Complications following radical cystectomy for bladder cancer in the elderly

CONTEXT: The incidence of bladder cancer increases with advancing age. Considering the increasing life expectancy and the increasing proportion of elderly people in the general population, radical cystectomy will be considered for a growing number of elderly patients who suffer from muscle-invasive or recurrent bladder cancer. OBJECTIVE: This article reviews contemporary complication and mortality rates after radical cystectomy in elderly patients and the relationship between age and short-term outcome after this procedure. EVIDENCE ACQUISITION: A literature review was performed using the PubMed database with combinations of the following keywords cystectomy, elderly, complications, and comorbidity. English-language articles published in the year 2000 or later were reviewed. Papers were included in this review if the authors investigated any relationship between age and complication rates with radical cystectomy for bladder cancer or if they reported complication rates stratified by age groups. EVIDENCE SYNTHESIS: Perioperative morbidity and mortality are increased and continence rates after orthotopic urinary diversion are impaired in elderly patients undergoing radical cystectomy. Complications are frequent in this population, particularly when an extended postoperative period (90 d instead of 30 d) is considered. CONCLUSIONS: Although age alone does not preclude radical cystectomy for muscle-invasive or recurrent bladder cancer or for certain types of urinary diversion, careful surveillance is required, even after the first 30 d after surgery. Excellent perioperative management may contribute to the prevention of morbidity and mortality of radical cystectomy, supplementary to the skills of the surgeon, and is probably a reason for the better perioperative results obtained in high-volume centers.

The impact of lymphadenectomy and lymph node metastasis on the outcomes of radical cystectomy for bladder cancer

CONTEXT: The presence of lymph node metastases and the extent of lymphadenectomy have both been shown to influence the outcome of patients with muscle-invasive bladder cancer. OBJECTIVE: Current standards for detection of lymph node metastases, lymph-node mapping studies, histopathologic techniques, and risk factors in relation to lymph node involvement are discussed. The impact of lymph node metastases and the extent of lymphadenectomy on the outcome of patients treated with radical cystectomy are analyzed. EVIDENCE ACQUISITION: A systematic literature review of bladder cancer and lymph nodes was performed searching the electronic databases Pubmed/Medline, Cochrane, and Embase. Articles were selected based on title, abstract, study format, and content by a consensus of all participating authors. EVIDENCE SYNTHESIS: Lymph node status is highly consequential in bladder cancer patients because the presence of lymph node metastases is predictive of poor outcome. Knowledge of primary landing sites of lymph node metastases is important for optimum therapeutic management. Accurate pathologic work-ups of resected lymph node tissue are mandatory. Molecular markers could potentially guide therapeutic decisions in the future because they may enable the detection of micrometastatic disease. In current series, radical cystectomy with an extended lymphadenectomy seems to provide a clinically meaningful therapeutic benefit compared with a limited approach. However, the anatomic boundaries of lymph node dissection are still under debate. Therefore, large prospective multicenter trials are needed to validate the influence of extended lymph node dissection on disease-specific survival. CONCLUSIONS: An extended pelvic lymph node dissection (encompassing the external iliac vessels, the obturator fossa, the lateral and medial aspects of the internal iliac vessels, and at least the distal half of the common iliac vessels together with its bifurcation) can be curative in patients with metastasis or micrometastasis to a few nodes. Therefore, the procedure may be offered to all patients undergoing radical cystectomy for invasive bladder cancer.

