You can't just make things up!!! Any approval of DCVax (highly doubtful) would be WITH SOC. It's not up to the patient to decide what they want. DCVax was never tested as a stand alone treatment. I don't know where or from whom you get these wild ideas, but you should certainly change your sources.
"The placebo patients in the phase 3 trial for DCVax-L (NCT00045968) received standard of care (SOC) therapy, which consisted of surgery, radiotherapy, and temozolomide chemotherapy following the Stupp protocol for newly diagnosed glioblastoma.
This design ensured both arms got equivalent SOC, allowing assessment of the vaccine's added benefit"
Good luck.
