Noah's Dad

Glad to report that Noah completed Round 4 (Intensification 2) and has been back home since Tuesday. Given we’d heard all sorts of time estimates (7 to 10 weeks to much more), out in 36 days was relatively quick. As of now he’s scheduled to be back home for a couple weeks.

His counts are still really low, but it was a nice turnaround from the week before. The last post noted that he spiked a fever of 103 and was put on a couple heavy-hitter antibiotics. He still had a fever the night after that high of 103, but we haven’t seen one since. He started to feel better soon after and the cultures never detected a bacterial infection. We’re not quite sure what he had, but glad it passed quickly.

He had gotten a fever in the rounds prior to this too, but typically just above the 100.7 threshold, and was probably related to count recovery (when the immune system is starting to come back). This time the fever was much higher and he also had a few other minor symptoms like headache, cough, and nasal congestion.

At any rate, the clearest signs of count recovery did come the day after that last fever (last Monday) when his platelets rose instead of falling and some neutrophils were detected. We fully expected going into Monday night for him to get his fourth platelet transfusion of the round, but rather than dropping from 22 to under the transfusion threshold of 20 they went up to 27. Every day after that they continued to rise and were up to 180 by Tuesday, which is the most recent lab we have.

Hemoglobin held pretty well throughout the round with only one transfusion needed. The labs on Tuesday had him at 8.2. That’s still low, but it’s been holding there the past week, so hopefully it goes up from here.

The ANC is/was actually still quite low at 132. The trend was up the week leading up to Tuesday, but very slow recovery. This has been mentioned before, but early on the typical threshold we heard for discharge from the hospital was above 500 and below that is considered severely neutropenic. In reality, Noah’s been discharged just above 230 in a couple rounds and just above 300 in the other. This is quite a bit lower, but we’re also now used to looking at the numbers beyond just the ANC. For example, APC was at about 630 and the ANC typically closes the gap on that number. I’d like to think the doctor knows that we’re careful about infection control at home. Of course germs can be passed, but the same is true in the hospital. At a certain point, if the counts are going to recover anyway, that can happen at home or at the hospital.

That being said, we’ve got an appointment for a dressing change and labs next Monday and we’ll be curious to see where those counts are at. This is typically the longest round for a reason and it very well could follow that ANC recovery will continue slowly. It’s also not unheard of for a patient to be discharged and then have to get a transfusion in between rounds. I wouldn’t expect that for platelets, but it’s possible with hemoglobin. We continue to do workouts every day though and his energy does not seem markedly less, so hemoglobin is likely holding.

The ANC was also too low to perform the bone marrow test for the completion of this round. As such, they’re going to do that test on the first day back for round 5 (Intensification 3) and we won’t get the MRD test results until a few days later.

As previously mentioned, we watched a lot of the Winter Olympics and round 4 sort of fittingly ended at the same time. I’ll always correlate these Games with this round as it provided the round’s room “theme” and really helped pass the time. To me, the Olympics have always felt special and even more so in a time like this. In one sense, you could say — none of these silly games really matter as compared to dealing with cancer. But you can also look at them and say — this is the kind of thing that we live for: humans working their whole life to achieve mastery of their passion. Competition, team camaraderie…some positivity in this crazy world; it’s nice. Much too much curling though. More speed-skating, less curling, please. But I digress.

So he’s back home. We’re having a great time. The kids are loud — mostly Micah. He’s a pretty energetic kid anyway but, when Noah is home from the hospital, it’s a little like the movie “Step Brothers” here. Noah also had an organization donate what they call a “Little Wish”, which was a giant Avengers Lego set (see image below). 5,201 pieces should keep him (and Micah and Mayumi) busy for a while.

Uploading a few pictures also reminds me of how I look at hair loss during chemo a bit differently than I did before. I knew that chemo caused hair loss, but certainly not how and when. The “how” is pretty simple: most of the chemo drugs are indiscriminately attacking fast-replicating cells, and AML leukemia cells replicate extremely quickly. But you know what other cells replicate quickly? Yep, you got it: hair follicle cells. Just innocent bystanders caught in the mix. And then in terms of the “when”, I probably thought the hair loss was the heaviest when counts were the lowest, correlating hair loss with clinical significance. At least in the case of Noah’s AML treatments, there’s actually a delay though. Around day 15 of this round when Noah’s counts were as zero as can be, his hair and eyebrows had started to grow back. But now 20 or so days later, when his counts are coming up, the eyebrows and hair fully disappear. It was the same way last round.

Okay, that’s enough for tonight. 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.

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.

APC (Absolute Phagocyte Count)

A broader measure of immune cells that includes both neutrophils and monocytes. Doctors often want this above 300 before performing bone marrow tests. Calculated as: WBC × (% neutrophils + % bands + % monocytes) / 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.

Bone Marrow Test / Biopsy

A procedure to collect bone marrow samples (both liquid and solid) from the hip area. Used to check the percentage of leukemia cells remaining and for MRD testing. Noah is under anesthesia for this procedure.

Over and Out

During the first round of treatment, Noah and David got walkie-talkies to "super secret communicate" throughout the hospital. The first post after ended with "love you and over and out" and it stuck.

Neutropenia

A condition of low neutrophil concentration in the blood. An ANC below 1,500 is considered neutropenic, and below 500 is severely neutropenic with high infection risk. After chemo, Noah's ANC drops to zero and we wait for it to recover before going home.

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.

Hemoglobin

The oxygen-carrying protein in red blood cells. Normal range is about 11-16. Noah was admitted with a critically low hemoglobin of 4.7 and receives red blood cell transfusions when it drops to 7 or below.

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.

Thank you for being willing to share updates with us. All the while, also taking time to explain to us pertinent medical terms. You are all doing a tremendous job – each of you – Noah (of course!), David & Mayumi, and brother Micah. Your updates share with us how to "struggle well" in a tough experience. So I say thank you. We continue to pray for you as you endure this journey.

36 days in isolation definitely beats a possible 10 weeks! We were so pleasantly shocked to see Noah sitting with brother Micah the other evening on FaceTime. God is so good at sharing His blessings with His children. Enjoyed your little teaching lesson on hair, David. Helped me remember Luke 12:7 - “The very hairs of your head are all numbered.” Your glossary of terms is always so helpful and many bits of medical lingo are now starting to make sense in my feeble mind. Thank you for making the learning more comfortable as we journey along with you. Our prayers and those of 1,000’s of others continue for all four of you. Always we have hope and Romans 12:12 encourages us: “Be joyful in hope, patient in affliction, faithful in prayer.” Love to you 4 from us 2 - Mom/Dad
