Abstract
OBJECTIVE The aim of this review is to summarize the current evidence and future perspectives of bladder-sparing treatment for MIBC. METHODS A non-systematic literature search in Medline/Pubmed was performed in October 2023 with the following keywords "bladder cancer", "bladder-sparing", "trimodal therapy", "chemoradiation", "biomarkers", "immunotherapy", "neoadjuvant chemotherapy", "radiotherapy". RESULTS Urology guidelines recommend radical cystectomy as the standard curative treatment for muscle-invasive urothelial bladder cancer, reserving radiotherapy for patients who are unfit or who want to preserve their bladder. Given the morbidity and mortality of cystectomy and its impact on quality of life and bladder function, modern oncologic therapies are increasingly oriented toward organ preservation and maximizing functional outcomes while maintaining treatment efficacy. Trimodal therapy, which incorporates maximal transurethral resection followed by radiotherapy with concurrent radiosensitizing chemotherapy, is an effective regimen for bladder function preservation in well-selected patients. Despite the absence of comparative data from randomized trials, the two approaches seem to provide comparable oncologic outcomes. Studies are evaluating the expansion of eligibility criteria for trimodal therapy, the optimization of radiotherapy and immunotherapy delivery to further improve outcomes, and the validation of biomarkers to guide bladder preservation. CONCLUSIONS Trimodal therapy has shown acceptable outcomes for bladder preservation; therefore, it provides a valid treatment option in well-selected patients.

Abstract
Over the last two to three decades the non-surgical curative management of bladder cancer has significantly progressed. Increasing evidence supports the use of bladder preservation as an alternative to radical cystectomy (RC) for localised muscle-invasive bladder cancer (MIBC). Radiosensitisation with chemotherapy or hypoxia modification improves the efficacy of radiotherapy. Systemic treatments play an important role in the management of localised MIBC with the benefit of neoadjuvant chemotherapy prior to radical treatment well established. The use of immune checkpoint inhibitors (ICIs) in the radical treatment of bladder cancer, their safe combination with radical radiotherapy regimens and whether the addition of ICIs improve rates of cure are outstanding questions beginning to be answered by ongoing clinical trials. In this narrative review, we discuss the current evidence for bladder preservation and the role of systemic treatments for localised MIBC.

Abstract
Metastatic bladder and renal cancers account respectively for 2.1% and 1.8% of cancer deaths worldwide. The advent of immune checkpoint inhibitors has revolutionized the management of metastatic disease, by demonstrating considerable improvements in overall survival. However, despite initial sensitivity to immune checkpoint inhibitors for most patients, both bladder and renal cancer are associated with short progression-free survival and overall survival, raising the need for further strategies to improve their efficacy. Combining systemic therapies with local approaches is a longstanding concept in urological oncology, in clinical settings including both oligometastatic and polymetastatic disease. Radiation therapy has been increasingly studied with either cytoreductive, consolidative, ablative or immune boosting purposes, but the long-term impact of this strategy remains unclear. This review intends to address the impact of radiation therapy with either curative or palliative intent, for synchronous de novo metastatic bladder and renal cancers.

