Abstract

Global cancer incidence and mortality rates are high and elevating. Worldwide, it is estimated that the annual number of cancer diagnoses will promote to 22 million by 2032.1 In spite of progress made in cancer chemotherapy, advanced solid tumors consisting of advanced carcinomas, sarcomas, melanoma, and glioblastoms, yet show wide problems in their treatment and traditional therapeutic agents alone have not produced satisfactory long-term clinical outcomes.2,3 Also, in those cases which the tumor has seemingly been eliminated fully, micro-metastases of inactive tumor cells often result to relapse and to therapeutic failing. Hence, considering the problems of scape and survival to cancer progress, most oncologists have concluded that no unique therapy is enough to treatment of cancer.4,5
