Clinical Case Discussion Forum

Subscribe to the Clinical Case Discussion Forum

× To share and enhance best practice management of CML, experts and interested clinicians can discuss difficult or interesting CML cases here. Physicians submit a brief history of the patient and the case for discussion (no more than 200 words) by posting it in this forum ("New Discussion" button below). Please include the country of origin.

Each clinical case will be forwarded to the expert clinical panel for a brief independent response. Consideration should be given to patient confidentiality. Details that are not critical to the case can be changed to preserve anonymity. Please consider including your email with the case. This will not be posted on the website, but is useful should further details be requested by the moderator.

As a full clinical history is necessary for accurate comment, cases and comments on the Forum are ONLY ACCEPTED FROM PHYSICIANS. If individual patients have a specific question we encourage them to contact their healthcare provider. General questions can be emailed to info@cml-foundation.org.

Giving G-CSF in CML was created by Ehab Atallah

53 year old female diagnosed with CP-CML (WBC: 200,000 and Hb 8) and stage II breast cancer at same time.
Standard treatment: Dose dense Neoadjuvant AC/T followed by surgery followed by hormonal.

Given high count: Plan: Imatinib-->Surgery-->Dose dense ACT with G-CSF. Continue imatinib through all treatment. Consider switching to dasatinib after completion of therapy.

Thoughts?

The published experience is scarce. I like the plan: imatinib (ELTS RISK?) to complete and stable hematological response (when the risk of subsequent cytopenia is perceived to be reduced to ‘zero’’) followed by surgery > dose dense ACT.

Imatinib continued? Yes, in my past experience continuing imatinib during CHT was generally free of additional safety and clinical issues - I remember at least 3 cases similar to the present one.

Switching to Dasatinib at the end of treatment: I would consider this only if the response to and tolerability of imatinib are not optimal. Dasatinib is (considered) a strong immune-suppressant drug - acknowledged, more in vitro than proved in vivo - and knowing the relevance of immune response in breast cancer, an additional discussion point at the time of switching will be considered.

Hope this comment will contribute to finalize / improve the case discussion.

In this situation, I would personally wait to see how the patient tolerates the first cycle of chemotherapy before starting the TKI. I would consider initiating the TKI after recovery from the nadir of the first cycle.
