CD209 and thymoma: Conversely, the high expression of CD209 predicted poor overall survival in KIRP (kidney renal papillary cell carcinoma) (p = 0.039, HR = 1.87), LUSC (p = 0.0061, HR = 1.48), KIRC (kidney renal clear cell carcinoma) (p = 0.031, HR = 1.42), ESCC (esophageal squamous cell carcinoma) (p = 0.058, HR = 2.42), LHC (liver hepatocellular carcinoma) (p = 0.064, HR = 1.41), and THYM (thymoma) (p = 0.039, HR = 340295023.97) (Figure 3).
