    Robot-assisted radical cystectomy (RARC) is an emerging operative alternative to open surgery for the management of invasive bladder cancer. Studies from single institutions provide limited data due to the small number of patients. In order to better understand the related outcomes, a world-wide consortium was established in 2006 of patients undergoing RARC, called the International Robotic Cystectomy Consortium (IRCC). Thus far, the IRCC has reported its findings on various areas of operative interest and continues to expand its capacity to include other operative modalities and transform it into the International Radical Cystectomy Consortium. This article summarizes the findings of the IRCC and highlights the future direction of the consortium. PMID:25097319

    This retrospective study evaluates the morbidity and outcome of cystectomy and urinary diversion in octogenarians with invasive bladder cancer. Records of all patients older than 80 years who underwent cystectomy during the last 10 years were analyzed retrospectively. Among 565 cystectomies, 11(< 2%) patients were identified and evaluated for intraoperative and postoperative complications and mortality post surgery. The median age was 82 years. One female and ten male patients were selected. Eight patients were hypertensive, three were diabetic, one had coronary artery disease, two had chronic lung disease and one had depression. Seven patients presented with hematuria, two had lower urinary tract symptoms and two presented with renal failure who were optimized for renal function. All patients had ileal conduit as the form of urinary diversion. Simultaneous urethrectomy was done in two patients. Median surgical time was 5 h. Median hospital stay after surgery was 10 days. Four patients had pneumonitis and one patient developed hemiplegia, but all patients were eventually discharged. One patient expired due to stent septicemia within one month after discharge. Follow-up ranged from four months to five years. Three patients expired three years after surgery—one due to disease recurrence and the other two due to unrelated cause. One patient was lost to follow-up and six patients are doing well. Our results support the use of cystectomy in octogenarians with invasive bladder cancer, which has acceptable morbidity and mortality, and offers the best chance for sustained disease-free quality survival.

    Objective Laparoscopic radical cystectomy (LRC) has emerged as a minimally invasive alternative to open radical cystectomy (ORC). This review focuses on patient selection criteria, technical aspects and postoperative outcomes of LRC. Methods Material for the review was obtained by a PubMed search over the last 10 years, using the keywords ‘laparoscopic radical cystectomy’ and ‘laparoscopic bladder cancer’ in human subjects. Results Twenty-two publications selected for relevance and content were used for this review from the total search yield. The level of evidence was IIb and III. LRC results in comparable short- and intermediate-range oncological outcomes to ORC, with generally longer operative times but decreased blood loss, postoperative pain and hospital stay. Overall operative and postoperative morbidity are equivalent. Conclusion In experienced hands, LRC is an acceptable minimally invasive alternative to ORC in selected patients, with the main advantage of decreased blood loss and postoperative pain, as well as a shorter hospital stay and recovery.

    Robot-assisted radical cystectomy (RARC) has rapidly penetrated the field of urology since its inception in 2003. Several observational studies, retrospective reports, and three randomized controlled trials (RCT) have preliminarily demonstrated the safety and efficacy of (RARC). Additionally, results from the RAZOR RCT will be available in 2016-2017 to better substantiate the use of (RARC). PMID:26310514

  6. Ovarian cystectomy in endometriomas: Combined approach

    2014-01-01

    Endometrioma is one of the most frequent adnexal masses in the premenopausal population, but the recommended treatment is still a subject of debate. Medical therapy is inefficient and can not be recommended in the management of ovarian endometriomas. The general consensus is that ovarian endometriomas larger than 4 cm should be removed, both to reduce pain and to improve spontaneous conception rates. The removal of ovarian endometriomas can be difficult, as the capsule is often densely adherent. While the surgical treatment of choice is surgical laparoscopy, for conservative treatment, the preferred method is modified combined cystectomy. Cystectomy can be destructive for the ovary, whereas ablation may be incomplete, with a greater risk of recurrence. To the best of our knowledge, the modified combined technique seems to be more efficient in the treatment of endometriomas. PMID:25317047

    2015-01-01

    Radical cystectomy (RC) with pelvic lymph node dissection (PLND) followed by urinary diversion is the treatment of choice for muscle-invasive bladder cancer (BC) and non-invasive BC refractory to transurethral resection of the bladder (TUR-B) and/or intravesical instillation therapies. Since the morbidity and possible mortality of this surgery are relevant, care must be taken in the preoperative selection of patients for the various organ-sparing procedures (e.g., bladder-sparing, nerve sparing, seminal vesicle sparing) and various types of urinary diversion. The patient’s performance status and comorbidities, along with individual tumor characteristics, determine possible surgical steps during RC. This individualized approach to RC in each patient can maximize oncological safety and minimize avoidable side effects, rendering ‘standard’ cystectomy a surgery of the past. PMID:26813034

    Radical cystectomy and orthotopic reconstruction significant morbidity and mortality despite advances in minimal invasive and robotic technology. In this review, we will discuss early and late complications, as well as describe efforts to minimize morbidity and mortality, with a focus on ileal orthotopic bladder substitute (OBS). We summarise efforts to minimize morbidity and mortality including enhanced recovery as well as early and late complications seen after radical cystectomy and OBS. Centralisation of complex cancer services in the UK has led to a fall in mortality and high volume institutions have a significantly lower rate of 30-day mortality compared to low volume institutions. Enhanced recovery pathways have resulted in shorter length of hospital stay and potentially a reduction in morbidity. Early complications of radical cystectomy occur as a direct result of the surgery itself while late complications, which can occur even after 10 years after surgery, are due to urinary diversion. OBS represents the ideal urinary diversion for patients without contraindications. However, all patients with OBS should have regular long term follow-up for oncological surveillance and to identify complications should they arise. PMID:26697063

    Purpose To determine the impact of preoperative nutritional status on the development of surgical complications following cystectomy using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Methods We performed a retrospective review of the NSQIP 2005–2012 Participant Use Data Files. ACS-NSQIP collects data on 135 variables, including pre- and intraoperative data and 30-day post-operative complications and mortality on all major surgical procedures at participating institutions. Preoperative albumin (<3.5 or >3.5 g/dl), weight loss 6 months before surgery (>10%), and BMI were identified as nutritional variables within the database. The overall complication rate was calculated and predictors of complications were identified using multivariable logistic regression models. Results 1,213 patients underwent cystectomy for bladder cancer between 2005–2012. The overall 30-day complication rate was 55.1% (n=668). While 14.7% (n=102) had a preoperative albumin <3.5 g/dL, 3.4% had >10% weight loss in the 6 months prior to surgery, and the mean BMI was 28 kg/m2. After controlling for age, sex, medical comorbidities, medical resident involvement, operation year, operative time and prior operation, only albumin <3.5g/dl was a significant predictor of experiencing a postoperative complication (p=0.03). This remained significant when albumin was evaluated as a continuous variable (p=0.02) Conclusions Poor nutritional status measured by serum albumin is predictive of an increased rate of surgical complications following radical cystectomy. This finding supports the importance of preoperative nutritional status in this population and highlights the need for the development of effective nutritional interventions in the preoperative setting.

    Open radical cystectomy (ORC) is the current gold standard treatment for muscle invasive bladder cancer. As surgeons become more proficient in minimally invasive and robotic surgical techniques, the number of patients undergoing robotic-assisted radical cystectomy (RARC) is increasing. Although minimally invasive methods are on the rise, research that critically compares open surgery with robotic methods is limited. In this review, we surveyed and appraised the current literature comparing ORC and RARC with regards to perioperative, functional, and oncologic outcomes in order to distinguish the benefits and disadvantages of each method. Here we report that RARC is associated with several perioperative advantages over ORC such as lower estimated blood loss and transfusion rate, and possibly faster gastrointestinal recovery, lower narcotic requirement, and shorter length of stay. ORC is less costly and permits less time in the operating room. Recent data suggests that there is no difference between ORC and RARC when comparing urinary continence and postoperative quality of life. Moreover, ORC and RARC are both associated with similar rates of obtaining positive surgical margins, lymph node yield, and recurrence. However, RARC patients had an increased likelihood of having distant metastases to extrapelvic lymph nodes and the peritoneum. At this point, it is unclear if ORC or RARC has superior patient outcomes, and more research is needed to ascertain management-altering conclusions. PMID:27326405

    The obese patient undergoing radical cystectomy faces a unique set of challenges. We present the case of a 68-year-old gentleman who presented to our institution with Bacillus Calmette-Guerin refractory disease, a body mass index of 38.5, and a large pannus. The present paper describes our technique for performing radical cystectomy with ileal conduit urinary diversion and concomitant panniculectomy. We discuss the impact of obesity on patients undergoing radical cystectomy and how this may be mitigated by panniculectomy. PMID:27195168

    The importance of patient selection for quality outcomes following radical cystectomy is critical. Clinical staging is one of the key elements necessary for patient selection, and staging relies on accurate preoperative imaging. Many imaging modalities are available and have been utilized for preoperative staging with published operating characteristics. In this update, we review recently published literature for advances in preoperative imaging prior to radical cystectomy. PMID:27432379

    Tracheal stenosis is a serious, life-threatening disease with an increasing tendency. The number of complicated tracheal lesions, where resection and anastomosis can not be performed, still increases and the situation requires solution by endoprosthesis. Consequent the management of such complicated obstructive tracheal lesions is individual and time-consuming. The main objective of this study is to review the single institution experience with central airways stenosis treatment and to define the role of endotracheal stenting in tracheal reconstruction surgery. This study presents the retrospective analysis of tracheal stenosis reconstruction by means of our own modification of Montgomery T-tube. (Tab. 3, Fig. 3, Ref. 12.) PMID:15543848

    Objective: We analyzed the effect of previous abdominal surgery (PAS) on consecutive patients who underwent robot-assisted radical cystectomy (RARC). Materials and Methods: From 2005 to 2008, 73 patients at a single institution underwent RARC with bilateral extended pelvic lymph node dissection and urinary diversion. Lysis of adhesions was performed robotically and laparoscopically. Records were reviewed to assess the impact of PAS on operative outcomes and complications up to 3 months after surgery. Results: Of the 73 patients, 37 (51%) had undergone PAS. Of these 37, 6 (16%) had PAS above the umbilicus, and 31 (84%) had surgery either above and below or strictly below the umbilicus. Patients with PAS were significantly older than those without (P<0.01). No statistically significant difference was seen with respect to blood loss, transfusion requirement, operative time, lysis of adhesion time, length of ICU stay, overall hospital stay, or the need for reoperation between patients with PAS and those without PAS. The overall postoperative complication rate was higher in the group with PAS (P=0.04). Lymph node yield was higher in patients without PAS (P<0.01). Patients with PAS below the umbilicus had a significantly longer hospital stay than patients with surgery strictly above the umbilicus had (P=0.01). Whether individuals had previously undergone single or multiple surgeries had no significance. Conclusion: Robot-assisted radical cystectomy in patients with a history of previous surgery may carry a higher risk for postoperative complications. However, previous operations do not appear to affect the likelihood of a safely completed robotic operation. Patients should be counseled about their risk of obstacles after surgery. PMID:19793483

    Introduction: We instituted a ketamine-predominant analgesic regimen in the peri- and postoperative periods to limit the effects of narcotic analgesia on bowel function in patients undergoing radical cystectomy. The primary end points of interest were time to return of bowel function, time to discharge, and efficacy of the analgesic regimen. Methods: We performed a retrospective chart review of patients undergoing robotic-assisted laparoscopic cystectomy (RARC) with urinary diversion by a single surgeon at our institution from January 1, 2011 to June 30, 2012. Patients receiving the opioid-minimizing ketamine protocol were compared to a cohort of patients undergoing RARC with an opioid-predominant analgesic regimen. Results: In total, 15 patients (Group A) were included in the ketamine-predominant regimen and 25 patients (Group B) in the opioid-predominant control group. Three patients (19%) in Group A discontinued the protocol due to ketamine side effects. The mean time to bowel movement and length of stay in Group A versus Group B was 3 versus 6 days (p < 0.001), and 4 versus 8 days, respectively (p < 0.001). Group A patients received an average of 13.0 mg of morphine versus 97.5 mg in Group B (p < 0.001). Conclusions: Patients who received our ketamine pain control regimen had a shorter time to return of bowel function and length of hospitalization after RARC. Our study has its limitations as a retrospective, single surgeon, single institution study and the non-randomization of patients. Notwithstanding these limitations, this study was not designed to show inferiority of one approach, but instead to show that our protocol is safe and efficacious, warranting further study in a prospective fashion.

  17. Current Status of Robot-Assisted Radical Cystectomy: What is the Real Benefit?

    2015-09-01

    In recent years, robot-assisted radical cystectomy has received attention worldwide as a useful procedure that helps to overcome the limitations of open radical cystectomy. We compared the surgical technique, perioperative and oncological outcomes, and learning curve of robot-assisted radical cystectomy with those of open radical cystectomy. The indications for robot-assisted radical cystectomy are identical to those of open radical cystectomy. Relative contraindications are due to patient positioning in the Trendelenburg position for long periods. Urinary diversion is performed either extracorporeally with a small skin incision or intracorporeally with a totally robotic-assisted maneuver. Accordingly, robot-assisted radical cystectomy can be performed safely with an acceptable operative time, little blood loss, and low transfusion rates. The lymph node yield and positive surgical margin rate were not significantly different between robot-assisted radical cystectomy and open radical cystectomy. The survival rates after robot-assisted radical cystectomy are estimated to be similar to that after open radical cystectomy. However, the recurrence pattern is different between robot-assisted radical cystectomy and open radical cystectomy, i.e., extrapelvic lymph node recurrence and peritoneal carcinomatosis were more frequently found in patients who underwent robot-assisted radical cystectomy than in those who underwent open radical cystectomy. Further validation is necessary to prove the feasibility of oncological control. A steep learning curve is one of the benefits of the new technique. The experience of only 50 robot-assisted radical prostatectomies is a minimum requirement for performing feasible robot-assisted radical cystectomy, and surgeons who have performed only 30 surgeries can reach an acceptable level of quality for robot-assisted radical cystectomy.

    A systematic review of the literature on perioperative morbidity (POM) was done using Medline software with a combination of keywords like mortality, morbidity, and complications. In addition, we review the analysis of our hospital data of 261 Radical cystectomies (RCs) performed in an 11-year period and our latest clinical pathway for RC. Age range in our series was 50 to 81 years with 240 males and 21 females. RCs were performed by intraperitoneal method in 172 patients and by our extraperitoneal (EP) method in 89 patients. Urinary diversion was ileal conduit in 159 patients and neobladder in 102 patients. Blood loss ranged between 500 and 1500 ccs. Postoperative mortality occurred in eight patients (3%). Among the other early post-op complications, major urinary leak was seen in nine and minor in 11, requiring PCN in five patients and reoperation in four patients. Bowel leak or obstruction was seen in six and four patients, respectively, requiring reoperation in six patients. EP RC in our series showed some benefit in reduction of POM. The mortality of RC has declined but the POM still ranges from 11 to 68%, as reported in 23 series (1999-2008) comprising of 14 076 patients. Various risk factors leading to POM and some corrective measures are discussed in detail. However, most of these series are retrospective and lack standard complication reporting, which limits the comparison of outcomes. Various modifications in open surgical technique and laparoscopic and Robotic approaches are aimed at reduction in mortality and POM of RC. PMID:21814314

  19. Incidence of Venous Thromboembolism in Patients Undergoing Major Hip Surgeries at a Single Institution: A Prospective Study

    2016-01-01

    Background: Venous thoromboembolism (VTE) is one of the most significant complications after hip surgeries. Many studies have been reported about the incidence of VTE after THA, but a small number of reports were found concerning Periacetabular osteotomy, Revision THA and Surgery for hip fracture postoperatively. Furthermore, there exists no comparative study of the incidence of VTE among major hip surgeries at a single institution. We reported the incidence of VTE among hip surgeries performed at a single institution. Methods: A total of 820 Hip surgeries were performed at same institution. The procedures included 420 hips that underwent primary total hip arthroplasties (THA), 91 revision or removal of total hip arthroplasties (Revision THA), 144 periacetabular osteotomy (PAO) and 165 surgery for hip fracture (SHF) between 2006 and 2012. VTE was detected by Multidetector computed tomography (MDCT) that scanned 768 cases and by ultrasound that scanned 52cases postoperative 10-14 days. Results: The overall incidence of VTE was 12.2% (100 of 820). The incidence of VTE after THA was 13.1% (55 of 420), Revision THA was 13.2% (12 of 91), PAO was 2.1% (3 of 144) and SHF was 18.1% (30 of 165). The incidence of VTE was significantly higher in SHF than in PAO. Conclusion: This data indicates that the incidence of VTE after PAO is significantly lower than SHF and relatively lower than THA and Revision THA. A younger age and non-invasion of the bone marrow of the femur may have affected the result. Prophylaxis therapy was effective especially on SHF. PMID:27499823

    Ureteroarterial fistulas (UAFs) are defined as an abnormal communication between one of the major arteries and the ureter. Urologists most frequently encounter iatrogenic fistulas occurring in patients with a history of pelvic extirpative surgery, chronic ureteral catheterization, and history of pelvic radiation. We present two cases of UAFs in patients with no history of prior radiation, who underwent open radical cystectomy and robot-assisted radical cystectomy with intracorporeal ileal conduit. Both patients developed postoperative ureteroileal anastomotic leaks that were managed with indwelling ureteral catheters. Furthermore, both patients were having left-sided UAF after presenting with nonlife threatening gross hematuria, which became brisk and pulsatile during ureteral stent exchange. Endovascular stenting was performed in both patients with resolution of hemorrhage and full recovery. In one patient, nephrostomy tubes were placed and ureteral catheters were removed; the second patient was managed with continued ureteral catheterization without further episodes of hematuria.

    Squamous dysplasia of the urinary bladder is uncommon and may represent a precursor to invasive squamous cell carcinoma. Though significant focus has been devoted to squamous differentiation in invasive bladder cancer, relatively little attention has been given to squamous dysplasia. We methodically reviewed microscopic slides from a consecutive cystectomy series at our institution (n = 303; 2001-2014), with special attention given to squamous dysplasia and squamous differentiation within association invasive carcinoma. Of these 303 cases, 3% (9 cases) had squamous dysplasia. The majority (89%; 8/9) had a similar morphological appearance to squamous dysplasia of the head and neck (ie, cytological atypia, architectural disturbances, and abnormal keratinization). Invasive carcinoma was present in 230 of the cystectomy cases. Of these 230 cases with invasive carcinoma, 4% (8 cases) also had squamous dysplasia. The invasive carcinoma had evidence of squamous differentiation in all cases with concurrent squamous dysplasia. Concurrent flat urothelial carcinoma in situ was present in 3 of the 8 cases with both invasive carcinoma and squamous dysplasia. Squamous dysplasia was not associated with clinical outcomes data, including death from bladder cancer and bladder cancer recurrence. The data from this study indicate that squamous dysplasia is uncommon in the cystectomy setting, frequently has the morphology of head and neck dysplasia, and is often associated with invasive carcinoma with squamous differentiation.

    Introduction In 2008, our department introduced a modified technique of laparoscopic radical cystectomy in which the prostatic capsule is spared in selected patients with bladder cancer. The different series published are mostly using the standard open procedure. The aim of this study is to describe this technique using the laparoscopic approach and present our preliminary results. Material and methods This study includes 20 patients selected by clinical analysis and imaging criteria operated using laparoscopic radical cystectomy with prostate capsule sparing at our department in the period between 2008 and 2012. Results Patient mean age was 58 years. Mean operative time was 390 minutes. Median follow-up was 36 months. No patient had bladder cancer recurrence. Only one patient died of disease progression, as the pathological findings was a pT3 pN1 Mx. Mean PSA before surgery: 1.3 ng/ml (03–2), mean PSA after surgery 1.0 ng/ml (0.08–1.7). No patients had prostate cancer recurrence. Satisfactory daytime and night-time continence was achieved. 90% of patients have sexual function preserved. Conclusions Prostate-sparing radical cystectomy remains one of the most controversial topics in urology today. The laparoscopic approach could be an alternative to conventional radical cystoprostatectomy in well selected patients, done in experienced institutions in order to find better functional results, with a low disease progression and recurrence rate.

    Introduction: Radical cystectomy is the gold-standard treatment for muscle-invasive and refractory nonmuscle-invasive bladder cancer. We describe our technique for robotic radical cystectomy (RRC) and intracorporeal urinary diversion (ICUD), that replicates open surgical principles, and present our preliminary results. Materials and Methods: Specific descriptions for preoperative planning, surgical technique, and postoperative care are provided. Demographics, perioperative and 30-day complications data were collected prospectively and retrospectively analyzed. Learning curve trends were analyzed individually for ileal conduits (IC) and neobladders (NB). SAS® Software Version 9.3 was used for statistical analyses with statistical significance set at P < 0.05. Results: Between July 2010 and September 2013, RRC and lymph node dissection with ICUD were performed in 103 consecutive patients (orthotopic NB=46, IC 57). All procedures were completed robotically replicating the open surgical principles. The learning curve trends showed a significant reduction in hospital stay for both IC (11 vs. 6-day, P < 0.01) and orthotopic NB (13 vs. 7.5-day, P < 0.01) when comparing the first third of the cohort with the rest of the group. Overall median (range) operative time and estimated blood loss was 7 h (4.8-13) and 200 mL (50-1200), respectively. Within 30-day postoperatively, complications occurred in 61 (59%) patients, with the majority being low grade (n = 43), and no patient died. Median (range) nodes yield was 36 (0-106) and 4 (3.9%) specimens had positive surgical margins. Conclusions: Robotic radical cystectomy with totally ICUD is safe and feasible. It can be performed using the established open surgical principles with encouraging perioperative outcomes. PMID:25097317

    The patient who undergoes radical cystectomy requires a urinary diversion which will significantly impact on his everyday life. He will have to choose with his surgeon between three different types of diversions that enable urine to flow out of his body adequately. Hence, preoperative information is of paramount importance. The team providing it needs an iconographic support, unfortunately not readily available. In order to clearly explain to the patient the various types of diversions that he may benefit from, their everyday care and to have him/her share the experiences of previous patients, we have elaborated a multi-disciplinary information sequence associated with the creation of video support.

    Objective This study was performed to assess our clinical experience with single-port access (SPA) laparoscopic cystectomy and myomectomy and the surgical outcomes of those procedures at our institution. Methods The authors evaluated the surgical outcomes of SPA laparoscopic cystectomy in 293 patients and SPA laparoscopic myomectomy in 246 patients. The surgical outcomes comprised operation time, the amount of blood loss during the operation, the change in hemoglobin (before and after the operation), the change in hematocrit (before and after the operation), switching to the multi-port access method, complications, transfusions, and the duration of the postoperative hospital stay. Results The Pearson correlation coefficient and the Spearman correlation coefficient between the operation time and the amount of blood loss were 0.312 and 0.321 for SPA laparoscopic cystectomy, respectively, and 0.706 and 0.674 for SPA laparoscopic myomectomy, respectively. The drops in hemoglobin and hematocrit were 1.33±0.78 g/dL and 4.14%±2.45%, respectively, in SPA laparoscopic cystectomy, while the corresponding figures were 1.34±1.13 g/dL and 4.17%±3.24% in SPA laparoscopic myomectomy, respectively. Conclusion This study reported the surgical outcomes of SPA laparoscopic cystectomy and myomectomy and compared them to previously published findings on traditional laparoscopic cystectomy and myomectomy. No significant differences were found in the surgical outcomes between SPA and traditional laparoscopic cystectomy and myomectomy. PMID:27104157

    To summarise the current literature on the diagnosis and management of urethral recurrence (UR) after radical cystectomy (RC), as UR after RC is rare but associated with high mortality. With the recently increased use of orthotopic bladder substitution and the questionable benefit of prophylactic urethrectomy, identification of patients at high risk of UR, management of the remnant urethra, and treatment of UR become critical questions. A review of the PubMed database from 1980 to 2014 was performed to identify studies evaluating recurrent urothelial cancer of the urethra after RC. The search terms used included 'urethral recurrence', 'cystectomy' or 'cystoprostatectomy'. Selected studies provided information on the type of urinary diversion performed, the incidence of UR, and the time to UR. Incidence of UR after RC ranges from 1% to 8% with most recurrences occurring within the first 2 years after surgery. Increased risk of UR is associated with involvement of the prostate, tumour multifocality, bladder neck involvement, and cutaneous diversion. The median overall survival after UR ranges from 6 to 54 months and the 5-year disease-specific survival after UR is reported to be between zero and 83%. UR remains a relatively rare event. Current literature suggests that urethral wash cytology may be useful in patients with intermediate- to high-risk of recurrence to enable early detection of non-invasive disease, which may be amenable to conservative therapy before urethrectomy.

    Open radical cystectomy (ORC) remains the gold standard for treatment of muscle-invasive bladder cancer and certain cases of high-risk noninvasive bladder cancer. However, ORC is associated with significant morbidity, and there is promise of improved outcomes with the emergence of minimally invasive surgery. Because of the increased adoption of robotic radical cystectomy (RRC), we sought to review the current literature on the robotic approach. We explored the surgical techniques, perioperative and postoperative complications, oncologic and functional outcomes, and quality of life of patients with RRC versus ORC. Current data appear to favor RRC in perioperative outcomes and patient recovery, although RRC continues to be associated with longer surgical times and higher costs. Oncologic data are also promising, however data on long-term oncologic outcomes are insufficient. To date, there is evidence of similar functional outcomes between RRC and ORC continence, but there is a paucity of rigorous, standardized studies on health-related quality of life for continent versus incontinent diversion. Even as use of RRC steadily grows, there is a lack of consensus on the type of approach and urinary diversion that is optimal. We assessed the influence of surgeon experience on the totally intracorporeal urinary diversion and its feasibility to be widely adopted. We aimed to answer the question of whether there are significant benefits to RRC, and furthermore, of the effect of the approach on the choice of urinary diversion. PMID:26234169

    Background: Centralization of cystectomy treatment for bladder cancer, while associated with improved outcomes, may impose geographic barriers to care. However, whether this effect may be counterbalanced by an increased number of high volume centers has not previously been explored. Objective: To characterize changes in geographic disparities to high volume cystectomy centers over time. Methods: Data on all inpatient admissions for cystectomy in New York State (NYS) from 1997–2011 was obtained from the Department of Health. Using these data, we classified hospitals according to cystectomy volume and measured patient distance traveled to a cystectomy center. Population weights, from the US Census, were used to describe changes in minimum travel distance to high- or very high-volume (HV/VHV) facilities across the NYS population. Results: Bladder cancer patients underwent cystectomies at 195 hospitals during the study period. In 1997–2001, eleven HV/VHV facilities accounted for 37.5% of all cystectomies, while sixteen HV/VHV hospitals accounted for 71.5% of all procedures during 2007–2011. Median distance traveled by cystectomy patients to all hospitals increased from 9.6 to 14.4 miles in 1997–2001 to 2007–2011, respectively. In the same time span, the median travel distance for the NYS population to a HV/VHV center decreased by 1.9 and 9.4 miles at the median and 75th percentile, respectively. Conclusions: Our findings demonstrate a complicated relationship between centralization and geographic access. While centralization has led to a decrease in overall access to cystectomy facilities, the process simultaneously improved access to high volume centers. PMID:27500199

    Objective: To investigate the merits and 10 year follow-up results of two kinds of cutaneous ureterostomy operation in patients with the radical cystectomy. Methods: We retrospective analyzed the information of patients underwent radical cystectomy in the past 10 years, comparing and analyzing the consequence of application value, early and long-term follow-up results using two kinds of cutaneous ureterostomy in patients with radical cystectomy. Results: Unilateral ureteral cutaneous ureterostomy didn’t increase patients’ early and long-term complications, and improved the patient’s life satisfaction. Conclusion: The unilateral cutaneous ureterostomy didn’t increase postoperative complications in patients, while improving the patient’s life satisfaction. Unilateral ureteral cutaneous ureterostomy is an important complement to urinary diversion after radical cystectomy and the best choice for cutaneous ureterostomy. PMID:26550423

    Between January 1979 and March 1983, 63 consecutive patients underwent cystectomy and urinary diversion for primary carcinoma of the bladder at Roswell Park Memorial Institute (RPMI). Fifty-five patients had transitional cell carcinoma, 6 squamous cell carcinoma and 2 adenocarcinoma of the bladder. Twelve patients with bladder cancer were found to have adenocarcinoma of the prostate on the pathological specimen. Preoperative radiation was given to 41 patients. Thirty-six patients received 4000 rads preoperatively followed by radical cystectomy, 5 patients received 2000 rads. Thirteen patients received 6000 rads as curative treatment and underwent salvage cystectomy and colon conduit because of failure. There was no operative mortality. Severe complications in the early postoperative period occurred in 19 instances, some patients having more than one complication. Late complications necessitating surgical correction occurred in 5 patients. Although radical cystectomy is effective in controlling the local disease, most patients still died of metastatic transitional cell carcinoma. PMID:6483919

    Diagnosis of appendicitis, particularly in young women, may be challenging. In case of abdominal pain in the postoperative period of laparoscopic surgery, one should not only think of complications such as bleeding and injury of the bowel but also such as acute appendicitis. We report a case of a 26-year-old female patient with a post-laparoscopic acute appendicitis with appendicolithiasis 3 days after a laparoscopic ovarian cystectomy during which the appendix appeared inconspicuous. Appendicitis after gynecologic laparoscopy is a rare but potentially dangerous condition. One should consider the possibility of a postoperative appendicitis in case of an acute abdomen after laparoscopic surgery. Further studies might be of value to re-evaluate incidental appendectomy especially in cases of appendicolithiasis. PMID:27103602

    Prior work documented that surgical removal of approximately 70% of the bladder (subtotal cystectomy) in 12-week-old female rats induced complete functional regeneration of the bladder within 8 weeks. To determine whether animal age affects bladder regeneration, female F344 rats aged 12 weeks (young) and 12 months (old) underwent subtotal cystectomy, and then were evaluated from 1 to 26 weeks after subtotal cystectomy. At 26 weeks after subtotal cystectomy, bladder capacity in young animals was indistinguishable from that in age-matched controls, but bladder capacity in old animals was only approximately 56% of that in age-matched controls. There was no detectable difference in residual volume among treatment groups, but the diminished regeneration in old animals was associated with a corresponding increase in the ratio of residual volume to micturition volume. The majority of old animals exhibited evidence of chronic kidney damage after subtotal cystectomy. Maximal contraction of bladder strips to electrical field stimulation, as well as activation with carbachol, phenylephrine, and KCl, were lower in old than in young animals at 26 weeks after subtotal cystectomy. Immunostaining with proliferating cell nuclear antigen and Von Willebrand factor revealed delayed and/or diminished proliferative and angiogenic responses, respectively, in old animals. These results confirm prior work and suggest that multiple mechanisms may contribute to an age-related decline in the regenerative capacity of the bladder. PMID:24012523

    Objective To characterise the surgical feasibility and outcomes of robot-assisted radical cystectomy (RARC) for pathological T4 bladder cancer. Patients and Methods Retrospective evaluation of a prospectively maintained International Radical Cystectomy Consortium database was conducted for 1118 patients who underwent RARC between 2003 and 2012. We dichotomised patients based on pathological stage (≤pT3 vs pT4) and evaluated demographic, operative and pathological variables in relation to morbidity and mortality. Results In all, 1000 ≤pT3 and 118 pT4 patients were evaluated. The pT4 patients were older than the ≤pT3 patients (P = 0.001). The median operating time and blood loss were 386 min and 350 mL vs 396 min and 350 mL for p T4 and ≤pT3, respectively. The complication rate was similar (54% vs 58%; P = 0.64) among ≤pT3 and pT4 patients, respectively. The overall 30-and 90-day mortality rate was 0.4% and 1.8% vs 4.2% and 8.5% for ≤pT3 vs pT4 patients (P < 0.001), respectively. The body mass index (BMI), American Society of Anesthesiology score, length of hospital stay (LOS) >10 days, and 90-day readmission were significantly associated with complications in pT4 patients. Meanwhile, BMI, LOS >10 days, grade 3–5 complications, 90-day readmission, smoking, previous abdominal surgery and neoadjuvant chemotherapy were significantly associated with mortality in pT4 patients. On multivariate analysis, BMI was an independent predictor of complications in pT4 patients, but not for mortality. Conclusions RARC for pT4 bladder cancer is surgically feasible but entails significant morbidity and mortality. BMI was independent predictor of complications in pT4 patients. PMID:24219170

    Objective. To report our contemporary experience with partial cystectomy after neoadjuvant chemotherapy. Patients and Methods. Retrospective review of patients who underwent neoadjuvant chemotherapy and partial cystectomy for urothelial cell carcinoma of the bladder at Memorial Sloan Kettering Cancer Center from 1995 to 2013. Log-rank test and Cox regression models were used to analyze variables possibly associated with recurrence-free, advanced recurrence-free (free from recurrence beyond salvage with intravesical therapy or radical cystectomy), and overall survival. Results. All 36 patients had a solitary tumor <5 cm in size. Twenty-one patients (58%) achieved cT0 following neoadjuvant chemotherapy with 7 (33%) having residual disease at PC. At last follow-up, 19 (53%) patients had recurrence, 15 (42%) had advanced recurrence, 10 (28%) died of disease, and 22 (61%) maintained an intact bladder. Median follow-up of those who were with no evidence of disease was 17 months. On univariable analysis, after neoadjuvant chemotherapy positive nodes on imaging and positive surgical margin at partial cystectomy were both associated with worse recurrence-free, advanced recurrence-free, and overall survival. Five-year recurrence-free, advanced recurrence-free, and overall survival were 28%, 51%, and 63%, respectively. Conclusion. Partial cystectomy following neoadjuvant chemotherapy provides acceptable oncologic outcomes in highly selected patients with muscle-invasive bladder cancer.

