When endometrial cancer metastasizes to lungs, common treatments include surgery, chemotherapy, radiotherapy, hormone therapy, targeted therapy, etc., which should be carried out according to doctor’s instructions. 1. Surgery: for patients with endometrial cancer metastasized to lungs, after evaluating whether surgical treatment is possible, tumor cytoreductive surgery (including removal of enlarged lymph nodes) can be considered. 2. Chemotherapy: chemotherapy is systemic treatment, which is applicable to the stage of endometrial cancer metastasized to lungs and can reduce distant metastasis outside the pelvis. Commonly used chemotherapeutic drugs include cisplatin, doxorubicin, paclitaxel and so on. They can be applied alone or in combination, or combined with progesterone. 3. Radiotherapy: it is one of the effective methods for treating endometrial cancer, which is divided into two kinds: brachytherapy and extracorporeal irradiation. 4. Hormone therapy: it can be one of the comprehensive treatments for endometrial cancer metastasized to lung. Hormonal therapy drugs include progestins, such as medroxyprogesterone acetate, medroxyprogesterone acetate; anti-estrogenic drugs, such as selective ER modulators, selective ER down-regulators and aromatase inhibitors; and gonadotropin-releasing hormone agonists, such as leuprolide and treprostinil. 5. Targeted therapy: Targeted therapy drugs can effectively prevent the growth of cancer cells, such as epidermal growth factor receptor antagonists, mammalian target protein inhibitors of rapamycin. Patients should actively cooperate with doctors’ treatment, establish confidence in treatment, and do not use drugs on their own, so as to avoid delaying the condition and affecting the prognosis of the disease.
