Background & Aims Liver transplantation (LTx) is one of the most effective treatments for hepatocellular carcinoma (HCC); however, tumour recurrence after LTx often leads to poor outcomes. This study investigated the value of circulating tumour cells (CTCs) as a predictor of recurrence following LTx in patients with HCC. Methods This analysis included 193 patients with HCC who underwent LTx at our institute and accepted pre‐ and post‐operative CTC detection; 38 were selected for serial CTC monitoring. The predictive value of CTCs for tumour recurrence in patients with HCC following LTx was evaluated. Single‐cell whole genome sequencing was used to characterize CTCs. Results Overall, the CTC burden decreased after LTx ( P < .05). Post‐operative CTC count ≥ 1 per 5 mL peripheral blood was identified as a potential biomarker for predicting tumour recurrence after LTx, especially in patients with no detectable CTCs prior to LTx and negative tumour serological biomarkers. The predictive value of post‐operative CTC count ≥ 1 per 5 mL blood was retained in patients who did not meet the Milan criteria, University of California San Francisco (UCSF) criteria, or Fudan criteria (all P < .05). Furthermore, post‐operative serial CTC detection may be useful in post‐surgical surveillance for HCC recurrence. Conclusions CTCs may be a useful biomarker to evaluate recurrence risk following LTx in patients with HCC. Evaluation based on CTC detection may enhance the post‐transplant management of HCC, and improve the therapeutic efficacy of LTx.