    Despite a known survival benefit, gross underutilization of radical cystectomy in the treatment of muscle-invasive bladder cancer (MIBC) continues. The leading hypothesis for these low utilization rates is access to care, with barriers that can be classified into 3 categories: acceptability, availability, and affordability. Acceptability is highlighted by patient miseducation, fears, and cultural beliefs, which can lead to poor treatment decisions and emphasizes the need for decision-making research for MIBC. Availability is defined by structural barriers such as facility type and physician access. Understanding and improving differences in treatment among community vs. academic centers may improve access to cystectomy among patients who are treated locally. Affordability is marked by both direct (e.g., hospital) and indirect (e.g., travel) costs, with insurance type and travel distance notably affecting cystectomy receipt. Understanding the interplay of the "3 A's" that comprise cystectomy access to care is needed before we can successfully increase utilization of cystectomy in the vulnerable MIBC population.

    Objective This study was conducted to compare the surgical outcomes between two-port access and four-port access laparoscopic ovarian cystectomy. Methods Four hundred and eighty nine patients who had received two-port access laparoscopic ovarian cystectomy (n=175) and four-port access laparoscopic ovarian cystectomy (n=314) in Chungnam National University Hospital from January 2009 to August 2012 were analyzed retrospectively. The data were compared between the bilaterality of the cysts and cyst diameter of less than 6 cm and 6 cm or more. Results There were no significant differences in patient's age, parity, body weight, body mass index and history of previous surgery between the two-port and four-port access laparoscopy group. Bilaterality of ovarian cysts was more in fourport access laparoscopy group (13.7% vs. 32.5%, P=0.000). There were no significant differences in operation time, hemoglobin change, hospital stay, adhesiolysis, transfusion, and insertion of hemo-vac between the two-port and four-port access laparoscopy group for size matched compare. However additional analgesics were more in four-port access laparoscopy group for unilateral ovarian cystectomy. Conclusion Two-port access laparoscopic surgery was feasible and safe for unilateral and bilateral ovarian cystectomy compare with four-port access laparoscopic surgery. PMID:25264528

    Robotic-assisted ureteral reimplantations were performed on 3 patients at a single institution, 2 with Boari flap and psoas hitch and 1 with psoas hitch alone. These were for urothelial carcinoma of the distal ureter, ureteral obstruction caused by distal ureteral endometriosis, and ureteral transaction during gynecologic surgery. We used intraoperative ureteroscopy to confirm tumor margins as well as a simple technique for retrograde placement of transvesicle wire prior to ureteral anastomosis. Surgery and recovery were uneventful. This illustrates that robotic-assisted ureteral reimplantation with Boari flap and psoas hitch is a safe and viable approach for ureterovesicle reconstruction.

    Our goal is to describe our experience in the difficulties encountered during radical cystectomy for muscle invasive bladder cancer in patients with contemporary pelvic kidney. Two patients with muscle invasive bladder cancer and contemporary pelvic kidney were subjected to radical cystectomy and extended lymphadenectomy with conversion to an ileal pouch. In both cases, lymphadenectomy was the first step after entering the true pelvis. In order to proceed to the cystoprostatectomy, careful dissection of the ectopic renal vessels and proper mobilization of the kidney were performed. In both cases, an ileal pouch was our choice. The pelvic kidney is the most common sight of renal ectopia. The etiology is the aborted ascent of the fetal kidney from its initial position in the pelvis. This is the first case series describing radical cystectomy for muscle invasive urothelial carcinoma of the bladder in patients with a pelvic kidney. PMID:24307907

    Cavernous Hemangioma of the Bladder (CHB) is benign and rare lesions. Clinical presentation has no pathognomonic signs although gross painless hematuria is the most frequent complain. CHB is suspected by cystoscopy and radiologic findings and confirmed by pathologic examinations. Management is controversial due to the bleeding risk of this highly vascularized lesion. Partial cystectomy is the treatment of choice for surgically accessible lesions. However, it appears that small lesions could be treated using transurethral resection. Since CHB is a rare case, we report another case treated successfully with a partial cystectomy associated with an augmentation cystoplasy. PMID:26889312

    Left ventricular assist device (LVAD) is an option for the surgical management of severe heart failure, and radical cystectomy remains the standard of care for muscle-invasive bladder cancer. Given a complicated population in terms of comorbidities and management for patients with an LVAD, there is little experience with major urologic procedures, which require balancing the benefits of surgery with considerable perioperative risks. We report our experience performing the first radical cystectomy with ileal conduit in a patient with an LVAD and muscle-invasive bladder cancer. PMID:26290767

    Objective To stratify patients with bladder cancer into homogeneous risk groups according to statistically significant differences found in PFS (progression-free survival). To identify those patients at increased risk of progression and to provide oncological follow-up according to patient risk group. Materials and Methods A retrospective study of 563 patients treated with radical cystectomy (RC). In order to determine which factors might predict bladder tumour progression and death, uni- and multivariate analyses were performed. The risk groups were identified according to “inter-category” differences found in PFS and lack of differences, thus revealing intra-category homogeneity. Results Median follow up time was 37.8 months. Recurrence occurred in a total of 219 patients (38, 9%). In 63% of cases this was distant recurrence. Only two variables retained independent prognostic value in the multivariate analysis for PFS: pathological organ confinement and lymph node involvement. By combining these two variables, we created a new “risk group” variable. In this second model it was found that the new variable behaved as an independent predictor associated with PFS. Four risk groups were identified: very low, low, intermediate and high risk: • Very low risk: pT0 N0 • Low risk: pTa, pTis, pT1, pT2 and pN0 • Intermediate risk: pT3 and pN0 • High risk: pT4 N0 or pN1-3. Conclusions We retrospectively identified 4 risk groups with an independent prognostic value for progression-free survival following RC. Differences in recurrence patterns after RC between risk groups have led us to set different intervals in monitoring for cancer. PMID:25928508

    Abstract Background: Radical cystectomy (RC) carries a high complication rate, including post-operative ileus. Alvimopan is an FDA approved peripherally acting μ-opioid receptor antagonist that has shown favorable results for improved recovery of gastro-intestinal function resulting in decreased hospital length of stay. Many enhanced recovery pathways (ERP) have been published demonstrating improved outcomes with decreased hospital stay and morbidity. Objective: We evaluated the addition of alvimopan to an ERP in patients undergoing RC. Methods: Patients undergoing RC at our institution during the implementation phase of alvimopan to our established ERP were retrospectively reviewed. Effect of alvimopan as it related to the use of nasogastric tubes, time to initiation of regular diet, and length of hospital stay was assessed using Chi-squared and Student’s T-tests. Linear regression was performed for univariate analysis and binary logistic regression was performed as a multivariate assessment of the effect of alvimopan. Results: Between July 2011 and January 2013, 80 patients were identified who underwent RC under the ERP (34 alvimopan and 46 standard care). Age, sex, neoadjuvant chemotherapy, surgical technique (open vs. robotic), and type of urinary diversion were not different between groups. Alvimopan was associated with a reduction in mean time to regular diet (5.3 vs 4.1 days, p <  0.01) and a reduction in mean length of hospital stay (6.9 vs 5.7 days, p = 0.01). After controlling for other variables, alvimopan usage predicted for shorter time to regular diet and total hospital stay. Conclusions: Alvimopan may help to improve time to regular diet and decrease hospital stay in patients on an enhanced recovery pathway. PMID:27398398

We present our experience and believe it is the first Canadian reported series with this technique. Methods: This is a case series of 4 patients, who underwent total RARC, pelvic lymphadenectomy and creation of an intra-corporeal ileal neobladder. Surgical technique is described and perioperative variables, pathologic data, and complication rates are reported. Results: The mean patient age was 61.8 and the mean body mass index was 27.01 kg/m2. The mean operative time, estimated blood loss, time to full diet and length of stay were 522.8 minutes (standard deviation [SD] 74.5), 237.5 mL (SD 47.9), 9 days (range: 3–24) and 12.8 days (range: 6–31), respectively. All patients completed postoperative functional evaluation showing a mean neobladder capacity of 575 cc (range: 500–720). Surgical margins and pathological nodal status were negative in all patients with no evidence of disease recurrence or progression on follow-up. Three of the 4 patients suffered a complication within 90 days, with one occurring later in the first year. All early complications were Clavien grade I–II (grade I [n = 1]; grade II [n = 2]) and the later complication was grade IIIa. The mean follow-up was 632 days (range: 562–730). The limitation of our study is its small sample size with highly selected patients to compensate for the learning experience. The follow-up is short; however, the outcomes are comparable to early experiences reported at other institutions. Conclusions: In our initial experience, RARC with total intracorporeal neobladder formation is safe. We expect that with experience the expense of robotic surgery can be compensated with early ambulation and shorter stay. PMID:25844107

    Introduction: We sought to determine the patient and provider-related factors associated with readmission after radical cystectomy (RC) for bladder cancer. In this era of healthcare reform, hospital performance measures, such as readmission, are beginning to affect provider reimbursement. Given its high readmission rate, RC could be a target for quality improvement. Methods: We reviewed bladder cancer patients who underwent RC in California’s State Inpatient Database (2005–2009) of the Healthcare Cost and Utilization Project. We examined patient-(e.g., race, discharge disposition) and provider-related factors (e.g., volume) and evaluated their association with 30-day readmission. Multivariable logistic regression was used to examine associations of interest. Results: Overall, 22.8% (n = 833) of the 3649 patients who underwent RC were readmitted within 30 days. Regarding disposition, 34.8%, 50.8%, and 12.2% were discharged home, home with home healthcare, and to a post-acute care facility (PACF), respectively. Within 30 days, 20.3%, 20.9%, and 42.3% were discharged home, home with home healthcare, and to a PACF were readmitted, respectively. African Americans (odds ratio [OR] 1.64, 95% confidence interval [CI] 1.07–2.50), having ≥2 comorbidities (OR 1.42, 95% CI 1.06–1.91), receiving a neobladder (OR 1.45, 95% CI 1.09–1.93), and discharged to a PACF (OR 3.79, 95% CI 2.88–4.98) were independent factors associated with readmission. Hospital stays ≥15 days were associated with less readmission (OR 0.43, 95% CI 0.27–0.67, p = 0.0002). Procedure volume was not associated with complication, in-hospital mortality, or readmission. Conclusions: About one-fifth of patients undergoing RC are readmitted. Patients who are discharged to a PACF, African American, and who have more extensive comorbidities tend to experience more readmissions. Increased efforts with care coordination among these patients may help reduce readmissions. PMID:26279713

    Purpose Traditionally, the surgical repair of umbilical hernia in cirrhotic patients with ascites is avoided because of a significant recurrence rate and perioperative morbidity/mortality. However, recent reports recommend early elective surgery in these patients because surgery-related complications can be reduced with minimally invasive surgery and development of perioperative patient care. The current study was conducted to analyze safety and feasibility of umbilical hernia repairs performed in a single institute. Methods A single center retrospective analysis of patients' data was conducted. Eighteen patients with umbilical hernia accompanied by liver cirrhosis underwent hernia repair in the period between 2005 and 2012. The charts of these patients were reviewed and demographic data, postoperative complications, and recurrence were recorded. Results Eleven males and seven females with a mean age of 62.9 years were analyzed. Two of the patients were classified as Child's class A, 11 as Child's class B, and five as Child's class C. Four patients underwent emergency surgery because of perforations in the hernia sac in two cases and incarcerated hernias in the other two cases. Of the 18 patients who underwent surgery, four (22%) experienced a recurrence, three (17%) developed edema at the surgical sites, one (5%) experienced hepatic coma, and one (5%) showed postoperative variceal hemorrhage. All of these events occurred after emergency surgery. Conclusion In contrast to traditional concepts, early and elective repair of umbilical hernia can be performed easily and safely in cirrhotic patients. PMID:26236698

    Objective Tracheal intubation with one-lung ventilation is considered mandatory for thoracoscopic surgery. This study reported the experience of thoracoscopic lung resection without endotracheal intubation in a single institution. Methods From August 2009 through July 2012, 285 consecutive patients were treated by nonintubated thoracoscopic surgery using epidural anesthesia, intrathoracic vagal blockade, and sedation for lobectomy, segmentectomy, or wedge resection in a tertiary medical center. The feasibility and safety of this technique were evaluated. Results The final diagnosis for surgery were primary lung cancer in 159 patients (55.8%), metastatic lung cancer in 17 (6.0%), benign lung tumor in 104 (36.5%), and pneumothorax in 5 (1.8%). The operative methods consisted of conventional (83.2%) and needlescopic (16.8%) thoracoscopic surgery. The operative procedures included lobectomy in 137 patients (48.1%), wedge resection in 132 (46.3%), and segmentectomy in 16 (5.6%). Collapse of the operative lung and inhibition of coughing were satisfactory in most of the patients. Fourteen (4.9%) patients required conversion to tracheal intubation because of significant mediastinal movement [5], persistent hypoxemia [2], dense pleural adhesions [2], ineffective epidural anesthesia [2], bleeding [2], and tachypnea [1]. One patient (0.4%) was converted to thoracotomy because of bleeding. No mortality was noted in our patients. Conclusions Nonintubated thoracoscopic lung resection is technically feasible and safe in selected patients. It can be a valid alternative in managing patients with pulmonary lesions. PMID:22934136

    From 1990 to 1997, 16 consecutive patients with stage III and IVa invasive thymoma were treated in a single institution with primary chemotherapy consisting in adriamycin (40 mg m(-2)), cisplatin (50 mg m(-2)) administered intravenously on day 1, vincristine (0.6 mg m(-2)) on day 2 and cyclophosphamide (700 mg m(-2)) on day 4 (ADOC). The courses were repeated every 3 weeks. The aim was to evaluate the impact of this cytotoxic regimen with respect to response rate, per cent of patients radically resected, time to progression and overall survival. Two complete responses (one clinical and one pathological) and 11 partial responses were observed (overall response rate 81.2%); two patients had stable disease and one progressed. Toxicity was mild as only two patients developed grade III/IV neutropenia and one patient grade III nausea/vomiting. Nine patients were radically resected (five out of ten with stage III, and four out of six with stage IVa). Median time to progression and overall survival was 33.2 and 47.5 months respectively. Three patients were alive and disease free after more than 5 years. The ADOC scheme is highly active and manageable in the treatment of locally advanced thymoma. As a preoperative approach it should be offered to patients not amenable to surgery or to those surgically resectable but with a great deal of morbidity. PMID:10555755

    In a single institution, in a group of 28 myeloma patients deemed eligible for autologous transplant, stem cell mobilization was attempted using filgrastim: 26 individuals were given 31 autografts employing 1–4 (median three) apheresis sessions, to obtain a target stem cell dose of 1 x 106 CD34 +ve viable cells / Kg of the recipient. The median number of grafted CD34 cells was 7.56 x 106 / Kg of the recipient; the range being 0.92 to 14.8. By defining as poor mobilizers individuals in which a cell collection of < 1 x 106 CD34 viable cells / Kg was obtained, a subset of eight poor mobilizers was identified; in two patients the autograft was aborted because of an extremely poor CD34 +ve cell yield (< 0.2 x 106 CD34 +ve viable cells / Kg of the recipient) after four apheresis sessions. The long-term overall survival of the patients grafted with > 1 x 106 CD34 +ve viable cells / Kg was better (80% at 80 months) than those grafted with < 1 x 106 CD34 +ve viable cells / Kg (67% at 76 months). Methods to improve stem cell mobilization are needed and may result in obtaining better results when autografting multiple myeloma patients. PMID:21415967

    Purpose: To report the long-term follow-up of a cohort of adult patients with supratentorial low-grade glioma treated at a single institution. Methods and Materials: A cohort of 145 adult patients treated at the London Regional Cancer Program between 1979 and 1995 was reviewed. Results: With a median follow-up of 105 months, the median progression-free survival was 61 months (95% confidence interval, 53-77), and the median overall survival was 118 months (95% confidence interval, 93-129). The 10- and 20-year progression-free and overall survival rate was 18% and 0% and 48% and 22%, respectively. Cox regression analysis confirmed the importance of age, histologic type, presence of seizures, Karnofsky performance status, and initial extent of surgery as prognostic variables for overall and cause-specific survival. Function among long-term survivors without tumor progression was good to excellent for most patients. Conclusion: Low-grade glioma is a chronic disease, with most patients dying of their disease. However, long-term survival with good function is possible. Survival is determined primarily by the disease factors with selection and timing of adjuvant treatments having less influence on outcome.

    Purpose. In this retrospective case review we analyze the outcomes of patients treated for intradiverticular bladder tumors (IDT). Materials and Methods. A retrospective case review was done between January 2002 and May 2014 in Hotel-Dieu de France hospital. The series included 17 patients diagnosed with IDT, all males with a mean age of 49.8 years. Results. One patient was treated with tumor resection and adjuvant BCG instillation with no recurrence on follow-up cystoscopies and urine cytologies. 64% of patients were treated by diverticulectomy. Mean follow-up time was 38.7 months. At the end of the follow-up, 81% were disease-free. One patient had a radical cystectomy 6 months after diverticulectomy for recurrent high grade tumor; another one had a nodal metastasis 10 months after diverticulectomy and was managed with chemotherapy. 29% of patients were treated with radical cystectomy. Mean follow-up time was 28.4 months. No recurrence was documented on annual CT scans. Conclusions. Our data support a conservative approach for tumors confined to the bladder diverticulum, even in high grade or in the presence of CIS provided complete removal is feasible and close follow-up is ensured.

    Background Therapy-related myeloid neoplasms (t-MN) occur as late complications of cytotoxic therapy. This study reviewed clinical and cytogenetic characteristics of patients with t-MN at a single institution in Korea. Methods The study subjects included 39 consecutive patients diagnosed with t-MN. Each subject's clinical history of previous diseases, treatments, and laboratory data was reviewed, including cytogenetics. The primary diagnosis was hematologic malignancy in 14 patients and solid tumor in 25 patients. Results Therapy-related acute myeloid leukemia (t-AML, 66.7%) was found to be more common than therapy-related myelodysplastic syndrome (t-MDS). Primary hematologic malignancies that were commonly implicated included mature B-cell neoplasm and acute leukemia. Breast cancer was the most common primary solid tumor. The mean time interval from cytotoxic therapy initiation to t-MN detection was 49 months. Chromosomal aberrations were observed in 35 patients, and loss of chromosome 5, 7, or both accounted for 41% of all cases. Balanced rearrangements occurred in 13 patients; these patients showed shorter latency intervals (mean, 38 months) than patients with loss of chromosome 5 or 7 (mean, 61 months). Conclusions In this study, we determined the clinical and cytogenetic characteristics of Korean patients with t-MN. Although our results were generally consistent with those of previous reports, we found that t-MN resulting from de novo leukemia was common and that t-AML was more common than t-MDS at presentation. Multi-institutional studies involving a larger number of patients and additional parameters are required to investigate the epidemiology, genetic predisposition, and survival rate of t-MN in Korea.

    Purpose To analyze treatment outcome and side effects of adjuvant radiotherapy using radiotherapy fields and doses which have evolved over the last two decades in a single institution. Materials and Methods Forty-one patients received radiotherapy after orchiectomy from 1996 to 2007. At our institution, the treatment field for stage I seminoma has changed from dog-leg (DL) field prior to 2003 to paraaortic (PA) field after 2003. Fifteen patients were treated with the classic fractionation scheme of 25.5 Gy at 1.5 Gy per fraction. Other patients had been treated with modified schedules of 25.05 Gy at 1.67 Gy per fraction (n=15) and 25.2 Gy at 1.8 Gy per fraction (n=11). Results With a median follow-up of 112 months, the 5-year and 10-year survival rates were 100% and 96%, respectively, and 5-year and 10-year relapse-free survival rates were both 97.1%. No in-field recurrence occurred. Contralateral seminoma occurred in one patient 5 years after treatment. No grade III-IV acute toxicity occurred. An increased rate of grade 1-2 acute hematologic toxicity was found in patients with longer overall treatment times due to 1.5 Gy per fraction. The rate of grade 2 acute gastrointestinal toxicity was significantly higher with DL field than with PA field and also higher in the 1.8-Gy group than in the 1.5-Gy and 1.67-Gy groups. Conclusion Patients with stage I seminoma were safely treated with PA-only radiotherapy with no pelvic failure. Optimal fractionation schedule needs to be explored further in order to minimize treatment-related toxicity. PMID:25510743

    Summary Objectives While surgery with or without adjuvant radiation therapy (RT) is the standard of care for oral cavity cancer (OCC), a select group requires nonsurgical treatment. We provide a single-institution experience using definitive chemotherapy and RT for primary OCC. Materials and methods We examined 73 patients with previously untreated, non-metastatic primary OCC treated definitively from 1990 to 2011. There were 39 male and 34 female, with a median age of 63 years (range, 35–89). The disease distribution was Stage I and II (7% each), Stage III (14%), and Stage IV (73%). Oral tongue was the most common (48%), followed by floor of mouth (19%), retromolar trigone (13.7%), and others (8.2%). Median tumor dose was 70 Gy. Sixty-two percent of patients (n = 45) were treated with concurrent chemotherapy, predominantly platinum-based. Results Median follow-up among surviving patients was 73.1 months (interquartile range 14.2– 81.4 months). Actuarial 5-year overall survival was 15%. Incidences of locoregional and distant failures were 41.1% and 20.5%, respectively. Kaplan-Meier estimated 5-year rates of locoregional control and freedom from distant metastasis were 37% and 70%, respectively. Mucositis was the most common ≥ Grade 3 acute toxicity (49%). Incidences of Grade 3 late dysphagia and trismus were 15% and 13%, respectively. Conclusion This study demonstrates over 20 years of experience using definitive chemoradiation for OCC at our institution. Our results illustrate the challenges in treating patients with advanced disease who are not surgical candidates, and the need for adequate and early treatment to prevent distant disease and improve survival outcomes.

    Purpose: To report on 32 patients who survived {>=}5 years from brain metastases treated at a single institution. Methods and Materials: The records of 1288 patients diagnosed with brain metastases between 1973 and 1999 were reviewed. Patients were treated with whole-brain radiation therapy (WBRT), surgery, and/or stereotactic radiosurgery (SRS). Thirty-two (2.5%) {>=}5-year survivors were identified. Factors contributing to long-term survival were identified. Results: Median survival was 9.3 years for {>=}5-year survivors. Seven of these patients lived {>=}10 years. Female gender was the only patient characteristic that correlated with better survival (p = 0.0369). When these patients were compared with <5-year survivors, age <65 years (p = 0.0044), control of the primary at diagnosis (p = 0.0052), no systemic disease (p = 0.0012), recursive partitioning analysis (RPA) Class 1 (p = 0.0002 with Class 2; p = 0.0022 with Class 3), and single brain metastasis (p = 0.0018) were associated with long-term survival in the univariate logistic regression model. In the multivariate model, RPA Class 1 compared with Class 2 (OR = 0.39, p = 0.0196), surgery (OR = 0.16, p < 0.0001), and SRS (OR = 0.41, p = 0.0188) were associated with long-term survival. Conclusions: For patients with good prognostic factors such as young age, good RPA characteristics and single metastasis, treatment with surgery or SRS offers the best chance for long-term survival.

    Our hospital, a Tennessee Surgical Quality Collaborative (TSQC) member, adopted a statewide colorectal care bundle intended to reduce surgical site infections (SSI) in elective colorectal cases. The bundle includes proper antibiotics/dosing, normoglycemia, normothermia, supplemental oxygen six hours postoperatively, and early enteral nutrition. A single-institution retrospective study of our National Surgical Quality Improvement Program (NSQIP) database for the rates of SSI before and after the colorectal bundle. We compared our SSI rates to TSQC hospitals as well as NSQIP datasets. Because of low case numbers in the NSQIP data, National Healthcare Safety Network (NHSN) data collected at our institution was used to compare our colorectal SSI before and after our colorectal bundle. From January 2010 to December 2011, 188 patients underwent nonemergent colorectal surgery in the NSQIP data. Of these, 5.4 per cent (10/188) developed superficial SSIs. During this same time, the rate of the TSQC superficial SSI was 7.1 per cent and NSQIP was 7.8 per cent. From January 2013 to October 2014, after the colorectal bundle started, 76 patients in NSQIP underwent nonemergent colorectal surgery. Of these, 6.5 per cent (5/76) developed superficial SSI, compared with 5.5 per cent in TSQC and 5.5 per cent in NSQIP. NHSN data showed a prebundle rate of 11 per cent and a postbundle rate of 3.5 per cent (P < 00.1, χ(2)). After adopting a colorectal bundle aimed at reducing SSIs, we did not improve our SSI rates in NSQIP; however, our NHSN data demonstrated considerable improvement. Differences in data collection may affect SSI rates, and ultimately "quality" based reimbursement. Implementation of the bundle did improve outcomes in colorectal surgery. PMID:27097625

    Transfusion related acute Lung injury (TRALI) though a serious blood transfusion reaction with a fatality rate of 5-25 % presents with acute respiratory distress with hypoxaemia and noncardiac pulmonary oedema within 6 h of transfusion. In non fatal cases, it may resolve within 72 h or earlier. Although reported with an incidence of 1:5000, its true occurrence is rather unknown. Pathogenesis is believed to be related to sequestration and adhesion of neutrophils to the pulmonary capillary endothelium and its activation leading to its destruction and leaks. The patient's underlying condition, anti-neutrophil antibody in the transfused donor plasma and certain lipids that accumulate in routinely stores blood and components are important in its aetiopathogenesis. Patient's predisposing conditions include haematological malignancy, major surgery (especially cardiac), trauma and infections. The more commonly incriminated products include fresh frozen plasma (FFP), platelets (whole blood derived and apheresis), whole blood and Packed RBC. Occasional cases involving cryoprecipitate and Intravenous immunoglobulin (IVig) have also been reported. We present a 15 year single institution experience of TRALI, during which we observed 9 cases among 170,871 transfusions, giving an incidence of 1:19,000. We did not encounter cases of haematological malignancy or cardiac surgery in our TRALI patients. Among the blood products, that could be related to TRALI in our patients included solitary cases receiving cryoprecipitate, IVIg, and recombinant Factor VII apart from platelets and FFP. All patients were treated with oxygen support. Six patients required mechanical ventilation. Off label hydrocortisone was given to all patients. There were no cases of fatality among our patients.

    Purpose: In the absence of randomized study data, institutional case series have shown brachytherapy (BT) to produce excellent biochemical control (bNED) in patients with localized prostate cancer compared with alternative curative treatments. This study was designed to overcome some of the limitations of case series studies by using a matched-pair design in patients treated contemporaneously with BT and external beam radiation therapy (EBRT) at a single institution. Methods and Materials: Six hundred one eligible patients treated between 1998 and 2001 were prospectively followed up in our institutional databases and matched on a 1:1 basis for the following known prognostic variables: prostate-specific antigen (PSA) level, Gleason score, T stage, the use and duration of neoadjuvant androgen deprivation therapy, and the percentage of positive tissue core samples. Two hundred seventy-eight perfect matches of patients (139 in each group) with low- and intermediate-risk cancer were further analyzed. bNED (Phoenix definition) was the primary endpoint. Other endpoints were toxicity, PSA kinetics, and the secondary use of androgen deprivation therapy. Results: The 5-year bNED rates were 95% (BT) and 85% (EBRT) (p < 0.001). After 7 years, the BT bNED result was unchanged, but the rate in EBRT patients had fallen to 75%. The median posttreatment PSA nadirs were 0.04 ng/mL (BT) and 0.62 ng/mL (EBRT, p < 0.001), which predicted a higher ongoing treatment failure rate in association with EBRT use than with BT use. Late urinary toxicity and rectal/bowel toxicity were worse in patients treated with BT and EBRT, respectively. Conclusions: BT for both low-risk and selected intermediate-risk cancers achieves exceptional cure rates. Even with dose escalation, it will be difficult for EBRT to match the proven track record of BT seen over the past decade.

    In radical cystectomy, under-nutrition is common and has detrimental physiological and clinical effects, which can lead to increased complications and prolonged recovery. This article compares measurements and outcomes across continents in this patient population with advanced bladder cancer. The association of preoperative nutritional risk, nutritional status, and length of stay is equal across continents, and the results promote increased clinical awareness that women at severe risk should be identified preoperatively.

    Introduction We sought to evaluate the cost effectiveness of perioperative use of alvimopan in cystectomy and urinary diversion. A recent randomized controlled trial demonstrated the efficacy of alvimopan in reducing postoperative ileus and length of stay in cystectomy; however, a major limitation was the exclusion of epidural analgesia. Materials and methods Eighty–six cystectomy and urinary diversion procedures performed by seven surgeons were analyzed between January 2008 and April 2012. The first 50 patients did not receive alvimopan perioperatively, while the subsequent 36 received a single dose of 12 mg preoperatively and then 12 mg every 12 hours for 15 doses or until discharge. Results The groups were equal with respect to age, gender, indication, surgeon, and type of diversion. Patients who received alvimopan experienced a shorter length of stay (LOS) versus those in who did not receive alvimopan (10.5 vs. 8.6 days, p = 0.005, 95% CI 0.6–3.3). Readmission for ileus was low in both alvimopan and control groups (0% and 4.4%, respectively). Costs were significantly lower in the alvimopan group than the control groups (2012 USD 32,443 vs. 40,604 p <0.001). This difference stood up to multivariate analysis with a $7,062 difference in hospital stay. Conclusions Use of alvimopan in the routine perioperative care of our cystectomy and urinary diversion patients has decreased LOS by 1.9 days. Additionally, institution of routine perioperative alvimopan has reduced costs by $7,062 per admission (20% reduction). This demonstrates a real world application of alvimopan at a moderate volume center. PMID:25667750

    Background: Radical cystectomy may provide optimal survival outcomes in the management of clinical T1 bladder cancer. We present our data from a large, multi-institutional, contemporary Canadian series of patients who underwent radical cystectomy for clinical T1 bladder cancer in a single-payer health care system. Methods: We collected a pooled database of 2287 patients who underwent radical cystectomy between 1993 and 2008 in 8 different centres across Canada; 306 of these patients had clinical T1 bladder cancer. Survival data were analyzed using Kaplan-Meier method and Cox regression analysis. Results: The median age of patients was 67 years with a mean follow-up time of 35 months. The 5-year overall, disease-specific and disease-free survival was 71%, 77% and 59%, respectively. The 10-year overall and disease-specific survival were 60% and 67%, respectively. Pathologic stage distribution was p0: 32 (11%), pT1: 78 (26%), pT2: 55 (19%), pT3: 60 (20%), pT4: 27 (9%), pTa: 16 (5%), pTis: 28 (10%), pN0: 215 (74%) and pN1-3: 78 (26%). Only 12% of patients were given adjuvant chemotherapy. On multivariate analysis, only margin status and pN stage were independently associated with overall, disease-specific and disease-free survival. Interpretation: These results indicate that clinical T1 bladder cancer may be significantly understaged. Identifying factors associated with understaged and/or disease destined to progress (despite any prior intravesical or repeat transurethral therapies prior to radical cystectomy) will be critical to improve survival outcomes without over-treating clinical T1 disease that can be successfully managed with bladder preservation strategies.

