Cytoplasmic CD24 expression in advanced ovarian serous borderline tumors

The loss of apical localization with the acquisition of the cytoplasmic staining of CD24 protein is a surrogate marker of stromal invasion in ovarian serous tumors of borderline malignancy. Furthermore, the increase in the cytoplasmic expression of CD24 protein is a strong independent molecular marker for shortened survival rate of patients with ovarian serous adenocarcinomas.
