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.

Palmoplantar Erythrodysesthesia

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.

Target Effect

Dasatinib is the second-generation tyrosine kinase inhibitor used in the treatment of chronic myeloid leukemia. Proteinuria has been reported with this agent. We describe two kidney biopsy–proven cases of dasatinib-induced thrombotic microangiopathy that responded to stoppage of dasatinib and using an alternate tyrosine kinase inhibitor. Certain specific tyrosine kinase inhibitors lead to endothelial injury and renal-limited thrombotic microangiopathy. Hematologists and nephrologists need to be familiar with this off-target effect of dasatinib.

Összefoglaló. Bevezetés: A krónikus myeloid leukaemia a diagnosztika fejlődésének és a tirozin-kináz-gátlók bevezetésének köszönhetően az elmúlt évtizedekben kiváló prognózisú betegséggé vált. Célkitűzés: A betegséggel kapcsolatos ismereteink nagy része klinikai vizsgálatokból származik, emiatt kiemelt szerepük van a nem szelektált beteganyagon végzett elemzéseknek. Módszer: Retrospektív elemzésünkben a Semmelweis Egyetem Belgyógyászati és Onkológiai Klinikáján 2003 és 2019 között tirozin-kináz-gátló kezelésben részesült betegek adatait tekintettük át. Eredmények: Klinikánkon összesen 88 beteg részesült terápiában, közülük 73 beteg az analízis időpontjában is kezelés alatt állt. A betegek 5 éves össztúlélése 86%, 5 éves progressziómentes túlélése 70% volt. 9 beteg halt meg, közülük 2 betegnél a halál oka a progrediáló alapbetegség volt. 38 betegnél volt szükség az első vonalban terápiaváltásra, a váltás oka akkor elsősorban az elégtelen terápiás válasz volt. A későbbi terápiaváltásokra elsősorban intolerancia miatt került sor. Az első vonalban a betegek több mint fele major molekuláris választ ért el, a jelenlegi kezelés mellett a betegek 85%-ánál major molekuláris választ detektáltunk. Megbeszélés: Adataink alapján az intézményünkben kezelt betegek túlélése és a betegek által elért terápiás válasz megfelel a nemzetközi adatoknak. Következtetés: Mivel nem válogatott beteganyagról van szó, a kapott eredmények pontosabb képet adhatnak a krónikus myeloid leukaemia tirozin-kináz-gátlóval történt kezelésének eredményeiről. Orv Hetil. 2021; 162(32): 1297–1302. Summary. Introduction: As a result of advances in diagnostic techniques and the introduction of tyrosine kinase inhibitors, the prognosis of chronic myeloid leukemia has improved over the last decades. Objective: Most of our knowledge about chronic myeloid leukemia results from clinical trials, therefore data derived from non-selected patient population is substantial. Method: Data of chronic myeloid leukemia patients treated with tyrosine kinase inhibitors at the Department of Internal Medicine and Oncology, Semmelweis University, between 2003 and 2019 were analysed retrospectively. Results: 88 patients received treatment, 73 patients were on therapy at the time of the analysis. Overall survival at 5 years was 86%, progression-free survival at 5 years was 70%. 9 patients died, 2 of them due to progressive disease. 38 patients needed 2nd line therapy, the main reason of treatment change was failure of therapy. Subsequent treatment modifications were conducted mostly because of intolerance. More than half of the patients on 1st line treatment reached major molecular response and 85% of the patients on treatment at the end of the analysis are in major molecular response. Discussion: Based on our data, survival and therapeutic response of patients in our center are similar to the international results. Conclusion: This analysis provides real-world data about treatment results of chronic myeloid leukemia in the tyrosine kinase inhibitor era. Orv Hetil. 2021; 162(32): 1297–1302.

Potential Interactions

Rationale Tyrosine kinase inhibitors are increasingly used in the treatment of cancer. Drug interactions involving tyrosine kinase inhibitors are commonly encountered in clinical practice. The objective of this study was to describe the frequency of tyrosine kinase inhibitor-associated drug interactions among a cohort of oncology patients. Methods Adult patients were included who presented to either of two outpatient oncology practices and were prescribed a tyrosine kinase inhibitor during 2 January 2013 to 1 January 2015. Demographic and medication data were abstracted from electronic medical records. Lexicomp®, Micromedex Solutions®, and medication labeling were utilized to identify potential interactions between tyrosine kinase inhibitors and concomitant medications. Interactions were then assessed by the investigators for clinical significance. The primary outcome was the frequency of significant drug interactions involving tyrosine kinase inhibitors and concomitant medications. Secondary outcomes included describing the nature and clinical impact of interactions, and describing interactions by medication class. Results A total of 356 patients were identified for analysis, in whom 244 potential interactions were identified, and 109 (44.7%) of which were considered severe. Decreased tyrosine kinase inhibitor absorption due to acid suppressive therapy and CYP3A4 interactions were the most frequent mechanisms of potential subtherapeutic and supratherapeutic concentrations, respectively. Potential clinical consequences included QTc prolongation ( n = 53, 48.6%), decreased tyrosine kinase inhibitor concentration ( n = 53, 48.6%), and increased tyrosine kinase inhibitor concentration ( n = 3, 2.8%). Conclusions Safer alternative therapy and/or more frequent clinical monitoring should be considered if an interaction poses a significant risk of increased tyrosine kinase inhibitor toxicity or decreased tyrosine kinase inhibitor efficacy. Oncology pharmacists can play a role in screening for tyrosine kinase inhibitor-associated interactions, recommending alternative therapies or dosing strategies, and monitoring tyrosine kinase inhibitor efficacy and toxicity.

Abstract The paradigm for managing patients with chronic myeloid leukemia is evolving. In the recent past, restoring a normal life expectancy while patients are receiving never-ending targeted therapy with BCR–ABL1 tyrosine kinase inhibitors through prevention of progression to blast phase and mitigation of iatrogenic risks was considered the best achievable outcome. Now, long-term treatment-free remission with continued response off tyrosine kinase inhibitor therapy is recognized as the most optimal benefit of treatment. Indeed, numerous independent clinical trials provided solid proof that tyrosine kinase inhibitor discontinuation was feasible in patients with deep and sustained molecular responses. This article discusses when tyrosine kinase inhibitors may be safely stopped in clinical practice on the basis of the best and latest available evidence.
