Newer Targets of Therapy Photodynamic Therapy: Palliation Curative intent- Small primary tumor Second primary/ Recurrent tumor Premalignant lesions Antibody based Therapy Monoclonal Ab against EGFr-C225 Inhibitors of EGFr-ZD1839, Erlotinib HCl Gene Therapy
Slide 17-

Gene Therapy- Approaches Augmentation therapy Immunotherapy: Cytokine gene transfer- IL-2,IL-12, IFN- g Vaccination Tumor specific antigen Co-stimulator molecule Foreign antigen Chemotherapy: HSV TK Drug sensitization / Drug resistance Gene replacement Replace tumor suppressor gene- p53 Inhibit an oncogene- Antisense c DNA Adjuvant Therapy- Post CT / RT/ Surgery
