Obesity and Complication Risk From Radical Cystectomy: Identifying a Body Mass Index Threshold.

PURPOSE: There are conflicting reports regarding radical cystectomy complication risk from obesity subcategories, and a BMI threshold below which complication risk is notably reduced is undefined. A BMI threshold may be helpful in prehabilitation to aid patient counseling and inform weight loss strategies to potentially mitigate obesity-associated complication risk. This study aims to identify such a threshold and further investigate the association between BMI subcategories and perioperative complications from radical cystectomy. MATERIALS AND METHODS: Data were extracted from the Canadian Bladder Cancer Information System, a prospective registry across 14 academic centers. Five hundred and eighty-nine patients were analyzed. Perioperative (≤90 days) complications were compared between BMI subcategories. Unconditional multivariable logistic regression and cubic spline analysis were performed to determine the association between BMI and complication risk and identify a BMI threshold. RESULTS: Perioperative complications were reported in 51 (30%), 97 (43%), and 85 (43%) normal, overweight, and obese patients (P = .02). BMI was independently associated with developing any complication (OR 1.04 95% CI 1.01, 1.07). Predicted complication risk began to rise consistently above a BMI threshold of 34 kg/m2. Both overweight (OR 2.00 95% CI 1.26-3.17) and obese (OR 1.98 95% CI 1.24-3.18) patients had increased risk of complications compared to normal BMI patients. CONCLUSIONS: Complication risk from radical cystectomy is independently associated with BMI. Both overweight and obese patients are at increased risk compared to normal BMI patients. A BMI threshold of 34 kg/m2 has been identified, which may inform prehabilitation treatment strategies.

Prognostic value of urinary prostate cancer antigen 3 (PCA3) during active surveillance of patients with low-risk prostate cancer receiving 5α-reductase inhibitors.

OBJECTIVES: To determine the clinical performance of the urinary prostate cancer antigen 3 (PCA3) test to predict the risk of Gleason grade re-classification amongst men receiving a 5α-reductase inhibitor (5ARI) during active surveillance (AS) for prostate cancer. PATIENTS AND METHODS: Patients with low-risk prostate cancer were enrolled in a prospective Phase II study of AS complemented with prescription of a 5ARI. A repeat biopsy was taken within the first year and annually according to physician and patient preference. In all, 90 patients had urine collected after digital rectal examination of the prostate before the first repeat biopsy. The PCA3 test was performed in a blinded manner at a central laboratory. RESULTS: Using a PCA3-test score threshold of 35, there was a significant difference (P < 0.001) in the risk of being diagnosed with Gleason ≥7 cancer during a median of 7 years of follow-up. Adjusted Cox regression and Kaplan-Meier analyses also showed a significantly higher risk of upgrading to Gleason ≥7 during follow-up for those with a higher PCA3-test score. CONCLUSION: The urinary PCA3 test predicted Gleason grade re-classification amongst patients receiving a 5ARI during AS for low-risk prostate cancer.

Clinical outcomes in octogenarians treated with docetaxel as first-line chemotherapy for castration-resistant prostate cancer.

AIM: To assess clinical outcomes in octogenarians treated with docetaxel (DOC) for metastatic castration-resistant prostate cancer. PATIENTS & METHODS: The multicenter retrospective study was based on a review of the pre- and post-DOC clinical history, DOC treatment and outcomes. RESULTS: We reviewed the records of 123 patients (median age: 82 years) who received DOC every 3 weeks or weekly, without significant grade 3-4 toxicities. Median progression-free survival was 7 months; median overall survival from the start of DOC was 20 months, but post-progression treatments significantly prolonged overall survival. CONCLUSION: The findings of this study suggest that toxicity is acceptable, survival is independent of patient's age and survival can be significantly prolonged by the use of new agents.

Intermittent docetaxel chemotherapy as first-line treatment for metastatic castration-resistant prostate cancer patients.

