bladder cancer therapy flowchart

Treatment Options of Superficial Bladder Cancer:

TURB with complete resection of the tumor, single shot Mitomycin after TURB. Repeat resection of the scar after 4–6 weeks is recommended for any tumor but small unilocular Ta low-grade. Regular follow-up depends on the risk classification according to table table simple risk stratification, EORTC risk classification 1 and tab. EORTC risk classification 2.

Endoscopically unmanageable tumor:

Radical cystectomy.

Adjuvant intravesical therapy:

With mitomycin C or BCG depending on the risk profile according to table simple risk stratification. Fluoroescence cystoscopy, repeat resection of the scar and quadrant biopsy is done after the first treatment cycle.

With a negative histology:

Intravesical maintenance therapy.

With a low-grade recurrence:

Further intravesical chemotherapy and repeat TURB.

With a high-grade recurrence:

Radical cystectomy.

Treatment Options of muscle-invasive bladder cancer (T2–4 M0):

Radical cystectomy. Consider neoadjuvant chemotherapy for advanced bladder cancer.

After cystectomy with R0, N0, M0:

Regular cancer follow-up.

After cystectomy with R1, N+ or ≥T3b:

Consider adjuvant chemotherapy or immunotherapy. Regular cancer follow-up.

Urothelial carcinoma of the prostate:

Radical cystectomy, orthotopic urinary diversion is not possible.

Alternatives to cystectomy:

Especially in patients with a high surgical risk.

≥T2 bladder carcinoma at the bladder dome:

Partial cystectomy with pelvic lymph node dissection.

Repeat radical TURB:

If a R0 resection is reached, close follow up with repeat biopsies.


Radical TURB with adjuvant radiochemotherapy.

Bladder carcinoma with distant metastases:

Cisplatin-containing chemotherapy or immunotherapy with checkpoint inhibitors.

Transurethral Resection of the Bladder (TURB)

Transurethral resection of the bladder (TURB) is the initial form of therapy for all bladder tumors. The depth of infiltration and histological differentiation can be diagnosed relatively accurately, and further therapeutic steps are planned depending on these results (see above). It is important to include bladder muscle in the resection specimen for accurate histopathological staging, there is a significant risk of understaging due to insufficient depth of resection. The aim of resection is the complete removal of the tumor manifestation, for this purpose the tumor is either resected in fractions (standard method) or dissected en bloc with tumor base from the bladder wall.

Repeat transurethral resection:

Patients with small, unilocular, noninvasive, and well-differentiated bladder carcinomas (Ta low-grade) are adequately treated with a single resection and can be followed with cystoscopies. Any other superficial bladder carcinoma with higher risk (large, multilocular, T1 or for high-grade tumors), a repeat resection of the scars within 6 weeks is indicated. For TaG3 or T1 tumors, the risk of residual tumor in the specimen of the repeat resection is up to 30–50%, and the repeat resection leads to a significant improvement of the recurrence rate.

En-bloc resection:

En-bloc resection is done with a monopolar hook, with the resection loop, or with laser technique. En bloc resection offers the advantage of reduced tumor cell seeding and improves pathologic examination; comparative studies are lacking.

Fluorescence Cystoscopy:

Fluorescence cystoscopy using blue light after intravesical application of 5-aminolevulinic acid (5-ALA) or hexaminolevulinate (HAL), leads to better detection of carcinoma of the urinary bladder, especially flat lesions such as CIS (Jocham et al., 2005). See also section diagnosis of bladder cancer for images and technique of fluorescence cystoscopy. Indications: high-grade tumor cells in urine cytology, in all patients with a history of multifocal or high-grade tumors.

Perioperative intravesical chemotherapy:

Early single-shot intravesical instillation of mitomycin C after TURB reduces recurrence rate by 40% (Sylvester et al., 2004). Dosage: 40 mg intravesical mitomycin C, exposure time 1–2 hours (no irrigation or gravity drainage). Contraindications: permanent postoperative bleeding, bladder perforation.