Removal of Limited Nodal Disease in Patients Undergoing Radical Prostatectomy: Long-Term Results Confirm a Chance for Cure

Abstract PURPOSE: In 2003 we reported on the outcomes of 88 patients with node positive disease who underwent radical prostatectomy and pelvic lymph node dissection (median 21 nodes) between 1989 and 1999. Patients with limited nodal disease appeared to have a good chance of long-term survival, even without immediate adjuvant therapy (androgen deprivation therapy and/or radiotherapy). In this study we update the followup in these patients and verify the reported projected probability of survival. MATERIALS AND METHODS: The projected 10-year cancer specific survival probability after the initially reported followup of 3.2 years was 60% for these patients with node positive disease. The outcome has been updated after a median followup of 15.6 years. RESULTS: Of the 39 patients with 1 positive node 7 (18%) remained biochemically relapse-free, 11 (28%) showed biochemical relapse only and 21 (54%) experienced clinical progression. Of these 39 patients 22 (57%) never required deferred androgen deprivation therapy and 12 (31%) died of prostate cancer. All patients with 2 (20) or more than 2 (29) positive nodes experienced biochemical relapse and only 5 (10%) of these 49 experienced no clinical progression. Of these 49 patients 39 (80%) received deferred androgen deprivation therapy. CONCLUSIONS: Biochemical relapse is likely in patients with limited nodal disease after radical prostatectomy and pelvic lymph node dissection, but for 47% of patients this does not imply death from prostate cancer. Patients with 1 positive node have a good (75%) 10-year cancer specific survival probability and a 20% chance of remaining biochemical relapse-free even without immediate adjuvant therapy.

Local recurrence after retropubic radical prostatectomy for prostate cancer does not exclusively occur at the anastomotic site

What's known on the subject? and What does the study add? Local recurrence after radical prostatectomy (RP) for clinically organ-confined prostate cancer is largely assumed to occur at the anastomotic site, as reflected in European and North American guidelines for adjuvant and salvage radiotherapy after RP. However, the exact site of local recurrence often remains undetermined. The present study shows that roughly one out of five patients with local recurrence after RP has histologically confirmed tumour deposits at the resection site of the vas deferens, clearly above the anastomotic site. This should be considered when offering ‘blind’ radiotherapy to the anastomotic site in patients with biochemical recurrence alone. Objective To determine the anatomical pattern of local recurrence and the corresponding clinical and pathological variables of patients treated with retropubic radical prostatectomy (RRP). Patients and Methods In all, 41 patients with biopsy confirmed local recurrence after extended pelvic lymph node dissection and RRP performed between January 1992 and December 2009 at a single tertiary referral academic centre were retrospectively studied. The site of local recurrence as assessed on computed tomography or magnetic resonance imaging was reviewed. Two sites were identified: the vesicourethral anastomotic site and the cranial resection margin of the surgical bed, where the vas deferens was transected and clipped. Age and serum prostate-specific antigen (PSA) level at RRP, pathological tumour and nodal stage, Gleason score, tumour location, surgical margin status, age and serum PSA level at the time of local recurrence, and time to diagnosis of local recurrence were assessed for the two sites and compared with the chi-square or Wilcoxon rank sum tests as appropriate. Results Local recurrence occurred at the anastomotic site in 31/41 (76%) patients and at the resection site of the vas deferens in nine of 41 (22%) patients. One patient had distinct lesions at both sites. There was no significant difference in any of the clinical and pathological variables between patients with local recurrence in the former and latter site. Conclusion Most local recurrences after RRP occur exclusively at the anastomotic site. However, 22% of locally recurrent cases had tumour at the resection site of the vas deferens. This should be taken into account when considering adjuvant or salvage radiation therapy.

Restrictive deferred hydration combined with preemptive norepinephrine infusion during radical cystectomy reduces postoperative complications and hospitalization time: a randomized clinical trial.