AIMS: The intermittent administration of chemotherapy is a means of preserving patients' quality of life (QL). The aim of this study was to verify whether the intermittent administration of docetaxel (DOC) improves the patients' QL. PATIENTS & METHODS: All patients received DOC 70 mg/m(2) every 3 weeks for eight cycles. The patients were randomized to receive DOC continuously or with a fixed 3-month interval after the first four DOC courses. RESULTS: The study involved 148 patients. There was no difference in QL between the groups receiving intermittent or continuous treatment. Intermittence had no detrimental effects on disease control. CONCLUSION: Although feasible and not detrimental, our results showed that true intermittent chemotherapy in metastatic castration-resistant prostate cancer patients failed to improve the patients' QL.

Comparison of complications from radical cystectomy between old-old versus oldest-old patients.

INTRODUCTION: The purpose of this study was to evaluate and compare complications after radical cystectomy in patients aged ≥75 years. MATERIALS AND METHODS: 251 patients aged 75-95 years (median 79) underwent radical cystectomy between 2000 and 2012 at four institutions. The patients were divided into two groups: ≥75-84 years of age (group 1) versus ≥85 years of age (group 2). Comorbidities, body mass index, and complications were obtained retrospectively, except at the Central Hospital of Bolzano and Weill Cornell Medical Center, which collected data prospectively. Cancer-specific survival, overall mortality, hospital stay, clinical outcome and complications were assessed. Complications were categorized using the Clavien-Dindo classification reporting system. The mean follow-up was 21 months. RESULTS: The median hospital stay was 17 (2-91) days. Perioperative Clavien-Dindo grade ≥III complications were seen in 24.1% (48/199) of group 1 patients and 19.2% (10/52) of group 2 patients (p = 0.045). 30- and 90-day mortality was 4.5 and 13.5% in group 1 and 6.5 and 32.3% in group 2, respectively. Only the 90-day mortality rate was statistically significant (p < 0.05) between the two groups. The 3-year overall survival was 40% in group 1 and 34% in group 2. The 3-year cancer-specific survival was 52% in group 1 and 50% in group 2. CONCLUSIONS: We evaluated a large series of elderly (≥75 years) patients undergoing radical cystectomy at four institutions. Comparing patients aged ≥75-84 and ≥85 years revealed no significant difference in complications, 30-day mortality, overall and cancer-specific survival rates. Only 90-day mortality rates were significantly higher in the ≥85-year-old patients.

Perforation during TUR of bladder tumours influences the natural history of superficial bladder cancer.

OBJECTIVES: Bladder perforation is the second most common complication during transurethral resection of bladder tumours. It is unknown whether perforation affects the natural history of the tumour through cell seeding. The aim of this study was to study the impact of perforation on the oncologic outcomes of bladder carcinoma. MATERIALS AND METHODS: Between 2003 and 2007, 926 consecutive patients underwent transurethral resection of bladder tumours at our institution; 327 cases were staged ≥ pT2 and were treated immediately with cystectomy and/or multimodal therapy and therefore excluded from the study. An additional 34 cases without urothelial carcinoma were excluded. Of the remaining 565 patients with non-muscle invasive bladder cancer, 457 (80.8 %) were male and 108 (19.2 %) were female with a mean age of 69.5 years in men and 67.3 years in women. Thirty-seven patients (6.5 %) experienced bladder perforation at the time of tumour resection. This group of patients (Group 1) was compared to the remaining 528 patients (Group 2) who did not experience a bladder perforation. RESULTS: Patients with bladder wall perforation experienced a shorter disease-free survival in both univariate (p = 0.003) and multivariate analyses (p = 0.006). In addition, subsequent recurrences revealed stage progression of recurrent disease (p = 0.05) and trended to a higher number of cystectomies in the perforated group of patients (p = 0.06). Nevertheless, perforation did not appear to influence overall survival (p = 0.127) or cancer-specific survival (p = 0.141). CONCLUSION: The results indicate that bladder perforation during resection of superficial bladder tumours is burdened by a shortened disease-free survival and T-stage progression.

The Charlson comorbidity index predicts survival after disease recurrence in patients following radical cystectomy for urothelial carcinoma of the bladder.