European Association of Urology Guidelines on Muscle-invasive and Metastatic Bladder Cancer: Summary of the 2023 Guidelines. Eur Urol 2024; 85:17-31. [PMID: 37858453 DOI: 10.1016/j.eururo.2023.08.016] [Citation(s) in RCA: 44] [Impact Index Per Article: 44.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Accepted: 08/18/2023] [Indexed: 10/21/2023]
Abstract
CONTEXT We present an overview of the updated 2023 European Association of Urology (EAU) guidelines for muscle-invasive and metastatic bladder cancer (MMIBC). OBJECTIVE To provide practical evidence-based recommendations and consensus statements on the clinical management of MMIBC with a focus on diagnosis and treatment. EVIDENCE ACQUISITION A broad and comprehensive scoping exercise covering all areas of the MMIBC guidelines has been performed annually since 2017. Searches cover the Medline, EMBASE, and Cochrane Libraries databases for yearly guideline updates. A level of evidence and strength of recommendation are assigned. The evidence cutoff date for the 2023 MIBC guidelines was May 4, 2022. EVIDENCE SYNTHESIS Patients should be counselled regarding risk factors for bladder cancer. Pathologists should describe tumour and lymph nodes in detail, including the presence of histological subtypes. The importance of the presence or absence of urothelial carcinoma (UC) in the prostatic urethra is emphasised. Magnetic resonance imaging (MRI) of the bladder is superior to computed tomography (CT) for disease staging, specifically in differentiating T1 from T2 disease, and may lead to a change in treatment approach in patients at high risk of an invasive tumour. Imaging of the upper urinary tract, lymph nodes, and distant metastasis is performed with CT or MRI; the additional value of flurodeoxyglucose positron emission tomography/CT still needs to be determined. Frail and comorbid patients should be evaluated by a multidisciplinary team. Postoperative histology remains the most important prognostic variable, while circulating tumour DNA appears to be an interesting predictive marker. Neoadjuvant systemic therapy remains cisplatin-based. In motivated and selected women and men, sexual organ-preserving cystectomy results in better functional outcomes without compromising oncological outcomes. Robotic and open cystectomy have comparable outcomes and should be combined with (extended) lymph node dissection. The diversion type is an individual choice after taking patient and tumour characteristics into account. Radical cystectomy remains a highly complex procedure with considerable morbidity and risk of mortality, although lower rates are observed for higher hospital volumes (>20 cases/yr). With proper patient selection, trimodal therapy (chemoradiation) has comparable outcomes to radical cystectomy. Adjuvant chemotherapy after surgery improves disease-specific survival and overall survival (OS) in patients with high-risk disease who did not receive neoadjuvant treatment, and is strongly recommended. There is a weak recommendation for adjuvant nivolumab, as OS data are not yet available. Health-related quality of life should be assessed using validated questionnaires at baseline and after treatment. Surveillance is needed to monitor for recurrent cancer and functional outcomes. Recurrences detected on follow-up seem to have better prognosis than symptomatic recurrences. CONCLUSIONS This summary of the 2023 EAU guidelines provides updated information on the diagnosis and treatment of MMIBC for incorporation into clinical practice. PATIENT SUMMARY The European Association of Urology guidelines panel on muscle-invasive and metastatic bladder cancer has released an updated version of the guideline containing information on diagnosis and treatment of this disease. Recommendations are based on studies published up to May 4, 2022. Surgical removal of the bladder and bladder preservation are discussed, as well as updates on the use of chemotherapy and immunotherapy in localised and metastatic disease.

Hypofractionated Radiation Therapy (Hypo-RT) for the Treatment of Localized Bladder Cancer. Bladder Cancer 2023; 9:141-150. [PMID: 38993294 PMCID: PMC11181850 DOI: 10.3233/blc-220121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Accepted: 04/25/2023] [Indexed: 07/13/2024]
Abstract
BACKGROUND Various radiotherapeutic regimens are used in the treatment of bladder cancer. OBJECTIVE We aimed to evaluate early toxicity and outcomes associated with hypofractionated radiation therapy (Hypo-RT), 55Gy in 20 fractions. MATERIAL AND METHODS We identified 40 patients who received definitive Hypo-RT for localized bladder cancer. Most patients were men (62.5%), elderly (median age 82), had high Charlson Comorbidity Index score (median 7, range 4-9) and were nonsurgical candidates (80%). Sixty-eight percent had a macroscopically complete transurethral resection of bladder tumor (TURBT) and 33 patients (82.5%) received concurrent chemotherapy. Acute (< =3mo) and late (>3mo) toxicities were assessed according to CTCAE v4.0. Survival outcomes were estimated using the Kaplan-Meier method. Median follow up after Hypo-RT was 32 months (95% CI: 28-49 months). RESULTS Overall rates of acute grade 2 genitourinary (GU) and gastrointestinal (GI) toxicities were 40% each, most commonly urinary frequency and diarrhea. Two cases of acute grade 3 GU/GI toxicity occurred. Late grade 2+ toxicity occurred in 3 patients (7.5%): 2 grade 2 GU and 1 grade 3 GI. Seventy-seven percent achieved a complete response (CR). Six patients (20%) developed disease recurrence at a median time of 9.1 months. The estimated 2-year DFS and 2-year DSS rate were 59% (95% CI, 45-78%) and 78% (95% CI, 65-93%), respectively. Receipt of concurrent chemotherapy (p = 0.003) and achieving a CR (p = 0.018) were univariably associated with improved DSS. Tis component was associated with worse DSS (p = 0.015). CONCLUSION Hypo-RT had a favorable toxicity profile and encouraging cancer control outcomes in this mostly elderly and frail patient cohort.

