Noah's Dad

We’re on day 19 of induction 2. Noah’s ANC has been at zero for 7 days now. This is about the time I started getting concerned last go-around, but have a much different mindset at this point.

First, we’ve seen his ANC hang at zero before and it eventually went up. Last round it actually took over 30 days to start inching up which was…stressful. If that happens again, so be it, but there are signs that it might come earlier.

We saw some of these same “precursors to ANC coming up” last time too that maybe gave us a bit of false hope: a couple monocytes here, an eosinophil there, a nightly slight rise in temperature (99.5). But each morning we’d get up and ANC was still stuck at zero. And all throughout that time, Noah “looked” pretty good. Again this time, he looks good. He’s a little bit chubby because he’s been eating a lot. He drinks and pees like a racehorse. He does some workouts that are beyond what I ever expected a kid 10 days off chemo would be doing.

But, more notably, he received a red blood cell transfusion last Sunday morning and platelets the next morning. The red blood cell transfusion took him from 6.5 (always transfused <= 7) to 9.7. That dropped about 0.3 each day since, except for today it held at 8.6. It’s possible that continues to hold. The platelet transfusion took him from 16 (always transfused <= 20) to 61. Within two days that dropped to 32 and we assumed the next night would be a transfusion. But it wasn’t; it was 35. And the next night it was 38. Today it was up to 59. We’ll see, but it sure looks like that one is producing on its own.

So now we wait. Regardless of whether he recovers quickly or slowly, he’ll again have a spinal tap and MRD (measurable residual disease) test on or just after day 28 to see what remains. At the moment, things are good and we celebrate the good times.

A few other notes:

  • Noah received the Student of the Month award for his elementary school this week. This was presented during a school board meeting and the principal FaceTimed Noah in and shared some very kind words. All of his former teachers also wrote about him in a document delivered with the award and it all meant a lot. We’re just really thankful for this school and such a caring staff.

  • You’ll also note the picture below where Noah is NOT wearing a stocking cap. I probably pushed him too much early on to embrace the baldness. It was going to happen naturally anyway as he got used to it. I’m not sure he’s fully stoked about it yet, but I can promise he would not have agreed to this picture a month ago.

I’m going to sign off since it’s 11pm and I think my screen is keeping him awake! We love you all and over and out.

Terms in This Post

MRD (Measurable Residual Disease) Testing

A sensitive test that can detect cancer cells at very low levels (as few as 1 in 10,000 cells for AML). Used to determine if a patient is in remission. The threshold for remission is fewer than 5 abnormal cells per 10,000.

LP / Lumbar Puncture / Spinal Tap

A procedure where a needle is inserted into the lower spine to collect spinal fluid and deliver medication. Used to test for leukemia in the CNS (central nervous system) and to deliver chemotherapy directly into the spinal fluid as a preventative measure. Noah receives after each phase of the treatment.

ANC (Absolute Neutrophil Count)

A measure of neutrophils, the white blood cells that fight infection. Normal range is 1,500-8,000. Below 500 is considered severely neutropenic with high infection risk. After chemo, Noah's ANC drops to zero and we wait for it to recover, which can take weeks. Calculated as: WBC × (% neutrophils + % bands) / 100.

AML (Acute Myeloid Leukemia)

The type of leukemia Noah has. It requires aggressive, in-patient chemotherapy treatment. AML is less common in children than ALL. Typically 4-6 months of intensive treatment — usually 4-5 cycles of inpatient chemotherapy, each requiring roughly a month in the hospital. Some patients then go to stem cell transplant, which adds more time and recovery.

Induction / Intensification

The phases of chemotherapy treatment. Noah's protocol includes 5 phases: Induction 1, Induction 2, Intensification 1, Intensification 2, and Intensification 3. Each phase involves days of chemo followed by weeks of count recovery in the hospital.

Neutrophils

White blood cells that heal injuries and fight infection. They typically make up about 60% of white blood cells and are the primary component of the ANC.

Monocytes

Another type of white blood cell, typically composing 2-8% of white blood cells. Monocytes are included in the APC calculation along with neutrophils. A rise in monocytes after chemo can sometimes be a precursor to neutrophils starting to recover.

Platelets

Blood cells that help with clotting. Normal range is 150-450. Noah receives platelet transfusions when counts drop below 20. Platelets have a short lifespan (9-12 days) and are often the first to drop and last to recover after chemo, but they've recovered more quickly than hemoglobin for Noah. After rounds 2 and 3 his platelets shot up to the top of the normal range.

Remission

When MRD testing shows fewer than 5 abnormal cells per 10,000. This does not mean zero cancer cells or that treatment is over — it means the leukemia is "currently" under control. Noah achieved remission after induction 1 with just 1 abnormal cell per 10,000 detected. None were detected after induction 2.
