Table 7. Specificities of patient’s lung biopsy diagnostic down-regulated markers.

BC: breast carcinoma; HGSOC: high-grade serous ovarian carcinoma; LUAD: lung adenocarcinoma; LUSC: lung squamous cell carcinoma; PM: peritoneal mesothelioma

Note: The pertinent up-regulated marker, calretinin, should not be used as a standalone finding due to high sensitivity for malignant peritoneal mesothelioma and ~10% specificity for adenocarcinoma
