RESUMEN
PURPOSE: Patients with residual invasive bladder cancer after neoadjuvant chemotherapy (NAC) and radical cystectomy have a poor prognosis. Data on adjuvant therapy for these patients are conflicting. We sought to evaluate the natural history and genomic landscape of chemotherapy-resistant bladder cancer to inform patient management and clinical trials. METHODS: Data were collected on patients with clinically localized muscle-invasive urothelial bladder cancer treated with NAC and cystectomy at our institution between May 15, 2001, and August 15, 2019, and completed four cycles of gemcitabine and cisplatin NAC, excluding those treated with adjuvant therapies. Survival was estimated using the Kaplan-Meier method, and multivariable Cox proportional hazards models were used to identify predictors of recurrence-free survival (RFS). Genomic alterations were identified in targeted exome sequencing (Memorial Sloan Kettering Integrated Mutation Profiling of Actionable Cancer Targets) data from post-NAC specimens from a subset of patients. RESULTS: Lymphovascular invasion (LVI) was the strongest predictor of RFS (hazard ratio, 2.15 [95% CI, 1.37 to 3.39]) on multivariable analysis. Patients with ypT2N0 disease without LVI had a significantly prolonged RFS compared with those with LVI (70% RFS at 5 years). Lymph node yield did not affect RFS. Among patients with sequencing data (n = 101), chemotherapy-resistant tumors had fewer alterations in DNA damage response genes compared with tumors from a publicly available chemotherapy-naïve cohort (15% v 29%; P = .021). Alterations in CDKN2A/B were associated with shorter RFS. PIK3CA alterations were associated with LVI. Potentially actionable alterations were identified in more than 75% of tumors. CONCLUSION: Although chemotherapy-resistant bladder cancer generally portends a poor prognosis, patients with organ-confined disease without LVI may be candidates for close observation without adjuvant therapy. The genomic landscape of chemotherapy-resistant tumors is similar to chemotherapy-naïve tumors. Therapeutic opportunities exist for targeted therapies as adjuvant treatment in chemotherapy-resistant disease.

Importance: With the ongoing bacillus Calmette-Guèrin (BCG) shortage, alternate therapeutic options for patients with high-risk non-muscle-invasive bladder cancer (NMIBC) are needed. Objective: To report the 5-year outcomes of a cohort from a prospective phase 2 trial of patients with high-risk NMIBC who underwent 12 instillations of induction BCG without maintenance. Design, Setting, and Participants: Between November 2015 and June 2018, patients at Memorial Sloan Kettering Cancer Center with primary or recurrent NMIBC (high-grade Ta, T1 tumors, with or without carcinoma in situ) were prospectively enrolled to receive 2 induction courses (12 intravesical instillations) of BCG without maintenance therapy. The analysis itself took place on July 28, 2023. Main Outcomes and Measures: Recurrence-free survival (RFS) and cancer-specific survival (CSS) was assessed by landmark analysis at 7.5 months. Recurrence was defined as pathologic high-grade disease. Results: Among 81 patients (65 men [84%] and 12 women [16%] with a median [IQR] age of 72 [64-77] years) who consented to participate in the study, 75 remained evaluable for long-term follow-up analysis. Twenty-one patients experienced high-grade recurrence, yielding a 5-year RFS rate of 69% (95% CI, 58%-81%), with a median (IQR) follow-up of 4.4 (3.8-5.3) years for patients without recurrence. Three patients died of bladder cancer, corresponding to a CSS rate of 97% (95% CI, 93%-100%) with a median (IQR) follow-up of 4.9 (4.2-5.7) years for survivors. Using 2 induction courses reduced the amount of BCG per patient from 27 vials to 12 vials. Conclusion and Relevance: Twelve induction instillations of BCG without maintenance for patients with high-risk NMIBC reduced the number of vials needed per patient while providing acceptable oncologic outcomes. Given the ongoing BCG shortage, this modified regimen may provide a suitable alternative in this setting.

