Treatment of Solitary Early-Stage HCC (≤5 cm) When Surgical Therapy Is Not Performed

Clinical Scenario

This protocol applies to patients with a solitary hepatocellular carcinoma ≤5 cm who are ineligible for surgical therapy or who decline it. Even without surgery, curative-intent management remains the goal in this population.

Treatment Approach

Local ablative therapy with curative intent is the cornerstone of management. The specific modality is guided by tumor size and clinical factors — the full algorithm, including the criteria for each option, is detailed in the structured protocol.

Complete regimen, criteria, and sequencing available via the protocol link below.

Treatment Goal

Complete response with no viable residual tumor, confirmed on post-treatment contrast-enhanced imaging.

  1. Patients with solitary tumors ≤5 cm should be treated with curative intent using local ablative therapies if they are ineligible for or decline surgical therapy (Level 1, Strong Recommendation).
  2. Thermal ablation (radiofrequency or microwave ablation) should be considered the treatment of choice for patients with early-stage HCC ≤ 3 cm who are ineligible for or decline surgery (Level 1, Strong Recommendation).
  3. Targeted radioembolization (radiation segmentectomy) or EBRT may be used as alternative therapies to thermal ablation for patients with BCLC stage A HCC who are not candidates for surgical resection, including those with tumors >3 cm in size (Level 3, Strong Recommendation).
