Good afternoon all. I have followed this board for a long time. I have a question for those more knowledgeable than myself? Dr. Musella is saying that 0% survived in the external control arms for 5 years. However the presented TLD from May 10th reported a 5 year survival of 5.7%or 5.8% in the external control arms. This is a very substantial difference and I am not sure I understand. My mother was in the trial and lived over 9 years from surgery. A glioblastoma did not return for over 7 years. This explains my interest and small investment. Thanks.