INTRODUCTION: We evaluated surgical trends, perioperative management evolution, and oncologic outcomes in patients who underwent radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) at a tertiary cancer center over a 24-year period. METHODS: Between 1995 and 2018, we evaluated 743 consecutive patients with UTUC who underwent RNU. Generalized additive models were used to estimate the associations between date of surgery and continuous outcomes using a linear model, dichotomous outcomes using a logit link, categorical outcomes using multinomial models, and 2- and 5-year survival outcomes using Cox proportional hazards models. RESULTS: Over the study period, preoperative diagnostic endoscopic biopsies increased from 10% to 66%, along with the proportion of patients who underwent RNU for high-grade disease from 55% to 91%. The rate of open RNU declined from 100% to 56% with a rise in minimally invasive approaches. Median lymph node yield increased with more retroperitoneal lymph node dissections performed. Neoadjuvant chemotherapy utilization increased with a contemporary utilization rate of 32%, coinciding with an increase in pT0 rate from 2% to 8%. Cancer-specific survival probabilities improved over the study period, while metastasis-free and overall survival remained stable. CONCLUSIONS: We found several changes in treatment patterns and outcomes for patients with UTUC over the past 2 decades. How individual alterations in management factors, such as patient selection, perioperative chemotherapy, lymphadenectomy, and salvage therapies, impact patient outcomes is challenging in the setting of multiple overlapping practice changes for this rare disease and warrants further investigation.

BACKGROUND: There is limited ability to accurately diagnose and clinically stage patients with upper tract urothelial carcinoma (UTUC). The most easily available and widely used urinary biomarker is urine cytology, which evaluates cellular material yet lacks sensitivity. We sought to assess the feasibility of performing next-generation sequencing (NGS) on urine cytology specimens from patients with UTUC and evaluate the genomic concordance with tissue from primary tumor. METHODS: In this retrospective study, we identified 48 patients with a diagnosis of UTUC treated at Memorial Sloan Kettering Cancer Center (MSK) between 2019 and 2022 who had banked or fresh urine samples. A convenience cohort of matching, previously sequenced tumor tissue was used when available. Urine specimens were processed and the residual material, including precipitated cell-free DNA, was sequenced using our tumor-naïve, targeted exome sequencing platform that evaluates 505 cancer-related genes (MSK-IMPACT). The primary outcome was at least 1 detectable mutation in urinary cytology specimens. The secondary outcome was concordance to matched tissue (using ANOVA or Chi-Square, as indicated). RESULTS: Genomic sequencing was successful for 45 (94%) of the 48 urinary cytology patient samples. The most common mutations identified were TERT (62.2%), KMT2D (46.7%), and FGFR3 (35.6%). All patients with negative urine cytology and low-grade tissue had successful cytology sequencing. Thirty-six of the 45 patients had matching tumor tissue available; concordance to matched tissue was 55% overall (131 of the total 238 oncogenic or likely oncogenic somatic mutations identified). However, in 94.4% (nâ¯=â¯34/36) of patients, the cytology had at least 1 shared mutation with tissue. Eleven (30.6%) patients had 100% concordance between cytology and tissue. CONCLUSIONS: Sequencing urinary specimens from selective UTUC cytology is feasible in nearly all patients with UTUC. Prospective studies are underway to investigate a clinical role for this promising technology.

PURPOSE: We compare health-related quality of life using a broad range of validated measures in patients randomized to robotic-assisted radical cystectomy vs open radical cystectomy. METHODS: We retrospectively analyzed patients that had enrolled in both a randomized controlled trial comparing robotic-assisted laparoscopic radical cystectomy vs open radical cystectomy and a separate prospective study of health-related quality of life. The prospective health-related quality of life study collected 14 patient-reported outcomes measures preoperatively and at 3, 6, 12, 18, and 24 months postoperatively. Linear mixed-effects models with an interaction term (study arm×time) were used to test for differences in mean domain scores and differing effects of approach over time, adjusting for baseline scores. RESULTS: A total of 72 patients were analyzed (n=32 robotic-assisted radical cystectomy, n=40 open radical cystectomy). From 3-24 months post-radical cystectomy, no significant differences in mean scores were detected. Mean differences were small in the following European Organization for Research and Treatment of Cancer QLQ-C30 (Core Quality of Life Questionnaire) domains: Global Quality of Life (-1.1; 95% CI -8.4, 6.2), Physical Functioning (-0.4; 95% CI -5.8, 5.0), Role Functioning (0.7; 95% CI -8.6, 10.0). Mean differences were also small in bladder cancer-specific domains (European Organization for Research and Treatment of Cancer QLQ-BLM30 [Muscle Invasive Bladder Cancer Quality of Life Questionnaire]): Body Image (2.9; 95% CI -7.2, 13.1), Urinary Symptoms (8.0; 95% CI -3.0, 19.0). In Urostomy Symptoms, there was a significant interaction term (P < .001) due to lower open radical cystectomy scores at 3 and 24 months. Other domains evaluating urinary, bowel, sexual, and psychosocial health-related quality of life were similar. CONCLUSIONS: Over a broad range of health-related quality of life domains comparing robotic-assisted radical cystectomy and open radical cystectomy, there are unlikely to be clinically relevant differences in the medium to long term, and therefore health-related quality of life over this time period should not be a consideration in choosing between approaches.