Abstract
PURPOSE OF REVIEW The authors aimed to highlight trends in, and evidence underlying the use of highly conformal radiotherapy (RT) techniques in conventional nonstereotactic palliative RT. The authors reviewed palliative-intent and curative-intent studies relevant to the use of intensity-modulated radiation therapy (IMRT) for the delivery of nonstereotactic conventional regimens to the brain, head and neck, thorax, abdomen and pelvis, and bone metastases. RECENT FINDINGS The use of IMRT has become standard with certain indications for brain metastases such as hippocampus-avoiding/limiting whole brain RT. IMRT in the treatment of bone metastases is increasing at many institutions despite limited data comparing its effectiveness with that of fluoroscopy-based and three-dimensional conformal radiation therapy techniques. There is scant data describing the use of IMRT for palliation in other extracranial anatomic sites; guidance for its use in these settings must be gleaned almost exclusively from curative-intent randomized trials, consensus recommendations and contouring atlases. SUMMARY Consistent with historical technology shifts in RT practice, the uptake of highly conformal techniques such as IMRT for conventional palliative RT will likely outpace rigorous evaluations of their advantages and disadvantages relative to simpler techniques. Opportunities exist in virtually all anatomic sites for observational and randomized studies to evaluate the clinical impacts of these modern techniques in the palliative setting.

Abstract
INTRODUCTION Use of hypofractionated radiation (HFRT) and intensity-modulated radiation (IMRT) for organ preservation in bladder cancer is controversial and highly variable. We investigated practice patterns, trends, and predictors of HFRT and IMRT. PATIENTS AND METHODS The National Cancer Database was queried for patients with muscle-invasive, non-metastatic urothelial bladder cancer, treated with definitive (chemo)radiotherapy between 2004 and 2017. HFRT was defined as 50 to 60 Gy at >2 Gy/fraction. Multivariable logistic regression was used to identify predictors of receiving HFRT or IMRT. Multivariable Cox regression was used to model overall survival (OS), adjusting for potential confounders such as age, comorbidity, and chemotherapy. RESULTS Of 5132 patients identified, 490 (9.5%) received HFRT, and only 334 (6.5%) received ≥2.5 Gy/fraction. HFRT patients were significantly older, less fit, and less likely to receive chemotherapy relative to CFRT, even after controlling for age and comorbidity (adjusted odds ratio 0.36, 95% confidence interval [CI] 0.29-0.45, P < .0001). Utilization of HFRT and IMRT increased over time (P < .0001), reaching 22.5% and 47.7%, respectively, by 2017. Among patients treated with CFRT, OS was similar with or without IMRT (P = .46). Among patients treated with HFRT, IMRT was associated with increased survival (3-year OS 35% vs. 24%, P = .03), which persisted in multivariable analysis (adjusted hazard ratio 0.71, 95% CI 0.52-0.98, P = .04). CONCLUSION HFRT is largely underutilized, being primarily reserved for older, frailer patients. Chemotherapy is significantly underused with HFRT relative to CFRT. IMRT is used frequently and was associated with equivalent or modestly increased overall survival.

