LATE ONSET NEUTROPENIA MAY BE A COMPLICATION OF FCR

LATE ONSET NEUTROPENIA MAY BE A COMPLICATION OF FCR

Here's another EHA abstract on the under-recognized issue of late-onset neutropenia as a result of FCR. I thought that this might be interesting to those of us on this site that have undergone or may undergo FCR. See the graph above. Someone can correct me if I am wrong, but my guess is that the take-away is that if you had Grade 3-4 Neutropenia during FCR you should be watched for late-onset neutropenia also. Also, there is a warning about GCSF support during chemotherapy (Granulocyte colony-stimulating factor).

By the way, here are all the EHA abstracts from last week:

The paper:

LATE ONSET NEUTROPENIA IS A COMMON COMPLICATION OF FLUDARABINE, CYCLOPHOSPHAMIDE AND RITUXIMAB (FCR) THERAPY AND IS ASSOCIATED WITH SUBSTANTIAL MORBIDITY AND HOSPITALIZATION

The conclusions:

Summary/Conclusion: Neutropenic complications, particularly LON, is an under-recognized and poorly reported complication of FCR. LON in pts receiving FCR is associated with high morbidity and frequent hospitalization. Pts who develop G3-4N during FCR chemotherapy are at high risk of subsequent LON, particularly if their chemotherapy was supported using GCSF. Our results demonstrate that the onset of G3-4N during FCR chemotherapy identifies pts at high risk for late neutropenic complications, and sound a cautionary note regarding the use of GCSF support during FCR therapy.

  • I presume the Y scale is the probability of late onset neutropenia occurring? So after a year, about 20% of FCR treated patients that didn't have G3-4 neutropenia during treatment, have experienced late onset neutropenia, compared to more than double that if you did?

    And I was so hoping not to be living with neutropenia after treatment :(

  • Neil, you will be OK. By the time you need treatment, they will be using a combination therapy that will essentially get rid of our monoclonal B-cells and we will all live happily ever after. :-)
