Bladder cancer

Also known as urothelial carcinoma, transitional cell carcinoma, and depending on depth of invasion, non-muscle invasive bladder cancer and muscle invasive bladder cancer

Bladder cancer: an overview

Bladder cancer is uncommon

  • While relatively uncommon, bladder cancer can be lethal

  • Approximately 1,000 Australians die from this disease each year

There are many ways to treat bladder cancer

  • Flexible cystoscopy: a flexible camera to look inside the bladder, can be performed under general or local anaesthesia

  • Rigid cystoscopy + biopsy: a stiff camera to examine the inside of a bladder, and take small specimens to assessment under the microscope. This is only done under general anaesthesia.

  • Trans urethral resection of bladder tumour (TURBT) +/- instilling chemotherapy into the bladder

Three stages of bladder cancer

Bladder cancer have different stages of aggressiveness and spread. Each will have varying treatment options.

NMIBC


Non-muscle invasive bladder cancer

  • The tumour is limited to the inner two layers of the bladder (urothelium and lamina propria).

  • Within NMIBC, a patient may be further classified as low, intermediate, high or very high risk (of tumour progressing deeper into the bladder wall layers)

  • This classification is based the number of bladder tumours present and their size, grade (degree of cell abnormality), stage (depth of invasion), presence of carcinoma in-situ (a high risk non-invasive flat tumour), as well as the patient’s age and gender.

  • Treatment commences with tumour resection (TURBT)

  • Treatment can subsequently include observation (with regular camera checks into the bladder), liquid intravesical (into the bladder) treatments such as immunotherapy (Bacillus Calmette-Guérin; BCG) or chemotherapy (mitomycin, epirubicin, gemcitabine) or radical cystectomy (removal of the entire bladder).

MIBC


Muscle invasive bladder cancer

  • The tumour invades the muscle layer (muscularis propria)

  • This is life-threatening

  • The chief treatment options are radical cystectomy (removal of the entire bladder) often paired with chemo-therapy beforehand, or repeat TURBT paired with chemotherapy and radiotherapy.

mUC (U stands for urothelial)


Metastatic bladder cancer

  • The tumour has spread to other organs.

  • Your urologist will manage your condition in association with medical oncologists and other specialists.

  • Treatments can include radiotherapy and intravenous (into the veins) chemotherapy and/ or immunotherapy.

  • The focus moves from disease cure to disease control and symptom management.
