RESUMEN

There is an ongoing need for biomarkers that could reliably predict the outcome of BC and that could guide the management of this disease. In this setting, we aimed to explore the prognostic value of the transcription factor P63 in patients with muscle-invasive bladder cancer (MIBC) having undergone radical cystectomy. The correlation between P63 expression and clinicopathological features (tumor stage, nodes involvement, patterns of muscularis propria invasion, papillary architecture, anaplasia, concomitant carcinoma in situ, lymphovascular invasion, perineural invasion, necrosis) and molecular subtyping (basal and luminal type tumors) was tested in 65 radical cystectomy specimens and matched with cancer-specific survival (CSS) and overall survival (OS). P63-negative tumors displayed significantly higher rates of pattern 2 of muscularis propria invasion (50% vs. 14%, p = 0.002) and variant histology (45% vs. 19%, p = 0.022) compared to P63-positive ones. According to the combined expression of CK5/6 and CK20 (Algorithm #1), P63-positive and P63-negative tumors were mostly basal-like and double-negative, respectively (p = 0.004). Using Algorithm #2, based on the combined expression of CK5/6 and GATA3, the vast majority of tumors were luminal overall and in each group (p = 0.003). There was no significant difference in CSS and OS between P63-positive and P63-negative tumors, but the former featured a trend towards longer OS. Though associated with pathological features harboring negative prognostic potential, P63 status as such failed to predict CSS and OS. That said, it may contribute to better molecular subtyping of MIBC.

RESUMEN

BACKGROUND: To examine the agreement of different calculated estimated glomerular filtration rate (eGFR) formulas and measured creatinine clearance (CrCI) at the primary diagnosis of muscle-invasive bladder cancer (MIBC). MATERIALS AND METHODS: We performed a multicenter analysis of patients with MIBC, treated with cisplatin-based neoadjuvant chemotherapy (NAC) and radical cystectomy (RC), or with RC alone, between 2011 and 2021. Baseline eGFR was computed using 4 calculated serum equations including Cockcroft-Gault (CG), MDRD, CKD-EPI 2009, and race-free CKD-EPI 2021. To examine the association between calculated eGFR and measured CrCI, subgroup analyses were performed among patients in whom measured 24-hour urine CrCl was determined. Cisplatin-ineligibility was defined as CrCI and/or eGFR < 60 mL/minute per 1.73 m2. RESULTS: Of 956 patients, 30.0%, 33.3%, 31.9%, and 27.7% were found to be cisplatin-ineligible by the CG, MDRD, CKD-EPI, and race-free CKD-EPI equations (P = .052). The concordance between calculated eGFR formulas was rated substantial (Cohen's kappa (k): 0.66-0.95). Among the subgroup (n = 245) with measured CrCl, 37 (15.1%) patients had a CrCI less than 60 mL/minute. Concordance between measured CrCl and calculated eGFR was poor (ĸ: 0.29-0.40). All calculated eGFR formulas markedly underestimated the measured CrCI. Specifically, 78%-87.5% of patients with a calculated eGFR between 40 and 59 mL/minute exhibited a measured CrCI ≥ 60 mL/minute. CONCLUSIONS: Comparing calculated eGFR formulas, similar percentages of patients with MIBC were deemed cisplatin-ineligible. However, a significant number of patients could be upgraded by being cisplatin-fit based on measured CrCI, particularly when the calculated eGFR was falling within the gray range of 40-59 mL/minute.

RESUMEN

PURPOSE: The purpose of this American Urological Association (AUA)/Society of Urologic Oncology (SUO) guideline amendment is to provide a useful reference on the effective evidence-based treatment strategies for non-muscle invasive bladder cancer (NMIBC). MATERIALS AND METHODS: In 2023, the NMIBC guideline was updated through the AUA amendment process in which newly published literature is reviewed and integrated into previously published guidelines in an effort to maintain currency. The amendment allowed for the incorporation of additional literature released since the previous 2020 amendment. The updated search gathered literature from July 2019 to May 2023. This review identified 1918 abstracts, of which 75 met inclusion criteria.When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) in support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions. RESULTS: Updates were made to statements on variant histologies, urine markers after diagnosis of bladder cancer, intravesical therapy, BCG maintenance, enhanced cystoscopy, and future directions. Further revisions were made to the methodology and reference sections as appropriate. CONCLUSIONS: This guideline seeks to improve clinicians' ability to evaluate and treat patients with NMIBC based on currently available evidence. Future studies will be essential to further support or refine these statements to improve patient care.

