Clin Genitourin Cancer 2023; 21:e326-e333. [PMID: 37211451 DOI: 10.1016/j.clgc.2023.03.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 03/24/2023] [Accepted: 03/26/2023] [Indexed: 05/23/2023]
Abstract
AIM Optimal utilization of perioperative systemic therapy in locally advanced bladder cancer (LABC) holds the key in improving the survival outcomes. We aim to analyze the oncological outcomes of clinically locally advanced urothelial bladder cancer patients treated with neoadjuvant (NACT) or adjuvant chemotherapy or without any systemic therapy in the perioperative period of radical cystectomy. METHODS & MATERIAL We retrospectively analyzed the medical records of patients with cancer of the urinary bladder diagnosed between 2012 and 2020. The demographic profile, and the treatment received, was recorded for all patients. Oncological outcomes of the patients based on these variables were analyzed. RESULTS Two hundred and twenty nine (229) locally advanced bladder cancer patients were included in the study. Eighty eight (38%) of them underwent upfront radical cystectomy and 141 (62%) received neoadjuvant chemotherapy (NACT). With a median follow-up of 27 months, the 2-year DFS in either of the groups was 65.4% and 67.1% respectively (P - 0.373). In the multivariate analysis, the pathological lymph nodal status and lymph vascular invasion (LVI) status influenced the DFS. The initial modality of management chosen did not affect the outcome. (HR - 0.688; 95% CI: 0.38-1.21). The commonest reason for not receiving NACT was Cisplatin ineligibility due to malignant obstructive uropathy and a subgroup analysis of this set of patients also did not show any significant difference in 2 year DFS compared to those who received NACT. CONCLUSION A significant proportion of patients with LABC are unable to receive the recommended neoadjuvant chemotherapy and obstructive uropathy is the commonest reason for this in our centre. In our single centre series upfront radical cystectomy followed by adjuvant platinum based therapy had an outcome similar to neoadjuvant chemotherapy in LABC patients, in patients who were unable to receive the same due to various reasons.

Clin Oncol (R Coll Radiol) 2023; 35:e506-e515. [PMID: 37208232 DOI: 10.1016/j.clon.2023.04.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 04/10/2023] [Accepted: 04/28/2023] [Indexed: 05/21/2023]
Abstract
AIMS To assess the efficacy and safety of adjuvant radiotherapy in patients with high-risk muscle-invasive bladder cancer (MIBC) following radical cystectomy (RC) and chemotherapy. MATERIALS AND METHODS The BART (Bladder Adjuvant RadioTherapy) trial is an ongoing multicentric, randomised, phase III trial comparing the efficacy and safety of adjuvant radiotherapy versus observation in patients with high-risk MIBC. The key eligibility criteria include ≥pT3, node-positive (pN+), positive margins and/or nodal yield <10, or, neoadjuvant chemotherapy for cT3/T4/N+ disease. In total, 153 patients will be accrued and randomised, in a 1:1 ratio, to either observation (standard arm) or adjuvant radiotherapy (test arm) following surgery and chemotherapy. Stratification parameters include nodal status (N+ versus N0) and chemotherapy (neoadjuvant chemotherapy versus adjuvant chemotherapy versus no chemotherapy). For patients in the test arm, adjuvant radiotherapy to cystectomy bed and pelvic nodes is planned with intensity-modulated radiotherapy to a dose of 50.4 Gy in 28 fractions using daily image guidance. All patients will follow-up with 3-monthly clinical review and urine cytology for 2 years and subsequently 6 monthly until 5 years, with contrast-enhanced computed tomography abdomen pelvis 6 monthly for 2 years and annually until 5 years. Physician-scored toxicity using Common Terminology Criteria for Adverse Events version 5.0 and patient-reported quality of life using the Functional Assessment of Cancer Therapy - Colorectal questionnaire is recorded pre-treatment and at follow-up. ENDPOINTS AND STATISTICS The primary endpoint is 2-year locoregional recurrence-free survival. The sample size calculation was based on the estimated improvement in 2-year locoregional recurrence-free survival from 70% in the standard arm to 85% in the test arm (hazard ratio 0.45) using 80% statistical power and a two-sided alpha error of 0.05. Secondary endpoints include disease-free survival, overall survival, acute and late toxicity, patterns of failure and quality of life. CONCLUSION The BART trial aims to evaluate whether contemporary radiotherapy after standard-of-care surgery and chemotherapy reduces pelvic recurrences safely and also potentially affects survival in high-risk MIBC.

