Surgical management of pediatric hepatocellular carcinoma: An analysis of the National Cancer Database
Journal of Pediatric Surgery(2021)
摘要
Purpose
This study evaluates overall survival (OS) between liver transplantation (LT) and liver resection (LR), while assessing the effect of margin status, in children with hepatocellular carcinoma (HCC).
Methods
The National Cancer Database was queried (2004–2015) for children (<18 years) with non-metastatic HCC undergoing surgery.
Results
One hundred six children with HCC treated surgically (LT 34, LR 72) were identified. For T1 stage, no difference in OS was observed for LT vs. margin-negative liver resection [LR(−)] (log-rank, p = 0.47). For T2/T3/T4 stage, no difference in OS was observed for LT vs. LR(−) (log-rank, p = 0.08); both subgroups exhibited superior OS vs. margin-positive liver resection [LR(+)] (log-rank, LT vs. LR(+): p = 0.001 and LR(−) vs. LR(+): p = 0.04). On multivariable Cox regression: (i) histology (fibrolamellar vs. not) and T stage (T1 vs. T2/T3/T4) were not associated with OS (both p = 0.06), (ii) chemotherapy and size >5 cm were not associated with OS (both p ≥ 0.42), (iii) when compared to LT, both LR(−) (p = 0.03) and LR(+) (p = 0.001) were associated with increased likelihood of mortality.
Conclusion
Although margin-negative resection may be obtained with LT or LR, early LT consultation is warranted for children at high risk of LR(+) regardless of Milan criteria due to the negative impact of LR(+) on OS.
Type of study
