Understanding the Most Common Types of Kidney Cancer


Four Major Types of Kidney Cancer

Transitional Cell Carcinoma (TCC)

This type of cancer develops in the center of the kidney, known as the renal pelvis. It affects the transitional cells in the lining of the renal pelvis — cells that stretch and change shape in organs and tissues that need to expand.

TCC accounts for less than 10 percent of kidney cancers, but like RCC, risk factors include smoking; exposure to industrial dyes, rubber, plastics, aluminum, and pesticides; and using certain types of pain killers for a long time.

Transitional cell cancer can affect the bladder, ureter, and urethra, too. Depending on what is affected and how far the cancer has spread, you could experience pain around the top of your hip bone and pain during urination, in addition to the typical kidney cancer symptoms.

Renal Sarcoma

Rarer than other types of kidney cancer, renal sarcoma begins in the connective tissue of the kidney. But while it accounts for so few cases, renal sarcoma carries a particularly bad prognosis.

One recent study found the majority of patients (both those whose cancer had spread and those who only had cancer in the kidney) lived less than five years.

Despite the grim outlook, renal sarcoma isn’t necessarily incurable. If the stage of the cancer is early, and the grade is low, surgery can increase chances of survival by quite a bit.

Treating Different Types of Kidney Cancer

Kidney cancer treatment will depend a lot on stage, grade, and type. In most cases, catching the cancer early will mean a very positive prognosis (many people will go into remission and regain health without any permanent damage to the kidney). Unfortunately, many cases are caught later, when more targeted and invasive treatment is needed.

The most common kidney cancer treatments include:

  • Surgery. This is often the main line of attack for kidney cancer since many tumors are contained and can be extracted without affecting kidney function. In some cases, the whole kidney will be removed, but most people can live perfectly normal and healthy lives with just one functioning kidney.
  • Ablation. When removing the tumor is too dangerous, or the whole tumour can’t be removed, an ablation might be more effective. A radiofrequency ablation (RFA) involves inserting a thin needle into the tumor to destroy it with an electrical current.
  • Immunotherapy. Also known as biologic therapy, immunotherapy aims to boost the body’s natural defenses to fight the cancer from within. This is an exciting new form of treatment that has helped many patients, and can be combined with other treatments.
  • Targeted therapy. This targets the cancer’s genes, proteins, or other characteristics that encourage cancer growth, without harming the healthy cells. Some targeted therapies are designed to starve the tumor by stopping blood vessels from developing, while others prevent certain proteins from feeding the cancer cells.

Chemotherapy and radiation are generally not used as primary treatments for kidney cancer, because of the damage they cause to healthy surrounding tissues. However, they can be used alongside other treatments, especially if the cancer has spread outside the kidneys.
