Summary
Preoperative transcatheter hepatic arterial embolization (PTHAE) effectively treats liver malignancies. This procedure converted unresectable tumors into resectable lesions, demonstrating significant necrosis and improved patient outcomes.
Area of Science:
- Hepatobiliary Surgery
- Interventional Radiology
- Surgical Oncology
Background:
- Liver malignancies pose significant treatment challenges.
- Surgical resection is a primary treatment modality for liver tumors.
- The role of neoadjuvant therapies in improving resectability is under investigation.
Purpose of the Study:
- To evaluate the efficacy of preoperative transcatheter hepatic arterial embolization (PTHAE) in liver malignancies.
- To assess the clinical and histopathological outcomes of PTHAE.
- To determine if PTHAE can convert unresectable liver tumors into resectable ones.
Main Methods:
- Retrospective analysis of ten patients with liver malignancies.
- Patients underwent PTHAE with lipiodol and chemotherapeutic agents.
- Histopathological examination of resected specimens was performed.
Main Results:
- Complete tumor necrosis was observed in 30% of patients.
- Extensive tumor necrosis (70%-95%) was seen in 70% of patients.
- Four initially unresectable tumors became resectable after PTHAE, with 60%-80% tumor burden reduction.
Conclusions:
- Preoperative PTHAE is a valuable procedure for managing liver malignancies.
- PTHAE can increase the rate of tumor resectability.
- The study suggests PTHAE is effective in converting unresectable liver tumors to potentially resectable lesions.
