Re: Neoadjuvant therapy, liver transplant effectively treated perihilar ch
this study largely based on the data by the Mayo clinics experiences because about 67% of the patients is from one center (he did not say where but mostly is Mayo clinics,) the link of the abstract below provided the clue.
That means 33% of the data came from the other 11 centers( 3% of patient data from each of the 11 center).
Look at the conclusion, the overall 5 years suvival is down from 68% to 65% after the addition of patients from the other 11 centers. Still pretty good if you can qualify for the liver transplant.
