“…For example, the mean Tac trough blood concentration at 3 months was 8.2 in our population vs. 9.2 in Carenco study, and the overall mean Tac concentration at 3 months for patients with de novo malignancy was in our population 8.8 (+/-2.4) vs. 8.6 (+/-2.6) for patient without de novo cancer (10.8 vs. 8.9 in Carenco study). Regarding HCC recurrence, our results confirm that a reduced exposure to CNIs (for instance by using sirolimus) within the first months after LT could be associated with decreased risk of HCC recurrence [30,31]. Similarly, conversion from CNI to sirolimus is able to prevent squamous-cell carcinoma recurrence in kidney transplant recipients [32].…”