RESUMEN

PURPOSE: Although representing approximately 25% of patients diagnosed with bladder cancer, muscle-invasive bladder cancer (MIBC) carries a significant risk of death that has not significantly changed in decades. Increasingly, clinicians and patients recognize the importance of multidisciplinary collaborative efforts that take into account survival and quality of life concerns. This guideline provides a risk-stratified, clinical framework for the management of muscle-invasive urothelial bladder cancer. METHODOLOGY/METHODS: In 2024, the MIBC guideline was updated through the AUA amendment process in which newly published literature is reviewed and integrated into previously published guidelines in an effort to maintain currency. The amendment allowed for the incorporation of additional literature released since the previous 2020 amendment. The updated search gathered literature from May 2020 to November 2023. This review identified 3739 abstracts, of which 46 met inclusion criteria.When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions. RESULTS: Updates were made regarding neoadjuvant/adjuvant chemotherapy, radical cystectomy, pelvic lymphadenectomy, multi-modal bladder preserving therapy, and future directions. Further revisions were made to the methodology and reference sections as appropriate. CONCLUSIONS: This guideline seeks to improve clinicians' ability to evaluate and treat patients with MIBC based on currently available evidence. Future studies will be essential to further support or refine these statements to improve patient care.

RESUMEN

PURPOSE: We assessed the effect of prophylactic biologic mesh on parastomal hernia (PSH) development in patients undergoing cystectomy and ileal conduit (IC). MATERIALS AND METHODS: This phase 3, randomized, controlled trial (NCT02439060) included 146 patients who underwent cystectomy and IC at the University of Southern California between 2015 and 2021. Follow-ups were physical exam and CT every 4 to 6 months up to 2 years. Patients were randomized 1:1 to receive FlexHD prophylactic biological mesh using sublay intraperitoneal technique vs standard IC. The primary end point was time to radiological PSH, and secondary outcomes included clinical PSH with/without surgical intervention and mesh-related complications. RESULTS: The 2 arms were similar in terms of baseline clinical features. All surgeries and mesh placements were performed without any intraoperative complications. Median operative time was 31 minutes longer in patients who received mesh, yet with no statistically significant difference (363 vs 332 minutes, P = .16). With a median follow-up of 24 months, radiological and clinical PSHs were detected in 37 (18 mesh recipients vs 19 controls) and 16 (8 subjects in both arms) patients, with a median time to radiological and clinical PSH of 8.3 and 15.5 months, respectively. No definite mesh-related adverse events were reported. Five patients (3 in the mesh and 2 in the control arm) required surgical PSH repair. Radiological PSH-free survival rates in the mesh and control groups were 74% vs 75% at 1 year and 69% vs 62% at 2 years. CONCLUSIONS: Implementation of biologic mesh at the time of IC construction is safe without significant protective effects within 2 years following surgery.

