Background: Mitogen-activated protein kinase (MEK) inhibitors, which integrate the important signaling chain of the RAS-RAF-MEK-ERK1/2 pathway, regulate cell functions such as division and proliferation for patients with solid tumors. However, various ocular adverse effects (AEs) affect patients during clinical treatment. This systematic review aimed to assess the occurrence of AEs during treatment with MEK inhibitors plus targeted therapy or chemotherapy. Methods: A scientific literature search was conducted in PubMed, the Cochrane Library, Embase, and several Chinese databases to identify randomized controlled trials. Overall, ocular AEs were assessed as the primary end point; blurred vision, chorioretinopathy, and retinal detachment were assessed as secondary end points. Results: Seventeen randomized controlled trials were included. Overall, the use of MEK inhibitors combined with other targeted inhibitors or chemotherapy was significantly associated with a nearly 7.3% increased risk of overall ocular toxicities vs therapy without MEK inhibitors (risk ratio [RR], 2.88; 95% CI, 1.42-5.85, P < .05). An increased risk of blurred vision (RR, 4.10; 95% CI, 2.55-6.58; P < .05), chorioretinopathy (RR, 8.36; 95% CI, 3.42-20.47; P < .05), and retinal detachment (RR, 8.98; 95% CI, 3.92-20.57; P < .05) was demonstrated. Conclusions: Treatment with MEK inhibitors combined with targeted drugs or chemotherapy seems to increase overall ocular AEs. A more practical algorithm for the screening of ocular AEs was suggested to be conducted whenever new or worsening ocular toxicities occur., MEK proteins are mitogen-activated protein kinase, an important downstream part of the RAS-mitogen-activated protein kinase (MAPK), also known as the RAS-RAF-MEK-ERK1/2 pathway, highly regulating and playing an important role in [...]
