Quantification of potential biomarker expression was performed Ethan zorn survivor nude radical prostatectomy samples Ethan zorn survivor nude arrayed as 0. In prostate cancer, treatment-related decisions are complex and may impact post-treatment quality of life QOL. Secondary outcomes included the impact of case quartile on pT2 and pT3 PSM rates, operative time, estimated blood loss, and length of Etuan stay. The hepatitis C and treatment effects are likely driven by a greater proportion of immunocompromised patients having hepatitis C and being on protease inhibitors rather than either the treatment or hepatitis C infection contributing directly. It has been increasingly recognized that the surgeon plays an important role in functional and oncological outcomes post-robotic-assisted radical prostatectomy RARP.

An age effect analysis was pre-specified to investigate the efficacy and safety of ENZA vs. The primary efficacy endpoint was centrally assessed progression-free survival PFS and a secondary efficacy endpoint was time to prostate-specific antigen PSA progression. BIC in younger median ENZA showed safety consistent with its known safety profile in both age subgroups. In active surveillance AS , practitioners delay curative treatment in low-risk patients until there is evidence of disease progression, at which time active treatment is initiated.
Although the uptake of AS appears to be increasing, the actual uptake in Canada remains largely unknown. The aim of this study is to examine practice patterns around the use of AS in low-risk prostate cancer in Canada. In addition, we examined regional variations in uptake of AS, as well as predictors of AS uptake and persistent use of AS for 12 months. For incident cases, clinical and pathological information was collected via chart review prospectively for 12 months following the last biopsy of Eligibility for AS and treatment trends by region were compared using chi-square tests for categorical variables and the ANOVA test for continuous variables.
Univariate and multivariate logistic regression was used to examine predictors of choosing AS upfront versus active treatment within six months of diagnosis and to predict the likelihood of continuing on AS for 12 months. Of patients, patients mean age 64 years were incident cases and were eligible for AS. Over three-quarters There were significant differences in uptake of AS by region range Maintenance with AS over 12 months differed by region, ranging from Predictors of maintenance with AS over 12 months included age, region, and number of positive cores.
In all, Among patients who underwent AS for at least six months, 88 Distribution of incident patients by initial active surveillance AS vs. Castrate-resistant prostate cancer CRPC patients pts with metastatic bone disease MBD risk significant morbidity, including symptomatic skeletal events SSEs palliative radiation, pathological fracture, surgery to bone, and spinal cord compression , and require substantial healthcare resource use HRU.
Median survival from MBD onset was Median time to first SSE was Pts presented a mean of 2. We compared ORP and RARP with respect to surrogate cancer control, functional preservation, perioperative, and healthcare utilization outcomes in men treated at the University of Alberta. A prospective analysis of data from the University of Alberta Radical Prostatectomy Database was performed.
The surgeon selected the surgical approach. Functional preservation outcomes were one-year urinary and erectile function preservation rates. Perioperative outcomes were day complication and blood transfusion rates. Complete data were evaluable for out of patients. The median followup duration was 48 months. Baseline age 62 years vs. In men treated at a Canadian academic centre, RARP provided superior cancer control, functional preservation, and blood product transfusion rates compared to ORP.
Further analyses designed to examine mechanisms of differences in outcomes is underway. Complications, including cardiovascular disease and skeletal-related events SREs , from androgen-deprivation therapy ADT in the treatment of prostate cancer are well-described, but the role of primary therapy and its interaction with ADT is unknown among patients treated for clinically localized prostate cancer.
We examined long-term rates of cardiovascular and SREs for these patients. We categorized treatment exposure according to primary treatment and receipt of ADT. We measured the cumulative incidence of cardiovascular and skeletal-related complications. Among 60 men, 14 underwent primary surgery and 45 underwent radiotherapy. After a median followup of 6.
Patients receiving ADT had an increased risk of coronary heart disease, sudden cardiac death, fractures, and fractures requiring hospitalization adjusted hazard ratios 1. We did not find evidence of significant interaction between local and systemic treatments. Cardiovascular disease and SREs are important complications for the treatment of clinically localized prostate cancer.
The risk is higher among those treated with radiation or ADT and should be considered when discussing the risks and benefits of treatment for localized prostate cancer. Biochemical recurrence within 2. Consequently, predicting the likelihood that biochemical recurrence would not occur within 2.
Our objective was to develop biomarkers in non-invasive specimens that would improve the prediction of early biochemical recurrence BCR , defined as prostate-specific antigen PSA greather than 0.
Prospectively collected expressed prostatic secretion EPS specimens prior to robot-assisted radical prostatectomy. The data was modeled using logistic regression, random forests and cross-validated.
