MDCalc

Muscle-Invasive and Metastatic Bladder Cancer

Based on 2023 guidelines from the European Association of Urology.

Managing Risk

Prevention
Strong recommendation

Counsel patients to stop active and avoid passive smoking.

Strong recommendation

Inform workers in potentially hazardous workplaces of the potential carcinogenic effects
of a number of recognised substances, including duration of exposure and latency periods. Protective measures are recommended.

Strong recommendation

Do not prescribe pioglitazone to patients with active bladder cancer or a history of bladder
cancer.

Pathology

Biopsy
Strong recommendation

Record the depth of invasion for the entire specimen (categories pT2a and pT2b, pT3a and pT3b or pT4a and pT4b).

Strong recommendation

Record margins with special attention paid to the radial margin, prostate, ureter, urethra, peritoneal fat, uterus and vaginal vault.

Strong recommendation

Record the total number of lymph nodes (LNs), the number of positive LNs, and extranodal spread.

Strong recommendation

Record lymphovascular invasion.

Strong recommendation

Record the presence of carcinoma in situ.

Strong recommendation

Record the sampling sites as well as information on tumor size when providing specimens to the pathologist.

Strong recommendation

Describe all macroscopic features of the tumor (site, size, number, and appearance) and mucosal abnormalities during cystoscopy. Use a bladder diagram.

Frozen Section
Strong recommendation

Take a biopsy of the prostatic urethra in cases of bladder neck tumor, when bladder carcinoma in situ is present or suspected, when there is positive cytology without evidence of tumor in the bladder, or when abnormalities of the prostatic urethra are visible.

Strong recommendation

In men with a negative prostatic urethral biopsy undergoing subsequent orthotopic neobladder construction, an intra-operative frozen section can be omitted.

Strong recommendation

In men with a prior positive transurethral prostatic biopsy, subsequent orthotopic neobladder construction should not be denied a priori, unless an intra-operative frozen section of the distal urethral stump reveals malignancy at the level of urethral dissection.

Strong recommendation

In women undergoing subsequent orthotopic neobladder construction, obtain procedural information (including histological evaluation) of the bladder neck and urethral margin, either prior to, or at the time of cystectomy.

Report
Strong recommendation

In the pathology report, specify the grade, depth of tumor invasion, and whether the lamina propria and muscle tissue are present in the specimen.

Management

Imaging
Strong recommendation

If an MRI is performed for local staging of bladder cancer it should be done before TURBT.

Strong recommendation

In patients with confirmed muscle-invasive bladder cancer, use computed tomography (CT) of the chest, abdomen and pelvis for staging, including some form of CT urography with designated phases for optimal urothelial evaluation.

Strong recommendation

Use CT urography, unless it is contraindicated for reasons related to contrast administration or radiation dose; in that case use MRI.

Weak recommendation

Offer MRI to assess the response to systemic therapy, which aids in the selection of patients for radical treatment, surveillance, and bladder-sparing surgery.

Comorbidities
Strong recommendation

Base the decision on bladder-sparing treatment or radical cystectomy in older/frail patients with invasive bladder cancer on tumor stage and frailty.

Strong recommendation

Assess comorbidity by a validated score, such as the Charlson Comorbidity Index. The American Society of Anesthesiologists score should not be used in this setting.

Genetic Markers
Strong recommendation

Use susceptible FGFR3 alterations to select patients with unresectable or metastatic urothelial carcinoma for treatment with erdafitinib.

Cisplatin Therapy
Strong recommendation

If eligible for cisplatin-based chemotherapy, offer neoadjuvant cisplatin-based combination chemotherapy to patients with muscle-invasive bladder cancer (T2-T4a, cN0 M0).

Strong recommendation

Do not offer neoadjuvant cisplatin-containing combination chemotherapy to patients who are ineligible for cisplatin-based combination chemotherapy.

Strong recommendation

Only offer neoadjuvant immunotherapy with checkpoint inhibitors alone to patients within a clinical trial setting.

Radiotherapy
Strong recommendation

Do not offer pre-operative radiotherapy (RT) for operable muscle-invasive bladder cancer since it will not improve survival.

Weak recommendation

Adjuvant RT can be offered following RC (pT3b-4 or positive nodes or positive margins) to improve loco-regional relapse free survival, but not overall survival.

Strong recommendation

Do not offer radiotherapy alone as primary therapy for localized bladder cancer.

Sexual Preserving Therapy - Men
Strong recommendation

Only offer sexual-preserving techniques to eligible men who are highly motivated to preserve their sexual function.

Strong recommendation

Select patients based on: organ-confined disease and absence of any kind of tumor at the level of the prostate, prostatic urethra or bladder neck.

Sexual Preserving Therapy - Women
Strong recommendation

Perform sexual organ-preserving techniques in eligible women. Select patients based on absence of tumor in the area to be preserved to avoid positive soft tissue margins.

Robotic-Assisted Laparoscopic Cystectomy
Strong recommendation

Inform the patient of the advantages and disadvantages of open radical cystectomy (ORC) and robot-assisted radical cystectomy (RARC) to allow selection of the proper procedure.

Strong recommendation

Select experienced centers, not specific techniques, both for RARC and ORC.

Radical Cystectomy and Urinary Diversion
Strong recommendation

Offer radical cystectomy (RC) to patients with T2-T4a, N0M0 disease or very high-risk nonmuscle-invasive bladder cancer.

Strong recommendation

Do not delay RC for >3 months as it increases the risk of progression and cancer-specific mortality, unless the patient receives neoadjuvant chemotherapy.

