Summary
Brief summary (as posted)
Patients who suffer from chronic myeloid leukemia are treated by tyrosin kinase inhibitors (TKI) saying imatinib, nilotinib, dasatinib, bosutinib and ponatinib. These drugs are highly efficient with excellent response allowing some patients to definitely stop their cancer treatment. However, in 30% of cases, when the treatment is stopped, pains could arise in shoulders, hips, joints… These symptoms occurring after the withdrawal of a drug are odd and biologically unexplained so far. This study seeks to discover the biological factors behind these symptoms called 'TKI withdrawal syndrome' by the scientific community.

- label
- Group with the TKI withdrawal syndrome
- description
- There is no intervention. Patients will stop their tyrosine kinase inhibitor yielding to 2 subsets: patients with or without the TKI withdrawal syndrome.
- label
- Group without the TKI withdrawal syndrome
- description
- As abovementioned.
Primary outcomes (11)
- measure
- Measurement of cytokines:
- timeFrame
- at diagnosis and every month during 3 months
- description
- Measurement of cytokines: A variation of 20% in a given marker will be significant if it is observed in the group with "TKI WS" but not in the group without "TKI WS". Of note, the patient will be his own witness. . In picogram/milliliter (pg/ml): IL2,IL 6, IL10, IL15, TGFβ,TNFα, IFNγ, VEGF, PDGFβ,
