研究目的：
The investigators established three prospective cohorts of patients with BCLC stage 0-A HCC, based on different surgical approaches (open, laparoscopic and robotic). After 5 years of follow-up, the investigators used propensity score matching (PSM) to reduce selection bias and then compared the long-term oncological outcomes of the three different surgical approaches, which might provide high-level evidence in non-randomized observational studies.
