done with DEX {for now}

DEX, or Dexamethasone, is a cancer fighting steroid. Jaxon had 2.3ml of DEX twice a day for the first 28 days of treatment. We met DEX again for a week at the beginning of August (3.75ml twice a day), and today we finished the second week-long "pulse" (3.75mg twice a day). DEX comes back into the picture again in December when he begins Long-Term Maintenance.


I say 'we' because it's really a joint effort to get him to take the meds. He's supposed to take an antibiotic (Septra) every Fri-Sat-Sun (for the entire 3 year treatment). Since it's been so much work to get him to take the DEX, I delayed the Septra by a few days. He started this week's course of that at bedtime tonight. DEX tablets were 3 pills of varying sizes in the morning and one big one at bedtime. I've learned that the liquid Ranitidine he has had to take with the DEX is actually just Zantac. We got that in tablet form as well and gave 1/4 of a pill with the bedtime DEX. Septra is half a larger pill every morning and evening for 3 days a week, usually on the weekend.

On his last round of DEX and Septra, he stopped tolerating liquid meds. I had to add quite a bit of other things to try disguise the taste and help it go down. It just got to be too much volume that he had to take in, and he started throwing them up right after drinking them, so we've switched to tablets. This has made things so much easier. I poke a hole in a jelly bean with a sharp knife and then shove the pill in. He takes one regular bean for every medicated bean. I've been extra vigilant with teeth brushing as he has 4 known cavities. Sorry to the Dentist, but the Oncologist wins on this one. I'm hoping that we'll eventually be able to transition him to swallowing tabs (maybe inside gel caps) so we can just get it over with! My friend who has a daughter with ALL a little older than Jax told me about this cool little straw - we might order a few of those. I know that in time, he'll eventually learn to swallow pills. The thing I struggle with is that I try to not make little things more difficult than they need to be, since he has to comply with so many "big things" and has no choice or control. I'm okay to try a few gimmicky things to make the transition easier for him (and for me!). Down the road he will have many pills to take, and we just can't be pumping so many jelly beans into him.

Yesterday, the boy ate ALL. DAY. LONG. While he was still eating one thing, he was demanding asking me what he could eat next. Sometimes while I was still preparing the previous request, he'd be placing his order for the next item. I wish I had documented everything he consumed. When I teased him about how he ate all day long he said "Mooooom ... you're giving me medicine that makes me hungry!" It's so strange to be forcing him to take meds that I know are going to radically change his behaviour and demeanour. He doesn't get angry about food so much, but if he doesn't get his way about where we are going and when, what we are planning or even just thinking about planning, what movie or game the boys will watch or play ... watch out! Now that he's had his last dose of DEX, the symptoms will gradually fade over the next few days.

He obsesses over food, but it is often an agonizing decision for him as to what he wants to eat. My suggestions are rarely accepted. Or, he wants one thing, and one thing only - usually something I've run out of or didn't think to stock in the fridge or pantry. Sometimes he thinks he wants something very specific but then when it's prepared and placed before him, he's lost the craving. There's something called "chemo tongue" - the meds change the taste of things. He's eaten a shocking amount of Mr. Noodles. Though I restricted him (and the other boys) to one package a day, we ran out. *gasp*

Yesterday alone, there was french toast (no crust), tomato soup (in the daytime and also in the wee hours of the morning), seaweed flavoured rice crackers, pumpkin pie, beef stroganoff (middle of the night), chunks of cheddar cheese, chunks of garlic sausage (no crust! I peeled the paper off, he just didn't like the outside part), grilled cheese sandwich (no crust, sometime close to midnight), milk, decaf tea with milk and a bit of sugar and plenty of stool softener (it's called PEG - he gets this every day), 8 jelly beans - 4 of them laced with DEX. I know I'm forgetting some. Pizza! He had pizza - no crust, just the toppings.

