Experts analyze common methods of radiotherapy for ovarian cancer

Radiation is an effective treatment for ovarian cancer. It is very effective in treating ovarian cancer and is therefore a common treatment for many ovarian cancer patients. What are the common methods of radiation therapy for ovarian cancer ? Here are some common methods of radiation therapy for ovarian cancer.

In general, common radiation treatments for ovarian cancer include:

The radiosensitivity of ovarian cancer varies greatly. Endodermal sinus tumor, immature teratoma, embryonal carcinoma are the least sensitive, while epithelial ovarian cancer and granulosa cell carcinoma are the least sensitive. Moderately sensitive dysgerminoma is the most sensitive. Radiotherapy after surgery can usually control the early metastasis of ovarian cancer to the abdominal cavity. Therefore, the scope of irradiation treatment for ovarian cancer includes the abdominal cavity and pelvic cavity. The liver and kidney areas are protected to avoid radiation damage. When treating ovarian cancer, the radiation dose for the whole abdominal cavity is 3000cGY~5000cGY/6~8 weeks.

Internal irradiation refers to the injection of gold (198AU) or phosphorus (32P) into the abdominal cavity, which can make the abdominal surface reach a dose that is difficult to reach with external irradiation. It is a common method for treating ovarian cancer. Due to its limited penetration, it can be used to treat superficial metastases in the abdominal cavity. It can improve the five-year survival rate for patients with residual tumors under the microscope or ruptured stage I tumors during surgery. The disadvantage of this method of treating ovarian cancer is that the abdominal cavity must be free of adhesions to ensure uniform distribution of radioactive isotopes. Otherwise, it can cause intestinal damage and cause serious consequences. Generally, the amount of 198AU is 120-150 millicuries and the amount of 32P is 10-20 millicuries.

The above is an introduction to the common radiotherapy methods for ovarian cancer. I hope it will be helpful to everyone. Patients should choose the method of ovarian cancer treatment that suits them according to their actual condition and should not choose blindly.
