Tried to find some stats on Google but failed. 50% was a figure I had in mind from days when I had bowel cancer (Dukes C)always thought that was about right but if it is nearer 20% then so be it. My point still remains - for those who decide that the detriments of chemo outweigh its benefits then Trovax may be of benefit - some may even respond well enough to be cured.
The trials to date compare Trovax with standard treatments but there seems little to show benefits by itself.