RESUMEN

PURPOSE: Postoperative education and symptom tracking are essential following cystectomy to reduce readmission rates and information overload. To address these issues, an internet-based tool was developed to provide education, alerts, and symptom tracking. We aimed to evaluate the tool's feasibility, acceptability, and impact on complication and readmission rates. MATERIALS AND METHODS: Thirty-three eligible patients over 18 years old scheduled for cystectomy were enrolled. Patients were asked to use the mobile health (mHealth) tool daily for the first 2 weeks, then less frequently up to 90 days after discharge. Descriptive statistics were used to summarize study variables. Feasibility was defined as at least 50% of patients using the tool once a week, and acceptability as patient satisfaction of > 75%. RESULTS: Use of the mHealth tool was feasible, with 90% of patients using it 1 week after discharge, but engagement declined over time to 50%, with technological difficulties being the main reason for nonengagement. Patient and provider acceptability was high, with satisfaction > 90%. Within 90 days, 36% experienced complications after discharge and 30% were readmitted. Engagement with the mHealth application varied but was not statistically associated with readmission (P = .21). CONCLUSIONS: The study showed that the electronic mobile health intervention for patients undergoing cystectomy was feasible, acceptable, and provided valuable educational content and symptom management. Future larger studies are needed to determine the tool's effectiveness in improving patient outcomes and its potential implementation into routine clinical care.

RESUMEN

PURPOSE: Patients treated with radical cystectomy experience a high rate of postoperative complications and frequent hospital readmissions. We sought to explore the utility of the Care Assessment Needs (CAN) score, derived from electronic health data, to estimate the risk of these adverse clinical outcomes, thereby aiding patient counseling and informed treatment decision-making. MATERIALS AND METHODS: We retrospectively examined data from 982 bladder cancer patients who underwent radical cystectomy between 2013 to 2018 within the national Veterans Health Administration system. We tested for associations between the preoperative CAN score and length of stay, discharge location, and readmission rates. RESULTS: We observed a correlation between higher CAN scores and longer hospital stays (adjusted relative risk = 1.03 [95% CI: 1.02-1.05]). An increased CAN score was also linked to greater odds of discharge to a skilled nursing facility or death (adjusted odds ratio = 1.16 [95% CI: 1.06-1.26]). Furthermore, the score was associated with hospital readmission at both 30 and 90 days post-discharge (adjusted hazard ratio = 1.03 [95% CI: 1.00-1.07] and 1.04 [95% CI: 1.00-1.07], respectively). CONCLUSIONS: The CAN score is associated with the length of hospital stay, discharge to a skilled nursing facility, and readmission within 30 and 90 days following radical cystectomy. These findings highlight the potential of healthcare systems leveraging electronic health records for automatically calculating multi-dimensional tools, like the CAN score, to identify patients at risk of adverse clinical outcomes following radical cystectomy.

RESUMEN

BACKGROUND: Systemic and local recurrences of urothelial bladder cancer (UBC) significantly impair survival after radical cystectomy (RC), but little is known about the impact of the recurrence of urothelial cancer in the upper urinary tract (UTUC). This report describes survival outcomes and their predictors for patients who underwent RC followed by radical nephroureterectomy (RNU) for UTUC. METHODS: The Surveillance, Epidemiology, and End Results database was queried to identify patients who underwent RC for UBC and subsequent RNU for UTUC. The Kaplan-Meier method and competing-risk Cox regression (CRR) were used for the survival analysis. RESULTS: Overall, 102 patients have undergone RNU within a median of 49 months (interquartile range [IQR], 27-76 months) since RC. Muscle-invasive UTUCs were predominant at RNU (n = 58; 56.7%), but organ-confined bladder tumors were most frequent at RC (n = 42, 41.5%). After RNU, the estimated 5-year overall survival (OS) was 25.9%, the cancer-specific survival (CSS) was 35.6%, the median OS was 23 months (IQR, 11-63 months), and the CSS was 34 months (IQR, 13-132 months). In the multivariable CRR, the factors predictive for CSS after RNU included male gender (hazard ratio [HR], 2.36; 95% confidence interval [CI], 1.03-5.42; p < 0.05), muscle-invasive UTUC (HR, 2.20; 95% CI, 1.13-4.28; p < 0.05), and the presence of distant metastasis (HR,11.59; 95% CI, 5.33-25.2; p < 0.001). CONCLUSIONS: In conclusion, the patients who underwent RNU for UTUC after RC for UBC experienced poor OS and CSS. The majority of RNUs were performed for locally advanced tumors. The independent risk factors for worse OS and CSS after RNU were UTUC T stage, presence of metastasis, and male gender.

