Radiation therapy is seldom indicated for epithelial ovarian cancer and fallopian tube cancer. In some cases, it may be appropriate to give palliative radiation treatment. This applies to tumors that have ruptured the vagina and cause bleeding. Radiation therapy is also given in cases of brain metastases.
Non-epithelial ovarian cancer is generally sensitive to radiation therapy, but is only used in rare cases. Radiation therapy may be considered for treating recurrence, since these tumors are radiosensitive.
