NCAM1 and hepatocellular carcinoma: For example, thermal ablation has been demonstrated to promote increases in the frequency and function of CD3-CD56+NK cells in the peripheral blood of patients with HCC, and is associated with recurrence-free survival (51), whereas radiation therapy has been found to have a significant effect on the levels of peripheral NK and NKT-like cells, with a higher percentage of NKT-like cells being found to be associated with a longer OS in HCC patients (52).
