Lunar phases and zodiac signs do not influence quality of radical cystectomy--a statistical analysis of 452 patients with invasive bladder cancer.

OBJECTIVE: To determine the influence of the lunar phases and the position of the moon in the zodiac on the frequency of complications and the survival of bladder cancer patients after radical cystectomy. It has been postulated that radical cystectomy performed during the waxing moon, or particularly at full moon, or at the zodiac sign Libra is associated with a poorer outcome. MATERIAL AND METHODS: We tested this hypothesis by evaluating the progression-free survival, the complication rate and the re-operation rate for 452 consecutive patients after radical cystectomy. In this retrospective review, the dates of surgery were allocated to the lunar phases and the zodiac signs. Based on these classifications, the patients were placed in groups which combined the lunar phase laws and differentiated between evidently unfavorable (full moon or waxing moon and/or the zodiac sign Libra; assigned to group 1) and favorable periods for surgery (new moon or waning moon and other signs of the zodiac apart from Libra; assigned to group 2). The mean follow-up was 49 months (range 0-158 months). RESULTS: A total of 244 patients (54%) were operated during an unfavorable period (group 1) and 208 (46%) patients during the auspicious period (group 2). The mean age, gender and kind of urinary derivation did not differ significantly in the two groups. Pathological tumor stages were evenly distributed according to the lunar phase groups (P = 0.713). We found no significant differences in the perioperative mortality rates, early re-operation rates, early complications, and late complications across the two groups. No significant differences in progression-free survival were observed when timing of cystectomy during the lunar cycle was considered (P = 0.231). CONCLUSIONS: Our analysis demonstrated no predictable influence of the lunar phase on survival or complications. Although this was not a prospective randomized trial, the statistical magnitude of the results do not support any recommendations for scheduling patients for radical cystectomy at any particular day of the lunar phase.

Radical retropubic vs. radical perineal prostatectomy: a comparison of relative benefits in four urban hospitals.

INTRODUCTION: The purpose of this study was to evaluate the oncological and functional outcome of retropubic and perineal approaches to radical prostatectomy. METHOD: Data from 1,304 patients who underwent either radical retropubic (RRP) or radical perineal prostatectomy (RPP) over a 12-year period were compared. Variables included age, prostate-specific antigen (PSA) level preoperative, prostate volume, Gleason score, estimated blood loss (EBL), blood transfusion rate (BTR), operative duration, surgical margin, pathological stage, short and long-term complication rates, impotence, and incontinence rates. RESULTS: RRP had a longer operative duration, higher EBL, higher BTR, and longer hospital stay. The 5-year biochemical-free survival rates were not significantly different between the two techniques. CONCLUSIONS: These results indicate there are no significant differences in oncological and functional outcomes between RRP and RPP. However, RPP demonstrates minimal EBL, low BTR, and shorter operative duration.

Validity of the CAPRA score to predict biochemical recurrence-free survival after radical prostatectomy. Results from a european multicenter survey of 1,296 patients.

PURPOSE: The CAPRA (Cancer of the Prostate Risk Assessment) score from the University of California, San Francisco provides a new statistical model to predict recurrence-free survival and pathological tumor stage after radical prostatectomy. It was originally developed using data from the CaPSURE (Cancer of the Prostate Strategic Urologic Research Endeavor) registry. To calculate the score, which ranges from 0 to 10, 5 clinical variables are needed, ie prostate specific antigen, Gleason sum, clinical tumor grade, percentage of positive biopsies and patient age. To date, the only external validation of the CAPRA score has been conducted using the SEARCH (Shared Equal Access Regional Cancer Hospital) database. The present study uses a German database to contribute to existing validation work and to test transferability of the CAPRA score to a sample that differs fundamentally from the SEARCH sample in terms of clinical features. MATERIALS AND METHODS: Data from 1,296 German patients after radical prostatectomy were used for validation. Mean followup was 56.5 (+/-35.4) months. Accuracy of prediction of recurrence-free survival and pathological tumor stage with the CAPRA score was analyzed using Kaplan-Meier analysis, proportional hazards regression, logistic regression and graphic representation. RESULTS: For the external validation of the CAPRA score, the underlying clinical variables of our study group were unfavorable compared to the original cohort from the CaPSURE data set. The recurrence-free survival rate decreased after 3 and 5 years from 100% to 97%, respectively, in the CAPRA score 0 to 1 group, and from 44% to 31%, respectively, in the CAPRA score of 7 or higher group. The hazard ratios of a biochemical recurrence per 1-group increase were 1.50 (95% CI 1.43-1.56) for the CAPRA sum score, 1.62 (95% CI 1.53-1.71) for the 7-group CAPRA score and 3.52 (95% CI 3.00-4.12) for the 3-group CAPRA score. Concordance indices between 0.78 and 0.81 suggested good predictive accuracy. Of the 5 CAPRA constituents 4 independently predicted recurrence-free survival, ie prostate specific antigen, Gleason sum, cT stage and percent of positive biopsies. Positive margins occurred in 13.1% of patients with a CAPRA score of 0 to 1 vs 62% of patients with a score of 7 to 10 (p <0.001). Organ confined tumors were present in 97.7% of patients with a CAPRA score of 0 to 1 vs 19.3% of those with a score of 7 to 10 (p <0.001). CONCLUSIONS: Despite different clinical features in the present patient cohort and the CaPSURE data set, the accuracy of the CAPRA nomogram in predicting recurrence-free survival was high. These results underscore the effectiveness and the clinical applicability of the CAPRA score which, in addition to patient counseling, may also be used for risk stratification in clinical studies.

