BACKGROUND: While resection is a recommended treatment for patients with stage 1 hepatocellular carcinoma (HCC), it remains controversial for multifocal disease. We sought to identify patients with multifocal HCC with survival after resection similar to patients with clinical stage 1 HCC. METHODS: The National Cancer Database was queried to identify patients that underwent resection for HCC. RESULTS: In this study, 2990 patients with a single tumor, and 1087 patients with multifocal disease confined to one lobe underwent resection. In the multifocal cohort, patients with clinical stage 3 (HR 1.54, CI 1.31–1.81, p < 0.0001) or 4 (HR 2.27, CI 1.57–3.29, p < 0.0001) disease, and those with moderately-differentiated (HR 1.32, CI 1.06–1.64, p = 0.012) or poorly differentiated/undifferentiated tumors (HR 1.53, CI 1.20–1.95, p = 0.0006) were associated with worse overall survival (OS). There was no difference in OS between patients with well-differentiated clinical stage 2 multifocal HCC and those with all grades of clinical stage 1 HCC (median of 84.8 (CI 66.3–107.2) vs 76.2 months (CI 71.2–81.3), respectively, p = 0.356). CONCLUSIONS: Patients with well-differentiated, clinical stage 2 multifocal HCC confined to one lobe experience similar OS following hepatic resection to patients with clinical stage 1 disease. These findings may impact the management of select patients with multifocal HCC.

BACKGROUND: Adrenocortical carcinoma (ACC) is an aggressive malignancy that frequently metastasizes to the liver. Given the limitations of systemic therapy in this setting, we sought to determine characteristics associated with a two-fold increase in survival with surgical management compared to what has been reported with chemotherapy alone (∼12 months). METHODS: Patients who underwent resection/ablation at our institutions for ACC liver metastases were identified. Those who survived between 12–24 months after metastasectomy were excluded, as the aim was to characterize patients who most clearly benefited from these procedures. Clinicopathologic and treatment characteristics were assessed for associations with survival. RESULTS: Sixty-two patients met inclusion criteria, of whom 44 survived greater than 24 months and 18 survived less than 12 months. Patients with extended survival were less likely to have functioning tumors (p=0.047), had fewer liver metastases (p=0.047), and a longer disease-free interval (DFI) (median 17.6 vs 2.3 months, p
