Antecedent factors and outcome in amenorrhea-galactorrhea.
One hundred seventeen patients with amenorrhea and galactorrhea or hyperprolactinemia were evaluated with regard to antecedent factors, results of investigations, and management. Full details of the outcome of prolonged follow-up were available for 104 patients. Patients who developed amenorrhea-galactorrhea after withdrawal of oral contraceptives or postpartum had a lower incidence of pituitary adenomas than did those who developed amenorrhea-galactorrhea spontaneously. Six of a total of 40 tumors were detected only during the follow-up period. This study suggests that patients with spontaneous amenorrhea-galactorrhea have a greater risk of developing a detectable pituitary adenoma than do those with postpill or postpartum symptoms. However, patients with a microadenoma are more likely to have had postpill onset of hyperprolactinemia. Plasma prolactin (PRL) in patients with postpill amenorrhea-galactorrhea increased in proportion to the duration of oral contraceptive use.