Long-Term Outcome of Patients with Stage II and III Muscle-Invasive Urothelial Bladder Cancer after Multimodality Approach. Which Is the Best Option? Medicina (B Aires) 2022; 59:medicina59010050. [PMID: 36676675 PMCID: PMC9865683 DOI: 10.3390/medicina59010050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 12/18/2022] [Accepted: 12/22/2022] [Indexed: 12/29/2022] Open
Abstract
Background and Objectives: There is no consensus regarding the optimal therapy sequence in stage II and III bladder cancer. The study aimed to evaluate the long-term oncologic outcomes in patients with bladder cancer after a multimodality approach. Materials and methods: Medical files of 231 consecutive patients identified with stage II (46.8%), IIIA (30.3%), and IIIB (22.9%) transitional cell carcinoma of the bladder (BC) treated with a multimodality approach were retrospectively reviewed. The treatment consisted of transurethral resections or cystectomy, radiotherapy alone or concurrent chemoradiotherapy as definitive treatment, or neoadjuvant chemotherapy using platinum salt regimens. Results: Median age at diagnosis was 65 ± 10.98 years. Radical or partial cystectomy was performed in 88 patients (37.1%), and trans-urethral resection of bladder tumor (TURBT) alone was performed in 143 (61.9%) patients. Overall, 40 patients (17.3%) received neoadjuvant chemotherapy and 82 (35.5%) received definitive chemoradiotherapy. After a median follow-up of 30.6 months (range 3-146 months), the median disease-free survival (DFS) for an entire lot of patients was 32 months, and the percentage of patients without recurrence at 12, 24, and 36 months was 86%, 58%, and 45%, respectively. Patients receiving neoadjuvant chemotherapy had a better oncologic outcome compared to patients without neoadjuvant chemotherapy (median DFS not reached vs. 31 months, p = 0.038, HR = 0.55, 95% CI 0.310-0.951). There was a trend for better 3-year DFS with radical cystectomy vs. TURBT (60 months vs. 31 months, p = 0.064). Definitive chemoradiotherapy 3-year DFS was 58% compared to 44% in patients who received radiotherapy or chemotherapy alone. Conclusions: In patients with stages II and III, both neoadjuvant chemotherapy and concurrent radio-chemotherapy are valid options for treatment and must be part of a multidisciplinary approach.

Selecting the Best Candidates for Cisplatin-based Adjuvant Chemotherapy After Radical Cystectomy Among Patients with pN+ Bladder Cancer. Eur Urol Oncol 2022; 5:722-725. [PMID: 35715319 DOI: 10.1016/j.euo.2022.04.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2022] [Revised: 03/07/2022] [Accepted: 04/11/2022] [Indexed: 01/26/2023]
Abstract
A trend towards greater benefit from adjuvant chemotherapy (ACT) in pN+ bladder cancer (BCa) has been observed in multiple randomized controlled trials. However, it is still unclear which patients might benefit the most from this approach. We retrospectively analyzed a multicenter cohort of 1381 patients with pTany pN1-3 cM0 R0 urothelial BCa treated with radical cystectomy (RC) with or without cisplatin-based ACT. The main endpoint was overall survival (OS) after RC. We performed 1:1 propensity score matching to adjust for baseline characteristics and conducted a classification and regression tree (CART) analysis to assess postoperative risk groups and Cox regression analyses to predict OS. Overall, 391 patients (28%) received cisplatin-based ACT. After matching, two cohorts of 281 patients with pN+ BCa were obtained. CART analysis stratified patients into three risk groups: favorable prognosis (≤pT2 and positive lymph node [PLN] count ≤2; odds ratio [OR] 0.43), intermediate prognosis (≥pT3 and PLN count ≤2; OR 0.92), and poor prognosis (pTany and PLN count ≥3; OR 1.36). Only patients with poor prognosis benefitted from ACT in terms of OS (HR 0.51; p < 0.001). We created the first algorithm that stratifies patients with pN+ BCa into prognostic classes and identified patients with pTany BCa with PLN ≥3 as the most suitable candidates for cisplatin-based ACT. PATIENT SUMMARY: We found that overall survival among patients with bladder cancer and evidence of lymph node involvement depends on cancer stage and the number of positive lymph nodes. Patients with more than three nodes affected by metastases seem to experience the greatest overall survival benefit from cisplatin-based chemotherapy after bladder removal. Our study suggests that patients with the highest risk should be prioritized for cisplatin-based chemotherapy after bladder removal.