OBJECTIVE: To identify prognostic clinical and histopathological parameters, including comorbidity indices at the time of radical cystectomy (RC), for overall survival (OS) after recurrence following RC for urothelial carcinoma of the bladder (UCB). MATERIALS AND METHODS: A retrospective multicenter study was carried out in 555 unselected consecutive patients who underwent RC with pelvic lymph node dissection for UCB from 2000 to 2010. A total of 227 patients with recurrence comprised our study group. Cox proportional hazards regression models were calculated with established variables to assess their independent influence on OS after recurrence. RESULTS: The median time from RC to recurrence and the median OS after recurrence was 10.9 and 5.4 months, respectively. Neither the time to recurrence nor the type of recurrence (systematic vs. local) was predictive of the OS. In contrast, age (hazard ratio (HR) 1.53, p = 0.011), lymph node metastasis (HR 1.56, p = 0.007), and positive surgical margins (HR 1.53, p = 0.046) significantly affected the OS after disease recurrence. In addition, the dichotomized Charlson comorbidity index (CCI; dichotomized into >2 vs. 0-2) was the only comorbidity score with an independent prediction of OS (HR 1.41, p = 0.033). We observed a significant gain in the base model's predictive accuracy, i.e. from 68.4 to 70.3% (p < 0.001), after inclusion of the dichotomized CCI. CONCLUSIONS: We present the first outcome study of comorbidity indices used as predictors of OS after disease recurrence in patients undergoing RC for UCB. The CCI at the time of RC had no significant influence on the time to recurrence but represented an independent predictor of OS after disease recurrence.

Recurrence and progression in patients with non-muscle invasive bladder cancer: prognostic models including multicolor fluorescence in situ hybridization molecular grading.

OBJECTIVE: To test the prognostic value of multicolor fluorescence in situ hybridization analyses of tumor cells in urine for prediction of the recurrence and progression of tumor in patients with intermediate risk non-muscle invasive bladder cancer. METHODS: A total of 168 patients with non-muscle invasive bladder cancer were included in the study. Fluorescence in situ hybridization was carried out on the bladder wash urine collected before resection. Tumors were classified as low molecular grading if they had a diploid chromosomal pattern or only a loss of p16 or ch3 aneuploidy, and as high molecular grading if they showed aneuploidy of ch7 or 17. Cox regression models assessed the added prognostic value of fluorescence in situ hybridization for primary tumor recurrence or progression, respectively. RESULTS: Median follow up was 67 months. A total of 57% of tumors were classified as low molecular grading. The 2- and 5-year recurrence-free survival was 68% and 49% for low molecular grading, and 47% and 30% for high molecular grading, respectively. The 2- and 5-year progression-free survival was 95% and 84% for low molecular grading, and 79% and 58% for high molecular grading tumor patients, respectively. Molecular grading (hazard ratio 1.60; P = 0.03) was associated with recurrence, when also accounting for histopathology and a patient's characteristics. Both cancer severity score (hazard ratio 1.51; P < 0.01) and molecular grading (hazard ratio 2.53; P < 0.01) independently and positively predicted progression in multivariable models. The C-index for predicting recurrence increased from 0.58 to 0.61 when molecular grading fluorescence in situ hybridization was included in the model, and from 0.68 to 0.72 when predicting progression. CONCLUSIONS: Fluorescence in situ hybridization-based molecular grading increases the accuracy of a prognostic model, predicting both recurrence and progression in patients with intermediate risk non-muscle invasive bladder cancer.

Salvage therapy for BCG failure with intravesical sequential gemcitabine and docetaxel in patients with recurrent NMIBC.

INTRODUCTION: Bacillus Calmette-Guérin (BCG) failure occurs in approximately 40% of patients with non-muscle-invasive bladder cancer (NMIBC) within two years. We describe our institutional experience with sequential intravesical gemcitabine and docetaxel (gem/doce) as salvage therapy post-BCG failure in patients who were not candidates for or declined radical cystectomy (RC). METHODS: We retrospectively reviewed NMIBC patients with BCG failure who received gem/doce from April 2019 through October 2022 at the CHU de Québec-Université Laval. Patients received at least five weekly intravesical instillations according to published protocols. Patients who responded to gem/doce had maintenance instillations monthly for up to two years. Primary outcome was progression-free survival (PFS). Secondary outcomes included recurrence-free survival (RFS), cystectomy-free survival (CFS), cancer-specific survival (CSS), overall survival (OS), and treatment adverse events. Survival probabilities were estimated using the Kaplan-Meier method from the first gem/doce instillation. RESULTS: Thirty-five patients with a median age of 78 years old were included in the study. The median followup time was 21 months (interquartile range 10-29). More than 25% of patients received two or more prior BCG induction treatments. Overall and MIBC PFS estimates at one year were 85% and 88%, and at two years, 60% and 70%, respectively. Adverse events occurred in 37% of the patients, but only two patients didn't complete the treatment due to intolerance. Three patients underwent RC due to cancer progression. OS was 94% at two years. CONCLUSIONS: With 60% of PFS at two years, gem/doce appears to be a safe and well-tolerated option for BCG failure patients. Further studies are needed to justify widespread use.