    Objectives During surgery the volume of administered fluid is debated. Pro-atrial natriuretic peptide (proANP) is released by atrial distension, and we evaluated the relationship between changes in proANP associated with perioperative fluid balance. Design Prospective observational study. Setting One university/tertiary centre. Participants The study included patients who underwent radical cystectomy. Plasma for determination of proANP was obtained before surgery, after resection of the bladder, and at the end of surgery for 20 robotic-assisted radical cystectomy (RARC) and 20 open radical cystectomy (ORC) procedures. Results The blood loss was 1871 (95% CI 1267 to 2475) vs 589 mL (378 to 801) in the ORC and RARC groups (p=0.001), respectively, and fluid balance was positive by 1518 mL (1215 to 1821) during ORC, and by 1858 mL (1461 to 2255) during RARC (p=0.163). Yet, at the end of ORC, plasma proANP was reduced by 23% (14% to 32%, p=0.001), while plasma proANP did not change significantly during RARC. Thus, plasma proANP was associated both with the perioperative blood loss (r= −0.475 (0.632 to −0.101), p=0.002), and with fluid balance (r=0.561 (0.302 to 0.740), p=0.001), indicating that a stable plasma proANP required a fluid surplus by 2.4 L (2.0 to 2.7). Conclusions There was a correlation between intraoperative haemorrhage and a decrease in plasma proANP and, taking plasma proANP to indicate filling of the heart, about 2.5 L surplus volume of lactated Ringer's solution appears to maintain cardiac preload during cystectomy.

    Surgical treatment of invasive carcinoma of the bladder in males includes total cystectomy removal of the prostate, seminal vesicles, and the distal parts of the urethers and the pelvic lymph node dissection as well. At this moment it is not possible to recommend a particular type of urinary diversion, but today in clinical practice commonly used derivative are ileal orthotopic neobladder as the continent one and ileal conduit as non-continent urinary diversion. Continent urinary diversion after radical cystectomy are the result of the application of technological innovation in surgery, but also knowledge, imagination and skill of well trained urologist. This type of operation significantly improves the quality of life in patients who underwent radical cystectomy, and the proposal is to operate whenever there is a possibility for this type of procedure. Also it is very important, during surgery to respect oncological principles, of complete removal of tumorous tissue and that the functional principle of ensur- ing that the patients have daytime and also nighttime continence later on after the surgery.

    ABSTRACT Introduction and Objective Radical cystectomy (RC) with pelvic lymph node dissection is the standard treatment for muscle invasive bladder cancer and the oncologic outcomes following it are directly related to disease pathology and surgical technique. Therefore, we sought to analyze these features in a cohort from a Brazilian tertiary oncologic center and try to identify those who could negatively impact on the disease control. Patients and Methods We identified 128 patients submitted to radical cystectomy, for bladder cancer treatment, from January 2009 to July 2012 in one oncology tertiary referral public center (Mario Penna Institute, Belo Horizonte, Brazil). We retrospectively analyzed the findings obtained from their pathologic report and assessed the complications within 30 days of surgery. Results We showed similar pathologic and surgical findings compared to other large series from the literature, however our patients presented with a slightly higher rate of pT4 disease. Positive surgical margins were found in 2/128 patients (1.5%). The medium number of lymph nodes dissected were 15. Major complications (Clavien 3 to 5) within 30 days of cystectomy occurred in 33/128 (25.7%) patients. Conclusions In the management of invasive bladder cancer, efforts should focus on proper disease diagnosis and staging, and, thereafter, correct treatment based on pathologic findings. Furthermore, extended LND should be performed in all patients with RC indication. A critical analysis of our complications in a future study will help us to identify and modify some of the factors associated with surgical morbidity. PMID:27286104

    Introduction: We aimed to enumerate the rate of pelvic recurrence following radical cystectomy at university-affiliated hospitals in Canada. Methods: Canadian, university-affiliated hospitals were invited to participate. They were asked to identify the first 10 consecutive patients undergoing radical cystectomy starting January 1, 2005, who had urothelial carcinoma stages pT3/T4 N0-2 M0. The first 10 consecutive cases starting January 1, 2005 who met these criteria were the patients submitted by that institution with information regarding tumour stage, age, number of nodes removed, and last known clinical status in regard to recurrence and patterns of failure. Results: Of the 111 patients, 80% had pT3 and 20% pT4 disease, with 62% being node-negative, 14% pN1, and 27% pN2; 57% had 10 or more nodes removed. Cumulative incidence of pelvic relapse was 40% among the entire group Conclusions: This review demonstrates a high rate of pelvic tumour recurrence following radical cystectomy for pT3/T4 urothelial cancer.

    Robot-assisted radical cystectomy (RARC) is an evolving technique for the treatment of muscle-invasive bladder cancer (MIBC); however, its effectiveness compared with open radical cystectomy (ORC) - the established modality - is debated. Six specific areas of evidence are critically important for supporting the continuing use of RARC for MIBC, including technical aspects of surgery, perioperative outcomes, complications, oncological outcomes, functional outcomes, and financial costs. Considerable progress has been made regarding these aspects and data show that RARC replicates the technical benchmarks of ORC in terms of success of cystectomy, lymph node dissection, and urinary diversion, and could offer advantages over the more-established technique. Despite some clear benefits of RARC (such as reduced blood loss) other perioperative outcomes, including duration of inpatient stay and 30-90 day complication rates, seem to be similar to those of ORC. Current data on oncological and functional outcomes are promising, but robust data from prospective studies will help determine the indications for use of RARC for treating MIBC in the future.

    Background: Acute kidney injury (AKI) is a common complication after surgery and increases costs, morbidity, and mortality of hospitalized patients. While radical cystectomy associates significantly with an increased risk of serious complications, including AKI, risk factors of AKI after radical cystectomy has not been reported. This study was performed to determine the incidence and independent predictors of AKI after radical cystectomy. Methods: All consecutive patients who underwent radical cystectomy in 2001-2013 in a single tertiary-care center were identified. Their demographics, laboratory values, and intraoperative data were recorded. Postoperative AKI was defined and staged according to the Acute Kidney Injury Network criteria on the basis of postoperative changes in creatinine levels. Independent predictors of AKI were identified by univariate and multivariate logistic regression analyses. Results: Of the 238 patients who met the eligibility criteria, 91 (38.2%) developed AKI. Univariate logistic regression analyses showed that male gender, high serum uric acid level, and long operation time associated with the development of AKI. On multivariate logistic regression analysis, preoperative serum uric acid concentration (odds ratio [OR] = 1.251; 95% confidence interval [CI] = 1.048-1.493; P = 0.013) and operation time (OR = 1.005; 95% CI = 1.002-1.008; P = 0.003) remained as independent predictors of AKI after radical cystectomy. Conclusions: AKI after radical cystectomy was a relatively common complication. Its independent risk factors were high preoperative serum uric acid concentration and long operation time. These observations can help to prevent AKI after radical cystectomy. PMID:26283877

    Primary cerebellar glioblastoma (CGB) comprises only 0.4-3.4% of all intracranial glioblastoma. The impact of surgical resection on survival and the efficacy of adjuvant therapies are uncertain as CGB is underrepresented in most studies. To elucidate prognostic factors we performed a single-institutional review of the largest series to date of CGB. The University of Texas MD Anderson Cancer Center database was reviewed from 1990 to 2010. Twenty-one consecutive patients met criteria for inclusion. The Kaplan-Meier product limit method was used to estimate overall survival (OS) and progression-free survival (PFS); groups were compared using the log-rank statistic. The multivariate Cox proportional hazards models were fitted to examine the association of resection with OS and PFS adjusted for other clinical variables. The median age was 39.9 years, and Karnofsky performance status (KPS) was ≥ 80 in 61.5% of patients. The mean extent of resection for contrast enhancement (EOR-CE) was 93.8% (SD = 10.4%; median = 100%), and the median follow-up was 18.4 months (range 1.5-116.1 months). There was no significant association of EOR with OS or PFS. On univariate analysis the presence of leptomeningeal disease (LMD) was associated with a worse OS (6.1 vs. 24.1 months; P = 0.0001) and PFS (3.3 vs. 9 months; P = 0.019). Patients who had adjuvant chemotherapy (CT) had extended PFS (10.1 vs. 2.8 months; P < 0.0001). Adjustment for the presence of leptomeningeal disease (LMD) tended toward an increased risk of progression (HR = 3.46; 95% confidence interval [CI], 0.83-14.5; P = 0.09) and was associated with a significantly increased risk of death (HR = 15.2; 95% CI, 1.3-180; P = 0.03). Having received adjuvant chemotherapy was associated with a decreased risk of progression (HR = 0.02; 95% CI, 0-0.26; P = 0.003). The presence of LMD is a critical factor in the clinical behavior of CGB resulting in markedly decreased OS and PFS. Adjuvant CT resulted in increased PFS but did not

    Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiologic entity. Its management and outcome in the oncology population is limited because it is still difficult to identify despite an increasingly recognized occurrence. This is the largest retrospective study of PRES in cancer patients reported from a single institution. We explore the clinical manifestations and radiologic features to comprehensively assess PRES in order to prevent permanent neurologic deficits and mortality. We retrospectively identified 69 patients with cancer who developed PRES at MDACC between 01/2006 to 06/2012. Clinical and radiographic data were abstracted from their records and reviewed for our analysis. Mean age at PRES onset was 52 ± 17.8 years. Fifty-two (75 %; p < 0.001) patients were women. Most common diagnoses were leukemia (30 %) and lymphoma (12 %). Forty-eight (70 %) patients were treated with chemotherapy, 21 (30 %) bone marrow transplant and 14 (20 %) tacrolimus. Most common clinical presentation was seizures (67 %). PRES was associated with hypertension in 62 (90 %) patients. On brain MRI, 33 (44 %) patients had some evidence of hemorrhage, 22 (73 %) of these were thrombocytopenic. Thirty-five (51 %) patients fully recovered and 19 (28 %) had permanent neurological deficits. Morbidity and mortality were associated with continuation with offending agent, thrombocytopenia, variations in mean arterial pressure ≥20 mmHg, electrographic seizures at onset, atypical MRI pattern and delay in diagnostic imaging (7.4 ± 4.8 days vs. 1.9 ± 1.8 days; p = 0.031) as half of them did not receive a prompt intervention. Special attention should be given to patients who present with high-risk factors in order to prevent development of PRES or decrease patient morbidity and mortality. Management of PRES should be guided by the radiographic findings. Overall, early recognition, discontinuation of the offending agents, correction of thrombocytopenia

    The aim of this study is to access the feasibility, toxicity profile, and tumour outcome of an organ preservation curative approach in non-metastatic muscle-invasive bladder cancer. A retrospective analysis was conducted on patients affected by M0 bladder cancer, who refused cystectomy and were treated with a curative approach. The standard bladder preservation scheme included maximal transurethral resection of bladder tumour (TURBT) and combination of radiotherapy and platin-based chemotherapy, followed by endoscopic evaluation, urine cytology, and instrumental evaluation. Thirteen patients fulfilled the inclusion criteria. TNM stage was cT2cN0M0 and cT2cNxM0, in 12 and one patients, respectively. All patients had transitional cell cancer. Twelve patients completed the whole therapeutic programme (a bimodal treatment without chemotherapy for one patient). Median follow-up is 36 months. None of the patients developed severe urinary or intestinal acute toxicity. In 10 patients with a follow-up > 6 months, no cases of severe late toxicity were observed. Response evaluated in 12 patients included complete response and stable disease in 11 patients (92%), and one patient (8%), respectively. At the time of data analysis (March 2016), 10 patients (77%) are alive with no evidence of disease, two patients (15%) died for other reasons, and one patient has suspicious persistent local disease. The trimodality approach, including maximal TURBT, radiotherapy, and chemotherapy for muscle-invasive bladder cancer, is well-tolerated and might be considered a valid and feasible option in fit patients who refuse radical cystectomy.

    Introduction: Radical cystectomy is the standard treatment for muscle invasive bladder cancer. We assessed clinical outcomes in patients found to have no evidence of disease (i.e., pT0N0) following radical cystectomy. Methods: We collected and pooled a database of 2287 patients who underwent radical cystectomy between 1993 and 2008 in eight centres across Canada. Of this number, 135 patients were found to have pT0N0 bladder cancer at the time of cystectomy. Survival data and prognostic variables were analyzed using Kaplan-Meier method and Cox proportional hazard regression analysis. Results: Median patient age was 66 years with a mean follow-up of 42 months. Clinical stage distribution was Tis 8.9%, Ta 1.5%, T1 20.7%, T2 45.2%, T3 5.2%, and T4 5.2%. The five-year recurrence-free survival (RFS), disease-specific survival (DSS) and overall survival (OS) were 83%, 96%, and 88%, respectively. The 10-year RFS, DSS and OS were 66%, 92%, and 70%, respectively. On Cox proportional regression analysis, no variables were associated with disease recurrence and only patient age was associated with overall survival. Interpretation: Patients with pT0N0 pathology after cystectomy have excellent outcomes with high five- and 10-year RFS, DSS and OS. However, there is still a risk of tumour recurrence in this patient population and thus postoperative surveillance is still required. PMID:22709882

    Background: Data from the general surgery literature suggests that patient morphometric data obtained from preoperative imaging may help predict a patient’s risk around surgery. Objectives: In this context, we evaluated for associations between psoas muscle area and short-term convalescence following radical cystectomy. Methods: After identifying patients who underwent radical cystectomy at our institution (2008 to 2013), we calculated their psoas muscle area from staging computed tomography scans using established analytic morphomic techniques. We then determined early recovery among patients with high and low psoas muscle area using the validated Convalescence and Recovery Evaluation (CARE) questionnaire—a 27-item survey, divided into four domains (activity, cognitive, gastrointestinal, and pain recovery). Finally, we assessed the relationship between psoas muscle area and changes in CARE scores with nested linear regression models. Results: Among the 86 men and among 31 women in our cohort, the median total psoas muscle area was 2,544 mm2 and 1,511 mm2, respectively (P <  0.001 for the comparison). While there was no association between psoas muscle area and recovery in men, women with higher (versus lower) total psoas muscle area had smaller decreases in their pain scores postoperatively and a quicker return to their baseline level (P = 0.05). Activity scores also approached baseline levels faster among women with higher psoas muscle area, although this finding did not reach statistical significance. Conclusions: Psoas muscle area is potentially an important preoperative predictor of recovery for women undergoingradical cystectomy. More broadly speaking, analytic morphomics may represent a novel approach to better understand perioperative risk. PMID:27376142

    Introduction Radical cystectomy in elderly patients is a controversial issue that has noticed an increase in importance overtime because of the lengthening average life span. Our objective was to determine if there were significant differences in the perioperative outcomes of patients over 70 years with bladder cancer treated with laparoscopic radical cystectomy (LRC) compared to those of younger patients. Material and methods We selected 180 patients who underwent LRC in our department in the period between 2005-2012. We divided them into 2 groups: 57% <70 years and 43% >70 years, and we compared the different parameters such as: comorbidities, intraoperative and post-operative complications, TNM stage and overall survival. Results The group <70 years had less comorbidities when compared with the group >70 years. Heterotopic urinary diversion was the diversion of choice in the elderly patients (97.4%). Paralytic ileus and the worsening of renal function were the only complications with statistical differences between the groups. Mean hospital length of stay was not significantly different between the groups. Younger and older patients had similar pathological staging : pT1 or less: 26,2 vs. 18.2%, pT2: 19.4 vs. 16.9%, pT3 38.8 vs. 37.7% and pT4 15.6 vs. 17.2%. Kaplan-Meier curves did not show significant differences in survival. Conclusions Laparoscopic radical cystectomy in the elderly patient has similar rates of perioperative morbidity when compared with the younger patient and may be offered as a treatment option in selected elderly patients.

    Purpose The aim of this study was to assess the advantages of robotic surgery, comparing perioperative and oncological outcomes between robot-assisted radical cystectomy (RARC) and open radical cystectomy (ORC). Materials and Methods Between August 2008 and May 2014, 112 radical cystectomies (42 RARCs and 70 ORCs) were performed at a single academic institution following Institutional Review Board approval. Patient demographics, perioperative variables (e.g., complications), and oncologic outcomes including metastasis-free survival (MFS), cancer-specific survival (CSS), and overall survival (OS) were reported using the Kaplan-Meier analyses. Results The median follow-up period was 40 months (range, 0–70 months) vs. 42 months (range, 0–74 months) in RARC and ORC, respectively. Baseline characteristics of both groups were balanced. Blood loss (median, [range]; 300 mL [125–925 mL] vs. 598 mL [150–2,000 mL], p=0.001) and perioperative transfusion rates (23.8% vs. 45.7%, p=0.020) were significantly lower in the RARC group than in the ORC group. The overall complication rates were greater in the ORC group, but this was not statistically significant (65.7% vs. 64.3%, p=0.878). However, there were significantly higher major complication rates in the ORC group (45.7% vs. 26.2%, p=0.040). No significant differences were found with regards to MFS, CSS, and OS. Conclusions While histopathological findings, overall complications, and survival rates do not reveal definite differences, RARC has more advantages compared to ORC in terms of estimated blood loss, perioperative transfusion rates and fewer perioperative major complications. We propose that RARC is a safer treatment modality with equivalent oncological outcomes compared to ORC. PMID:27437535

    Technical modifications in open approach to radical cystectomy and orthotopic neobladder (ONB), that is, Pfannenstiel incision, single urethral catheter, internal splint, and extraperitonealization of the ONB were done in 36 patients. Median operative time was 300 (240–360) min. Median time to move the bowel and start of oral intake was 4 days (2–8) days. Major complications occurred in 3 (8.33%) patients. Mean postoperative pain score was 2 (1–4). These modifications in open radical cystectomy resulted in better cosmesis, less pain, and more comfort to the patients as they had to carry one urobag for 3 weeks. PMID:21116377

    Gastrointestinal (GI) complications are among the most common complications following radical cystectomy and urinary diversion. The most common is postoperative ileus, although its precise pathophysiology is not completely understood. Enhanced recovery after surgery (ERAS) protocols include evidence-based steps to optimize postoperative recovery and shorten hospital stay, mainly through expedited GI function recovery. They include avoiding bowel preparation and postoperative nasogastric tube, early feeding, non-narcotic pain management, and the use of cholinergic and mu-receptor opioid antagonists. We reviewed the literature in regard to GI complications using enhanced recovery protocols and share our institutional experience with over 300 patients. PMID:27125653

    Robot-assisted surgery has become a widely used surgical approach in the management of urologic malignancies. With its initial experience in the treatment of prostate cancer, the technology rapidly expanded to other urologic malignancies including bladder cancer. Since its introduction in 2003, robot-assisted radical cystectomy has seen refinement and increased penetration over the last decade. Furthermore, urologic surgeons have expanded its use to perform urinary diversions. The concept of intracorporeal urinary diversion is still in development but continues to see increased refinement among high volume academic centers. PMID:27021910

    Radical cystectomy with extended pelvic lymphadenectomy remains the treatment of choice for muscle invasive bladder cancer and non-metastatic chorion-invasive high grade tumors resistant to treatment with intravesical chemotherapy. During the last decade the procedure has been refined and we have acquired the skills necessary to perform it using the laparoscopic approach. In this way, the oncologic and functional outcomes obtained can be compared to those of its open counterpart. This article describes in detail the technique of radical cystoprostatectomy and urinary diversion in the male patient conducted by our group in an attempt to improve the knowledge and spread of this always difficult procedure.

    Results of our recent cystectomy series revealed good survival for patients with superficial bladder tumors. The morbidity rate was low, 8.6 per cent. Our series showed a statistically significant postoperative morbidity rate in a high risk patient group, then justifying preoperative selection of patients as condidates for this major operation. However, we believe that despite relatively good results in reducing the morbitidy and mortality rates and improvement in survival, the over-all results in treatment of bladder tumors with operation alone are still unsatisfactory and there is an urgent need to develop and to investigate new and combined modalities of treatment.

    Purpose Psychological distress has been associated with an impaired immune response and poor wound healing. We hypothesized that preoperative patient reported mental health would be associated with high grade 30-day complications after radical cystectomy. Materials and Methods We retrospectively identified patients who underwent radical cystectomy for bladder cancer who completed Short Form 12 (SF-12) surveys for self-assessment of health status less than 6 months before surgery. Median physical and mental composite scores were calculated. An expert model including known predictors of postoperative high grade complications was developed, and SF-12 physical composite score and mental composite score were added to determine their association with this end point. Results From January 2010 to August 2014, 472 patients underwent radical cystectomy for bladder cancer, of whom 274 (58.1%) completed preoperative SF-12 questionnaires. Responders were more likely to be white (p=0.024), have higher preoperative albumin (p=0.037), receive neoadjuvant chemotherapy (p=0.002), have pT3/T4 disease (p=0.044) and have positive soft tissue surgical margins (p=0.006). Median SF-12 physical composite score was 43.1 (IQR 33.0–51.5) and mental composite score was 48.5 (IQR 39.5–54.7) in responders. Overall 46 (16.8%) responders experienced a high grade 30-day complication. Patients with a high grade complication had a lower preoperative median SF-12 mental composite score (44.8 vs 49.8, p=0.004) but no difference in physical composite score (39.2 vs 43.8, p=0.06). SF-12 mental composite score was also a significant predictive variable when added to our expert model (p=0.01). Conclusions Preoperative patient reported mental health was independently associated with high grade complications after radical cystectomy. Therefore, patient self-assessment of health status before surgery through validated questionnaires may provide additional information useful in predicting short

    The aim of this study is to characterize EBV expression and latency pattern in pediatric Burkitt's lymphoma in a single institution in Argentina. EBV-encoded RNA or protein was analyzed in 27 patients. EBERs was expressed in 37% of patients (29% of immunocompetent and 100% of immunosuppressed patients). EBV-positive cases were observed exclusively in patients younger than 5 years old. EBV association with immunocompetent patients exhibits the sporadic pattern in region under study, while its presence in patients infected with HIV was higher than described previously. EBV latency I profile was present in most of the patients, except for two immunosuppressed patients who displayed LMP1 expression. PMID:24027016

    The ‘genomics era’ is considered to have begun with the commencement of the Human Genome Project. As translational genomic studies can only be established when human tissue samples are available for analysis, biospecimens are now proven to be an essential element for their success. During the genomics era the necessity for more extensive biobanking infrastructure has been highlighted. With the increased number of genomic studies into cancer, it is considered that the availability of biospecimens will become the rate limiting step. Despite the efforts in international biobanking, translational genomics is hampered when there low numbers of biospecimens for a particular rare diseases and is most apparent for paediatric cancer. As there is a call for biobanking practice to be responsive to the current experimental needs of the time and for more expansive systems of tissue procurement to be established we have asked the question what role does a single institution biorepository play in the current highly networked world of translational genomics. Here we describe such a case. The Tumour Bank at The Children’s Hospital at Westmead (TB-CHW) in the western suburbs of Sydney was formally established in 1998 as a key resource for translational paediatric cancer research. During the genomics era, we show that the TB-CHW has developed into a key biospecimen repository for the cancer research community, during which time it has increasingly found itself having a vital role in the establishment of translational genomics for paediatric cancer. Here we detail metrics that demonstrate how as a single institution biorepository, the TB-CHW has been a strong participant in the advancement of translational genomics throughout the genomics era. This paper describes the significant contribution of a single institutional hospital embedded tumour biobank to the genomic research community. Despite the increased stringencies placed on biobanking practice, the TB-CHW has shown that a

    Patients with bladder (urothelial) cancer undergoing urinary diversion (UD) experience physical changes that require important adjustments in their daily lives. This integrative review aims to identify factors that influence adult adaptation to life after cystectomy with the creation of a UD. A review of primary research articles published between 1990 and 2014 was conducted using the PubMed and CINAHL Plus electronic databases. Results of the studies were summarized into 5 categories: (1) individual and family factors, (2) technical aspects related to the individual's ability to care for his or her UD, (3) perioperative nursing care, (4) educational needs, and (5) symptom experience. Bladder cancer patients treated with a cystectomy with a UD have a complex set of needs during postoperative adaptation to their reconstructed urinary system. This integrative review summarizes existing knowledge of factors that affect adaptation to a UD in patients with bladder cancer and may guide future studies. Research on this is limited and more studies are needed. PMID:27607746

    Objective To critically review the currently available evidence of studies comparing robot-assisted radical cystectomy (RARC) with open radical cystectomy (ORC). Methods A comprehensive review of the literature from Pubmed, Web of Science and Scopus was performed in April 2014. All relevant studies comparing RARC with ORC were included for further screening. A pooled meta-analysis of all comparative studies was performed and publication bias was assessed by a funnel plot. Results Nineteen studies were included for the analysis, including a total of 1779 patients (787 patients in the RARC group and 992 patients in the ORC group). Although RARC was associated with longer operative time (p <0.0001), patients in this group might benefit from significantly lower overall perioperative complication rates within 30 days and 90 days (p = 0.005 and 0.0002, respectively), more lymph node yields (p = 0.009), less estimated blood loss (p <0.00001), lower need for perioperative and intraoperative transfusions (p <0.0001 and <0.0001, respectively), and shorter postoperative length of stay (p = 0.0002). There was no difference between two groups regarding positive surgical margin rates (p = 0.19). Conclusions RARC appears to be an efficient alternative to ORC with advantages of less perioperative complications, more lymph node yields, less estimated blood loss, lower need for transfusions, and shorter postoperative length of stay. Further studies should be performed to compare the long-term oncologic outcomes between RARC and ORC. PMID:25825873

    As a treatment for high-risk bladder cancer, radical cystectomy (RC) remains a highly morbid operation with complication rates of 40-60% and mortality rates as high as 9% in the first 90 days after surgery (Aziz et al., Eur Urol 66(1):156-163, 2014; Shabsigh et al., Eur Urol 55(1):164-174, 2009). Many patients suffer from a failure-to-thrive syndrome associated with anorexia, weight loss, dehydration, and immobility. In elderly patients, failure-to-thrive may result in loss of independence and a cascade of events that increases the risk of perioperative morbidity and mortality, ultimately resulting in impaired survival. Psoas muscle mass has been used to predict morbidity and mortality after major surgical procedures in vulnerable populations with substantial comorbidities. Increasingly, psoas muscle mass is also being used to predict outcomes after RC. If patients with a high risk of impaired survival are identified preoperatively, prehabilitative interventions can be integrated into their preparation for surgical treatment (Porserud et al., Clin Rehab 28(5):451-459, 2014; Friedman et al., Nutr Clin Pract: Off Publ Am Soc Parenter Enter Nutr 30(2):175-179, 2015). This chapter discusses the role of psoas muscle mass as a predictor of negative surgical outcomes after cystectomy. PMID:26403157

    Differences between clinical (cT) and pathological tumor (pT) stage occur often after radical cystectomy (RC) for muscle-invasive bladder cancer. In order to evaluate the impact of downstaging on recurrence and survival, we selected patients from a large, contemporary, population-based series of 1,409 patients with MIBC. We included all patients who underwent RC (N=643) and excluded patients who received (neo)adjuvant therapy, those with known metastasis at time of diagnosis, and those with nonurothelial cell tumors. Disease outcomes were defined as recurrence-free survival (RFS) and relative survival (RS), as a good approximation of bladder cancer-specific survival. After applying the exclusion criteria, 375 patients were eligible for analysis. Tumor downstaging was found to be common after RC; in 99 patients (26.4%), tumor downstaging to non-muscle-invasive stages at RC occurred. Hydronephrosis at baseline and positive lymph nodes at RC occurred significantly less often in these patients. In 62 patients, no tumor was left in the cystectomy specimen. pT stage was pT1 in 20 patients and pTis in 17 patients. Patients with tumor downstaging have about a 30% higher RFS and RS compared to those without. Consequently, tumor downstaging is a favorable marker for prognosis after RC. PMID:22084800

    Purpose The use of laparoscopic radical cystectomy (LRC) for muscle-invasive bladder cancer is not yet widespread because of the technical difficulties of the procedure and the lengthy operating time. In this study, we report a single surgeon's experience with LRC. Materials and Methods Thirty patients (25 men and 5 women) with bladder cancer underwent LRC and ileal conduit by a single surgeon between November 2007 and May 2011. An extracorporeal urinary diversion was performed through 5-6 cm midline incision for specimen extraction. Results The median operating time and estimated blood loss were 527.5 minutes and 275 mL, respectively. There was no conversion to open surgery. The median time to oral intake and postoperative hospital stay were 5 days and 12 days, respectively. The rates of immediate, early postoperative and late postoperative complication were 3.3%, 20% and 20%, respectively. With 16 months of median follow-up, the overall and recurrence-free survival rates were 70% and 56.7%, respectively. Conclusion LRC is feasible for the management of invasive bladder cancer and, with appropriate patient selection, can be a good alternative to open or robot-assisted radical cystectomy in the era of robot-assisted surgery.

    The purpose of the RAZOR (randomized open vs robotic cystectomy) study is to compare open radical cystectomy (ORC) vs robot-assisted RC (RARC), pelvic lymph node dissection (PLND) and urinary diversion for oncological outcomes, complications and health-related quality of life (HRQL) measures with a primary endpoint of 2-year progression-free survival (PFS). RAZOR is a multi-institutional, randomized, non-inferior, phase III trial that will enrol at least 320 patients with T1-T4, N0-N1, M0 bladder cancer with ≈160 patients in both the RARC and ORC arms at 15 participating institutions. Data will be collected prospectively at each institution for cancer outcomes, complications of surgery and HRQL measures, and then submitted to trial data management services Cancer Research and Biostatistics (CRAB) for final analyses. To date, 306 patients have been randomized and accrual to the RAZOR trial is expected to conclude in 2014. In this study, we report the RAZOR trial experimental design, objectives, data safety, and monitoring, and accrual update. The RAZOR trial is a landmark study in urological oncology, randomizing T1-T4, N0-N1, M0 patients with bladder cancer to ORC vs RARC, PLND and urinary diversion. RAZOR is a multi-institutional, non-inferiority trial evaluating cancer outcomes, surgical complications and HRQL measures of ORC vs RARC with a primary endpoint of 2-year PFS. Full data from the RAZOR trial are not expected until 2016-2017. PMID:25626182

    The genitofemoral neuropathy is one of the most common causes of groin pain after surgery. Especially, the groin pain induced by genitofemoral nerve injury during herniorrhaphy is a well-known complication. In contrast, much attention is not paid for groin pain induced by genitofemoral nerve injury after pelvic surgery, and there have been few reports in males, although it has been reported in females. We report a 59-year-old male patient who suffered from scrotal pain caused by presumed genitofemoral nerve injury during radical cystectomy and bilateral pelvic lymphadenectomy for bladder cancer. The surgical procedure was performed in a supine position under general anesthesia, without epidural anesthesia. Postoperatively, he complained of burning and lancinating pain in bilateral scrotal area. Abnormal findings were not evident using computed tomography and ultrasonography of the pelvis, including the scrotum and testicles. He had severe allodynia of the ventral scrotum and bilateral ventromedial thigh region, with absence of cremasteric reflex. We speculated that his pain might have been surgery-induced genitofemoral neuropathy, which was caused by nerve injury during lymphadenectomy near the external iliac vessels. His scrotal pain and allodynia following the cystectomy were partially and gradually relieved after administering pregabalin, further supporting the contention that his scrotal pain was a surgery-induced neuropathy.

