Detecting small additional hepatocellular carcinomas (HCCs) is vital for surgeons. Many patients (27%) have multiple HCCs, impacting survival, especially those with cirrhosis, necessitating improved detection and follow-up.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Oncology
  • Hepatology

Background:

  • Small hepatocellular carcinomas (HCCs) often go undetected before surgery.
  • The presence of multiple HCC nodules impacts patient prognosis.
  • Accurate detection of additional HCCs is critical for surgical planning and patient outcomes.

Purpose of the Study:

  • To assess the incidence and characteristics of pathologically diagnosed multiple HCCs.
  • To evaluate the impact of additional HCC nodules on patient survival.
  • To identify factors influencing the detection of additional HCC nodules.

Main Methods:

  • Retrospective analysis of 267 patients undergoing hepatic resection for HCC.
  • Pathological examination to identify and characterize additional HCC nodules.

  • Statistical analysis to compare outcomes between single and multiple HCC groups, and to assess factors like cirrhosis and nodule detection timing.

    • Main Results:

    • 27% of patients had 95 additional HCC nodules detected.
    • Patients with multiple HCCs had significantly worse survival rates (p = 0.0013).
    • Additional nodules were detected before surgery (22%), during surgery (31%), and post-surgery (47%), with smaller mean diameters detected later.
    • Cirrhosis increased the odds of detecting new HCC nodules during or after surgery (OR = 5.444, p = 0.0087).

    Conclusions:

    • Improved preoperative and intraoperative detection of small HCC nodules is crucial, particularly for patients with cirrhosis.
    • Meticulous postoperative follow-up is essential for patients with cirrhosis to detect new HCC nodules.
    • For patients without cirrhosis, surgical decisions can rely on preoperative imaging.
