Noah's Dad

Not much to report. Noah’s been home since January 2nd. It’s been a nice long break and we go back this Tuesday. We’re gearing up for round 4, which is by far the longest; we’ve heard 8 to 10 weeks.

First, a bit of recap on numbers since he’s been home. It’s a bit of a guessing game while he’s here since we’re not getting daily labs, but we did get them a couple times. On the 6th, we went back for the end-of-round bone marrow test and LP. The labs that day came out at hemoglobin of 10.2, platelets of 475, and ANC of 506.

A quick aside: You’ll notice that each of these indicators can now be hovered (click on mobile) for a summary. Only the first instance of each term in a given post gets highlighted to avoid clutter, but all display the summary when hovered. If you scroll to the bottom of the post, you’ll also see that any common terms in this post are listed; previous posts are also back-filled. You can also toggle to see the run-down on all common terms, which will be ever-evolving. For example, this exercise uncovered that I’ve been mistakenly referring to Noah’s central line as a port from time-to-time.

Those counts are about what we would have expected. The platelets again higher than the typical range and ANC just scratching above the severe neutropenia threshold. The more important thing was the MRD testing. We got that back later in the week and no abnormal cells were detected. Again, this does not mean there are not any, but none are detected. Yes, we probably predicted this, but we will never take any of these tests for granted.

On the 13th he went back in for a central line dressing change and got some updated labs. Hemoglobin was up to 10.6, platelets down to 380, and ANC up to 840. That puts platelets in a more normal range. On Tuesday, we’ll get labs prior to starting the round, so they will likely be at their highest point. It would be nice to see hemoglobin over 11 and ANC nearing 1,500 similar to the start of last round. These are, of course, going to tank during the round, but it helps to see the trend of recovery after.

I’ll plan to outline the round 4 treatment (Intensification 2) once we get into the thick of it next week. There will be a new chemo med which is a bit anxiety-inducing, but hopefully no surprises similar to the etoposide reaction last round.

Back here, Noah’s spirits and energy have been really good. He still gets tired easily during workouts, but rather than being visibly “done” after a workout, there’s energy still in the tank. We always play catch with a hacky-sack or tennis ball to end the workout. We both like playing catch anyway, but it also helps to keep hand-eye coordination maintained and to monitor for potential neurotoxic effects of chemo. Strength, balance, and coordination are all things that will be continually monitored. They seem to be pretty okay currently, but we’ve noticed some involuntary shaking/tremors from time to time since round 2, which is a common side effect.

Noah and Micah have had a blast hanging out. Once we got the labs with a little higher ANC we let them sleep in the same bed. They’ve probably both gotten to sleep later because of it, but trying to split them up does not go well, and it’s hard to beat all the joking and laughing. We also tried to all sleep in the same bed, but none of us slept real well that night. There continues to be much gaming. I bought two more controllers and even got Mayumi into this couch co-op game called Brotato. I don’t mind screens at all when we’re all playing together. We’ve also had one or two friends and family over for a few hours at a time. The kids also love Lego sets and the Home Alone set (thanks Tom and Carolyn West family!) pictured below is pretty incredible. We’re still very careful with masking of visitors, hand-washing, etc. during this flu season, but also trying to balance with some human interaction before he goes back.

That’s all for now. 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.

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.

Central Line

Two tubes surgically inserted into a large vein near the heart. Used for blood draws, IV fluids, transfusions, and chemo delivery. Makes treatment much easier than repeated needle sticks. The lines need to be flushed regularly with saline and heparin to prevent clotting.

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.

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.

Etoposide

A chemo drug used in phase 3. Noah had an allergic reaction to this one initially, which required pre-medication to avoid. It interferes with DNA copying, similar to one of daunorubicin's mechanisms but without the same heart toxicity concerns.

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.

Port

A port (or port-a-cath) is a device implanted entirely under the skin with a small reservoir that is accessed by a needle through the skin. Noah has a central line, not a port. A central line has external tubes, while a port is fully internal. Earlier posts mistakenly used "port" when referring to Noah's central line.

Thank you for the update. I'm thankful that I haven't had a reason to learn all the medical terms, etc, and I'm sorry that you're having to learn all that now. I'm keeping Noah and all of you in my prayers. Wish I could do something concrete.
