Subsegmentectomy is a safe surgical option for small hepatocellular carcinoma in patients with cirrhosis, offering a 51% 5-year survival rate. This anatomical resection technique is recommended for early-stage liver cancer.

Area of Science:

  • Hepatobiliary surgery
  • Surgical oncology
  • Hepatocellular carcinoma research

Context:

  • Hepatocellular carcinoma (HCC) often complicates cirrhosis, posing surgical challenges.
  • Advancements in intraoperative ultrasonography and vascular occlusion enable precise anatomical resections.
  • Systematic subsegmentectomy has emerged as a viable surgical approach for HCC.

Purpose:

  • To evaluate the safety and long-term outcomes of systematic subsegmentectomy for hepatocellular carcinoma.
  • To assess the efficacy of subsegmentectomy in patients with cirrhosis and chronic hepatitis.

Summary:

  • A clinical study of 163 patients demonstrated subsegmentectomy to be a safe procedure with a low operative mortality rate (0.6%).
  • The 5-year survival rate following subsegmentectomy was 51%, indicating favorable long-term results.

  • Microscopic cancer spread, including portal venous invasion (41%) and intrahepatic metastasis (31%), was frequently observed in resected specimens.

    • Impact:

    • Subsegmentectomy is established as a primary surgical choice for early-stage hepatocellular carcinoma in patients with chronic liver disease.
    • This technique improves patient outcomes by enabling curative resection in complex cases.
    • Findings support the oncological rationale for subsegmentectomy in managing small HCC with cirrhosis.
