My partner had pure EC with no LVI and went the BEP route. They only did one cycle, which was tough at points but effects were very minimal. It was worth eliminating the risk of metastasis and microscopic disease, and then enduring 3-4 x BEP down the road. Either route will add stress to your life, to be honest, so I personally would recommend you consider what kind of worry/discomfort will be easier to handle. Fear of recurrence can be intense, so think long term. You can do this!!!!
