A total of 145 Liver transplantation (LT) recipients with hepatocellular carcinoma (HCC) were retrospectively enrolled at Kaohsiung Chang Gung Memorial Hospital between 2006 and 2019. Clinical records from 7 days before LT (pre-LT) to 1 year after LT (post-LT) were analysed. In a prospective study from March 2022 to June 2023, 20 lymphopenia and 25 non-lymphopenia HCC recipients were enrolled, and a phenotypic analysis of peripheral blood lymphocytes was performed using multiparameter flow cytometry.
A total of 145 Liver transplantation (LT) recipients with hepatocellular carcinoma (HCC) were retrospectively enrolled at Kaohsiung Chang Gung Memorial Hospital between 2006 and 2019. Clinical records from 7 days before LT (pre-LT) to 1 year after LT (post-LT) were analysed including overall survival, recurrence-free survival, association between clinical parameter with mortality, patient characteristics by pre-lymphopenia and post-lymphopenia levels and lymphocyte status of HCC patients with usage of different immunosuppressants. In prospective study from March 2022 to June 2023, 20 lymphopenia and 25 non-lymphopenia HCC recipients were enrolled, and a phenotypic analysis of peripheral blood lymphocytes was performed using multiparameter flow cytometry to identify the major immune cell subsets and the characteristics of patients in the prospective cohort between pre-LT lymphopenia and non-lymphopenia groups.

| Measure | Description | Time Frame |
|---|---|---|
| Persistent lymphopenia predict poor overall survival | The clinical records of 145 patients with HCC from seven days pre-LT to one-year post-LT illustrated that the longitudinal values of lymphocytes were persistently low in patients with peritransplant high neutrophil lymphocyte ratio, indicating a significant decrease in survival rate when compared to other patients. | From 2006 to 2019 |
| T cell and its subtype were mainly decrease in pre-LT lymphopenia population of HCC patient | A significant decrease in cell counts and percentage of overall T cells in the peritransplant lymphopenia group. In particular, the counts of T cell subsets, T helper cells, and cluster of differentiation 8 (CD8+) cytotoxic/activated T cells significantly decreased in the peritransplant lymphopenia group with all of their naïve, effector, and memory forms. | From March 2022 to June 2023 |
| Long-term peri-LT lymphopenia HCC recipients is associated with increased sirolimus use and decreased tacrolimus use | In the subset of 116 of 145 HCC recipients (80%) who did not experience or recover from lymphopenia, no significant associations were observed with immunosuppressant use. Surprisingly, HCC recipients with long-term peritransplant lymphopenia exhibited a significant association with increased sirolimus use (p = 0.024) and decreased tacrolimus use (p = 0.001), whereas those with post-LT lymphopenia showed no association with the use of different immunosuppressants. | From 2006 to 2019 |