Strong recommendation

Perform a lymph node dissection as an integral part of RC.

Strong recommendation

Perform a standard LND, as an extended LND does not improve survival and increases the risk of morbidity.

Strong recommendation

Perform at least 20 RCs per hospital/per year.

Strong recommendation

Before RC, fully inform the patient about the benefits and potential risks of all possible alternatives. The final decision should be based on a balanced discussion between the patient and the surgeon.

Strong recommendation

Do not offer an orthotopic bladder substitute diversion to patients who have an invasive tumor in the urethra or at the level of urethral dissection.

Strong recommendation

Do not offer pre-operative bowel preparation.

Strong recommendation

Employ "Fast track" measurements to reduce the time to bowel recovery.

Strong recommendation

Offer pharmacological VTE prophylaxis, such as low-molecular-weight heparin to RC patients, starting the first day post-surgery, for a period of at least four weeks.

Palliative and Salvage Cystectomy
Weak recommendation

Offer radical cystectomy as a palliative treatment to patients with locally-advanced tumors (T4b).

Weak recommendation

Offer palliative cystectomy to patients with symptoms if control is not possible by less invasive methods.

Weak recommendation

Offer salvage cystectomy to patients with muscle-invasive bladder cancer after TMT.

Transurethral Resection
Strong recommendation

Do not offer transurethral resection of bladder tumor alone as a curative treatment option as most patients will not benefit.

Chemotherapy
Strong recommendation

Do not offer chemotherapy alone as primary therapy for localized bladder cancer.

Trimodality Bladder-Preserving Treatment
Strong recommendation

Offer radical cystectomy or trimodality bladder-preserving treatments (TMT) as primary curative option for eligible patients since they are more effective than radiotherapy alone.

Strong recommendation

Manage all patients who are candidates for TMT in a multidisciplinary team setting. The choice of treatment modality should be made through a shared-decision making process.

Strong recommendation

Advise patients who are candidates for TMT that life-long bladder monitoring is essential.

Adjuvant Therapy
Strong recommendation

Offer adjuvant cisplatin-based combination chemotherapy to patients with pT3/4 and/or pN+ disease if no neoadjuvant chemotherapy has been given.

Strong recommendation

Offer adjuvant nivolumab to selected patients with pT3/4 and/or pN+ disease not eligible for, or who declined, adjuvant cisplatin-based chemotherapy (FDA approval irrespective of PD-L1 status, EMA approval only for PD-L1 tumor cell expression ≥ 1%).

Combination Therapy - 1st line
Strong recommendation

Use antibody drug conjugate enfortumab vedotin (EV) in combination with checkpoint inhibitor (CPI) pembrolizumab.

Strong recommendation

If contraindications for EV or EV not available: Offer platinum-containing combination chemotherapy (cisplatin or carboplatin plus gemcitabine) followed by maintenance treatment with CPI avelumab in patients with at least stable disease on chemotherapy.

Strong recommendation

If contraindications for EV (or EV not available) and cisplatin-eligible: Consider cisplatin/gemcitabine in combination with CPI nivolumab.

Strong recommendation

If contraindications for EV and checkpoint inhibitor therapy: Use platinum-containing combination chemotherapy (cisplatin or carboplatin plus gemcitabine).

1st line Therapy if not cisplatin eligible
Weak recommendation

Consider single agent CPI pembrolizumab or atezolizumab in case of high PD-1 expression.

2nd line Therapy - After prior EV + CPI
Weak recommendation

Offer platinum-containing combination chemotherapy (cisplatin or carboplatin plus gemcitabine).

Weak recommendation

If actionable fibroblast growth factor receptor (FGFR) alterations: offer erdafitinib.

Weak recommendation

Consider antibody drug conjugate Trastuzumab deruxtecan in case of HER2 over expression (IHC 3+).

Weak recommendation

Consider single agent chemotherapy (docetaxel, paclitaxel, vinflunine).

2nd line Therapy - After prior platinun-based chemotherapy +/- CPI
Strong recommendation

Offer antibody drug conjugate enfortumab vedotin.

Strong recommendation

If actionable FGFR alterations and prior CPI: offer erdafitinib.

Strong recommendation

If no prior CPI: offer pembrolizumab.

Weak recommendation

Consider single agent chemotherapy (docetaxel, paclitaxel, vinflunine).

Further Therapy after EV, CPI, platinum-based therapy
Strong recommendation

General statement: Offer treatment in clinical trials. Consider best supportive care alone if patient is not a candidate for further cancer-specific systemic therapy.

Strong recommendation

If actionable FGFR alterations: offer erdafitinib.

Follow-up

Quality of Life
Strong recommendation

Use validated questionnaires to assess health-related quality of life in patients with muscle invasive bladder cancer, both at baseline and post-treatment.

Strong recommendation

Discuss the type of urinary diversion taking into account patient preference, existing comorbidities, tumor variables, and coping abilities.

Local Recurrence
Strong recommendation

Offer radiotherapy, chemotherapy and possibly surgery as options for treatment, either alone or in combination.

Distant Recurrence
Strong recommendation

Offer chemotherapy as the first option, and consider metastasectomy or radiotherapy in case of unique metastasis site.

Upper Urinary Tract Recurrence
Strong recommendation

See EAU Guidelines on Upper Urinary Tract Urothelial Carcinomas.

Secondary Urethral Tumor
Strong recommendation

See EAU Guidelines on Primary Urethral Carcinoma.
