Modified Laparoscopic Anatomic Hepatectomy: Two-Surgeon Technique Combined with the Simple Extracorporeal Pringle Maneuver

Laparoscopic anatomic hepatectomy (LAH) has become increasingly prevalent worldwide in recent years. However, LAH remains a challenging procedure due to ...

The pathogenesis of non-cirrhotic hepatocellular carcinoma (HCC) with a high recurrence remains controversial, while microvascular invasion (MVI) is highly suggestive of tumor recurrence. This study aimed to investigate the effects of liver fibrosis on MVI and prognosis in HCC.

The impact of liver fibrosis on microvascular invasion and prognosis of hepatocellular carcinoma with a solitary nodule: a Surveillance, Epidemiology, and End Results (SEER) database analysis.

 More and more studies have suggested that hepatocellular carcinoma (HCC) patients with high-risk recurrence factors can benefit the most from postoperative adjuvant transarterial chemoembolization (PA-TACE) for its potential effect in delaying cancer recurrence. However, it remains unclear if solitary HCC (SHCC) patients particularly those without high-risk recurrence factors should also receive PA-TACE. This study aimed to analyze the efficacy of PA-TACE in them.  Retrospectively, we enrolled 123 SHCC patients who either received radical hepatectomy alone (No TACE group, n = 39) or followed by PA-TACE (PA-TACE group, n = 84) in our institution. Prognostic risk factors, disease-free survival (DFS), and overall survival (OS) were analyzed using the Cox proportional hazard regression model, the Kaplan-Meier method, and the log-rank test.  Liver cirrhosis was the only independent risk factor for SHCC patients. Overall, the PA-TACE group had no improved OS ( = 0.977) but worse DFS compared with the No TACE group ( = 0.045). Consistently, in subgroup analysis, SHCC patients with negative microvascular invasion (MVI), tumor size ≤ 5 cm and preoperative alpha-fetoprotein (AFP) < 400 ng/ml had similar OS ( = 0.466,  = 0.864,  = 0.488, respectively) but even worse DFS ( = 0.035,  = 0.040,  = 0.019, respectively) than those in the No TACE group. Besides, there was no significant difference in DFS and OS between the two groups of SHCC patients with liver cirrhosis ( = 0.342,  = 0.941, respectively).  PA-TACE may not improve the long-term survival of SHCC patients, but may even potentially promote their postoperative tumor recurrence, especially for those with MVI-negative, tumor size ≤ 5 cm, and preoperative AFP < 400 ng/ml.
