Relationship of Comorbidity, Age and Perioperative Complications in Patients Undergoing Radical Prostatectomy

Fröhner, Michael, Litz, Rainer, Manseck, Andreas, Hakenberg, Oliver W., Leike, Steffen, Albrecht, D.-Michael, Wirth, Manfred P. January 2001 (has links)
Objectives: To investigate the prevalence and distribution of comorbidity and its association with perioperative complications in patients undergoing radical prostatectomy (RPE). Methods: In 431 unselected RPE patients, the American Society of Anesthesiologists Physical Status classification (ASA-PS), the New York Heart Association classification of cardiac insufficiency (NYHA), the classification of angina pectoris of the Canadian Cardiovascular Society (CCS), height, weight, the body mass index (BMI), and the number of concomitant diseases (NCD) were assessed and related to perioperative cardiovascular complications. Results: In RPE patients less than 70 years old, comorbidity rose nearly continuously with increasing age. However, after reaching an age of 70 years, the proportion of NYHA-0 patients increased (60–64 years, 86%; 65–69 years, 85%; ≥70 years, 87%). Furthermore, the severe comorbidities decreased in patients selected for RPE aged 70 or more years. There was a nonsignificant trend towards higher comorbidity in patients with perioperative cardiovascular complications. Conclusions: These data suggest that documentation of the distribution of ASA-PS, CCS, NYHA and of concomitant diseases might be helpful to characterize the general health status and the degree of selection of prostate cancer treatment populations especially in series with a high portion of patients aged 70 or more years. Concerning perioperative complications, the individual predictive value of comorbidity seems to be poor in the radical prostatectomy setting. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Is Systematic Sextant Biopsy Suitable for the Detection of Clinically Significant Prostate Cancer?

Manseck, Andreas, Fröhner, Michael, Oehlschläger, Sven, Hakenberg, Oliver W., Friedrich, Katrin, Theissig, Franz, Wirth, Manfred P. January 2000 (has links)
Background: The optimal extent of the prostate biopsy remains controversial. There is a need to avoid detection of insignificant cancer but not to miss significant and curable tumors. In alternative treatments of prostate cancer, repeated sextant biopsies are used to estimate the response. The aim of this study was to investigate the reliability of a repeated systematic sextant biopsy as the standard biopsy technique in patients with significant tumors which are being considered for curative treatment. Methods: Systematic sextant biopsy was performed in vitro in 92 radical prostatectomy specimens. Of these patients, 81 (88.0%) had palpable lesions. Results: Of the 92 investigated patients, 70 (76.1%) had potentially curable pT2-3pN0 prostate cancers. In these patients, the cancer was detected only in 72.9% of cases by a repeated in vitro biopsy. In the pT2 tumors, there was a detection rate of only 66.7%. Conclusions: This study underlines the fact that a considerable number of significant and potentially curable tumors remain undetected by the conventional sextant biopsy. A negative sextant biopsy does not rule out significant prostate cancer. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Curative Treatment of Prostate Cancer

Wirth, Manfred P., Hakenberg, Oliver W. January 1999 (has links)
The guidelines for the curative treatment of prostate cancer presented by the German Society of Urology are discussed. They are based on the current knowledge of the outcomes of surgical and radiotherapeutic treatment for prostate cancer. Radical prostatectomy is recommended as the first-line treatment for organ-confined prostate cancer in patients with an individual life expectancy of at least 10 years. Radiotherapy can be considered as an alternative treatment modality, although current knowledge does not allow a definite assessment of the relative value of radiotherapy compared to radical prostatectomy. Locally advanced cT3 prostate cancer is overstaged in about 20% and curative treatment is possible in selected cases. Guidelines represent rules based on the available evidence. This implies that exceptions must be made whenever appropriate and that guidelines have to be reviewed regularly as new information becomes available. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

