Programmed cell death protein 4 expression in renal cell carcinoma, penile carcinoma and testicular germ cell cancer

Figure 1 Histopathological staining results of malignant (pT2) renal tissue (A) and of a control sample (B) (haematoxylin and eosin staining, magnification factor: 40 ×).

Figure 2 Histopathological staining results of malignant (pT3) penile tissue (A) and of a control sample (B) (haematoxylin and eosin staining, magnification factor: 40 ×).

Figure 3 Percentual distribution of core intensity (A), cytoplasmatic-(B) and programmed cell death 4 staining results in correlation to renal cell carcinoma subtype and controls. Left weak/negative staining, right strong/positive staining result. RCC: Renal cell carcinoma; ccRCC: Clear cell RCC; pRCC: Papillary RCC; chRCC: Chromophobe RCC; sRCC: Sarcomatoid RCC.

Figure 4 Percentual distribution of core (A) and cytoplasmic programmed cell death 4 (B) levels in penile carcinoma tissue compared to metastasies and controls. Left weak/negative staining, right strong/positive staining result.

Figure 5 Percentual distribution of core (A) and cytoplasmatic (B) programmed cell death 4 staining results in correlation to T-stage of penile carcinoma and controls. Left weak/negative staining, right strong/positive staining result.

Figure 6 Percentual distribution of core (A) and cytoplasmatic (B) programmed cell death 4 staining results in correlation to Seminoma-, non-seminomatous germ cell tumor and controls. Left weak/negative staining, right strong/positive staining result. NSGCT: Non-seminomatous germ cell tumor.
