Is clear cell cancer?

Clear cell renal cell carcinoma is a cancer of the kidney. The name “clear cell” refers to the appearance of the cancer cells when viewed with a microscope. [5258] Clear cell renal cell carcinoma occurs when cells in the kidney quickly increase in number, creating a lump (mass).

What type of cancer is clear cell?

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 clear cell carcinoma curable?

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.

Is clear cell carcinoma benign or malignant?

Clear cell renal cell carcinoma (CCRCC) is a renal cortical tumor typically characterized by malignant epithelial cells with clear cytoplasm and a compact-alveolar (nested) or acinar growth pattern interspersed with intricate, arborizing vasculature.

Can you survive clear cell sarcoma?

Studies estimate the 5-year survival rate of CCS is between 30% and 67%. Prognosis for CCS is poor because it often spreads quickly to other parts of the body and often comes back after treatment.

Is clear cell cancer hereditary?

Four hereditary renal cell cancer syndromes and the genes that cause them have been identified. VHL is a hereditary syndrome that increases the risk of renal cell cancer and renal cysts. VHL is associated with a clear-cell type renal cell cancer, which is typically slow growing.

Why is clear cell carcinoma clear?

CCCs make up 5%–25% of all ovarian cancers, making them the most common type after the HGSCs [46]. They are so named because the cancer cells typically have abundant clear cytoplasm due to the presence of intracytoplasmic glycogen, which is lost during processing (Fig. 4).

How fast does clear cell carcinoma grow?

Clear cell carcinoma (0.86 cm/year) tended to grow faster than papillary cell carcinoma (0.28 cm/year) (P = 0.066).

What causes clear cell carcinoma?

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.

What does it mean clear cell carcinoma?

Listen to pronunciation. (kleer sel KAR-sih-NOH-muh) A rare type of tumor, usually of the female genital tract, in which the insides of the cells look clear when viewed under a microscope. Also called clear cell adenocarcinoma and mesonephroma.

Can clear cell renal cell carcinoma metastasis?

Clear cell renal carcinoma is known for its propensity for metastatic spread. Common sites of metastasis are the lungs, bones, lymph nodes, liver, adrenals and brain, but all organs can be affected. Contralateral ureteral metastasis is a rare phenomenon, and only a few cases have been reported in the literature.

What is a clear cell?

In histology, a clear cell is a cell that shows a clear cytoplasm when stained with hematoxylin and eosin (H&E).

Is clear cell sarcoma fatal?

The prognosis of clear cell sarcoma is guarded, mainly because the disease is difficult to catch early and is prone to relapse and spread long after initial diagnosis. The five, ten and twenty year disease-specific survival rates have been reported as 67%, 33%, and 10%, respectively.

How many cases of clear cell sarcoma are there?

Clear cell sarcoma is a rare soft tissue neoplasm. However, early diagnosis is crucial to prevent metastasis and worsened prognosis. Clear cell sarcoma has an extremely poor prognosis once metastasis occurs, and to the best of our knowledge, only fewer than 100 cases have been reported in the literature.

How can you tell the difference between melanoma and clear cell sarcoma?

Compared to melanoma, clear cell sarcoma occurs in much younger patients, is deeply located, associated with tendons or aponeuroses, lacks epidermal involvement, tends to display less cellular pleomorphism, and may contain Touton-type neoplastic giant cells; these features are unusual for melanoma.
