Neoadjuvant therapy is the administration of therapeutic agents before a main treatment. One example is neoadjuvant
hormone therapy prior to radical
radiotherapy for
adenocarcinoma of the
prostate. Neoadjuvant therapy aims to reduce the size or extent of the cancer before using radical treatment intervention, thus making procedures easier and more likely to succeed, and reducing the consequences of a more extensive treatment technique that would be required if the tumor wasn't reduced in size or extent.