PURPOSE: Vascular-targeted photodynamic therapy with the intravascular photosensitizing agent padeliporfin (WST-11/TOOKAD-Soluble) has demonstrated therapeutic efficacy as an ablative treatment for localized cancer with potential adaptation for endoscopic management of upper tract urothelial carcinoma. This Phase I trial (NCT03617003) evaluated the safety of vascular-targeted photodynamic therapy with WST-11 in upper tract urothelial carcinoma. MATERIALS AND METHODS: Nineteen patients underwent up to 2 endoscopic vascular-targeted photodynamic therapy treatments, with follow-up for up to 6 months. Patients who had residual or recurrent upper tract urothelial carcinoma (any grade/size) failing prior endoscopic treatment or unable or unwilling to undergo surgical resection were eligible for inclusion. The primary endpoint was to identify the maximally tolerated dose of laser light fluence. A dose escalation model was employed, with increasing light fluence (100-200 mW/cm) using a modified continual reassessment method. The secondary endpoint was treatment efficacy, defined by absence of visible tumor and negative urine cytology 30 days posttreatment. RESULTS: Fourteen (74%) patients received the maximally tolerated dose of 200 mW/cm, 2 (11%) of whom experienced a dose-limiting toxicity. The initial 30-day treatment response rate was 94% (50% complete, 44% partial). Eight patients underwent a second treatment, with a final observed 68% complete response rate. Leading toxicities were flank pain (79%) and hematuria (84%), which were transient. No ureteral strictures associated with treatment were identified during follow-up. CONCLUSIONS: Vascular-targeted photodynamic therapy with WST-11 has an acceptable safety profile with strong potential as an effective, kidney-sparing endoscopic management option for upper tract urothelial carcinoma. The recently initiated multicenter Phase 3 ENLIGHTED trial (NCT04620239) is expected to provide further evidence on this therapy.

PURPOSE: Neoadjuvant chemotherapy (NAC) has proven survival benefits for patients with invasive urothelial carcinoma of the bladder, yet its role for upper tract urothelial carcinoma (UTUC) remains undefined. We conducted a multicenter, single-arm, phase II trial of NAC with gemcitabine and split-dose cisplatin (GC) for patients with high-risk UTUC before extirpative surgery to evaluate response, survival, and tolerability. METHODS: Eligible patients with defined criteria for high-risk localized UTUC received four cycles of split-dose GC before surgical resection and lymph node dissection. The primary study end point was rate of pathologic response (defined as < ypT2N0). Secondary end points included progression-free survival (PFS), overall survival (OS), and safety and tolerability. RESULTS: Among 57 patients evaluated, 36 (63%) demonstrated pathologic response (95% CI, 49 to 76). A complete pathologic response (ypT0N0) was noted in 11 patients (19%). Fifty-one patients (89%) tolerated at least three complete cycles of split-dose GC, 27 patients (47%) tolerated four complete cycles, and all patients proceeded to surgery. With a median follow up of 3.1 years, 2- and 5-year PFS rates were 89% (95% CI, 81 to 98) and 72% (95% CI, 59 to 87), while 2- and 5-year OS rates were 93% (95% CI, 86 to 100) and 79% (95% CI, 67 to 94), respectively. Pathologic complete and partial responses were associated with improved PFS and OS compared with nonresponders (≥ ypT2N any; 2-year PFS 100% and 95% v 76%, P < .001; 2-year OS 100% and 100% v 80%, P < .001). CONCLUSION: NAC with split-dose GC for high-risk UTUC is a well-tolerated, effective therapy demonstrating evidence of pathologic response that is associated with favorable survival outcomes. Given that these survival outcomes are superior to historical series, these data support the use of NAC as a standard of care for high-risk UTUC, and split-dose GC is a viable option for NAC.

