1. What federal agency regulates asbestos in the United States? → The EPA regulates environmental asbestos; OSHA regulates workplace asbestos exposure
2. What is the primary pathological process in asbestosis? → Progressive pulmonary fibrosis caused by accumulated asbestos fibers
3. Where does peritoneal mesothelioma develop? → In the peritoneum, the lining of the abdominal cavity
4. What are the three cell types of mesothelioma? → Epithelioid, sarcomatoid, and biphasic (mixed)
5. Which biomarker is most commonly used to help diagnose malignant mesothelioma? → Soluble mesothelin-related peptides (SMRP/mesothelin)
6. What clinical trials are available for mesothelioma patients? → Trials testing immunotherapy, gene therapy, targeted therapy, and combination treatments
7. Which imaging study is most commonly used as an initial screening tool for asbestos-related lung disease? → Chest X-ray (CXR)
8. What are the four types of mesothelioma based on location? → Pleural (lungs), peritoneal (abdomen), pericardial (heart), and testicular
9. Which histological (cell) type of pleural mesothelioma is the most common? → Epithelioid
10. What imaging and diagnostic tests are used to diagnose mesothelioma? → CT scans, PET scans, and tissue biopsy for definitive pathological confirmation
11. What is diffuse pleural thickening (DPT)? → Extensive fibrous scarring of the visceral pleura that can restrict lung function
12. What ethical standards guide Navy professionals in their work? → Integrity, objectivity, confidentiality, and professional competence in all engagements
13. Which type of asbestos fiber is most strongly associated with the development of mesothelioma? → Crocidolite (blue asbestos)
14. During what time period were Navy personnel most likely exposed to asbestos? → 1930s through the 1970s, before asbestos regulations were implemented
15. What are pleural plaques? → Localized areas of fibrous thickening on the parietal pleura
16. What is the typical latency period for asbestos-related diseases to develop after initial exposure? → 20–50 years
17. What are the early symptoms of pleural mesothelioma? → Chest pain, shortness of breath, persistent cough, and unexplained weight loss
18. The dose-response relationship in asbestos exposure means: → Higher cumulative asbestos exposure generally correlates with greater disease risk
19. Is asbestos completely banned in the United States? → No, the U.S. has not fully banned asbestos, though many products and uses are restricted
20. How was asbestos disturbed aboard Navy vessels? → Through routine maintenance, repair, renovation, and the vibration of ship operations
21. What is rounded atelectasis (Blesovsky syndrome) in the context of asbestos exposure? → A benign lung lesion appearing as a rounded mass associated with pleural disease
22. Which areas of a Navy ship had the highest concentration of asbestos-containing materials? → Boiler rooms, engine rooms, and machinery spaces where heat insulation was critical
23. Pericardial mesothelioma affects which structure? → The pericardium, the sac surrounding the heart
24. Compared to non-exposed non-smokers, smokers who were also exposed to asbestos have approximately what increased risk of developing lung cancer? → 50–90 times greater
25. What personal protective equipment is required when working with asbestos? → Respirators with HEPA filters, disposable coveralls, gloves, and eye protection
26. What Navy shipyards had the highest rates of asbestos exposure? → Major shipyards including Norfolk, Portsmouth, Mare Island, and Brooklyn Navy Yard
27. What is the latency period between asbestos exposure and mesothelioma diagnosis? → Typically 20 to 50 years after initial exposure
28. What symptom is most characteristic of advanced asbestosis? → Progressive exertional dyspnea (shortness of breath with activity)
29. What are the main treatment options for mesothelioma? → Surgery, chemotherapy, radiation therapy, immunotherapy, and multimodal combinations
30. What is the staging system used for mesothelioma? → The TNM system assessing Tumor extent, lymph Node involvement, and Metastasis spread
