PURPOSE: A re-transurethral resection of the bladder (re-TURB) is a well-established approach in managing non-muscle invasive bladder cancer (NMIBC) for various reasons: repeat-TURB is recommended for a macroscopically incomplete initial resection, restaging-TURB is required if the first resection was macroscopically complete but contained no detrusor muscle (DM) and second-TURB is advised for all completely resected T1-tumors with DM in the resection specimen. This study assessed the long-term outcomes after repeat-, second-, and restaging-TURB in T1-NMIBC patients. METHODS: Individual patient data with tumor characteristics of 1660 primary T1-patients (muscle-invasion at re-TURB omitted) diagnosed from 1990 to 2018 in 17 hospitals were analyzed. Time to recurrence, progression, death due to bladder cancer (BC), and all causes (OS) were visualized with cumulative incidence functions and analyzed by log-rank tests and multivariable Cox-regression models stratified by institution. RESULTS: Median follow-up was 45.3 (IQR 22.7-81.1) months. There were no differences in time to recurrence, progression, or OS between patients undergoing restaging (135 patients), second (644 patients), or repeat-TURB (84 patients), nor between patients who did or who did not undergo second or restaging-TURB. However, patients who underwent repeat-TURB had a shorter time to BC death compared to those who had second- or restaging-TURB (multivariable HR 3.58, P = 0.004). CONCLUSION: Prognosis did not significantly differ between patients who underwent restaging- or second-TURB. However, a worse prognosis in terms of death due to bladder cancer was found in patients who underwent repeat-TURB compared to second-TURB and restaging-TURB, highlighting the importance of separately evaluating different indications for re-TURB.

BACKGROUND AND OBJECTIVE: There are limited data on real-world outcomes for patients with advanced or metastatic urothelial cancer (mUC) since immune checkpoint inhibitors (ICIs) became available. Our objective was to analyze outcomes for patients with mUC since ICIs became available. METHODS: We performed a retrospective analysis of 131 patients with mUC attending the outpatient clinic of a single tertiary care center who received systemic therapy between June 2017 and July 2021 with follow-up up to December 2022. Summary and descriptive statistics were calculated for categorical and continuous variables. The Kaplan-Meier method was applied to calculate survival, and a Cox proportional-hazards model was used to explore associations between clinical variables and outcomes. KEY FINDINGS AND LIMITATIONS: The median patient age was 68 yr (range 35-90). The first systemic therapy administered was platinum-based in 79% of cases and ICI-based in 21%. Some 61% of the cohort received a second systemic treatment, with 75% of these an ICI. Median overall survival for the entire cohort was 24 mo (interquartile range 9-35). Patients on ICI therapy for ≥6 mo had median overall survival of 59 mo (95% confidence interval 39 mo-not reached). Metastatic sites on initiation of ICI therapy and C-reactive protein kinetics were prognostic in patients receiving ICIs. Limitations include the retrospective design and inherent selection bias. CONCLUSIONS AND CLINICAL IMPLICATIONS: More than 60% of patients with mUC received second-line treatment, and 75% of these received an ICI. Patients staying on immunotherapy for more than 6 mo have substantially better outcomes in comparison to patients with less time on immunotherapy and historical cohorts. PATIENT SUMMARY: We looked at the lines of therapy and outcomes for patients with advanced or metastatic cancer of the urinary tract, starting from when immunotherapy drugs called immune checkpoint inhibitors (ICIs) became available. We found that 60% of patients have received second-line therapy, which is a double the rate in comparison to historical groups of patients. Patients with long-term ICI therapy (>6 months) had significantly better outcomes, with a median survival of more than 3 years.

