In univariate analysis, Hu and colleagues [23] found no association between OS and high or low CD68 infiltration when measured in the tumour stroma and islets separately (stroma HR 1.44, 95% CI 0.85–2.42; p = 0.17: islet HR 1.38, 95% CI 0.8–2.38; p = 0.25). The gene discussed is CD68; the disease is neoplasm.
