× To share and enhance best practice management of CML, experts and interested clinicians can discuss difficult or interesting CML cases here. Clinicians submit a brief history of the patient and the case for discussion (no more than 200 words) by posting it in this forum ("+ NEW TOPIC" 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 CLINICIANS. 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.

We do not know if this blast crisis is lymphoid or myeloid. To know this as well as to search for mutations is essential to know which chemo and which TKI has to be used in combination (certainly not imatinib). If the mutation analysis cannot be performed Ponatinib 45mg a day is the best solution, to be associated with dexamethasone (at a dose of 20 mg per day)-If there is a persistent MRD positivity (measurable) I would consider Blinatumomab to reach at least MR4 or MR4.5, but allo SCT is always needed. If the BC is myeloid I would associated the ponatinib or at least dasatinib to the AML chemocycle that you use in AML. The goal in anycase is to reach a good remission (at least MMR, but deeper is always better) and then to move the patient to an allo transplant. More details are needed. and if you want you can write me directly.

If you do not have facilities to perform this kind of therapies, as Mauritius according to my knowledge is an extra European territory of France, the best option is to move the patient to France.
