Clinical Characterization of Patients Diagnosed with Prostate Cancer and Undergoing Conservative Management: A PIONEER Analysis Based on Big Data. Eur Urol 2024; 85:457-465. [PMID: 37414703 DOI: 10.1016/j.eururo.2023.06.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 05/18/2023] [Accepted: 06/19/2023] [Indexed: 07/08/2023]
Abstract
BACKGROUND Conservative management is an option for prostate cancer (PCa) patients either with the objective of delaying or even avoiding curative therapy, or to wait until palliative treatment is needed. PIONEER, funded by the European Commission Innovative Medicines Initiative, aims at improving PCa care across Europe through the application of big data analytics. OBJECTIVE To describe the clinical characteristics and long-term outcomes of PCa patients on conservative management by using an international large network of real-world data. DESIGN, SETTING, AND PARTICIPANTS From an initial cohort of >100 000 000 adult individuals included in eight databases evaluated during a virtual study-a-thon hosted by PIONEER, we identified newly diagnosed PCa cases (n = 527 311). Among those, we selected patients who did not receive curative or palliative treatment within 6 mo from diagnosis (n = 123 146). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Patient and disease characteristics were reported. The number of patients who experienced the main study outcomes was quantified for each stratum and the overall cohort. Kaplan-Meier analyses were used to estimate the distribution of time to event data. RESULTS AND LIMITATIONS The most common comorbidities were hypertension (35-73%), obesity (9.2-54%), and type 2 diabetes (11-28%). The rate of PCa-related symptomatic progression ranged between 2.6% and 6.2%. Hospitalization (12-25%) and emergency department visits (10-14%) were common events during the 1st year of follow-up. The probability of being free from both palliative and curative treatments decreased during follow-up. Limitations include a lack of information on patients and disease characteristics and on treatment intent. CONCLUSIONS Our results allow us to better understand the current landscape of patients with PCa managed with conservative treatment. PIONEER offers a unique opportunity to characterize the baseline features and outcomes of PCa patients managed conservatively using real-world data. PATIENT SUMMARY Up to 25% of men with prostate cancer (PCa) managed conservatively experienced hospitalization and emergency department visits within the 1st year after diagnosis; 6% experienced PCa-related symptoms. The probability of receiving therapies for PCa decreased according to time elapsed after the diagnosis.

Deferred treatment of localized prostate cancer in the elderly: the impact of the age and stage at the time of diagnosis on the treatment decision. BJU Int 2000; 85:699-704.

Abstract
OBJECTIVE To assess the clinical behaviour of clinically localized prostate cancer in elderly patients monitored until progression, and the impact of clinical variables, i.e. clinical stage, Gleason score, the dynamics of prostate specific antigen (PSA) and age, on the natural history of the disease. PATIENTS AND METHODS Between February 1991 and January 1998, 54 patients (mean age 76.4 years, median 77 at the time of diagnosis) with clinically localized prostate cancer who elected for watchful waiting were identified. They were monitored regularly and treatment deferred until progression. Progression was defined as local stage progression (as assessed on a digital rectal examination), biochemical progression or metastasis. All patients who progressed were offered either radiation therapy or hormonal treatment. Each clinical variable was assessed by univariate and multivariate analysis to predict disease progression. The mean follow-up was 47 months. RESULTS Of the 54 patients, 28 (52%) progressed; 10 had biochemical, 11 local and four biochemical and local progression, and three developed metastasis. All the patients who progressed elected to receive hormonal treatment. The mean time to progression was 35 months. Gleason score (</= 6 and > 6), age (</= 75 and > 75 years) and serum PSA level (</= 10 and > 10 ng/mL) were statistically significant predictors of disease progression (P = 0.04, < 0.001 and 0.02, respectively). The clinical stage at the time of diagnosis had a borderline effect on disease progression (P = 0.06). On multivariate analysis, Gleason score and PSA level were statistically significant predictors of disease progression. CONCLUSION These results suggest that the treatment of prostate cancer should not be deferred in patients aged > 75 years with a good performance status when the biopsy has a Gleason score >/= 6 and the serum PSA level is >/= 10 ng/mL.