BACKGROUND Anesthetics and neuraxial anesthesia commonly result in vasodilation/hypotension. Norepinephrine counteracts this effect and thus allows for decreased intraoperative hydration. The authors investigated whether this approach could result in reduced postoperative complication rate. METHODS In this single-center, double-blind, randomized, superiority trial, 166 patients undergoing radical cystectomy and urinary diversion were equally allocated to receive 1 ml·kg·h of balanced Ringer's solution until the end of cystectomy and then 3 ml·kg·h until the end of surgery combined with preemptive norepinephrine infusion at an initial rate of 2 µg·kg·h (low-volume group; n = 83) or 6 ml·kg·h of balanced Ringer's solution throughout surgery (control group; n = 83). Primary outcome was the in-hospital complication rate. Secondary outcomes were hospitalization time, and 90-day mortality. RESULTS In-hospital complications occurred in 43 of 83 patients (52%) in the low-volume group and in 61 of 83 (73%) in the control group (relative risk, 0.70; 95% CI, 0.55-0.88; P = 0.006). The rates of gastrointestinal and cardiac complications were lower in the low-volume group than in the control group (5 [6%] vs. 31 [37%]; relative risk, 0.16; 95% CI, 0.07-0.39; P < 0.0001 and 17 [20%] vs. 39 [48%], relative risk, 0.43; 95% CI, 0.26-0.60; P = 0.0003, respectively). The median hospitalization time was 15 days [range, 11, 27d] in the low-volume group and 17 days [11, 95d] in the control group (P = 0.02). The 90-day mortality was 0% in the low-volume group and 4.8% in the control group (P = 0.12). CONCLUSION A restrictive-deferred hydration combined with preemptive norepinephrine infusion during radical cystectomy and urinary diversion significantly reduced the postoperative complication rate and hospitalization time.

Intraoperative Continuous Norepinephrine Infusion Combined with Restrictive Deferred Hydration Significantly Reduces the Need for Blood Transfusion in Patients Undergoing Open Radical Cystectomy: Results of a Prospective Randomised Trial

BACKGROUND Open radical cystectomy (ORC) is associated with substantial blood loss and a high incidence of perioperative blood transfusions. Strategies to reduce blood loss and blood transfusion are warranted. OBJECTIVE To determine whether continuous norepinephrine administration combined with intraoperative restrictive hydration with Ringer's maleate solution can reduce blood loss and the need for blood transfusion. DESIGN, SETTING, AND PARTICIPANTS This was a double-blind, randomised, parallel-group, single-centre trial including 166 consecutive patients undergoing ORC with urinary diversion (UD). Exclusion criteria were severe hepatic or renal dysfunction, congestive heart failure, and contraindications to epidural analgesia. INTERVENTION Patients were randomly allocated to continuous norepinephrine administration starting with 2 μg/kg per hour combined with 1 ml/kg per hour until the bladder was removed, then to 3 ml/kg per hour of Ringer's maleate solution (norepinephrine/low-volume group) or 6 ml/kg per hour of Ringer's maleate solution throughout surgery (control group). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Intraoperative blood loss and the percentage of patients requiring blood transfusions perioperatively were assessed. Data were analysed using nonparametric statistical models. RESULTS AND LIMITATIONS Total median blood loss was 800 ml (range: 300-1700) in the norepinephrine/low-volume group versus 1200 ml (range: 400-2800) in the control group (p<0.0001). In the norepinephrine/low-volume group, 27 of 83 patients (33%) required an average of 1.8 U (±0.8) of packed red blood cells (PRBCs). In the control group, 50 of 83 patients (60%) required an average of 2.9 U (±2.1) of PRBCs during hospitalisation (relative risk: 0.54; 95% confidence interval [CI], 0.38-0.77; p=0.0006). The absolute reduction in transfusion rate throughout hospitalisation was 28% (95% CI, 12-45). In this study, surgery was performed by three high-volume surgeons using a standardised technique, so whether these significant results are reproducible in other centres needs to be shown. CONCLUSIONS Continuous norepinephrine administration combined with restrictive hydration significantly reduces intraoperative blood loss, the rate of blood transfusions, and the number of PRBC units required per patient undergoing ORC with UD.

