CD163 and non-small cell lung carcinoma: Survival analysis demonstrated that low numbers of CD163+ macrophages are a factor of good prognosis for squamous cell NSCLC (HR = 0.3438, p = 0.0302) and NSCLC in general (HR = 0.5008, p = 0.0392), while high numbers of CD204+ macrophages are a good prognosis indicator for the early stages of NSCLC (HR = 0.3187, p = 0.0451) (Figure 4).