A baseline model using biopsy Gleason sum and serum PSA value was constructed with logistic regression. The difference in the values is statistically significant, with a p value of 0. Random forest analysis was also applied to the data using all variables available, however, a statistical comparison showed that the logistic regression classifier was preferred. PPA and PCA3 RNA are effective biomarkers in EPS specimens for the pre-surgical prediction of early biochemical recurrence after surgery, which should have use in counselling patients prior to prostatectomy.
Conditional relapse-free survival cRFS estimates were calculated by using the multiplicative law of probability at time periods coinciding with our AS followup protocol.
We stratified patients according to validated risk factors for relapse. We used linear regression to determine cRFS trends over time. Models were validated using discrimination and calibration. All models demonstrated good discrimination and calibration.
There is a lack of validated quality metrics to evaluate the care of patients receiving renal cancer surgery. To address this knowledge gap, the Kidney Cancer Research Network of Canada defined a list of quality indicators QI to assess hospital-level performance. We have risk-adjusted these QIs to benchmark renal cancer surgical care at Canadian academic centres. A cohort study was performed using CKCis, which collects data from 15 Canadian hospitals.
To benchmark performance, the expected rate for a defined QI for each hospital was determined through multivariate regression modeling of patient-, tumour-, and treatment-related variables. Hospitals in CKCis display variation in performance for several renal cancer QIs with a minority performing worse than expected. In our multidisciplinary bladder cancer clinic MDBCC , patients have the opportunity to discuss various treatment options, including radical cystectomy RC or bladder-sparing trimodal therapy TMT: endoscopic resection, radiotherapy, and chemotherapy.
Although reports have shown comparable outcomes of TMT to cystectomy, no direct comparison to RC has been published and no randomized studies are available.
We report our long-term outcomes of multidisciplinary care, comparing TMT to surgery using propensity-matched analyses. Overall survival OS and disease-specific survival DSS were assessed with Cox proportional hazards modeling and competing risk analysis, respectively. Median age of the cohort was With a median followup time of 3. Five-year DSS was BC patients should be offered the possibility to discuss various treatment options.
Despite the validation of these scoring systems, they are infrequently used in clinical practice. The objective of this study was to determine how renal tumour scoring systems compare to clinical judgement in predicting time required for tumour removal and kidney reconstruction during partial nephrectomy.
A consecutive cohort of partial nephrectomy patients treated at The Ottawa Hospital was included. Preoperative axial images were reviewed by four urologic oncologists who independently rated the complexity of a partial nephrectomy from 1—10 to generate a clinical judgment score.
The time to complete tumour resection and renal reconstruction during partial nephrectomy was prospectively recorded. If renal hypothermia was used, the time to cool the kidney was not included. During the study period, partial nephrectomies were performed. The mean partial nephrectomy complexity score based on clinical judgment was 3. There was good agreement between surgeons in assessing tumour complexity intraclass correlation coefficient 0.
Mean resection and reconstruction time was 24 minutes SD 10 minutes. The correlation between clinical judgment score and time was 0. The correlation between renal tumour scoring systems and time was 0. Renal tumour scoring systems are not better than clinical judgment in predicting time required for tumour resection and renal reconstruction during partial nephrectomy. Urological dogma dictates that washings collected from the urinary tract for cytological assessment must be performed without interference from contrast agents that may alter cellular integrity and diagnostic interpretation.
In practice, the initial contrast used to outline the upper tracts is commonly discarded with subsequent saline washings sent for cytology. We hypothesize that contrast washings do not affect the morphology of urothelial carcinoma cells or the integrity of cytology interpretation. Urine obtained from 1 a human xenograft bladder cancer model using UC-3 cells; 2 patients with urothelial carcinoma; and 3 patients without urothelial cancer were subjected to various experimental solutions water, saline, urine, and dilutions of contrast media for different exposure times.
After exposure to various different solutions, cells underwent cytological analysis to assess morphologic and degenerative changes. No cytological differences were seen when cells were exposed to ionic, hyperosmolar, and non-ionic low-osmolar contrast agents for any exposures up to five minutes.
Cells exposed to mixtures of contrast agents and urine also demonstrated no evidence of degenerative change. Cells exposed to water for greater than one minute demonstrated significant hydropic degeneration impacting cytological interpretation. At 40 minutes or later, all reagents except urine caused severe degeneration. Commonly used contrast agents have no effect on urinary cytology up to five minutes. Contrast washings of the urinary tract should not be discarded and can be sent for cytological diagnosis if fixed within this time period.
All malignant lesions were classified as less aggressive malignancies as either Fuhrman Grade 1 or 2 with no evidence of progression to Bosniak IV.
On average, a larger lesion size trended towards pathological identification of benign complex cysts in comparison to a RCC 5. Our study also identified that all identified Bosniak III lesions were of low Fuhrman grade, with no evidence of progression, which suggests a better prognosis.
No patient in this study developed metastatic disease within the three year followup period.
