Trastuzumab, a breast cancer drug, can cause liver injury. This case report details a patient experiencing elevated liver enzymes after completing trastuzumab therapy, highlighting a rare side effect.
Area of Science:
- Oncology
- Pharmacology
- Hepatology
Background:
- Trastuzumab is a targeted therapy for HER2-positive breast cancer.
- Hepatotoxicity is a rare but serious adverse effect of trastuzumab.
- Only two previous cases of trastuzumab-induced liver injury have been documented.
Observation:
- A 60-year-old woman received trastuzumab for stage I invasive ductal carcinoma.
- Following six months of treatment, routine tests revealed elevated liver transaminases.
- Extensive investigations excluded other causes of liver disease.
Findings:
- Trastuzumab was identified as the probable cause of the patient's liver injury.
- The timing of liver enzyme elevation correlated with trastuzumab administration.
- This case adds to the limited literature on trastuzumab-related hepatotoxicity.
Implications:
- Clinicians should monitor liver function in patients receiving trastuzumab.
- Early recognition of drug-induced liver injury is crucial for patient management.
- Further research may be warranted to understand the mechanisms of trastuzumab hepatotoxicity.