    This study aimed to assess the short-term efficacy of sequential therapy for T2/T3a bladder cancer with intravesical single-port laparoscopic partial cystectomy or open partial cystectomy combined with cisplatin plus gemcitabine (GC) chemotherapy in a prospective randomized controlled study. Thirty patients with bladder cancer who underwent open partial cystectomy (group A) or single-port laparoscopic partial cystectomy (group B) and received standard GC chemotherapy were analyzed. Perioperative functional indicators and tumor recurrence during a 1-year postoperative follow-up were compared between the two groups. The baseline characteristics were comparable between the two groups. The mean operative time, amount of blood loss and duration of hospital stay were 90.3 min, 182.0 ml and 7.3 days, respectively, for group A, and 105.3 min, 49.3 ml and 5.8 days, respectively, for group B. No secondary postoperative bleeding, urine leakage, wound infection or other complications were observed in the two groups. Postoperative scarring was not evident in group B. The overall incidence of surgical complications, tumor recurrence rate and complications during chemotherapy in the postoperative follow-up period of 12 months were similar between the two groups. Single-port laparoscopic partial cystectomy surgery is an idea surgical method for the treatment of invasive bladder cancer, with good surgical effect, minimal invasiveness, rapid recovery and short hospital stay. The data from 1-year postoperative follow-up showed that laparoscopic surgery was superior with regard to perioperative bleeding, postoperative recovery and duration of indwelling urinary catheter use. However, regarding the tumor recurrence rate, long-term comparative details are required to determine the effect of laparoscopic surgery. PMID:26170915

    Background: Benign ovarian cysts are common among both pre- and postmenstrual women. Surgical intervention for excision of an ovarian cyst is mandated when symptomatic, or chance for malignancy is high. The damaging effect of surgical ovarian cystectomy on ovarian reserve is debated in recent studies. Objective: In the present study we investigated serum level of anti-mullerian hormone (AMH) as an indicator of ovarian reserve before and after surgical cystectomy. Materials and Methods: 60 patients with dermoid cyst, serous cystadenoma, and mucinous cystadenoma were recruited. Measurement of serum AMH was performed prior to surgery, and at one and 3 months after laparoscopic cystectomy. Serum AMH levels were compared before and after the surgery and between various types of ovarian cyst. Results: Serum AMH level declined significantly after the surgery which recovered to 65% of its baseline value three months later. Conclusion: Decreased serum AMH can be contributed to decreased ovarian reserve after laparoscopic ovarian cystectomy. This can result from thermo-coagulation used for hemostasis during the operation. PMID:26000005

    This study delineates the roles of "selective referrals" and "practice makes perfect" in the hospital procedure volume and in-hospital mortality association for radical cystectomy and radical prostatectomy. This is a retrospective analysis of the Nationwide Inpatient Sample (years 2000-2004). All hospitalizations with primary procedure codes for radical cystectomy and radical prostatectomy were selected. The association between hospital procedure volume and in-hospital mortality was examined using generalized estimating equations and by instrumental variables approaches. There was an inverse association between hospital procedure volume and in-hospital mortality for radical cystectomy (odds ratio = 0.57; 95% confidence interval = 0.38-0.87; P < .05). Results from the 2-stages least squares regression approach suggested that receiving treatment in high-volume hospitals decreased the probability of in-hospital mortality by 0.02 points, compared with 0.01 points using the ordinary least squares regression approach. Outcomes following radical cystectomy appear to be driven by "practice makes perfect." PMID:22205768

    Introduction: Invasive cancer bladder is a life-threatening disease that is best treated with radical cystectomy and a suitable urinary diversion. The aim of this study was to evaluate the oncological outcome, voiding and sexual functions after genital sparing radical cystectomy with orthotopic bladder reconstruction in pre-menopausal women with bladder cancer. Materials and Methods: 18 pre-menopausal women who underwent radical cystectomy and orthotopic urinary diversion with preservation of genital organs were included for this study. The patients were followed-up clinically and radiologically to assess their oncological outcome in addition to their voiding and sexual function. Results: Mean age of the patients was 37.8 years, and the median follow-up after surgery was 70 months. One patient was lost to follow-up at 12 months post-operatively. The surgery was completed as planned in all patients, with a mean operative time of 290 min and an average blood loss of 750 mL. 14 patients were able to void satisfactorily, being continent day and night, while four patients needed clean intermittent catheterization. Sexual life remained unchanged in 15 cases, while three patients reported dysparunea. Till the last follow-up, there was no local recurrence while distant metastases were detected in three cases, two of whom died. Conclusions: Genital sparing cystectomy is a valid option for managing carefully selected women with muscle-invasive bladder cancer with good functional and sexual outcomes. PMID:26941498

    Objective To compare the long term impact on ovarian reserve between laparoscopic ovarian cystectomy with bipolar electrocoagulation and laparotomic cystectomy with suturing for ovarian endometrotic cyst. Patient and method(s) 121 patients with benign ovarian endometroitic cysts were randomised to either laparoscopic ovarian cystectomy using bipolar electrocoagulation (61 patients) or laparotomic ovarian cystectomy using sutures (60 patients). Serum follicle-stimulating hormone, Antimullerian hormon, Basal antral follicle Count, mean ovarian diameter, and ovarian stromal blood flow velocity were measured at 6, 12 and 18 months after surgery and compared in both groups. Result(s) A statistically significant increase of serum FSH was found in the laproscopic bipolar group at 6-, 12 and 18-month postoperativly compared to open laparotomy suture group. Also, a statistically significant decrease of the mean AMH value occurred in laproscopic bipolar group at 6-, 12 and 18-month follow- up compared to open laparotomy suture group. Basal antral follicle number, mean ovarian diameter and peak systolic velocity were significantly decreased during the 6-, 12,18 -month follow-up in laproscopic bipolar group compared to open laparotomy suture group. Conclusion(s) After laproscopic ovarian cystecomy for endometrioma all pareameter of ovarian reseve are significantly decreased on long term follow up as compared to open laprotomy. PMID:24180348

    Background and Objectives Use of patient-controlled epidural analgesia after various operations has been associated with earlier return of bowel function and thus decrease the length of stay (LOS). The primary aim of this study was to compare LOS after radical cystectomy between patients who received epidural analgesia versus those who received intravenous patient controlled analgesia. Our secondary analysis included the assessment of other metrics such as total opioid requirements, pain scores, return of bowel function and complication rates between the two groups. Methods We conducted a retrospective review using the electronic medical records of 308 patients who underwent radical cystectomies at Memorial Sloan Kettering between 2006 and 2011. We aimed to understand if epidural analgesia was associated with a reduced length of stay compared to patient controlled intravenous opioid analgesia. We also aimed to identify performance improvements as a function of epidural analgesia status using various metrics such as pain management, bowel function return, and complication rates. We used both univariate and multivariable analyses to identify if epidural analgesia was associated with meaningful differences in the aforementioned metrics. Results Median age at radical cystectomy, body mass index, sex, ASA score, and T stage were similar for both groups. For our primary objective of LOS, we found no significant difference between the two cohorts (8 vs 7 days, p=0.2). Analysis of our secondary outcome measures revealed that epidural analgesia use was associated with less total opioid requirement for the first three post-operative days (p=0.0001). Additionally, epidural analgesia was found to be associated with improved post-operative pain scores compared to intravenous patient-controlled analgesia on post-operative days 1 (p=0.0001) and 2 (p=0.004), and there was a slight improvement on post-operative day 3, but this was not significant (p=0.77). In contrast, we found no

    Background Pseudoaneurysms are caused by trauma, tumors, infections, vasculitis, atherosclerosis and iatrogenic complications. In this paper, we report about a patient with rupture of an external iliac artery pseudoaneurysm, which lead to hemorrhagic shock, after undergoing laparoscopic radical cystectomy and extended pelvic lymphadenectomy. Case presentation The patient was a 68-year-old Japanese male diagnosed with invasive bladder cancer. Laparoscopic radical cystectomy and extended pelvic lymphadenectomy were performed. On postoperative day 12, he developed a high fever and an acute inflammatory response with redness and swelling in the right inguinal region. He was diagnosed with necrotizing fasciitis and underwent debridement. On postoperative day 42, a sudden hemorrhage developed from the open wound in the right inguinal region. He was diagnosed with external iliac artery pseudoaneurysm rupture by computed tomography. Conclusion These complications occur extremely rarely after cystectomy with pelvic lymphadenectomy. There are no reports to date on these complications following laparoscopic cystectomy with pelvic lymphadenectomy. PMID:24885366

    One hundred eighty-three patients with bladder cancer category, T/sub 3/N/sub X/M/sub O/ (the diameter of the primary exceeding 5 cm), were treated by preoperative 40 Gy and simple cystectomy. Using only pretreatment information, the group with the best prognosis was characterized by a T/sub 3A/-growth with a normal intravenous pyelography, with a 75% cure rate. Before cystectomy, after irradiation the combination of clinically assessed radiation-downstaged growth (T/sub 40GY/<3) with normal urography, predicted the best chance of cure at about 80%. After cystectomy was performed, the best prognostic group could be most correctly identified: those patients with both microscopic downstaging of the primary (''P''/sub <3/) and no vascular invasion in the cystectomy specimen (CV - ) combined with normal urography had an 81% chance of cure. This most favorable group constitutes 45% of all patients.

After cystectomy was performed, the best prognostic group could be most correctly identified: those patients with both microscopic downstaging of the primary (''P''/sub <3/) and no vascular invasion in the cystectomy specimen (CV-) combined with normal urography had an 81% chance of cure. This most favorable group constitutes 45% of all patients.

    Abdominal wall metastasis from urothelial cancer is extremely rare and very few such cases have been reported in the literature. As such the treatment protocols are not so well defined. We present an interesting case of a 65-year-old male patient, known case of chronic kidney disease, who presented with a large, fungating infraumbilical mass 8 months postradical cystectomy. The mass involved full thickness anterior abdominal wall and small bowel including the ileal conduit. Wide excision of the mass along with adhered bowel loops and partial excision of the ileal conduit with right ureteric reimplant was performed. The large defect in the anterior abdominal wall was closed using a mesh (permanent with a bioresorbable coating inside) and myocutaneous thigh flap. The histopathological examination of the excised mass was consistent with secondary from the urothelial tumor. PMID:27453672

    The primary pancreatic hydatid (echinococcal) cyst is extremely rare with a reported incidence of <1%. Owing to its rareness and a considerable overlap of imaging features, a preoperative diagnosis is usually difficult. The dilemma in confirming this benign diagnosis has often questioned the extent of radical pancreatic resection. The involvement of pancreatic duct (cystopancreatic duct fistula) further complicates the management of such cystic lesions. In this report, we present a case of isolated hydatid cyst of the pancreatic body and tail communicating with the pancreatic duct. Cystogastrostomy preceded by partial cystectomy in the same setting has never been reported to date. The patient had an uneventful postoperative course and follow-up showed no evidence of cyst recurrence or dissemination. We consider this a safe surgical option in longstanding large cysts, especially if a cystopancreatic fistula is detected beforehand. The success of such a procedure however may rely on the size and thickness of the cyst wall to support this anastomosis. PMID:27512554

    We report three cases of light chain escape (LCE) at a single institution in Poland, including an interesting case of biclonal monoclonal gammopathy of undetermined significance (MGUS) that satisfied the criteria for progression to light chain multiple myeloma (LCMM) with a rapid rise in serum free light chain (FLC) levels, following steroidal treatment for simultaneous temporal artery inflammation and polymyalgia rheumatica (PMR). In the three cases discussed, progression of the disease by light chain escape was associated with rapid and severe renal impairment, highlighting the necessity for prompt detection of such free light chain-only producing clones in order to prevent the possible development of irreversible end-organ damage. Interestingly, monitoring of these three patients by serum free light chain assay (sFLC) and retrospective heavy/light chain analysis (HLC) detected this clonal evolution prior to clinical relapse and suggests that these assays represent important additional tools for more accurate monitoring of multiple myeloma patients.

    ABSTRACT Objective: This study reports the initial experience of extraperitoneal laparoscopic radical cystectomy (ELRC) and compared with transperitoneal laparoscopic radical cystectomy (TLRC) in the treatment of selected elderly bladder cancer patients. Patients and Methods: A total of forty male bladder cancer patients who underwent ELRC (n=19) or TLRC (n=21) with ureterocutaneostomy were investigated. Demographic parameters, perioperative variables, oncological outcomes and follow-up data were retrospectively analyzed. Results: A significantly shorter time to exsufflation (1.5±0.7 vs 2.1±1.1 d; p=0.026) and liquid intake (1.8±0.9 vs 2.8±1.9 d; p=0.035) were observed in the ELRC group compared with the TLRC group. The incidence of postoperative ileus in the ELRC group was lower than the TLRC group (0 vs 9.5%). However, the difference had no statistical significance (p>0.05). The removed lymph node number in the ELRC group was significantly lower than the TLRC group (p<0.001). No significant differences were observed between the two groups in the overall and cancer-free survival rates (p>0.05). Conclusions: ELRC seems to be a safe and feasible surgical strategy for the selected elderly bladder cancer patients with ≤ T2 disease. The surgical and oncological efficacy of the ELRC is similar to that of the TLRC, but with faster intestinal function recovery. Further studies with a large series including different urinary diversions are needed to confirm our results and to better evaluate the benefit of ELRC in bladder cancer patients. PMID:27564274

    Introduction: Radical cystectomy (RC) is the gold standard treatment for muscle-invasive bladder cancer. This procedure has a high rate of perioperative complications, many of which are infectious in nature. The objective of our study was to evaluate demographic, intrinsic and extrinsic patient variables associated with developing readmission within 30 days due to infectious complications following RC. Methods: We acquired data available from the American College of Surgeons National Surgical Quality Improvement Program. We queried this dataset to identify all patients who underwent RC for muscle-invasive malignant disease (CPT 188.x) in 2012 based on CPT coding. Logistic regression analysis was used to investigate the relationship between preoperative variables and readmissions for infectious complications. Results: Of the 961 patients undergoing cystectomy for malignancy, 159 (17%) required readmission for any indications at a median of 16 days (interquartile range 13–22 days) postoperatively. We identified 71 of a total of 159 (45%) readmissions, which were due to infectious complications. Smoking was more prevalent in the patient population readmitted for an infectious complication compared with the patient population readmitted for a non-infectious complication (37% versus 25%; p = 0.03). Using logistic regression analysis smoking was associated with a significant risk for readmission due to an infectious cause (odds ratio 2.28, 95% confidence interval 1.82–2.97, p = 0.02). Readmission due to an infectious etiology was not associated with other perioperative factors including type of urinary diversion, sex, duration of operation, hypertension, or recent weight loss. Conclusion: Readmission following RC is a common occurrence and infectious complications drive readmission in almost half of the cases. Current smoking was the only independent risk factor for an infectious readmission. Counseling patients in smoking cessation prior to the procedure may provide

  10. Febrile Urinary Tract Infection after Radical Cystectomy and Ileal Neobladder in Patients with Bladder Cancer

    PubMed Central

    2016-01-01

    Urinary tract infection (UTI) is one of the most common complications after radical cystectomy and orthotopic neobladder reconstruction. This study investigated the incidence and implicated pathogen of febrile UTI after ileal neobladder reconstruction and identify clinical and urodynamic parameters associated with febrile UTI. From January 2001 to May 2015, 236 patients who underwent radical cystectomy and ileal neobladder were included in this study. Fifty-five episodes of febrile UTI were identified in 46 patients (19.4%). The probability of febrile UTI was 17.6% and 19.8% at 6 months and 24 months after surgery, respectively. While, Escherichia coli was the most common implicated pathogen (22/55, 40.0%), Enterococcus spp. were the most common pathogen during the first month after surgery (18/33, 54.5%). In multivariate logistic regression analysis, ureteral stricture was an independent risk factor associated with febrile UTI (OR 5.93, P = 0.023). However, ureteral stricture accounted for only 6 episodes (10.9%, 6/55) of febrile UTI. Most episodes of febrile UTI occurred within 6 months after surgery. Thus, to identify risk factors associated with febrile UTI in the initial postoperative period, we assessed videourodynamics within 6 months after surgery in 38 patients. On videourodyamic examination, vesicoureteral reflux (VUR) was identified in 16 patients (42.1%). The rate of VUR presence in patients who had febrile UTI was not significantly different from those in patients without febrile UTI (50% vs. 39.3%, P = 0.556). Patients with febrile UTI had significantly larger residual urine volume (212.0 ± 193.7 vs. 90.5 ± 148.2, P = 0.048) than those without. E. coli and Enterococcus spp. are common pathogens and ureteral stricture and residual urine are risk factors for UTI after ileal neobladder reconstruction. PMID:27366009

    The purpose of the RAZOR (randomized open vs robotic cystectomy) study is to compare open radical cystectomy (ORC) vs robot-assisted RC (RARC), pelvic lymph node dissection (PLND) and urinary diversion for oncological outcomes, complications and health-related quality of life (HRQL) measures with a primary endpoint of 2-year progression-free survival (PFS). RAZOR is a multi-institutional, randomized, non-inferior, phase III trial that will enrol at least 320 patients with T1–T4, N0–N1, M0 bladder cancer with ≈160 patients in both the RARC and ORC arms at 15 participating institutions. Data will be collected prospectively at each institution for cancer outcomes, complications of surgery and HRQL measures, and then submitted to trial data management services Cancer Research and Biostatistics (CRAB) for final analyses. To date, 306 patients have been randomized and accrual to the RAZOR trial is expected to conclude in 2014. In this study, we report the RAZOR trial experimental design, objectives, data safety, and monitoring, and accrual update. The RAZOR trial is a landmark study in urological oncology, randomizing T1–T4, N0–N1, M0 patients with bladder cancer to ORC vs RARC, PLND and urinary diversion. RAZOR is a multi-institutional, non-inferiority trial evaluating cancer outcomes, surgical complications and HRQL measures of ORC vs RARC with a primary endpoint of 2-year PFS. Full data from the RAZOR trial are not expected until 2016–2017. PMID:25626182

    Purpose To investigate the serial changes of metabolic acidosis and identify associated risk factors in patients who underwent radical cystectomy and ileal neobladder. Material and Methods From January 2010 to August 2014, 123 patients who underwent radical cystectomy and ileal neobladder reconstruction for bladder cancer were included in this study. Metabolic acidosis was defined as a serum bicarbonate level less than 22 mEq/L and impaired renal function was defined as a GFR <50ml/min. The presence of metabolic acidosis was evaluated at 1 month, 1 year, and 2 years after surgery. Multivariate logistic regression analysis was conducted to identify risk factors associated with development of metabolic acidosis. Results Metabolic acidosis was observed in 52%, 19.5%, and 7.3% of patients at 1 month, 1 year, and 2 years after surgery, respectively. At 1 month after surgery, impaired renal function was the only independent risk factor associated with metabolic acidosis (OR 3.87, P = 0.046). At 1 year after surgery, diabetes was the only independent risk factor associated with metabolic acidosis (OR 5.68, P = 0.002). At 2 years post-surgery, both age and diabetes were significant risk factors associated with metabolic acidosis. Conclusion Approximately, half of patients experienced metabolic acidosis one month after ileal neobladder reconstruction. Preoperative impaired renal function was the most significant risk factor for developing metabolic acidosis in the early postoperative period. However, the incidence of metabolic acidosis decreased to less than 20% 1 year after surgery, and diabetes was an independent risk factor during this period. PMID:27384686

    This prospective study was conducted to assess the feasibility of laparoscopic cystectomy of an intact adnexal cyst performed inside a water proof endoscopic bag, aiming to avoid intraperitoneal spillage in case of cyst rupture. 102 patients were recruited. Two of them were pregnant. In 8 of the patients the lesions were bilateral, adding up to a total of 110 cysts involved in our study. The endoscopic sac did not rupture in any case. Mean diameter of the cysts was 5.7 cm (range: 2.3–10.5 cm). In 75/110 (68.2%) cases, cystectomy was completed without rupture, whereas in the remaining 35/110 (31.8%) cases the cyst ruptured. Minimal small spillage occurred despite every effort only in 8/110 (7.2%) cases with large (>8 cm) cystic teratomas. There were no intraoperative or postoperative complications. We concluded that laparoscopic cystectomy in-a-bag of an intact cyst is feasible and oncologically safe for cystic tumors with a diameter < 8 cm. Manipulation of larger tumors with the adnexa into the sac may be more difficult, and in such cases previous puncture and evacuation of the cyst contents should be considered. PMID:27099793

    Objective The effects of obesity in liver transplantation remain controversial. Earlier institutional data demonstrated no significant difference in postoperative complications or 1-year mortality. This study was conducted to test the hypothesis that obesity alone has minimal effect on longterm graft and overall survival. Methods A retrospective, single-institution analysis of outcomes in patients submitted to primary adult orthotopic liver transplantation was conducted using data for the period from 1 January 2002 to 31 December 2012. Recipients were divided into six groups by pre-transplant body mass index (BMI), comprising those with BMIs of <18.0 kg/m2, 18.0–24.9 kg/m2, 25.0–29.9 kg/m2, 30.0–35.0 kg/m2, 35.1–40.0 kg/m2 and >40 kg/m2, respectively. Pre- and post-transplant parameters were compared. A P-value of <0.05 was considered to indicate statistical significance. Independent predictors of patient and graft survival were determined using multivariate analysis. Results A total of 785 patients met the study inclusion criteria. A BMI of >35 kg/m2 was associated with non-alcoholic steatohepatitis (NASH) cirrhosis (P < 0.0001), higher Model for End-stage Liver Disease (MELD) score, and longer wait times for transplant (P = 0.002). There were no differences in operative time, intensive care unit or hospital length of stay, or perioperative complications. Graft and patient survival at intervals up to 3 years were similar between groups. Compared with non-obese recipients, recipients with a BMI of >40 kg/m2 showed significantly reduced 5-year graft (49.0% versus 75.8%; P < 0.02) and patient (51.3% versus 78.8%; P < 0.01) survival. Conclusions Obesity increasingly impacts outcomes in liver transplantation. Although the present data are limited by the fact that they were sourced from a single institution, they suggest that morbid obesity adversely affects longterm outcomes despite providing similar short-term results.

    Ileal conduit and neobladder urinary diversions are frequently performed after radical cystectomy. However, complications after radical cystectomy may be different according to the type of urinary diversion. Acute kidney injury (AKI) is a common complication after surgery and increases costs, morbidity, and mortality of hospitalized patients. This study was performed to compare the incidence of postoperative AKI between ileal conduit and neobladder urinary diversions after radical cystectomy.All consecutive patients who underwent radical cystectomy in 2004 to 2014 in a single tertiary care center were identified. The patients were divided into the ileal conduit and ileal neobladder groups. Preoperative variables, including demographics, cancer-related data and laboratory values, as well as intraoperative data and postoperative outcomes, including AKI, intensive care unit admission rate, and the duration of hospital stay, were evaluated between the groups. Postoperative AKI was defined according to the Kidney Disease: Improving Global Outcome criteria. Propensity score matching analysis was performed to reduce the influence of possible confounding variables and adjust for intergroup differences.After performing 1:1 propensity score matching, the ileal conduit and ileal neobladder groups each included 101 patients. The overall incidence of AKI after radical cystectomy was 30.7% (62 out of 202) and the incidences did not significantly differ between the groups (27 [26.7%], ileal conduit group vs 35 [34.7%], ileal neobladder group, P = 0.268). Intraoperative data, intensive care unit admission rate, and the duration of hospital stay were not significantly different between the groups.Postoperative AKI did not significantly differ between ileal conduit and neobladder urinary diversions after radical cystectomy. This finding provides additional information useful for appropriate selection of the urinary diversion type in conjunction with radical cystectomy. PMID:27603401

  16. RadioImmunotherapy for adenoid cystic carcinoma: a single-institution series of combined treatment with cetuximab

    PubMed Central

    2010-01-01

    Background Local control in adjuvant/definitive RT of adenoid cystic carcinoma (ACC) is largely dose-dependent. However, some clinical situations do not allow application of tumouricidal doses (i.e. re-irradiation) hence radiation sensitization by exploitation of high endothelial growth factor receptor (EGFR)-expression in ACC seems beneficial. This is a single-institution experience of combined radioimmunotherapy (RIT) with the EGFR-inhibitor cetuximab. Methods Between 2006 and 2010, 9 pts received RIT for advanced/recurrent ACC, 5/9 pts as re-irradiation. Baseline characteristics as well as treatment parameters were retrieved to evaluate efficacy and toxicity of the combination regimen were evaluated. Control rates (local/distant) and overall survival were calculated using Kaplan-Meier estimation. Results Median dose was 65 Gy, pts received a median of 6 cycles cetuximab. RIT was tolerated well with only one °III mucositis/dysphagia. Overall response/remission rates were high (77,8%); 2-year estimate of local control was 80% hence reaching local control levels comparable to high-dose RT. Progression-free survival (PFS) at 2 years and median overall survival were only 62,5% and 22,2 mo respectively. Conclusion While local control and treatment response in RIT seems promising, PFS and overall survival are still hampered by distant failure. The potential benefit of RIT with cetuximab warrants exploration in a prospective controlled clinical trial. PMID:21047402

    Objective: To assess the clinical utility and efficiency of transumbilical multiport laparoscopic nephroureterectomy (TMLN) for the treatment of congenital renal dysplasia in children by analyzing consecutive cases from a single institution. Methods: Sixteen children underwent TMLN procedure due to dysplastic kidney between January 2010 and December 2011. The surgery was transperitoneally performed through three transumbilical incisions for two 5-mm and one 3-mm ports, which duplicated the standard laparoscopic steps with the usual laparoscopic instruments. Demographic, perioperative, and follow-up data were analyzed. Results: TMLN was performed in all patients, without additional ports or conversion to open surgery. The mean operation time was 108.4 min (range 90–125), and the blood loss was minimal. There were no severe intraoperative or post-operative complications. The post-operative recovery was uneventful in all patients. No urinary incontinence or umbilical hernias occurred. The cosmetic result was excellent as the incision scar was hidden inside the belly button. Conclusion: TMLN is a safe and efficient procedure for the management of congenital renal dysplasia in children with good cosmesis. Future randomized studies with a larger number of cases and a longer follow-up are warranted to elucidate the benefits and limitations of TMLN in children. PMID:24400291

    2011-01-01

    Background The subtype distribution of lymphoid neoplasms in Southwest China was analyzed according to WHO classifications. This study aims to analyze subtype distribution of lymphomas in southwest China. Methods Lymphoid neoplasms diagnosed within 9 years in a single institution in Southwest China were analyzed according to the WHO classification. Results From January 2000 to December 2008, a total number of 6,382 patients with lymphoma were established, of which mature B-cell neoplasms accounted for 56%, mature T- and NK-cell neoplasms occupied 26%, and precursor lymphoid neoplasms and Hodgkin lymphomas were 5% and 13%, respectively. Mixed cellularity (76%) was the major subtype of classical Hodgkin lymphoma; and the bimodal age distribution was not observed. The top six subtypes of non-Hodgkin lymphoma were as follows: diffuse large B-cell lymphoma, extranodal NK/T-cell lymphoma, nasal type, extranodal marginal zone lymphoma of mucosa associated lymphoid tissue, follicular lymphoma, precursor lymphoid neoplasms, and chronic lymphocytic leukemia/small lymphocytic lymphoma. Extranodal lymphomas comprised about half of all cases, and most frequently involved Waldeyer's ring, gastrointestinal tract, sinonasal region and skin. Conclusions The lymphoid neoplasms of Southwest China displayed some epidemiologic features similar to those reported in literature from western and Asian countries, as well as other regions of China, whereas some subtypes showed distinct features. The high frequency of mature T/NK cell neoplasms and extranodal lymphomas, especially for extranodal NK/T-cell lymphoma, nasal type, is the most outstanding characteristic of this series.