BACKGROUND: Ta grade 3 (G3) non-muscle-invasive bladder cancer (NMIBC) is a relatively rare diagnosis with an ambiguous character owing to the presence of an aggressive G3 component together with the lower malignant potential of the Ta component. The European Association of Urology (EAU) NMIBC guidelines recently changed the risk stratification for Ta G3 from high risk to intermediate, high, or very high risk. However, prognostic studies on Ta G3 carcinomas are limited and inconclusive. OBJECTIVE: To evaluate the prognostic value of categorizing Ta G3 compared to Ta G2 and T1 G3 carcinomas. DESIGN, SETTING, AND PARTICIPANTS: Individual patient data for 5170 primary Ta-T1 bladder tumors from 17 hospitals were analyzed. Transurethral resection of the tumor was performed between 1990 and 2018. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Time to recurrence and time to progression were analyzed using cumulative incidence functions, log-rank tests, and multivariable Cox-regression models with interaction terms stratified by institution. RESULTS AND LIMITATIONS: Ta G3 represented 7.5% (387/5170) of Ta-T1 carcinomas of which 42% were classified as intermediate risk. Time to recurrence did not differ between Ta G3 and Ta G2 (p = 0.9) or T1 G3 (p = 0.4). Progression at 5 yr occurred for 3.6% (95% confidence interval [CI] 2.7-4.8%) of Ta G2, 13% (95% CI 9.3-17%) of Ta G3, and 20% (95% CI 17-23%) of T1 G3 carcinomas. Time to progression for Ta G3 was shorter than for Ta G2 (p < 0.001) and longer than for T1 G3 (p = 0.002). Patients with Ta G3 NMIBC with concomitant carcinoma in situ (CIS) had worse prognosis and a similar time to progression as for patients with T1 G3 NMIBC with CIS (p = 0.5). Multivariable analyses for recurrence and progression showed similar results. CONCLUSIONS: The prognosis of Ta G3 tumors in terms of progression appears to be in between that of Ta G2 and T1 G3. However, patients with Ta G3 NMIBC with concomitant CIS have worse prognosis that is comparable to that of T1 G3 with CIS. Our results support the recent EAU NMIBC guideline changes for more refined risk stratification of Ta G3 tumors because many of these patients have better prognosis than previously thought. PATIENT SUMMARY: We used data from 17 centers in Europe and Canada to assess the prognosis for patients with stage Ta grade 3 (G3) non-muscle-invasive bladder cancer (NMIBC). Time to cancer progression for Ta G3 cancer differed from both Ta G2 and T1 G3 tumors. Our results support the recent change in the European Association of Urology guidelines for more refined risk stratification of Ta G3 NMIBC because many patients with this tumor have better prognosis than previously thought.

BACKGROUND: The pathological existence and clinical consequence of stage T1 grade 1 (T1G1) bladder cancer are the subject of debate. Even though the diagnosis of T1G1 is controversial, several reports have consistently found a prevalence of 2-6% G1 in their T1 series. However, it remains unclear if T1G1 carcinomas have added value as a separate category to predict prognosis within the non-muscle-invasive bladder cancer (NMIBC) spectrum. OBJECTIVE: To evaluate the prognostic value of T1G1 carcinomas compared to TaG1 and T1G2 carcinomas within the NMIBC spectrum. DESIGN, SETTING, AND PARTICIPANTS: Individual patient data for 5170 primary Ta and T1 bladder tumors from 17 hospitals in Europe and Canada were analyzed. Transurethral resection (TUR) was performed between 1990 and 2018. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Time to recurrence and progression were analyzed using cumulative incidence functions, log-rank tests, and multivariable Cox regression models stratified by institution. RESULTS AND LIMITATIONS: T1G1 represented 1.9% (99/5170) of all carcinomas and 5.3% (99/1859) of T1 carcinomas. According to primary TUR dates, the proportion of T1G1 varied between 0.9% and 3.5% per year, with similar percentages in the early and later calendar years. We found no difference in time to recurrence between T1G1 and TaG1 (p = 0.91) or between T1G1 and T1G2 (p = 0.30). Time to progression significantly differed between TaG1 and T1G1 (p < 0.001) but not between T1G1 and T1G2 (p = 0.30). Multivariable analyses for recurrence and progression showed similar results. CONCLUSIONS: The relative prevalence of T1G1 diagnosis was low and remained constant over the past three decades. Time to recurrence of T1G1 NMIBC was comparable to that for other stage/grade NMIBC combinations. Time to progression of T1G1 NMIBC was comparable to that for T1G2 but not for TaG1, suggesting that treatment and surveillance of T1G1 carcinomas should be more like the approaches for T1G2 NMIBC in accordance with the intermediate and/or high risk categories of the European Association of Urology NMIBC guidelines. PATIENT SUMMARY: Although rare, stage T1 grade 1 (T1G1) bladder cancer is still diagnosed in daily clinical practice. Using individual patient data from 17 centers in Europe and Canada, we found that time to progression of T1G1 cancer was comparable to that for T1G2 but not TaG1 cancer. Therefore, our results suggest that primary T1G1 bladder cancers should be managed with more aggressive treatment and more frequent follow-up than for low-risk bladder cancer.