BACKGROUND: Mucosal melanoma involving the urethra is a rare disease with distinct clinical and molecular characteristics and poor outcomes. Our current knowledge is limited by the small number of reports regarding this disease. OBJECTIVE: To describe the clinical, pathological, and molecular characteristics of urethral melanoma. METHODS: We summarized the clinicopathologic data for 31 patients treated for urethral melanoma from 1986-2017 at our institution. Genomic data from our institutional sequencing platform MSK-IMPACT (nâ=â5) and gene-specific PCR data on BRAF, KIT, and/or NRAS (nâ=â8) were compared to genomic data of cutaneous melanomas (nâ=â143), vulvar/vaginal melanomas (nâ=â24), and primary non-melanoma urethral tumors (nâ=â5) from our institutional database. RESULTS: Twenty-three patients were diagnosed with localized disease, 7 had regional/nodal involvement and one had metastases. Initial treatment included surgery in 25 patients; seven had multimodal treatment. Median follow-up was 46 months (IQR 33-123). Estimated 5-year cancer-specific survival was 45%. No significant change in survival was observed based on a year of treatment.Primary urethral melanomas showed a higher frequency of TP53 mutations compared to cutaneous (80.0% vs. 18.2%, pâ=â0.006) and vulvar/vaginal melanomas (80.0 vs. 25.0%, pâ=â0.04). BRAF mutations were absent in urethral primaries (0% vs. 46% in cutaneous melanoma, pâ=â0.02). Tumor mutation burden was higher in cutaneous than urethral melanomas (pâ=â0.04). Urethral melanomas had a higher number of somatic alterations compared to non-melanoma urethral tumors (median 11 vs. 5, pâ=â0.03). CONCLUSIONS: Our findings support a unique mutational landscape of urethral melanoma compared to cutaneous melanoma. Survival remains poor and is unchanged over the time studied.
RESUMEN
PURPOSE: To compare oncologic outcomes and genomic alteration profiles in patients with bladder and urachal adenocarcinoma, urothelial carcinoma (UC) with glandular differentiation, and UC, not otherwise specified (NOS) undergoing surgical resection, with emphasis on response to systemic therapy. METHODS: We identified patients with bladder cancer with glandular variants who underwent surgical resection at Memorial Sloan Kettering from 1995 to 2018 (surgical cohort) and/or patients who had tumor sequencing using a targeted next-generation sequencing platform (genomics cohort). Pathologic complete and partial response rates to neoadjuvant chemotherapy (NAC) and recurrence-free and cancer-specific survival were measured. Alteration frequencies between histologic subtypes were compared. RESULTS: Thirty-seven patients with bladder adenocarcinoma, 46 with urachal adenocarcinoma, 84 with UC with glandular differentiation, and 1,049 with UC, NOS comprised the surgical cohort. Despite more advanced disease in patients with bladder and urachal adenocarcinoma, no significant differences in recurrence or cancer-specific survival by histology were observed after adjusting for stage. In patients with UC with glandular differentiation, NAC resulted in partial (≤ pT1N0) and complete (pT0N0) responses in 28% and 17%, respectively. Bladder and urachal adenocarcinoma genomic profiles resembled colorectal adenocarcinoma with frequent TP53, KRAS, and PIK3CA alterations while the genomic profile of UC with glandular differentiation more closely resembled UC, NOS. Limitations include retrospective nature of analysis and small numbers of nonurothelial histology specimens. CONCLUSION: The genomic profile of bladder adenocarcinomas resembled colorectal adenocarcinomas, whereas UC with glandular differentiation more closely resembled UC, NOS. Differences in outcomes among patients with glandular bladder cancer variants undergoing surgical resection were largely driven by differences in stage. Cisplatin-based NAC demonstrated activity in UC with glandular differentiation, suggesting NAC should be considered for this histologic variant.

