Cancer Metastasis Treatments

More than 90% of cancer deaths are caused by cancer metastasis. Since cancer metastasis is the main cause of human deaths, so in this article more attention will be paid to it than ever before. Presently, clinical cancer chemotherapies have been targeting on primary tumors rather than on metastatic processes. Since the antimetastatic drugs are different from antiproliferative drugs and underinvestigated, cancer patients’ survival has been improved on a small scale now. To change this stalemate, this problem is reiterated by an analysis of the relationship between pathology, pharmacology and clinical therapy of neoplasm metastasis and it is suggested to improve the outcome of chemotherapy of cancer patients from different possible ways; e.g. to make more efforts to manufacture new types of antimetastatic drugs and optimize use of these drugs in clinics.
