Honestly, you are not making sense here. The crossover arm were patients who, like the treatment arm, got the current standard of care first, but their disease recurred. Then they received DCVax-L, if they agreed to crossover, but they did not know if they had it first or a placebo first or vice versa. They basically agreed to continue. The reality is, they are in fact the standard recurrent patient without surgery at that point.
The more likely scenario to get even better results will be the recurrent patient who has a tumor removed after recurrence and a new vaccine made. These patients had their original vaccine, and still far exceeded normal survival for recurrence.
