Ovarian cancer spreading to the abdominal cavity indicates that the patient’s condition is more serious and usually has reached the advanced stage, at this time, the patient needs to seek medical treatment in time and adopt surgical treatment and medication to treat the disease. Ovarian cancer spreading to the abdominal cavity requires standardized evaluation. If the metastasis is purely in peritoneum and lymph nodes, such patients need to remove the lesions as much as possible through surgery to control the development of the disease. Other non-surgical treatments need to be combined after surgery. If the abdominal metastasis is large and involves vital organs, the timing of surgery is missed. Chemotherapy, radiotherapy, targeted therapy, etc. are feasible. Patients need to choose the appropriate chemotherapy and radiotherapy regimen according to their actual tumor type. Commonly used chemotherapy drugs include paclitaxel and carboplatin. At the same time, patients can also be treated with targeted therapy with adenosine diphosphate ribosomal polymerase inhibitors such as olaparib and anti-angiogenic drugs such as bevacizumab. Patients are advised to seek medical treatment as soon as possible to avoid delay.