Abstract
INTRODUCTION In regards to resectable muscle-invasive bladder cancer (MIBC) patients, contemporary guidelines recommend treatment with radical cystectomy and perioperative chemotherapy (neoadjuvant or adjuvant). In addition, the 5-year survival rate ranges from 36% to 48% in connection to T3 or T4 staged tumors or lymph node metastatic tumors. Perioperative treatment can improve overall survival, and the most robust evidence are in favor of neoadjuvant chemotherapy. The purpose of this study was to assess the impact of perioperative chemotherapy on the survival of patients with muscle-invasive bladder cancer (MIBC) who underwent radical cystectomy (RC). METHODS The medical records of ninety-four patients with muscle-invasive bladder cancer (MIBC) that were treated with radical cystectomy and perioperative chemotherapy from 2008 to 2018 were retrospectively analyzed at Songklanagarind hospital. Neoadjuvant and adjuvant chemotherapy groups were classified. Univariable and multivariable regression analyses were used to predict overall survival (OS) after treatment. The survival rates for each group were estimated and compared using long-rank testing. RESULTS Overall, we identified 94 eligible patients of whom 20 patients (21.2%) received neoadjuvant and 74 patients (78.8%) received adjuvant chemotherapy. The 5-year survival rate of the neoadjuvant group was 55.7%, and in regards to the adjuvant group it was 30.4%. A multivariable analysis yielded that, patients treated with neoadjuvant chemotherapy had longer survival than those treated with adjuvant chemotherapy (p =0.039). The median survival here as log rank compares median survival. CONCLUSION The overall survival of neoadjuvant chemotherapy (NAC) was better than adjuvant chemotherapy (AC) in regards to muscle-invasive bladder cancer. These data could support the use of neoadjuvant chemotherapy in MIBC prior to radical cystectomy.

Abstract
Simple Summary Bladder cancer is the ninth most common cancer worldwide. Immune checkpoint inhibitors, a novel class of immunotherapy drugs that restore natural antitumoral immune activity, have been applied to improve the overall survival and to reduce the morbidity and mortality of bladder cancer both in neoadjuvant and adjuvant settings. However, some patients do not respond to checkpoint inhibitors. Consequently, the capability for identifying patients eligible for this type of immunotherapy represent one of the efforts of ongoing studies. We aim to summarize the most recent evidence on immune checkpoint inhibitors in neoadjuvant and adjuvant setting in the treatment of muscle-invasive bladder cancer. Abstract Bladder cancer is the ninth most common cancer worldwide. Over 75% of non-muscle invasive cancer patients require conservative local treatment, while the remaining 25% of patients undergo radical cystectomy or radiotherapy. Immune checkpoint inhibitors represent a novel class of immunotherapy drugs that restore natural antitumoral immune activity via the blockage of inhibitory receptors and ligands expressed on antigen-presenting cells, T lymphocytes and tumour cells. The use of immune checkpoint inhibitors in bladder cancer has been expanded from the neoadjuvant setting, i.e., after radical cystectomy, to the adjuvant setting, i.e., before the operative time or chemotherapy, in order to improve the overall survival and to reduce the morbidity and mortality of both the disease and its treatment. However, some patients do not respond to checkpoint inhibitors. As result, the capability for identifying patients that are eligible for this immunotherapy represent one of the efforts of ongoing studies. The aim of this systematic review is to summarize the most recent evidence regarding the use of immune checkpoint inhibitors, in a neoadjuvant and adjuvant setting, in the treatment of muscle-invasive bladder cancer.

