[Edit] Some photos from the James Fund Neuroblastoma Family Retreat
It’s been an interesting week, this past one. Not one which I would like to repeat. In the past two 1/2 years, we’ve learned a lot about cancer. After all, it has become the central theme in our lives. It has also become part of many of your lives as you have followed us through our journey. Shall we say that we’ve become comfortable? Perhaps not comfortable, but used to it.
Having to deal with MDS has certainly mixed thing up. Neuroblastoma seems so… yesterday. We know nothing again. And so, the researches have begun again. One major difference is neuroblastoma is a pediatric cancer. MDS/AML is (to be grossly general and possibly inaccurate) more of an adult disease. In other words, there is very little literature on pediatric secondary MDS/AML. To put things in context, consider that:
o neuroblastoma hits 1 / 100 K kids.
o 2 to 3 % of children will develop secondary (therapy induced) cancer.
o So, we’re talking about less than 2 or 3 children out of 10,000,000 kids develop MDS/t-AML.
these are incredible odds, in line with winning a 6-49. I think the odds for 6-49 is 1 / 14 M. Yes, Maya is a very special child!
In this not so brave new world, blood is what’s on our mind. Specifically, we are focused in the white blood cells and platelets. White blood cell and the immature white cells (blasts) are of concern to us. It will increase and over crowd the bone marrow as MDS progresses into AML. The marrow becomes compromised as a consequence. Maya is not producing any platelets and hence CBC and platelet counts are what we now focus on. Neuroblastoma has taken a back seat for now.
This Thursday afternoon, after getting a CBC done at sick kids, Dr. Cada asked to speak to both of us immediately. We arranged a meeting expecting the worst. And the news came to us as a big surprise. Maya had approx. 40% blasts in her blood. By definition, 25% blast in her blood (AKA peripheral blood) is classified as AML or in our case t-AML. The marrow failure team (sub-umbrella of Haemotology group) was quite concerned at this spike and classified Maya now, as having progressed to t-AML in a rather dramatic fashion. Typically, MDS does not progress so acutely. The implication was that our plan of keeping Maya on Vidaza was now off the table and the only course left to us was a BMT… if BMT team thought that the second BMT might be beneficial for Maya. Until today (friday afternoon), an offer for a second BMT was not confirmed. This news was a complete shock to us. How can she look the part of a healthy child, yet be so, so sick?
In order to confirm the progression, an emergency bone marrow aspiration was requisitioned for this morning. And Maya underwent another BMA in a week. Indira and I had a very disturbed evening Thursday night. The only course of action left to us is a therapy that may kill Maya. Indira and I decided that Maya, as per her wish should have an early birthday party.
This afternoon, it seemed that most of the Oncology/Haemotology team met and discussed how to proceed with Maya. As Maya was the first child for BMA, by the time that the team met, some of the BMA results were available for the team discussion. Subsequently, we were given the summary of the team meating. This meeting was represented with two marrow failure physicians, BMT physician (One of my fav… she’s just awesome) as well a couple of nurse practitioners and the social worker. So, here we were, surrounded by a small regiment of sick kids staff.
It turns out that on rare occasion, marrow will dump out a colonal mass of blasts into the peripheral blood. This result is of concern, but in Maya’s marrow, the blast count was found to be 17%. In other words, we are not classified as a t-AML patient. We are still MDS. The results were infinitely better than what we anticipated.
Both Indira and I had dipped into our respective hell for 24 hours. We haven’t been so shaken up since the early days of neuroblastom therapy. While we appreciate the immediate response from Sick Kids, and it is really the right thing to do, believing that we were now dealing with t-AML was one of the most stressful period we’ve had in a long while. It’s not far off from having to walk into a mine field where there are no tracks at all.
As we were all gathered in one room, we took the opportunity to ask questions and have a frank discussion. Here is the summary:
o 40% blast in Maya was very worrisome. The only way to confirm is through a bone marrow aspiration.
o BMA blast count was found to be at 17%. Therefore, we are still MDS.
o BMT team is willing to consider a second transplant. The conditioning regiment (high dose chemo agent) is still to be decided. Busulfan and Melphalan is still on the table as an option, with use of defribotide in the prophylactic role.
o No matching donor was found. Therefore, the only option is to either use Maya’s own stem cells:
– we can use the peripheral stems cells which we’ve collected from the first BMT. We still have a lot left from the first transplant.
