1. 11. Data quality in the National Prostate Cancer Register (NPCR) of Sweden

   Författare :Katarina Tomic; Pär Stattin; Mats Lambe; Christel Häggström; Helgi Birgisson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; Cancer quality register; Data quality; Evaluation; Validity;

   Sammanfattning : Background: Data in quality registers are increasingly used for quality assurance of health care, benchmarking, and research. If valid conclusions are to be drawn from such studies, it is vital that register data have high quality. LÄS MER

3. 12. How to model temporal changes in epidemiological data : Treatment trajectories in men with prostate cancer

   Författare :Eugenio Ventimiglia; Pär Stattin; Paul C. Lambert; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; state transition model; life expectancy; active surveillance; watchful waiting;

   Sammanfattning : Owing to the improvements in detection, diagnostics, and treatment, many men currently diagnosed with prostate cancer (PCa) have a low risk of PCa death. For many men PCa has become a chronic disease with a small risk of progression that remains even decades after date of diag-nosis. LÄS MER

4. 13. Modelling short and long term consequences of changes in diagnostic activity and treatment

   Författare :Marcus Westerberg; Rolf Larsson; Hans Garmo; Pär Stattin; Keith Humphreys; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mathematics prostate cancer statistics diagnostic activity; Statistics; Statistik; Epidemiologi; Epidemiology; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

   Sammanfattning : Since the late 90’s the diagnostic activity for prostate cancer has increased in Sweden, primarily due to increased use of PSA testing, and this has led to a large increase in diagnoses. Simultaneously, there have been changes in treatment strategies, and more effective treatments have been introduced. LÄS MER

5. 14. Prostate cancer incidence, treatment and mortality : Empirical longitudinal register-based studies and methods for handling missing data

   Författare :Marcus Westerberg; Rolf Larsson; Hans Garmo; Pär Stattin; Jimmy Olsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistics; mathematics; prostate cancer; missing data; survival analysis; longitudinal models; incidence; treatment; mortality; Mathematical Statistics; Matematisk statistik; Statistics; Statistik; Urologi; Urology; Epidemiologi; Epidemiology;

   Sammanfattning : The diagnostic activity for prostate cancer has increased substantially in Sweden, primarily due to increased use of prostate-specific antigen (PSA) testing in asymptomatic men, and this has led to a large increase in diagnoses. There have also been changes in the diagnostic workup, guidelines, treatment strategies, and more effective treatments have been introduced in different phases of the disease. LÄS MER

7. 15. Prospective studies of hormonal and life-style related factors and risk of cancer

   Författare :Sara Wirén; Pär Stattin; Håkan Jonsson; Tanja Stocks; Alicja Wolk; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; epidemiology; androgens; risk factors; fatherhood status; dizygotic twins; height; cohort; case-control; prospective; Cancer Epidemiology; cancerepidemiologi;

   Sammanfattning : Background: Androgens are important in prostate cancer development but how circulating levels of androgens affect risk of prostate cancer of different aggressiveness is not clear. Being childless has been associated with a lower risk of prostate cancer, but it is not clear if this association is causal or a result of residual confounding. LÄS MER