Abstract
Background Management of bladder cancer (BLCA) has not changed significantly in the past few decades, with platinum agent chemotherapy being used in most cases. Chemotherapy reduces tumor recurrence after resection, but debilitating toxicities render a large percentage of patients ineligible. Recently approved immunotherapy can improve outcomes in only a third of metastatic BLCA patients. Therefore, more options for therapy are needed. In this study, we explored the efficacy of PARP inhibitors (PARPi) as single agents or as combinations with platinum therapy. Methods We treated BLCA cells with PARPi (olaparib, niraparib, rucaparib, veliparib, or talazoparib) alone or as the combination of cisplatin with PARPi. We then measured their survival, proliferation, apoptosis, as well as their ability to form colonies. BLCA xenografts in male SCID mice were treated similarly, followed by the assessment of their growth, proliferation, and apoptosis. Results PARPi niraparib and talazoparib were effective in reducing BLCA cell survival as single agents. Combinations of Cisplatin with talazoparib and niraparib effectively reduced the survival of BLCA cells, while veliparib was not effective even at high concentrations. In vivo, the combinations of cisplatin with niraparib, rucaparib, or talazoparib reduced BLCA xenograft growth significantly. Conclusions We provide evidence that PARPi can be effective against BLCA as single agents or as combinatorial therapy with cisplatin.

Abstract
Radical cystectomy with bilateral pelvic lymph node dissection is the standard of care for muscle invasive bladder cancer (MIBC). The role of neoadjuvant and adjuvant therapy has evolved over the last 3–4 decades, and neoadjuvant chemotherapy (NACT) has now become the standard recommended treatment. However, there are many nuances to this and the utilization of chemotherapy has not been universal. The optimum chemotherapy regimen is still debated. Adjuvant radiation has a role in high-risk patients although not established and immunotherapy has shown promising results. We reviewed the evidence on NACT and adjuvant chemotherapy (ACT) regimens, NACT versus ACT, and the role of adjuvant radiotherapy and immunotherapy in MIBC.

Abstract
BACKGROUND: Radical cystectomy (RC) is the standard treatment for muscle invasive bladder cancer, but approximately half of all patients will ultimately succumb to disease progression despite apparent cure with extirpative surgery. Elderly patients are at especially high risk of advanced disease and may benefit from perioperative systemic therapy. OBJECTIVE: To assess the real-world benefit of adjuvant chemotherapy (AC) in patients ≥75 years old. METHODS: We retrospectively reviewed patients who underwent RC for non-metastatic urothelial carcinoma of the bladder (UCB) from 12 participating international medical institutions. Kaplan-Meier survival curves and Cox regression models were used to assess the association between age groups, administration of AC and oncological outcome parameters such as recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). RESULTS: 4,335 patients were included in the analyses, of which 820 (18.9%) were ≥75 years old. These elderly patients had a higher rate of adverse pathologic features. In an univariable subgroup analysis in patients ≥75 years with lymph node metastasis, 5-year OS was significantly higher in patients who had received AC (41% vs. 30.9%, p = 0.02). In a multivariable Cox model that was adjusted for several established outcome predictors, there was a significant favorable association between the administration of AC in elderly patients and OS, but no RFS or CSS. CONCLUSIONS: In this large observational study, the administration of AC was associated with improved OS, but not RFS or CSS, in elderly patients treated with RC for UCB. This is of clinical importance, as elderly patients are more likely to have adverse pathologic features and experience worse survival outcomes. Treatment of UCB should include both a multidisciplinary approach and a geriatric evaluation to identify patients who are most likely to tolerate and benefit from AC.

Abstract
INTRODUCTION A better understanding of the molecular profile of bladder tumours, the identification of novel therapeutic targets, and introduction of new drugs and has renewed research interest in the field of bladder cancer. We describe the design and setup of a Dutch Prospective Bladder Cancer Infrastructure (ProBCI) as a means to stimulate and accelerate clinically meaningful experimental and observational research. METHODS AND ANALYSIS ProBCI entails an open cohort of patients with bladder cancer in which the trials within cohorts (TwiCs) design can be embedded. Physicians in participating hospitals prospectively recruit invasive (≥T1) patients with bladder cancer on primary diagnosis for inclusion into the study. Extensive clinical data are collected and updated every 4 months, along with patient-reported outcomes and biomaterials. Informed consent includes participation in TwiCs studies and renewed contact for future studies. Consent for participation in questionnaires and molecular analyses that may yield incidental findings is optional. ETHICS AND DISSEMINATION The Dutch ProBCI is a unique effort to construct a nation-wide cohort of patients with bladder cancer including clinical data, patient-reported outcomes and biomaterial, to facilitate observational and experimental research. Data and materials are available for other research groups on request through www.probci.nl. Ethics approval was obtained from METC Utrecht (reference: NL70207.041.19).

