Clear-cell Carcinoma Cells (COCC)

Clear cell ovarian tumors are part of the surface epithelial-stromal tumor group of ovarian cancers, accounting for 6% of these cancers. Clear cell tumors are also associated with the pancreas and salivary glands. Typically, they are cystic neoplasms with polypoid masses that protrude into the cyst. Benign and borderline variants of this neoplasm are rare, and most cases are malignant. These tumors may have a worse prognosis than serous tumors. ES-2 human clear cell ovarian carcinoma cells has been widely used in scientific research.
