Dysgerminoma of the ovary: radiation therapy for recurrence and metastases.

Nine cases of dysgerminoma are reported. Five patients developed recurrence of disease in either the pelvis or metastatic sites including the lung and brain. The metastatic disease was controlled by a radiation dose of 2,000 to 3,000 rads during three to four weeks in four of the patients. The excellent response of dysgerminoma to radiation warrants an optimistic prognosis and vigilant follow-up since metastatic disease can be controlled by moderate radiation doses.
