Abstract
Almonertinib, a representative epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), is the first-line standard treatment for EGFR-mutant advanced non-small-cell lung cancer; however, it may induce drug-related interstitial lung disease (ILD). This case report presents a 67-year-old female with advanced lung adenocarcinoma, who was diagnosed with an EGFR exon 19 deletion mutation. After 2 months of first-line almonertinib treatment (110 mg/day), a PR was achieved; however, progressive respiratory distress emerged. Chest computed tomography revealed ground-glass opacities accompanied by grid-like changes in both lungs, leading to a diagnosis of EGFR-TKI-related ILD (grade 2). Following glucocorticoid treatment and medication discontinuation, the lung lesions improved. Given the persistent tumor activity, the patient was switched to firmonertinib (80 mg/day) for targeted therapy. This switch did not lead to a recurrence of ILD symptoms, with a progression-free survival exceeding 5 months and good tolerability. This suggests that for patients with ILD associated with almonertinib and firmonertinib may serve as an effective and safe alternative. Closely monitoring ILD in clinical practice and promptly switching to similar drugs may avoid chemotherapy intervention and optimize treatment strategies. This case marks the first report of clinical experience achieving sustained remission by switching to a similar drug, firmonertinib, in patients with ILD related to almonertinib.
期刊介绍:
Anti-Cancer Drugs reports both clinical and experimental results related to anti-cancer drugs, and welcomes contributions on anti-cancer drug design, drug delivery, pharmacology, hormonal and biological modalities and chemotherapy evaluation. An internationally refereed journal devoted to the fast publication of innovative investigations on therapeutic agents against cancer, Anti-Cancer Drugs aims to stimulate and report research on both toxic and non-toxic anti-cancer agents. Consequently, the scope on the journal will cover both conventional cytotoxic chemotherapy and hormonal or biological response modalities such as interleukins and immunotherapy. Submitted articles undergo a preliminary review by the editor. Some articles may be returned to authors without further consideration. Those being considered for publication will undergo further assessment and peer-review by the editors and those invited to do so from a reviewer pool.
