Background The reported incidence of Philadelphia-negative myeloproliferative neoplasms (MPNs) differs substantially between previous reports, likely due to true regional differences in incidence and/or variations in the quality and coverage of the cancer registers. Objective We therefore assessed MPN incidence in Sweden during recent years using prospectively collected information captured in Swedish health registers. Methods Patients with MPNs were identified through the Swedish Cancer Register and Swedish Blood Cancer Register between 2000 and 2014. Information on the Swedish population was obtained from the Human Mortality Database. Crude and age-standardized incidence rates of MPNs with 95% confidence intervals (CIs) were calculated. Results A total of 6281 MPN cases were reported to the Swedish Cancer Register and Swedish Blood Cancer Register during 2000-2014. The age-standardized, to the Swedish population in 2000, incidence for all MPNs was 4.45 (95% confidence interval [CI] 4.34-4.56)/100 000 person-years. The age-standardized incidence for polycythemia vera was 1.48 (1.42-1.54), for essential thrombocythemia 1.60 (1.53-1.66) and for primary myelofibrosis 0.52 (0.48-0.56)/100 000 person-years, respectively. The incidence rate of MPNs was substantially higher in the older compared to the younger age groups. The incidence increased during the study period, likely to do better reporting and increasing age of the general population. Conclusion The reported MPN incidences in our study, which were in the higher interval of previously published studies, are likely more accurate compared to previous reports due to the population-based setting and high level of coverage in the Swedish Cancer and Blood Cancer Registers., Funding Agencies|Karolinska InstitutetKarolinska Institutet; NCI NIH HHSUnited States Department of Health & Human ServicesNational Institutes of Health (NIH) - USANIH National Cancer Institute (NCI) [P30 CA008748, P30 CA008748]; Stockholm County CouncilStockholm County Council; Swedish Research CouncilSwedish Research Council; Blodcancerfonden; Cancer Research Foundations of Radiumhemmet

Several individual components of the Mediterranean diet have been shown to offer protection against prostate cancer. The present study is the first to investigate the association between adherence to the Mediterranean diet and the relative risk of prostate cancer. We also explored the usefulness of the Mediterranean Diet Score (MDS) in a non-Mediterranean population. FFQ data were obtained from 1482 incident prostate cancer patients and 1108 population- based controls in the Cancer of the Prostate in Sweden (CAPS) study. We defined five MDS variants with different components or using either study-specific intakes or intakes in a Greek reference population as cut-off values between low and high intake of each component. Unconditional logistic regression was used to estimate the relative risk of prostate cancer for high and medium v. low MDS, as well as potential associations with the individual score components. No statistically significant association was found between adherence to the Mediterranean diet based on any of the MDS variants and prostate cancer risk (OR range: 0·96-1·19 for total prostate cancer, comparing high with low adherence). Overall, we found little support for an association between the Mediterranean diet and prostate cancer in this Northern European study population. Despite potential limitations inherent in the study or in the build-up of a dietary score, we suggest that the original MDS with study-specific median intakes as cut-off values between low and high intake is useful in assessing the adherence to the Mediterranean diet in non-Mediterranean populations.

Aim of study Differences in the survival of colon cancer patients by socioeconomic status have been demonstrated in several populations but the underlying reasons for the differences are not well understood By simultaneously estimating the proportion of patients cured from colon cancer and the survival times of the uncured we hope to increase under standing of how socioeconomic status affects survival following a diagnosis of colon cancer Methods We conducted a population based cohort study of 58 873 patients diagnosed with colon cancer in Sweden 1965-2000 Socioeconomic status was classified based on occupation We fitted mixture cure models and Poisson regression models adjusted for age sex and calendar period Results We observed higher excess mortality lower proportion cured and shorter survival times among the uncured in patients from lower socioeconomic groups compared to the highest socioeconomic group There was no evidence that the gap between the socioeconomic groups reduced over time Farmers had the lowest odds of cure (odds ratio (OR) 0 85 95% confidence interval (Cl) 0 75-0 95) compared to higher non manual workers followed by self employed (0 91, 0 81-1 03) manual workers (0 93, 0 85-1 03) and lower non manual workers (0 91 0 89-1 08) Conclusion Patients from lower socioeconomic groups in Sweden experience worse survival following a diagnosis of colon cancer Differences exist in both the cure proportion and the survival time of the uncured suggesting that socioeconomic differences cannot be attributed solely to lead time bias Although this study has furthered our under standing of socioeconomic differences in survival more detailed studies are required in order to identify and subsequently remove the underlying reasons for the differences.
