Aumolertinib has been shown to bea safe agent in the registry study. However, successful rechallenge with aumolertinib following osimertinibinduced myocardial damage has not been reported.  \nIn this article, a case of neoadjuvant therapy for lung adenocarcinoma is retrospectively analyzed, and the relevant literature is reviewed. The patient was diagnosed with stage IIIA lung adenocarcinoma, and genetic testing revealed EGFR exon 19 deletion mutation combined with Tumor Protein p53 (TP53) mutation. The mutation abundance is 33.5 and 14%, respectively. One month after osimertinib treatment, the patient developed myocardial damage, and abnormal indicators such as myocardial enzyme spectrum showed abnormalities and cardiac insufficiency, followed by pulmonary hypertension and pulmonary edema. Aumolertinib was subsequently used for treatment, following which the myocardial enzyme spectrum returned to normal, and the symptoms of bilateral interstitial edema disappeared. In addition to the disappearance of adverse reactions, the therapeutic  \neffect was excellent; the lung lesions and mediastinal lymph nodes were significantly reduced, and the operation was successfully conducted. This is the first report of successful neoadjuvant treatment of EGFR exon 19 deletion combined with TP53 mutation in NSCLC using aumolertinib after osimertinib-induced myocardial damage. The results suggested that aumolertinib had fewer adverse reactions in patients with EGFR exon 19 deletion combined with TP53 mutation, and aumolertinib may be a potential neoadjuvant therapy for stage IIIA lung cancer.

GLOBOCAN estimates that in 2020, there will be approximately 2.2 million new cases of lung cancer worldwide, accounting for 11.4% of all malignancies, and approximately 1.8 million deaths, accounting for 18.0% of malignant tumor-related deaths [1]. Nonsmall cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for approximately 85% of all lung cancers, with a 5-year survival rate of less than 15% [2,3]. Patients with advanced NSCLC with epidermal growth factor receptor (EGFR) mutation form a special group, which is sensitive to tyrosine kinase inhibitors (TKIs) of EGFR and shows significantly improved  \nThis is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBYNC-ND), where it is permissible to download and share the work provided it is properly cited.