    Rituximab (RTX) improves the outcome in patients with systemic diffuse large B-cell lymphoma (DLBCL), but its benefit in primary central nervous system lymphoma (PCNSL) is unclear. In the present study, a single-institution retrospective analysis was performed for 12 patients with newly diagnosed PCNSL treated with combined high-dose methotrexate (HD-MTX) and RTX. MTX was administered biweekly at 8 g/m2/dose until a complete response (CR) was achieved or for a maximum of eight doses. RTX was provided for a total of eight weekly doses at 375 mg/m2/dose. Following a median of 11 cycles of MTX, the radiographic overall response rate was 91% and the CR rate was 58%. A CR was achieved after a median 6 cycles of MTX. The median progression-free survival time was 22 months and the median overall survival time has not yet been attained. These results compare favorably to single-agent HD-MTX and suggest a role for immunochemotherapy in the treatment of PCNSL. PMID:27123138

    The long-term urodynamics of laparoscopic radical cystectomy with orthotopic ileal neobladder for bladder cancer remain unclear in the clinical setting. The present prospective observational study was conducted between January 2010 and December 2012 to evaluate the 6-month and 12-month follow-up data of urodynamic changes of bladder cancer patients who were initially treated by laparoscopic radical cystectomy with orthotopic ileal neobladder. A total of 53 eligible patients were included, and all patients were followed up for at least 12 months, with a median time of 18 months. During the follow-up period, no patients reported difficulty urinating, and the daily frequency of urination and the urine output were gradually improved with time. Dynamic urodynamic examinations showed that the maximum flow rate (11.4±1.1 vs. 7.3±1.4 ml/sec; P<0.001), residual urine content (22.8±10.5 vs. 40.7±12.7 ml; P<0.001), maximum bladder capacity (373.8±62.2 vs. 229.7±56.3 ml; P<0.001) and maximum bladder pressure during filling (35.8±6.7 vs. 26.4±7.0 cm H2O; P<0.001) at 12 months were all improved significantly compared with that at 6 months after the initial surgical treatment. However, there were no significant differences in maximum bladder pressure during voiding (75.7±24.7 vs. 73.1±24.7 cm H2O; P=0.618) and bladder compliance (26.9±13 vs. 27.4±13.1 cm H2O; P=0.848) at 12 and 6 months after initial surgical treatment. In conclusion, the urodynamics of this orthotopic ileal neobladder gradually improve, and its long-term urine storage and voiding functions are acceptable. PMID:25120652

    The aim of the present systematic review was to study the effect of bipolar electrocoagulation during ovarian cystectomy on ovarian reserve. We searched Medline (1966-2015), Scopus (2004-2015), ClinicalTrials.gov (2008-2015), and Cochrane Central Register (CENTRAL) databases along with reference lists of electronically retrieved studies. The levels of antimullerian hormone (AMH) and antral follicle count (AFC) at 1, 3, 6, and 12 months following the excision of the benign ovarian cyst were defined as primary outcomes. Eight studies were finally included in our systematic review, which recruited 545 women. A metaanalysis was precluded because of significant heterogeneity in the methodological characteristics of the included studies. Data from the included studies suggest that the use of bipolar coagulation compared with ovarian sutures seems to result in significantly lower AMH and AFC during the first 3 months following the excision of the ovarian cyst. Two studies reported that this effect seems to persist at 6 and 12 months postoperatively. Bipolar electrodiathermy seems to be accompanied by increased damage to ovarian reserve, which is indicated by the lower levels of AMH and AFC. However, definitive results are precluded because of the significant heterogeneity of included studies and the potential bias. PMID:25882917

    Summary Objective To evaluate predictors of understaging in patients with presumed non-muscle invasive bladder cancer (NMIBC) identified on transurethral resection of bladder tumor (TURBT) who underwent radical cystectomy (RC) with attention to the role of a restaging TURBT. Materials and Methods We retrospectively evaluated 279 consecutive patients with clinically staged T1 (cT1) disease following TURBT who underwent RC at our institution from April 2000 to July 2011. 60 of these cT1 patients had undergone a restaging TURBT prior to RC. The primary outcome measure was pathological staging of T2 or greater disease at the time of RC. Results 134 (48.0%) patients were understaged. Of the 60 patients who remained cT1 after a restaging TURBT, 28 (46.7%) were understaged. Solitary tumor (OR 0.43, 95% CI 0.25–0.76, p = 0.004) and fewer prior TURBTs (OR 0.84, 95% CI 0.71–1.00, p = 0.05) were independent risk factors for understaging. Conclusions Despite the overall improvement in staging accuracy linked to restaging TURBTs, the risk of clinical understaging remains high in restaged patients found to have persistent T1 urothelial carcinoma who undergo RC. Solitary tumor and fewer prior TURBTs are independent risk factors for being understaged. Incorporating these predictors into preoperative risk stratification may allow for augmented identification of those patients with clinical NMIBC who stand to benefit most from RC. PMID:24053444

    The purpose of this case report is to discuss the positive impact of a multimodal prehabilitation program on postoperative recovery of a frail patient undergoing radical cystectomy. An 85-year-old man with significant history for poorly controlled type II diabetes, anemia, chronic renal failure, and glaucoma was found to have muscle invasive urothelial carcinoma of the bladder with hydronephrosis. He was scheduled for elective radical cystoprostatectomy and ileal conduit diversion. He was enrolled in a multimodal prehabilitation program in view of his frailty (Fried score = 5), 15% body weight loss, weak grip strength, severe depression and moderate anxiety, poor nutritional status (patient-generated subjective global assessment [PG-SGA] = B), low functional walking capacity (6-minute walking test [6MWT] = 210 metres, predicted 621 metres). The 4-week program included moderate aerobic and resistant exercises, nutritional counselling with whey protein supplementation (20 g/day), and relaxation exercises. Surgery and the postoperative period were uneventful, although he required treatment of his hyperglycemia and hypomagnesemia. He left the hospital on postoperative day 7 and returned home where he continued the multimodal program for 8 weeks. Measurements of 6MWT, Health-Related Quality of Life (SF-36), physical activity, Hospital Anxiety and Depression Scale (HADS), were conducted at baseline, before surgery and at 4 and 8 weeks after surgery. These tests revealed a progressive remarkable improvement before surgery that continued after surgery. PMID:25485023

    Purpose: To evaluate our long-term results of bladder preservation with brachytherapy in the treatment of bladder cancer. Methods and materials: Between 1987 and 2000, 108 patients with T1-G3 and T2-T3a stages of bladder cancer were treated with a transurethral resection (TUR) and a course of external beam radiotherapy (30 Gy in 15 fractions) followed by brachytherapy (40 Gy). All tumors were solitary lesions with a diameter {<=}5 cm. Median follow-up was 54 months (range, 1-178 months). Results: The 5-year and 10-year overall survival rates were 62% and 50%, respectively. The 5-year and 10-year disease-specific survival rates were 73% and 67%, respectively. The actuarial local control rate was 73% at 5 and 73% at 10 years, respectively. The 5-year and 10-year disease-specific survival rates for patients with a preserved bladder were 68% and 59%, respectively. Of all long-term surviving patients, 90% preserved their native bladders. The treatment was well tolerated. Acute toxicity was mild. Two patients experienced serious late toxicity: 1 patient developed a persisting vesicocutaneous fistula and the other a stricture of the urethra and ureters. Conclusion: For patients with solitary, organ confined invasive bladder cancer {<=}5 cm, bladder preservation with brachytherapy is an excellent alternative to radical cystectomy and combined modality treatment.

    Aim To describe daily displacements when using fiducial markers as surrogates for the target volume in patients with prostate cancer treated with IGRT. Background The higher grade of conformity achieved with the use of modern radiation technologies in prostate cancer can increase the risk of geographical miss; therefore, an associated protocol of IGRT is recommended. Materials and methods A single-institution, retrospective, consecutive study was designed. 128 prostate cancer patients treated with daily on-line IGRT based on 2D kV orthogonal images were included. Daily displacement of the fiducial markers was considered as the difference between the position of the patient when using skin tattoos and the position after being relocated using fiducial markers. Measures of central tendency and dispersion were used to describe fiducial displacements. Results The implant itself took a mean time of 15 min. We did not detect any complications derived from the implant. 4296 sets of orthogonal images were identified, 128 sets of images corresponding to treatment initiation were excluded; 91 (2.1%) sets of images were excluded from the analysis after having identified that these images contained extreme outlier values. If IGRT had not been performed 25%, 10% or 5% of the treatments would have had displacements superior to 4, 7 or 9 mm respectively in any axis. Conclusions Image guidance is required when using highly conformal techniques; otherwise, at least 10% of daily treatments could have significant displacements. IGRT based on fiducial markers, with 2D kV orthogonal images is a convenient and fast method for performing image guidance. PMID:25535583

    Chromosomal rearrangements affecting the MLL gene are associated with high-risk pediatric, adult and therapy-associated acute leukemia. In this study, conventional cytogenetic, fluorescence in situ hybridization, and molecular genetic studies were used to characterize the type and frequency of MLL rearrangements in a consecutive series of 45 Portuguese patients with MLL-related leukemia treated in a single institution between 1998 and 2011. In the group of patients with acute lymphoblastic leukemia and an identified MLL fusion partner, 47% showed the presence of an MLL-AFF1 fusion, as a result of a t(4;11). In the remaining cases, a MLL-MLLT3 (27%), a MLL-MLLT1 (20%), or MLL-MLLT4 (7%) rearrangement was found. The most frequent rearrangement found in patients with acute myeloid leukemia was the MLL-MLLT3 fusion (42%), followed by MLL-MLLT10 (23%), MLL-MLLT1 (8%), MLL-ELL (8%), MLL-MLLT4 (4%), and MLL-MLLT11 (4%). In three patients, fusions involving MLL and a septin family gene (SEPT2, SEPT6, and SEPT9), were identified. The most frequently identified chromosomal rearrangements were reciprocal translocations, but insertions and deletions, some cryptic, were also observed. In our series, patients with MLL rearrangements were shown to have a poor prognosis, regardless of leukemia subtype. Interestingly, children with 1 year or less showed a statistically significant better overall survival when compared with both older children and adults. The use of a combined strategy in the initial genetic evaluation of acute leukemia patients allowed us to characterize the pattern of MLL rearrangements in our institution, including our previous discovery of two novel MLL fusion partners, the SEPT2 and CT45A2 genes, and a very rare MLL-MLLT4 fusion variant.

    The global emergence of Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-Kp) multilocus sequence type ST258 is widely recognized. Less is known about the molecular and epidemiological details of non-ST258 K. pneumoniae in the setting of an outbreak mediated by an endemic plasmid. We describe the interplay of blaKPC plasmids and K. pneumoniae strains and their relationship to the location of acquisition in a U.S. health care institution. Whole-genome sequencing (WGS) analysis was applied to KPC-Kp clinical isolates collected from a single institution over 5 years following the introduction of blaKPC in August 2007, as well as two plasmid transformants. KPC-Kp from 37 patients yielded 16 distinct sequence types (STs). Two novel conjugative blaKPC plasmids (pKPC_UVA01 and pKPC_UVA02), carried by the hospital index case, accounted for the presence of blaKPC in 21/37 (57%) subsequent cases. Thirteen (35%) isolates represented an emergent lineage, ST941, which contained pKPC_UVA01 in 5/13 (38%) and pKPC_UVA02 in 6/13 (46%) cases. Seven (19%) isolates were the epidemic KPC-Kp strain, ST258, mostly imported from elsewhere and not carrying pKPC_UVA01 or pKPC_UVA02. Using WGS-based analysis of clinical isolates and plasmid transformants, we demonstrate the unexpected dispersal of blaKPC to many non-ST258 lineages in a hospital through spread of at least two novel blaKPC plasmids. In contrast, ST258 KPC-Kp was imported into the institution on numerous occasions, with other blaKPC plasmid vectors and without sustained transmission. Instead, a newly recognized KPC-Kp strain, ST941, became associated with both novel blaKPC plasmids and spread locally, making it a future candidate for clinical persistence and dissemination.

    Purpose: To evaluate and compare outcomes for patients with vestibular schwannoma (VS) treated in a single institution with linac-based stereotactic radiosurgery (SRS) or by fractionated stereotactic radiotherapy (SRT). Methods and Materials: One hundred and nineteen patients (SRS = 78, SRT = 41) were treated. For both SRS and SRT, beam shaping is performed by a mini-multileaf collimator. For SRS, a median single dose of 12.5 Gy (range, 11-14 Gy), prescribed to the 80% isodose line encompassing the target, was applied. Of the 42 SRT treatments, 32 treatments consisted of 10 fractions of 3-4 Gy, and 10 patients received 25 sessions of 2 Gy, prescribed to the 100% with the 95% isodose line encompassing the planning target volume. Mean largest tumor diameter was 16.6 mm in the SRS and 24.6 mm in the SRT group. Local tumor control, cranial nerve toxicity, and preservation of useful hearing were recorded. Any new treatment-induced cranial nerve neuropathy was scored as a complication. Results: Median follow-up was 62 months (range, 6-136 months), 5 patients progressed, resulting in an overall 5-year local tumor control of 95%. The overall 5-year facial nerve preservation probability was 88% and facial nerve neuropathy was statistically significantly higher after SRS, after prior surgery, for larger tumors, and in Koos Grade {>=}3. The overall 5-year trigeminal nerve preservation probability was 96%, not significantly influenced by any of the risk factors. The overall 4-year probability of preservation of useful hearing (Gardner-Robertson score 1 or 2) was 68%, not significantly different between SRS or SRT (59% vs. 82%, p = 0.089, log rank). Conclusion: Linac-based RT results in good local control and acceptable clinical outcome in small to medium-sized vestibular schwannomas (VSs). Radiosurgery for large VSs (Koos Grade {>=}3) remains a challenge because of increased facial nerve neuropathy.

    Background and Purpose This study evaluated the outcome following surgery for carotid artery stenosis in a single institution during a 10-year period and the relevance of aging to access to surgery. Methods Between January 2001 and December 2010, 649 carotid endarterectomies (CEAs) were performed in 596 patients for internal carotid artery occlusive disease at our institution; 596 patients received unilateral CEAs and 53 patients received bilateral CEAs. Data regarding patient characteristics, comorbidities, stroke, mortality, restenosis, and other surgical complications were obtained from a review of medical records. Since elderly and high-risk patients comprise a significant proportion of the patient group undergoing CEAs, differences in comorbidity and mortality were evaluated according to age when the patients were divided into three age groups: <70 years, 70-79 years, and ≥80 years. Results The mean age of the included patients was 67.5 years, and 88% were men. Symptomatic carotid stenosis was observed in 65.7% of patients. The rate of perioperative stroke and death (within 30 days of the procedure) was 1.84%. The overall mortality rate was higher among patients in the 70-79 years and >80 years age groups than among those in the <70 years age group, but there was no significant difference in stroke-related mortality among these three groups. Conclusions CEA over a 10-year period has yielded acceptable outcomes in terms of stroke and mortality. Therefore, since CEA is a safe and effective strategy, it can be performed in elderly patients with acceptable life expectancy. PMID:26754779

    Purpose: Anatomic changes and positional variability during intensity-modulated radiation therapy (IMRT) for head and neck cancer can lead to clinically significant dosimetric changes. We report our single-institution experience using an adaptive protocol and correlate these changes with anatomic and positional changes during treatment. Methods and Materials: Twenty-three sequential head and neck IMRT patients underwent serial computed tomography (CT) scans during their radiation course. After undergoing the planning CT scan, patients underwent planned rescans at 11, 22, and 33 fractions; a total of 89 scans with 129 unique CT plan combinations were thus analyzed. Positional variability and anatomic changes during treatment were correlated with changes in dosimetric parameters to target and avoidance structures between planning CT and subsequent scans. Results: A total of 15/23 patients (65%) benefited from adaptive planning, either due to inadequate dose to gross disease or to increased dose to organs at risk. Significant differences in primary and nodal targets (planning target volume, gross tumor volume, and clinical tumor volume), parotid, and spinal cord dosimetric parameters were noted throughout the treatment. Correlations were established between these dosimetric changes and weight loss, fraction number, multiple skin separations, and change in position of the skull, mandible, and cervical spine. Conclusions: Variations in patient positioning and anatomy changes during IMRT for head and neck cancer can affect dosimetric parameters and have wide-ranging clinical implications. The interplay between random positional variability and gradual anatomic changes requires careful clinical monitoring and frequent use of CT- based image-guided radiation therapy, which should determine variations necessitating new plans.

    The aim of this single-institutional 10-year retrospective study was to investigate the clinical pattern (incidence, type, timing, and location) of venous thromboembolism (VTE) in Chinese patients with gynecologic cancer. Cases were identified by searching institutional Electronic Discharge Database. A comprehensive review of medical documentation was then performed to collect relevant data. The detection of VTE was symptom-triggered. A total of 155 VTE events were identified out of 7562 cases over the past 10-year period in our hospital. The incidence of clinically significant VTE was 2.0% in gynecologic malignancy, with vulvar cancer (3.7%) and ovarian cancer (2.5%) being the high-risk types (P = 0.01, Chi-square test). Perioperative period (35.1%) and preoperation (29.1%) were the 2 incidence peaks. Seventeen cases of pulmonary embolism (PE) occurred prior to surgery. Ovarian cancer patients were more likely to present preoperative PE compared to other site of cancer (76.4%; P = 0.01, Chi-square test). More preoperative VTE cases were complicated by PE than those in the perioperative period (39.5% vs 17.3%, P = 0.02, Chi-square test). Bilateral lower extremity deep vein thrombosis (DVT) accounted for 32.6% and there existed a preponderance of left-sided DVT (47.5% vs 17.0%, ratio 2.79:1). Femoral vein (36.6%) was the most common location for DVT. About 2.0% of the Chinese patients with gynecologic carcinoma developed clinical VTE, mostly during perioperative period and the time of diagnosis. The true incidence might have been under-estimated due to several reasons. The need for increased patient education and awareness of VTE is of importance. PMID:26683971

    Objective Chronic subdural hematoma has an increasing incidence and results in high morbidity and mortality. We review here the ten-year experience of a single institution and the literature regarding the treatment and major associations of chronic subdural hematoma (cSDH). Methods We retrospectively reviewed all cSDHs surgically treated from 2000 to 2010 at our institution to evaluate duration from admission to treatment, type of treatment, length of stay in critical care, length of stay in the hospital and recurrence. The literature was reviewed with regards to incidence, associations and treatment of cSDH. Results From 2000–2008, 44 patients were treated with burr holes. From 2008 to 2010, 29 patients were treated with twist drill evacuation (SEPS). 4 patients from each group were readmitted for reoperation (9% vs. 14%; p=.53). The average time to intervention for SEPS (11.2±15.3 hrs) was faster than for burr holes (40.3±69.1 hrs) (p=.02). The total hospital LOS was shorter for SEPS (9.3±6.8 days) versus burr holes (13.4±10.2 days) (p=.04); both were significantly longer than for a brain tumor patient undergoing craniotomy (7.0±0.5 days, n=94, P<.01). Conclusion Despite decreasing lengths of stay over time as treatment for cSDH evolved from burr holes to SEPS, the length of stay for a cSDH is still greater than that of a patient undergoing craniotomy for brain tumor. We noted 11% recurrence in our series of patients, which included individuals who recurred as late as 3 years after initial diagnosis. PMID:23485050

    To review cases of simultaneous radical cystectomy and colorectal cancer (CRC) resection for synchronous carcinoma of bladder and colorectum. Between May 1997 and September 2010, five patients were diagnosed with synchronous bladder cancer and CRCs. The primary colorectal tumors included three sigmoid cancers, one ascending colon cancer and one rectal cancer. All patients underwent simultaneous radical cystectomy and CRC resection. Pathologic types were confirmed by the biopsies of cystoscopy and colonoscopy. All patients were performed synchronous radical cystectomy and CRC resection. Four of them received adjuvant chemotherapies for CRC. Two of them died of liver metastasis 32.8 months and 13 months after surgery. Although patients with synchronous carcinoma of bladder and colorectum are rare, the Urologist should be alerted to this possibility when evaluating patients for the initially presenting symptoms and/or detected tumors. The simultaneous surgery is technically feasible for the selected patients. PMID:25538788

    Abstract Background: Women who undergo cystectomy with orthotopic ileal neobladder are more likely to have urinary retention and neocystocele mainly because of anatomical reasons than stress urinary incontinence. The risk is even higher in case of neurologic comorbidities, as in case of our patient. Case Presentation: We present a laparoscopic mesh insertion for sacrospinal colposuspension to prevent a neocystocele and pelvic organ prolapse in combination with laparoscopic radical cystectomy in a female patient suffering from bladder cancer and chronic episodic multiple sclerosis. After a 30-month follow-up, the patient is continent and voids without residual urine. A dynamic MR of the pelvis shows a minimal rectocele without any evidence of a cystocele. Conclusion: Laparoscopic cystectomy combined with sacrospinal mesh fixation is technically feasible and could be an option to prevent neocystocele for female patients.

    AIM: To evaluate the prognostic factors of hilar cholangiocarcinoma in a large series of patients in a single institution. METHODS: Eight hundred and fourteen patients with a diagnosis of hilar cholangiocarcinoma that were evaluated and treated between 1990 and 2014, of which 381 patients underwent curative surgery, were included in this study. Potential factors associated with overall survival (OS) and disease-free survival (DFS) were evaluated by univariate and multivariate analyses. RESULTS: Curative surgery provided the best long-term survival with a median OS of 26.3 mo. The median DFS was 18.1 mo. Multivariate analysis showed that patients with tumor size > 3 cm [hazard ratio (HR) = 1.482, 95%CI: 1.127-1.949; P = 0.005], positive nodal disease (HR = 1.701, 95%CI: 1.346-2.149; P < 0.001), poor differentiation (HR = 2.535, 95%CI: 1.839-3.493; P < 0.001), vascular invasion (HR = 1.542, 95%CI: 1.082-2.197; P = 0.017), and positive margins (HR = 1.798, 95%CI: 1.314-2.461; P < 0.001) had poor OS outcome. The independent factors for DFS were positive nodal disease (HR = 3.383, 95%CI: 2.633-4.348; P < 0.001), poor differentiation (HR = 2.774, 95%CI: 2.012-3.823; P < 0.001), vascular invasion (HR = 2.136, 95%CI: 1.658-3.236; P < 0.001), and positive margins (HR = 1.835, 95%CI: 1.256-2.679; P < 0.001). Multiple logistic regression analysis showed that caudate lobectomy [odds ratio (OR) = 9.771, 95%CI: 4.672-20.433; P < 0.001], tumor diameter (OR = 3.772, 95%CI: 1.914-7.434; P < 0.001), surgical procedures (OR = 10.236, 95%CI: 4.738-22.116; P < 0.001), American Joint Committee On Cancer T stage (OR = 2.010, 95%CI: 1.043-3.870; P = 0.037), and vascular invasion (OR = 2.278, 95%CI: 0.997-5.207; P = 0.051) were independently associated with tumor-free margin, and surgical procedures could indirectly affect survival outcome by influencing the tumor resection margin. CONCLUSION: Tumor margin, tumor differentiation, vascular invasion, and lymph node status were independent

    Purpose: To evaluate the predictive accuracy and general applicability of the locoregional failure model in a different cohort of patients treated with radical cystectomy. Methods and Materials: A total of 398 patients were included in the analysis. Death and isolated distant metastasis were considered competing events, and patients without any events were censored at the time of last follow-up. The model included the 3 variables pT classification, the number of lymph nodes identified, and margin status, as follows: low risk (≤pT2), intermediate risk (≥pT3 with ≥10 nodes removed and negative margins), and high risk (≥pT3 with <10 nodes removed or positive margins). Results: The bootstrap-corrected concordance index of the model 5 years after radical cystectomy was 66.2%. When the risk stratification was applied to the validation cohort, the 5-year locoregional failure estimates were 8.3%, 21.2%, and 46.3% for the low-risk, intermediate-risk, and high-risk groups, respectively. The risk of locoregional failure differed significantly between the low-risk and intermediate-risk groups (subhazard ratio [SHR], 2.63; 95% confidence interval [CI], 1.35-5.11; P<.001) and between the low-risk and high-risk groups (SHR, 4.28; 95% CI, 2.17-8.45; P<.001). Although decision curves were appropriately affected by the incidence of the competing risk, decisions about the value of the models are not likely to be affected because the model remains of value over a wide range of threshold probabilities. Conclusions: The model is not completely accurate, but it demonstrates a modest level of discrimination, adequate calibration, and meaningful net benefit gain for prediction of locoregional failure after radical cystectomy.

    Background: To identify potential avenues for quality improvement, we compared the variations in clinical practice and their association with perioperative morbidity and mortality following radical cystectomy (RC) for bladder cancer in the United States (US) and Japan. Methods: We reviewed our retrospectively collected database of 2240 patients who underwent RC for bladder cancer at the University of Michigan (n = 1427) and in 21 Japanese institutions (n = 813) between 1997 and 2014. We performed a systematic comparison of clinical and perioperative factors and assessed predictors of perioperative morbidity and mortality. Death within 90 days of surgery was the primary outcome. Results: There were apparent differences between the two study populations. Notably, US patients had a significantly greater BMI and higher ASA score. In Japanese institutions, median postoperative hospital stay was significantly higher (40 days vs. 7 days, p <  0.001) and 90-day readmission rates were significantly lower (0.6% vs. 26.8% , p <  0.001). There was a total of 1372/2240 (61.2%) patients with complications within 90 days and 66/2240 (2.9%) patient deaths. Significant predictors of 90-day mortality were older age (OR 1.04, CI 1.01–1.07), higher body mass index (OR 1.07, CI 1.02–1.12), node-positive disease (OR 3.14, CI 1.78–5.47), increased blood loss (OR 1.02, CI 1.01–1.03), and major (Clavien-grade 3 or greater) complication (OR 3.29, CI 1.88–5.71). Conclusion: Despite major differences in baseline characteristics and care of cystectomy patients between the two study populations, peri-operative mortality rates proved to be comparable. This data supports an exploration of non-traditional factors that may influence mortality after cystectomy. PMID:27376144

    Objective: The purpose of the study was to evaluate the neuroprotective effect of dexmedetomidine on anesthesia recovery period and postoperative cognitive function of patients after robot-assisted laparoscopic radical cystectomy and ileal conduit diversion. Methods: A total of 40 elective patients who would undergo robot-assisted laparoscopic radical cystectomy and ileal conduit diversion. They were randomly divided into two groups in a double-blind manner. After pneumoperitoneum established, all patients adopted 40° trendelenberg position. Mean arterial pressure (MAP), heart rate (HR), and bispectral index (BIS) of each patient were recorded at four moments respectively, namely the end of surgery (T0), palinesthesia (T1), extubation (T2), 10 min after extubation (T3). Results: In the dexmedetomidine group, the mean arterial pressure and heart rate decreased at T1 and T2 compared with controls (P<0.05); in addition, the delirium rating scale was lower than the latter (P<0.05) while Ramsay sedation score was significantly higher (P<0.05). POCD was observed on 28 patients, containing 17 controls and 11 dexmedetomidine individuals, one day after operation, and 21 patients (12 controls, 9 dexmedetomidine people) five days after operation. One- and five-day after operation, the levels of TNF-α, NSE and IL-6 in the dexmedetomidine group were significantly lower than those in the control group (P<0.05), and serum SOD significantly increased in the former (P<0.05). Conclusion: Dexmedetomidine had a neuroprotective effect on anesthesia recovery and postoperative period of the elderly patients undergone robot-assisted laparoscopic radical cystectomy, which might be related to the reduction of inflammatory reaction induced by dexmedetomidine.

    Introduction Our objective is to assess differences in practice patterns and outcomes across 3 regions in bladder cancer patients treated with radical cystectomy under a universal healthcare system. Methods: In total, we included 2287 patients treated with radical cystectomy at 8 Canadian centres from 1998 to 2008. Variables included various clinico-pathologic parameters, recurrence, and death stratified into different regions. Results: In total, 1105 patients were from the east region (group 1), 601 from the centre region (group 2), and 581 from the west region of Canada (group 3). The median follow-up of groups 1, 2, and 3 was 22.1, 17.1, and 28.6 months, respectively. Although the overall rate of neoadjuvant chemotherapy was low (3.1%), rates were higher in group 2 compared with groups 1 and 3 (p = 0.07). Continent diversions and extended lymphadenectomy were performed in 23.5%, 8.5%, 23.9% and 39.7%, 27.7%, 12.6% across groups 1, 2, and 3, respectively. There were statistically significant differences in gender distribution, performance of lymphadenectomy, presence of concomitant carcinoma in situ and lymphovascular invasion across the 3 groups. There were no differences among the 3 geographical locations in terms of stage, surgical margin status, and use of adjuvant chemotherapy. The mean number of days from the transurethral resection of the bladder tumour to cystectomy was 50, 79, 69 days for groups 1, 2, 3, respectively (p = 0.0006). The 5-year overall survival was 53.6%, 66.8%, and 52.4% for groups 1, 2 and 3, respectively (p < 0.0001). Conclusions: Significant variations in practice patterns were noted across different geographic regions in a universal healthcare system. Use of continent diversions, extended lymphadenectomy, and neoadjuvant chemotherapy remains low across all 3 regions. Treatment delays are significant. PMID:24282454

    Revision rhinoplasty is one of the most challenging operations the facial plastic surgeon performs given the complex 3-dimensional anatomy of the nose and the psychological impact it has on patients. The intricate interplay of cartilages, bone, and soft tissue in the nose gives it its aesthetic and function. Facial harmony and attractiveness depends greatly on the nose given its central position in the face. In the following article, the authors review common motivations and anatomic findings for patients seeking revision rhinoplasty based on the senior author's 30-year experience with rhinoplasty and a review of the literature.

    Introduction: In 1971, the National Cancer Institute (NCI) introduced a network of NCI-designated Cancer Centers (CC), which underwent a comprehensive approval process relying on research, education and prevention activities. In this study, we examine the effect of CC status on perioperative outcomes after radical cystectomy (RC). Methods: Within the Nationwide Inpatient Sample, we focused on RC performed from 2006 to 2010. As all recognized centres were residency teaching institutions, we stratified according to teaching and CC-teaching status. We examined the rates of in-hospital mortality, intra- and postoperative complications, prolonged length of hospital stay, as well as blood transfusion. Multivariable logistic regression analyses were further adjusted for confounding factors. Results: Overall, 22 840 RC patients (5451 at non-teaching, 10 857 at residency teaching, 6532 at CC-teaching institutions) were identified. Patients treated at residency teaching and CC-teaching institutions were younger, had less comorbidities, and more likely to have private insurance. In multivariable analyses, patients treated at residency and CC-teaching institutions were less likely to experience postoperative complications (odds ratio [OR] 0.73 and 0.66, respectively) and blood transfusions (OR 0.77 and 0.53, respectively) relative to patients treated at non-teaching institutions. In addition, CC patients were also less likely to experience in-hospital mortality (OR 0.61, all p < 0.001) as compared to non-teaching institutions. Conclusions: On average, patients treated at residency and CC-teaching institutions are less likely to experience unfavourable outcomes after RC. Moreover, patients treated at CC fared better than patients treated at residency teaching institutions. Our findings acknowledge the quality of RC care at accredited centres. PMID:26225174

    Background: The objective of this study was to examine the rates of blood transfusions, prolonged length of stay, intraoperative and postoperative complications, as well as in-hospital mortality, stratified according to institutional academic status in patients undergoing radical cystectomy (RC). Methods: Within the Health Care Utilization Project Nationwide Inpatient Sample (NIS), we focused on patients in whom RC was performed between 1998 and 2007. Multivariable logistic regression analyses were fitted to predict the likelihood of blood transfusions, prolonged length of stay, intraoperative and postoperative complications, and in-hospital mortality. Covariates included age, race, gender, Charlson Comorbidity Index (CCI), hospital region, insurance status, annual hospital caseload (AHC), year of surgery and urinary diversion. Results: Overall, 12 262 patients underwent RC. Of those, 7892 (64.4%) were from academic institutions. Patients treated at academic institutions were younger and healthier at baseline (all p < 0.001). RCs performed at academic institutions were associated with fewer postoperative complications (28.8% vs. 32.9%, p < 0.001), shorter length of stay (54.0% vs. 56.2%, p = 0.02) and lower in-hospital mortality rates (2.1 vs. 3.0%, p = 0.002). In multivariable analyses, patients who underwent RC at an academic hospital were 12% less likely to succumb to postoperative complications (odds ratio=0.88, p = 0.003). Interpretation: Even after adjusting for AHC, RCs performed at academic institutions are associated with better postoperative outcomes than RCs performed at non-academic institutions. From a public health prospective, performing RCs at academic institutions may help reduce costs associated with the management of complications and prolonged length of stay. PMID:23093532

    Nearly 80% of patients with newly diagnosed bladder cancer present with superficial bladder tumors (confined to the bladder lining such as transitional cell carcinoma [90%], squamous cell carcinoma [6-8%], and adenocarcinoma[2%]) in stages Ta, Tis, or T1. Segmental cystectomy is one surgical treatment for patients who have a low-grade invasive tumor. Transposition of small intestine is a viable surgical treatment option. Success of the transplantation is also dependent upon removal of the entire SI mucosal layer. A Clark Spitfire Ti:Sapphire laser operating at 775 nm and 1 kHz repetition rate, was used to investigate the damage induced to fresh cadaveric porcine small intestinal mucosal epithelium. The laser was held constant at a focal spot diameter of 100 μm using a 200 mm focal point lens, with a power output maximum of 257 mW. A high resolution motorized X-Y-Z stage translated the SI tissue through the beam at 500 μm/sec with a line spacing of 50 μm. This produced a 50% overlap in the laser etching for each pass over a 1 cm x 1.5 cm grid. To determine if the mucosal lining of the SI was adequately removed, the targeted area was covered with 1% fluorescein solution for 30 seconds and then rinsed with phosphate buffered saline. Fluorescein staining was examined under UV illumination, to determine the initial degree of mucosal removal. Tissues were fixed and processed for light and scanning electron microscopy by standard protocols. Brightfield light microscopy of hematoxylin and eosin stained 4 μm thick cross sections, scanning electron microscopy were examined to determine the degree of mucosal tissue removal. Clear delineation of the submucosal layer by fluorescein staining was also observed. The Ti:Sapphire laser demonstrated precise, efficient removal of the mucosal epithelium with minimal submucosal damage.

