  • Time without PSA recurrence after radical prostatectomy as a predictor of future biochemical recurrence, metastatic disease and prostate cancer death : a prospective Scandinavian cohort study
  • 2022
  • Ingår i: BMJ Open. - : BMJ Publishing Group Ltd. - 2044-6055. ; 12:12
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: Although surveillance after radical prostatectomy routinely includes repeated prostate specific antigen (PSA)-testing for many years, biochemical recurrence often occurs without further clinical progression. We therefore hypothesised that follow-up can be shortened for many patients without increasing the risk of prostate cancer death. We investigated the long-term probabilities of PSA recurrence, metastases and prostate cancer death in patients without biochemical recurrence five and 10 years after radical prostatectomy.Design: Prospective cohort study. Stratification by Gleason score (<= 3+4=7or >= 4+3=7), pathological tumour stage (pT2 or >= pT3) and negative or positive surgical margins.Setting: Between 1989 and 1998, 14 urological centres in Scandinavia randomised patients to the Scandinavian Prostate Cancer Group study number 4 (SPCG-4) trial.ParticipationAll 306 patients from the SPCG-4 trial who underwent radical prostatectomy within 1year from inclusion were eligible. Four patients were excluded due to surgery-related death (n=1) or salvage radiotherapy or hormonal treatment within 6weeks from surgery (n=3).Primary outcome measures: Cumulative incidences and absolute differences in metastatic disease and prostate cancer death.Results: We analysed 302 patients with complete follow-up during a median of 24 years. Median preoperative PSA was 9.8ng/mL and median age was 65 years. For patients without biochemical recurrence 5 years after radical prostatectomy the 20-year probability of biochemical recurrence was 25% among men with Gleason score <= 3+4=7and 57% among men with Gleason score >= 4+3=7; the probabilities for metastases were 0.8% and 17%; and for prostate cancer death 0.8% and 12%, respectively. The long-term probabilities were higher for pT >= 3versus pT2 and for positive versus negative surgical margins. Limitations include small size of the cohort.Conclusion: Many patients with favourable histopathology without biochemical recurrence 5years after radical prostatectomy could stop follow-up earlier than 10 years after radical prostatectomy.

  • Managing localized prostate cancer by radical prostatectomy or watchful waiting: Cost analysis of a randomized trial (SPCG-4)
  • 2011
  • Ingår i: SCANDINAVIAN JOURNAL OF UROLOGY AND NEPHROLOGY. - : Informa Healthcare. - 0036-5599 .- 1651-2065. ; 45:3, s. 177-183
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. The cost of radical prostatectomy (RP) compared to watchful waiting (WW) has never been estimated in a randomized trial. The goal of this study was to estimate long-term total costs per patient associated with RP and WW arising from inpatient and outpatient hospital care. Material and methods. This investigation used the Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4) trial, comparing RP to WW, and included data from 212 participants living in two counties in Sweden from 1989 to 1999 (105 randomized to WW and 107 to RP). All costs were included from randomization date until death or end of follow-up in July 2007. Resource use arising from inpatient and outpatient hospital costs was measured in physical units and multiplied by a unit cost to come up with a total cost per patient. Results. During a median follow-up of 12 years, the overall cost in the RP group was 34% higher (p andlt; 0.01) than in the WW group, corresponding to euroa,not sign6123 in Sweden. The difference was driven almost exclusively by the cost of the surgical procedure. The cost difference between RP and WW was two times higher among men with low (2--6) than among those with high (7--10) Gleason score. Conclusion. In this economic evaluation of RP versus WW of localized prostate cancer in a randomized study, RP was associated with 34% higher costs. This difference, attributed exclusively to the cost of the RP procedure, was not overcome during extended follow-up.

  • Radical Prostatectomy or Watchful Waiting in Early Prostate Cancer
  • 2014
  • Ingår i: New England Journal of Medicine. - Waltham : Massachusetts Medical Society. - 0028-4793 .- 1533-4406. ; 370:10, s. 932-942

