First Round of Carfilzomib and Cyclophosphamide Results

Even after all this time, I’m still not sure how to take the free light chains results.  I’m not a science-y person.  Dr. Rodriguez says that there’s been an improvement. This is the result from last week’s blood draw.

Component Your Value Standard Range
Free Kappa 3.19 mg/L 3.30 – 19.40 mg/L
Free Lambda 163.95 mg/L 5.71 – 26.30 mg/L
Kappa/Lambda Ratio 0.02 0.26 – 1.65

When I became aware that I had myeloma, the FLC test wasn’t used. We just looked at my m-spike(s) and quantitative immunoglobulins. It was a pretty simple way to see what was going on.  The FLC test is much more sensitive, so it’s a better diagnostic tool.

Results from July, 2019 for comparison.

The first cycle has been ok.  There’s a long list of possible side effects, but I haven’t experienced anything harsh. I have chronic gastritis, so that definitely affects how my stomach feels.  Were it not for that, I might get by with just the dex side effects.

For me, dex produces very predictable side effects. On the day I have it, I feel really speedy and I sweat profusely! I have trouble sleeping that night, so it’s not unusual for me to be awake until 3 AM.  Usually, I will sleep a few hours and be ok with that. The next day, I can be extremely grouchy. My face will be red.  The day after that, I feel exhausted.

It’s amazing that in the early days of my treatment, I would have to do what they called pulsed dex.  I would take 40 mg of it each day for 4 days, then have 4 days off.  Then I’d do it again. And again.  It was torture.

This week I have no treatment.  That’s how it’s scheduled.  Three weeks on and one week off. I’m happy to have this break.  I’ll let you know how the next cycle goes.

Carfilzomib and Cytoxan

Well, the daratumumab and pomalyst train has left the station without me.  My doctor decided that it wasn’t helping me anymore, so I’ve moved on.

A few weeks ago I started carfilzomib (Kyprolis) and cyclophosphamide (Cytoxan).  I also have 20 mg of dexamethasone every week. I have carfilzomib on Thursdays and Fridays and Cytoxan only on Thursdays.  I’ll have three weeks on, then one week off.  So far, my CBCs are pretty good.  I have only slightly low hgb, rbc and platelets.  Those were all low most of the time before this, anyway, so that’s nothing new.

As soon as I have some test results to post, I’ll do that.

If you’ve been on this treatment, I’d like to hear from you.
