Background:
Hepatocellular carcinoma (HCC) larger than 10 cm has a poor prognosis, with high recurrence rates, particularly distant metastases. This study examined whether lenvatinib treatment followed by liver resection improves the outcomes for large HCCs compared with upfront surgery.
Methods:
We retrospectively analyzed 30 patients with HCC larger than 10 cm who underwent hepatectomy at our institution between January 2008 and December 2023. The study cohort included 30 patients: 9 received preoperative lenvatinib treatment followed by hepatectomy (LEN group), while 21 patients underwent upfront surgery (UFS group). We compared the clinicopathological characteristics, surgical outcomes, recurrence patterns, and survival between the two groups.
Results:
The median duration of lenvatinib administration was 1.8 months, with partial response in two patients (22.2%) and stable disease in seven patients (77.7%). While lenvatinib treatment significantly decreased serum albumin levels (p < 0.05) and increased ALBI scores (p = 0.03), the surgical outcomes including blood loss, operation time, and complication rates were comparable between the two groups. The 3-year recurrence-free survival rate was significantly higher in the LEN group compared with the UFS group (66.7% vs. 16.1%, p = 0.027). The 3-year overall survival rate was also higher in the LEN group, though not statistically significant (85.7% vs. 56.1%, p = 0.059). Notably, distant metastasis rates were lower in the LEN group compared with the UFS group (11.1% vs. 47.6%, p = 0.10).
Conclusions:
Preoperative lenvatinib treatment followed by hepatectomy for large HCC (> 10 cm) may reduce recurrence, particularly distant metastases, and potentially improve long-term survival. This approach may be a promising strategy for large HCCs, which traditionally have a poor prognosis with upfront surgery alone.