    • BackgroundRadical prostatectomy reduces mortality among men with localized prostate cancer; however, important questions regarding long-term benefit remain. MethodsBetween 1989 and 1999, we randomly assigned 695 men with early prostate cancer to watchful waiting or radical prostatectomy and followed them through the end of 2012. The primary end points in the Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4) were death from any cause, death from prostate cancer, and the risk of metastases. Secondary end points included the initiation of androgen-deprivation therapy. ResultsDuring 23.2 years of follow-up, 200 of 347 men in the surgery group and 247 of the 348 men in the watchful-waiting group died. Of the deaths, 63 in the surgery group and 99 in the watchful-waiting group were due to prostate cancer; the relative risk was 0.56 (95% confidence interval [CI], 0.41 to 0.77; P=0.001), and the absolute difference was 11.0 percentage points (95% CI, 4.5 to 17.5). The number needed to treat to prevent one death was 8. One man died after surgery in the radical-prostatectomy group. Androgen-deprivation therapy was used in fewer patients who underwent prostatectomy (a difference of 25.0 percentage points; 95% CI, 17.7 to 32.3). The benefit of surgery with respect to death from prostate cancer was largest in men younger than 65 years of age (relative risk, 0.45) and in those with intermediate-risk prostate cancer (relative risk, 0.38). However, radical prostatectomy was associated with a reduced risk of metastases among older men (relative risk, 0.68; P=0.04). ConclusionsExtended follow-up confirmed a substantial reduction in mortality after radical prostatectomy; the number needed to treat to prevent one death continued to decrease when the treatment was modified according to age at diagnosis and tumor risk. A large proportion of long-term survivors in the watchful-waiting group have not required any palliative treatment. (Funded by the Swedish Cancer Society and others.) The randomized Swedish trial of prostatectomy versus watchful waiting in disease detected mainly clinically (not by PSA screening) continues to show a benefit for early prostatectomy. The number of men younger than 65 needed to treat to prevent one death is now four. The Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4), a randomized trial of radical prostatectomy versus watchful waiting in men with localized prostate cancer diagnosed before the era of prostate-specific antigen (PSA) testing, showed a survival benefit of radical prostatectomy as compared with observation at 15 years of follow-up.(1) By contrast, the Prostate Cancer Intervention versus Observation Trial (PIVOT), initiated in the early era of PSA testing, showed that radical prostatectomy did not significantly reduce prostate cancer-specific or overall mortality after 12 years.(2) PSA screening profoundly changes the clinical domain of study. Among other considerations, the substantial additional lead time ...

  • Immediate risk for cardiovascular events and suicide following a prostate cancer diagnosis : prospective cohort study
  • 2009
  • Ingår i: PLoS Medicine. - San Francisco, Calif. : Public Library of Science. - 1549-1277 .- 1549-1676. ; 6:12, s. e1000197-
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Stressful life events have been shown to be associated with altered risk of various health consequences. The aim of the present study was to investigate whether the emotional stress evoked by a prostate cancer diagnosis increases the immediate risks of cardiovascular events and suicide.METHODS AND FINDINGS: We conducted a prospective cohort study by following all men in Sweden who were 30 y or older (n = 4,305,358) for a diagnosis of prostate cancer (n = 168,584) and their subsequent occurrence of cardiovascular events and suicide between January 1, 1961 and December 31, 2004. We used Poisson regression models to calculate relative risks (RRs) and 95% confidence intervals (CIs) of cardiovascular events and suicide among men who had prostate cancer diagnosed within 1 y to men without any cancer diagnosis. The risks of cardiovascular events and suicide were elevated during the first year after prostate cancer diagnosis, particularly during the first week. Before 1987, the RR of fatal cardiovascular events was 11.2 (95% CI 10.4-12.1) during the first week and 1.9 (95% CI 1.9-2.0) during the first year after diagnosis. From 1987, the RR for cardiovascular events, nonfatal and fatal combined, was 2.8 (95% CI 2.5-3.2) during the first week and 1.3 (95% CI 1.3-1.3) during the first year after diagnosis. While the RR of cardiovascular events declined, the RR of suicide was stable over the entire study period: 8.4 (95% CI 1.9-22.7) during the first week and 2.6 (95% CI 2.1-3.0) during the first year after diagnosis. Men 54 y or younger at cancer diagnosis demonstrated the highest RRs of both cardiovascular events and suicide. A limitation of the present study is the lack of tumor stage data, which precluded possibilities of investigating the potential impact of the disease severity on the relationship between a recent diagnosis of prostate cancer and the risks of cardiovascular events and suicide. In addition, we cannot exclude residual confounding as a possible explanation.CONCLUSIONS: Men newly diagnosed with prostate cancer are at increased risks for cardiovascular events and suicide. Future studies with detailed disease characteristic data are warranted.

