Dear Cynthia:
Here is the way that I usually approach this issue. Yes, 40% of
insulinomas recur in about 10 months or so. However that leaves
about a 60% cure rate.
Now if we assume that one month in a ferret's life equals about one
year in a human's life, let's make an analogy with you (nothing like
getting personal). If someone told you that you had a tumor, and
removing it surgically would ensure you a minimum of six years tumor-
free life, more likely ten years, and there would be a 60% chance
that you would never be bothered by it again, what would YOU do?
Additionally, when combined with partial pancreatectomy, the average
tumor-free interval jumps to about 12 months (published paper I wrote
with Charlie Weiss years ago in JAAHA.)
With kindest regards,
