Surgical Resection is the Most Appropriate Management
Referral for surgical resection (Option D) is the definitive management for this patient with a 6 cm solitary hepatocellular carcinoma and preserved liver function, as it represents the only potentially curative treatment option for tumors of this size. 1
Primary Recommendation: Surgical Resection
The British Society of Gastroenterology strongly recommends surgical resection as first-line treatment for solitary HCC in cirrhotic liver of any size when liver function is maintained and adequate remnant liver volume can be preserved. 1 This recommendation applies directly to this clinical scenario with a 6 cm mass.
Surgical resection offers 5-year survival rates of 50-68% in experienced centers for a 6 cm solitary tumor, representing the only potentially curative option for tumors of this size. 1
Why Other Options Are Inappropriate
Chemotherapy (Option A) - Incorrect
- Traditional systemic chemotherapy has shown limited efficacy with only 10% response rate and no proven survival benefit, making it inappropriate for solitary HCC. 1
- Systemic therapy with atezolizumab plus bevacizumab or sorafenib is reserved for advanced, unresectable HCC, not for potentially resectable disease. 1
- The SHARP trial demonstrated sorafenib's role specifically in unresectable HCC, not as first-line treatment for resectable tumors. 2
Radiotherapy (Option B) - Incorrect
- Radiotherapy is not standard treatment for HCC and is not mentioned in current guidelines as a primary treatment modality for resectable disease. 1
Palliative Medicine (Option C) - Premature
- Palliative referral would be premature for a patient with potentially resectable disease and preserved liver function. 1
- This option should only be considered for Child-Pugh C patients or those with unresectable disease. 3
Critical Pre-Surgical Assessment Required
Before proceeding with resection, the surgical team must evaluate:
- Liver function parameters: Child-Pugh classification and presence/severity of portal hypertension must be assessed. 1
- Future liver remnant (FLR) volume: Minimum requirement is ≥40% for cirrhotic liver; portal vein embolization should be considered if FLR is inadequate. 1
- Tumor characteristics: Confirm absence of macroscopic vascular invasion and extrahepatic metastases, as these would contraindicate resection. 1
Post-Resection Management
- Adjuvant therapy with atezolizumab and bevacizumab may improve recurrence-free survival. 1
- Surveillance with liver imaging every 3-6 months for at least 2 years is essential, as recurrence rates reach 50-60% at 5 years. 1
Common Pitfalls to Avoid
The key pitfall would be selecting systemic chemotherapy or palliative care without first evaluating surgical candidacy, as this would deny the patient the only potentially curative treatment option. 1, 4, 5 Liver resection and transplantation remain cornerstone treatment options for patients with early-stage disease and constitute the only potentially curative options for HCC. 5
