Neutropenia, low haemoglobin (hemoglobine) and low platelets (trombocyten) are common with all CLL treatments, particularly neutropenia. Your specialist should be well aware of this. The standard approach with FCR treatment and often with other treatments where infusions are used, is to first delay the next infusion by say a week, then if the neutrophil count is still too low, to boost it with occasional G-CSF (such as filgrastim, perfilgrastim, neulasta, neupogen, Zarxio) injections as needed into the skin over the abdomen. The injections use a very fine, fairly short needle and aren't that uncomfortable. I've given myself many of them. Sometimes you can experience a bone pain side effect, in which case an antihistamine and perhaps APAP/Panadol/Tylenol (acetaminophen) usually helps.
Sometimes the neutropenia can worsen with each infusion, but it usually improves as the FCR clears the CLL out of your bone marrow.
I notice that you also have another common (lower immunity related) blood count symptom from your CLL, low IgA, IgG and IgM (hypogammaglobulinemia). They will continue to be low during your treatment and probably won't improve after you have finished FCR. If your IgG falls under typically 4.0 and you have some very serious infections, you might qualify for IVIG, but your IgG is unlikely to drop that far during treatment.
One other thing to keep in mind for the year after your last rituximab infusion - you are at a higher risk of what's called Late Onset Neutropenia occurring. Your neutrophil count can recover nicely after you finish treatment, only to plunge without warning into neutropenia once more. So take excellent care over the next 18 or more months to reduce your risk of infection. I've provided tips on how to live with neutropenia in a section on this topic towards the end of this post: healthunlocked.com/cllsuppo...
Many thousands of people have done well on FCR over the last 20 years or so. For about 55% of those who had IGHV mutated CLL, it was the only treatment that they needed. Some early trial FCR patients are now entering their third decade of remission. If you do need treatment again later, you should be able to access one of the newer, targeted therapies.