– We can also use the cord blood stem cells which we’ve banked when Maya was born. Use of cord blood stem cell is thought to be the best option at this point.
– We can use Indira’s blood in a haplo transplant. We then would need to deal with the possibility of “Host Vs. Graft” disease. Mother’s blood does better in a child.
– The main concern with using Maya’s stem cell is whether there is a predisposition for Maya to relapse. In other words, is Maya genetically predisposed to leukemic diseases and this is why Maya developed AML? If this is the case, using her own blood (autologous stem cell rescue) would not be advisable. If Maya is predisposed, haplo transplant from Indira would be the next best option. While we are testing for leukemic predisposition, the results won’t be available for another couple of weeks. Had Maya progressed to AML, autologous BMT would not be advisable as the possibility of relapse would be significantly higher.
– Bone Marrow Failure team at Sick Kids like to proceed with BMT rather than wait. And should we give our concent, BMT is ready to proceed.
BMT Doctor was kind enough to talk to her colleagues about Maya last week at the COG conference. So, we do have collective knowledge of the bone marrow oncologists across the world. So, this additional information will be helpful to us.
However, I requested a bit more time so that I can follow up on AML research. Land mines are everywhere. My response to the doctors were as follows:
o Frankly speaking, there’s very little exposure at sick kids on t-AML. For that matter, there hasn’t been enough cases of pediatric t-AML around the world to build a significant knowledge base. If there are centres that have dealt with more cases of t-AML, we would like to talk to them and possibly have sick kids refer Maya to this centre. The gravity of our circumstances warrents physicians with theoretical understanding versus “medical art”
o One centre that may stand out is Saint Judes in San Diego. They seem to have more clinical trials in leukemic diseases. It is also one of the centres where our BMT doctor will talk to this coming week.
o We will convene next thursday to discuss treatment options.
Our thought presently is this:
o BMT is the only curative therapy. It is also very high risk. There is 45% and 40% change of complete cure using autologous and allogenic stem cell rescue is used, respectively. If there is a relapse? Third BMT? I don’t believe that Sick Kids would agree to it. I don’t think we would either.
o Vidaza can keep MDS in check for some period of time. However, one does not typically see any response from the use of Vidaza until 6 – 12 rounds, which translates into 6 – 12 month cycle. So, we would not really know if Vidaza is working for a while.
Use Vidaza –> does not work. Full stop. Goto BMT.
–> MDS is stable. stay on Vidaza until we start to see progression. Goto BMT.
Use BMT –> It works. Maya is cured of t-AML. Proceed with DFMO, if this treatment option is still available to us.
–> It does not work…
What we’re looking at is the optimal time frame when we should apply the treatments. Here’s an example. Suppose Vidaza keeps MDS in check for 12 months for Maya. Going into BMT now rather than use Vidaza would mean that we’d be taking 55% chance of shortening Maya’s life to a couple of months. Complication may kill her within 2 – 4 weeks of starting BMT. It’s a significant risk to accept.
we will have another follow up meeting next Thursday to discuss a plan of action.

We expected them to confirm the progression and the discussion to be about how to proceed with BMT.

We will need to look at the details still. After all, the devil is in the molecular level details. We will have another follow up meeting next Thursday to discuss a plan of action.
With the scare of our lives behind us, we decided to go to James Fund Neuroblastoma Family retreat. Taylor came with us, this time around and we all had a great time. Being with the families who deal (past and present) with this aweful disease is … cathartic in nature. They, we, all understand the tribulations we all face in multiple dimensions.
This weekend, we had a lot to be thankful for. Thankful to Syd and Diane (James Fund), the volunteers, the families, the camp but most of all, we are grateful to have the kids really enjoy themselves. Picutures will be posted soon.
