CA-125

A useful tumor marker for ovarian carcinomas because it reacts with most epithelial ovarian neoplasms of serous, endometrioid, clear cell, and undifferentiated types. It has also been described in other neoplasms such as seminal vesicle and anaplastic lymphomas. It also reacts with both normal tissues and neoplasms of fallopian tube, endometrium, endocervix, and mesothelioma, but does not react with mucinous ovarian tumors and colon cancer, and normal tissues such as breast, liver, skin, kidney, and spleen are negative.