INTRODUÇÃO: O câncer de próstata (CaP) é o tipo mais comum entre os tumores malignos que afetam o homem. Dentre as opções terapêuticas para o tratamento precoce do CaP, destaca-se o tratamento cirúrgico com resultados satisfatórios de até 94% de cura nos casos localizados. A ressecção cirúrgica do CaP pode ser feita por três abordagens principais: prostatectomia radical retropúbica (PRR), prostatectomia radical laparoscópica (PRL) e mais recentemente a prostatectomia radical laparoscópica robô assistida (PRAR). Uma vez que existem várias alternativas terapêuticas para esse tipo de câncer, a qualidade de vida e satisfação relacionadas à avaliação, tornam-se muito importantes nos diferentes tipos de técnicas cirúrgicas. OBJETIVO: Comparar a qualidade de vida e o índice de satisfação nos pacientes submetidos a PRR e PRAR através de um estudo prospectivo e aleatorizado. MATERIAL E MÉTODOS: Através do Sistema Único de Saúde (SUS), 200 pacientes com diagnóstico de adenocarcinoma de próstata localizado, foram selecionados de forma aleatória para participarem do estudo, sendo então encaminhados entre março de 2010 a janeiro de 2011 para o Hospital Alemão Oswaldo Cruz (HAOC) para realizar PRAR, ou para o Instituto do Câncer do Estado de São Paulo (ICESP), para a realização de PRR. Todos os pacientes foram seguidos clinicamente de maneira padrão. Utilizamos questionário SF-36 da seguinte forma: no pré-operatório e no pós-operatório de 1, 3, 6, 12, 18 e 24 meses, além de outro elaborado para avaliar a satisfação dos pacientes no pós operatório de 6, 12 e 18 meses. Os dados obtidos foram avaliados estatisticamente com nível de significância de 5%. RESULTADOS: Foram então aplicados os questionários em 200 pacientes submetidos às cirurgias (grupos homogêneos com 100 pacientes para PRR e 100 para PRAR). De acordo com os domínios de qualidade de vida, os escores médios dos aspectos físicos, aspectos emocionais e saúde mental só variaram estatisticamente entre os momentos de avaliação, sendo os grupos iguais entre si para estes domínios. De acordo com aspectos sociais houve diferença entre os grupos independente do momento de avaliação, sendo maior nos pacientes submetidos a cirurgia aberta (p = 0,016). O nível de escolaridade e a renda familiar dos pacientes que realizaram a cirurgia robótica são maiores que as dos pacientes que realizaram a cirurgia aberta (p = 0,044 e p = 0,029 respectivamente). De acordo com o grau de satisfação pós cirurgia, encontramos que os pacientes que fizeram cirurgia robótica apresentam um maior grau de satisfação com a cirurgia que aqueles submetidos a cirurgia aberta (p < 0,001). O que mais incomoda ou preocupa o paciente que realiza a cirurgia aberta é a disfunção erétil enquanto que nos pacientes que fazem à cirurgia robótica a preocupação se distribui entre cura, impotência e perda urinária. CONCLUSÃO: Demonstramos que a maioria dos aspectos de qualidade de vida são semelhantes entre os pacientes submetidos a PRR e PRAR com exceção dos aspectos sociais que foram maiores nos pacientes submetidos ao procedimento aberto, demonstramos ainda que o índice de satisfação dos pacientes é maior no procedimento robótico, entretanto a grande maioria dos pacientes realizariam o mesmo tratamento quando questionados / INTRODUCTION: Prostate cancer (PCa) is the most common malignant tumors that affect man. Among the treatment options for early treatment of PCa, stands out the surgical treatment with satisfactory results, achieving cure results of up to 94% in localized cases. Surgical resection of PCa can be done through three main approaches, which are radical retropubic prostatectomy (RRP), laparoscopic radical prostatectomy (LRP) and more recently robotic-assisted laparoscopic radical prostatectomy (RALRP). Since there are several alternative therapies for this cancer, quality of life and satisfaction related to the evaluation of different types of surgery became very important. OBJECTIVE: Evaluate the two most widely used techniques: RRP and RALRP through a prospective randomized study, checking the satisfaction and quality of life in patients who have undergone these treatments. MATERIAL AND METHODS: The choice of surgical approach of the patient occurred randomly and the patients were selected through the Unified Health System (SUS) and sent to the Oswaldo Cruz Hospital (HAOC) for RALRP (robotic-assisted laparoscopic radical prostatectomy) or sent to the Cancer Institute of the State of São Paulo (ICESP) for RRP (radical retropubic prostatectomy), between March 2010 and January 2011. All patients were followed clinically in a standard way through a questionnaire, SF-36 and a questionnaire to evaluate their satisfaction. It was also verified the level of regret in post-surgery within 1, 3, 6, 12 and 24 months and the level of satisfaction was verified at 6 12 and 18 months post-surgery. The data were statistically evaluated with a significance level of 5%. RESULTS: We then applied the questionnaires in 200 patients who underwent surgery, and 100 patients who underwent RRP and 100 patients who underwent RALRP. The groups were quite homogeneous. According to the domains of quality of life, the average scores of physical, emotional and mental health only varied significantly among time points of evaluation, and the groups were equal to each other for these domains. According to the social aspects there were differences between the groups regardless of the time of evaluation, being higher in patients who underwent open surgery (p = 0.016). The education level and family income of patients who underwent robotic surgery are higher than of patients who underwent open surgery (p = 0.044 and p = 0.029 respectively). According to the level of satisfaction post-surgery, we realized that robotic surgery patients have a higher level of satisfaction about the surgery than those undergone open surgery (p < 0.001). The most signicant thing that bothers or worries the open surgery patients is sexual impotence while in robotic surgery patients, the concern is distributed among cure, impotence and urinary incontinence. CONCLUSION: We demonstrated that most aspects of quality of life are similar among patients undergoing RRP and RALRP except social aspects that were higher in patients undergone open surgery. We further demonstrated that the rate of satisfaction is higher in the robotic procedure patients. However, when questioned, the vast majority of patients would do the same treatment

Competing Mortality Contributes to Excess Mortality in Patients with Poor-Risk Lymph Node-Positive Prostate Cancer Treated with Radical Prostatectomy

