Human epidermal growth factor receptor-2 (HER-2) tyrosine kinase inhibitors (TKI) is the targeted drug of HER-2-positive breast cancer. Lapatinib, pyrotinib and neratinib, as ErbB family TKIs, have been approved by National Medical Products Administration and applied in the treatment of HER-2 positive breast cancer in China. The most common adverse effects (AEs) of TKI agents include diarrhea, drug-induced liver injury (DILI), nausea, vomiting, skin toxicity, cardiotoxicity and oral mucositis. The Breast Cancer Expert Group of Chinese Society of Clinical Oncology (CSCO) summarized the incidence and characteristics of AEs of TKI, evaluated the manifestations and severity of AEs, and formulated the consensus of the management of common AEs based on the clinical experiences and updated advances from domestic and abroad studies. This consensus aims to provide the practical strategy for clinicians in the management of ErbB-family TKI-related AEs in China, and eventually enhance the patients' compliance and improve the therapeutic efficacy.
人表皮生长因子受体2(HER-2)相关酪氨酸激酶抑制剂(TKI)是治疗HER-2阳性乳腺癌的靶向药物。拉帕替尼、吡咯替尼和奈拉替尼已在中国获批用于临床乳腺癌的治疗。TKI药物常见不良反应包括腹泻、药物性肝损伤、恶心、呕吐、皮肤毒性、心脏毒性和口腔黏膜炎等。中国临床肿瘤学会乳腺癌专委会专家组总结了TKI药物常见不良反应的发生率和特征，评估了不良反应发生的症状和分级，参考国内外研究进展并结合临床经验制定了相应的预防和治疗措施，旨在为临床医师提供切实可行的管理策略，推进国内乳腺癌TKI不良反应的管理，提高患者的依从性和治疗疗效。.
