When do abnormal free light chain numbers and borderline plasma cell percentages require treatment?
The decision to start treatment depends on several factors beyond just the free light chain ratio and plasma cell percentage. Not everyone with abnormal test results needs immediate treatment.
Some people without symptoms may not require treatment at the time of diagnosis. Your doctor will consider:
* Your overall symptom picture
* Kidney function trends (not just a single eGFR reading)
* Presence of organ damage
* Rate of disease progression
* Your age and overall health
Regarding kidney protection:
Light chain myeloma does carry a higher risk of kidney damage compared to other myeloma types. With an eGFR of 77, your kidney function appears relatively stable right now, but monitoring is crucial.
Your doctor will likely want to:
* Track your kidney function over time to see if it's declining
* Monitor your free light chain levels regularly
* Watch for any new symptoms or complications
The timing of treatment is highly individualized. Your oncologist will weigh whether starting treatment now offers more benefit than waiting and monitoring closely. This is definitely a conversation to have with your myeloma specialist, who can review all your test results together and discuss the best approach for your specific situation.
