Experiences with surgically treated primary or secondary hepatic sarcoma

Area of Science:

• Hepatobiliary Surgery
• Surgical Oncology
• Gastroenterology

Background:

• Liver resections for hepatic sarcoma are infrequent, with limited alternative treatments.
• Surgery provides the sole aggressive option for achieving a tumor-free status in patients with hepatic sarcoma.

Purpose of the Study:

• To evaluate the outcomes and survival rates of patients undergoing liver resection for hepatic sarcoma at a specialized hepato-biliary university hospital.

Main Methods:

• A retrospective analysis of 11 liver resections performed for primary or metastatic hepatic sarcoma between January 2004 and July 2013.
• Data collected included demographic and clinical parameters, surgical procedures, resection margins, tumor size, postoperative morbidity, and survival rates.

Main Results:

• Liver resection was performed in 1.2% of 896 anatomical liver resections, primarily for metastases (83%).
• Tumor-free resection margins were achieved in 82% of patients. Postoperative morbidity was low (Clavien-Dindo score 2), with one perioperative death.
• 1-, 2-, and 3-year survival rates were 91%, 63%, and 45%, respectively, with a 63% tumor recurrence rate.

Conclusions:

• Liver resection for hepatic sarcoma is a rare but necessary intervention when aiming for complete tumor removal.
• While achieving tumor-free margins is feasible, high recurrence rates significantly impact long-term survival.
• Further research into optimizing adjuvant therapies is warranted to improve outcomes for these patients.
