Dysgerminomas

Treatment options for stage I dysgerminomas include:

For patients with stage I dysgerminoma, unilateral salpingo-oophorectomy conserving the uterus and opposite ovary is accepted treatment of the younger patient who wants to preserve fertility or a pregnancy. Postoperative lymphangiography or CT 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% of these patients will relapse, but they can be treated successfully at the time of recurrence with a high likelihood of cure.

Incompletely staged patients or those with higher stage tumors should probably receive adjuvant treatment. Options include radiation therapy or chemotherapy. A disadvantage of the former is loss of fertility resulting from ovarian failure. Experience with adjuvant chemotherapy is limited, but considering the effectiveness of chemotherapy in tumors other than dysgerminoma and in advanced stage dysgerminoma, adjuvant chemotherapy is likely to be very effective and to allow recovery of reproductive potential in patients with an intact ovary, fallopian tube, and uterus.[1]
