We performed a systematic review and meta-analysis to fully investigate the thrombocytopenia of Platelet-derived Growth Factor Receptor Kinase Inhibitors (PDGFR-TKIs) in cancer patients. Databases were searched for randomized controlled trials (RCTs) treated with PDGFR-TKIs till January 2021. The relevant RCTs in cancer patients treated with PDGFR-TKIs were retrieved and the systematic evaluation was conducted. Nineteen RCTs and 3962 patients were included. Our study suggests that PDGFR-TKIs significantly increased the risks of all-grade (RR, 5.72; 95%CI, 4.32-7.59;p<0.00001; I(2) = 32%) and high-grade (RR, 5.65; 95%CI, 3.28- 9.75; p<0.00001; I(2) = 0%) thrombocytopenia in cancer patients. Sunitinib tend to be associated with the highest risk of thrombocytopenia among the included PDGFR-TKIs. The RR of high-grade thrombocytopenia varies significantly according to treatment line and median age. The available data suggested that the use of PDGFR-TKIs were associated with a significantly increased risk of thrombocytopenia. This article is protected by copyright. All rights reserved.
