Overview
Bladder cancer originates from the urothelium, the lining of the bladder.
Most cases are transitional cell carcinoma, presenting with painless hematuria.
Early detection and appropriate endoscopic or surgical treatment can lead to long-term cure, especially for non-muscle invasive disease.
Overview And Clinical Background
Epidemiology and etiology
Bladder cancer primarily affects older adults and is strongly associated with smoking and chemical exposure.
It is categorized into non-muscle invasive, muscle-invasive, and metastatic forms.
- Histology: Predominantly urothelial carcinoma; squamous and adenocarcinoma variants exist.
- Risk factors: Smoking, aromatic amine exposure, chronic infections.
- Prevention: Smoking cessation and regular screening for high-risk individuals.
Symptoms, Signs And Presentation
Classic presentation includes visible blood in urine without pain.
Some patients report frequency or urgency.
- Hematuria: Painless visible blood in urine is the hallmark sign.
- Irritative symptoms: Frequency, urgency, or dysuria may occur.
- Advanced disease: Pelvic pain, weight loss, or bone pain in metastasis.
Diagnosis Methods And Investigations
Endoscopy and imaging
Cystoscopy with biopsy confirms diagnosis.
Imaging assesses local invasion and metastasis.
- Cystoscopy: Direct visualization and biopsy of bladder lesions.
- Imaging: CT urogram or MRI to assess invasion and nodes.
- Urine cytology: Detects malignant cells in urine for high-grade disease.
Treatment Options And Surgical Techniques
Treatment varies by stage — endoscopic resection for superficial tumors, radical cystectomy for invasive disease, and intravesical therapy for recurrence prevention.
- TURBT: Transurethral resection of bladder tumor for diagnosis and initial treatment.
- Intravesical therapy: BCG or chemotherapy instillation to prevent recurrence.
- Cystectomy: Partial or radical bladder removal for invasive disease.
Recovery, Risks And Prognosis
Non-muscle invasive disease has excellent survival.
Lifelong follow-up with cystoscopy is essential due to recurrence risk.
