Treatment of Malignant Gonadal GCTs

    continued...

    A multidisciplinary approach is essential for treatment of ovarian GCTs. Various surgical subspecialties and the pediatric oncologist must be involved in clinical decisions. The reproductive surgical approach for pediatric GCTs is often guided by the hope that function can be preserved. In a completed pediatric intergroup trial, pediatric patients with ovarian GCTs (stages I-IV) had excellent survival with PEB and conservative surgery, rather than the strict guidelines proposed originally in the study.[29] The role of laparoscopy in children with ovarian GCTs has not been well studied.

    Standard treatment options

    Surgery: The role for surgery at diagnosis is age- and site-dependent and must be individualized. Primary resection is appropriate when feasible without undue risk of damage to adjacent structures; otherwise, an appropriate strategy is biopsy for diagnosis followed by subsequent surgery in selected patients who have residual masses following chemotherapy.

    Stages I through IV

    • Surgery and treatment with four to six cycles of standard PEB, with the exception of patients with stage I ovarian GCTs for whom observation is currently being evaluated. These patients have an OS outcome greater than 90% with this regimen, suggesting that a reduction in therapy could be considered.[8,9,29]
    • Surgery and treatment with six cycles of JEB.[10,29]

    Treatment options under clinical evaluation for stages I through III

    The following is an example of a national and/or institutional clinical trial that is currently being conducted. Information about ongoing clinical trials is available from the NCI Web site.

    • A United Kingdom CCG trial is studying the reduction of total JEB cycles.

    Current Clinical Trials

    Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with childhood malignant ovarian germ cell tumor. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

    General information about clinical trials is also available from the NCI Web site.
