Urothelial Carcinoma or Bladder Cancer

If you or someone you know has been diagnosed with urothelial carcinoma or bladder cancer, you may be trying to learn as much as possible about the disease and its treatments. Read on to find out more.

The information on this website should be discussed with your healthcare professional and does not replace their advice.

What is urothelial carcinoma?

Urothelial carcinoma is the most common type of bladder cancer. It starts in the urothelial cells that line the bladder wall. The bladder is a hollow sac that stores urine (pee).

Another name for urothelial carcinoma is transitional cell carcinoma.

Urothelial carcinoma is more common in men than in women.

Treatment with KEYTRUDA® (pembrolizumab)

Your doctor will plan your treatment according to your individual circumstances. These include the type of cancer, how far your cancer has spread through the layers of your bladder and your general health.

KEYTRUDA is an immunotherapy that may be used to treat urothelial carcinoma when it has spread beyond the bladder and:

You are not able to receive a particular platinum-containing chemotherapy and your tumour tests positive for PD-L1; or
You are not able to receive any platinum-containing chemotherapy; or
You have received platinum-containing chemotherapy.

KEYTRUDA may also be used to treat bladder cancer if:

Your cancer has not spread to nearby tissues in the bladder, but is at high-risk of spreading; and
You have tried treatment with an immunostimulant and it did not work; and
You are not able to or have decided not to have surgery to remove your bladder.

Talk to your doctor to see if KEYTRUDA may be right for you.

KEYTRUDA is not funded in New Zealand for the treatment of patients with urothelial carcinoma or bladder cancer.

KEYTRUDA may be used in adults to treat certain cancers when the cancer has spread (metastatic) or cannot be removed by surgery (unresectable), such as:

melanoma
non-small cell lung cancer
urothelial carcinoma
head and neck squamous cell carcinoma
renal cell carcinoma
oesophageal carcinoma
cervical cancer
endometrial carcinoma
gastric or gastroesophageal junction adenocarcinoma
triple-negative breast cancer
cutaneous squamous cell carcinoma
a kind of cancer that can occur in any part of the body and is shown by a laboratory test to be microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR)
colon or rectal cancer that is shown by a laboratory test to be MSI-H or dMMR

KEYTRUDA may also be used in adults:

after surgery to remove melanoma, non-small cell lung cancer, or renal cell carcinoma to help prevent the cancer from coming back
before surgery to treat triple-negative breast cancer and then continued after surgery to help prevent the cancer from coming back
to treat bladder cancer which has not spread to nearby tissues but is at high-risk of spreading and where bladder removal is not preferred
to treat classical Hodgkin Lymphoma (cHL) that has returned or when other treatments have not worked

KEYTRUDA may be used in children with cHL, MSI-H or dMMR cancer, or after surgery to remove melanoma. It is not known if KEYTRUDA is safe and effective in children with MSI-H or dMMR cancer of the brain or spinal cord (central nervous system cancers).

KEYTRUDA may sometimes be given in combination with other anti-cancer medicines.