Intrapatient Intermetastatic Heterogeneity Determined by Triple-Tracer PET Imaging in mCRPC Patients and Correlation to Survival: The 3TMPO Cohort Study.

Intrapatient intermetastatic heterogeneity (IIH) has been demonstrated in metastatic castration-resistant prostate cancer (mCRPC) patients and is of the utmost importance for radiopharmaceutical therapy (RPT) eligibility. This study was designed to determine the prevalence of IIH and RPT eligibility in mCRPC patients through a triple-tracer PET imaging strategy. Methods: This was a multisite prospective observational study in which mCRPC patients underwent both 18F-FDG and 68Ga-prostate-specific membrane antigen (PSMA)-617 PET/CT scans. A third scan with 68Ga-DOTATATE, a potential biomarker of neuroendocrine differentiation, was performed if an 18F-FDG-positive/68Ga-PSMA-negative lesion was found. Per-tracer lesion positivity was defined as having an uptake at least 50% above that of the liver. IIH prevalence was defined as the percentage of participants having at least 2 lesions with discordant features on multitracer PET. Results: IIH was observed in 81 patients (82.7%), and at least 1 18F-FDG-positive/68Ga-PSMA-negative lesion was found in 45 patients (45.9%). Of the 37 participants who also underwent 68Ga-DOTATATE PET/CT, 6 (16.2%) had at least 1 68Ga-DOTATATE-positive lesion. In total, 12 different combinations of lesion imaging phenotypes were observed. On the basis of our prespecified criteria, 52 (53.1%) participants were determined to be eligible for PSMA RPT, but none for DOTATATE RPT. Patients with IIH had a significantly shorter median overall survival than patients without IIH (9.5 mo vs. not reached; log-rank P = 0.03; hazard ratio, 2.7; 95% CI, 1.1-6.8). Conclusion: Most mCRPC patients showed IIH, which was associated with shorter overall survival. On the basis of a triple-tracer PET approach, multiple phenotypic combinations were found. Correlation of these imaging phenotypes with genomics and treatment response will be relevant for precision medicine.

A phase IIb randomized placebo-controlled trial testing the effect of MAG-EPA long-chain omega-3 fatty acid dietary supplement on prostate cancer proliferation.

BACKGROUND: High prostate eicosapentaenoic fatty acid (EPA) levels were associated with a significant reduction of upgrading to grade group (GG) ≥ 2 prostate cancer in men under active surveillance. We aimed to evaluate the effect of MAG-EPA long-chain omega-3 fatty acid dietary supplement on prostate cancer proliferation. METHODS: A phase II double-blind randomized placebo-controlled trial was conducted in 130 men diagnosed with GG ≥ 2 prostate cancer and undergoing radical prostatectomy between 2015-2017 (Clinicaltrials.gov: NCT02333435). Participants were randomized to receive 3 g daily of either MAG-EPA (n = 65) or placebo (n = 65) for 7 weeks (range 4-10) prior to radical prostatectomy. The primary outcome was the cancer proliferation index quantified by automated image analysis of tumor nuclear Ki-67 expression using standardized prostatectomy tissue microarrays. Additional planned outcomes at surgery are reported including plasma levels of 27 inflammatory cytokines and fatty acid profiles in circulating red blood cells membranes and prostate tissue. RESULTS: Cancer proliferation index measured by Ki-67 expression was not statistically different between the intervention (3.10%) and placebo (2.85%) groups (p = 0.64). In the per protocol analyses, the adjusted estimated effect of MAG-EPA was greater but remained non-significant. Secondary outcome was the changes in plasma levels of 27 cytokines, of which only IL-7 was higher in MAG-EPA group compared to placebo (p = 0.026). Men randomized to MAG-EPA prior to surgery had four-fold higher EPA levels in prostate tissue compared to those on placebo. CONCLUSIONS: This MAG-EPA intervention did not affect the primary outcome of prostate cancer proliferation according to nuclear Ki-67 expression. More studies are needed to decipher the effects of long-chain omega-3 fatty acid dietary supplementation in men with prostate cancer.

