3. Conclusion

Cancer is a major problem worldwide and is the most common cause of death in many countries. Although treatment with conventional chemotherapy is widely successful, it fails to induce potent antitumor immune response. Emerging evidence indicates that treatment with metal-containing agents destroy cancer cells through ROS generation and also shows the way to cure cancer through inhibition or subvertion of immunosuppressive network toward proimmunogenic type. Strategies to target these molecular pathways by novel, cost-effective, redox-active molecules may usher a new era in immune therapy.