RESUMEN

PURPOSE: Robot-assisted radical cystectomy (RARC) has gained traction in the management of muscle invasive bladder cancer. Urinary diversion for RARC was achieved with orthotopic neobladder and ileal conduit. Evidence on the optimal method of urinary diversion was limited. Long-term outcomes were not reported before. This study was designed to compare the perioperative and oncological outcomes of ileal conduit versus orthotopic neobladder cases of nonmetastatic bladder cancer treated with RARC. PATIENTS AND METHODS: The Asian RARC consortium was a multicenter registry involving nine Asian centers. Consecutive patients receiving RARC were included. Cases were divided into the ileal conduit and neobladder groups. Background characteristics, operative details, perioperative outcomes, recurrence information, and survival outcomes were reviewed and compared. Primary outcomes include disease-free and overall survival. Secondary outcomes were perioperative results. Multivariate regression analyses were performed. RESULTS: From 2007 to 2020, 521 patients who underwent radical cystectomy were analyzed. Overall, 314 (60.3%) had ileal conduit and 207 (39.7%) had neobladder. The use of neobladder was found to be protective in terms of disease-free survival [Hazard ratio (HR) = 0.870, p = 0.037] and overall survival (HR = 0.670, p = 0.044) compared with ileal conduit. The difference became statistically nonsignificant after being adjusted in multivariate cox-regression analysis. Moreover, neobladder reconstruction was not associated with increased blood loss, nor additional risk of major complications. CONCLUSIONS: Orthotopic neobladder urinary diversion is not inferior to ileal conduit in terms of perioperative safety profile and long-term oncological outcomes. Further prospective studies are warranted for further investigation.

RESUMEN

BACKGROUND: Currently, there is no dedicated tool to record the early outcomes of robot-assisted radical cystectomy (RARC), and existing criteria for longer-term outcomes require a minimum of 3 months for assessment. However, early evaluation is essential to prevent future morbidity and mortality, especially in surgeries with a high risk of complications in the short term. We propose a comprehensive approach to report early RARC outcomes and investigate the influence of surgeon experience on these results. PATIENTS AND METHODS: We retrospectively analyzed the outcomes of patients who underwent RARC for bladder cancer between April 2009 and April 2020. The cohort was divided chronologically into three groups: patients 1-60 in group 1, 61-120 in group 2, and 121-192 in group 3. Patients with yields of ≥ 16 lymph nodes (LN), negative soft tissue surgical margins, absence of transfusion, and absence of major complications at 30 days were regarded as attaining the RARC tetrafecta. RESULTS: Of the 192 included patients, 93 (48.4%) achieved RARC tetrafecta, with the proportion increasing with surgical experience from 41.7% in group 1 to 55.6% in group 3. Age [odds ratio (OR) 0.947; 95% confidence interval (CI) 0.924-0.970; P = 0.021], LN yield (OR 1.432; 95% CI 1.139-1.867; P = 0.001), and greater surgical experience with RARC (> 120 patients; OR 2.740; 95% CI 1.231-6.100; P = 0.014) were significantly associated with the achievement of RARC tetrafecta. CONCLUSIONS: RARC tetrafecta could be a comprehensive method for reporting early outcomes in patients undergoing RARC, with improvements aligned with the surgeon's experience.

