Abstract
Trastuzumab deruxtecan (T-DXd), a high-payload antibody drug conjugate, has been reported to exert potent antitumor effects and has recently shown promising efficacy against human epidermal growth factor receptor 2 (HER2)-positive adenocarcinoma. Despite its high efficacy, interstitial lung disease (ILD) is a severe adverse event (AE) associated with T-DXd. This report describes a patient who was successfully treated with a dose-reduced T-DXd challenge after recovery from ILD. Little disease progression was observed during the treatment interruption period; thus, the effect of T-DXd was considered to have been maintained. T-DXd may induce ILD, and re-administration under careful observation is considered an important option for treating patients with HER2-positive breast cancer.
期刊介绍:
This online-only journal publishes original case reports on all types of cancer. In particular, we welcome not only case reports of educational value in the diagnosis and treatment of cancers, but also reports on molecularly analyzed cancer cases, including gene mutations, gene fusions, gene expression, and changes in copy number, regardless of their known clinical significance. Assessing the molecular analysis of a tumor usually requires a “cancer conference” in which experts from various fields discuss it. Even if the authors and their respective “cancer conference” were unable to determine the clinical significance of molecular changes at the time of submission and publication, their data may provide evidence that will help the scientific community develop precision medicine solutions in the future. We welcome case reports with reviews of the literature on similar cases, as they are more useful and valuable to readers than are reports of rare cases. International Cancer Conference Journal is the official publication of the Japan Society of Clinical Oncology (JSCO).
