Bladder cancer

Definition
BC is a malignancy that originates in the epithelial lining of the bladder.
1
Pathophysiology
The pathophysiology of BC involves abnormal and uncontrolled growth of cells in the bladder lining leading to the formation of a tumor, which can be noninvasive or invasive.
1
Epidemiology
The prevalence of BC worldwide is estimated at 35.05 per 100,000 population.
2
Disease course
Clinically, BC often presents with gross or microscopic hematuria, urinary urgency, and pelvic pain. Diagnosis is typically made through cystoscopy and upper tract imaging.
1
Prognosis and risk of recurrence
The prognosis of BC is influenced by several factors. The stage of the cancer at diagnosis is a key determinant, with each successive stage carrying a worse prognosis.
3
Key sources
The following summarized guidelines for the evaluation and management of bladder cancer are prepared by our editorial team based on guidelines from the European Association of Urology (EAU 2023; 2021), the European Society of Medical Oncology (ESMO 2022; 2014), the American Urological Association (AUA/SUO/ASTRO/ASCO 2017), the American Urological Association (AUA/SUO 2016), and the U.S. Preventive Services Task Force (USPSTF 2011).

Guidelines

1.Screening and diagnosis

Indications for screening: as per EAU 2023 guidelines, take into account the increased risk of developing BC in patients undergoing external-beam radiation therapy, brachytherapy, or a combination of those, during follow-up. Follow-up closely patients treated with radiation at a young age, as they are at the greatest risk and BC requires time to develop.

2.Classification and risk stratification

Risk factors: recognize that there are several risk factors connected with the risk of BC, with tobacco smoking as the most important one.

3.Diagnostic investigations

History and physical examination: use validated questionnaires to assess health-related QoL in patients with muscle-invasive BC, both at baseline and post-treatment.

4.Diagnostic procedures

Cystoscopy and ureteroscopy
As per EAU 2023 guidelines:
Perform cystoscopy for the diagnosis of BC.
A
Describe all macroscopic features of the tumor (site, size, number, and appearance) and mucosal abnormalities during cystoscopy. Use a bladder diagram.

5.Medical management

Management of non-muscle-invasive cancer, general principles: follow a risk-stratified approach with transurethral resection of the bladder tumor and intravesical chemotherapy or BCG in intermediate- and high-risk patients with non-muscle-invasive BC.

General counseling: as per EAU 2023 guidelines, inform patients of the advantages and disadvantages of open radical cystectomy and robot-assisted radical cystectomy to allow selection of the proper procedure.

11.Preventative measures

Avoidance of carcinogenic substances
Inform workers in potentially hazardous workplaces of the potential carcinogenic effects of a number of recognized substances, including duration of exposure and latency periods. Advise protective measures.
A
Do not prescribe pioglitazone in patients with active BC or a history of BC.

12.Follow-up and surveillance

Surveillance, non-muscle-invasive cancer, EAU: use the 2006 EORTC scoring model to predict the risk of tumor recurrence in individual patients not treated with BCG.