Intravesical Therapy

Intravesical therapy can safely reduce the risk of recurrence and progression of superficial bladder carcinomas. A simple risk assignment of recurrence and progression is possible with table simple risk stratification. More precisely, the probability of recurrence and progression can be determined using the EORTC risk classification (table EORTC risk classification 1 and table EORTC risk classification 2). If the risk of recurrence is low and the risk of progression is low, intravesical therapy is not recommended. For intermediate and high risk of recurrence or intermediate risk of progression, mitomycin C or BCG may be chosen as intravesical therapy. Intravesical therapy with BCG is more effective but also has significantly more side effects. If the risk of progression is high, BCG should be chosen as the more effective agent. In young patients, early cystectomy is a reasonable alternative to intravesical therapy.

Simple risk stratification of superficial bladder cancer using the pathology findings after TURB (Babjuk et al., 2008), as alternative to table table EORTC risk classification 1 and table EORTC risk classification 2.
Low risk First diagnosis of Ta low-grade tumor <3 cm
Intermediate risk Low or high risk criteria do not apply.
High risk T1 tumors, high-grade histology, CIS, multilocular recurrent low-grade tumors, tumor size > 3 cm.

EORTC risk classification: tumor size, number, recurrence rate, T stage, and grading can be used to determine the recurrence risk and progression risk of superficial bladder carcinoma (Sylvester et al., 2006a). The sum of the risk scores from this table is used in table EORTC risk classification 2 to calculate the recurrence and progression risk.

Intravesical Therapy with Bacillus Calmette-Guerin (BCG):

The attenuated strain of Mycobacterium bovis leads to a local inflammatory reaction, which has an anticarcinogenic effect.

Indications for BCG:

Intravesical immunotherapy to lower recurrence and progression of intermediate- and high-risk superficial bladder carcinoma, see table EORTC risk classification 1 and table EORTC risk classification 2. BCG immunotherapy is more effective than mitomycin~C instillation, disadvantageous is the high rate of side effects, see section pharmacology of BCG.

Dosage of BCG:

2×108 to 3×109 bacteria in 50 ml NaCl as intravesical instillation once weekly over 6 weeks. Recommended exposure time is two hours, the patient should drink little before instillation. After the six-week treatment cycle and six weeks off, a post-resection and quadrant biopsy should be performed. If intravesical chemotherapy is successful, maintenance therapy is reasonable: three instillations at weekly intervals at months 3, 6, 12, 18, 24, 30, and 36. In the case of high-grade recurrence, cystectomy should be sought; alternatively, a second cycle of BCG may be attempted if the surgical risk is high.

Side effects:

Intravesical administration of BCG often leads to local and sometimes to systemic side effects, which necessitate pausing or discontinuation of therapy, please see section pharmacology of BCG for management of side effects.

Treatment results:

In superficial high-grade cancer, a durable remission is achievable in approximately 50–70%. BCG reduces the risk of recurrence by approximately 50% compared to TURB alone.

Intravesical Therapy with Mitomycin C:

Intravesical chemotherapy with mitomycin C is better tolerated than intravesical BCG, it is a treatment option instead of BCG for tumors with intermediate risk of recurrence or progression, see table EORTC risk classification 1 and table EORTC risk classification 2. The efficacy of mitomycin C is lower than BCG and should not be recommended in patients with at high clinical risk.

Dosage of Mitomycin C:

20–40 mg of mitomycin C intravesically per week (6 instillations), then monthly administrations (11 instillations). See section mitomycin C for details on pharmacology and side effects.

Intravesical Therapy with Epirubicin or doxirubicin:

Epirubicin or doxirubicin are alternatives to BCG or mitomycin C for intravesical therapy in superficial high-risk bladder carcinoma. Mechanism of action of the anthracyclines: interaction with DNA and RNA leads to impairement of synthesis and strand breaks.

