"notes" : "**Note 1:** Physician statement of Visceral and Parietal Pleural Invasion can be used to code this data item when no other information is available.\n\n**Note 2:** *Chapter 36: Lung* of the AJCC Staging Manual 8th edition includes a standardized and precise definition of pleural/elastic layer invasion (PL). \n\nThere are four categories:\n* PL0 - Tumor that is surrounded by lung parenchyma or invades superficially into the pleural connective tissue beneath the elastic layer but falls short of completely traversing the elastic layer of the pleura\n* PL1 - Tumor that extends through the elastic layer\n* PL2 - Tumor that extends to the surface of the visceral pleura\n* PL3 - Tumor that extends to the parietal pleura or chest wall\n\nCategories PL1 and PL2 are considered pleural invasion for staging and are classified as at least a T2. PL3 is classified as at least a T3. PL0 is not considered pleural invasion for TNM staging, and the T category is assigned based on other criteria. Other criteria can also raise the T category for PL1-3 tumors. \n\nWhen pathologists have difficulty assessing the relationship of the tumor to the elastic layer on routine hematoxylin and eosin (H and E) stains, they may perform a special elastic stain to make the determination.\n\n**Note 3:** An FNA is not a histologic specimen and is not adequate to assess pleural layer invasion. If only an FNA is available, code 9.\n\n**Note 4:** Code 9 if there is microscopic confirmation and there is no mention of visceral pleural invasion.",