BACKGROUND: Prostate-specific membrane antigen (PSMA) targeted molecular imaging using positron emission tomography (PET) has significantly improved the diagnosis and treatment of prostate cancer (PCA). OBJECTIVE: To assess the feasibility and compare the diagnostic accuracy of [68Ga]Ga-PSMA-11 PET images taken at baseline, before the initiation of systemic treatment and preoperative images, using histopathology after cytoreductive surgery as reference. DESIGN SETTING AND PARTICIPANTS: We identified 20 patients in our prospectively maintained database with primary oligometastatic PCA who underwent cytoreductive radical prostatectomy and superextended pelvic lymph node dissection after systemic therapy, who had baseline and preoperative [68Ga]Ga-PSMA-11 PET imaging available. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We performed a region-based analysis to determine the diagnostic accuracy of imaging, using pathology as a reference. Regions were predefined as prostate, internal iliac left/right, obturator left/right, external iliac left/right, common iliac left/right, and presacral. RESULTS AND LIMITATIONS: Sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and diagnostic effectiveness were, respectively, 95.65%, 78.22%, 98.39%, 57.89%, and 83.00% for baseline [68Ga]Ga-PSMA-11 PET, compared to 56.52%, 98.05%, 88.30%, 89.66%, and 88.50% for preoperative [68Ga]Ga-PSMA-11 PET. On a receiver operating characteristic analysis, the diagnostic accuracy of baseline [68Ga]Ga-PSMA-11 PET with an area under the curve (AUC) of 0.87 (95% confidence interval [CI] 0.83-0.92) was significantly better than that of preoperative [68Ga]Ga-PSMA-11 PET after systemic therapy with an AUC of 0.77 (95% CI 0.70-0.85, p = 0.01). CONCLUSIONS: Baseline imaging, [68Ga]Ga-PSMA-11 PET has significantly better diagnostic accuracy, sensitivity, and NPV than images obtained preoperatively, in systemically pretreated patients. If a patient is suitable for local treatment and complete resection of the residual tumor is intended, [68Ga]Ga-PSMA-11 PET images taken prior to systemic therapy are significantly more accurate in selecting the relevant lymph nodes for resection. PATIENT SUMMARY: We found that prostate-specific membrane antigen positron emission tomography (PSMA-PET) imaging used early, before hormonal therapy or chemotherapy, provides more accurate information about the spread of the disease, than if used immediately before surgery but after hormonal therapy or chemotherapy. Early use of PSMA-PET has the potential to improve therapy also at later stages of the disease.