Radical Cystectomy for Bladder Cancer Treatment

Indications for cystectomy:

Surgical technique of cystectomy and urinary diversion:

The bladder is removed with safety distance and a pelvic lymphadenectomy is performed. In men, the specimen includes the bladder, prostate, seminal vesicles, both distal ureters, both ampulla vas deferens. In women, the specimen includes the bladder, both distal ureters, segments of the anterior vaginal wall, uterus, and depending on age the fallopian tubes and ovaries. If an orthotopic neobladder is not considered, the female urethra is also resected. See section cystectomy and urinary diversion for details.

Surgical modifications of cystectomy:

To avoid sexual side effects and to improve urinary incontinence, technical modifications have been published both in women (Koie et al., 2010) and in men (Mertens et al., 2014). In woman, preservation of the vaginal anterior wall and uterus improves sexual function and continence after surgery. In men, preservation of the prostatic capsule protects the urinary sphincter and cavernous nerves with improved continence and erectile function. Careful selection of patients depending on intravesical tumor growth is elementary for oncological success. Preoperative targeted biopsies of the trigonum and the prostatic urethra should be without tumor involvement.

Oncological results after cystectomy:

See section prognosis of bladder carcinoma.

Cystectomy and Neoadjuvant or Adjuvant Chemotherapy:

Several studies demonstrate prolonged survival with neoadjuvant as well as with adjuvant chemotherapy, meta-analyses found an improved five-year survival rate of 5–6% (Burdett et al., 2022). Indications are extravesical tumor growth or lymph node metastases diagnosed preoperatively on imaging or after surgery with the pathological examination, some authors recommend (neo)adjuvant therapy for every patient with muscle-invasive carcinoma.


2–4 cycles of MVAC or gemcitabine/cisplatin are administered before surgery, and further postoperative chemotherapy is decided upon on histology and response. Dosage for adjuvant chemotherapy are 4 cycles of MVAC or gemcitabine/cisplatin.

Adjuvant immunotherapy:

Adjuvant immunotherapy with nivolumab improves progression-free survival after cystectomy: 21 months (nivolumab) vs. 11 months (placebo) median progression-free survival (Bajorin et al., 2021). Nivolumab is approved in Europe since 2022 for adjuvant therapy in patients with a high risk of recurrence (pT3–4 or pTN+) and tumor cell PD-L1 expression ≥1%.

Adjuvant immunotherapy with atezolizumab failed to show improvement in progression-free survival (Bellmunt et al., 2021), and other checkpoint inhibitors are in clinical trials.

Neoadjuvant radiotherapy:

Neoadjuvant radiotherapy is not recommended before radical cystectomy, although individual studies have demonstrated a positive effect against local recurrence. Survival is determined by distant metastases which are not affected by neoadjuvant radiotherapy.

Partial Cystectomy

Partial cystectomy with pelvic lymphadenectomy is a therapeutic alternative to radical cystectomy for localized bladder carcinoma with muscle invasion, especially when localized at the bladder roof or with adequate distance from the ureteral orifices. Furthermore, urachal carcinoma and bladder diverticula carcinomas are well suited for partial cystectomy; this also applies to large superficial diverticula carcinoma. Disadvantage of partial cystectomy is the risk of intravesical recurrence and thus the need for regular cystoscopy and biopsies, two-stage radical cystectomy for tumor progression is necessary in up to 25%. The following conditions are recommended to achieve oncologic outcome comparable to radical treatment (Capitanio et al., 2009):

Bladder Preservation with Radiochemotherapy

Bladder preservation is possible with a combined therapy regimen: radical TURB is followed by radiotherapy and cisplatin-containing chemotherapy. In comparable tumor stages and patient selections, comparable results are reported to patients with radical cystectomy: five-year survival 48–63%, in 36–43% long-term survival with bladder preservation is reported.

Disadvantages include the high rate of side effects, the need for costly interdisciplinary treatment, and the high recurrence rate of superficial tumors with persistent need for cystoscopy and TURB. A clear advantage in quality of life seems more than questionable given the good functional results of the neobladder.