RESUMEN

BACKGROUND: To develop a prognostic model to manage patients with muscle-invasive bladder cancer (MIBC) undergoing radical cystectomy (RC) and chemotherapy. PATIENTS AND METHODS: Clinicopathologic characteristics and survival data were collated from a North American database to develop a model. Genomic and clinicopathologic data were also obtained from European and Asian databases to externally validate the model. Patients were classified as either "primary" or "progressive" MIBC according to non-muscle invasive stage history. Optimized cancer-specific survival (CSS) models, based on MIBC types, were constructed using Cox's proportional hazard regression. Differences of biological function and tumor immunity, between two risk-based groups stratified according to the prognostic model, were estimated. RESULTS: There were 2631 participants in the American cohort, 291 in the European cohort and 142 in the Asian cohort. Under Cox's regression analysis, tumor stage, lymph node stage, age, ethnicity, and MIBC types were independent CSS predictors (all p < 0.05). The constructed nomogram, which integrated these variables, improved the predictive power. This model had good discrimination and calibration. Patients were categorized into high- or low-risk groups according to the total points calculated. Kaplan-Meier curves revealed that patients in the high-risk group had poorer survival (p < 0.001). This was confirmed with two external validation cohorts (both with p < 0.001). Higher stromal scores and increased M0 and M2 macrophage numbers were observed in samples from the high-risk group, whereas regulatory T cells had lower infiltration in these populations (all with p < 0.05). CONCLUSIONS: This MIBC type-based nomogram provides accurate CSS predictions, which could help improve patient management and clinical decision-making.

RESUMEN

BACKGROUND: Analysis of temporal trends of urinary diversion (UD) and identification of predictive factors for continent urinary diversion (CUD) in patients with bladder cancer (BC) is scarce and data on large cohorts are missing. We aimed to describe longitudinal temporal trends and predictive factors for UD among patients with BC receiving radical cystectomy (RC). PATIENTS AND METHODS: We retrospectively analysed institutional data collected from patients undergoing RC from 1986 to 2022 to describe changes in patients' characteristics and UD. Primary end points were patients' characteristics associated with type of UD. Logistic regression analysis was used to determine predictive factors for CUD. RESULTS: In total, 2224 patients (77.16% male, 22.84% female) with a mean age of 66 years [standard deviation (SD), 10.64 years] were included. We observed an increase in mean age from 59.86 (10.8) years (1986-1990) to 69.85 (9.99) years (2016-2022) (p < 0.001). The proportion of CUD gradually declined from 43.72% (94/215; 1986-1990) to 18.38% (86/468; 2016-2022). Patients who were male [odds ratio (OR): 1.92, 95% confidence interval (CI): 1.43-2.57, p < 0.001), younger (OR: 0.88, 95% CI: 0.87-0.89, p < 0.001) and had no hydronephrosis prior to RC (OR: 2.2, 95% CI: 1.66-2.92, p < 0.001) were more likely to receive CUD. CONCLUSIONS: We report the largest European single-center cohort of UD after RC, demonstrating a significant shift from CUD to IUD, accompanied by an increasing age. Finally, our data mirrors the development and extensive experience with the Mainz Pouch-I in the 1980's and 1990's together with other colon pouches.

RESUMEN

INTRODUCTION: [68 Ga]Ga-FAPI-46 PET/CT is a novel hybrid imaging method that previously showed additional diagnostic value in the assessment of distant urothelial carcinoma lesions. We hypothesized that patients with bladder cancer benefit from [68 Ga]Ga-FAPI-46 PET/CT prior to radical cystectomy for locoregional lymph node staging. MATERIALS AND METHODS: Eighteen patients underwent [68 Ga]Ga-FAPI-46 PET/CT for evaluation of lymph node (LN) status in predefined LN regions. Two hundred twenty-nine intraoperatively removed LN served as histopathological reference standard. RESULTS: Urothelial carcinoma (UC) spread was found in ten LN in seven different regions (14.3%). Hereby, [68 Ga]Ga-FAPI-46 PET/CT was positive in four out of seven regions (57.1%) and showed significantly increased FAPI uptake compared to non-pathological regions. In the remaining three out of seven (42.9%) regions, [68 Ga]Ga-FAPI-46 PET/CT was rated negative since no pathological increased FAPI uptake was detected or the proximity of the urinary tract prevented a differentiation from physiological uptake. CT was inconspicuous in these three regions. In total, two FAP-positive LN regions were found without histopathological counterpart. Overall, sensitivity, specificity, positive predictive value, and negative predictive value were 57.1%, 95.2%, 66.7%, and 93.0% for PET imaging. CONCLUSION: In summary, this innovative [68 Ga]Ga-FAPI-46 PET/CT method showed high specificity and negative predictive value in patients with bladder UC with a future potential to optimize therapy planning.

