May 16th Update

Hi everyone,

Rob has been dealing with severe  hip pain. Thankfully,  he has been able to get some  walking back in after not being able to due to the pain. We are hopeful and hoping it is nerve/muscular related vs bone pain caused by multiple myeloma.

His rib pain where the plasmacytoma is has subsided greatly after the radiation! We’ll get this hip pain under control, and he’ll be back to making even more strides again soon. 👊👊👊

Lambda and Kappa Light Chains

I wanted to elaborate on  lab results a bit, but didn’t want to include too much in the last post. I’m trying to break up the information so it’s easier to digest.

In multiple myeloma, there is what is known as Kappa light chain myeloma and Lambda light chain myeloma.

Rob has Lambda light chain myeloma. As such, we look for the Lambda light chain results on his myeloma labs to see how the multiple myeloma is responding to treatment. 

The past 2 months, while the Lambda light chains have been normal, his tests identified a Kappa protein.

At Rob’s last appointment, we learned that this treatment he is on can cause a Kappa protein to be identified. If this is the cause, it usually stays small and quiet.

They said there is a specific lab test they will do to see if the Kappa protein showing up on the past 2 labs is simply caused by the new treatment, verses caused by the multiple myeloma.

If it is not caused from the new treatment, we’ll discuss what this means with his hematologist oncologist. This  Kappa protein is new to us, and we are appreciative of all we are learning from everyone at LCI.

Depending on that result, plus upcoming labs, will help determine next step as far as bone marrow biopsy. For example, if the Kappa light chain is found to be caused by the medication, and his lambda chains remain normal, then we will proceed with a bone marrow biopsy.

The purpose of the bone marrow biopsy is to see how many multiple myeloma cells are still present.  More on the bone marrow biopsy and the significance of this test in a future post.

Up Next: 

Rob continues oral chemo at home, and is back at LCI next week for treatment. The next  labs are in 2 weeks.

Thanks for being here!!🥰❤️
