Interesting news! This is the second time in a row that Jonathan's bone marrow aspirate (BMA) tests came back negative. This is indeed a good sign - although I'm too numb to know whether I should be happy or not. I think I don't hear enough (or any stories) about neuroblastoma survivors who have either not gotten a relapse and have lived to be an adult or survivors who may have had a relapse and is still able to live to be an adult. My mind is too full of stories of neuroblastoma patients who are declared free of disease but develop a relapse - even after the major five year window has passed. The only consolation I will have is that while Jonathan is declared 'free of disease' we will have a period of not having to do any treatments. The only problem is that we could get lulled into a false comfort zone and hearing that he has a relapse later on would just be devastating. I still haven't decided whether I will fight again if he does have a relapse. I went through a period a couple weeks ago in which I was thinking that if his disease ever gets worse - we would do comfort care. But, like all things, I'll cross that bridge when I reach it.
Although he has had a second negative result for his BMA - there is still one item that needs to be cleared up. What follows is the text of an email from Jonathan's primary oncologist on her thoughts on his latest re-evaluation results.
The bone marrow was negative again - even with the synaptophysin staining - so we are 2 for 2 with clean results, which counts as a 'real' response to fenretinide, as defined by the study requirements - so that's great!
The MIBG scan is also probably fine, but there was a small spot of uptake that appears to be in either in the liver, possibly the gallbladder, or possibly retained within the bowel. they needed to get SPECT images at 48 hrs to get a better view of it and unfortunately we couldn't get those pictures because they take longer to acquire & he couldn't hold still without anesthesia for that long. When we went back & looked at his last few MIBG scans, this spot may have been there before, but it was chalked up to bowel activity (intestine running along the bottom edge of the liver) which is normal (the MIBG gets excreted via the bowel). But the fact that it is present on several scans when you go back & line them up is both a little concerning and a little reassuring: active tumor usually does not stay exactly the same size over the course of months (that's the reassuring part) but its annoying that we have this spot now that we don't quite know what to make of. Also reassuring that nothing abnormal shows up on the regular CT scan. So to try to settle things, the next time he gets an MIBG scan we will do a special study called an MIBG/CT, where they get CT images at the same time as the MIBG & fuse the images so we can get 3-D localization of the spot that is hot on MIBG. this test does not take the place of a regular CT scan, it just helps localize anatomy on MIBG scanning.
So its all good news so far, with the caveat that we need to sort out this finding on the MIBG scan & we should be able to do that when we re-image him after the 6th cycle of fenretinide.
Jonathan has just finished his fifth cycle of the fenretinide drug and to date - he has had no visible or apparent side effects. I'm so accustomed to having Jonathan go through some sort of 'hell' when receiving medicine that can threat him that it's a little strange to go through no hell with a drug that is suppose to help treat him. I'm almost in disbelieve that this drug might actually be working - especially since everything is in an oral form and it's something we've been giving him at home. I know we are slowly approaching our two year anniversary of fighting this disease and I'm curious to see whether Jonathan will be declared in remission when we reach that anniversary or not. Regardless, I want to mark this anniversary with a special event - but I haven't figured out what it should be. All in all it has been an interesting two years and I'm curious to see what 2007 would bring for us.
