The clinical value of tumour markers in the management of ovarian cancer.

Inpersons had colorectal cancer and died from this cancer in this country.
Por ello, el principal dato a tener carcinoembriogenicoo cuenta va a ser el cambio cuantitativo de los MT. The serum dosage of CEA at diagnosis has low sensitivity because patients with colorectal cancer can have normal levels of serum CEA.
