This field is required for cases starting 01/01/2010

This data item identifies whether lung is an involved metastatic site. The six Mets at Diagnosis-metastatic sites data items provide information on specific metastatic sites for data analysis.

Code	Description

Code	Description
0	None; no lung metastases
1	Yes; distant lung metastases
8	Not applicable
9	Unknown whether lung is an involved metastatic site Not documented in patient record

Coding Instructions

1. Code information about lung metastases only (discontinuous or distant metastases to lung) identified at the time of diagnosis. Do not code pleural or pleural fluid involvement in this data item.

Note: See code 1 in “Mets at Diagnosis--Other” for pleural nodules, malignant pleural or pericardial effusion.

a. Lung involvement may be single or multiple

b. Information about lung involvement may be clinical or pathological

c. Code this data item whether or not the patient had neoadjuvant (preoperative ) systemic therapy unless determined to be disease progression

d. Code this data item for all solid tumor schemas (including Kaposi Sarcoma and Ill-Defined Other [includes unknown primary site]) and the following Hematopoietic schemas except as noted in 2.c. and 2.d.

i. Lymphoma Ocular Adnexa 00710

ii. Lymphoma 00790

iii. Lymphoma-CLL/SLL 00795

iv. Mycosis Fungoides (MF) 00811

v. Primary Cutaneous Lymphoma (excluding MF and SS) 00812

vi. HemeRetic 00830 (excluding primary sites C420, C421, C423, C424)

2. Use of codes: Assign the code that best describes whether the case has lung metastases at diagnosis.

a. Use code 0 when the medical record

i. Indicates that there are no distant (discontinuous) metastases at all

ii. Confirms the tumor is benign (/0), borderline (/1), or in situ (/2)

iii. Includes a clinical or pathologic statement that there are no lung metastases

v. Indicates that the patient has distant (discontinuous) metastases but lung is not mentioned as an involved site

Note: A single tumor in each lung is two primaries, unless proven to be metastatic (see Solid Tumor Rules for Lung).

Example: Use code 0 when the patient has metastasis to liver and brain but not lung.

b. Use code 1 when the medical record

i. Indicates that the patient has distant (discontinuous) metastases and lung is mentioned as an involved site

ii. Indicates that lung is the primary site and there are metastases in the contralateral lung

iii. Indicates that the patient is diagnosed with an unknown primary (C809) and lung is mentioned as a distant metastatic site

Note: Do not assign code 1 for a lung primary with multifocal involvement of the same lung.

c. Use code 8 (Not applicable) for the following

i. Any case coded to primary site C420, C421, C423, or C424

ii. Plasma Cell Disorders 00822

d. Use code 9 when it cannot be determined whether the patient specifically has lung metastases. In other words, use code 9 when there are known distant metastases but it is not known whether the distant metastases include lung.

For more information about schemas and schema IDs, go to the SSDI Manual, Appendix A.

iv. Includes imaging reports that are negative for lung metastases