RESUMEN

This study was designed to evaluate the safety and feasibility of laparoscopic radical cystectomy (LRC) for male octogenarian patients with muscle-invasive bladder cancer (MIBC). Briefly, a total of 57 male octogenarian patients (A group) with bladder carcinoma were enrolled and underwent LRC and intracorporeal pelvic lymph node dissection with bilateral cutaneous ureterostomy from May 2016 to December 2022. Besides, 63 male patients (age < 80 years old) with bladder carcinoma undergoing LRC and 17 octogenarian male patients with bladder carcinoma undergoing open radical cystectomy (ORC) were enrolled in B and C groups as control. All perioperative clinical materials and outcomes of long-term follow-up, and complication were collected. The specific results were shown as follows. Compared with C group, the operation time and resected lymph node in A group was increased, and the estimated blood loss, the number of transfusion needed, duration of pelvic drainage and hospital stay after surgery was decreased. The death rate and ileus complication rate were higher in A group (12 cases) than in C group (15 cases). The cases of ureteral stricture in A group (13 cases) was decreased compared with that in C group. Overall, LRC and bilateral cutaneous ureterostomy are safe, feasible and better choices for the treatment of male octogenarian patients with MIBC. The octogenarian receiving cutaneous ureterostomy heals slowly and exists certain incomplete intestinal obstruction after surgery.

RESUMEN

PURPOSE: To present the widely unknown perioperative outcomes and continence status of bladder cancer patients following robotic-assisted radical cystectomy (RARC) with Mainz pouch II urinary diversion (UD). MATERIALS AND METHODS: From November 2020 to December 2023, 37 bladder cancer patients who underwent RARC with Mainz pouch II UD were retrospectively assessed (ChiCTR2300070279). The results, which included patient demographics, perioperative data, continence, and complications (early ≤ 30 days and late ≤ 30 days) were reported using the RC-pentafecta criteria. RC-pentafecta criteria included ≥ 16 lymph nodes removed, negative soft tissue surgical margins, absence of major (Grade III-IV) complication at 90 days, absence of clinical recurrence at ≤ 12 months, and absence of long-term UD-related sequelae. A numeric rating scale assessed patient satisfaction with urinary continence 30 days after surgery. The validated Patient Assessment of Constipation Symptoms (PAC-SYM) questionnaire was used to evaluate bowel function. The Kaplan-Meier curve was used to evaluate overall survival (OS). RESULTS: Of the 37 patients evaluated over a median (range) follow-up period of 23.0 (12.0-36.5) months. The median (range) age was 65 (40-81) years. The median (range) time to urinary continence after surgery was 2.3 (1.5-6) months. Of the 37 patients, 31 (83.8%) were continent both during the day and at night, 34 (91.9%) were continent during the day, 32 (86.5%) were continent at night, 35 (94.6%) were satisfied with their urinary continence status, and 21 (56.8%) were very satisfied. The mean (range) voiding frequency was 6 (4-10) during the day and 3 (2-5.5) at night. The mean (range) PAC-SYM total score was 9.50 (4.00-15.00). In 12 (32.4%) of the patients, RC-pentafecta was achieved, and achieving RC-pentafecta was linked to better satisfaction scores (7.3 vs. 5.5, p = 0.034). There was no significant difference between RC-pentafecta and No RC-pentafecta groups in terms of OS (25.6 vs. 21.5 months, p = 0.16). 7 (19.4%) patients experienced late complications. CONCLUSIONS: Mainz pouch II UD following RARC in bladder cancer patients results in a satisfactory continence rate. Achieving RC-pentafecta was correlated with better satisfaction scores. The intracorporeal approach to Mainz pouch II UD is beneficial for female patients due to its reduced invasiveness.

