- Background: There is insufficient information regarding the benefit of treatment with curative intent for men with localised poorly differentiated prostate cancer (PCa). Objective: To evaluate relative survival in men with potentially curable PCa in relation to Gleason score (GS) and treatment as practiced in the community at large. Design, setting, and participants: A population-based study including all men with localised PCa registered in Sweden's National Prostate Cancer Register. Interventions: Hormonal therapy, watchful waiting, and treatment with curative intent. Measurements: The ratio of observed deaths to expected deaths, determined from survival in the general male population of the same age, was assessed using Poisson regression analysis, with GS and treatment as covariates. Interaction between GS and treatment was tested in a multivariate Cox proportional hazard analysis. Results and limitations: A total of 31 903 men with potentially curable tumour (T1-T3, N0/NX, M0/MX, age < 75 yr, and prostate-specific antigen [PSA] < 20 ng/ml) were identified. GS was recorded for 28 454 of these men. Some 19 606 men (60.8%) were treated with curative intent, and 12 645 men (39.2%) were given either hormonal treatment or expectant management. The ratios between observed and expected survival gradually increased for men with GS 10, with GS to 3.3 for men treated conservatively and to 1.4 for men treated with curative intent. There was a significant interaction between GS and treatment, with a relatively greater benefit from treatment with curative intent for men with high-grade tumours. The results have to be interpreted with some caution, as there was no randomisation between the treatment groups. Conclusions: Survival for men with well-differentiated tumours is close to that of the general population, regardless of treatment, but the outcome is dismal for men with poorly differentiated tumours, whichever treatment is applied. Nevertheless, men with poorly differentiated tumours benefit more from curative treatment than do men with well-differentiated tumours.

- Objective To assess whether screening for prostate cancer reduces prostate cancer specific mortality. Design Population based randomised controlled trial. Setting Department of Urology, Norrkoping, and the South-East Region Prostate Cancer Register. Participants All men aged 50-69 in the city of Norrkoping, Sweden, identified in 1987 in the National Population Register (n=9026). Intervention From the study population, 1494 men were randomly allocated to be screened by including every sixth man from a list of dates of birth. These men were invited to be screened every third year from 1987 to 1996. On the first two occasions screening was done by digital rectal examination only. From 1993, this was combined with prostate specific antigen testing, with 4 mu g/L as cut off. On the fourth occasion (1996), only men aged 69 or under at the time of the investigation were invited. Main outcome measures Data on tumour stage, grade, and treatment from the South East Region Prostate Cancer Register. Prostate cancer specific mortality up to 31 December 2008. Results In the four screenings from 1987 to 1996 attendance was 1161/1492 (78%), 957/1363 (70%), 895/1210 (74%), and 446/606 (74%), respectively. There were 85 cases (5.7%) of prostate cancer diagnosed in the screened group and 292 (3.9%) in the control group. The risk ratio for death from prostate cancer in the screening group was 1.16 (95% confidence interval 0.78 to 1.73). In a Cox proportional hazard analysis comparing prostate cancer specific survival in the control group with that in the screened group, the hazard ratio for death from prostate cancer was 1.23 (0.94 to 1.62; P=0.13). After adjustment for age at start of the study, the hazard ratio was 1.58 (1.06 to 2.36; P=0.024). Conclusions After 20 years of follow-up the rate of death from prostate cancer did not differ significantly between men in the screening group and those in the control group.
