Der vorliegende Beitrag geht der Frage nach, ob die schweizerische Demokratie bereits ab der Bundesstaatsgründung im Jahr 1848 eine ausgeprägte Konsensusdemokratie war. Zur Beantwortung dieser Fragestellung bedient sich die Studie des Konzepts von Arend Lijphart (2012) mit der Unterscheidung von Mehrheits- und Konsensusdemokratie. Anhand von Literatur- und Dokumentenanalysen wurden Lijpharts Indikatoren für den schweizerischen Bundesstaat von 1848–1874 codiert. Die Ergebnisse zeigen, dass das politische System der neu gegründeten Schweiz auf Lijpharts Demokratiekarte insbesondere auf der horizontalen Machtteilungsdimension wie erwartet sehr nahe an der Position der USA zu liegen kommt.

BACKGROUND Whether the commonly used bacillus Calmette-Guérin (BCG) strains Connaught and Tice confer different treatment responses in non-muscle-invasive bladder cancer (NMIBC) is unknown. OBJECTIVES To compare clinical efficacy, immunogenicity, and genetics of BCG Connaught and Tice. DESIGN, SETTING, AND PARTICIPANTS A prospective randomized single-institution trial with treatment of 142 high-risk NMIBC patients with BCG Connaught or Tice. INTERVENTION Patients were randomized to receive six instillations of BCG Connaught or Tice. For experimental studies, BCG strains were compared in C57Bl/6 mice. Bladders and lymphoid tissues were analyzed by cytometry and the latter cultivated to detect live BCG. BCG genomic DNA was sequenced and compared with reference genomes. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Recurrence-free survival was the primary end point of the clinical study. The Kaplan-Meier estimator was used for estimating survival and time-to-event end points. Nonparametric tests served for the analysis of the in vivo results. RESULTS AND LIMITATIONS Treatment with BCG Connaught conferred significantly greater 5-yr recurrence-free survival compared with treatment with BCG Tice (p=0.0108). Comparable numbers of patients experienced BCG therapy-related side effects in each treatment group (p=0.09). In mice, BCG Connaught induced stronger T-helper cell 1-biased responses, greater priming of BCG-specific CD8(+) T cells, and more robust T-cell recruitment to the bladder than BCG Tice. Genome sequencing of the BCG strains revealed candidate genes potentially involved in the differential clinical responses. CONCLUSIONS BCG strain may have an impact on treatment outcome in NMIBC immunotherapy. PATIENT SUMMARY We compared the efficacy of two commonly used bacillus Calmette-Guérin (BCG) strains for the treatment of NMIBC and found that treatment with BCG Connaught prevented recurrences more efficiently than BCG Tice. Comparison of the immunogenicity of the two strains in mice indicated superior immunogenicity of BCG Connaught. We also identified genetic differences that may explain the differential efficacy of the Connaught and Tice BCG strains. TRIAL REGISTRATION NCT00003779.

BACKGROUND The impact of prognostic factors in T1G3 non-muscle-invasive bladder cancer (BCa) patients is critical for proper treatment decision making. OBJECTIVE To assess prognostic factors in patients who received bacillus Calmette-Guérin (BCG) as initial intravesical treatment of T1G3 tumors and to identify a subgroup of high-risk patients who should be considered for more aggressive treatment. DESIGN, SETTING, AND PARTICIPANTS Individual patient data were collected for 2451 T1G3 patients from 23 centers who received BCG between 1990 and 2011. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Using Cox multivariable regression, the prognostic importance of several clinical variables was assessed for time to recurrence, progression, BCa-specific survival, and overall survival (OS). RESULTS AND LIMITATIONS With a median follow-up of 5.2 yr, 465 patients (19%) progressed, 509 (21%) underwent cystectomy, and 221 (9%) died because of BCa. In multivariable analyses, the most important prognostic factors for progression were age, tumor size, and concomitant carcinoma in situ (CIS); the most important prognostic factors for BCa-specific survival and OS were age and tumor size. Patients were divided into four risk groups for progression according to the number of adverse factors among age ≥ 70 yr, size ≥ 3 cm, and presence of CIS. Progression rates at 10 yr ranged from 17% to 52%. BCa-specific death rates at 10 yr were 32% in patients ≥ 70 yr with tumor size ≥ 3 cm and 13% otherwise. CONCLUSIONS T1G3 patients ≥ 70 yr with tumors ≥ 3 cm and concomitant CIS should be treated more aggressively because of the high risk of progression. PATIENT SUMMARY Although the majority of T1G3 patients can be safely treated with intravesical bacillus Calmette-Guérin, there is a subgroup of T1G3 patients with age ≥ 70 yr, tumor size ≥ 3 cm, and concomitant CIS who have a high risk of progression and thus require aggressive treatment.