PURPOSE: To evaluate the predictive and prognostic value of the Systemic Immune-inflammation Index (SII) in a large cohort of patients treated with radical prostatectomy (RP) for clinically non-metastatic prostate cancer (PCa). METHODS: We retrospectively analyzed our multicenter database comprising 6,039 consecutive patients. The optimal preoperative SII cut-off value was assessed with the Youden index calculated on a time-dependent receiver operating characteristic (ROC) curve. Logistic regression and Cox regression analyses were used to investigate the association of SII with pathologic features and biochemical recurrence (BCR), respectively. The discriminatory ability of the models was evaluated by calculating the concordance-indices (C-Index). The clinical benefit of the implementation of SII in clinical decision making was assessed using decision curve analysis (DCA). RESULTS: Patients with high preoperative SII (≥ 620) were more likely to have adverse clinicopathologic features. On multivariable logistic regression analysis, high preoperative SII was independently associated with extracapsular extension (odds ratio [OR] 1.16, P = 0.041), non-organ confined disease (OR 1.18, P = 0.022), and upgrading at RP (OR 1.23, P < 0.001). We built two Cox regression models including preoperative and postoperative variables. In the preoperative multivariable model, high preoperative SII was associated with BCR (hazard ratio [HR] 1.34, 95% CI 1.15-1.55, P < 0.001). In the postoperative multivariable model, SII was not associated with BCR (P = 0.078). The addition of SII to established models did not improve their discriminatory ability nor did it increase the clinical net benefit on DCA. CONCLUSION: In men treated with RP for clinically nonmetastatic PCa, high preoperative SII was statistically associated with an increased risk of adverse pathologic features at RP as well as BCR. However, it did not improve the predictive accuracy and clinical value beyond that obtained by current predictive and prognostic models. SII together with a panel of complementary biomarkers is praised to help guide decision-making in clinically nonmetastatic PCa.

PURPOSE: To evaluate the differential impact of postoperative radiotherapy (RT) on recurrence patterns in patients treated with radical prostatectomy (RP) using [68Ga]Ga-PSMAHBED-CC conjugate 11 positron emission tomography (PSMA 11-PET). METHODS: We assessed 162 consecutive patients who experienced biochemical recurrence (BCR) after RP for nonmetastatic prostate cancer (PC). All had at least one positive lesion on imaging. No patient was on androgen deprivation therapy (ADT). Patients were categorized into those who had received adjuvant/salvage RT ± ADT and those who did not (RP only). Lesion- and patient-based analyses were performed. The impact of the radiation field was assessed. RESULTS: Overall, 57 BCR patients underwent RP only, 105 received postoperative RT. Median PSA was 1.01 ng/ml (IQR 0.58-2). In the lesion-based analysis, compared to the RP only patients, those who had received postoperative RT, had less lymph node (LN) recurrences distal to the common iliac bifurcation (35.2 vs. 57.9%, p = 0.05), but were more likely to harbor positive LNs proximal to the iliac bifurcation and in the presacral (34.2 vs. 12.3%, p = 0.002) areas as well as bone metastases (25.7 vs. 8.8%, p = 0.01). In the patient-based analysis, the patients with postoperative RT after RP had less recurrence in the pelvis only (pelvic LNs and/or prostate bed) (52.4 vs. 79%, p = 0.002), but were more likely to harbor extrapelvic recurrence (41.9 vs. 15.8%, p = 0.001). Patients who received RT to the prostate bed only had more recurrence to the pelvic LN only (54.2% vs. 23.4%, p = 0.002), but less extrapelvic recurrence (31.3 vs. 53.2%, p = 0.03) and less bone recurrence (16.7 vs. 36.2%, p = 0.031) compared to those patients, who received RT to the prostate bed and pelvic nodes. CONCLUSIONS: Postoperative radiation treatment alters the recurrence pattern in BCR patients after RP. Further prospective studies are needed to establish a decision tree for optimal imaging/management according to previous treatments.

