title: Diagnostic utility of Müllerian inhibiting substance determination in patients with primary and recurrent granulosa cell tumors.
abstract: OBJECTIVE
  In this study we evaluated changes in serum Müllerian inhibiting substance (MIS) concentration in a large number of patients with granulosa cell tumors (GCT) to determine whether MIS is elevated at the time of presentation and whether MIS is an index of successful surgical resection and management of recurrences.
  
  
  METHODS
  We retrospectively reviewed MIS levels from 17 subjects prior to tumor resection and studied serial MIS samples from 56 subjects following initial tumor resection. Clinical follow-up information was available for 36 of those with postoperative MIS values. Serum MIS was measured by an ELISA. MIS values were compared to a combination of normative values previously established in our laboratory and from more recently obtained samples from older pre- and postmenopausal women, using this assay.
  
  
  RESULTS
  Serum MIS was elevated pre-operatively in 6 of 8 (75%) subjects with juvenile GCTs and in 7 of 9 (78%) of those with adult GCTs relative to age-matched controls (76% for both types combined). Post-operative clinical correlation was available for 36 patients. There was no clinical recurrence in 21 subjects with normal or undetectable postoperative values, and incompletely resectable tumor or recurrence was identified in 6 of 15 patients with elevated postoperative values.
  
  
  CONCLUSIONS
  The results of this study demonstrate that postoperative serum MIS concentrations may be used to evaluate the completeness of tumor removal following initial surgery and that serial MIS determinations may allow the detection of recurrences.
