Bumps Along The Road

Claire began "focal" radiation treatment on January 28th. I had mentioned that there were concerns regarding the tumor progression. Claire's tumor is growing at a very quick rate and showing signs of the aggressive nature of pediatric PNET brain cancer. Although the location of the tumor recurrence has remained local, there are problematic changes. There is a visible extension of tumor into an area of the brain that circulates CSF(cerebral spinal fluid). The concern is that this presents a high chance for dissimination into distant areas of the brain. There is also a visible opening from the tumor/surgical cavity into a ventricle (another pathway for CSF fluid to circulate throught the CNS). The UCD radio-oncolgy doctors began treating Claire with the focal radiation treatment we wanted, but expressed a major concern on outcome due to tumor progression. When UCD agreed they were reviewing MRI film from Claire's last scan in early December. The scans that were taken on December 26th in preperation for treatment showed the questionable progression. UCD allowed Shannon and I some time to seek other opinions, including the Sutter Team who have been involved from the beginning. After much thought and research, we have agreed to move to Full Cranio/Spinal Rt therapy. We have done everything in our power to avoid it due to the consequences on a young brain. The facts and biology of recurring PNET tumors have forced our last hand. If we were to continue with focal rt and the tumor dissiminated (spread) we would have no more options. The size of Claire's targeted "focal" field is very large eliminating any opportunity to provide additional RT to other parts of the brain if the tumor spreads.

In no way are we viewing this fight over. Claire's tumor has not behaved as typical PNET. She did not recur until 15 months from presentation. The tumor has remained a "local" problem. She is with us at 18 months. But we could not ignore the recent aggressive growth and behavior of the disease. Claire has been so amazing and has displayed such a will to stay with us that we were comfortable with this decision.

In the next few day's, Claire will go through the process of preparing for the full cranio/spinal treatment. On Friday she will complete the initial boost dose to the tumor area. Next week she will begin the 5 week whole brain/spine treatment. UCD has agreed to treat her with a lower than standard dose for the full brain/spinal segment. There are ongoing studies utilizing a lower dose to the full brain/spine in an attempt to limit cognitive and other damage.
