Just came back from the latest MRI (which stands for "Most Reasonable Interpretation"). The white spot basically looks the same as the last time. There's still a little more information to gather, but for the most part, I felt good about the results. The next likely step is to get back onto the trial as soon as my liver cooperates. This will hopefully be confirmed tomorrow after Dr. B presents at the Tumor Board and my blood test returns negative. Of course, I'm still in "monitor mode" and will likely have another MRI in 4 weeks or so. However, it is possible that this "thing" will stay dormant for a long time, and I would be perfectly accepting of that as long as it doesn't impose itself!
Overall I guess it was not quite as good as I'd hoped for, but WAY better than I envisioned!