    Introduction: We aimed to assess contemporary rates of neoadjuvant chemotherapy (NC) use. Methods: We relied on the Surveillance, Epidemiology and End Results (SEER)-Medicare database for non-metastatic, muscle-invasive (T2–T4a) urothelial carcinoma of the urinary bladder (UCUB) patients who underwent radical cystectomy (RC) between 1991 and 2009. Multivariable logistic regression analyses tested predictors of NC use, such as: T-stage, N-stage, year of diagnosis, age at diagnosis, gender, race, use of radiotherapy (RT), marital status, urban status, socioeconomic status, tumour grade, and Charlson comorbidity index (CCI). Results: Overall, 5207 patients treated with RC were identified. Of those, 332 (6.4%) received NC. The rate of NC increased over time from 6.1% (1991) to 15.0% (2009) (p<0.001). In multivariable analyses, year of diagnosis (odds ratio [OR]: 4.7; p<0.001), lower T-stage (T3 vs. T2: OR: 0.7; p=0.003), married status (OR: 1.5; p=0.006), and younger age at diagnosis (≥80 vs. 66–69: OR: 0.6; p=0.006) were associated with a higher odds of NC; all represented independent predictors of NC use. Neither race nor CCI demonstrated statistical significance. Conclusions: We reported lower than anticipated overall (6.4%) use of NC. Nonetheless, the rate increased from 6.1% (1991) to 15.0% (2009). Older and unmarried individuals were less likely to receive NC. NC rates were higher in T2 UCUB patients. Some of the observed discrepancies, such as lower use in unmarried individuals, may require correction. Better adherence to guidelines should be encouraged and implemented, especially based on the confirmed benefits of NC according to randomized, controlled trials. The study is limited by a retrospective design and limited variables. PMID:27330584

    Background There is a lack of good data in the literature evaluating the Health-Related Quality of Life (HR- QoL) in patients with urinary diversions. The aim of this study was to examine the changes in expectation and needs in terms of human adaptation and behavioural profiles in patients with ileal conduit (IC) after radical cystectomy (RC) for bladder cancer (BC). Materials and methods A qualitative, multicenter cross-sectional study using a “narrative based” approach was planned. We proceed with a sampling reasoned choice (purposive), selecting groups of patients with follow-up from one up to more than 7 years after surgery. Data were collected through individual interviews. Results Thirty patients participated in the study. The processing of the interviews allowed us to identify 2 major profiles: positive and negative. Patients with a positive profile resumed normal daily activities with no or limited restrictions both on the personal and the social level. This profile reflects a good HR-QoL. The negative profile reflects the patients for whom the ostomy has meant a worsening of HR-QoL. A positive profile was statistically more frequent in older patients (p = 0.023), with a longer follow-up (p = 0.042) and less complications rates (p = 0.0002). According to the length of follow-up and the occurrence of complitations, we identified further 5 intermediate profiles. Conclusions Patients’ satisfaction is related to the degree of adaptation to their new life with an urinary stoma and its correct management. Live “with urinary diversion” represents a new phase of life and not a deterioration. PMID:24708662

    OBJECTIVE To characterize the outcomes and predictors of readmission after robot-assisted radical cystectomy (RARC) during early (30-day) and late (31–90–day) postoperative periods. METHODS We retrospectively evaluated our prospectively maintained RARC quality assurance database of 272 consecutive patients operated between 2005 and 2012. We evaluated the relationship of readmission with perioperative outcomes and examined possible predictors during the postoperative period. RESULTS Overall 30- and 90-day mortality was 0.7% and 4.8%, respectively, with 25.5% patients readmitted within 90 days after RARC (61% of them were readmitted within 30 days and 39% were readmitted between 31–90 days postoperatively). Infection-related problems were the most common cause of readmission during early and late periods. Overall operative time and obesity were significantly associated with readmission (P = .034 and .033, respectively). Body mass index and female gender were independent predictors of 90-day readmission (P = .004 and .014, respectively). Having any type of complication correlated with 90-day readmission (P = .0045); meanwhile, when complications were graded on the basis of Clavien grading system, only grade 1–2 complications statistically correlated with readmission (P = .046). Four patients needed reoperation (2 patients in early “for appendicitis and adhesive small bowel obstruction” and 2 in late “for ureteroenteric stricture” readmission); meanwhile, 6 patients needed percutaneous procedures (4 patients in early “1 for anastomotic leak and 3 for pelvic collections” and 2 “for pelvic collections and ureterocutaneous fistula” in late readmission). CONCLUSION The rate of readmission within 90 days after RARC is significant. Female gender and body mass index are independent predictors of readmission. Outcomes at 90 days provide more thorough results, essential to proper patient counseling. PMID:24468509

    This report is aimed to describe a life-threatening case of anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis secondary to ovarian teratoma with rapid recovery in 1 day after the removal of the tumour. A 23-year-old woman presented with sudden headache, personality changes and seizure. After neurological assessment, limbic or herpes encephalitis was provisionally diagnosed and treated with intravenous immunoglobulin, acyclovir and steroids. The patient had progressive severe neurological symptoms, requiring prolonged intubation and mechanical ventilation. An anti-NMDAR antibody test revealed positive in serum and cerebrospinal fluid at 3 weeks of admission. Pelvic ultrasound examination and CT scan revealed bilateral small ovarian teratomas. Bilateral ovarian cystectomy was performed by open surgery. The patient showed rapid improvement and no longer needed intubation 2 days after the operation. In conclusion, we described a catastrophic case of ovarian teratoma-associated encephalitis with delayed diagnosis but rapid recovery after ovarian cystectomy. This information can probably be helpful to neurologists and gynaecologists. PMID:27511754

    We assessed the associations between preoperative and postoperative serum anti-Müllerian hormone (AMH) levels and parameters of endometriosis and endometriomas surgery with the success of infertility treatments after cystectomy. Seventeen out of 54 patients got pregnant during the infertility treatments. In these patients, the median interval from surgery to conception was 16.3 months. The serum AMH levels 1-year postoperatively were significantly higher in the pregnant group compared to the non-pregnant group (3.44 ± 1.78 versus 2.17 ± 2.24 ng/ml, p = 0.049). The median interval from surgery to recurrence was 34.4 months, and no significant differences were found in the serum AMH levels at any time point between the recurrence and non-recurrence groups. Serum AMH levels 1 year after laparoscopic cystectomy for endometriomas may predict the success of postoperative infertility treatments, but not a recurrence of endometriomas. PMID:26597472

    Secondary perineal herniation of intraperitoneal contents represents a rare complication following procedures such as abdominoperineal rectal resection or cystectomy. We present a case of a perineal hernia formation with prolapse of an ileum neobladder following radical cystectomy and rectal resection for recurrent bladder cancer. Following consecutive resections in the anterior and posterior compartment of the lesser pelvis, the patient developed problems emptying his neobladder. Clinical examination and computed tomography revealed perineal herniation of his neobladder through the pelvic floor. Through a perineal approach, the hernial sac could be repositioned, and via a combination of absorbable and non-absorbable synthetic mesh grafts, the pelvic floor was stabilised. Follow-up review at one year after hernia fixation showed no signs of recurrence and no symptoms. In cases of extensive surgery in the lesser pelvis with associated weakness of the pelvic compartments, meshes should be considered for closure of the pelvic floor. Development of biological meshes with reduced risk of infection might be an interesting treatment option in these cases. PMID:26985818

    A 32-year-old well-nourished man having a vesicosigmoidal fistula due to Crohn's disease received laparoscopic sigmoidectomy with partial cystectomy. The bladder wall was closed with an all-layer running suture and additional interrupted sutures using 2-0 Vicryl. Four months after surgery, the suture site on the bladder showed perforation to the abdominal cavity. Since the same event occurred again 6 months after surgery, open partial cystectomy was performed to repair the perforated site 8 months after the initial surgery. The perforated site showed a thinning bladder wall composed of normal urothelium, scar tissue and thin detrusor muscle. Non-caseating granuloma was not found in the specimen, even though it was slightly observed in the margin of the detrusor muscle resected in the initial surgery. Although it was possible that the persisting activity of Crohn's disease, subclinical impaired nutrition due to Crohn's disease or insufficient suturing of the bladder wall were involved in the bladder rupture, the definitive cause remains unknown.

    Obesity is the major risk factor in cholesterol crystal and gallstone formation. After an Roux-en-Y gastric bypass, biliary duct dilatation can appear and gallstone formation can cause biliary duct obstruction or gallstone pancreatitis. Management of this clinical situation can be challenging and many approaches have been reported. Endoscopic retrograde cholangiopancreatography plays an important role in the management of biliary duct obstruction in these patients. However, a previous modified anatomy makes this procedure technically difficult. For these reason, we describe our single-institution experience in the management of biliary duct obstruction utilizing a hybrid approach combining laparoscopy and flexible endoscopy. PMID:24105293

    Background and Objective More recently laparoscopic radical cystectomy (LRC) has increasingly been an attractive alternative to open radical cystectomy (ORC) and many centers have reported their early experiences in the treatment of bladder cancer. Evaluate the safety and efficacy of LRC compared with ORC in the treatment of bladder cancer. Methods A systematic search of Medline, Scopus, and the Cochrane Library was performed up to Mar 1, 2013. Outcomes of interest assessing the two techniques included demographic and clinical baseline characteristics, perioperative, pathologic and oncological variables, and post-op neobladder function and complications. Results Sixteen eligible trials evaluating LRC vs ORC were identified including seven prospective and nine retrospective studies. Although LRC was associated with longer operative time (p<0.001), patients might benefit from significantly fewer overall complications (p<0.001), less blood loss (p<0.001), shorter length of hospital stay (p<0.001), less need of blood transfusion (p<0.001), less narcotic analgesic requirement (p<0.001), shorter time to ambulation (p = 0.03), shorter time to regular diet (p<0.001), fewer positive surgical margins (p = 0.006), fewer positive lymph node (p = 0.05), lower distant metastasis rate (p = 0.05) and fewer death (p = 0.004). There was no significant difference in other demographic parameters except for a lower ASA score (p = 0.01) in LRC while post-op neobladder function were similar between the two groups. Conclusions Our data suggest that LRC appears to be a safe, feasible and minimally invasive alternative to ORC with reliable perioperative safety, pathologic & oncologic efficacy, comparable post-op neobladder function and fewer complications. Because of the inherent limitations of the included studies, further large sample prospective, multi-centric, long-term follow-up studies and randomized control trials should be undertaken to confirm our findings

    Introduction: This study was aimed at analyzing the need for routine use of frozen section analysis (FSA) before performing orthotopic neobladder (ONB) after radical cystectomy for carcinoma urinary bladder. Materials and Methods: A total of 233 patients underwent radical cystectomy from January 2000 to June 2013. Of these, 151 (65.6%) patients were planned for ONB. In the initial 109 (72%) patients, FSA of urethral margin was performed, but, in the subsequent 42 (28%) patients, frozen section of urethral margin was not sent. Impact of hydroureteronephrosis, tumor size and location of tumor in relation to the bladder neck on the status of the urethral margin was analyzed. Results: Only three of the 109 (2.7%) patients had a positive urethral margin. Two of them had ileal conduit and one, after negative re-resection, had ONB. Although none of the factors was found to be significant, all three patients with a positive urethral margin had growth at the bladder neck and died of cancer at a mean follow up of 29.33 ± 18.3 months, without urethral recurrence. Among the negative FSA (106), two patients had recurrence in the penile urethra. The mean follow-up was 46.3 ± 25.1 months. None of the patients without FSA (42) had urethral recurrence at the mean follow-up of 36 ± 9.3 months. Of the 28 patients who had their growth located at the bladder neck, three had positive FSA, while none with growth away from the bladder neck had positive FSA. Conclusion: Routine FSA of the urethra before performing ONB can be avoided in those patients where the tumor does not reach the bladder neck. PMID:26604448

    Introduction: We investigate the cytocidal effect of water on bladder cancer cells. Intraperitoneal lavage with sterile water is sometimes used during radical cystectomy to lyse cancer cells that might have escaped the surgical specimen. The efficacy of this approach at the cellular level is unknown. Methods: Three bladder cancer cell lines of varying grade, RT4, TCCSUP and T24 were exposed to sterile water, and morphological changes were closely observed under microscopy. Changes of cell membrane integrity, cell viability, and cell number of re-incubated cells after water exposure were measured to determine water induced hypotonic shock. Results: The low-grade RT4 cells started swelling immediately upon exposure to water followed by rupture within 3 minutes. The higher grade TCCSUP and T24 cells demonstrated limited hypotonic swelling with significantly less cell rupture after 10 minutes. The damage to cell membrane of RT4 cells was evident at 1 minute; only 10.0% of cells were intact at 10 minutes. On the other hand, 41.9% and 77.8% of TCCSUP and T24 cells were intact at 10 minutes, respectively. Percentage of viable cells at 10 minutes was 2.1 ± 2.3%, 2.3 ± 0.4%, and 16.1 ± 0.6% for RT4, TCCSUP, and T24, respectively. Conclusions: Cytocidal effect of hypotonic shock can be achieved, to varying degrees, by exposing bladder cancer cells to water for at least 10 minutes. This in vitro study may have bearing on the effects seen with intraperitoneal lavage using sterile water during radical cystectomy. PMID:25844095

    Purpose To describe a novel modification to robot-assisted partial cystectomy (RAPC) that allows for intraoperative surgical margin assessment by bimanual-examination and frozen-section analysis. Materials and Methods A total of 7 patients underwent RAPC at a single tertiary-care institution between 2008 and 2013. The technique evolved over the study-period and permitted real-time intraoperative surgical margin evaluation in the last 5 patients via bimanual-examination and frozen-section analysis, utilizing the GelPOINT platform (a hand-assist device). The GelPOINT platform was placed through a 4- to 5-cm vertical supraumbilical incision and allowed for rapid retrieval of the bladder specimen without compromising the pneumoperitoneum or prolonging the operative time. Perioperative, oncological and functional outcomes were evaluated; all patients had a minimum 12-month follow-up. At the time of last follow-up, a cross-sectional survey of patients was performed to evaluate regret/satisfaction utilizing validated questionnaires. Results The mean age was 72.5 years; 71.4% of the patients were men (n=5). All patients underwent RAPC for a malignant indication. The mean operative and console times were 291 and 217 minutes, respectively. No patient had a positive surgical margin. Mean length-of-stay was 1.7 days. At a median follow-up of 38.9 months, 1 patient experienced a local recurrence 6 months postsurgery. The only mortality was secondary to Lewy-body disease, in the same patient, 1 year postoperatively. Patient assessment of regret and satisfaction indicated 0% regret and 0% dissatisfaction. Conclusions The 'modified' technique of RAPC is technically feasible, safe, and reproducible; further, RAPC leads to favorable oncological, functional and quality-of-life outcomes in patients eligible for partial cystectomy.

    ABSTRACT Purpose: To compare complications and outcomes in patients undergoing either open radical cystectomy (ORC) or robotic-assisted radical cystectomy (RRC). Materials and Methods: We retrospectively identified patients that underwent ORC or RRC between 2003- 2013. We statistically compared preliminary oncologic outcomes of patients for each surgical modality. Results: 92 (43.2%) and 121 (56.8%) patients underwent ORC and RRC, respectively. While operative time was shorter for ORC patients (403 vs. 508 min; p<0.001), surgical blood loss and transfusion rates were significantly lower in RRC patients (p<0.001 and 0.006). Length of stay was not different between groups (p=0.221). There was no difference in the proportion of lymph node-positive patients between groups. However, RRC patients had a greater number of lymph nodes removed during surgery (18 vs. 11.5; p<0.001). There was no significant difference in the incidence of pre-existing comorbidities or in the Clavien distribution of complications between groups. ORC and RRC patients were followed for a median of 1.38 (0.55-2.7) and 1.40 (0.582.59) years, respectively (p=0.850). During this period, a lower proportion (22.3%) of RRC patients experienced disease recurrence vs. ORC patients (34.8%). However, there was no significant difference in time to recurrence between groups. While ORC was associated with a higher all-cause mortality rate (p=0.049), there was no significant difference in disease-free survival time between groups. Conclusions: ORC and RRC patients experience postoperative complications of similar rates and severity. However, RRC may offer indirect benefits via reduced surgical blood loss and need for transfusion. PMID:27564275

    Purpose: We have previously reported on the mortality, morbidity, and 5-year survival of 458 patients who underwent radical radiotherapy or surgery for invasive bladder cancer in Yorkshire from 1993 to 1996. We aim to present the 10-year outcomes of these patients and to reassess factors predicting survival. Methods and Materials: The Northern and Yorkshire Cancer Registry identified 458 patients whose cases were subjected to Kaplan-Meier all-cause survival analyses, and a retrospective casenote analysis was undertaken on 398 (87%) for univariate and multivariate Cox proportional hazards modeling. Additional proportional hazards regression modeling was used to assess the statistical significance of variables on overall survival. Results: The ratio of radiotherapy to cystectomy was 3:1. There was no significant difference in overall 10-year survival between those who underwent radiotherapy (22%) and radical cystectomy (24%). Univariate analyses suggested that female sex, performance status, hydronephrosis and clinical T stage, were associated with an inferior outcome at 10 years. Patient age, tumor grade, treatment delay, and caseload factors were not significant. Multivariate analysis models were created for 0-2 and 2-10 years after treatment. There were no significant differences in treatment for 0-2 years; however, after 2 years follow-up there was some evidence of increased survival for patients receiving surgery compared with radiotherapy (hazard ratio 0.66, 95% confidence interval: 0.44-1.01, p = 0.06). Conclusions: a 10-year minimum follow-up has rarely been reported after radical treatment for invasive bladder cancer. At 10 years, there was no statistical difference in all-cause survival between surgery and radiotherapy treatment modalities.

    Objective The aim of this study was to assess potential benefits of different extended lymph-node dissection templates at the time of radical cystectomy as treatment for invasive bladder cancer. Materials and methods Between 2004 and 2012, 578 patients underwent radical cystectomy with lymph-node dissection without prior radiotherapy or chemotherapy. Two different historical cohorts were constructed: 262 patients underwent intended superextended lymph-node dissection (seLND) from January 2004 to January 2009 and 316 patients underwent intended extended lymph-node dissection (eLND) from February 2009 to December 2012. Recurrence-free survival (RFS) was analysed as the primary outcome. Median follow-up was 93 (63-123) months and 38 (16-63) months in the two groups, respectively. Results There was no significant difference in RFS in the two cohorts (p = 0.87). When analysed according to lymph-node status (N0 or N+), there was no significant difference in RFS between the two cohorts in the two subgroups (p = 0.41 and p = 0.48, respectively). When analysed according to tumour stage, patients with non-organ-confined disease revealed a tendency towards better RFS in the seLND cohort (p = 0.14). This tendency was most clearly seen in the subgroup of T3-4 patients without lymph-node metastases (N0) (p = 0.14). Conclusions Extending LND up to the inferior mesenteric artery (seLND) does not seem to be beneficial to the overall population of patients with invasive bladder cancer compared to performing an eLND to the aortic bifurcation only. However, a subgroup of patients with non-organ-confined disease without macrometastases may benefit from seLND. PMID:27049808

    Most surgical patients end up with a scar and most of these would want at least some improvement in the appearance of the scar. Using sound techniques for wound closure surgeons can, to a certain extent, prevent suboptimal scars. This article reviews the principles of prevention and treatment of suboptimal scars. Surgical techniques of scar revision, i.e., Z plasty, W plasty, and geometrical broken line closure are described. Post-operative care and other adjuvant therapies of scars are described. A short description of dermabrasion and lasers for management of scars is given. It is hoped that this review helps the surgeon to formulate a comprehensive plan for management of scars of these patients. PMID:24516292

    Parastomal hernias (PH) represent a clinically significant problem for many patients after radical cystectomy and ileal conduit diversion. The prevalence may be as high as 60% and in some series, up to 30% of patients require surgical intervention due to the complications of pain, poor fit of an ostomy appliance, leakage, urinary obstruction, and bowel obstruction or strangulation. Due to the potential morbidity associated with PH repair, there have been efforts to prevent PH development at the time of the index surgery. Four randomized trials of prophylactic mesh placement at the time of colostomy and ileostomy stoma formation have demonstrated significant reductions in PH rates with acceptably low complication rates. In this review, we describe the clinical and radiographic definitions of PH, the clinical impact and risk factors behind its development, and the rationale behind prophylactic mesh placement for patients undergoing ileal conduit urinary diversion. Additionally, we report our experience with prophylactic mesh placed at radical cystectomy at our institution. PMID:26757903

    Introduction: It is uncertain whether there are disparities related to receiving long-term radiographic follow-up after cystectomy performed for bladder cancer, and whether intensive follow-up influences survival. Materials and Methods: We analyzed 2080 patients treated with cystectomy between 1992 and 2004 isolated from the SEER-Medicare database. The number of abdominal computerized tomography scans performed in patients surviving 2 years after surgery was used as an indicator of long-term radiographic follow-up to exclude patients with early failures. Results: Patients were mainly males (83.18%), had a mean age at diagnosis of 73.4 ± 6.6 (standard deviation) years, and mean survival of 4.6 ± 3.2 years. Multivariate analysis showed age >70 (odds ratio [OR]: 0.796, 95% confidence interval [CI]: 0.651–0.974), African American race (OR: 0.180, 95% CI: 0.081–0.279), and Charlson comorbidity score >2 (OR: 0.694, 95% CI: 0.505–0.954) to be associated with lower odds of long-term radiographic follow-up. Higher disease stage (Stage T4N1) (OR: 1.873, 95% CI: 1.491–2.353), higher quartile for education (OR: 5.203, 95% CI: 1.072–9.350) and higher quartile for income (OR: 6.940, 95% CI: 1.444–12.436) were associated with increased odds of long-term radiographic follow-up. Interestingly, more follow-up with imaging after cystectomy did not improve cancer-specific or overall survival in these patients. Conclusion: There are significant age, race, and socioeconomic disparities in long-term radiographic follow-up after radical cystectomy. However, more radiographic follow-up may not be associated with better survival. PMID:27141188

    In 1981, a series of 236 intranasal ethmoidectomy (INE) procedures was reported with a complication rate of 1.8%. Special attention has subsequently been directed to the surgical failures; namely, recurrent nasal polyposis which accounted for approximately 17%. The reason for recurrence in most instances was felt due to failure to do a more thorough posterior ethmoidectomy and enter and clean out the sphenoid sinuses. Subsequently, in all revision cases where a more thorough sphenoidethmoidectomy (RSE) was performed, the overall long-term success rate raised to better than 90%. Attention to skeletonizing the middle turbinate by stripping mucosa and leaving a thin bony shell is an important technical factor. An attempt is made to leave some of this bony skeletonized medial wall of the middle turbinate as it represents the most crucial landmark in doing the surgery via the intranasal route. There still remains approximately 8% to 10% of this patient population with nasal polyposis and sinusitis of such severity that surgery has offered only a temporary measure of relief. In dealing with this group it may be necessary to see these patients postoperatively at four to six-week intervals, carefully suctioning the ethmoid labyrinth and occasionally doing minor office "touch-up" ethmoidectomy-polypectomy procedures to clean off redundant mucosa or early polyposis. This paper is written to offer a compromise to the two schools of intranasal ethmoidectomy surgery as to the necessity of removing the middle turbinate in its entirety. PMID:3974381

    High grade neuroendocrine carcinomas (HGNEC) treated by cystectomy often carry an original diagnosis of typical urothelial carcinoma (UC). The correct diagnosis of HGNEC is critical in influencing the decision for early chemotherapy, potentially followed by cystectomy. The objective of this study was to characterise the features of HGNEC treated by radical cystectomy. The study consisted of 79 patients with HGNEC including small cell (68 patients), large cell neuroendocrine (LCNEC) (5 patients) and mixed neuroendocrine (mixed-NEC) carcinoma (6 patients) matched with 122 patients with UC, treated at our institution between 1987 and 2014. Morphometric analysis for cell and nuclear size as well as immunophenotyping for neuroendocrine markers and cell-cycle regulators were applied to tissue microarrays. Small cell, LCNEC and mixed-NEC are a morphological spectrum of high grade neuroendocrine carcinoma with overlapping histological features, identical immunophenotype, Ki-67 proliferative rate and patient outcomes. Finally, the nuclear size criteria is misleading as HGNEC, particularly cases of LCNEC and mixed-NEC, may have enlarged nuclei compared to small cell carcinomas and are more prone to be misdiagnosed as UC, thereby preventing appropriate management.

    Background: Laparoscopic radical cystectomy (LRC) is increasingly being used for muscle-invasive bladder cancer. However, high levels of clinical evidence comparing laparoscopic vs open radical cystectomy (ORC) are lacking. Methods: A prospective randomised controlled clinical trial comparing LRC vs ORC in patients undergoing radical cystectomy for bladder cancer. Thirty-five patients were eligible for final analysis in each group. Results: The median follow-up was 26 months (range, 4–59 months) for laparoscopic vs 32 months (range, 6–60 months) for ORC. Significant differences were noted in operative time, estimated blood loss (EBL), blood transfusion rate, analgesic requirement, and time to resumption of oral intake. No significant differences were noted in the length of hospital stay, complication rate, lymph node yield (14.1±6.3 for LRC and 15.2±5.9 for ORC), positive surgical margin rate, postoperative pathology, or recurrence rate (7 for LRC and 8 for ORC). The 5-year recurrence-free survival with laparoscopic vs ORC was 78.5% vs 70.9%, respectively (P=0.773). The overall survival with laparoscopic vs ORC was 73.8% vs 67.4%, respectively (P=0.511). Conclusion: Our study demonstrated that LRC is superior to ORC in perioperative outcomes, including EBL, blood transfusion rate, and analgesic requirement. We found no major difference in oncologic outcomes. The number of patients is too small to allow for a final conclusion. PMID:24407192

    The pathological analysis of cystectomy specimens from 360 female patients who underwent radical cystectomy for bladder cancer was retrospectively reported. The uterus was not available in 29 specimens, while one ovary was absent in 18 specimens and the two ovaries were absent in 20 specimens. Uterine involvement was observed in one case of transitional cell carcinoma, and benign uterine pathology was detected in 37 cases. All patients had normal ovaries, while the vagina was involved in 13 cases. A total of 12% of the patients had urethral involvement. None of the 29 patients, in whom the internal genitalia were totally or partially preserved, had late ovarian, vaginal or uterine recurrence at the last follow-up. Thus, the preservation of female internal genitalia in young patients undergoing radical cystectomy should be considered under strict criteria (low-grade, low-stage tumours away from the bladder neck). This will improve the quality-of-life (QoL) and the functional outcome without compromising cancer control. PMID:22779969

    Background. Surgical treatment of hydatid liver disease (HLD) is divided into conservative and radical procedures. While conservative techniques are easier and faster to perform, there is an emerging need to reduce their morbidity and recurrence rates. Our aim was to present and evaluate the efficiency and safety of the application of radiofrequency energy (TissueLink® and Aquamantys® systems) in hepatic bed during partial cystectomy. Materials and Methods. Eighteen consecutive patients with hydatid liver cysts were referred to our department between April 2006 and June 2014. Data about demographics, mortality, morbidity, and recurrence rate were obtained and analyzed retrospectively. Results. The mean follow-up was 38 months (range: 4–84 months). The postoperative course of most patients was uneventful. One case of recurrence was found in our series in a patient with 4 cysts in the right lobe, 3 years after initial treatment. He was reoperated on with the same method. Conclusions. Saline-linked RF energy seems to be an effective means to be employed in conservative surgical procedures of HLD, with satisfactory postoperative morbidity. Recurrence rates appear to be low, but further follow-up is needed in order to draw safer conclusions. PMID:27525000

    We aimed to investigate the incidence and long-term outcome of moyamoya syndrome in pediatric patients with primary brain tumors after receiving cranial radiotherapy (RT) in a single institute in Taiwan. The complete medical records, medical images, and RT notes of 391 pediatric patients with primary brain tumors treated with cranial RT between January 1975 and December 2005 in Taipei Veterans General Hospital (TVGH), Taiwan, were entered into an electronic registry and reviewed. Eight (2%) cases of post-RT moyamoya syndrome were identified in the sample of 391 patients. The median latency was 3 years post-RT. Among the eight patients, three had craniopharyngioma, two had optic glioma, two had medulloblastoma, and one had a suprasellar astrocytoma. The prescribed physical doses of RT were in the range of 40-54 Gy. The incidence was highest in those with optic glioma (0.039/person-year), followed by craniopharyngioma (0.013/person-year), astrocytoma (0.003/person-year), and medulloblastoma (0.002/person-year). No patients died of vasculopathy. No difference in crude incidence was found between our results and those of other series. The incidence of moyamoya syndrome was diagnosis dependent, with the highest incidence among patients with optic glioma. No regional difference in incidence was found. Long-term, stable neurological function may be achieved following timely surgical intervention. PMID:27265024

    The accurate identification of glioblastoma progression remains an unmet clinical need. The aim of this prospective single-institutional study is to determine and validate thresholds for the main metabolite concentrations obtained by MR spectroscopy (MRS) and the values of the apparent diffusion coefficient (ADC) to enable distinguishing tumor recurrence from pseudoprogression. Thirty-nine patients after the standard treatment of a glioblastoma underwent advanced imaging by MRS and ADC at the time of suspected recurrence - median time to progression was 6.7 months. The highest significant sensitivity and specificity to call the glioblastoma recurrence was observed for the total choline (tCho) to total N-acetylaspartate (tNAA) concentration ratio with the threshold ≥ 1.3 (sensitivity 100.0% and specificity 94.7%). The ADCmean value higher than 1313 × 10(- 6) mm(2)/s was associated with the pseudoprogression (sensitivity 98.3%, specificity 100.0%). The combination of MRS focused on the tCho/tNAA concentration ratio and the ADCmean value represents imaging methods applicable to early non-invasive differentiation between a glioblastoma recurrence and a pseudoprogression. However, the institutional definition and validation of thresholds for differential diagnostics is needed for the elimination of setup errors before implementation of these multimodal imaging techniques into clinical practice, as well as into clinical trials.

    Context: To analyze the results of episcleral plaque brachytherapy using indigenous Bhabha Atomic Research Centre (BARC) Iodine-125 Ocu-Prosta seeds for the management of intraocular tumors from a single institute. AIM: To report our initial experience and learning curve on the use of ‘BARC I-125 Ocu-Prosta seeds’ for the management of intraocular tumors such as choroidal melanomas, retinoblastomas and vasoproliferative tumors (VPT). Materials and Methods: We retrospectively reviewed 13 eyes of 13 patients who underwent ophthalmic brachytherapy between May 2008 to March 2012. Nine cases had choroidal melanomas; three had retinoblastomas while one case had VPT. Results: For choroidal melanomas the average apical diameter before brachytherapy was 7.6 mm and average largest basal diameter was 12.1 mm, respectively, which reduced to 4.2 mm and 7.7 mm after the procedure at an average follow-up of 24 months (range 10-43 months). Retinoblastoma and VPT also showed good regression after brachytherapy. Conclusion: Plaque radiotherapy using 125I seeds can be performed under peribulbar anesthesia and provides a viable option for the management of intraocular cancer with minimal invasiveness and surgical complications. Patients in our studies experienced excellent local tumor control. With the availability of indigenous ‘BARC I-125 Ocu-Prosta seeds’ locally, cost effective ophthalmic brachytherapy can be performed in India. PMID:22824598

    Purpose: To evaluate the importance of surgical margins for local and systemic control of Ewing's sarcoma family tumors (ESFT). Methods and Materials: Between 1979 and 1999, 512 patients with ESFTs entered 4 different adjuvant and neoadjuvant studies performed at a single institution. Of these patients, 335 were treated with surgery alone (196) or surgery followed by radiotherapy at doses of 44.8 Gy (139). We compared their outcome with that of the 177 patients who were locally treated by radiotherapy at 60 Gy. Results: Local control (88.8% vs. 80.2%, p < 0.009) and 5-year disease-free survival (63.8% vs. 47.6%, p < 0.0007) were significantly better in patients treated with surgery and, among them, in those with adequate surgical margins (96.6% vs. 71,7%, p < 0.0008, and 69.6% vs. 46.3%, p < 0.0002). Nonetheless, better results were observed only in extremity tumors. Conclusions: Surgery is better than radiotherapy in cases of extremity ESFT with achievable adequate surgical margins, and in cases of inadequate surgical margins, adjuvant reduced-dose radiotherapy is ineffective. Therefore, when inadequate margins are expected, patients are better treated with full-dose radiotherapy from the start.

