Objective:To review the safety issues surrounding tyrosine kinase inhibitors (TKIs), specifically, hematological adverse effects, cardiovascular issues, renal adverse effects and nephrotoxicity, endocrine system adverse effects, concerns related to the reproductive system, dermatological and gastrointestinal adverse effects. Data Sources: A literature search was performed through Web of Science, PubMed, Google Scholar, Scopus, and the Food and Drug Administration. Data Summary: Several safety issues have been raised following the use of TKIs. Most TKIs show hematological side effects. Considering cardiovascular toxicities, as opposed to imatinib which is relatively safe, new-generation TKIs may be associated with severe cardiovascular side effects. Both acute and chronic renal failure were reported with TKIs such as gefitinib, imatinib, pazopanib, sorafenib, and sunitinib. Many endocrine adverse effects have been reported including hypercholesterolemia and hypertriglyceridemia (with lorlatinib) and thyroid dysfunction (with dasatinib). TKIs may interfere with fetus implantation, growth, and gonadal development. Females receiving TKIs and encountering unwanted pregnancy may have a normal pregnancy, miscarriage, or an abnormality in the fetus. Skin toxicity has been identified as the most debilitating adverse effect in patients receiving EGFR-TKI. Gastrointestinal side effects are common with TKIs. Diarrhea was the most frequently reported adverse effect of many TKIs. Conclusions: TKIs are increasingly taking up a critical role in the treatment of cancers due to their specific action toward malignant cells compared to conventional cytotoxic chemotherapy. Despite a dramatic improvement in the survival of patients with cancer following approval of TKIs, various early and late adverse effects were reported.
