We seem to have escaped the nasty side effects of the last high dose methotrexate this time, thankyverymuch. Minor bumps on his face, an itchy scalp that might even be attributed to the hair growing back so thick and fast Daniel is almost not bald anymore, definitely some nausea and definitely some mouth sores, but not so bad he can't at least manage fluids as long as they are non-acidic. Since the infusion didn't get started until twelve hours later this time than last time, I waited an extra day to proclaim us free from the misery that was two weeks ago, but I think by now, we may be officially in the clear. The ped onc who saw him while inpatient was skeptical that what he had last time was actually side effects of the methotrexate alone, and we were skeptical that it wasn't, but again, it appears the doc was more right than we were. Fancy that. He probably had an existing allergic reaction of some sort going on that was inflammed by the methotrexate further stressing his body. He did go in with a bit of a rash last time that they attributed to the possibility that his three weeks of being off chemo and his body taking that opportunity to do a little detoxing, the effects of which may have been coming out of his skin. Whatever the cause that was absent this time, we'll take the effect. He's been grouchy, has taken to flinging things that frustrate him and swinging things, like broom handles or a whip-like length of hot wheels track at us for no apparent reason, which leads to us having to stop and reset the mood, convincing him to kiss away the owies he inflicted, holding him until the anger and frustration passes and he can process things logically again.
Grandpa Danny was here for a week, and Aunt Marci over the weekend. I don't have any pics from the weekend, but I do have this one from Tuesday evening, whenwe took Chinese takeout to the splash park for a germ-easy evening out of the house. Maybe it's just my imagination, but it just seems like there are fewer germs and viruses lurking outside where the fresh air and sunshine can get to them.
Lookit all that hair! It'll probably fall out again in the next phase, but the chemo we are on now is less of a hair-losing one. I'm obsessed with rubbing his head right now. He is less than impressed by this sometimes.
Daniel is such a man's man, obsessed with the men in his life, grabbing them by the hand and dragging them around the house to show them his toys and dictating exactly how to play with them. Grandpa Danny got to experience this for several days after we finally escaped the hospital after our 4.5 days there. Aunt Marci got a taste of this little dictatorship over the weekend, when he took to simply placing his hands on the backs of her legs and "driving" her around the house and yard to do his bidding.
He actually has started being okay with eating again, as long as it is food that doesn't burn his mouth sores. Orange juice, tomatoes, salsa, out. Eggs, cheese, bread, bananas, in. Unfortunately, low acid often also means low fiber. And cruciferous vegetables are a no go lately, I assume given his changed taste buds. He can't tell me if he has the dreaded chemo-induced metallic taste in his mouth that makes almost everything taste disgusing in varying degrees, but I think it is obvious he has at least some degree of change in his ability to experience flavor normally. If you think a normal toddler's palate is a moving target, try adding a chemo regimen that turns even adult's palates back into those of toddlers.
We finally had the opportunity to have Daniel's first physical therapy appointment yesterday that we started working on back in May, before he was walking yet. As fabulously as I thought he was doing, compared to how he was doing before, his therapist's much sharper eyes caught some things my jaded eyes missed. Like the fact that oddly, he is using his once-broken leg more heavily than his non-broken one, with the foot on his non-broken leg being the one that is more pidgon-toed. Not to the point of needing a brace, but she did recommend going back to the orthopedist and having custom inserts put in his shoes to try to correct his collapsing arches and help his stumbling, which may come from some chemo-induced neuropathy or may just be him. He learned to walk at a year, right on-target, but after that dropped behind as far as learning to run, even before he broke his leg, which may have been due to the disease slowly sapping his energy or causing discomfort, or may have just been an inexplicable delay. I personally think it might have been due to the giant upheavals we've experienced in the last year- as hard as we tried, his security became as moving a target as his taste buds are now. He started walking in January, and by May we had sold our business, by June we hit the road and our home was our camper for the next two months, in August we were yo-yoing back and forth between Kansas and Nebraska, Bobby bouncing in and out of our lives unpredictably. Then Bobby started his job here in Northern Colorado, and we didnt follow him here until almost two months later. Then we had a rental house where everything was unfamiliar, and mama all pregnant and hormonal, and Daddy working legitimately crazy hours, at the same time the leukemia was taking over his body, making him feel tired and irritable all the time. And just as things might have been getting back under control for that last month or two before big mama popped out another baby, boom. Broken leg. Kid's due for a break. Whatever the toddler equivalent of a week on the beach might be. Probably a week or two of his parent's full, undivided attention.