It is thought that our diet can impact our risk of cancer and affect outcomes in patients with cancer. Omega-3 fatty acids, mostly found in fatty fish, might be beneficial by protecting against prostate cancer and its adverse outcomes. We conducted a clinical trial to test the effects of an omega-3 dietary supplement (MAG-EPA) in men with prostate cancer. We randomly allocated 130 men to receive either MAG-EPA or a placebo for 7 weeks before their prostate cancer surgery. We measured a marker of how much tumor cells were proliferating (or growing in number) at the point of surgery, which might indicate how aggressive their disease was. However, the supplement did not affect tumor cell proliferation. The supplement was therefore not beneficial in this group of patients and further studies  are needed to test and confirm the effects of MAG-EPA on prostate cancer cells.

Long-term PSA-free survival and castration-free survival with delayed antiandrogen therapy in patients with one versus two or more positive nodes at prostatectomy.

PURPOSE: To analyze time in relation to biochemical recurrence (BCR) and antiandrogen therapy (ADT) in patients with node metastasis at retropubic prostatectomy (RRP) and to identify prognostic factors of BCR- and ADT-free survival. METHODS: Positive node patients at RRP and extended pelvic lymph node dissection (ePLND) were recruited retrospectively. Neoadjuvant and adjuvant therapy were exclusion criteria. BR was defined as PSA ≥ 0.3 ng/ml or the beginning of salvage radiotherapy or, ADT. RESULTS: Between 1995 and 2008, 70 node-positive patients after RRP were followed without ADT. Overall, BCR-free survival was 77.9% at 2 years and 29.7% at 8 years. The median time to BCR was 59.2 months for patients with only one node compared to 27.7 months for those with ≥2 nodes. The number of positive nodes was the only independent predictor of BCR in Cox regression multivariable analysis. ADT-free survival was 78% at 2 years and 39% at 8 years. The median time to ADT for patients with only one positive node was 115 months, and the 5 years ADT-free survival was 68.8%. Gleason score and the number of positive nodes were the only independent prognostic factors of time to ADT in the Cox regression multivariable analysis. CONCLUSIONS: The prognosis of patients with positive nodes after RRP and ePNLD is good in terms of BCR- and ADT-free survival. After 8 years, 29.7% were still free from BCR, and 39% did not receive ADT. The number of positive nodes was the most important predictor of BCR- and ADT-free survival.

Comparison of radical cystectomy with conservative treatment in geriatric (≥80) patients with muscle-invasive bladder cancer.

INTRODUCTION: The aim of this study was to compare overall survival in elderly patients (≥ 80 years) with muscle-invasive bladder cancer (MIBC) undergoing either radical cystectomy (RC) or conservative treatment. MATERIAL AND METHODS: We performed a retrospective, comparative analysis of overall- and cancer-specific survival in octagenarians with MIBC (≥ pT2) submitted to RC or conservative treatment. Uni- and multivariable Cox regression analysis were performed to assess predictors of overall survival. Cumulative hospital stay was also analyzed for all patients. RESULTS: The RC-group consisted of 33 patients with a mean age of 82.3 years (IQR 80.4-85.4 years) and the bladder preservation a cohort of 35 patients aged 83.8 years (IQR 81.8-88.2 years). No difference was detectable for overall survival (15.9 months versus 9.5 months; p = 0.18) and cancer-specific survival (23.5 months versus 19.5 months p = 0.71) or 90-day mortality (6.1% versus 14.3%; p = 0.43) between the two groups. Patients who received conservative treatment had a shorter cumulative length of hospital stay (p = 0.001). Age at the time of transurethral resection of the bladder (TUR-B) was an independent predictor of the overall survival (p = 0.004). CONCLUSIONS: In this retrospective study, no clear survival benefit was observed for patients ≥80 years submitted either to radical cystectomy or conservative treatment. There was however a trend favoring radical cystectomy but this did not approach statistical significance. Octagenarians that underwent RC however spent more of their remaining lifetime in the hospital than those treated conservatively.

