RE:RE:0.25 is resistence----- Would normally agree with you there tomchoco - 30 days`too early to posit the elimination of the cancer - EXCEPT for the example of P6 who was treated on the 7th of Feb 2018. They were able to use the Phrase ‘To date, the patient has shown no clinical evidence or presence of disease' as early as an update on the 16th of April of that year.
That Phrase has only ever been used for Ps 5 and 6 and for me is a cipher of their confidence that the cancer is completely destroyed. Guessing that the 30 day - and perhaps even earlier - can tell them all that they need to know.