INTRODUCTION: Small cell carcinoma of the bladder (SCCB) is a rare variant of bladder cancer with poor outcomes. We evaluated long-term outcomes of nonmetastatic (M0) and metastatic (M1) SCCB and correlated pathologic response with genomic alterations of patients treated with neoadjuvant chemotherapy (NAC). PATIENTS AND METHODS: Clinical history and pathology samples from SCCB patients diagnosed at our institution were reviewed. RESULTS: One hundred and ninety-nine SCCB patients were identified. (M0: 147 [74%]; M1: 52 [26%]). Among M0 patients, 108 underwent radical cystectomy (RC) (NAC: 71; RC only: 23; adjuvant chemotherapy: 14); 14 received chemoradiotherapy; the rest received chemotherapy alone or no cancer-directed therapy. RC-only patients had a median follow-up of 9.1 years, and median disease-free survival (DFS) and overall survival (OS) were 1.1 and 1.2 years, respectively. NAC patients had pathologic response (Asunto(s)

RESUMEN
OBJECTIVES: To analyse the risk of uretero-enteric anastomotic stricture in patients randomised to open (ORC) or robot-assisted radical cystectomy (RARC) with extracorporeal urinary diversion. PATIENTS AND METHODS: We included 118 patients randomised to RARC (n = 60) or ORC (n = 58) at a single, high-volume institution from March 2010 to April 2013. Urinary diversion was performed by experienced open surgeons. Stricture was defined as non-malignant obstruction on imaging, corroborated by clinical status, and requiring procedural intervention. The risk of stricture within 1 year was compared between groups using Fisher's exact test. RESULTS: In all, 58 and 60 patients were randomised to RARC and ORC, respectively. We identified five strictures, all in the ORC group. In patients with ≥1 year of follow-up, the increase in risk of stricture from open surgery was 9.3% (95% confidence interval 1.5%, 17%). Of the five strictures, three were managed endoscopically while two required open revision. There was no evidence that perioperative Grade 3-5 complications were associated with development of a stricture (P = 1) and no evidence of a difference in 24-month estimated glomerular filtration rate between arms (P = 0.15). CONCLUSIONS: In this study at a high-volume centre, RARC with extracorporeal urinary diversion achieved excellent ureteric anastomotic outcomes. Purported increased risk of stricture is not a reason to avoid RARC. Future research should examine the impact of different surgical techniques and operator experience on the risk of stricture, especially as more intracorporeal diversions are performed.

BACKGROUND: Retrospective studies have shown the beneficial impact of geriatric comanagement (GERICO) on perioperative outcomes of older adults with cancer. We prospectively assessed the feasibility of perioperative GERICO for older adults with bladder cancer undergoing radical cystectomy. METHODS: We conducted a pilot study wherein all patients 75 years and older undergoing radical cystectomy between October 2019 and November 2020 were referred to the Geriatric Service preoperatively. Feasibility was defined according to the percentage of patients who received preoperative evaluation by the Geriatrics Service, who were followed for more than 80% of their inpatient days and who had their surgery rescheduled for logistical reasons. Urology advanced practice provider (APP) satisfaction with the program was measured via an 11-item survey. RESULTS: Sixty-six eligible patients underwent radical cystectomy in the stated time frame; 59 (89%; 95% confidence interval [CI], 79-97%) were referred to the Geriatric Service for evaluation. The median age of patients who had geriatric comanagement was 79 years; 40 (68%) were male. Forty-one patients (69%) were visited on at least 80% of the days in which they were not in the intensive care unit. No surgeries were rescheduled for logistical reasons. Nine of the 12 urology APPs (75%) responded to the survey; all nine "somewhat" or "strongly" agreed with statements indicating satisfaction with the program. CONCLUSION: Despite the challenges of the COVID-19 pandemic, we showed that perioperative GERICO is feasible. Fully powered prospective randomized controlled trials should be conducted to assess GERICO's impact on perioperative outcomes of older adults with cancer.

