		        	Abstract:
			       	
			       		
				        
				        	 Purpose:The aim of this study was to compare surgical outcomes after liver resection for hepatocellular carcinoma (HCC) according to tumor size using a large, nationwide cancer registry-based cohort and propensity score matching. 
				        	
				        
				        	Methods:From 2008 to 2015, a total of 12,139 patients were diagnosed with liver cancer and registered in the Korean Primary Liver Cancer Registry. Patients without distant metastasis who underwent hepatectomy as a primary treatment were selected. We performed 1:1 propensity score matching between the small (<5 cm), large (≥5 cm and <10 cm), and huge (≥10 cm) groups. 
				        	
				        
				        	Results:Overall, 265 patients in the small and large groups were compared, and 64 patients each in the large and huge groups were compared. The overall and progression-free survival rates were significantly lower in the large group than in the small group (P < 0.001 and P < 0.001, respectively). Overall survival tended to be poorer in the huge group than in the large group (P = 0.051). The progression-free survival rate was significantly lower in the huge group than in the large group (P = 0.002). 
				        	
				        
				        	Conclusion:Although primary liver resection can be considered even in patients with huge HCC, greater caution with careful screening for recurrence is needed.