Today's tally ... before noon:
• One small square of PB&J sandwich, leftover from yesterday (no crust)
• 2 farm fresh eggs, scrambled with grated cheese and ketchup (did not finish)
• 300 ml milk
• Pumpkin pie (store bought, no crust, lots of whip - from a can)
• 200 ml cold water
• 2 seconds later ... "I'm still hungry."
• Nachos (did not finish)
• "While you're making the nachos, what can I eat?"
• Decaf tea with milk and PEG, aka "poo powder"
• "Mommy? I'm hungry."
• Me: "Let's do your medicine beans now so we can get it over with."
• Jax: "Ok. And then right after that I'm going to ask for something to eat."
• 6 jelly beans (3 with meds)
• Handful of cheddar flavoured rice crackers
• 300 ml tea + peg

We've run out of Mr. Noodles so he's persistently hassling me to go buy some. I'm not keen to take him into the store as he is quite fragile right now, feeling downright crummy. His ANC (absolute neutrophil count = immunity) was .38 last Monday, and I will be taking him for peripheral blood work tomorrow to see where he's at. We've been told to expect it to drop right down to nothing. Anything below .50 is considered "critically low", and we want it to be upwards of .75-1.5. Paul and the big boys are gone fishing for the day so maybe we'll see if Oma can go get us some groceries.

With his dropping ANC (due to the 3 doses of DOXO this past month), his energy level has rapidly decreased. He spends most of the day resting or lounging. He's put himself down for a nap in his bed twice this week.

His hair is falling out again, also thanks to the DOXO. Our oncologist said she has never seen anyone keep their hair after DOXO. It will likely be all gone within the next month, maybe sooner. The meds he'll get in the next few weeks also cause severe hair loss. It had started to grow again after he shed quite a bit during the first 6 weeks of treatment, but didn't lose it fully. This time it's just in time for cozy winter hats! I'm thankful for the cooler weather so I don't have to worry so much about him overheating or getting dehydrated. Much easier to keep warm than to cool off.

On Saturday night he started to complain of lower back pain. He was soon in agony, yet didn't want to take any pain meds (morphine) because he'd have to drink it (no tabs of that yet). "Mom, that stuff tastes AWFUL!" He conceded, and slept well until the meds wore off and his hunger woke him up at midnight. He started to have similar pain last night but it didn't get as bad as the night before. I spoke to the oncologist on-call at BCCH and he suspects the pain was likely caused by the DEX. That stuff is no joke!

Today is Day 22 of Delayed Intensification. Next clinic appointment is Monday Sept 8. He and I will stay at Jeneece Place the night before, as the appointment is early and he has to fast for a possible sedated procedure. The planned treatments for this day (Day 29) are count dependent. Blood work is first on the list and if he makes counts (ANC > .75 & Platelets > 75), he'll have an LP (lumbar puncture/spinal tap) to check his cerebral spinal fluid (CSF) for leukemic cells (this is done with every LP and has always been negative). After the fluid is drawn, he'll get more methotrexate injected in his spinal fluid (IT-MTX). If it's a go that day, he'll also begin 4 days in a row of an IV chemo called Cytarabine (ARAC). It will be done in the clinic in Victoria so he and I will stay those 4 nights at Jeneece Place. He'll stay "accessed" so there will only be one poke in his button on the first day, and the needle and short tube will stay in until he's finished the 4 daily doses. That day he'll also start an oral med (Thioguanine or 6-TG) for Days 29-42.  However ... if he doesn't pass his blood test on that day, we'll get a chemo break and try again the following week. We've been told to expect at least a week delay before starting DI Day 29. It is more common to have a delay than to go ahead as planned. Does that make sense? Probably not.

So if Day 29 is on Sept. 8 or 15 ... we'll have a 4 days of IV ARAC, 4 days off, then 4 days IV ARAC again. I'm considering going to Vancouver for the second cycle of ARAC, just for a change of pace and to see friends at RMH and our Doc at BCCH, but I'm not sure yet. My folks will be here for a week or two starting on Sept. 15 so I don't want to be gone for most of their visit (even though I'd be away in Victoria anyway). But if he has to wait a week or two for counts to climb back up, that might not be an issue. We shall see. We hold our plans very loosely around here.

I've rambled long enough. I'll end this with the great news that Paul and the boys did catch a big one! A 15 lb. Spring salmon off the shores of Parksville. When Jax heard they caught one, all he could think or talk about was how much he wanted to eat salmon. It was a few more hours until he got his wish, and in the meantime he had some chocolate chip pancakes. He also wanted some Kraft Dinner right before Paul and the boys got home. I shut that down pretty quick and he accepted my decision. Just barely.

The salmon was really tasty. Looking forward to more meals of that.

