{Abstract}: <B>BACKGROUND: </B>This study aimed to compare the effectiveness of liver resection (LR) and microwave ablation (MWA) in hepatocellular carcinoma (HCC) patients with early recurrence and varying stages of cirrhosis.<BR><B>METHODS: </B>This study analyzed patients with HCC who underwent hepatectomy and experienced early tumor recurrence (≤3 cm) between December 2002 and December 2020 at the Tongji Hospital. Treatment effectiveness was assessed using a propensity score matching (PSM) analysis.<BR><B>RESULTS: </B>This study included 295 patients (106, LR; 189, MWA), 86 patients in each of the 2 groups were chosen for further comparison, after PSM. After PSM, both LR and MWA demonstrated similar recurrence-free survival (RFS) and overall survival (OS) rates (p = 0.060 and p = 0.118, respectively). However, the LR group had more treatment-related complications. In patients with moderate or severe cirrhosis, no significant differences in RFS or OS rates were found between the LR and MWA groups (p = 0.779 and p = 0.772, respectively). In patients without cirrhosis or with mild cirrhosis, LR showed better RFS and OS rates than MWA (p = 0.024 and p = 0.047, respectively). Multivariate analysis after PSM identified moderate or severe cirrhosis and recurrence intervals ≤12 months as independent predictors of poor RFS and OS in patients with early recurrence of HCC.<BR><B>CONCLUSIONS: </B>LR is more effective than MWA for early recurrence of HCC in patients without cirrhosis or with mild cirrhosis, showing improved RFS and OS rates. In patients with moderate or severe cirrhosis, the OS and RFS were statistically equal between the two therapies. However, MWA may be preferred owing to its low complication rate.
