Combination therapy with paclitaxel and trastuzumab for human epidermal growth factor receptor 2‐positive recurrent serous carcinoma of the uterine cervix: A case report

Abstract

AbstractRecent studies show increased expression of human epidermal growth factor receptor 2 (HER2) in cervical cancer, but the efficacy of anti‐HER2 therapy remains under‐researched. Here, we present a case of recurrent HER2‐positive serous carcinoma, presumably arising in the cervix, diagnosed by comprehensive genomic profiling, which responded to trastuzumab. The patient underwent a radical hysterectomy with concurrent adjuvant chemoradiotherapy. One year after surgery, the patient experienced recurrence (multiple lymph node metastases). She underwent chemotherapy and subsequent comprehensive genomic profiling, which revealed HER2 positivity. Despite treatment, the lymph node and peritoneal metastases progressed. Therefore, combination chemotherapy with paclitaxel and trastuzumab was initiated. Subsequently, the patient's clinical symptoms improved considerably, and good health was maintained for 8 months. This report highlights the importance of comprehensive genomic profiling and targeted therapies when standard treatments fail.
