To evaluate natural history of ovarian dysgerminoma and role of radiation therapy in treatment of ovarian dysgerminoma, retrospective study was carried out in 5 nonirradiated cases and 20 irradiated cases. Conclusions are as follows: 1. Radiation therapy is essential in treatment of ovarian dysgerminoma. 2. Even in stage 1 a, significant recurrence rate is expected in surgery only group. 3. Even in recurrent cases, if adequate radiotherapy is given in stage 1-, we can predict near complete curability and in stage 4, we can get considerable benefit. 4. Dysgerminoma beyond stage 2 is highly fatal without radiotherapy. 5. Involved field irradiation including whole abdomen and booster RT on bulky tumor area is sufficient in radiotherapy of stage 1, 2, 3, without paraaortic node involvement. Further mediastinal and supraclavicular irradiation is indicated in stage 4 or stage 1, 2, 3, with paraaortic involvement. 6. If bilateral salphingoophorectomy was done. Elective irradiation is recommended in any condition because preservation of avarian function is not further needed. 7. Incases of small encapsulated stage 1a, We can delay post op. RT under close observation in order to preserve fertility.
