socioeconomic circumstances and the incidence of colorectal cancer in a pre-screened population. Incident cases of colorectal cancer from the West of Scotland were identified from the Scottish Cancer Registry and European age-standardised incidence rates (EASR) were calculated. Socioeconomic circumstances were measured using the area-based Scottish Index of Multiple Deprivation (SIMD). Results: In total, 14 051 incident cases of colorectal cancer were recorded from 1999 to 2007. Incidence of colorectal cancer was associated with increased deprivation in men but not among women; an association that became evident from 2005 onwards. From 2005 to 2007, the deprivation gap in incidence among men was 13.3 per 100 000 (95% confidence interval 3.2-23.4), with rates 19.5% lower among the least deprived compared with the most deprived. This deprivation gap now accounts for an estimated 75 excess cases per year of male colorectal cancer in the West of Scotland. Conclusion: Deprivation was associated with higher incidence rates of male, but not female, colorectal cancer before the implementation of a national bowel screening programme. © 2011 Cancer Research UK All rights reserved.