Effects of Concentrated Long-Chain Omega-3 Polyunsaturated Fatty Acid Supplementation on Quality of Life after Radical Prostatectomy: A Phase II Randomized Placebo-Controlled Trial (RCT-EPA).

Prostate cancer (PCa) and associated treatments incur symptoms that may impact patients' quality of life. Studies have shown beneficial relationships between diet, especially omega-3 fatty acids, and these symptoms. Unfortunately, only few data describing the relationship between long-chain omega-3 fatty acids (LCn3) and PCa-related symptoms in patients are available. The purpose of this study was to evaluate the effects of LCn3 supplementation on PCa-specific quality of life in 130 men treated by radical prostatectomy. Men were randomized to receive a daily dose of either 3.75 g of fish oil or a placebo starting 7 weeks before surgery and for up to one-year post-surgery. Quality of life was assessed using the validated EPIC-26 and IPSS questionnaires at randomization, at surgery, and every 3 months following surgery. Between-group differences were assessed using linear mixed models. Intention-to-treat analyses showed no significant difference between the two groups. However, at 12-month follow-up, per-protocol analyses showed a significantly greater increase in the urinary irritation function score (better urinary function) (MD = 5.5, p = 0.03) for the LCn3 group compared to placebo. These results suggest that LCn3 supplementation may improve the urinary irritation function in men with PCa treated by radical prostatectomy and support to conduct of larger-scale studies.

Effects of omega-3 supplementation on psychological symptoms in men with prostate cancer: Secondary analysis of a double-blind placebo-controlled randomized trial.

BACKGROUND: In the general population, a higher omega-3 polyunsaturated fatty acids intake is associated with lower levels of several psychological symptoms, especially depression. However, the existing evidence in cancer is equivocal. METHODS: This phase IIB double-blind, placebo-controlled trial was aimed at comparing the effects of eicosapentaenoic acid monoacylglyceride (MAG-EPA) supplementation and high oleic acid sunflower oil (HOSO; placebo) on depression levels (primary outcome) and other symptoms (anxiety, fear of cancer recurrence, fatigue, insomnia, perceived cognitive impairments; secondary outcomes). Participants, recruited in a prostate cancer clinic, were randomized to MAG-EPA (3.75 g daily; n = 65) or HOSO (3.75 g daily; n = 65) for 1 year post-radical prostatectomy (RP), starting 4-10 weeks before surgery. Patients completed self-report scales at baseline (before RP) and 3, 6, 9, and 12 months after: Hospital Anxiety and Depression Scale (HADS), Fear of Cancer Recurrence Inventory (FCRI), Insomnia Severity Index (ISI), Fatigue Symptom Inventory (FSI), and Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog). RESULTS: Analyses showed significant reductions in HADS-depression, HADS-anxiety, FCRI, ISI, FSI-number of days, and FACT-Cog-impact scores over time. A significant group-by-time interaction was obtained on FACT-Cog-Impact scores only; yet, the temporal change was significant in HOSO patients only. CONCLUSIONS: Several symptoms significantly decreased over time, mainly within the first months of the study. However, MAG-EPA did not produce greater reductions than HOSO. Omega-3 supplementation does not seem to improve psychological symptoms of men treated with RP.

Predictive capacity of four comorbidity indices estimating perioperative mortality after radical cystectomy for urothelial carcinoma of the bladder.