Results from three municipal hospitals regarding radical cystectomy on elderly patients.

OBJECTIVE: Radical cystectomy is the standard treatment for invasive bladder carcinoma in elderly patients at major surgical centers. As yet no data are available as to the question whether radical surgery on the genitourinary tract of patients over 75 can also be carried out at municipal hospitals with comparable intra and postoperative morbidity, and respective mortality. MATERIALS AND METHODS: 452 radical cystectomies and urinary diversions as ileum conduits or ileum neobladders due to transitional cell carcinoma were carried out at three municipal hospitals between 1992 and 2004. At the time of the surgery, 44 patients (9.7%) were > or = 75 (75-84) (Group-1), by comparison 408 patients were younger than 75 (35-74) (Group-2). Comparisons are to be made between the groups for 30 day mortality, 30 day reoperation rate, early complication rate (< or = 3 months), late complication rate (> 3 months), progression-free survival, and overall survival. The results are to be discussed in view of the international literature. Mean follow-up was 49 months (median: 38 months). RESULTS: The perioperative mortality in Group-1 was 2.3% compared to 2.5% in Group-2 (p = 0.942). There was no significant difference in the perioperative mortality with regard to the different case load of the evaluated hospital. There were no significant group differences regarding the 30 day reoperation rate, early and late complications. Progression-free and overall survival of all patients after 5 years was 56.1% and 53.6% respectively; here again the differences between the age groups was not significant (p = 0.384 and p = 0.210). Our results for patients > or = 75 do not differ from the published data of large clinics with a high cystectomy frequency. CONCLUSIONS: Our data confirm that radical cystectomy on elderly patients can also be carried out in municipal hospitals with acceptable mortality and morbidity rates. Of prime importance is a careful patient selection based on comorbidity scores and possibly geriatric assessment.

Diagnostic value of tumour marker regression models in stage 1 marker-positive testicular cancer.

The decay pattern and half-life period evaluation of serum tumour markers are useful parameters in the management of testicular cancer in clinic stage 1. Alpha-fetoprotein and human chorionic gonadotropin serum levels measured after orchiectomy can be used to predict the tumour stage. However, the optimal strategy for marker analysis after orchiectomy has not yet been defined. In this article we describe a graphic interactive method which uses tumour marker clearance to help identify patients with occult metastases after orchiectomy.

Survival rates after radical cystectomy according to tumor stage of bladder carcinoma at first presentation.

INTRODUCTION: The aim of this study was to establish to what extent the survival rates of muscle-invasive bladder carcinoma are influenced by the tumor stage at initial presentation. PATIENTS AND METHODS: This study examined the clinical course of 230 patients who underwent radical cystectomy for bladder carcinoma from 1992 to 2002. The patients were divided into three groups according to the histological results of the initial and final transurethral tumor resection (TURB). In group 1 (n = 41) radical cystectomy was carried out for a superficial bladder carcinoma which had a high likelihood of progressing. Group 2 (n = 57) consisted of patients who displayed a superficial tumor stage when they first presented and developed progressive muscle-invasive bladder carcinoma under conservative treatment. Group 3 (n = 132) was made up of patients who were already at the muscle-invasive tumor stage in the course of primary TURB. The histopathological characteristics of all transurethral tumor resections and radical cystectomy were recorded. Progression-free survival and overall survival in the three groups were then compared. RESULTS: The average patient age when cystectomy was carried out was 63.9 (35-80) years and the average follow-up period was 38 months. An average of 2.3 (1-16) transurethral tumor resections were carried out before radical cystectomy (median = 1). Progression-free survival and overall survival of all 230 patients was 54 and 50%, respectively, after 5 years. The best result was a 74% progression-free 5-year survival rate with organ-confined lymph node-negative tumors (n = 106) which was statistically significant (p = 0.0004) compared to the progression-free 5-year survival rate of 50% for non-organ-confined, lymph node-negative tumors (n = 64). Lymph node-positive patients achieved a progression-free survival rate of 21% after 5 years regardless of the tumor infiltration. Patients in group 1 achieved a progression-free 5-year survival rate of 77% and an overall survival rate of 63% after 5 years. In group 2 patients achieved a progression-free survival rate of 51% after 5 years and an overall survival rate of 50%. In the case of primary muscle invasion (group 3), progression-free survival and overall survival were 49 and 46%, respectively, after 5 years. There was no significant difference between groups 2 and 3 with regard to their progression-free or overall survival rates (p > 0.35). However, both groups displayed a significantly poorer progression-free and overall survival rate compared with group 1 (p < 0.01). CONCLUSION: Our results show that superficial bladder carcinoma with tumor progress to muscle invasion does not have a better prognosis after radical cystectomy than initial muscle-invasive bladder carcinoma. Survival rates in this group can only be improved by singling out patients on the basis of risk factors at an earlier stage and carrying out a cystectomy.