PURPOSE: Our goal was to determine the association between biochemically verified post-diagnosis smoking exposure and nonmuscle-invasive bladder cancer (NMIBC) recurrence risk. MATERIALS AND METHODS: We conducted a prospective study of 354 NMIBC patients with a smoking history undergoing care between 2015 and 2018. Patients contributed at least 2 biospecimens during followup which were tested for cotinine to determine biochemically verified post-diagnosis smoking exposure (yes/no). Our primary endpoint was time to first recurrence after study start date. We examined whether post-diagnosis smoking exposure was associated with recurrence risk in multivariable Cox proportional hazards models that accounted for demographics, clinicopathological variables, time since diagnosis and pack-years. RESULTS: Patients were predominantly White, male and had a median age of 68 years. Most patients had Ta disease (62%) and tumors of high grade (68%). Intravesical bacillus Calmette-Guérin was given to 63% of the cohort. Patients were followed for a median of 3.6 years since study start. Post-diagnosis smoking exposure was detected in 22% of patients, and 38.7% (137) of patients experienced a recurrence during followup. In multivariable models, only bacillus Calmette-Guérin treatment and prior recurrence rate were significantly associated with recurrence. There was no association between post-diagnosis smoking exposure and recurrence risk (HR: 0.73, 95% CI: 0.45-1.20). CONCLUSIONS: In a cohort of patients with predominantly high risk NMIBC, post-diagnosis smoking exposure was not associated with NMIBC recurrence. However, smoking cessation support remains a critical component of cancer care given that the benefits of quitting extend far beyond NMIBC recurrence.

BACKGROUND: Radical cystectomy (RC) has the potential for profound changes to health-related quality of life (HRQOL). OBJECTIVE: To evaluate a broad range of HRQOL outcomes in a large RC cohort. DESIGN, SETTING, AND PARTICIPANTS: A single-center prospective study enrolled RC patients from 2008 to 2014. We collected 14 separate patient-reported outcome measures at the presurgical visit and at 3, 6, 12, 18, and 24 mo after RC. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: To visualize the patterns of recovery over time across domains, we used generalized estimating equations (GEEs) with nonlinear terms. Given substantial differences in patient selection for the type of urinary diversion, we separately modeled longitudinal HRQOL within conduit and continent diversion groups. The mean pre-RC scores were compared to illustrate the baseline HRQOL differences between diversion groups. RESULTS AND LIMITATIONS: The analyzed cohort included 411 patients (n = 205 ileal conduit, n = 206 continent diversion). At baseline, patients receiving continent diversion reported better mean physical (p < 0.001), urinary (p = 0.006), and sexual function (p < 0.001), but lower social function (p = 0.015). After RC, GEE modeling showed physical function scores decreasing 5/100 points by 6 mo, and subsequently stabilizing or returning to baseline. By 12 mo, social function improved by 10/100 points among continent diversions, while remaining stable among ileal conduits. Global quality of life exceeded baseline scores by 6 mo. Sexual function scores were low before RC, with limited recovery. Psychosocial domains were stable or improved, except for 10/100-point worsening of body image among ileal conduits. CONCLUSIONS: RC patients reported favorable HRQOL recovery within 24 mo in most areas other than body image (ileal conduits) and sexual function (both). Importantly, large measurable decreases in scores were not reported by 3 mo after RC. These contemporary outcomes and the excellent locoregional control provided by RC further support it as the gold standard therapy for high-risk bladder cancer. PATIENT SUMMARY: We review quality of life in the 24 mo following radical cystectomy. Large decreases in health-related quality of life were not reported, with most areas returning to, or exceeding, baseline, except for sexual function and body image.

