However, these new treatments have specific class-related side effects. Pulmonary toxicity has been identified as an adverse event of special interest with everolimus, and is becoming an increasingly significant clinical challenge with the recent approval of trastuzumab deruxtecan. Overall, the risk of pulmonary toxicity is quite low but in some cases lung damage can be fatal. We conducted an update including the available published data regarding the incidence, mechanisms of pathogenesis, clinical presentations, and treatment of lung toxicity induced by new anticancer drugs. A literature search was performed between January and June 2024, considering papers, clinical trials, case reports, case series, meta-analyses, and systematic reviews published from January 2014 to June 2024. We also provide an algorithm for diagnosis and treatment, along with real-life cases managed at the Modena Cancer Center. Data provided here show that pulmonary toxicity is a quite frequent side effect and underline that early recognition and prompt treatment are crucial for the best outcome of patients, whose overall prognosis is being improved by the availability of these new anticancer agents.Keywords: breast cancer, lung toxicity, Pulmonary toxicity, interstitial lung disease, pneumonia, trastuzumab deruxtecan, CDK4/6i
