Abstract:
The development of targeted therapy drugs acting on tumor growth and progression is greatly expanding these last years. Among them kinase inhibitors have a prominent position and have demonstrated efficacy and clinical benefits in solid and hematologic malignancies. Compared to conventional systemic cytotoxic chemotherapeutic agents, their specific mechanism of action limits the occurrence of adverse events. However, as targeted kinases are shared by normal cells, their inhibition can affect physiological cell function. In this review we will focus on the side effects of kinase inhibitors on blood platelets which actively use kinase-related signalling pathways to prevent haemorrhages following vessel injury. Major functions of platelets are to adhere to the subendothelial matrix and to aggregate to form a haemostatic plug preventing excessive blood loss upon vascular lesion. Several kinase inhibitors including dasatinib and ibrutinib have been reported to affect specific steps of platelet activation process and to increase bleeding risk. This has important clinical implications particularly in patients treated with antithrombotic drugs. We will describe the effect of kinase inhibitors known to affect platelet activation and discuss the potential impact of those under development that may also interfere with platelet functions.
Insights
Kinase inhibitors, used in cancer therapy, can impact blood platelet function, increasing bleeding risk. This review examines these side effects and their clinical implications, especially for patients on antithrombotic drugs.
Area of Science:
- Oncology
- Hematology
- Pharmacology
Background:
- Targeted therapy, particularly kinase inhibitors, is a rapidly advancing field in cancer treatment.
- These drugs offer efficacy in various malignancies with fewer side effects than traditional chemotherapy.
- However, kinase inhibitors can affect normal physiological functions due to shared kinase targets.
Purpose of the Study:
- To review the side effects of kinase inhibitors on blood platelet function.
- To discuss the impact on hemostasis and bleeding risk.
- To explore implications for patients on antithrombotic medications.
Main Methods:
- Literature review focusing on kinase inhibitors and their effects on platelet activation.
- Analysis of reported clinical data and preclinical studies.
- Discussion of known and emerging kinase inhibitors impacting platelet function.
Main Results:
- Several kinase inhibitors, such as dasatinib and ibrutinib, are known to impair platelet activation.
- These effects can lead to an increased risk of bleeding.
- The clinical significance is heightened in patients concurrently using antithrombotic agents.
Conclusions:
- Kinase inhibitors can interfere with critical platelet functions, including adhesion and aggregation.
- Understanding these side effects is crucial for managing patient safety and optimizing treatment strategies.
- Further research is needed for kinase inhibitors in development that may also affect platelet hemostatic functions.
