Introduction Nilotinib is a second generation Tyrosine Kinase inhibitor (TKI) used in the treatment of Chronic Myeloid Leukemia (CML). The development of tyrosine kinase inhibitors has transformed chronic phase chronic myeloid leukemia from a disease with a poor prognosis to a treatable chronic disease. Long-term treatment with tyrosine kinase inhibitors means that patients must be clinically managed and monitored for years. While under Nilotinib tretament, the development of palmoplantar erythrodyesthesia is a very rare condition compared to other oncological drugs. Case report A 66-year-old male patient, who was diagnosed with chronic phase CML in 2019 had been placed under imatinib treatment . He had major molecular response loss in 2021, and was started on second generation TKI nilotinib 2  ×  400mg/day, considering his comorbidities. We present a case of a 66-year-old patient with CML who developed palmoplantar erythrodysesthesia on the 21st day starting nilotinib treatment. Conclusion It is important to manage the side effects that develop in long-term treatments. Adverse events can have a negative impact on patient compliance and quality of life and lead to poor clinical outcomes Our case is the first to develop PPE after beginning nilotinib use. We present this phenomenon to raise awareness and ignite a review of management strategies.In this case, we wanted to emphasize the importance of managing side effects.

Összefoglaló. A krónikus myeloid leukaemia ritka, klonális őssejt eredetű betegség. A myeloid sejtsor kóros működését a 9-es és 22-es kromoszómák reciprok transzlokációja következtében kialakuló fúziós gén (BCR/ABL1) által kódolt patológiás (fokozott) aktivitású tirozin-kináz jelátviteli fehérje okozza. A tartós, gyakran élethosszig tartó BCR/ABL1 specifikus tirozin-kináz-gátló (TKI-) kezelés a betegek jelentős hányadában az egészséges populáció túlélését elérő teljes gyógyulást biztosít, melyhez folyamatos, a mindenkori szakmai ajánlásoknak megfelelő onkohematológiai ellenőrzés szükséges. Az igen hatékony TKI-kezelés mellett azonban nemkívánatos mellékhatások jelentkezhetnek, melyek – számos szervrendszert érintve – a krónikus myeloid leukaemiás beteg kezelését multidiszciplináris együttműködéssé szélesítik ki. Jelenleg Magyarországon ötféle TKI érhető el, melyek mellékhatásprofilja igen eltérő. A kezelés elindításakor, illetve terápiamódosítás esetén beteg- és kórképspecifikus szempontokat mérlegelve kell kiválasztani az adott TKI-kezelést. Tekintettel a tartós kezelés mellett elérhető kiváló túlélési eredményekre, egyre gyakoribb azoknak a krónikus myeloid leukaemiás betegeknek a száma, akiknél változó súlyosságú nemkívánatos mellékhatások jelentkeznek, melyek miatt a betegek sokszor nem a hematológus szakorvosnál jelentkeznek. A leggyakrabban észlelt szövődmények ismertetését saját beteganyagunk részletes elemzése kapcsán a mindennapi klinikai gyakorlatban is bemutatjuk. Igen fontos, hogy a társszakmák (háziorvos, belgyógyász, kardiológus, angiológus, diabetológus, tüdőgyógyász, gasztroenterológus stb.) gyakorlói is tisztában legyenek az adott TKI-kezelés lehetséges mellékhatásaival, azok megelőzésével, időben történő felismerésével és hatékony kezelésével. Szakmai közreműködésük révén így segíthetik a klinikai hematológust a megfelelő terápia megtervezésében, valamint a betegek folyamatos kezelése kapcsán gyakran szükségessé váló szakmaspecifikus gondozásában is. Orv Hetil. 2021; 162(30): 1198–1207. Summary. Chronic myeloid leukemia is a rare clonal stem cell disorder. The pathological overproduction of the myeloid cell line is caused by abnormal function of a tyrosine kinase encoded by a fusion gene (BCR/ABL1) which is formed upon a reciprocal translocation of chromosomes 9 and 22. Long-term, often lifelong treatment with BCR/ABL1-specific tyrosine kinase inhibitors provides excellent disease control and overall survival rates close to the general survival of a healthy population in a significant proportion of patients. These patients require continuous oncohematological monitoring in accordance with the current diagnostic and treatment guidelines. However, undesirable side effects may occur that extend the treatment of the patients to a multidisciplinary approach involving a number of nonhematological specialities. Currently, five types of tyrosine kinase inhibitors are available in Hungary, with very different side effect profiles. At the start of treatment or in the event of a change in therapy, patient- and leukemia-specific assessments should be taken to select the most proper tyrosine kinase inhibitors treatment. Given the excellent survival outcomes achieved with long-term tyrosine kinase inhibitor treatment, there is an increasing number of patients who might experience adverse events of different kind or severity, which often results in patients ending up in different, nonhematological medical situations. The description of the most frequently observed complications in connection with a detailed cross-sectional analysis of our own patient cohort is also presented here resembling everyday clinical practice. It is very important that practitioners of other medical professions (general practitioner, internist, cardiologist, angiologist, diabetologist, pulmonologist, gastroenterologist, etc.) should be aware of the possible side effects of specific tyrosine kinase inhibitor therapies. They can help to assist the clinical hematologist in planning the appropriate tyrosine kinase inhibitor therapy as well as in professional caretaking of these patients.

