A Rare Case of Primary Hepatic Undifferentiated Pleomorphic Sarcoma: Exploring Cancer-related Gene Mutations.
Hepatic undifferentiated pleomorphic sarcoma (UPS) is a rare malignant mesenchymal tumor with unclear cancer-related genetic mutations. In a 60-year-old Japanese woman with a rapidly growing, inoperable hepatic UPS, a genetic mutation analysis revealed KRAS and TP53 mutations. Despite initiating hepatic arterial infusion chemotherapy, the tumor continued to grow, and the patient's poor performance status complicated the transition to a phase I KRAS mutation drug trial, leading to death eight months after the symptom onset. A timely genetic mutation analysis may facilitate effective treatment transitions in hepatic UPS despite the lack of established treatments.