Epidural Analgesia during Open Radical Prostatectomy Does Not Improve Long-Term Cancer-Related Outcome: A Retrospective Study in Patients with Advanced Prostate Cancer

Background A beneficial effect of regional anesthesia on cancer related outcome in various solid tumors has been proposed. The data on prostate cancer is conflicting and reports on long-term cancer specific survival are lacking. Methods In a retrospective, single-center study, outcomes of 148 consecutive patients with locally advanced prostate cancer pT3/4 who underwent retropubic radical prostatectomy (RRP) with general anesthesia combined with intra- and postoperative epidural analgesia (n=67) or with postoperative ketorolac-morphine analgesia (n=81) were reviewed. The median observation time was 14.00 years (range 10.87-17.75 yrs). Biochemical recurrence (BCR)-free, local and distant recurrence-free, cancer-specific, and overall survival were estimated using the Kaplan-Meier technique. Multivariate Cox proportional-hazards regression models were used to analyze clinicopathologic variables associated with disease progression and death. Results The survival estimates for BCR-free, local and distant recurrence-free, cancer-specific survival and overall survival did not differ between the two groups (P=0.64, P=0.75, P=0.18, P=0.32 and P=0.07). For both groups, higher preoperative PSA (hazard ratio (HR) 1.02, 95% confidence interval (CI) 1.01-1.02, P<0.0001), increased specimen Gleason score (HR 1.24, 95% CI 1.06-1.46, P=0.007) and positive nodal status (HR 1.66, 95% CI 1.03-2.67, P=0.04) were associated with higher risk of BCR. Increased specimen Gleason score predicted death from prostate cancer (HR 2.46, 95% CI 1.65-3.68, P<0.0001). Conclusions General anaesthesia combined with epidural analgesia did not reduce the risk of cancer progression or improve survival after RRP for prostate cancer in this group of patients at high risk for disease progression with a median observation time of 14.00 yrs.

Unaltered oncological outcomes of radical cystectomy with extended lymphadenectomy over three decades

OBJECTIVE To evaluate oncological outcome trends over the last three decades in patients after radical cystectomy (RC) and extended pelvic lymph node (LN) dissection. PATIENTS AND METHODS Retrospective analysis of the University of Southern California (USC) RC cohort of patients (1488 patients) operated with intent to cure from 1980 to 2005 for biopsy confirmed muscle-invasive urothelial bladder cancer. To focus on outcomes of unexpected (cN0M0) LN-positive patients, the USC subset was extended with unexpected LN-positive patients from the University of Berne (UB) (combined subgroup 521 patients). Patients were grouped and compared according to decade of surgery (1980-1989/1990-1999/≥2000). Survival probabilities were calculated with Kaplan-Meier plots, log-rank tests compared outcomes according to decade of surgery, followed by multivariable verification. RESULTS The 10-year recurrence-free survival was 78-80% in patients with organ-confined, LN-negative disease, 53-60% in patients with extravesical, yet LN-negative disease and ≈30% in LN-positive patients. Although the number of patients receiving systemic chemotherapy increased, no survival improvement was noted in either the entire USC cohort, or in the combined LN-positive USC-UB cohort. In contrast, patient age at surgery increased progressively, suggesting a relative survival benefit. CONCLUSIONS Radical surgery remains the mainstay of therapy for muscle-invasive bladder cancer. Yet, our study reveals predictable outcomes but no survival improvement in patients undergoing RC over the last three decades. Any future survival improvements are likely to result from more effective systemic treatments and/or earlier detection of the disease.