Abstract
Background The benefit of adjuvant chemotherapy remains controversial in muscle-invasive bladder cancer (MIBC) after radical cystectomy. The present study’s primary objective was to construct a predictive tool for the reasonable application of adjuvant chemotherapy. Methods All of the patients analyzed in the present study were recruited from the Surveillance Epidemiology and End Results program between 2004 and 2015. Propensity score matching (PSM) was used to reduce inherent selection bias. Cox proportional hazards models were applied to identify the independent prognostic factors of overall survival (OS) and cancer-specific survival (CSS), which were further used to construct prognostic nomogram and risk stratification systems to predict survival outcomes. The prognostic nomogram’s performance was assessed by concordance index (C-index), receiver-operating characteristic (ROC) and calibration curves. Decision curve analysis (DCA) was performed to evaluate the clinical net benefit of the prognostic nomogram. Results A total of 6,384 patients with or without adjuvant chemotherapy were included after PSM. Several independent predictors for OS and CSS were identified and further applied to establish a nomogram for 3-, 5- and 10-year, respectively. The nomogram showed favorable discriminative ability for the prediction of OS and CSS, with a C-index of 0.709 [95% confidence interval (CI): 0.699–0.719] for OS and 0.728 (95% CI: 0.718–0.738) for CSS. ROC and calibration curves showed satisfactory consistency. The DCA revealed high clinical positive net benefits of the prognostic nomogram. The different risk stratification systems showed that adjuvant chemotherapy resulted in better OS (P<0.001) and CSS (P<0.001) than without adjuvant chemotherapy for high-risk patients; while the OS (P=0.350) and CSS (P=0.260) for low-risk patients were comparable. Conclusions We have constructed a predictive model and different risk stratifications for selecting a population that could benefit from postoperative adjuvant chemotherapy. Adjuvant chemotherapy was found to be beneficial for high-risk patients, while low-risk patients should be carefully monitored.

Abstract
BACKGROUND: Despite recent advances in the management of muscle-invasive bladder cancer (MIBC), treatment outcomes remain suboptimal, and variability exists across current practice patterns. OBJECTIVE: To promote standardization of care for MIBC in Canada by developing a consensus guidelines using a multidisciplinary, evidence-based, patient-centered approach who specialize in bladder cancer. METHODS: A comprehensive literature search of PubMed, Medline, and Embase was performed; and most recent guidelines from national and international organizations were reviewed. Recommendations were made based on best available evidence, and strength of recommendations were graded based on quality of the evidence. RESULTS: Overall, 17 recommendations were made covering a broad range of topics including pathology review, staging investigations, systemic therapy, local definitive therapy and surveillance. Of these, 10 (59% ) were level 1 or 2, 7 (41% ) were level 3 or 4 recommendations. There were 2 recommendations which did not reach full consensus, and were based on majority opinion. This guideline also provides guidance for the management of cisplatin-ineligible patients, variant histologies, and bladder-sparing trimodality therapy. Potential biomarkers, ongoing clinical trials, and future directions are highlighted. CONCLUSIONS: This guideline embodies the collaborative expertise from all disciplines involved, and provides guidance to further optimize and standardize the management of MIBC.

