Number of Examined Pelvic Nodes

Description

Number of Examined Pelvic Nodes is the number of nodes examined based on pelvic nodal dissection. For the Corpus schemas (3) and the Cervix Sarcoma schema, there are 4 data items that record information on the number of positive and examined para-aortic and pelvic lymph nodes. These related data items should be coded from the same procedure * 3899: Number of Examined Para-Aortic Nodes * 3900: Number of Examined Pelvic Nodes * 3901: Number of Positive Para-Aortic Nodes * 3902: Number of Positive Pelvic Nodes

Rationale

Number of Examined Pelvic Nodes is listed as a Registry Data Collection Variable in AJCC. This data item was previously collected as Corpus, CS SSF #4.

Additional Info

**Source documents:** pathology report, imaging reports, physical exam, other statements in medical record

Notes

**Note 1:** **Physician Statement** * Physician statement of examined pelvic nodes can be used to code this data item when no other information is available **Note 2:** **Pelvic lymph nodes** * Iliac, NOS * Common * External * Internal (hypogastric) (obturator) * Paracervical * Parametrial * Pelvic, NOS * Sacral, NOS * Lateral (laterosacral) * Middle (promontorial) (Gerota’s node) * Uterosacral **Note 3:** **Isolated tumor cells** * For this data item, do not include isolated tumor cells (ITCs). **Note 4:** **Related data item** * The number of positive pelvic nodes is recorded in the related data item 3902: Number of Positive Pelvic Nodes.

Coding Guidelines

**1)** Record the number of examined pelvic lymph nodes documented in the medical record. * Number of nodes examined must ALWAYS be **equal to or greater** than the number of nodes positive. * If a lymph node dissection is done and only “nodes” are documented without specifying pelvic or para-aortic, assume they are pelvic **2)** **Code 00** when no lymph nodes are examined by FNA, core biopsy or removal of lymph node(s) (e.g., sentinel lymph node biopsy or lymph node dissection) **3)** **Code 01-99** for the exact number of examined **4)** **Code X1** for 100 or more examined nodes **5)** **Code X2** for nodes examined, but unknown how many **6)** **Code X6** for aspiration or core biopsy of pelvic node(s) **7)** **Code X9** when * Not documented in the medical record * Pelvic lymph nodes not evaluated (assessed) * Unknown if Pelvic lymph nodes not evaluated (assessed)
Code Description
00 No pelvic lymph nodes examined
01-99 1 - 99 pelvic lymph nodes examined
(Exact number of pelvic lymph nodes examined)
X1 100 or more pelvic nodes examined
X2 Pelvic nodes examined; number unknown
X6 No pelvic lymph nodes removed, but aspiration or core biopsy of pelvic node(s) only
X8 Not applicable: Information not collected for this case
(If this item is required by your standard setter, use of code X8 will result in an edit error.)
X9 Not documented in medical record
Cannot be determined, indeterminate if examined pelvic nodes present
Pelvic lymph nodes not assessed or unknown if assessed