The Roadmaps - DI & IM2

The Six Stages of treatment for A.L.L.
Induction (4 weeks) *completed*
Consolidation (4 weeks) *completed*
Interim Maintenance 1 (IM1 - 8 weeks ending 8-07-2014)
Delayed Intensification (DI - 8 weeks beginning approx. 8-08-2014)
Interim Maintenance 2 (IM2 - 8 weeks)
Long Term Maintenance (2.5 years)

* Roadmaps for Induction, Consolidation, IM 1 detailed here. *


Delayed Intensification (DI) 56 days beginning approx. August 8

Jax will have peripheral blood work (from the arm, like a routine blood test) in Duncan, first thing in the morning on August 7 to see if his ANC and Platelets are high enough (ANC @ .75 and Platelets @ 75). Within an hour, we'll know if he reaches those criteria and will then immediately travel to Vancouver to begin Delayed Intensification at BCCH on Friday, August 8.  We need to go to BCCH for this procedure as our Oncologist in Victoria will be away on holidays, and there is no one else in Victoria who can administer the intrathecal methotrexate.  We have to be there for the Pegaspergase on Day 4 (Aug. 11) anyway, so it's not an extra trip - just a weekend at the new 
Ronald McDonald House in Vancouver!

If his counts don't reach the minimum required to begin this phase, we'll try again in another week.

This phase of treatment is aptly named, and likely to be the roughest stretch since the first 6 weeks.  He will receive a cocktail of 8 different chemo medicines over these 8 weeks, in addition to oral antibiotic (Septra) taken every Fri/Sat/Sun for the duration of his three year treatment, to protect against a certain kind of pheumonia that immunocompromised patients are susceptible to. 


He's going to feel really crummy. Two of the eight drugs in this phase are known to severely affect his ANC (immunity), which will reach all-time lows for several lengthy stretches. We will have to be extremely vigilant about any possible exposures to viruses and bacteria. He will most likely lose the rest of his hair. 

Day 1: *count dependant - ANC > 0.75 & Plts > 75 *
IT MTX (Sedated - Intrathecal Methotrexate)
IV VCR (Vincristine)
IV DOXO (Doxorubicin)
This will be a very long day, as the LP for IT MTX takes quite some time and the DOXO requires substantial hydration before, during and after administration, so that his kidneys can properly flush the medicine.

Day 4:
IV PEG-ASP (Pegaspargase)
This drug is known to trigger allergic (and other) reactions, and only certain hospitals have authorization to administer it. He has had it once before, on Day 4 of Induction, with no reaction. However, subsequent doses are more likely to trigger an allergic reaction.

Days 1-7:
Oral DEX (Dexamethasone)
Oral Ranitidine (to protect his stomach lining from the DEX)
Oral Liquid Sweetener ("Orasweet" - to protect his taste buds from the awful taste of the Ranitidine)

Day 8:
IV VCR
IV DOXO

Day 15:
IV VCR
IV DOXO

Days 15-21:
Oral DEX
Oral Ranitidine (to protect his stomach lining from the DEX)
Oral Liquid Sweetener (to protect his taste buds from the awful taste of the Ranitidine)

Day 29: *count dependant - ANC > 0.75 & Plts > 75 *
IT MTX (sedated)
IV CPM (Cyclophosphamide)
IV ARAC (Cytarabine)

Days 30-32 & 36-39
IV ARAC

Days 29-42
Oral TG (Thioguanine)

Interim Maintenance 2 (IM2) 

56 days beginning approx. early October
IM2 is almost identical to IM1, except that it has one additional IT MTX (sedated lumbar puncture/spinal tap).

Day 1 *count dependant - ANC > 0.75 & Plts > 75 *
IT MTX (sedated)
IV VCR
IV MTX

Day 11
IV VCR
IV MTX

Day 21
IV VCR
IV MTX

Day 31
IT MTX (sedated)
IV VCR
IV MTX

Day 41
IV VCR
IV MTX

Long Term Maintenance will begin on Day 57, or when ANC and Platelets reach .75 and 75. More about LTM in another post, as it gets a little bit complicated. He will be on one of four potential treatment protocols.

The Roadmaps - Induction to IM1

In the early days of Jaxon's treatment, we were given reams of paperwork to review and dozens of documents to sign. Part of the information we received is what they call in the biz, The Roadmaps. It's very official and medically written, but we've since learned how to make sense of it all. It outlines the medicines used in each phase of treatment, how they are administered (by mouth, IV, intrathecal ... ), what days they are administered, important notes for physicians, and what bloodwork or other tests are to be completed prior to, or after administration. 