Abstract
Bladder preservation with trimodality treatment (TMT) is an alternative strategy to radical cystectomy (RC) for the management of localised muscle invasive bladder cancer (MIBC). TMT comprises of transurethral resection of the bladder tumour (TURBT) followed by radiotherapy with concurrent radiosensitisation. TMT studies have shown neo-adjuvant chemotherapy with cisplatin-based regimens is often given to further improve survival outcomes. A hypofractionated radiotherapy regimen is preferable due to its non-inferiority in local control and late toxicities. Radiosensitisation can comprise concurrent chemotherapy (with gemcitabine, cisplatin or combination fluorouracil and mitomycin), CON (carbogen and nicotinomide) or hyperthermic treatment. Radiotherapy techniques are continuously improving and becoming more personalised. As the bladder is a mobile structure subject to volumetric changes from filling, an adaptive approach can optimise bladder coverage and reduce dose to normal tissue. Adaptive radiotherapy (ART) is an evolving field that aims to overcome this. Improved knowledge of tumour biology and advances in imaging techniques aims to further optimise and personalise treatment.

Abstract
PURPOSE Curative radio-chemotherapy is recognized as a standard treatment option for muscle-invasive bladder cancer (MIBC). Nevertheless, the technical aspects for MIBC radiotherapy are heterogeneous with a lack of practical recommendations. METHODS AND MATERIALS In 2018, a workshop identified the need for two cooperative groups to develop consistent, evidence-based guidelines for irradiation technique in the delivery of curative radiotherapy. Two radiation oncologists performed a review of the literature addressing several topics relative to radical bladder radiotherapy: planning computed tomography acquisition, target volume delineation, radiation schedules (total dose and fractionation) and dose delivery (including radiotherapy techniques, image-guided radiotherapy (IGRT) and adaptive treatment modalities). Searches for original and review articles in the PubMed and Google Scholar databases were conducted from January 1990 until March 2020. During a meeting conducted in October 2020, results on 32 topics were presented and discussed with a working group involving 15 radiation oncologists, 3 urologists and one medical oncologist. We applied the American Urological Association guideline development's method to define a consensus strategy. RESULTS A consensus was obtained for all 34 except 4 items. The group did not obtain an agreement on CT enhancement added value for planning, PTV margins definition for empty bladder and full bladder protocols, and for pelvic lymph-nodes irradiation. High quality evidence was shown in 6 items; 8 items were considered as low quality of evidence. CONCLUSION The current recommendations propose a homogenized modality of treatment both for routine clinical practice and for future clinical trials, following the best evidence to date, analyzed with a robust methodology. The XXX group formulates practical guidelines for the implementation of innovative techniques such as adaptive radiotherapy.

Outcome of radiotherapy for invasive bladder cancer in older patients - not candidates for or decline cystectomy. Cancer Radiother 2020; 24:820-825. [PMID: 33172775 DOI: 10.1016/j.canrad.2020.04.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 04/04/2020] [Accepted: 04/09/2020] [Indexed: 11/20/2022]
Abstract
PURPOSE Retrospective study to assess the role of radiotherapy (RT) in bladder cancer (BC) in patients who decline cystectomy or for whom it was contraindicated, regarding BC related events. MATERIALS AND METHODS A cross-sectional study, of patients with BC treated with RT, with or without chemotherapy was carried out, during the period March 2005 to March 2017, excluding patients who performed cystectomy. BC-related events were defined as haematuria, episodes requiring intravesical irrigations or transurethral resection or admission in Urology Department caused by symptoms related to BC. RESULTS Fifty-eight patients were included, 44 men and 14 women, whose median age at diagnosis was 78.3 years. Nine patients were treated with a RT dose below 50Gy (20-45Gy), in relation with non-resectable disease, nodal involvement, presence of metastasis or poor performance status. Forty-nine patients were treated with a RT dose above 50Gy (maximum 60.4Gy). The median follow-up time was 24 months, with BC-specific survival at 1/5 years of 87.5%/0.0% and 83.1%/33.9% in the group treated with RT dose below 50Gy and above 50Gy, respectively. Results revealed that the number of events decreased significantly after RT for both groups. For the two groups, the median of events before RT was 2.0, decreasing for 1.0 after RT (RT dose<50Gy: P=0.011; RT dose≥50Gy: P=0.026). CONCLUSION This therapeutic approach can have an important role in older patients with bladder cancer, in terms of reducing disease related events. Symptom control was significantly achieved in both therapeutic groups.
