Is clear cell renal carcinoma aggressive?
These tumors are rare, accounting for only 3 to 5 percent of RCC tumors, but they can be quite aggressive and require prompt treatment.
What type of cancer is clear cell carcinoma?
Clear cell renal cell carcinoma, or ccRCC, is a type of kidney cancer. The kidneys are located on either side of the spine towards the lower back. The kidneys work by cleaning out waste products in the blood. Clear cell renal cell carcinoma is also called conventional renal cell carcinoma.
Is renal oncocytoma cancerous?
Most renal oncocytomas are benign (non-cancerous) and metastasis is very rare.
Should a benign kidney tumor be removed?
Because benign kidney tumors do not require removal, a kidney specialist known as a urologist may order additional tests to help determine if a tumor is benign before treatment decisions are made. These tests may include imaging tests or a biopsy, in which a sample of the tumor is taken with a needle.
How serious is clear cell carcinoma?
Patients with clear cell renal cell carcinoma (CCRCC) tend to have a worse prognosis than patients with other histologic subtypes of RCC, with 5-year disease-specific survival rates of 50-69%, compared with 67-87% for papillary RCC and 78-87% for chRCC.
How aggressive is clear cell carcinoma?
Clear cell carcinoma comprises a rare yet an aggressive subtype, accounting for less than 5% of all uterine carcinomas.
Which renal cell carcinoma has best prognosis?
CHROMOPHOBE RENAL CELL CARCINOMA
Chromophobe RCC represents about 5% of all malignant renal epithelial tumors, and is most frequent in the sixth decade of life. Such a subtype is less aggressive than ccRCC(3,11), and carries the best prognosis amongst RCCs. Metastasis occurs in only 7% os cases.
How fast does clear cell cancer grow?
Clear cell carcinoma (0.86 cm/year) tended to grow faster than papillary cell carcinoma (0.28 cm/year) (P = 0.066). The mean growth rate of grade 2 tumors (0.88 cm/year) was faster than that of grade 1 tumors (0.36 cm/year) (P = 0.041).
What causes clear cell cancer?
Though the exact cause of clear cell renal cell carcinoma is unknown, smoking, the excessive use of certain medications, and several genetic predisposition conditions (such as von Hippel Lindau syndrome) may contribute to the development of this type of cancer.
