Abstract: Objective This study was to summarize the clinical features of drug-induced liver injury (DILI) in patients with breast cancer during anthracycline chemotherapy. Methods A total of 155 patients with stage I/ IIbreast cancer after operation were encountered in our hospital between May 2020 and May 2023, and all received anthracycline chemotherapy. The clinicians maintained carefully surveillance on DILI, and the anti-tumor regimen was adjusted and the liver-protecting medicines were given in time according to the clinical types of DILI. Results During chemotherapy, the DILI was found in 92 cases (59.4%) out of our series, with the hepatocyte injury in 57 cases, the cholestasis in 25 cases and the mixed type in 10 cases; the age in patients with DILI was (45.6±7.2)yr, significantly older than [(40.5±8.5)yr, P<0.05], the body mass index was (26.2±2.2)kg/m², much greater than [(23.0±2.4)kg/m², P<0.05], and the incidences of concomitant hypertension, diabetes, hyperlipidemia and stage II tumor were 25.0%, 17.4%, 18.5% and 52.2%, all significantly higher than 6.3%, 4.8%, 4.8% and 31.7%, respectively(P<0.05)in patients without DILI; the chemotherapy was adjusted and the glycyrrhizic acid and/or ursodeoxycholic acid were given in patients with DILI, and the prognosis was promising. All patients went on chemotherapy thereafter. Conclusion The DILI occurs common in patients with breast cancer during anthracyclinechemotherapy period, and careful surveillance and appropriate management might obtain a good outcomes.