Abstract
Purpose Previous studies have noted increased utilization of perioperative chemotherapy over time. The goal of this study was to determine trends in perioperative chemotherapy use within a contemporary population. Materials and Methods The National Cancer Database was queried for patients diagnosed with cT2-4N0M0 urothelial muscle invasive bladder cancer from 2011 to 2015 and underwent subsequent radical cystectomy. We retrospectively analyzed factors associated with perioperative chemotherapy and evaluated overall treatment trends in the use of neoadjuvant and adjuvant chemotherapy. Linear regression, logistic regression, Cox regression, and Kaplan–Meier analysis were performed. Results In total, 7,101 patients met inclusion criteria for analysis. The use of perioperative chemotherapy increased from 46.4% in 2011 to 57.2% in 2015 (p=0.003). Neoadjuvant chemotherapy use increased from 22.9% to 32.3% (p=0.007) over the time period analyzed, while adjuvant chemotherapy use experienced no significant change (23.5% to 24.9%, p=0.182). Logistic regression demonstrated that increased age and Charlson Comorbidity Index were predictors of not receiving chemotherapy (p<0.05), while those with increasing T stage, income above $48,000, and insurance other than Medicaid or Medicare were more likely to receive perioperative chemotherapy (p<0.05). Kaplan–Meier analysis revealed patients receiving neoadjuvant chemotherapy had the best 5-year overall survival at 48.3% compared to adjuvant chemotherapy (42.6%) or no chemotherapy (37.8%) (p<0.001). Conclusions The increasing use of perioperative chemotherapy noted in prior studies has continued through 2015. Neoadjuvant chemotherapy appears to drive this increase while adjuvant chemotherapy utilization remains unchanged. Clinical and socioeconomic factors affect utilization of perioperative chemotherapy.

Abstract
BACKGROUND We use observational methods to compare impact of perioperative chemotherapy timing (ie, neoadjuvant and adjuvant) on overall survival (OS) in muscle-invasive bladder cancer because there is no head-to-head randomized trial, and patient factors may influence decision-making. PATIENTS AND METHODS Using Surveillance, Epidemiology, and End Results-Medicare data, we identified patients receiving cystectomy for muscle-invasive bladder cancer diagnosed between 2004 and 2013. Patients were classified as receiving neoadjuvant or adjuvant chemotherapy. Propensity of receiving neoadjuvant chemotherapy was determined using gradient boosted models. Inverse probability of treatment weighted survival curves were adjusted for 13 demographic, socioeconomic, temporal, and oncologic covariates. RESULTS We identified 1342 patients who received neoadjuvant (n = 676) or adjuvant chemotherapy (n = 666) with a median follow-up of 23 months (interquartile range, 9-55 months). Inverse probability of treatment weighted adjustment allows comparison of the groups head-to-head as well as counterfactual scenarios (eg, effect if those getting one treatment were to receive the other). The average treatment effect (ie, "head-to-head" comparison) of adjuvant compared with neoadjuvant on OS was not significant (hazard ratio, 1.14; 95% confidence interval, 0.99-1.31). However, the average treatment effect of the treated (ie, the effect if the neoadjuvant patients were to receive adjuvant instead) was associated with a 33% increase in risk of mortality if they were given adjuvant therapy instead (hazard ratio, 1.33; 95% confidence interval, 1.12-1.57). CONCLUSION Significant treatment selection bias was noted in peri-cystectomy timing, which limits the ability to discriminate differential efficacy of these 2 approaches with observational data. However, patients with higher propensity to receive neoadjuvant therapy were predicted to have increased OS with approach, in keeping with existing paradigms from trial data.

Abstract
INTRODUCTION Contemporary guidelines recommend cystectomy with neoadjuvant or adjuvant cisplatin-based chemotherapy given with curative intent for patients with resectable muscle-invasive bladder cancer (MIBC). However, rates and appropriateness of perioperative chemotherapy utilization remain unclear. We therefore sought to characterize use of perioperative chemotherapy in older radical cystectomy MIBC patients and examine factors associated with use. METHODS Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified patients with MIBC diagnosed between 2004 and 2013 and treated with radical cystectomy. We classified patients into 3 treatment groups: cystectomy alone, neoadjuvant, or adjuvant chemotherapy. Chemotherapy was classified by regimen. We then fit a multinomial multivariable logistic regression model to assess association between patient factors with the receipt of each treatment. RESULTS We identified 3,826 eligible patients. The majority (484; 65%) received cystectomy alone. Neoadjuvant (676; 18% overall, 69% cisplatin-based), and adjuvant chemotherapy (666, 17% overall, 55% cisplatin-based) were used in similar proportions of cystectomy patients. Over the study period, the odds of receiving adjuvant chemotherapy decreased by 7.5%, whereas neoadjuvant therapy increased by 27.5% (both P < 0.001). There was an increase in use of cisplatin-based regimens in the neoadjuvant setting (35 to 72%, P < 0.001), but not the adjuvant setting. Female gender, lower comorbidity, married status, and lower stage disease were associated with greater odds of receiving neoadjuvant chemotherapy (all P < 0.05). CONCLUSION From 2004 to 2013 use of neoadjuvant chemotherapy for MIBC increased while use of adjuvant chemotherapy decreased. Future studies examining barriers to appropriate chemotherapy use, and the comparative effectiveness of neoadjuvant versus adjuvant chemotherapy are warranted.

