Surgical resection of early stage hepatocellular carcinoma: balancing tumor biology with the host liver

435 Background: There is no consensus regarding treatment for HCC variants. Clinical outcomes of HCC variants differ from pure HCC. The aim of this study is to compare clinicopathological characteristics, treatment, and outcomes of HCC variants with pure HCC. Methods: Patients with HCC and variants with 8170/3-8175/3 and 8180/3 ICD-O-3 codes were identified from National Cancer Database between 2004 and 2013. Univariate and multivariate survival analyses were conducted to analyze the association between histology and overall survival (OS). Results: 80,280 patients were identified; pure HCC 78,461 (97.7%), fibrolamellar (FLHCC) 310 (0.4%), scirrhous 161 (0.2%), spindle cell 72 (0.1%), clear cell 487 (0.6%), pleomorphic 23 (0.0%), and combined HCC and cholangiocarcinoma (mixed HCC) 766 (1.0%). 76.7% were male and 72% Caucasian. The mean age was similar in all except FLHCC (37.9 vs. 60.9-64.1 years, p < 0.001). Liver transplant was performed in 10.1% of pure HCC, 14.5% of mixed HCC, 16.2% of scirrhous, 6.9% of spindle cell, 8.8% of clear cell, 8.7% of pleomorphic, and 3.2% of FLHCC (p < 0.001). Pure HCC (10.57%) underwent surgical resection less often than variants; FLHCC (54.8%), clear cell (34.5%), mixed HCC (29.8%), spindle cell (33.3%), pleomorphic (34.8%), and scirrhous (9.9%) (p < 0.001). Ablation was performed in 9.8% of pure HCC, and in up to 8.7% of HCC variants. More than a third of all patients received chemotherapy; pure HCC (42.3%), mixed HCC (38.5%), scirrhous (31.1%), spindle cell (36.1%), clear cell (35.5%), pleomorphic (34.8%), and FLHCC (41.3%). FLHCC had the best 5-year OS (38.7%), spindle cell and pleomorphic had the worst (9.6% and 13.0%). In univariate and multivariate analyses, fibrolamellar histology, female sex, diagnosis between 2009 and 2013, treatment at academic center, well/moderately differentiated histology, early stage, and chemotherapy was associated with better OS compared to pure HCC, male sex, diagnosis between 2004 and 2008, treatment at community cancer program, poorly differentiated, late stage, and no chemotherapy (p < 0.001). Conclusions: HCC variants underwent surgical resection more often than HCC. FLHCC had the best 5-year OS. Liver transplant is commonly performed in HCC variants.

AbstractSince the Milan criteria were accepted as the gold standard, liver transplantation has been widely performed as a curative treatment for early-stage hepatocellular carcinoma (HCC). The outcome of liver transplantation in early-stage HCC is excellent; however, the Milan criteria are strict, and therefore, only limited numbers of patients can benefit from liver transplantation. Many HCC patients are diagnosed at an advanced stage, which falls outside the Milan criteria, so it has been proposed over the last two decades that liver transplant surgeons should perform liver transplantation in locally advanced HCC, when presenting without recurrence. Several trials exploring the upper limits of liver transplantation have been performed, and extensive research on tumor biology has enabled the expansion of liver transplant indication for HCC. Simultaneously, locoregional therapy for advanced HCC was found to be an effective procedure when used to distinguish potentially transplantable patients. This treatment approach, known as a downstaging strategy, has been developed over the last two decades and became an essential treatment option for locally advanced HCC. In this article, the current strategies of liver transplantation for the treatment of locally advanced HCC are reviewed.
