Mets at DX - Distant LN
Organization | Field Name | ID | Required |
|---|---|---|---|
KCR | Mets at DX - Distant LN (MetsDistLymphNodes) | 30685 | yes |
NAACCR | Mets at Dx-Distant LN | yes |
Field length: 1
This field is required for cases starting 01/01/2016
This data item identifies whether distant lymph node(s) are an involved metastatic site. The six Mets at Diagnosis-metastatic sites data items provide information on specific metastatic sites for data analysis.
Code | Description |
|---|---|
0 | None; no distant lymph node metastases |
1 | Yes; distant distant lymph nodemetastases |
8 | Not applicable |
9 | Unknown whether distant lymph node(s) is an involved metastatic site Not documented in patient record |
Coding Instructions
Note 1: Use AJCC TNM to determine regional versus distant lymph nodes.
Note 2: Assign code 0 (None) for unknown primaries, unless involved lymph nodes are stated to be distant lymph nodes.
Note 3: Placental lymph node involvement for placental primaries is classified as distant lymph node involvement (M1) and recorded in this data item.
1. Code information about distant lymph node(s) metastases only (metastases to distant lymph nodes) identified at the time of diagnosis
a. Distant lymph node involvement may be single or multiple
b. Information about distant lymph node 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. Do not code this data item for regional lymph node involvement
e. 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 (excluding primary sites C770-C779; see 2.c.)
iii. Lymphoma-CLL/SLL 00795 (excluding primary sites C770-C779; see 2.c.)
iv. Mycosis Fungoides (MF) 00811
v. Primary Cutaneous Lymphoma (excluding MF and SS) 00812
vi. HemeRetic 00830 (excluding primary sites C420, C421, C423, C424, see 2.c.)
2. Use of codes: Assign the code that best describes whether the case has distant lymph node 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 distant lymph node metastases
iv. Includes imaging reports that are negative for distant lymph node metastases
v. Indicates lymph nodes are involved, but there is no indication whether they are regional or distant
vi. Indicates that the patient has distant (discontinuous) metastases but distant lymph node(s) are not mentioned as an involved site
Example: Use code 0 when the patient has metastasis to lung and liver but not distant lymph node(s).
b. Use code 1 when the medical record
i. Indicates that the patient has distant (discontinuous) metastases and distant lymph node(s) are mentioned as an involved site
c. Use code 8 (Not applicable) for the following
i. Any case coded to primary site C420, C421, C423, C424, or C770-C779
ii. Plasma Cell Disorders 00822
d. Use code 9 when it cannot be determined whether the patient specifically has distant lymph node metastases. In other words, use code 9 when there are known distant metastases but it is not known
whether the distant metastases include distant lymph node(s).