    Background: It is estimated that 74,000 men and women in the United States will be diagnosed with bladder cancer and 16,000 will die from the disease in 2015. The incidence of bladder cancer in Caucasian males is double that of African American males, but African American men and women have worse survival. Although factors contributing to this disparity have been analyzed, there is still great uncertainty as to why this disparity exists. Objective: To evaluate whether the disparities in bladder cancer survival after radical cystectomy for transitional cell carcinoma (TCC) of the bladder amongst African American (AA) and Caucasian patients is attributable to patient demographics, year of diagnosis, and/or tumor characteristics. Methods: Using Surveillance, Epidemiology, and End Results Program (SEER) data from 1973–2011, African American and Caucasian patients treated with a radical cystectomy for TCC of the bladder were identified. Primary outcomes were all-cause and cancer-specific mortality. Differences in survival between African Americans and Caucasian patients were assessed using chi-square tests for categorical variables and Student’s t-tests for continuous variables. Cox proportional hazards regression was used to measure the hazard ratio for African Americans compared to Caucasians for all-cause and cancer-specific mortality. In addition, coarsened matching techniques within narrow ranges, were used to match African American and Caucasian patients on the basis of age, sex, and cancer stage. Following matching, differences in all-cause and cancer-specific mortality were again assessed using a stratified Cox proportional hazards model, using the matching strata for the regression strata. Results: The study cohort consisted of 21,406 African American and Caucasian patients treated with radical cystectomy for bladder urothelial cancer, with 6.2% being African American and 73.9% male. African American patients had worse all-cause and cancer

    The aim of the present study was to retrospectively evaluate the contribution and effectiveness of 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT) scans in the restaging of patients following radical cystectomy due to muscle-invasive bladder carcinoma (MIBC). A total of 51 patients (45 males and six females) who underwent radical cystectomy due to invasive bladder cancer, and had an 18F-FDG-PET/CT scan for restaging between July 2007 and April 2013, were included in the present study. The mean age was 62.3±9.79 years (range, 40–82 years). Patients underwent a six-hour fast prior to scanning, and whole-body PET scanning from the skull base to the upper thighs was performed ~1 h after the intravenous injection of 555 MBq 18F-FDG. Whole-body CT scanning was performed in a cranio-caudal direction. 18F-FDG-PET images were reconstructed using CT data for attenuation correction. Histopathology or clinical follow-up was used to confirm any suspicious recurrent or metastatic lesions. The results for sensitivity, specificity, positive predictive value (PPV), negative predictive value and accuracy of 18F-FDG-PET/CT were 92, 83, 94, 77 and 90%, respectively. In conclusion, 18F-FDG-PET/CT efficiently detects local recurrence and distant metastases with high sensitivity and PPV in the restaging of patients who underwent radical cystectomy due to invasive bladder cancer. This procedure could play an important role in rendering decisions regarding radiotherapy or chemotherapy and post-operative follow-up, and could influence the entire decision-making process.

    Radical cystectomy, as the most common surgical treatment for patients with invasive bladder cancer (IBC) complicated by peritoneal metastasis, is usually accompanied by a urinary diversion procedure. In this study, we evaluated the improved tubeless cutaneous ureterostomy technique by comparing the resulting clinical effects with either a traditional ureterostomy and an ileal conduit urinary diversion. Clinical data from 85 patients who underwent 1 of the 3 procedures between April 2012 and April 2015 were analyzed retrospectively. In total, 30 patients underwent improved tubeless cutaneous ureterostomy, 28 patients underwent a traditional cutaneous ureterostomy and 27 underwent an ileal conduit urinary diversion following radical cystectomy. The incidence of complications, including stoma infection, nipple atrophy, terminal necrosis, urine leakage, external orifice stenosis, uronephrosis and ureterectasia in the group of patients treated with the improved tubeless ureterostomy technique was significantly lower than that of the patients in the other 2 groups, and the difference was statistically significant (P<0.05). In addition, the duration of the surgery, intra-operative bleeding, the duration of the hospitalization period and the time to extubation in the patients treated with the improved tubeless ureterostomy technique were significantly decreased (P<0.05) compared with the patients in the other 2 groups. Finally, the health-related quality of life of the patients treated with the improved tubeless ureterostomy technique was significantly higher (P<0.05) than that of the patients in the other 2 groups. The findings of our study demonstrated that the use of the improved tubeless cutaneous ureterostomy technique following radical cystectomy in patients with IBC complicated by peritoneal metastasis resulted in improved clinical effects. Thus, improved tubeless cutaneous ureterostomy may be a promising alternative for enhancing the quality of life of patients

    Objectives Radical cystectomy (RC) is associated with significant blood loss and transfusion requirement. We performed a prospective, randomized trial to compare blood loss, operative time, and cost using 2 different and commonly employed approaches to tissue ligation and division during RC: mechanical (stapler device) and electrosurgical (heat-sealing device). Methods and materials Eighty patients undergoing RC for urothelial bladder carcinoma were randomized to use of either an Endo GIA Stapler or Impact LigaSure device for tissue ligation and division. Primary outcomes were blood loss, operative time, and device costs. Data were analyzed with Wilcoxon rank sum test and Welch 2-sample t test. Results There were no significant demographic or preoperative differences between the cohorts. Mean estimated blood loss was similar between the electrosurgical (687 ml) and stapler (708 ml) arms (P = 0.850). There were no significant differences between cohorts when comparing operative times or transfusion requirement. There was a significant increase in the mean number of adjunctive suture ligatures used in the stapling device arm (3.0 vs. 1.5, P = 0.047). Total device costs were significantly lower with the LigaSure compared with the GIA Stapler ($625.00 vs. $1490.10, P < 0.001). There were no complications attributable to either device. Conclusions This prospective, randomized study demonstrates no significant difference in blood loss, transfusion requirement, or safety between mechanical vs. electrosurgical control of the vascular pedicles. The LigaSure device, however, is significantly less costly than the GIA Stapler and required fewer additional measures for hemostasis. PMID:24054870

    Purpose: To examine the accuracy of clinical staging and its effects on outcome in bladder cancer (BC) patients treated with radical cystectomy (RC), using a large national database. Methods and Materials: A total of 16,953 patients with BC without distant metastases treated with RC from 1998 to 2009 were analyzed. Factors associated with clinical–pathologic stage discrepancy were assessed by multivariate generalized estimating equation models. Survival analysis was conducted for patients treated between 1998 and 2004 (n=7270) using the Kaplan-Meier method and Cox proportional hazards models. Results: At RC 41.9% of patients were upstaged, whereas 5.9% were downstaged. Upstaging was more common in females, the elderly, and in patients who underwent a more extensive lymphadenectomy. Downstaging was less common in patients treated at community centers, in the elderly, and in Hispanics. Receipt of preoperative chemotherapy was highly associated with downstaging. Five-year overall survival rates for patients with clinical stages 0, I, II, III, and IV were 67.2%, 62.9%, 50.4%, 36.9%, and 27.2%, respectively, whereas those for the same pathologic stages were 70.8%, 75.8%, 63.7%, 41.5%, and 24.7%, respectively. On multivariate analysis, upstaging was associated with increased 5-year mortality (hazard ratio [HR] 1.80, P<.001), but downstaging was not associated with survival (HR 0.88, P=.160). In contrast, more extensive lymphadenectomy was associated with decreased 5-year mortality (HR 0.76 for ≥10 lymph nodes examined, P<.001), as was treatment at an National Cancer Institute–designated cancer center (HR 0.90, P=.042). Conclusions: Clinical–pathologic stage discrepancy in BC patients is remarkably common across the United States. These findings should be considered when selecting patients for preoperative or nonoperative management strategies and when comparing the outcomes of bladder sparing approaches to RC.

  4. Immunomodulatory effects of total intravenous and balanced inhalation anesthesia in patients with bladder cancer undergoing elective radical Cystectomy: preliminary results

    PubMed Central

    2013-01-01

    Background Although surgery and anesthesia induce immunesuppression, remains largely unknown whether various anesthetic techniques have different immunosuppressive effects on cancer patients. Therefore, the aim of this study was to investigate the influence of total intravenous anesthesia with target-controlled infusion (TIVA-TCI) and balanced inhalation anesthesia (BAL) on the peri-operative levels of inflammatory cytokines and regulatory T cells (Tregs) in patients with bladder cancer undergoing surgery. Methods Twenty eight consecutive patients with bladder cancer who underwent radical cystectomy were prospectively randomized into two groups to receive TIVA-TCI (n = 14) or BAL (n = 14). Before the induction of anesthesia (T0), 6–8 hours (T1) post-surgery, and 5 days post-surgery (T2), Tregs and serum levels of interleukin -1beta (IL-1β), interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), interleukin −2 (IL-2), interleukin −6 (IL-6), and interleukin −10 (IL-10) were measured. Results In the peri-operative period all cancer patients showed a marked and significant increase in IL-6. Moreover, TIVA-TCI patients also showed a higher increase in IFN-γ, whereas in BAL patients Tregs were reduced by approximately 30% during surgery. The incidence of infections, metastases, and death was similar in both groups. Conclusions The increase in the Th1 response in the TIVA-TCI group and the reduction in Tregs in the BAL group seem to balance the immunosuppressive effect induced by IL-6. Therefore TIVA-TCI and BAL can be both used in major surgery in patients with bladder cancer without worsening the outcome. PMID:23374147

    Background Interval appendectomy (IA) is a controversial subject, with little consensus on its use in patients undergoing treatment for malignancy. We sought to determine the frequency of recurrent appendicitis in cancer patients managed non-operatively (NOM) during index hospitalization for acute appendicitis (AA). Methods Clinical presentation,cancer treatment,follow-up were collected from electronic medical records of patients with CT scan-confirmed AA treated at a single institution between 7/1999 and 7/2009. Results Seventy-two of 109 AA patients underwent appendectomy during index hospitalization (IHA); 34 of these 109 were NOM during index hospitalization. Median index length of NOM patients’ stay was 6 days (0–55), median age 59 (18–80). Indications for NOM were presence of abscess or phlegmon (14), mild symptoms (13), high surgical risk (3), end-stage cancer (3), patient declining surgery (1). Eight NOM patients underwent percutaneous drainage of abdominal abscess (median total duration of IV + oral antibiotics = 12 days (0–55)). There were 6 deaths (1 IHA, 5 NOM): 4 sepsis, 2 cancer progression. At median 19-month follow-up (range 1–103), 4 NOM patients surviving index hospitalization had recurrent AA (11.7%) at 2 (n=2) and 3 months (n=2) after first episode. Overall, 6 had IA (17.6%) 1–7 months post-AA; 25 remained asymptomatic, without IA. Conclusion Among patients at a cancer center managed non-operatively at index hospitalization for AA, recurrent AA was early (<4 months) but uncommon. IA should be offered to those with recurrent symptoms, but appears to have a very limited role after several months of asymptomatic follow-up. PMID:25975342

    The message that health care providers caring for patients with breast cancer would like to put forth, is that, not only early detection is crucial but early treatment too is important in ensuring survival. This paper examines the pattern of presentation at a single institution over a 10-year period from 1995 to 2005. In Malaysia, education outreach programmes are ongoing, with contributions not only from the public sector, but also private enterprise. Articles on breast cancer in local newspapers and women magazines and television are quite commonplace. However are our women getting the right message? Now is an appropriate time to bring the stakeholders together to formulate a way to reach all women in Malaysia, not excluding the fact that we are from different races, different education levels and backgrounds requiring differing ways of delivering health promotion messages. To answer the question of why women present late, we prospectively studied 25 women who presented with locally advanced disease. A quantitative, quasi-qualitative study was embarked upon, as a prelude to a more detailed study. Reasons for presenting late were recorded. We also looked at the pattern of presentation of breast lumps in women to our breast clinic in UMMC and in the surgical clinic in Hospital Kota Bharu, in the smaller capital of the state of Kelantan, in 2003. There is hope for the future, the government being a socially responsible one is currently making efforts towards mammographic screening in Malaysia. However understanding of the disease, acceptance of medical treatment and providing resources is imperative to ensure that health behaviour exhibited by our women is not self-destructive but self-preserving. Women are an integral part of not only the nation's workforce but the lifeline of the family - hopefully in the next decade we will see great improvement in the survival of Malaysian women with breast cancer.

    We investigated the outcomes of treatment for patients with localized prostate cancer (PCa) treated with 3D conformal radiation therapy (3D-CRT) followed by two-fraction high-dose-rate brachytherapy within a single day (2-fr.-HDR-BT/day) at a single institution. A total of 156 consecutive Asian males (median age, 67 years) were enrolled. To compare our findings with those of other studies, we analyzed our results using the D'Amico classification, assigning the patients to low- (n =5; 3.2%), intermediate- (n =36; 23.1%) and high-risk (n =115; 73.7%) groups (Stage T3 PCa patients were classified as high-risk). One patient in the D'Amico low-risk group (20%), 13 intermediate-risk patients (36.1%) and 99 high-risk patients (86.1%) underwent androgen deprivation therapy. We administered a prescription dose of 39 Gy in 13 fractions of 3D-CRT combined with 18 Gy of HDR-BT in two 9-Gy fractions delivered within a single day. We did not distinguish between risk groups in determining the prescription dose. The median follow-up period was 38 months. Of the 156 patients, one died from primary disease and five died from other diseases. The 3-year overall survival (OS) rates were 100%, 100% and 93.7%, and the 3-year ‘biochemical no evidence of disease (bNED)’ rates were 100%, 100% and 96.9% for the D'Amico low-, intermediate- and high-risk groups, respectively. No patient developed ≥ Grade 3 early toxicity. The Grade 3 late genitourinary toxicity rate was 2.6%, and no ≥ Grade 3 late gastrointestinal toxicity occurred. The efficacy and safety of this study were satisfactory, and longer-term follow-up is necessary. PMID:26983988

    In the last few years, conditions for setting up a human biobank in France have been upgraded by taking into account (1) the new laws and regulations that integrate the ethical and societal dimension of biobanking and delineate the risks for patients associated with the procurement of human cells and tissues, (2) the increasing request by scientists for human samples with proven biological quality and sophisticated sets of annotations, including information produced through the evergrowing use of molecular biology in pathology, and (3) establishment of procedures concerning the safety of the personnel working with biological products. For this purpose, health authorities and national research institutes in France have provided significant support for the set up of biobanks. The present work was conducted to describe how we set up a biobank targeting diseases of a specific organ (thyroid gland), with the aim of rapidly developing translational research projects. The prospective experience of a single institution (Pasteur Hospital, Nice, France) over a 6-year period (2004-2009) is presented from the practical point of view of a surgical pathology laboratory. We describe different procedures required to obtain high-quality thyroid biological resources and clinical annotations. The procedures were established for the management of biological products obtained from 1454 patients who underwent thyroid surgery. The preanalytical steps leading to the storage of frozen specimens were carried out in parallel with diagnostic procedures. As the number of international networks for research programs using biological products is steadily increasing, it is crucial to harmonize the procedures used by biobanks. In this regard, the described thyroid biobank has been set up using criteria established by the French National Cancer Institute (Institut National du Cancer) to guarantee the quality of different collections stored in biobanks.

    Pancreatic adenocarcinoma is the fourth leading cause of cancer death. Recently, MM-398 (nanoliposomal irinotecan) was shown to be associated with significant improvement in outcome measures with acceptable toxicities when combined with 5-fluorouracil (5-FU)/leucovorin (LV) compared to 5-FU/LV alone in patients failing one line of gemcitabine-based therapy. There is a paucity of data evaluating the role of irinotecan in combination with 5FU in advanced pancreas cancer (APC). We performed a retrospective analysis of all patients who received mFOLFIRI (minus bolus 5FU and LV). All patients with metastatic disease who had failed at least one line of gemcitabine-based therapy prior to receiving mFOLFIRI were included in this study. Descriptive statistics were used to assess the continuous variables and adverse events (AEs), and Kaplan–Meier methods were used to calculate the median progression-free survival (PFS) and overall survival (OS). Forty patients were included in this analysis. Patients received 1–5 lines of prior therapy (25 % with more than 3 lines of prior therapy). The mean age at diagnosis was 60, and 98 % had ECOG of 1. The mean CA 19-9 at the start of therapy was 33,169 U/ml. The median PFS was 2.59 months [95 % confidence interval (CI) (1.90, 3.54)], and OS was 4.75 months [95 % CI (3.14, 8.98)]. The most common AEs included fatigue (98 %), neuropathy (83 %), anorexia (68 %), nausea (60 %) and constipation (55 %). Grade 3 toxicities included fatigue (13 %) and rash (3 %). There were no observed grade 4 toxicities. In this single-institution retrospective analysis, mFOLFIRI was found to be both tolerable and relatively effective in a heavily pretreated patient population with APC. Future prospective studies should consider evaluating the role of mFOLFIRI in refractory APC. PMID:26995224

    Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs), including polycythemia vera (PV), essential thrombocytosis (ET) and primary myelofibrosis (PMF), are clonal hematopoietic diseases. A single-institution retrospective analysis was performed, including 71 MPN patients diagnosed at the Hakodate Municipal Hospital between April, 2001 and April, 2014, and certain clinical characteristics were identified as effective prognostic factors. The patients were categorized by risk factor scoring based on age, number of abnormal blood cell lineages and splenomegaly at diagnosis, and the association between this categorization and prognosis was analyzed using a statistical procedure. The effect of Janus kinase 2 (JAK2) V617F mutation on prognosis was also investigated. The MPN patients were consolidated into three risk groups based on the margin of intergroup survival differences: i) Score 1–2 (n=23), ii) score 3 (n=24) and iii) score 4–5 (n=24). MPN patients with scores of 4 or 5 exhibited poorer overall survival (OS) compared with those with lower scores (P<0.001). In addition, there were significant differences in event-free survival (EFS) among scoring groups (P=0.0059). PV and ET had a better prognosis compared with PMF, although this analysis suggested that PV and ET patients with scores of 4 or 5 may have a poorer prognosis in terms of OS (P=0.0052) and EFS (P=0.022) and should be closely followed up. We observed no significant prognostic effect of the JAK2V167F mutation for OS (P=0.28) or EFS (P=0.17). Our results suggested that a simple scoring system based on age, blood cell counts and presence of splenomegaly at diagnosis may be used for the long-term prognosis of MPN patients. PMID:26870357

    Background Although primary treatment of localized prostate cancer provides excellent oncologic control, some men who chose radiotherapy experience a recurrence of disease. There is no consensus on the most appropriate management of these patients after radiotherapy failure. In this single-institution review, we compare our oncologic outcome and toxicity between salvage prostatectomy and cryotherapy treatments. Methods From January 2004 to June 2013, a total of 23 salvage procedures were performed. Six of those patients underwent salvage prostatectomy while 17 underwent salvage cryotherapy by two high-volume fellowship-trained urologists. Patients being considered for salvage therapy had localized disease at presentation, a prostate-specific antigen (PSA) < 10 ng/mL at recurrence, life expectancy > 10 years at recurrence, and a negative metastatic workup. Patients were followed to observe cancer progression and toxicity of treatment. Results Patients who underwent salvage cryotherapy were statistically older with a higher incidence of hypertension than our salvage prostatectomy cohort. With a mean follow up of 14.1 months and 7.2 months, the incidence of disease progression was 23.5% and 16.7% after salvage cryotherapy and prostatectomy, respectively. The overall complication rate was also 23.5% versus 16.7%, with the most frequent complication after salvage cryotherapy being urethral stricture and after salvage prostatectomy being severe urinary incontinence. There were no rectal injuries with salvage prostatectomy and one rectourethral fistula in the cohort after salvage cryotherapy. Conclusion While recurrences from primary radiotherapy for prostate cancer do occur, there is no consensus on its management. In our experience, salvage procedures were generally safe and effective. Both salvage cryotherapy and salvage prostatectomy allow for adequate cancer control with minimal toxicity. PMID:27014657

    We aimed to analyze the clinical characteristics and compare the surgical outcome of pancreatic neuroendocrine tumors (p-NETs) using the 2 tumor-node-metastasis (TNM) systems by both the American Joint Committee on Cancer (AJCC) Staging Manual (seventh edition) and the European Neuroendocrine Tumor Society (ENETS). Moreover, we sought to validate the prognostic value of the new AJCC criterion. Data of 145 consecutive patients who were all surgically treated and histologically diagnosed as p-NETs from January 2002 to June 2013 in our single institution were retrospectively collected and analyzed. The 5-year overall survival (OS) rates for AJCC classifications of stages I, II, III, and IV were 79.5%, 63.1%, 15.0%, and NA, respectively, (P < 0.005). As for the ENETS system, the OS rates at 5 years for stages I, II, III, and IV were 75.5%, 72.7%, 29.0%, and NA, respectively, (P < 0.005). Both criteria present no statistically notable difference between stage I and stage II (P > 0.05) but between stage I and stages III and IV (P < 0.05), as well as those between stage II and stages III and IV (P < 0.05). Difference between stage III and IV by ENETS was significant (P = 0.031), whereas that by the AJCC was not (P = 0.144). What's more, the AJCC Staging Manual (seventh edition) was statistically significant in both uni- and multivariate analyses by Cox regression (P < 0.005 and P = 0.025, respectively). Our study indicated that the ENETS TNM staging system might be superior to the AJCC Staging Manual (seventh edition) for the clinical practice of p-NETs. Together with tumor grade and radical resection, the new AJCC system was also validated to be an independent predictor for p-NETs. PMID:25816036

    Background Hyperthermic isolated limb perfusion (HILP) and isolated limb infusion (ILI) are utilized to manage advanced extremity melanoma but no consensus exists as to which treatment is preferable and how to monitor patients post-treatment. Study Design Using a prospectively-maintained database, we reviewed our experience with melphalan based HILP (that included 62 first time and 10 second time) and ILI (that included 126 first time and 18 second time) procedures performed in 188 patients. PET/CT was obtained 3 months post regional treatment for one year and then every 6 months thereafter. Results The overall response rate (complete response (CR) + partial response (PR)) of HILP was 81% (80% CI: 73-87%) while the overall response rate from ILI was 43% (80% CI: 37-49%) for first time procedures only. HILP had a CR rate of 55% with a median duration of 32 months, while ILI had a CR rate of 30% with median duration of 24 months. Patients who experienced a regional recurrence after initial regional treatment were more likely to achieve a CR following repeat HILP (50%, n = 10) compared to repeat ILI (28%, n = 18). Although the spectrum of toxicity was similar for ILI and HILP, the likelihood of rare catastrophic complication of limb loss was greater with HILP (2/62) than ILI (0/122). PET/CT was effective for surveillance after regional therapy to identify regional nodal and pulmonary disease that was not clinically evident, but often amenable to surgical resection (25/49, 51% of cases). In contrast, PET/CT was not effective at predicting complete response to treatment with an accuracy of only 50%. Conclusions In the largest single institution regional therapy series reported to date, we found that while ILI is effective, and well-tolerated, HILP is a more definitive way to control advanced disease.

    Long-term outcome was reviewed in 266 consecutive patients with metastatic non-seminomatous germ cell tumours treated at a single institution. The overall 3 year survival was 77%, and 3 year progression-free survival was 71%. Multivariate analysis identified the following clinical features as independent prognostic factors: the presence of liver, bone or brain metastasis, serum human chorionic gonadotropin > or = 10000 U l-1 and/or alpha-fetoprotein > or = 1000 ng ml-1, a mediastinal mass > 5 cm and the presence of 20 or more lung metastases. Age was not of prognostic significance. Patients without any of the above poor-risk factors had a 3 year survival of 91% regardless of etoposide- or vinblastine-containing chemotherapy compared with 61% for the remaining patients. However, etoposide-containing protocols led to significantly improved survival in patients with at least one poor risk factor. After 612 patient-years of observation no case of secondary leukaemia was observed among 119 surviving patients who had received etoposide as part of their treatment. With a median follow-up of 93 months, five patients developed a second germ cell tumour, two patients nongerm cell malignancies. Fourteen patients relapsed after a disease-free interval of more than 2 years, and nine patients died more than 5 years after commencement of treatment underscoring the need to report long-term results. There is some evidence that cumulative experience translates into improved survival and cure rates for patients with poor-risk metastatic disease. PMID:8883418

    Background Neuroendocrine tumors (NETs) metastatic to the liver are treated with transarterial radioembolization (TARE) using yttrium-90 (Y-90) microspheres or transarterial chemoembolization (TACE). However the criteria for patient selection are not well defined. We sought to determine if Ki67 score could help select patients for one therapy over the other in the management of hepatic neuroendocrine metastases. Methods Single institution analysis of patients treated with Y-90 or TACE between 2001 and 2014. Pathologists blinded to clinical information performed Ki67 staining. Data were analyzed using multivariate association for survival outcomes. Results Amongst 72 patients (male: 39, female: 33, median age: 57 years) with metastatic NET, the most common site of origin was small bowel (n=35, 49%), while pancreas constituted 32% (n=23). Forty-four patients were treated with Y-90 (61%) and 28 patients received TACE (39%). Ki67 score was available in 28 patients (64%) treated with Y-90 and 16 patients (57%) with TACE. Within Y-90 group, there was greater use of Sandostatin (95% vs. 75%, P=0.02) and less number of total treatments completed (89% vs. 46%, P<0.001). There was no significant difference in overall survival (OS) between Y-90 and TACE when used without selection (median, 69 vs. 82 months, P=0.47). When adjusted for Ki67, patients with Ki67 score ≥3% had better OS with Y-90 compared to TACE (HR, 0.1; CI, 0.01–0.9), however for Ki67 <3%, OS was better when treated with TACE compared to Y-90 (HR, 13.5; CI, 1.22–148.87). Conclusions There is significant interaction between Ki-67 score and liver-directed treatment benefit in patients with hepatic neuroendocrine metastases. Ki-67 score ≥3% predicts greater benefit with Y-90 and a Ki-67 score <3% predicts greater benefit with TACE. PMID:27284478

    RNF2 (ring finger protein 2) is frequently overexpressed in several types of human cancer, but the status of RNF2 amplification and expression in urothelial carcinoma of the bladder (UCB) and its clinical/prognostic significance is unclear. In this study, immunohistochemical analysis and fluorescence in situ hybridization (FISH) were used to examine the expression and amplification of RNF2 in 184 UCB patients after radical cystectomy. Overexpression of RNF2 was observed in 44.0% of UCBs and was found to significantly associate with shortened overall and cancer-specific survival (P < 0.001). In different subsets of UCBs, RNF2 overexpression was also identified as a prognostic indicator in patients with pT1, pT2, pN(−), and/or negative surgical margins (P < 0.05). Importantly, RNF2 overexpression together with pT status and surgical margin status provided significant independent prognostic parameters in multivariate analysis (P < 0.01). FISH results showed amplification of RNF2 in 8/79 (10.1%) of informative UCB cases. Additionally, RNF2 overexpression was significantly associated with RNF2 gene amplification (P = 0.004) and cell proliferation (P = 0.003). These findings suggested that overexpression of RNF2, as examined by immunohistochemical analysis, might serve as a novel prognostic biomarker and potential therapeutic target for UCB patients who undergo radical cystectomy.

    Purpose: To conduct a retrospective analysis within a large university teaching hospital, comparing outcomes between patients receiving either radical surgery or radiotherapy as curative treatment for bladder cancer. Patients and Methods: Between March 1996 and December 2000, 169 patients were treated radically for muscle-invasive bladder cancer. Data were collected from patient notes. Statistical analyses were performed using Kaplan-Meier methods and Cox proportional hazards regression analysis to compare radiotherapy and surgical outcome data. Results: There was no difference in overall, cause-specific, and distant recurrence-free survival at 5 years between the two groups, despite the radiotherapy group being older (median age, 75.3 years vs. 68.2 years). There were 31 local bladder recurrences in the radiotherapy group (24 solitary), but there was no significant difference in distant recurrence-free survival. In a more recent (2002-2006) cohort, the median age of radiotherapy patients but not the cystectomy patients was higher than in the 1996-2000 cohort (78.4 years vs. 75.3 years for radiotherapy and 67.9 years vs. 68.2 years for surgery). Conclusions: Although the patients undergoing radical cystectomy were significantly younger than the radiotherapy patients, treatment modality did not influence survival. Bladder cancer patients are an increasingly elderly group. Radical radiotherapy is a viable treatment option for these patients, with the advantage of organ preservation.

    Pancreatic adenocarcinoma is the fourth leading cause of cancer death. Recently, MM-398 (nanoliposomal irinotecan) was shown to be associated with significant improvement in outcome measures with acceptable toxicities when combined with 5-fluorouracil (5-FU)/leucovorin (LV) compared to 5-FU/LV alone in patients failing one line of gemcitabine-based therapy. There is a paucity of data evaluating the role of irinotecan in combination with 5FU in advanced pancreas cancer (APC). We performed a retrospective analysis of all patients who received mFOLFIRI (minus bolus 5FU and LV). All patients with metastatic disease who had failed at least one line of gemcitabine-based therapy prior to receiving mFOLFIRI were included in this study. Descriptive statistics were used to assess the continuous variables and adverse events (AEs), and Kaplan-Meier methods were used to calculate the median progression-free survival (PFS) and overall survival (OS). Forty patients were included in this analysis. Patients received 1-5 lines of prior therapy (25 % with more than 3 lines of prior therapy). The mean age at diagnosis was 60, and 98 % had ECOG of 1. The mean CA 19-9 at the start of therapy was 33,169 U/ml. The median PFS was 2.59 months [95 % confidence interval (CI) (1.90, 3.54)], and OS was 4.75 months [95 % CI (3.14, 8.98)]. The most common AEs included fatigue (98 %), neuropathy (83 %), anorexia (68 %), nausea (60 %) and constipation (55 %). Grade 3 toxicities included fatigue (13 %) and rash (3 %). There were no observed grade 4 toxicities. In this single-institution retrospective analysis, mFOLFIRI was found to be both tolerable and relatively effective in a heavily pretreated patient population with APC. Future prospective studies should consider evaluating the role of mFOLFIRI in refractory APC. PMID:26995224

    Purpose: Local-regional failures (LF) following radical cystectomy (RC) plus pelvic lymph node dissection (PLND) with or without chemotherapy for invasive urothelial bladder carcinoma are more common than previously reported. Adjuvant radiation therapy (RT) could reduce LF but currently has no defined role because of previously reported morbidity. Modern techniques with improved normal tissue sparing have rekindled interest in RT. We assessed the risk of LF and determined those factors that predict recurrence to facilitate patient selection for future adjuvant RT trials. Methods and Materials: From 1990-2008, 442 patients with urothelial bladder carcinoma at University of Pennsylvania were prospectively followed after RC plus PLND with or without chemotherapy with routine pelvic computed tomography (CT) or magnetic resonance imaging (MRI). One hundred thirty (29%) patients received chemotherapy. LF was any pelvic failure detected before or within 3 months of distant failure. Competing risk analyses identified factors predicting increased LF risk. Results: On univariate analysis, pathologic stage {>=}pT3, <10 nodes removed, positive margins, positive nodes, hydronephrosis, lymphovascular invasion, and mixed histology significantly predicted LF; node density was marginally predictive, but use of chemotherapy, number of positive nodes, type of surgical diversion, age, gender, race, smoking history, and body mass index were not. On multivariate analysis, only stage {>=}pT3 and <10 nodes removed were significant independent LF predictors with hazard ratios of 3.17 and 2.37, respectively (P<.01). Analysis identified 3 patient subgroups with significantly different LF risks: low-risk ({<=}pT2), intermediate-risk ({>=}pT3 and {>=}10 nodes removed), and high-risk ({>=}pT3 and <10 nodes) with 5-year LF rates of 8%, 23%, and 42%, respectively (P<.01). Conclusions: This series using routine CT and MRI surveillance to detect LF confirms that such failures are relatively common

    Objectives Radical cystectomy (RC) is the standard treatment for muscle-invasive Urothelial carcinoma of the bladder (UCB). Tri-modality bladder preserving therapy (BPT) is an alternative to RC, but randomized comparisons of RC versus BPT have proven infeasible. To compare RC versus BPT, we undertook an observational cohort study using registry and administrative claims data from the SEER-Medicare database. Methods We identified patients age 65 years or older diagnosed between 1995 and 2005 who received RC (n=1,426) or BPT (n=417). We examined confounding and stage misclassification in the comparison of RC and BPT using multivariable adjustment, propensity score-based adjustment, instrumental variable (IV) analysis and simulations. Results Patients who received BPT were older and more likely to have comorbid disease. After propensity score adjustment, BPT was associated with an increased hazard of death from any cause (HR 1.26; 95% CI, 1.05 – 1.53) and from bladder cancer (HR 1.31; 95% CI, 0.97 – 1.77). Using the local area cystectomy rate as an instrument, IV analysis demonstrated no differences in survival between BPT and RC (death from any cause HR 1.06; 95% CI, 0.78 – 1.31; death from bladder cancer HR 0.94; 95% CI, 0.55 – 1.18). Simulation studies for stage misclassification yielded results consistent with the IV analysis. Conclusions Survival estimates in an observational cohort of patients who underwent RC versus BPT differ by analytic method. Multivariable and propensity score adjustment revealed greater mortality associated with BPT relative to RC, while IV analysis and simulation studies suggest that the two treatments are associated with similar survival outcomes.

