Surgical Outcomes in Hepatocellular Carcinoma Management

Hepatocellular carcinoma (HCC) remains a leading cause of cancer mortality worldwide, and surgical intervention stands as the principal curative approach for early-stage disease. Advances in perioperative assessment, imaging and operative techniques have expanded indications for resection, even among patients with comorbid cirrhosis or portal hypertension. Contemporary series report 5-year overall survival rates approaching 60–70% in well-selected cohorts, reflecting improvements in patient selection, operative safety and postoperative care. Centralisation of liver surgery to high-volume centres and specialised surgeons has demonstrated reductions in mortality and major complication rates, while minimally invasive approaches have been shown to preserve functional reserve and hasten recovery. Outcomes remain closely tied to underlying liver function, tumour burden and the presence of portal hypertension or oesophagogastric varices, underscoring the importance of rigorous preoperative stratification. Global audits reveal variation in practice and highlight ‘failure to rescue’—the inability to prevent death after a major complication—as a key modifiable determinant of mortality, particularly in resource-limited settings. Emerging strategies focus on refining risk scores, optimising liver remnant function and integrating locoregional therapies with resection to improve long-term disease control.

Research from Nature Portfolio

Retrospective analyses have identified oesophagogastric varices as an independent negative prognostic factor in patients undergoing treatment for HCC, with significantly lower 5-year survival rates observed among those with variceal disease. This finding emphasises the need for endoscopic assessment and tailored perioperative management to mitigate bleeding risk and preserve liver function. A comparative study of surgical resection versus radiofrequency ablation in HCC patients with oesophagogastric varices demonstrated superior long-term survival following resection, particularly in younger patients with preserved hepatic reserve and unifocal tumours. These data support surgical resection as first-line therapy in carefully selected cases, provided that liver function is maintained and portal hypertension is controlled.

The graph below shows the total number of articles in surgical outcomes in hepatocellular carcinoma management across all publications each year (not limited to Nature Index journals).

Technical terms

Hepatocellular carcinoma (HCC): A primary malignancy of the liver arising from hepatocytes, often in the context of chronic liver disease.

Hepatic resection: Surgical removal of a portion of the liver containing tumour, aiming for clear margins while preserving adequate liver remnant.

Radiofrequency ablation (RFA): A minimally invasive technique that uses heat generated by radio waves to destroy tumour tissue.

Portal hypertension: Elevated blood pressure within the portal venous system, typically due to cirrhosis, increasing the risk of perioperative bleeding and liver decompensation.

Oesophagogastric varices (EGV): Dilated submucosal veins in the lower oesophagus or stomach, developing in response to portal hypertension and posing a risk of life-threatening haemorrhage.

Minimally invasive surgery: Surgical approaches such as laparoscopic or robotic techniques that use small incisions to reduce trauma, pain and recovery time.
