Kris,
When my mom had chemoembolisms done they were not done in conjunction with systemic chemotherapy. I do not know if a human could physically endure both at the same time. For her they worked really well and actually ended up shrinking her tumor enough to resect – but then it spread right before the surgery and the surgery was cancelled. They were really really hard on her but then she would get better after a few weeks and go right back to work (I think she had it done three times – each time the tumor died more and more). Hope this helps!
