How do you decide on adjuvant therapy in a patient with a Stage IA uterine carcinosarcoma without any myometrial invasion?   

The NCCN recommends either systemic therapy + brachytherapy or pelvic RT + brachy or brachy alone or observation. How do you decide among these options? Does your recommendation change if there is invasion but < 50%?
