Validation of New York/California Score in the Preoperative Period of Liver Transplant for Hepatocellular Carcinoma at University of Campinas's Hospital.

ABSTRACT

Liver transplant is the main treatment for hepatocellular carcinoma and there is currently an important demand from patients waiting in transplant queues. Thus, it is extremely important to improve the criteria for selecting patients who will undergo transplant to mitigate graft loss and reduce cases of recurrence. Thus, it becomes necessary to use models, such as the New York/California (NYCA), that include alpha fetoprotein as a marker of recurrence and prognosis. The aim of this study was to assess whether the NYCA score correlated with the presence of tumor recurrence after transplant in patients undergoing orthotopic liver transplant at the Clinics Hospital of the University of Campinas. We had 214 patients undergoing liver transplant who met the inclusion Milan criteria. The age of the patients ranged from 34 to 77 years, with a median age of 61 years. The mean waiting time on the transplant list was 6.12 months. After calculating the NYCA score, it was possible to stratify 13 patients (6.1%) as high risk, 64 patients (29.9%) as medium risk, and 137 patients (64%) as low risk. Patients with recurrence had higher scores with a mean of 4 points in relapse and 2 points in the absence of relapse (P = .0011). Patients with recurrence had statistically higher high- and medium-risk scores (P = .0010). Therefore, the NYCA score was higher in patients with recurrence. Therefore, in this study, our findings suggest the possibility of using the NYCA score as an aid to detect patients with a higher risk of tumor recurrence.
