reader judge the strength of evidence linked to the reported results of a
therapeutic strategy. (Refer to the PDQ summary on Levels of Evidence for more

Dysgerminomas
Standard treatment options:
- For patients with stage I dysgerminoma, unilateral salpingo-oophorectomy
conserving the uterus and opposite ovary is accepted treatment of the younger
patient anxious to preserve fertility or to preserve a pregnancy.
Postoperative lymphangiography or computed tomography is indicated before
treatment decisions are made for patients who have not had careful surgical and
pathological examination of pelvic and para-aortic lymph nodes during surgery.
Patients who have been completely staged and have stage IA tumors may be
observed carefully after surgery without adjuvant treatment. About 15% to 25%
will recur, but can be treated successfully at the time of recurrence with a
high likelihood of cure. Incompletely staged patients or those with higher
stage tumors probably should receive adjuvant treatment. Options include
radiation therapy or chemotherapy. A disadvantage of the former is loss of
fertility due to ovarian failure. Experience with adjuvant chemotherapy is
limited, but considering the effectiveness of chemotherapy in tumors other than
dysgerminoma and in advanced stage dysgerminoma, it is likely to be very
effective and to allow recovery of reproductive potential in patients with an
intact ovary, tube, and uterus.[1]
Other Germ Cell Tumors
Standard treatment options:
Current Clinical Trials
Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with stage I 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.
