NXN and neoplasm: No differences were observed in MAIT cell frequency when OAC patients were classified by TRG, with scores of 1–2 indicating a good response to neo-adjuvant treatment, TRG3 indicating no response, and TRG4-5 indicating tumor progression, when tumor MAIT cell frequencies (Figure 7C) (n = 24) and blood (Figure 7D) (n = 43) were assessed.