RESUMEN

BACKGROUND: This study aims to explore the priorities and counselling needs of patients with muscle-invasive bladder cancer faced with a decision between radical cystectomy and trimodality therapy. METHODS: We performed a qualitative study according to the phenomenological approach. Sixteen muscle-invasive bladder cancer survivors who underwent radical cystectomy or trimodality therapy completed a semi-structured interview between May 2022 and February 2023. Patients were recruited via Ghent University Hospital and a patient organisation. Data were analysed with inductive thematic analysis by a multi-disciplinary team using an iterative approach and investigators' triangulation. RESULTS: Four main priorities determining the treatment decision were identified. (1) curing the disease; (2) health-related quality of life (physical, mental and social); (3) confidence in the treatment, which was mainly based on trust in the clinician; and (4) personal attributes. Trust in the clinician can be achieved by fulfilling the patient's information needs (accurate, complete, clear, impartial, personalised, realistic, and transparent information), ensuring accessibility of the clinician, and creating a clear and personalised treatment plan, involving patients to the extend they desire. Many patients considered a patient decision aid as a valuable asset in this process. CONCLUSION: Priorities vary between patients with muscle-invasive bladder cancer. Identifying individual priorities and offering personalised information about them is crucial for ensuring trust in the clinician and confidence in the treatment. Use of a patient decision aid can be beneficial in this process.

RESUMEN

RESEARCH QUESTION: What is the relationship between antral follicle count (AFC) and chronological age, and what are the expected values for AFC? DESIGN: This was a retrospective cohort study at a specialist gynaecological ultrasound centre in London, UK. Women presenting to a gynaecology diagnostic unit for investigation of symptoms or routine check-up, and undergoing transvaginal ultrasound (TVUS) examinations, between 1 January 2017 and 22 September 2022 were included in this study. RESULTS: In total, 8821 TVUS records from 7573 patients were analysed. The relationship between AFC and age was estimated to develop an AFC nomogram independent of the stage in the menstrual cycle. AFC corresponding to the 10th, 25th, 50th, 75th and 90th centiles for each patient and age group were calculated. Both nomogram and condition-specific populations displayed a Gaussian relationship between AFC and age. For the nomogram population (scans n = 4256, patients n = 3821), a peak median AFC of 30 was observed between 21-23 years of age. The AFC distribution of the group with previous ovarian cystectomy (scans n = 534, patients n = 443) was found to be significantly different compared with the nomogram population (P < 0.0001). However, the same did not hold true for those on hormonal contraception (scans n = 566, patients n = 534) (P = 0.43). CONCLUSIONS: An AFC nomogram reporting median and interquartile values for AFC by chronological age across the reproductive years was developed. This is a useful tool for providing counselling for those undergoing ovarian reserve assessments, and can be taken any time in the menstrual cycle, including in women on hormonal contraceptives or who have undergone previous ovarian cystectomy.

RESUMEN

OBJECTIVES: To determine and summarize the available data on urinary, sexual, and health-related quality-of-life (HRQOL) outcomes after traditional radical cystectomy (RC), reproductive organ-preserving RC (ROPRC) and nerve-sparing RC (NSRC) for bladder cancer (BCa) in female patients. METHODS: The PubMed, SCOPUS and Web of Science databases were searched to identify studies reporting functional outcomes in female patients undergoing RC and urinary diversion for the treatment of BCa. The outcomes of interest were voiding function (for orthotopic neobladder [ONB]), sexual function and HRQOL. The following independent variables were derived and included in the meta-analysis: pooled rate of daytime and nighttime continence/incontinence, and intermittent self-catheterization (ISC) rates. Analyses were performed separately for traditional, organ- and/or nerve-sparing surgical approaches. RESULTS: Fifty-three studies comprising 2740 female patients (1201 traditional RC and 1539 organ-/nerve-sparing RC, and 264 nerve-sparing-alone RC) were eligible for qualitative synthesis; 44 studies comprising 2418 female patients were included in the quantitative synthesis. In women with ONB diversion, the pooled rates of daytime continence after traditional RC, ROPRC and NSRC were 75.2%, 79.3% and 71.2%, respectively. The pooled rate of nighttime continence after traditional RC was 59.5%; this rate increased to 70.7% and 71.7% in women who underwent ROPRC and NSRC, respectively. The pooled rate of ISC after traditional RC with ONB diversion in female patients was 27.6% and decreased to 20.6% and 16.8% in patients undergoing ROPRC and NSRC, respectively. The use of different definitions and questionnaires in the assessment of postoperative sexual and HRQOL outcomes did not allow a systematic comparison. CONCLUSIONS: Female organ- and nerve-sparing surgical approaches during RC seem to result in improved voiding function. There is a significant need for well-designed studies exploring sexual and HRQOL outcomes to establish evidence-based management strategies to support a shared decision-making process tailored towards patient expectations and satisfaction. Understanding expected functional, sexual and quality-of-life outcomes is necessary to allow individualized pre- and postoperative counselling and care delivery in female patients planned to undergo RC.