Myeloid blast crisis of chronic myeloid leukemia (CML-MBC) is rarely seen at presentation and has a poor prognosis. There is no standard therapy for CML-MBC. It is often difficult to distinguish CML-MBC from acute myeloid leukemia expressing the Philadelphia chromosome (Ph+ AML). We present a case in which CML-MBC was seen at the initial presentation in a 75-year-old male. He was treated with conventional AML-directed chemotherapy followed by imatinib mesylate monotherapy, which failed to induce response. However, he achieved long-term complete molecular response after combination therapy involving dasatinib, a second-generation tyrosine kinase inhibitor, and conventional chemotherapy.

Abstract Abstract 2777 Background: The BCR/ABL transcript level at 3 months can predict long-term outcomes following frontline therapy with Imatinib or Dasatinib in chronic myeloid leukemia (CML) patients. However, data is lacking with second generation tyrosine kinase inhibitor (2GTKI) therapy after Imatinib failure. Methods: A total of 112 patients with CML in chronic phase (CP) receiving 2GTKI after Imatinib failure were reviewed. Treatment outcomes including complete cytogenetic (CCyR), major molecular (MMR) and molecular response 4.5 (MR4.5), treatment failure, progression-free (PFS) and overall survival (OS) were compared according to BCR/ABL transcript levels at 3 or 6 months, divided into <1%IS, 1–10%IS and °Ã10%IS. Results: Using cut off of 1%IS and 10%IS BCR/ABL transcript level, 70 patients (65%) showed <1%IS of BCR/ABL transcript level at 3 months, 16 patients (15%) between 1 and 10%IS, and 21 patients (20%), °Ã10%IS at 3 months. BCR/ABL transcript level at 3 months showed better correlation with OS (p<0.001) than that at 6 months (p=0.147). Better OS was also observed in the patients achieving <1%IS (100%) and 1–10%IS (100%) than those with °Ã10%IS at 3 months (70.6%, p<0.001). Those with <1%IS exhibited the best CCyR (100% at 12 months), MMR (93.1±3.2% at 18 months) and MR4.5 (80.2±6.3% at 3 years); those with 1–10%IS, intermediate (56.4±15.5% CCyR at 12 months; 22.1±14.1% MMR at 18 months; 10.0±9.5% MR4.5 at 3 years); and those with °Ã10%IS, the lowest CCyR (16.7±11.2% at 12 months), MMR (6.2±6.1% at 18 months) and MR4.5 rates (0%). Especially, in the subgroup of Imatinib resistant patients (n=59), none of them achieved MR4.5 if BCR/ABL transcript level is above 1% at 3 months (i.e. those with 1–10%IS or °Ã10%IS). Multivariate analysis confirmed strong correlation of BCR/ABL transcript level at 3 months with CCyR (HR 0.019), MMR (HR 0.047), MR4.5 (HR 0.057), treatment failure (HR 12.264), PFS (HR 7.754) and OS (HR 15.115). The group with <1%IS at 3 months maintained significantly lower BCR/ABL transcript level compared to other 2 groups. Conclusion: The BCR/ABL transcript level at 3 months is the most relevant surrogate for outcomes following 2GTKI therapy after Imatinib failure.