OBJECTIVE: To evaluate whether urothelial carcinoma (UC) with sarcomatoid differentiation is associated with a lower pathological response rate to neoadjuvant chemotherapy (NAC) and worse oncological outcomes compared to UC without variant histology among patients undergoing radical cystectomy. PATIENTS AND METHODS: Patients with UC undergoing cystectomy from 1995 to 2018 at the Memorial Sloan Kettering Cancer Centre were identified. Patients with sarcomatoid differentiation at transurethral resection (TUR) or cystectomy, and patients without variant histology were selected. Downstaging from ≥cT2 to ≤pT1N0 defined partial response and pT0N0 defined complete response. Recurrence-free, cancer-specific and overall survival were modelled. RESULTS: We identified 131 patients with sarcomatoid differentiation and 1722 patients without variant histology, of whom 25 with sarcomatoid histology on biopsy and 313 without variant histology received NAC. Those with sarcomatoid differentiation presented with higher consensus tumour stage (94% ≥T2 vs 62%; P < 0.001) and were, therefore, more likely to receive NAC (29% vs 18%; P = 0.003). We found no evidence to support a difference in partial (24% vs 31%) or complete (20% vs 24%) response between patients with sarcomatoid histology and those with pure UC at TUR (P = 0.6). Among patients with sarcomatoid differentiation, 5-year recurrence-free survival was 55% (95% confidence interval [CI] 41-74) among patients receiving NAC and 40% (95% CI 31-52) among patients undergoing cystectomy alone (P = 0.1). Adjusting for stage, nodal involvement, margin status and receipt of NAC, sarcomatoid differentiation was associated with worse recurrence-free (hazard ratio [HR] 1.82, 95% CI 1.39-2.39), disease-specific (HR 1.66, 95% CI 1.23-2.22), and overall survival (HR 1.37, 95% CI 1.06-1.78). CONCLUSIONS: Sarcomatoid differentiation was associated with higher stage at presentation and independently associated with worse survival. Given similar pathological response rates if sarcomatoid differentiation is detected at initial resection, and greater survival among patients receiving NAC, treatment with NAC appears warranted. Other drivers of the poor outcomes of this histology must be investigated.

OBJECTIVE: To test whether 2 sequential BCG-induction courses improve the response of high-risk non-muscle invasive bladder cancer. Achieving a complete response (CR) to BCG is critical to disease-free survival. Patients with preexisting BCG-specific immunity owing to prior exposure to BCG have longer disease-free survival than BCG-naïve patients likely due to heterologous immunity from the initial priming of the immune system. We evaluated this hypothesis in a phase II prospective clinical trial. METHODS: From 2015 to 2018, we recruited patients with primary or recurrent NMIBC (high-grade Ta, T1 tumors, with or without CIS) to receive 2-induction courses (12 intra-vesical instillations) of BCG. The primary aim of the study was CR rate 6 months after start of the first BCG induction. CR was defined as no tumor at cystoscopy or TURB biopsy. No maintenance BCG was given. We targeted at least 75 evaluable patients, and a CR of 80% or better was deemed significant. RESULTS: Eighty-one patients agreed to participate. Five withdrew before starting BCG, leaving 76 evaluable patients. Sixty-three patients (83%) completed the 12 instillations on schedule. Of these, 62 patients (91%) had a CR at 6 months. None of the patients had tumor progression. Serious adverse event was seen in 1 patient (1%). Recurrence-free survival at 2 years after complete response was 85% (95% CI 77%, 95%). CONCLUSION: The high response rate in patients with high-risk non-muscle-invasive bladder cancer justifies 2 BCG induction cycles in current practice.

The Genitourinary Pathology Society (GUPS) undertook a critical review of the recent advances in bladder neoplasia with a focus on issues relevant to the practicing surgical pathologist for the understanding and effective reporting of bladder cancer, emphasizing particularly on the newly accumulated evidence post-2016 World Health Organization (WHO) classification. The work is presented in 2 manuscripts. Here, in the first, we revisit the nomenclature and classification system used for grading flat and papillary urothelial lesions centering on clinical relevance, and on dilemmas related to application in routine reporting. As patients of noninvasive bladder cancer frequently undergo cystoscopy and biopsy in their typically prolonged clinical course and for surveillance of disease, we discuss morphologies presented in these scenarios which may not have readily applicable diagnostic terms in the WHO classification. The topic of inverted patterns in urothelial neoplasia, particularly when prominent or exclusive, and beyond inverted papilloma has not been addressed formally in the WHO classification. Herein we provide a through review and suggest guidelines for when and how to report such lesions. In promulgating these GUPS recommendations, we aim to provide clarity on the clinical application of these not so uncommon diagnostically challenging situations encountered in routine practice, while also importantly advocating consistent terminology which would inform future work.
