Ovarian cancer does not have any specific cure-all treatment. Most ovarian cancers are epithelial ovarian cancers, and there is also ovarian cancer resulting from malignant germ cells, which is a rarer pathology type. For epithelial ovarian cancer, treatment methods include surgery, radiation therapy, chemotherapy, and some targeted therapies, mainly using Bevacizumab, which is a monoclonal antibody that inhibits angiogenesis, and is usually used in combination with chemotherapy drugs. For patients with advanced ovarian cancer, those who are resistant to chemotherapy, or those in poor general health unable to endure chemotherapy, palliative treatments like hormone treatment using progestogens are an option, along with immune therapy being available nowadays. Surgery is primarily for early-stage ovarian cancer patients, where curative surgical resection is possible, or for debulking surgery in patients with advanced ovarian cancer. Chemotherapy is frequently used as it is relatively effective for epithelial ovarian cancer, a type of cancer that is somewhat sensitive to such treatments. The drugs used mainly include taxane combined with platinum-based chemotherapy. For intravenous administration or intraperitoneal delivery—for the latter, mainly for ovarian cancers complicated by extensive ascites—, positioning an abdominal drainage tube and then infusing platinum-based chemotherapy drugs into the abdominal cavity are utilized.