BACKGROUND: The European Association of Urology (EAU) prognostic factor risk groups for non-muscle-invasive bladder cancer (NMIBC) are used to provide recommendations for patient treatment after transurethral resection of bladder tumor (TURBT). They do not, however, take into account the widely used World Health Organization (WHO) 2004/2016 grading classification and are based on patients treated in the 1980s. OBJECTIVE: To update EAU prognostic factor risk groups using the WHO 1973 and 2004/2016 grading classifications and identify patients with the lowest and highest probabilities of progression. DESIGN, SETTING, AND PARTICIPANTS: Individual patient data for primary NMIBC patients were collected from the institutions of the members of the EAU NMIBC guidelines panel. INTERVENTION: Patients underwent TURBT followed by intravesical instillations at the physician's discretion. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Multivariable Cox proportional-hazards regression models were fitted to the primary endpoint, the time to progression to muscle-invasive disease or distant metastases. Patients were divided into four risk groups: low-, intermediate-, high-, and a new, very high-risk group. The probabilities of progression were estimated using Kaplan-Meier curves. RESULTS AND LIMITATIONS: A total of 3401 patients treated with TURBT ± intravesical chemotherapy were included. From the multivariable analyses, tumor stage, WHO 1973/2004-2016 grade, concomitant carcinoma in situ, number of tumors, tumor size, and age were used to form four risk groups for which the probability of progression at 5 yr varied from <1% to >40%. Limitations include the retrospective collection of data and the lack of central pathology review. CONCLUSIONS: This study provides updated EAU prognostic factor risk groups that can be used to inform patient treatment and follow-up. Incorporating the WHO 2004/2016 and 1973 grading classifications, a new, very high-risk group has been identified for which urologists should be prompt to assess and adapt their therapeutic strategy when necessary. PATIENT SUMMARY: The newly updated European Association of Urology prognostic factor risk groups for non-muscle-invasive bladder cancer provide an improved basis for recommending a patient's treatment and follow-up schedule.

BACKGROUND: Papillary urothelial neoplasm of low malignant potential (PUN-LMP) was introduced as a noninvasive, noncancerous lesion and a separate grade category in 1998. Subsequently, PUN-LMP was reconfirmed by World Health Organization (WHO) 2004 and WHO 2016 classifications for urothelial bladder tumors. OBJECTIVES: To analyze the proportion of PUN-LMP diagnosis over time and to determine its prognostic value compared to Ta-LG (low-grade) and Ta-HG (high-grade) carcinomas. To assess the intraobserver variability of an experienced uropathologist assigning (WHO) 2004/2016 grades at 2 time points. MATERIALS AND METHODS: Individual patient data of 3,311 primary Ta bladder tumors from 17 hospitals in Europe and Canada were available. Transurethral resection of the tumor was performed between 1990 and 2018. Time to recurrence and progression were analyzed with cumulative incidence functions, log-rank tests and multivariable Cox-regression stratified by institution. Intraobserver variability was assessed by examining the same 314 transurethral resection of the tumorslides twice, in 2004 and again in 2018. RESULTS: PUN-LMP represented 3.8% (127/3,311) of Ta tumors. The same pathologist found 71/314 (22.6%) PUN-LMPs in 2004 and only 20/314 (6.4%) in 2018. Overall, the proportion of PUN-LMP diagnosis substantially decreased over time from 31.3% (1990-2000) to 3.2% (2000-2010) and to 1.1% (2010-2018). We found no difference in time to recurrence between the three WHO 2004/2016 Ta-grade categories (log-rank, P = 0.381), nor for LG vs. PUN-LMP (log-rank, P = 0.238). Time to progression was different for all grade categories (log-rank, P < 0.001), but not between LG and PUN-LMP (log-rank, P = 0.096). Multivariable analyses on recurrence and progression showed similar results for all 3 grade categories and for LG vs. PUN-LMP. CONCLUSIONS: The proportion of PUN-LMP has decreased to very low levels in the last decade. Contrary to its reconfirmation in the WHO 2016 classification, our results do not support the continued use of PUN-LMP as a separate grade category in Ta tumors because of the similar prognosis for PUN-LMP and Ta-LG carcinomas.