    Beliefs frequently undergo revisions, especially when new pieces of information are true but inconsistent with current beliefs. In previous studies, we showed that linguistic asymmetries provided by relational statements, play a crucial role in spatial belief revision. Located objects (LO) are preferably revised compared to reference objects (RO), known as the LO-principle. Here we establish a connection between spatial belief revision and grounded cognition. In three experiments, we explored whether imagined physical object properties influence which object is relocated and which remains at its initial position. Participants mentally revised beliefs about the arrangements of objects which could be envisaged as light and heavy (Experiment 1), small and large (Experiment 2), or movable and immovable (Experiment 3). The results show that intrinsic object properties are differently taken into account during spatial belief revision. Object weight did not alter the LO-principle (Experiment 1), whereas object size was found to influence which object was preferably relocated (Experiment 2). Object movability did not affect relocation preferences but had an effect on relocation durations (Experiment 3). The findings support the simulation hypothesis within the grounded cognition approach and create new connections between the spatial mental model theory of reasoning and the idea of grounded cognition.

    Background: Patient outcomes and predictors of success after revision anterior cruciate ligament (ACL) reconstruction are currently limited in the literature. Existing studies either have a small study size or are difficult to interpret because of the multiple surgeons involved in the care of the study sample. Purpose: To determine patient outcomes and predictors of success or failure after a single-stage revision ACL reconstruction by a single fellowship-trained senior surgeon at a single institution. Study Design: Case series; Level of evidence, 4. Methods: A total of 78 patients who underwent revision ACL reconstruction by a single surgeon from 2010 to 2014 were contacted and available for follow-up. The mean time from revision procedure to follow-up was 52 months. Those patients who were able to participate in the study sent in a completed Tegner activity level scale, International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form, and IKDC Current Health Assessment Form. The patients’ medical records were also thoroughly reviewed. Results: Five patients had subsequent failure after revision surgery. The median Tegner score was 6 at follow-up, and the mean subjective IKDC score was 72.5. There was no statistically significant difference in outcome scores when comparing revision graft type, body mass index, sex, need for bone grafting, and time from failure to revision. Patients with failures after primary ACL reconstruction secondary to a traumatic event were found to have statistically significantly higher IKDC scores (mean, 76.6) after revision when compared with nontraumatic failures (mean, 67.1), even when controlling for confounders (P < .017). Conclusion: Revision ACL reconstruction is effective in improving patient activity levels and satisfaction. However, the subjective IKDC results are quite variable and likely based on multiple factors. Patients with traumatic injuries contributing to graft failure after primary ACL reconstruction

    Background: Benefits of adjuvant chemotherapy (AC) and extent of pelvic lymph node dissection (PLND) in radical cystectomy (RC) are debated. Results from randomized trials are still expected. Objective: To analyze the effects of AC and PLND in two academic centers with opposite policies regarding their use. Methods: 581 bladder cancer patients who underwent RC without neoadjuvant chemotherapy, from Toronto (University Health Network), Canada, and Turku University Hospital, Finland were included. Disease specific survival (DSS) and failure patterns were assessed. Results: Centers differed in PLND rate (93% and 36% in Toronto and Turku respectively, p <  0.001), PLND extent (≥10 removed nodes, 58% vs. 8%, p <  0.001) and AC rate (21% vs. 2%, p <  0.001). Survival between centers among pT≤1 or pT4 patients was similar. pT3 patients in Toronto had an improved 10 year DSS (43% vs. 22%, p = 0.025). Distant failures were less common after AC (HR 0.56, 95%  CI 0.33–0.98, p <  0.042). In node positive (N+) patients, mortality was significantly higher in Turku (HR 2.19, 95%  CI 1.44–3.34, p <  0.001) and lower in patients receiving AC (HR 0.60, 95%  CI 0.37–0.99, p = 0.044). 41% DSS at 10 years was observed in N+ Toronto patients. Limitations included the non-randomized retrospective design and absence of propensity score analysis. Conclusion: Combining AC and PLND to RC is associated with improved survival in pT3 and N+ patients. PLND did not affect survival independently but helps in selecting patients for AC. Our data adds to the growing body of evidence supporting the usefulness of AC in addition to PLND in high risk patients operated by cystectomy. PMID:27376145

    Introduction: This study evaluated the feasibility and safety of open radical cystectomy (RC) under combined regional anesthesia (CRA) in high-risk octogenarian patients. Methods: We retrospectively evaluated the medical records of high-risk, octogenarian bladder cancer patients submitted to open RC with CRA. Demographic and clinical data, intraoperative parameters and perioperative and postoperative complications were recorded using the Clavien-Dindo classification. Results: In total, 14 male and 4 female patients, with a median age of 82.5 years were enrolled. Ureterocutaneostomy was performed in 15 patients and Bricker ileal conduit in the remaining 3. Operative time ranged from 97 to 184 minutes. Five patients were transfused and no major intraoperative complications occurred. Postoperative complications 30 days later included ileus (Grade II) in 3 patients, surgical trauma infection in 1 patient (Grade II), respiratory infection in 2 patients (Grade III), and hydronephrosis with concurrent urinary tract infection in 3 patients (Grade III). No deaths occurred. Conclusions: Our study showed that octogenarian, high-risk bladder cancer patients with indications for RC can safely undergo the surgical procedure under CRA, without apparent increase in major complications.

    Revision rhinoplasty is a complex operation with many variables that may influence the final esthetic and functional outcome of the procedure. Cartilage forms the structural framework of the lower two-thirds of nose and is essential for long-term support and maintenance of a patent nasal airway. The use of autologous cartilage grafting is the primary source of this material, limited by donor site quantity, quality, and harvest morbidity. Alloplastic materials, solid and injectable, are often used for augmentation purposes and may have devastating consequences. This article discusses past and current treatment concepts for various nasal deformities using available autologous grafting techniques. PMID:27400847

    Purpose Postoperative ileus (POI) is common following bowel resection for radical cystectomy with ileal conduit (RCIC). We investigated perioperative factors associated with prolonged POI following RCIC, with specific focus on opioid-based analgesic dosage. Materials and Methods From March 2007 to January 2013, 78 open RCICs and 26 robot-assisted RCICs performed for bladder carcinoma were identified with adjustment for age, gender, American Society of Anesthesiologists grade, and body mass index (BMI). Perioperative records including operative time, intraoperative fluid excess, estimated blood loss, lymph node yield, and opioid analgesic dose were obtained to assess their associations with time to passage of flatus, tolerable oral diet, and length of hospital stay (LOS). Prior to general anaesthesia, patients received epidural patient-controlled analgesia (PCA) consisted of fentanyl with its dose adjusted for BMI. Postoperatively, single intravenous injections of tramadol were applied according to patient desire. Results Multivariate analyses revealed cumulative dosages of both PCA fentanyl and tramadol injections as independent predictors of POI. According to surgical modality, linear regression analyses revealed cumulative dosages of PCA fentanyl and tramadol injections to be positively associated with time to first passage of flatus, tolerable diet, and LOS in the open RCIC group. In the robot-assisted RCIC group, only tramadol dose was associated with time to flatus and tolerable diet. Compared to open RCIC, robot-assisted RCIC yielded shorter days to diet and LOS; however, it failed to shorten days to first flatus. Conclusion Reducing opioid-based analgesics shortens the duration of POI. The utilization of the robotic system may confer additional benefit. PMID:25048497

Disease-free survival (DFS) and overall survival (OS) were determined by using a Cox proportional hazards model that included the number of excised lymph nodes, the presence of pathological lymph node metastasis, the anatomical level of positive nodes, the number of positive lymph nodes, lymph node density, and the presence of skip metastasis. Results The mean number of lymph nodes removed per patient was 29.4±9.3. Lymph node positivity was detected in 85 patients (34.1%). The mean follow-up duration was 44.9±27.4 months (2-93 months). Five-year estimated OS and DFS for the 85 patients were 62.6% and 57%, respectively. Three of 29 lymph node-positive patients (10.3%) had skip metastasis. Only lymph node positivity had a significant effect on 5-year OS and DFS (p<0.001). No difference in OS and DFS was found between the three patients with skip metastasis and other lymph node-positive patients. Other factors related to lymph node status had no significant effect on 5-year OS and DFS. Conclusions No factors related to lymph node status predict DFS and OS, except for lymph node positivity. OS and DFS were comparable between patients with skip metastasis and other lymph node-positive patients. PMID:25964836

    Objective To report our experience with an improved technique of laparoscopic radical cystectomy (LRC) and orthotopic ileal neobladder reconstruction, evaluating the perioperative and pathological outcomes. Methods We retrospectively reviewed the data of 56 cases who underwent radical cystoprostatectomy followed by construction of an orthotopic U-shaped ileal neobladder between August 2010 and December 2014. These data include intraoperative data, early and long-term postoperative complications, neobladder function, urinary continence and oncologic results. Also the key innovative procedure was introduced with details. Results The median time of the overall procedure was 212 min. The median estimated blood loss was 171 mL. The median hospitalization time after the operation was 21 days. Complications included two cases of unilateral ureter-pouch anastomotic strictures, one case of bilateral ureteral stricture, three cases of vesicourethral anastomotic strictures and three cases of vesicourethral leakage. The mean maximum pouch capacity was 446±32 mL, and pouch pressure at capacity was 18.1±2.6 cmH2O. The Qmax was 14±1.2 mL/s, and the mean post-void residual was 25±10 mL. There were nine cases of night-time incontinence at 3 months post-operatively. Negative surgical margins of the bladder specimens were achieved in all patients. During a follow-up period of 3 to 44 months (average 32.6 months), local recurrence was found in two patients and distant metastasis was occurred in another three patients. Conclusions Our preliminary experience showed that pure LRC with non-absorbable titanium staples assisted orthotopic U-shape ileal neobladder reconstruction is feasible based on perioperative data and oncologic features.

    Objective: Striatocapsular infarction is an uncommon form of deep hemispheric strokes. We analyzed the clinical presentation of this stroke to determine its core features and neurological outcome. Material and methods: This prospective, observational, short-term longitudinal study was carried out from November 1, 2009 to October 30, 2011 in the department of neurology, Sulaimaniya general teaching hospital, Iraq and involved 13 consecutive Kurdish patients who were diagnosed with striatocapsular infarction radiologically; all patients underwent routine blood tests, resting 12-lead ECG, transthoracic echocardiography, and urgent non-contrast CT brain scanning at the time of admission. All patients were reassessed clinically after 3 months. Results: Nine patients (69%) were females and 7 patients (53%) were older than 50 years of age. Infarction of the right lenticular nucleus was more common than the left one. Severe flaccid hemiplegia dominated the clinical presentation. Speech and language dysfunction were found in 4 patients (30%) while inattention and neglect were detected in 8 patients (61%). At 3 months, 4 patients were bed-ridden and 4 were wheel-chair bound; dystonia and involuntary movements did not occur. Only the patient with bilateral infarction demonstrated Parkinsonism. Conclusion: Striatocapsular infraction in Iraqi Kurdish patients was more common in females and at the right lenticular nucleus. Hypertension, smoking, and hypercholesterolemia were the commonest risk factors. Dense hemiplegia was the commonest presentation; the functional outcome was poor in the majority. After 3 months of the ischemic event, involuntary movements and dystonia were not seen, and Parkinsonism was found in one patient only. PMID:23322963

    A committee composed of members of The American Dietetic Association and the American Diabetes Association has revised Exchange List for Meal Planning. Changes were made, as deemed necessary, on the basis of nutritional recommendations for persons with diabetes as understood in 1986. Major changes include rewriting the text to make it more useful in the education of persons with diabetes; changing the order of the exchange lists to emphasize a high-carbohydrate, high-fiber diet, as well as to better reflect the order of foods in menu planning; adding symbols to foods high in fiber and sodium; changing nutritive values for the starch/bread and fruit lists; adding lists of combination foods, free foods, and foods recommended only for occasional use; developing a data base; and initiating a plan for field testing and evaluation. The committee also developed a simplified meal planning tool, Healthy Food Choices, to be used for initial or "survival" level education. In poster format, foods are grouped by calories into six food groups. Approximate portion sizes of commonly used foods are listed. Blank lines are provided for the nutrition counselor to write in a suggested menu or meal plan for the client. Because the booklet does not use the word "diabetes" specifically, it is appropriate as a general teaching tool. PMID:3794130

  20. OMB revises overhead rules

    NASA Astrophysics Data System (ADS)

    Katzoff, Judith A.

    After pressure from university administrators, the Office of Management and Budget (OMB) has issued a new plan for saving money on research overhead costs, in place of a controversial proposal that was originally published in February 1986 (Eos, May 20, 1986, p. 481). The agency made the new plan more palatable to administrators and faculty by choosing to cap the rate of reimbursement for the activity that researchers say they find among the most difficult to document: the time they spend on administration of federally sponsored grants and contracts. An amendment to a bill signed by President Ronald Reagan on July 2 might force OMB to make additional concessions to colleges and universities.How much money the federal government would save under this policy is a matter of dispute. The agency's revisions to OMB Circular A-21, “Cost Principles for Educational Institutions,” call for fixing the reimbursement rate at 3% of modified total direct costs for departmental administration work done by “department heads, directors of divisions faculty, and professional staff.” The 3% figure represents about half of the current national average rate of reimbursement for these costs and would lead to federal government savings of $100 million a year, according to OMB.

    Context: In the absence of a community-based study on the spinal tumors in the Valley, medical records of the only Regional Neurosurgical Center are available. Aim: The aim of this study is to establish a hospital-based regional epidemiology of spinal tumors in the Valley since the data are derived from a single institution. Materials and Methods: A retrospective analysis of 531 malignant and nonmalignant tumors of spinal cord, its coverings and vertebrae, which were managed in a Regional Neurosurgical Center under a standard and uniform medical-protocol over 30-year period from 1983 to 2014. Results: The hospital-based incidence for all spinal tumors was 0.24/100,000 persons per year. The malignant spinal cord and vertebral tumors comprised 32.58% (173/531) of all tumors, and benign spinal cord and vertebral tumors comprised 67.42% (358/531). The extradural–intradural tumors such as metastatic lesions and primary malignant vertebral tumors were on rise with 16.38% (87/531) cases. The children below 18 years were 5.46% (29/531), of which 55.17% (16/29) were below 9 years. The most common primary bone malignancy was multiple myeloma (54.54% =12/22). Histopathologically, the most common metastatic deposit in the spinal canal was non-Hodgkin's lymphoma (24.61% =16/65). A mortality of 3.20% (17/531) was noted. Recurrences were noted in 4.90% (26/531), and adjuvant therapies were given to 16.38% (87/531) patients. Conclusion: The malignant spinal cord and vertebral tumors, especially metastatic deposits, are on rise in elderly population. The surgical outcome, in terms of recovery and spinal stability, of benign tumors, is comparatively better than malignant ones. The study reveals a low regional incidence (hospital-based) of spinal tumors. PMID:27365955

    Background Management of hepatocellular carcinoma (HCC) in the Model for End-Stage Liver Disease (MELD) exception era remains regionally variable. Outcomes were compared for patients undergoing transplant versus resection at a single institution in a UNOS region with short wait times for organ availability. Methods All patients who underwent resection of HCC from January 2000 to August 2012 and patients who underwent transplant post-January 2006, during the Milan Criteria (MC)-based MELD exception policy for HCC, were identified. Primary outcomes were overall survival (OS) and recurrence-free survival (RFS). Results Two hundred fifty-seven patients were analyzed, of whom 131 underwent transplant and 126 underwent resection. All transplant patients met MC; 45 (36%) resection patients met MC. Median follow-up time was 30 months. Median wait time to transplant was 55 days; no patients dropped off the waitlist while awaiting an organ. Among patients meeting MC, transplant demonstrated significantly greater 5-year OS (65.7% vs. 43.8%; P = 0.005) and RFS (85.3% vs. 22.7%; P < 0.001) versus resection. For patients with hepatitis C, transplant (n = 87) demonstrated significantly improved 5-year outcomes compared to patients meeting MC who underwent resection (n = 21; OS: 63.5% vs. 23.3%; P = 0.001; RFS: 83.5% vs. 23.7%; P < 0.001). Conclusion In a region with short waitlist times for organ availability, liver transplant is associated with improved survival compared to resection for HCC within MC and should be considered for all patients meeting MC, particularly those with hepatitis C.

    Background Filgrastim biosimilars have recently been introduced into clinical practice. To date biosimilars have demonstrated comparable efficacy and safety as the originator in chemotherapy-induced neutropenia. Published experience in engraftment after autologous stem cell transplantation (ASCT) is limited and concerns relatively few patients. Materials and methods With the aim of assessing the efficacy and the safety of filgrastim biosimilars in post-ASCT bone marrow recovery, we conducted a single institution, retrospective study in 56 lymphoma and myeloma patients who received filgrastim biosimilars (Tevagrastim® and Zarzio®) at standard doses from day 5. We compared our results with recently published data on the originator. A cost analysis of each biosimilar was performed. Results Neutrophil counts recovered in 55 patients. The median number of filgrastim biosimilar vials injected was seven per patient. The median time to neutrophil and platelet recovery was 10 and 12 days, respectively. Twenty-six patients had febrile neutropenia, in half of whom the agent involved was identified. In the cost analysis, the use of Tevagrastim® and Zarzio® was associated with cost reductions of 56% and of 86%, respectively. Discussion Despite differences in CD34+ cell counts and time of starting filgrastim, our results in terms of time to engraftment and median number of vials injected are similar to published data. Comparing our results by single conditioning regimen to recent literature data, the time to engraftment and duration of hospitalisation were equivalent. Significant differences were observed in the incidence of febrile neutropenia, perhaps due to different preventive and prophylactic protocols for infections. Although prospective studies should be performed to confirm our results, filgrastim biosimilars were found to be effective and safe in engraftment after ASCT. PMID:25761321

  4. Perioperative use of crystalloids in patients undergoing open radical cystectomy: balanced Ringer’s maleate versus a glucose 5%/potassium-based balanced solution: study protocol for a randomized controlled trial

    PubMed Central

    2014-01-01

    Background The optimal crystalloid solution to use perioperatively in patients undergoing open radical cystectomy remains unclear. Many of the fluids used for intravenous hydration contain supraphysiologic concentrations of chloride, which can induce hyperchloremia and metabolic acidosis, resulting in renal vasoconstriction and decreased renal function. In addition, patients receiving less fluid and less sodium show faster recovery of gastrointestinal (GI) function after colonic surgery. Methods and design This is an investigator-initiated, single-center, randomized, controlled, parallel group trial with assessor-blinded outcome assessment, in the Department of Urology, University Hospital Bern, Switzerland. The study will involve 44 patients with bladder cancer scheduled for radical cystectomy and urinary diversion. The primary outcome is the duration between the end of surgery and the return of the GI function (first defecation). Secondary outcomes are fluid balance (body weight difference postoperatively versus preoperatively) and the incidence of kidney function disorders according to the Risk – Injury – Failure – Loss - End Stage Renal Disease (RIFLE classification). An equal number of patients are allocated to receive Ringerfundin® solution or a glucose/potassium-based balanced crystalloid solution as baseline infusion during the entire time that intravenous administration of fluid is necessary during the perioperative period. The randomized crystalloid solution is infused at a rate of 1 ml/kg/h until the bladder has been removed, followed by 3 ml/kg/h until the end of surgery. Postoperative hydration is identical in both groups and consists of 1,500 ml of the randomized crystalloid solution per 24 hours. Postoperative patient care is identical in both groups; patients are allowed to drink clear fluids immediately after surgery, and liquid diet is started on postoperative day 1, as well as active mobilization and the use of chewing gum.

    Background and purpose - The surgical treatment of periprosthetic knee infection is generally either a partial revision procedure (open debridement and exchange of the tibial insert) or a 2-stage exchange arthroplasty procedure. We describe the failure rates of these procedures on a nationwide basis. Patients and methods - 105 partial revisions (100 patients) and 215 potential 2-stage revision procedures (205 patients) performed due to infection from July 1, 2011 to June 30, 2013 were identified from the Danish Knee Arthroplasty Register (DKR). Failure was defined as surgically related death ≤ 90 days postoperatively, re-revision due to infection, or not reaching the second stage for a planned 2-stage procedure within a median follow-up period of 3.2 (2.2-4.2) years. Results - The failure rate of the partial revisions was 43%. 71 of the partial revisions (67%) were revisions of a primary prosthesis with a re-revision rate due to infection of 34%, as compared to 55% in revisions of a revision prosthesis (p = 0.05). The failure rate of the 2-stage revisions was 30%. Median time interval between stages was 84 (9-597) days. 117 (54%) of the 2-stage revisions were revisions of a primary prosthesis with a re-revision rate due to infection of 21%, as compared to 29% in revisions of a previously revised prosthesis (p = 0.1). Overall postoperative mortality was 0.6% in high-volume centers (> 30 procedures within 2 years) as opposed to 7% in the remaining centers (p = 0.003). Interpretation - The failure rates of 43% after the partial revision procedures and 30% after the 2-stage revisions in combination with the higher mortality outside high-volume centers call for centralization and reconsideration of surgical strategies.

    We report a very unusual complication of uretero-iliac artery fistula that developed following robotic radical cystectomy (RARC), bilateral extended pelvic lymph node dissection and intracorporeal Studer pouch reconstruction. Our patient was a 54-year-old male who was admitted 1 month after undergoing robotic surgery due to intermittently occurring massive transurethral bleeding necessitating blood transfusion that stopped by itself. Angiography showed a right external iliac artery pseudo-aneurysm and a fistula tract between the pseudo-aneurysm and Wallace type ureteral anostomosis that was successfully treated by an angiographic endovascular stent insertion at this level. Uretero-iliac artery fistula might occur following RARC, bilateral extended pelvic lymph node dissection and intracorporeal Studer pouch reconstruction leading to intermittently massive transurethral bleeding. Angiography and stenting are important for diagnosis and successful treatment of this rare entity. PMID:24069106

    Objective : To retrospectively review the results at minimum ten years after surgery of a consecutive series of total knee arthroplasties (TKAs) performed using a constrained condylar implant in patients with severe coronal plane instability. Materials and Methods : The series comprised of 44 patients (45 knees) who received primary (19 knees) or revision (26 knees) TKA with a constrained condylar implant between 2001 and 2003 at a single institution. Results : There were no revisions or any other surgery related complications at a mean implantation time of 11.0 years. In 38 patients (15 knees in the primary group and 24 knees in the revision group) who were available for clinico-radiographic follow-up at a minimum of ten years, there was no sign of radiographic loosening. Two patients showed cortical hypertrophy at the extension stem tip but none complained of pain around the stem tip. According to the TLKSS score grading, 73% of the patients in the primary group had results categorized as good or excellent, while 54% of the patients in the revision group had fair results. Four patients (one (7%) in the primary group and three (13%) in the revision group) had poor results. The median WOMAC Index was 80.2% (interquartile range: 74.0% - 81.2%) and 74.0% (interquartile range: 72.1% - 75.8%) in the primary and in the revision groups, respectively (p=0.010). Conclusion : This study showed satisfactory clinical outcomes with no re-operations at minimum ten years after implantation in patients who had undergone primary or revision TKA with a condylar constrained implant.

  8. Rayleigh's Scattering Revised

    Kolomiets, Sergey; Gorelik, Andrey

    Mie’s waves while sounding within coincident volumes. Being sensitive to the size of scatters, Mie’s waves can give us additional information about particle size distribution. But how about using several wavelengths corresponding to Rayleigh’s diffraction on scatters only? Can any effects be detected in such a case and what performance characteristics of the equipment are required to detect them? The deceptive simplicity of the negative answer to the first part of the question posed will disappear if one collects different definitions of Rayleigh's scattering and consider them more closely than usually. Several definitions borrowed from the introductory texts and most popular textbooks and articles can be seen as one of the reasons for the research presented in the report. Hopefully, based on the comparison of them all, anyone could easily conclude that Rayleigh's scattering has been analyzed extensively, but despite this extensive analysis made fundamental ambiguities in introductory texts are not eliminated completely to date. Moreover, there may be found unreasonably many examples on how these ambiguities have already caused an error to be foreseen, published on the one article, amplified in another one, then cited with approval in the third one, before being finally corrected. Everything indicated that in the light of all the lesions learned and based on modern experimental data, it is time to address these issues again. After the discussion of ambiguities of Rayleigh's scattering concepts, the development of the corrections to original ideas looks relatively easy. In particular, there may be distinguished at least three characteristic regions of the revised models application from the point of view of the scattered field statistical averaging. The authors of the report suggest naming them Rayleigh’s region, Einstein’s region and the region with compensations of the scattering intensity. The most important fact is that the limits of applicability of all

    This revision of the classification of eukaryotes, which updates that of Adl et al. (2005), retains an emphasis on the protists and incorporates changes since 2005 that have resolved nodes and branches in phylogenetic trees. Whereas the previous revision was successful in re-introducing name stability to the classification, this revision provides a classification for lineages that were then still unresolved. The supergroups have withstood phylogenetic hypothesis testing with some modifications, but despite some progress, problematic nodes at the base of the eukaryotic tree still remain to be statistically resolved. Looking forward, subsequent transformations to our understanding of the diversity of life will be from the discovery of novel lineages in previously under-sampled areas and from environmental genomic information.

    Background and purpose In Norway, the proportion of revision knee arthroplasties increased from 6.9% in 1994 to 8.5% in 2011. However, there is limited information on the epidemiology and causes of subsequent failure of revision knee arthroplasty. We therefore studied survival rate and determined the modes of failure of aseptic revision total knee arthroplasties. Method This study was based on 1,016 aseptic revision total knee arthroplasties reported to the Norwegian Arthroplasty Register between 1994 and 2011. Revisions done for infections were not included. Kaplan-Meier and Cox regression analyses were used to assess the survival rate and the relative risk of re-revision with all causes of re-revision as endpoint. Results 145 knees failed after revision total knee arthroplasty. Deep infection was the most frequent cause of re-revision (28%), followed by instability (26%), loose tibial component (17%), and pain (10%). The cumulative survival rate for revision total knee arthroplasties was 85% at 5 years, 78% at 10 years, and 71% at 15 years. Revision total knee arthroplasties with exchange of the femoral or tibial component exclusively had a higher risk of re-revision (RR = 1.7) than those with exchange of the whole prosthesis. The risk of re-revision was higher for men (RR = 2.0) and for patients aged less than 60 years (RR = 1.6). Interpretation In terms of implant survival, revision of the whole implant was better than revision of 1 component only. Young age and male sex were risk factors for re-revision. Deep infection was the most frequent cause of failure of revision of aseptic total knee arthroplasties. PMID:25267502

    This report is a revision of the previous Hanford Environmental Dose Reconstruction (HEDR) Project modeling approach report. This revised report describes the methods used in performing scoping studies and estimating final radiation doses to real and representative individuals who lived in the vicinity of the Hanford Site. The scoping studies and dose estimates pertain to various environmental pathways during various periods of time. The original report discussed the concepts under consideration in 1991. The methods for estimating dose have been refined as understanding of existing data, the scope of pathways, and the magnitudes of dose estimates were evaluated through scoping studies.

    2014-10-01

    Unicompartmental arthroplasty is an efficient and approved treatment option of unicompartmental arthritis of the knee, being performed with increasing frequency worldwide. Compared to total knee replacement, there are several advantages such as faster recovery, lower blood loss, better functional outcome and lower infection rates. However, higher revision rates are a frequent argument against the use of unicompartmental arthroplasty. The following article gives an overview of failure mechanisms and strategies for revision arthroplasty. This article is based on a selective literature review including PubMed and relevant print media. Our own clinical experience is considered as well. PMID:25209015

    The purpose of this paper is to report on revised cross-section evaluations for 17 nuclides that have been prepared for ENDF/B-VI Revision 2. The nuclides considered include five fission products and various isotopes of cadmium and hafnium. The previous ENDF/B-VI evaluations for these 17 nuclides were carried over from ENDF/B-V and were completed in the 1974--1980 time period. By utilizing the experimental data that have become available since 1980 the revised evaluations will result in significant improvements in the evaluated nuclear data files. The primary emphasis was placed on the resolved and unresolved resonance regions, but new experimental data were also used to improve the cross sections for energies above the unresolved resonance region. Negative elastic scattering cross sections were encountered in some of the previous evaluations; since the revised evaluations use multilevel Breit-Wigner (MLBW) parameters, rather than single-level Breit-Wigner (SLBW), this problem is eliminated.

    This paper describes CLIPS-R, a theory revision system for the revision of CLIPS rule-bases. CLIPS-R may be used for a variety of knowledge-base revision tasks, such as refining a prototype system, adapting an existing system to slightly different operating conditions, or improving an operational system that makes occasional errors. We present a description of how CLIPS-R revises rule-bases, and an evaluation of the system on three rule-bases.

    1995-12-31

    Fatigue cracking has been a principal cause of damage to North Sea structures and consequently considerable attention has been given to the development of guidance for the prediction of fatigue performance. The fatigue guidance of the Offshore Safety Division of the Health and Safety Executive (HSE) was recently revised and published, following a significant offshore industry review in the period 1987 to 1990, and is based on the results of a considerable amount of research and development work on the fatigue behavior of welded tubular and plated joints. As a result of this review, the revised fatigue guidance incorporates several new clauses and recommendations. The revised recommendations apply to joint classification, basic design S-N curves for welded joints and cast or forged steel components, the thickness effect, the effects of environment and the treatment of low and high stress ranges. Additionally, a new appendix on the derivation of stress concentration factors is included. The new clauses cover high strength steels, bolts and threaded connectors, moorings, repaired joints and the use of fracture mechanics analysis. This paper presents an overview of the revisions to the fatigue guidance, the associated background technical information and aspects of the fatigue behavior of offshore structures which are considered to require further investigation. 67 refs., 7 figs., 8 tabs.
