Significance of EGFR and PTEN Expression and PLR and NLR for Predicting the Prognosis of Epithelioid Malignant Peritoneal Mesothelioma

Figure 1

Expression of EGFR and PTEN in epithelioid MPeM tissue. EGFR was based on a membranous staining pattern, and PTEN was detected in the cytoplasm (a and e). Negative for EGFR and PTEN expression. (b and f) Weak expression of EGFR and PTEN in epithelioid MPeM tissue; minority of peritoneal cells are stained yellow. (c and g) Moderate expression of EGFR and PTEN in epithelioid MPeM tissue; a medium quantity of peritoneal cells are stained yellow or brown. (d and h) Strong expression of EGFR and PTEN in epithelioid MPeM tissue; majority of peritoneal cells are stained yellow or brown (×400).