UNLABELLED: What's known on the subject? and What does the study add? The degree of comorbidity significantly affects the course of patients with bladder cancer undergoing radical cystectomy (RC). To our knowledge this is the first study comparing four different comorbidity indices in patients undergoing RC for urothelial carcinoma to assess the best clinical predictors for 90-day perioperative mortality. We concluded that the ASA score should be the method of choice, as it showed a predictive ability superior to that of ECOG and CCI, and is much easier to generate than the ACE-27. OBJECTIVE: To evaluate which of the following among the Adult Comorbidity Evaluation-27 (ACE-27), the Charlson Comorbidity Index (CCI), the Eastern Cooperative Oncology Group performance status (ECOG) and the American Society of Anesthesiologists (ASA) comorbidity scores correlate best with perioperative mortality after radical cystectomy (RC) for urothelial carcinoma (UC) of the bladder. PATIENTS AND METHODS: A study was carried out on 555 unselected consecutive patients without neoadjuvant chemotherapy who underwent RC for UC of the bladder from 2000 to 2010 at one of two institutions. Patients' medical records were reviewed retrospectively. We established a defined binary linear progression model based on clinical variables to predict perioperative mortality <90 days after RC (90PM). To this model we added, individually, the comorbidity indices ACE-27, CCI, ECOG, and ASA to assess their predictive capacity regarding 90PM. RESULTS: The overall 90PM was 7.9%. Age (P = 0.01) and clinical distant metastatic tumour stage (P = 0.002) were independent predictors for 90PM in the multivariate analysis. Each of the four investigated comorbidity indices was able to significantly increase the predictive capacity of the basic model: ECOG +13.5%, (odds ratio [OR]: 1.61, P = 0.036; area under the curve [AUC] 74.7), ASA Score +28.3% (OR: 2.19, P = 0.004; AUC 76.1), Charlson Index +12.3% (OR: 1.31, P = 0.047; AUC 73.8) and ACE-27 + 29.8% (OR: 1.72, P = 0.004; AUC 76.1). CONCLUSIONS: ASA and ACE-27 show a nearly identical clinical predictive value for perioperative mortality. Both scores could be considered for clinical practice. With regard to ease of generation and availability, the ASA score can be regarded as the best instrument.

Analysis of sex-based differences to Bacillus Calmette-Guérin for non-muscle invasive bladder cancer.

OBJECTIVE: To evaluate whether differences exist between men and women in response to intravesical BCG treatments. The incidence of urothelial carcinoma of the bladder is lower in women but they tend to present with more aggressive and advanced disease. Some prior studies also suggest there are sex-based differences in response to treatment for non-muscle invasive bladder tumors. METHODS: In this retrospective study, we reviewed all consecutive patients who received BCG at the CHU de Québec - Laval University from 2009-2019. Men and women were treated with intravesical BCG therapy following pathologic confirmation of urothelial carcinoma. Outcomes evaluated include recurrence, progression, and treatment tolerability. Recurrence was defined as a pathology confirmed cancer whereas progression was the new development of high-grade (recurrence) pathology or an increase of stage. Tolerability was defined according to the proportion of prescribed BCG received. All clinical details were obtained through review of the medical records, collaborated by pharmacy records for BCG administration. Competing-risk analysis was used to compare outcomes. RESULTS: Among 613 patients who received BCG at our institution between 2009-2019, 472 (77.0%) were men and 141 (23.0%) were women. The recurrence rate was not different between sexes, with a 5-year recurrence risk of 52% (95% CI: 36.93-65.4) among women compared to 57.5% (CI 95%: 51.9-62.6) among men. The overall non-progression rate at 1,3 and 5 years was 97.3% (95% CI: 95.6%-98.3%), 93.6% (95% CI: 91.2%-95.4%), and 91.7% (95% CI: 88.4%-94.1%), respectively. The completion of ≥5 induction BCG instillations and maintenance BCG use was similar in both genders. CONCLUSIONS: We report a contemporary NMIBC cohort treated with BCG and find no clear evidence for sex-based differences in response to BCG treatment in regard of progression, recurrence, and tolerability.

Opioid use after uro-oncologic surgeries in time of opioid crisis.

