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!

REMISSION!

It was right around suppertime, exactly 4 weeks ago, that we were given the news that Jaxon has ALL. 

Around suppertime today, we were told that Jaxon has achieved complete remission!

My facebook post:
Complete. Remission. Achieved!

From Paul:
Bone Marrow results are back ... Zero. Negative. None. Gone. Bye-bye.
In other words, no traces of Leukemia present and we are onto phase two of the process. Can I get an AMEN People!!!

We still have a very long road ahead. The battle has really just begun. The treatment over these past four weeks, the Induction phase, has done as it was designed and expected to do - to eradicate the Leukemia from his cells. We will soon begin the next phase, called Consolidation. We will learn more about it from our Oncology team over the next few days. 

Other really big news of the day is that Jax finally got out some air and other stuff that has been trapped in his lazy gut. Docs have been watching his abdomen closely, as it has been causing him great discomfort and has often looked distended. He went for a third x-ray of his belly today. The scan showed that he had a considerable amount of air, and though it wasn't clearly seen on the scan, it is believed that he has some impacted stool. I'll spare you the details. We know that his bowels are working at a basic level, but he won't be discharged until his poops normalize and the cramping/bloating subsides. He's had some pain again when he pees. They are still working on the theory that there has been some injury to his kidneys. A combination of the dehydration and a suspected stone or crystals. Both the pee and poop issues are expected to resolve on their own. After the results of the x-ray came back late this afternoon, there was talk of him getting an NG tube to alleviate the pressure on his gut. He must have gathered all the details he needed to know about that as shortly after he spent a long and very successful time upon the throne. Who can tell me why all the toilets in this children's hospital are built for adults? So tall and imposing. Horseshoe shaped seat. My boy's little bum and chicken legs just don't do well on such a monstrosity. PZ went and bought a cheap training potty. It sits on the floor beside his bed so we don't have to get him, two supporting adults, and his IV pole into the tiny bathroom with the giant toilet. In the training potty, he can have his feet on the floor and sit comfortably. There was added complexity this evening when docs ordered a urine analysis (to be caught midstream, thank you very much) and a stool sample. They must not be mixed. We rigged up a system on the big toilet, with the removable seat from the training potty.  The nurse was very impressed, and our efforts were "rewarded". He has been returned to NPO (no food or drink by mouth) status, though if he's really hungry or really thirsty, he can have some clear fluids. This is to ensure that the gut continues to awaken and work its magic.

Our sweet nurse Marina just came in to give me the results of the Electrolyte and Metabolite portion of his blood work from this evening. Everything is as it should be, no "flags" to show that any of the levels are out of the normal range. He could still be passing crystals or sediment, but the numbers show that his kidneys are functioning perfectly. 

I don't really want to end this post talking about bodily fluids ...

The cancer is gone. Now, let's keep it that way.

Thank you, Loving Heavenly Father. Our helper, our healer, our hope.

Admitted: May 8

From the very beginning of our treatment here at BCCH, we have been looking forward to this day, "Day 29" of his treatment plan. The real 29th day of his treatment will be this Saturday, May 10th. The clinic is not open for procedures that day, nor will it be open tomorrow because the clinic will be closed for a department-wide conference/training/development day. So today, Day 27, he received his "End of Induction" procedures - a lumbar puncture (LP) to extract spinal fluid to check it for bad cells, and a bone marrow biopsy, to ensure that the first phase of chemo was successful to bring him to remission.

He has had 3 LPs in the past 4 weeks. The first one was on the very first day we arrived at BCCH. It was done to check his cerebral spinal fluid (CSF) for cancer cells, and to inject chemo (intrathecal cytarabine, IT-ARAC) directly into the spinal chord as a precaution, in case the cancer was present there. He had another of these procedures done on Day 8, this time receiving intrathecal methotrexate (IT-MTX). Both times, there have been no signs of cancer in his CSF. It is expected that this test will continue to show negative results. Today he received his second dose of IT-MTX.

As today is not officially the 29th day, he will need to have 3 more doses (morning and bedtime on Friday, and morning on Saturday) of DEX, a powerful cancer fighting steroid . DEX really does a number on kids emotionally and physically.

7:54 am
Clinic procedure appointment at 8:00 am, as planned!

8:42 am
His procedure just started, will be done in about 15 minutes. Some results will be available throughout the day, others by end of tomorrow.

8:46 am (Paul)
When we arrived here at BCCH exactly four weeks ago, we started off in Room 5 in the Oncology Clinic/Intake Ward. On this (hopefully) last day of "Induction" we are in the same room. Full circle. We sat in this room wondering what was wrong with him a month ago and today we're hoping to hear that the bad is gone!

The procedure went well. The first thing he said when he woke up was "NOW can I have some Rice Krispies?"

He's been having some issues with pooping since the onset of his dehydration. We were quite happy to hear that he pooped a bit during his procedure, as it showed that his "lazy gut" was awakening. He pooped lots today, though we are still waiting for more gas and stool to clear his system. Poor little bubs ... his itty bitty body has been through so much.
