Bladder Cancer Flashcards
Bladder cancer
Cancer in bladder arising from endothelial lining (urothelium).
Majority are superficial (not invading muscle) at presentation.
Risk factors for bladder cancer
- smoking
- increasing age
- aromatic amines (in dye, rubbber)
- schistosomiasis (-> squamous cell)
Stereotypical presentations relating to patients occupation (x3)
Dye factory worker:
- transitional cell carcinoma of bladder
Asbestos exposure:
- mesothelioma
Outdoor workers:
- skin cancers
Types of bladder cancer
- transitional cell carcinoma (90%)
- squamous cell carcinoma (5% - schistosomiasis)
- adenocarcinoma (2%)
Clinical features of bladder cancer
- painless haematuria
- other LUTS
- suprapubic pain
Referral criteria for suspected bladder cancer
2 week urgent pathway:
- > 45yrs with unexplained visible haematuria (without UTI or persisting post-UTI treatment)
- > 60yrs with microscopic haematuria PLUS dysuria or raised WCC
Non-urgent:
- > 65yrs with recurrent, unexplained UTIs
Diagnosing bladder cancer
Cystoscopy
- bladder through urethra into bladder
Staging bladder cancer
Distinctions:
- non-muscular-invasive
- muscular-invasive
TNM:
- non-muscular-invasive (in situ, Ta, T1)
- muscular-invasive (T2-T4, any N, any M)
Treatment options for bladder cancer
- transurethral resection of bladder tumour (TURBT)(NMIBC)
- intravesical chemotherapy (via catheter into bladder)
- intravesical cacillus calmette-geurin (BCG) (BCG vaccine into bladder, immune system attacks tumour)
- radical cystectomy (-> urostomy etc.)
- chemotherapy and radiotherapy
Urostomy
- drains urine from kidney, bypassing ureters, bladder and urethra
- most common solution post-cystectomy
