SIRT and Irinotecan

We have just arrived home from the Ivy suite where Joan received her 'Push' of Flourocillin after yesterday's SIRT therapy. Earlier this morning she had a Gama Ray Camera investigation to see if any of the SIRT irradiated spheres went where they should not have. The Man told her that they all reached their target(s), the 30 something tumours in her liver. He was pretty satisfied with the procedure. From that hospital we went to see Joans oncologist at St John's at Subiaco. He wasn't terrible demonstrative about SIRT and pointed out that the tumours had progressed. The next CT scan is in two months, but next week's blood test and visit should, we hope, show a significant lowering of the CEA, the tumour blood marker. He has her scheduled to restart a new form of chemo in three weeks to keep the lung tumours at bay. They have grown since Joan finished chemo almost two months ago. The new one is Irinotecan. Hope the side effects don't hit too hard as Helen's wedding is on the 18th of December. The Onco thinks it should be OK.

The Oncologist told us that the SIRT radiation only penetrates about 1.5 millimetres into the tumours. We don't understand what that means as the tumours are not spherical. Where does does the blood vessel enter the it's widest point or the thinnest part?
We have a lot to learn before we start our own medical practice!