Jaxon is on a treatment protocol for Average Risk Pre-B Acute Lymphoblastic Leukemia. (AALL0932).


The Six Stages of treatment for A.L.L.

Induction (4 weeks) *completed*
Consolidation (4 weeks) *completed*
Interim Maintenance 1 (8 weeks, ending 8-07-2014) *almost completed*
Delayed Intensification (8 weeks)
Interim Maintenance 2 (8 weeks)
Long Term Maintenance (2.5 years)

Induction (approx. 4 weeks duration, Diagnosis April 10 - May 14)

Day -2 (@ diagnosis) 
Complete Blood Count (CBC)
Under sedation:
Bone Marrow Biopsy
Intrathecal Cytarabine - IT ARAC (injected into spinal fluid)
Spinal Tap to check for cancer in his Central Spinal Fluid (CSF) *all clear!*

Every time he receives chemo into his CSF, a sample is taken to check for cancer cells.


Day 1 (Saturday, April 12, 2014)

Surgery to place Vascular Access Device (VAD)
This is used to draw routine bloodwork and to administer fluids and medication as needed.
IV Vincristine (VCR) 1.1mg 
Oral antibiotic (Septra) taken EVERY Fri/Sat/Sun FOR 3 YEARS! To protect against a certain kind of pheumonia that immunocompromised patients are susceptible to.

Day 4 - April 15
IV Pegaspargase (PEG-ASP)

Day 8 - April 17
(Bumped ahead by 2 days because the actual Day 8 landed on Easter weekend)
IV VCR
Methotrexate (IT MTX - sedated, injected into CSF)
Special bloodwork to determine response to chemo (Good results!)

Day 15 - April 25
IV VCR

Day 22 - May 2
IV VCR

Days 1-28
Dexamethasone (DEX) Oral steroid, a powerful cancer fighter
Oral Ranitidine (to protect his stomach lining from the DEX)
Oral Liquid Sweetener (to protect his taste buds from the awful taste of the Ranitidine)

Day 29 - May 8
Under sedation:
IT MTX
Bone Marrow Biopsy to determine response to chemo (Remission!) 
No further bone marrow testing will be required.

Consolidation (4 weeks, May 15-June 11)
Day 1 - May 15
IV VCR
IT MTX (sedated)

Day 8 - May 22
IT MTX (sedated)

Day 15 - May 28
IT MTX (sedated)

Days 1-28
Oral Mercaptopurine (6-MP)

Interim Maintenance 1  (IM1) 56 days began June 11
Begins only when ANC is at .75 or greater. His was .76, so no delay!
Day 1 - June 11
IV VCR
IV MTX (IV Methotrexate, given in escalating doses as long as ANC & Platelets reach criteria.
He began with 70 mg.)

Day 11 - June 20
IV VCR
IV MTX - 110 mg

Day 21 - July 2
IV VCR
IV MTX - 110 mg (His ANC was .60, so dose was not escalated.)

Day 31 - July 14
IT MTX (sedated)
IV VCR
IV MTX - 150 mg

Day 41 - July 23rd
IV VCR
IV MTX - 183 mg
He also had an ECG and an ECHO to get a baseline of his heart structure and function, as one of the drugs used in the next phase of treatment (Doxorubicin - DOXO) is known to affect heart function in some patients. Based on the small dose Jaxon will receive as part of his treatment, it is unlikely that he will have any heart issues down the road, but because it is a known side effect, testing needs to be done prior to receiving DOXO. His cardiac function will be monitored during treatment, and will be regularly tested for the rest of his life. 

We are now enjoying a chemo vacation, as there is nothing scheduled for the rest of this phase. He will have peripheral blood work (from the arm, like a routine blood test) first thing in the morning on August 7 to see if his ANC and Platelets are high enough (ANC @ .75 and Platelets @ 75). If he reaches those criteria, we will travel to Vancouver to begin Delayed Intensification at BCCH on August 8.  This needs to be done at BCCH as he needs an LP (Lumbar Puncture to administer IT MTX) and our Victoria Oncologist will be on holidays. We already knew we would have to be at BCCH on Day 4 of DI for Pegaspargase, so we're just going a few days early and making a weekend out of it. We've booked a room at the new Ronald McDonald House!