Fröhner, Michael, Scholz, Albrecht, Koch, Rainer, Hakenberg, Oliver W., Baretton, Gustavo B., Wirth, Manfred P. 14 February 2014 (has links) (PDF)
Background: Factors predicting survival in men with lymph node-positive prostate cancer are still poorly defined. Patients and Methods: 193 prostate cancer patients with histopathologically proven lymph node involvement with a median follow-up of 7.3 years were studied. 94% of patients received immediate hormonal therapy. Kaplan-Meier curves were calculated to evaluate overall survival rates and compared with the log-rank test. Cumulative disease-specific and competing mortality rates were calculated by competing risk analysis and compared with the Pepe-Mori test. Cox proportional hazard models were used to determine the independent significance of predictors of all-cause mortality. Results: Age (70 years or older vs. younger), Gleason score (8–10 vs. 7 or lower) and the number of involved nodes (3 or more vs. 1–2) were identified as independent predictors of all-cause mortality. When patients with 0–1 of these risk factors were compared with those with 2–3 risk factors, all-cause (rates after 10 years 21% vs. 71%, p < 0.0001), disease-specific (12 vs. 37%, p = 0.009) and competing mortality (9 vs. 33%, p = 0.02) differed significantly. Conclusions: Some of the excess mortality in patients with poor-risk lymph node-positive prostate cancer may be attributed to increased competing mortality, possibly caused by an interaction between comorbid diseases and hormonally treated persistent or progressive prostate cancer. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Is There a Relationship between the Amount of Tissue Removed at Transurethral Resection of the Prostate and Clinical Improvement in Benign Prostatic Hyperplasia

Hakenberg, Oliver W., Helke, Christian, Manseck, Andreas, Wirth, Manfred P. 21 February 2014 (has links) (PDF)
Objective: To assess in a prospective trial the influence of the amount of tissue resected at transurethral resection of the prostate (TURP) for benign prostatic enlargement on the symptom improvement as assessed by symptom scores. Methods: Between December 1996 and August 1998 a total of 138 men (mean age 68.2, range 53–89) with symptomatic benign prostatic enlargement who underwent TURP participated in this prospective study. Patients were assessed preoperatively with the International Prostate Symptom Score (IPSS), the American Urological Association Bother Score (AUA–BS) and the Benign Prostatic Hyperplasia Impact Index (BPH–II) as well as urinary flow rate measurements (Qmax) and prostate volume (PV) and residual urine determination by ultrasound. The amount of tissue resected was weighed. Patients were followed with reevaluation of Qmax, residual urine and the symptom and bother scores at 3 and 6 months. Results: A close correlation between preoperative PV (mean 49.0 ml, SD 22.0, range 13–140) and the resected tissue weight (RTW, mean 24.7 g, SD 18.0, range 6–128) was seen (r = 0.75, p<0.001). Age was correlated with preoperative PV (r = 0.23, p<0.05). While significant mean improvements in Qmax, residual volume and IPSS, AUA–BS and BPH–II were found 3 and 6 months postoperatively, a negative correlation was seen between the RTW and the IPSS, the AUA–BS and the BPH–II 3 months after TURP (r = –0.23, p<0.024; r = –0.23, p<0.025; r = –0.20, p = 0.05). No statistically significant correlation was seen between symptom change and the percentage of PV removed or the residual prostatic weight. Classification of the patients into groups depending on preoperative PV (<30, 31–50, 51–70 and >70 ml) showed a tendency for patients with larger PV to gain more symptom improvement postoperatively. Conclusions: Early symptom improvement after TURP will depend on the amount of tissue removed but the relationship is weak and affected by several other confounding factors. Apparently, the symptomatic improvement after TURP is not primarily dependent on the relative completeness of the resection. Patients with larger prostates and larger RTW tend to gain more symptomatic benefit from TURP than do patients with smaller prostates. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

A Review of Studies of Hormonal Adjuvant Therapy in Prostate Cancer

Wirth, Manfred, Fröhner, Michael 21 February 2014 (has links) (PDF)
There is increasing interest in the use of adjuvant hormonal therapies, which are given after the resection or destruction of all gross disease, in early-stage prostate cancer, as a significant proportion of patients experience progression and/or die from the disease despite undergoing therapy with curative intent. Several retrospective studies suggest that adjuvant hormonal therapy may improve long-term outcome after radical surgery in men with positive lymph nodes, although this approach has yet to be studied in a prospective setting. No studies of adjuvant therapy for patients with extracapsular extension at surgery have been completed, but in an interim analysis of an open controlled trial, adjuvant flutamide significantly improved progression-free survival at 4 years. Three prospective studies in the radiotherapy setting have shown that adjuvant luteinizing hormone-releasing hormone (LH-RH) agonist therapy significantly improves progression-free and/or overall survival. Future studies need to define patient subgroups who will benefit most from adjuvant therapy. The side effects of the different therapeutic options also need to be compared. It is hoped that many of the outstanding questions concerning adjuvant hormonal therapy will be answered by the ongoing Bicalutamide Early Prostate Cancer Programme. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.