INTRODUCTION: Recent literature emphasizes how overprescription and lack of guidelines contribute to wide variation in opioid prescribing practices and opioid-related harms. We conducted a prospective, observational study to evaluate opioid prescriptions among uro-oncologic patients discharged following elective in-patient surgery. METHODS: Patients who underwent four surgeries were included: open retropubic radical prostatectomy, robot-assisted radical prostatectomy, laparoscopic radical nephrectomy, and laparoscopic partial nephrectomy. The primary outcome was the dose of opioids used after discharge (in oral morphine equivalents [MEq]). Secondary outcomes included: opioid requirements for 80% of the patients, management of unused opioids, opioid use three months postoperative, opioid prescription refills, and guidance about opioid disposal. RESULTS: Sixty patients were included for analysis. Patients used a mean of 30 MEq (95% confidence interval 17.8-42.2) at home and 80% of the patients used 50 MEq or less. A mean of 40.4 MEq per patient was overprescribed. Fifty percent of the patients kept the remaining opioids at home, with only 20.0% returning them to their pharmacy. After three months, 5.0% of the patients were using opioids at least occasionally. Three patients needed a new opioid prescription. Forty percent reported having received information regarding management of unused opioids. CONCLUSIONS: We found 60% of opioids prescribed were unused, with half of our patients keeping these unused tablets at home. Our results suggest appropriate opioid prescription amounts needed for urological cancer surgery, with 80% of the patients using 50 MEq or less of morphine equivalents.

Effects of omega-3 fatty acids supplementation on perioperative blood loss and complications after radical prostatectomy.

BACKGROUND AND AIMS: Many dietary supplements, including omega-3 fatty acids (ω3), are suspected to affect blood coagulation and platelet function. Despite no clinical evidence, discontinuation is recommended before radical prostatectomy. However, long-chain ω3 (LCω3) appear beneficial against prostate cancer progression. Here, we aim to determine the effect of LCω3 supplements on perioperative bleeding, hemoglobin, platelets, and postoperative complications after radical prostatectomy. METHODS: This is a planned exploratory analysis of 130 patients diagnosed with prostate cancer grade group 2 or greater enrolled in a randomized controlled trial (NCT02333435) testing the effects of LCω3, on prostate cancer biological and pathological outcomes at radical prostatectomy as main outcomes. The LCω3 intervention (MAG-EPA 3 g daily) or equivalent placebo was given 4-10 weeks prior to radical prostatectomy. An intention-to-treat analysis approach was used with bi-variate statistical testing of bleeding and complications outcomes. We also estimated the difference between groups using linear regression and non-parametric quantile regression models. All models were adjusted for confounding variables selected on clinical relevance. RESULTS: We found no clinically significant effect of LCω3 versus placebo on perioperative bleeding, laboratory tests or postoperative complications. In contrast, as expected, we found a significant increase in perioperative bleeding in open retropubic radical prostatectomy compared to robot-assisted radical prostatectomy (adjusted difference 115.8 mL, p = 0.04). CONCLUSIONS: Our results suggest that ω3 supplements can be safely taken before radical prostatectomy without increasing surgical bleeding risk. These findings are relevant since ω3 may beneficially affect prostate cancer evolution.

Perception and satisfaction of patients after telemedicine urology consultations: A matched analysis with physicians' perspective.

INTRODUCTION: During the first regional COVID-19 lockdown in March 2020, we conducted a study aimed at evaluating completeness of telemedicine consultation in urology. Of 1679 consultations, 67% were considered completely managed by phone. The aim of the present study was to assess patients' experience and satisfaction with telemedicine and to compare them with urologists' perceptions about quality and completeness of the telemedicine consultation. METHODS: We contacted a randomly selected sample of patients (n=356) from our previous study to enquire about their experience. We used a home patient experience questionnaire, inspired by the Patient Experiences Questionnaire for Out-of-Hours Care (PEQOHC) and the Consumer Assessment Health Profile Survey (CAHPS). RESULTS: Of 356 patients contacted, 315 agreed to complete the questionnaire. Urological consultations were for non-oncological (104), oncological (121), cancer suspicion (41), and pediatric (49) indications. Mean patient satisfaction score after telemedicine consultation was 8.8/10 (median 9/10) and 86.3% of patients rated the quality of the consultation as either excellent (54.6%) or very good (31.7%). Consultations regarding cancer suspicion had the lowest score (8.3/10). Overall, 46.7% of all patients would have preferred an in-person visit outside of the pandemic situation. Among patients whose consultations were rated suboptimal by urologists, almost a third more (31.2%) would have preferred an in-person visit (p=0.03). CONCLUSIONS: Despite high reported patient satisfaction rates with telemedicine, it is noteworthy that nearly half of the patients would have preferred an in-person visit. Post-pandemic, it will be important to incorporate telemedicine as an alternative, while retaining and offering in-person visits.
