The results of the MRI were not good. The tumor is larger, more involved with the spine, growing into the nerve route and starting to push on his right ureter and kidney. They can definitely tell that the tumor has been continuing to grow through this last round of chemo. Which means we are back to square one in Alan's treatment, again.
Doc H2 brought up three options for systemic treatment of the cancer. First, is a more experimental treatment - oral Cytoxin (Alan had previously had IV Cytoxin as part of the VAC protocol) and IV Vinorelbine, which has been used for rhabdomyosarcoma but there is no data on how well/if it works on unclassified sarcomas.
Second, he works to come up with a new custom cocktail of drugs, taking into account the biology of the tumor.
Third, we look for a clinical trial. Of course, this would mean a delay in starting the treatment while we look for applicable studies and get Alan qualified.
On the surgical side, Doc L had suggested
cryoablation, where they would make a small incision and insert a needle into the tumor and inject it with something to freeze it to death. The inpatient recovery time would be fairly quick, just an overnight stay in the hospital. Doc H2 and Doc L will both talk to two different
interventional radiologists to see if they will take on Alan's case.
Any surgical option will be almost pointless without a systemic solution to the cancer. Otherwise it would be like pruning branches off a tree with strong roots - the branches will just keep growing back.
So we'll take the first option for chemo back to Doc P to implement while the docs at MDA pursue the cryoablation.
Of course this was devastating news. We had high hopes that the chemo was working since we had finally seemed to get a handle on Alan's pain. Doc H2 said that if it was working, we wouldn't be needing to use the Fentanyl patches at all. He had called Doc P give him the results, and Doc P asked him to continue pressing the radiation oncologists to look more closely at Alan's case.
It was a short visit with Doc L to answer any questions we had about the cryoablation and to discuss removing the hip brace from the AFO. The two surgical options she considered were the cryoablation and
radio-frequency ablation. Because the RFA heats up the tumor (not optimal in such close proximity to Alan's organs) and has not been regularly used in pediatric patients, she opted to pursue the cryoablation instead.
Rather than leaving right away as planned, we met up with the Smit's after our appointment with Doc L in the hospital lobby to process this latest news. They had been told by doctors back in South Africa that there was nothing they could do for Tristan, so they certainly understood what it was like to receive devastating news, and it was good to be able to lean on them for a while. The doctors still have treatment plans to pursue, so we aren't giving up hope.
