The correlation between CTA- and SALL4-specific T cell responses and recurrence was analyzed, and a significantly stronger T cell response to tumour antigens was found in patients without recurrence than in those who experienced relapse (177.65 ± 61.21 SFUs/106 cells vs. 49.33 ± 17.60 SFUs/106 cells, P = 0.0403, Fig. 4). The gene discussed is SALL4; the disease is neoplasm.
