This study evaluates the adherence to clinical practice guidelines (CPGs) and patient outcomes in rectal cancer, with a particular focus on variation according to age. This is a multicentre retrospective cohort study of all patients surgically treated for the first time for primary rectal cancer with curative intent in public hospitals in Catalonia during two study periods: first, with data from 2005 to 2007, and then with data from 2011 to 2012. We obtained the study data through a comprehensive review of patients' clinical records. Information on diagnosis, treatment and follow-up was collected and then compared with the relevant CPGs. We then performed a descriptive analysis of the categorical variables followed by a univariate and multivariate logistic regression analysis to calculate the odds ratio. Finally, we calculated the recurrence and death rates per person-year at 2 years' follow-up. ...

We used data from the Cornella Health Interview Survey Follow-up Study (n = 2,500). We included for the analysis those subjects who declared to be daily smokers at baseline (1994) and continued smoking after eight years of follow-up (n = 234). We considered as operational definition of reduction to reduce > or = 10 cigarettes/day. We calculated the relative risk (RR) of smoking reduction vs. maintain or increase tobacco consumption and 95% confidence intervals (CI) by means of a Breslow-Cox regression model. The average reduction on number of cigarettes among subjects who reduced their tobacco consumption was similar in men and women (13 cigarettes/day). The consumption intensity and self-perceived health are the characteristics associated with reduction: smoking reduction was associated with being a smoker > 20 cigarettes/day (RR = 3.25; 95...

Data were obtained from Tarragona and Girona cancer registries and Catalan mortality registry. Population age distribution was obtained from the Catalan Institute of Statistics. Predicted cases in Catalonia were estimated through autoregressive Bayesian age-period-cohort models. There will be diagnosed 26,455 incident cases among men and 18,345 among women during 2020, which means an increase of 22.5 and 24.5 % comparing with the cancer incidence figures of 2010. In men, the increase of cases (22.5 %) can be partitioned in three components: 12 % due to ageing, 8 % due to increase in population size and 2 % due to cancer risk. In women, the role of each component was 9, 8 and 8 %, respectively. The increased risk is mainly expected to be observed in tobacco-related tumours among women and in colorectal and liver cancers among men. During 2010-2020 a mortality decline is expected in both sexes. The expected increase of cancer incidence, mainly due to tobacco-related tumours in women and colorectal in men, reinforces the need to strengthen smoking prevention and the expansion of early detection of colorectal cancer in Catalonia.

Predictive discrimination of both risk assessments (surgeons' and model) was compared through the area under the receiver operating characteristic curve. Logistic regression analysis was used to assess the relation between surgeons' and model predictions to actual outcomes. Calibration of the subjective estimates was evaluated with a chi2 test. Overall, the area under the receiver operating characteristic curve was 0.76 for the statistical model and 0.70 for the subjective assessment. Logistic regression analysis showed that the statistical model remained significant after accounting for the subjective assessment. Calibration of subjective mortality predictions was poor. Surgeons' risk assessment tends to cluster in the middle ranges of risk. Subjective assessment seems accurate in identifying the two extremes of risk but is inaccurate for intermediate risk levels. A multivariate statistical model improves the accuracy of subjective predictions.
