Patients with PB-type tumours with high CD56+ NK/NKT-cell density who had not received adjuvant therapy had a significantly prolonged OS (p = 0.008) compared to the reference group (low NK/NKT cell count, not receiving adjuvant therapy) as did patients with I-type tumours (p = 0.012) (Fig 3). The gene discussed is NCAM1; the disease is neoplasm.