  • Prostate-specific antigen levels as a predictor of lethal prostate cancer
  • 2007
  • Ingår i: Journal of the National Cancer Institute. - Oxford : Oxford Univ. Press. - 0027-8874 .- 1460-2105. ; 99:7, s. 526-532
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Rates of long-term survival among patients with untreated localized prostate cancer are high. To avoid unnecessary treatment, tools are needed to identify the small proportion of patients who are destined to develop lethal prostate cancer. Methods: To evaluate the accuracy of early changes in prostate-specific antigen (PSA) levels as predictors of prostate cancer outcome, we assessed serial measurements of PSA level among 267 men with localized prostate cancer in a Scandinavian cohort of men who were diagnosed between 1989 and 1999 and who were managed by watchful waiting. We then 1) fitted individual regression lines to the PSA values assessed for each patient during the first 2 years of follow-up by using three different models, 2) evaluated early PSA curve characteristics as determinants of the cumulative incidence of lethal prostate cancer and calculated hazard ratios for baseline PSA value and rate of change in PSA level to prostate cancer outcome, and 3) plotted time-dependent receiver operating characteristic (ROC) curves. All P values are two-sided. Results: During complete follow-up for a mean of 8.5 years, 34 patients (13%) died from prostate cancer, and 18 (7%) developed metastases but were still alive at end of follow-up. In a log-linear model, both PSA value at baseline (P = .05) and the rate of PSA change (P<.001) were associated with the development of lethal prostate cancer. In the ROC analysis, however, the accuracy of classifying the disease as either indolent or destined to progress was low, regardless of the cut point chosen for initial PSA level or rate of change in PSA level. Conclusions: Although baseline PSA value and rate of PSA change are prognostic factors for lethal prostate cancer, they are poor predictors of lethal prostate cancer among patients with localized prostate cancer who are managed by watchful waiting.

  • Natural history of early, localized prostate cancer
  • 2004
  • Ingår i: Journal of the American Medical Association (JAMA). - : American Medical Association (AMA). - 0098-7484 .- 1538-3598. ; 291:22, s. 2713-2719
  • Tidskriftsartikel (refereegranskat)abstract
    • CONTEXT: Among men with early prostate cancer, the natural history without initial therapy determines the potential for survival benefit following radical local treatment. However, little is known about disease progression and mortality beyond 10 to 15 years of watchful waiting. OBJECTIVE: To examine the long-term natural history of untreated, early stage prostatic cancer. DESIGN: Population-based, cohort study with a mean observation period of 21 years. SETTING: Regionally well-defined catchment area in central Sweden (recruitment March 1977 through February 1984). PATIENTS: A consecutive sample of 223 patients (98% of all eligible) with early-stage (T0-T2 NX M0 classification), initially untreated prostatic cancer. Patients with tumor progression were hormonally treated (either by orchiectomy or estrogens) if they had symptoms. MAIN OUTCOME MEASURES: Progression-free, cause-specific, and overall survival. RESULTS: After complete follow-up, 39 (17%) of all patients experienced generalized disease. Most cancers had an indolent course during the first 10 to 15 years. However, further follow-up from 15 (when 49 patients were still alive) to 20 years revealed a substantial decrease in cumulative progression-free survival (from 45.0% to 36.0%), survival without metastases (from 76.9% to 51.2%), and prostate cancer-specific survival (from 78.7% to 54.4%). The prostate cancer mortality rate increased from 15 per 1000 person-years (95% confidence interval, 10-21) during the first 15 years to 44 per 1000 person-years (95% confidence interval, 22-88) beyond 15 years of follow-up (P =.01). CONCLUSION: Although most prostate cancers diagnosed at an early stage have an indolent course, local tumor progression and aggressive metastatic disease may develop in the long term. These findings would support early radical treatment, notably among patients with an estimated life expectancy exceeding 15 years.

