The limitations implied by the word 'could' are ignored by both the journalist and the researcher of this treatment. The researcher even suggests thousands of lives could be saved by the treatment. But no evidence is provided for this, nor even any evidence to support the claim that the treatment 'shrinks tumours and stops them metastising' in humans, apparently by 'revving up the immune system'. The 'extremely good results', however, were obtained in animals, not humans. Studies in people with bladder cancer are just beginning. The Cancer Council comment is appropriately cautious.
The journalist and the researcher could read the recent FDA expert panel advice that bevacizumab (Avastin) approval for use in breast cancer be removed - it was approved on evidence it shrank tumours and slowed progression - in practice it did not live up to these promises, and most importantly, did not extend life. It also had significant toxicity.
