What is a transitional cell tumors?

Is transitional cell carcinoma serious?

If it’s high grade, it’s more likely to spread to deeper layers of your bladder, other areas of your body, and your lymph nodes. It’s also likely to come back after treatment. High-grade TCC is the type of bladder cancer that is more likely to be life-threatening.

What is transitional cell?

(tran-ZIH-shuh-nul sel) A cell that varies in shape depending on whether the tissue is being stretched. Transitional cells may be stretched without breaking apart. They line hollow organs such as the bladder.

How aggressive is transitional cell carcinoma?

Primary transitional cell carcinoma of the ureter is an aggressive disease with a high progression rate, as over half of cases are invasive and approximately one-quarter of them have a regional metastasis at diagnosis compared to 15% and 20% for all bladder tumors [3–5].

Can you survive transitional cell carcinoma?

Transitional cell carcinoma of the renal pelvis, accounting for only 7% of all kidney tumors, and transitional cell cancer of the ureter, accounting for only 1 of every 25 upper urinary tract tumors, are curable in more than 90% of patients if they are superficial and confined to the renal pelvis or ureter.

Is transitional cell carcinoma fatal?

Renal UC is uniformly fatal unless it is treated. In a multicenter study of 1363 patients with upper urinary tract urothelial carcinoma who were treated with radical nephroureterectomy, the 5-year cancer-specific survival probability was approximately 73%.

How does transitional cell carcinoma spread?

While transitional cell carcinoma originates along the ureter, high-grade cases allow it to spread (metastasize) into other organs and areas of the body. The prostate is the most commonly affected organ, as it is connected to the urinary system via ducts.

How does transitional cell carcinoma affect the body?

Cancer that begins in the transitional cells is the most common type of cancer that develops in the renal pelvis and ureter. In some cases, transitional cell cancer metastasizes, which means that cancer from one organ or part of the body spreads to another organ or part of the body.

Can a cancerous ureter be replaced?

Surgery is often recommended to remove ureteral cancer. The extent of your surgery will depend on your situation. For very early-stage ureteral cancer, surgery may involve removing only a portion of the ureter.

Where does transitional cell carcinoma metastasis?

Transitional cell carcinoma (TCC) of the bladder commonly metastasizes to the pelvic lymph nodes, lungs, liver, bones, adrenals, or brain. Unusual sites include the heart, kidney, spleen, pancreas, and reproductive system.

What causes TCC?

The exact cause of upper urinary tract TCC is not known; however, several risk factors have been identified. Workers in the chemical, petrochemical, aniline dye, and plastics industries, as well as those exposed to coal, coke, tar, and asphalt, are at increased risk for renal pelvis and ureteral tumors.

What is TCC dog?

TCC is also called urothelial carcinoma. TCC is a malignant tumor that develops from the transitional epithelial cells that line the bladder. In dogs, this tumor invades into the deeper layers of the bladder wall including the muscle layers.

What is upper tract transitional cell carcinoma?

Upper urinary tract transitional cell carcinoma (TCC) refers to malignant changes of the transitional epithelial cells lining the urinary tract from the renal calyces to the ureteral orifice.

How aggressive is transitional cell carcinoma in dogs?

It is aggressively malignant and generally grows in an area not very amenable to surgical removal. If the tumor becomes so large and deeply invasive that the patient cannot urinate, an unpleasant death ensues in a matter of days.

What happens if your ureter is removed?

If a large section is removed, tissue is used to repair the ureter. This tissue is taken from another part of the body, such as the bladder. The cut ends of the ureter are then stitched together.
