Is radiotherapy effective after ovarian cancer metastasis?

Attention should be paid to the effect of radiotherapy after ovarian cancer metastasis. The answer to this question is as follows: Radioimmunotherapy: The radiosensitivity of ovarian malignant tumor varies greatly, endodermal sinus tumor, immature teratoma and embryonic cancer are the least sensitive, epithelial ovarian cancer and granular cell cancer are moderately sensitive, and asexual cell tumor is the most sensitive, which can be controlled by radiotherapy after operation. Because of the early abdominal metastasis of ovarian cancer, the irradiation range includes abdominal cavity and pelvic cavity. The liver and kidney areas should be protected to avoid radiation damage.
