Overview
Malignant neoplasm of the urinary bladder, commonly known as bladder cancer, primarily involves transitional cell carcinoma (TCC) and is characterized by its potential to invade deeply and metastasize. 2Diagnosis
Endoscopic evaluation: Essential for initial visualization and biopsy.
Cytology: Urine cytology can detect malignant cells but has limitations in sensitivity.
Imaging: CT or MRI for staging and assessing extent of disease.
Nuclear medicine scans: Technetium-99-labeled albumin scans may aid in assessing extent of certain bladder lesions, though primarily relevant for benign conditions like cavernous hemangioma 1.Management
Transurethral resection (TURBT): Primary surgical approach for localized disease.
Intravesical chemotherapy/immunotherapy: Post-TURBT to reduce recurrence, e.g., BCG (Bacillus Calmette-Guérin) therapy.
Systemic chemotherapy: For advanced or metastatic disease, regimens include gemcitabine and cisplatin 2.
Radical cystectomy: Indicated for muscle-invasive disease or recurrence post-TURBT.Special Populations
Pregnancy: Limited data; management typically deferred until postpartum 2.
Pediatrics: Rare; management guided by adult protocols with caution 2.
Elderly: Consider comorbidities and functional status; less aggressive approaches may be warranted 2.
Comorbidities: Presence of diabetes or chronic kidney disease may influence treatment choices and outcomes 2.Key Recommendations
Utilize TURBT as the primary diagnostic and therapeutic modality for non-metastatic bladder cancer (Evidence: Strong 2).
Implement intravesical BCG therapy post-TURBT to reduce recurrence rates in high-risk patients (Evidence: Moderate 2).
Consider radical cystectomy for patients with muscle-invasive bladder cancer to improve survival outcomes (Evidence: Strong 2).References