  • Homogeneous prostate cancer mortality in the Nordic countries over four decades
  • 2010
  • Ingår i: European Urology. - : Elsevier. - 0302-2838 .- 1873-7560. ; 58:3, s. 427-32
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Incidence of prostate cancer (PCa) has greatly increased in the Nordic region over the past two decades, following the advent of prostate-specific antigen (PSA) screening. Consequently, interpreting temporal trends in PCa has become difficult, and the impact of changes in exposure to causal factors is uncertain.OBJECTIVE: To reveal geographic differences and temporal trends in PCa in the Nordic countries. Because the recorded incidence of PCa has been profoundly influenced by PSA screening, we focused our analyses primarily on PCa mortality.DESIGN, SETTING, AND PARTICIPANTS: We analyzed national PCa incidence and mortality data from Denmark, Finland, Norway, and Sweden from 1965 to 2006 using the PC-NORDCAN software program and the online NORDCAN database.MEASUREMENTS: Cumulative incidence and cumulative mortality from PCa were calculated for selected calendar years during four decades, along with age-standardized mortality rates. Incidence data in NORDCAN come from individual countries' cancer registries, and mortality data come from national mortality registries.RESULTS AND LIMITATIONS: From 1965 to 2006, 172 613 deaths from PCa were reported in the four Nordic countries. A substantial rise in incidence was observed across the region, with some geographic variation, since the late 1980s. In contrast, both disease-specific mortality rates and cumulative risk of PCa mortality lacked consistent temporal trends over the same period. Cumulative mortality from PCa ranged between 3.5% and 7.5% in the region over four decades, whereas cumulative incidence jumped from about 9% to >20%. Mortality has remained fairly constant among the countries, with a minimally lower risk in Finland.CONCLUSIONS: Unlike most malignancies, the occurrence of lethal PCa showed minimal geographic variation and lacked consistent temporal trends over four decades. These findings may guide our search for important causes of PCa, a malignancy with etiology that is still largely unknown.

  • Nine-gene molecular signature is not associated with prostate cancer death in a watchful waiting cohort
  • 2008
  • Ingår i: Cancer Epidemiology, Biomarkers and Prevention. - Baltimore : Waverly Press. - 1055-9965 .- 1538-7755. ; 17:1, s. 249-251
  • Tidskriftsartikel (refereegranskat)abstract
    • Tumor molecular markers hold promise to distinguish potentially lethal from indolent prostate cancer and to guide treatment choices. A previous study identified a nine-gene molecular signature in tumors associated with prostate-specific antigen relapse after prostatectomy. We examined this molecular model in relation to prostate cancer death among 172 men with initially localized disease. We quantified protein expression of the nine genes in tumors to classify progression risk. Accounting for clinical prognostic factors, the nine-gene model did not provide discrimination to predict lethal and indolent prostate cancer.

  • Testing a multigene signature of prostate cancer death in the Swedish Watchful Waiting Cohort
  • 2008
  • Ingår i: Cancer Epidemiology, Biomarkers and Prevention. - Philadelphia : American Association for Cancer Research. - 1055-9965 .- 1538-7755. ; 17:7, s. 1682-1688
  • Tidskriftsartikel (refereegranskat)abstract
    • Although prostate cancer is a leading cause of cancer death, most men die with and not from their disease, underscoring the urgency to distinguish potentially lethal from indolent prostate cancer. We tested the prognostic value of a previously identified multigene signature of prostate cancer progression to predict cancer-specific death. The Örebro Watchful Waiting Cohort included 172 men with localized prostate cancer of whom 40 died of prostate cancer. We quantified protein expression of the markers in tumor tissue by immunohistochemistry and stratified the cohort by quintiles according to risk classification. We accounted for clinical variables (age, Gleason, nuclear grade, and tumor volume) using Cox regression and calculated receiver operator curves to compare discriminatory ability. The hazard ratio of prostate cancer death increased with increasing risk classification by the multigene model, with a 16-fold greater risk comparing highest-risk versus lowest-risk strata, and predicted outcome independent of clinical factors (P = 0.002). The best discrimination came from combining information from the multigene markers and clinical data, which perfectly classified the lowest-risk stratum where no one developed lethal disease; using the two lowest-risk groups as reference, the hazard ratio (95% confidence interval) was 11.3 (4.0-32.8) for the highest-risk group and difference in mortality at 15 years was 60% (50-70%). The combined model provided greater discriminatory ability (area under the curve = 0.78) than the clinical model alone (area under the curve = 0.71; P = 0.04). Molecular tumor markers can add to clinical variables to help distinguish lethal and indolent prostate cancer and hold promise to guide treatment decisions.

  • Mediterranean Diet Score and prostate cancer risk in a Swedish population-based case-control study
  • 2013
  • Ingår i: Journal of Nutritional Science. - : Cambridge University Press (CUP). - 2048-6790. ; 2
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.