After a lot of googling, I think I have finally located the treatment protocal Daniel is on, or at least really close. This is copied and pasted from http://www.ped-onc.org/diseases/ALLtrials/COG0232.html and heavily edited by me, acronyms spelled out, and non-relevant arms of the trials deleted.
Note: this outline was patched together from the NCI online protocol and input from parents of kids with ALL. It is summarized here for our convenience, so that we can quickly compare our protocols. We do not guarantee the accuracy of this outline - it is not an official document. You can contact your child's oncologist and ask for the complete protocol document if you are interested in the details of your child's protocol.
All newly diagnosed ALL patients are enrolled in COG AALL03B1, Classification of Acute Lymphoblastic Leukemia.
At diagnosis of ALL, the oncologists at the local hospital determine an initial risk classification as follows:
At diagnosis samples of blood/bone marrow aspirate/Cerebral spinal fluid are taken and studied for cytogenetic/immunophenotype characteristics.
High risk ALL is treated on AALL0232, as outlined below. Standard risk ALL is treated on AALL0331. The protocols for infant, T-cell, and very high risk will be added to this site when they are available.
What is high dose methotrexate?
High dose methotrexate (HD MTX) is 5 grams/m2 administered by IV. Leucovorin rescue is used and begins 42 hours after MTX treatment begins and continues until the MTX is cleared.
Why dexamethasone vs prednisone?
Dexamethasone seems to work better but has serious (and potentially long-lasting) side effects, prednisone is less toxic. This study aims to find the optimum steroid dosage.
Induction, 4 weeks:
cytarabine intrathecal (IT) on day 1
vincristine IV on days 1, 8, 15, and 22
dexamethasone oral or IV twice daily on days 1-14
methotrexate intrathecal (IT) on days 8 and 29
pegaspargase intramuscularly (IM) once on day 4, 5, or 6 (Daniel sort of tolerated this dose).
Consolidation (about 7-8 weeks)
cyclophosphamide IV over 30 minutes on days 1 and 29
cytarabine subcutaneously on days 2-5, 9-12, 30-33, and 37-40
mercaptopurine (oral) on days 1-14 and 29-42
vincristine IV on days 15, 22, 43, and 50
pegaspargase IM on days 15 and 43 (Daniel had a small reaction to the first dose, then had his big reaction to the second one, necessitating his 12 shots of Erwinia Asparaginase over two weeks to replace it.)
Intrathecal (spinal) Methotrexate on days 1, 8, 15, and 22
Interim maintenance I
vincristine IV and high-dose methotrexate IV over 24 hours on days 1, 15, 29, and 43
leucovorin calcium IV every 6 hours for at least 3 doses, beginning 42 hours after start of each Methotrexate infusion
oral Mercaptopurine on days 1-56
Intrathecal methotrexate on days 1 and 29.
Delayed intensification(s)
vincristine IV on days 1, 8, 15, 43, and 50
oral dexamethasone twice daily on days 1 to 21
doxorubicin IV on days 1, 8, and 15
pegaspargase IM on day 4, 5, or 6 and day 43
cyclophosphamide IV on day 29
cytarabine IV or SC on days 30-33 and 37-40
oral thioguanine on days 29-42
IT Methotrexate on days 1, 29, and 36
After delayed intensification I:
SER (slow early responder) patients proceed to interim maintenance II and delayed intensification II
RER (rapid early responder) patients proceed directly to maintenance
(Note that Slow Early Responders (like Daniel, with more than .01% leukemic cells left in their bone marrow after induction) received two delayed intensifications.) Either our nurse forgot to mention Daniel's second delayed intensification, or he will only have one. So far, from what we understand, his treatment plan is:
Induction, 1 month
Consolidation, 2 months
Interim Maintenance I, 2 months
Delayed intensification, 2 months
Interim maintenance II, 2 months
Maintenance, 3 years
Interim maintenance II
vincristine IV on days 1, 11, 21, 31, and 41
MTX IV on days 1, 11, 21, 31, and 41
pegaspargase IM on days 2 and 22
MTX IT on days 1 and 21
Delayed intensification II
Same as delayed intensification I
Patients then proceed to maintenance therapy.
Maintenance therapy
vincristine IV on days 1, 29, and 57
oral dexamethasone twice daily on days 1-5, 29-33, and 57-61
oral MP on days 1-84
IT MTX on day 1
oral MTX on days 1, 8, 15, 22, 29, 36, 43, 50, 57, 64, 71, and 78.
Maintenance therapy repeats every 12 weeks until total duration of therapy is 2 years from the start of interim maintenance I for female patients and 3 years from the start of interim maintenance I for male patients.
Patients are followed every 2 months for 2 years, every 3 months for 1 year, every 6 months for 1 year, and then annually thereafter.