RESUMEN

OBJECTIVE: To compare perioperative morbidity, functional and quality-of-life (QoL) outcomes in patients with partial cystectomy vs radical cystectomy as part of pelvic exenteration. PATIENTS AND METHODS: Retrospective analysis of a prospectively maintained database of pelvic exenteration patients (1998-2021) was conducted in a single centre. Study outcomes included postoperative complications, quality-of-life, functional and stoma-related outcomes. The 36-item Short-Form Health Survey Physical and Mental Health Components, Functional Assessment of Cancer Therapy-Colorectal questionnaires and Distress Thermometer were available pre- and postoperatively. QoL outcomes were compared at the various time points. Stoma embarrassment and care scores were compared between patients with a colostomy, urostomy, and both. RESULTS: Urological complications were similar between both groups, but patients with partial cystectomy experienced less wound-related complications. Overall, 34/81 (42%) partial cystectomy patients reported one or more long-term voiding complication (i.e., incontinence [17 patients], frequency [six], retention [three], high post-voiding residuals [10], permanent suprapubic catheter/indwelling catheter [14], recurrent urinary tract infection [nine], percutaneous nephrostomy [three], progression to urostomy [three]). The QoL improved following surgery in both the partial and radical cystectomy groups, differences between cohorts were not significant. Patients with two stomas reported higher embarrassment scores than patients with one stoma, although this did not result in more difficulties in stoma care. CONCLUSIONS: Partial cystectomy patients have fewer postoperative wound-related complications than radical cystectomy patients, but often experience long-term voiding issues. The QoL outcomes are similar for both cohorts, with significant improvement following surgery.

RESUMEN

OBJECTIVES: To evaluate the impact of incorporating neoadjuvant chemotherapy (NAC) into the 'quadrifecta' outcomes composite for reporting outcomes of radical cystectomy (RC) creating a pentafecta score. PATIENTS AND METHODS: This is a retrospective multicentre analysis of patients treated with RC, with or without NAC, for bladder cancer between 2002 and 2023. The primary outcome was the effect of adding NAC to a quadrifecta outcomes composite on cancer-specific (CSS) and overall survival (OS). The quadrifecta outcomes composite included a yield of ≥16 lymph nodes, negative soft tissue surgical margin, absence of major complication within 30 days from surgery, and no delay in RC. RESULTS: A total of 590 patients were included in the analyses. A total of 233 (39.5%) patients achieved all quadrifecta outcomes and 82 (13.9%) patients were additionally treated with NAC, achieving the pentafecta. Achieving the quadrifecta outcomes composite was significantly associated with better CSS (hazard ratio [HR] 0.49, 95% confidence interval [CI] 0.32-0.75; P = 0.001) and OS (HR 0.48, 95% CI 0.34-0.69; P < 0.01). The addition of NAC to the quadrifecta composite outcomes significantly improved the discrimination of patients more likely to have better CSS (HR 0.21, 95% CI 0.08-0.57; P = 0.002) and OS (HR 0.26, 95% CI 0.12-0.55; P < 0.01). CONCLUSION: We propose a new pentafecta that may serve as a tool for standardising outcomes reporting and measuring the quality of RC.
