10 U/ml (OR 2.86, p 0.01) remained the only independent factors to predict ovarian cancer recurrence. Conclusions The present paper proposes the validation of a novel CA125 algorithm aiming to detect recurrent EOC. These data may allow us to investigate novel ways of follow up that do not require a patient's physical attendance at a clinic (virtual follow-up)."/>
