Drugs that inhibit the spread of cancer cells mainly include chemotherapeutic drugs, targeted drugs, immune drugs, endocrine drugs and so on. 1. Chemotherapeutic drugs, such as azulpiridine and vincristine, mainly act in different growth and reproduction phases of tumor cells, thus inhibiting the growth of tumor cells or killing tumor cells directly, and therefore can inhibit the spread of cancer cells. 2. Targeted drugs: such as Sorafenib, Gefitinib, etc., mainly act on specific targets to kill cancer cells. 3. Immune drugs: such as PD-1, PD-L1, etc., mainly act on the immunosuppressive checkpoints, which make the body’s autoimmune system find the cancer cells and attack them, thus inhibiting the spread of cancer cells. 4. Endocrine drugs: such as ER, PR-positive breast cancer patients can choose tamoxifen, aromatase inhibitor for endocrine therapy; for advanced prostate cancer or early prostate cancer with short life expectancy, endocrine therapy such as desmoplasia and anti-androgenism can be chosen. When cancer patients use drugs to inhibit cancer metastasis, the specific drug program should be used under the guidance of professional doctors, and should not use drugs without authorization.
