CONVENTIONAL CANCER THERAPIES

Halsted’s Radical Mastectomy vs ‘Lumpectomy’

3-D structure & schematic of p-glycoprotein

Examples: Methotrexate Eg. Doxorubicin Eg. Cyclophosphoramide, Melphalan

Eg. Vinblastine, paclitaxel

Newer Approaches to Cancer Therapy

Incorporate Predictive Diagnosis

Are Mechanism Based

Designed for Selectivity
