The prognosis for stage 3 renal cell, or kidney, cancer is a 53 percent survival rate five years after diagnosis, according to the American Cancer Society. Many factors affect the survival rate, including other health conditions the patient has and how well the cancer responds to treatment.
Kidney cancer patients tend to be older, which also affects the survival rate, Healthline reports. The largest determinant in calculating the survival rate is the stage of the cancer at diagnosis.
When this cancer spreads it is through lymph nodes, blood or tissue near the original cancer site, says Healthline. Stage 3 kidney cancer has spread from its original location into a primary kidney blood vessel, fatty tissue around the kidney or a lymph node near the kidney.
Treatment options for renal cell cancer patients include surgery, which often includes removing all or part of the kidney, Healthline states. Doctors also use cryoblation, a procedure that freezes the cancer cells. As of 2015 several medications that target kidney cancer cells also show some promise in keeping the disease from spreading.
Renal cell cancer develops in the kidney's tubules, which are tube-like structures that filter waste by-products from blood to produce urine, Healthline explains. The most common symptom of kidney cancer is blood in the urine, but patients also sometimes feel a lump in the stomach.