Timing and outcomes for radical cystectomy in nonmuscle invasive bladder cancer

PURPOSE OF REVIEW To provide an overview on the available clinical and pathological factors in high-risk nonmuscle invasive bladder cancer (NMIBC) patients that help to approximate the risk of progression to muscle invasion and identify 'the' patients requiring timely cystectomy. The value of a high-quality transurethral tumor resection is pointed out. Outcomes following radical cystectomy are compared with a primarily bladder preserving strategy. RECENT FINDINGS Carcinoma in situ within the prostatic urethra of NMIBC patients impacts on patient's outcome. Therefore, biopsies taken from the prostatic urethra improve the initial tumor staging accuracy. Lamina propria substaging may provide more detailed prognostic information. Lympho-vascular invasion within the transurethral resection specimen may help to detect patients who benefit from timely cystectomy. Recent findings from patients undergoing radical cystectomy including super-extended lymphadenectomy for clinically NMIBC confirm the substantial rate (25%) of tumor understaging. The fact that almost 10% were found to harbor lymph node metastases underlines the necessity to perform a meticulous lymphadenectomy in NMIBC patients undergoing radical cystectomy. SUMMARY High-quality transurethral bladder tumor resection including underlying muscle fibers is of utmost importance. Nevertheless, tumor understaging remains an issue of concern and warrants the value of a second transurethral resection in high-risk NMIBC patients. There is a persisting lack of rigid therapeutic recommendations in patients with high-risk NMIBC. Instead, treatment strategy is based on individual risk factors. However, irrespective of initial treatment strategy, there is a subgroup of high-risk NMIBC patients with progressive disease, leading almost inevitably to death.

Immigrant Incorporation in Western Europe

Immigrant incorporation (or integration) is a subfield of migration studies, and it constitutes a genuinely interdisciplinary undertaking of sociologists, political scientists, anthropologists, lawyers, and historians. In none of these disciplines, however, has it carved out an established niche for itself. In contrast to the United States, where the study of immigrant integration (or “assimilation” as US researchers prefer to say) is more firmly grounded in sociology than in political science, a characteristic of the European scene is a larger prominence of political scientists, macro comparativists, and legal-institutional scholars. This reflects the fact that immigrant integration in Europe is, to a much larger degree than in the United States, framed by public policies, and it often goes along with major transformations of state institutions (most importantly citizenship) and national identities. European states (even France) are ethnic nation-states, where sedentariness and not moving is the norm, and they stand for countries that are much less attuned to, and constituted by, international migration than the classic immigrant nations of North America and Oceania. Overall, European scholarship is marked, on one side, by single-country studies by national experts, which are often solicited by their respective governments interested in policy advice (but increasingly also supported by supranational research bodies). On the other side, most agenda-setting work has grown out of qualitative single-person studies (often dissertations) by macro sociologists and political comparativists not (or only incidentally) rooted in national university systems and disconnected from policy contexts. The field is in need of further conceptual development and of theoretically reflected, genuinely comparative work of the second type, which is mostly off the public funding radar.

Tracks of immigrant political incorporation

Models of Immigrant Political Incorporation brings together a multidisciplinary group of scholars to consider pathways by which immigrants may be incorporated into the political processes of western democracies. It builds on a rich tradition of studying immigrant incorporation, but each chapter innovates by moving beyond singular accounts of particular groups and locations toward a general causal model with the scope and breadth to apply across groups, places, and time. Models of Immigrant Political Incorporation addresses three key analytic questions: what, if anything, are the distinctive features of immigrants or immigrant groups? How broadly should one define and study politics? What are the initial premises for analyzing pathways toward incorporation; does one learn more by starting from an assumption of racialization and exclusion or from an assumption of engagement and inclusion? While all models engage with all three key analytic questions, chapters vary in their relative focus on one or another, and in the answers they provide. Most include graphical illustrations of the model, as well as extended examples applying the model to one or more immigrant populations. At a time when research on immigrant political incorporation is rapidly accumulating - and when immigrants are increasingly significant political actors in many democratic polities — this volume makes a timely and valuable intervention by pushing researchers to articulate causal dynamics, provide clear definitions and measurable concepts, and develop testable hypotheses. Furthermore, the wide array of frameworks examining how immigrants become part of a polity or are shunted aside ensure that activists and analysts alike will find useful insights. By including historians, sociologists, and political scientists, by ranging across North America and Western Europe, by addressing successful and failed incorporative efforts, this handbook offers guides for anyone seeking to develop a dynamic, unified, and supple model of immigrant political incorporation.
