B cells attracting NK cells in CD74 CD44 MIF neighborhoods was linked to better survival at 20 μm (log-HR = -1.48, p = 0.033) and 60 μm (log-HR = -1.73, p = 0.0018), indicating that NK cell presence close to B cells in these regions may contribute to an effective anti-tumor response. Here, CD74 is linked to neoplasm.