Abstract
Purpose We purposed to assess the effects of adjuvant chemotherapy (ACH) on survival outcomes in patients with locally advanced muscle-invasive bladder cancer (MIBC) who are treated with radical cystectomy (RC). Materials and Methods Literature search was conducted in PubMed, Embase, and Cochrane library databases for all articles that were published until February 2018. Systematic review and meta-analysis were performed by pooling the randomized controlled trials (RCTs) that compared patients with locally advanced MIBC who received ACH after RC to those who underwent cystectomy alone. Endpoints were progression free survival (PFS) and overall survival (OS). Results Four RCTs with a total of 490 patients were selected for the analysis. These four trials included patients with locally advanced MIBC. Pooled HRs for PFS and OS across the studies were 0.48 (95% confidence interval [CI], 0.39–0.60; p<0.00001) and 0.63 (95% CI, 0.48–0.83; p=0.0009), respectively. Absolute increases in PFS and OS for locally advanced MIBC were 17% and 10%, respectively (i.e., equivalent to numbers needed to treat of 5.9 and 10). Conclusions ACH following RC may improve the survival outcomes of locally advanced MIBC patients. Beneficial effect of ACH might be more marked in patients with locally advanced MIBC when comparing the previously reported meta-analysis with all MIBC patients.

Clinical efficacy and mechanism of Pralatrexate combined with Palbociclib Isethionate in treatment of bladder cancer patients. Oncol Lett 2019; 17:201-208.

Abstract
The clinical efficacy and mechanism of Pralatrexate (PTX) combined with Palbociclib Isethionate (PAL) in the treatment of bladder cancer patients was investigated. A retrospective analysis of medical records of 82 bladder cancer patients admitted to Shengjing Hospital of China Medical University from February 2015 to February 2018 was performed. Patients treated with PTX combined with PAL served as study group (42 cases) and patients with conventional GC (gemcitabine plus cisplatin) chemotherapy regimen were the control group (40 cases). Changes in liver function indexes before and after treatment were observed, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin (TBil). RT-qPCR was used for detection of relative expression levels of serum dihydrofolate reductase (DHFR) and vascular endothelial growth factor (VEGF) before and after treatment in the two groups. The clinical efficacy after treatment and adverse reactions during treatment were observed in the two groups. There was no significant difference in the clinical remission rate (RR) nor in the serum ALT, AST, ALP and TBil levels between the study and the control groups (P>0.05). Concentrations of serum ALT, AST, ALP and TBil were significantly higher than those before treatment in both groups (P<0.05). Serum ALT, AST, ALP and TBil concentrations in study group were significantly lower than those in control group (P<0.05). There was no significant difference in the incidence of thrombocytopenia and leukopenia between the two groups (P>0.05). There was no significant difference in relative expression levels of serum DHFR mRNA and VEGF mRNA before treatment between the study and control groups (P>0.05). Those after treatment were significantly lower than those before treatment in both groups (P<0.05), and those after treatment in study group were significantly lower than those in control group (P<0.05). PTX combined with PAL can reduce adverse reactions of nausea and vomiting and liver function impairment during treatment and suppress tumor neovascularization. This is achieved possibly by inhibiting expression levels of DHFR and VEGF, thereby killing cancer cells. PTX combined with PAL may become a new method for the treatment of bladder cancer patients. DHFR and VEGF are expected to become novel therapeutic targets for the treatment of bladder cancer.

Abstract
INTRODUCTION In patients with muscle invasive or Bacillus Calmette-Guérin refractory urothelial carcinoma of the urinary bladder (UCUB) radical cystectomy represents the standard of care. However, a proportion of patients experience disease progression, local recurrence and/or metastatic disease. Areas covered: This review provides an overview of available therapeutic strategies after radical cystectomy and examines ongoing clinical trials including cytotoxic chemotherapy and immunotherapy. Expert commentary: Cytotoxic chemotherapy offers limited benefit in UCUB patients. However, the recent introduction of immunotherapy provides new hope for durable responses or possibly complete cures.
