When reading the news, we often see such expressions, which makes us very confused:

Urothelial carcinoma (UC) is the most common malignant tumor in the urinary system.

Urothelial carcinoma (UC), also known as transitional cell carcinoma (TCC), is currently the most common type of bladder cancer, accounting for more than 90% of all bladder cancers

Bladder cancer is urothelial cancer?

Urothelial cancer is the most common type of bladder cancer?

What is their relationship?

Let me explain!

Classification of Urothelial Cancer

Urothelial carcinoma (UC) is one of the most common malignant tumors in the genitourinary system.

According to the anatomical location, UC is divided into upper urinary tract urothelial cancer (renal pelvis, ureter) and lower urinary tract urothelial cancer (bladder, urethra).

In addition, for example, "urinary pelvic urothelial carcinoma" is the standard term, because "urothelial carcinoma" is a proper term involving pathology

Because urethral cancer is rare, many references including CSCO guidelines classify UC into upper urothelial cancer and bladder cancer

Key issues

Bladder urothelial cancer = bladder cancer?

Among the pathological types of bladder cancer, urothelial (transitional cell) is the most common

Picture: Draw Medicine Rubik's Cube

Because bladder urothelial cancer accounts for ~90% of bladder cancer, bladder cancer is usually referred to as bladder urothelial cancer

One sentence summary: About 90% of urothelial cancers (UC) are bladder cancer (more accurately, it is bladder urothelial cancer, because about 90% of bladder cancer is derived from urothelium)
