Overview
- Antibodies to cytokeratin proteins are positive, differentiating these neoplasms from many sarcomas but not adenocarcinomas.
- The absence of staining with CEA or Leu-M1 differentiates them from adenocarcinomas.
- Recent evidence shows that Wilms’ Tumor Antigen 1 may help differentiate mesothelioma from adenocarcinoma.
Other Diagnostic Studies
Laparoscopy, Thoracoscopy, and Pleuroscopy
- Thoracoscopy or pleuroscopy may help in the diagnosis of mesothelioma.[1]
- Laparoscopy may be used to diagnose and treat selected cases of well-differentiated papillary mesothelioma associated with pelvic endometriosis.[2]
Biopsy
- Biopsy is helpful in the diagnosis of mesothelioma.[3]
- Procedures performed for biopsy may include:[3]
- Fine-needle (FNA) aspiration biopsy of the lung
- Thoracoscopy
- Thoracotomy
- Peritoneoscopy
- Open biopsy
Position Emission Tomography
- Positron emission tomography is becoming useful in two clinical settings:[4]
- Differentiating between benign and malignant asbestos-related pleural thickening
- Assessing for nodal metastases
- In addition, there appears to be a correlation between the degree of FDG uptake and the biological aggressiveness of the tumor, which may help to guide treatment.[4]
Fluorescence In Situ Hybridization (FISH)
- FISH may be helpful in the diagnosis of mesothelioma. It helps in distinguishing malignant mesothelioma from reactive mesothelial cells in effusions.[5]
- Mutlitarget FISH assay may be used to detect chromosomal abberations (chromosomes 3, 7, 17, and 9p21).
- FISH technique may also be used to explore the alternative mechanism of tumor suppressor gene inactivation by methylation of p16, p14, and p15 gene in the pathogenesis of mesothelioma.[5]
