Inquiry Details

2018 EOD Manual. Regional Nodes
Question:
EOD 2018/Regional Nodes--Corpus Uteri: Are lymph nodes found on imaging post-surgery included in Extent of Disease (EOD) Regional Nodes if surgery is already completed? See Discussion.
Discussion:
11/16/20: Patient diagnosed with endometrial cancer on by MRI of the pelvis; 11.5 cm uterine mass consistent with cancer with no lymphadenopathy.
1/6/21: Patient had a total abdominal hysterectomy/bilateral salpingo-oophorectomy and pelvic lymph node dissection. Operative report stated patient had mildly enlarged bilateral pelvic nodes.
Path report: Endometrioid adenocarcinoma with invasion of the serosa. Five bilateral pelvic nodes were sampled and negative. Originally, staging had patient as node negative.
1/22/21: Patient had post op imaging done that showed metastatic retroperitoneal, aortocaval, and possibly left iliac lymph nodes. Physician changed staging to include the lymph node involvement.
Answer:
EOD includes all information available within four months of diagnosis in the absence of disease progression or upon completion of surgery(ies) in first course of treatment, whichever is longer. Since the imaging was within the four-month window, and the nodes could have been positive during surgery but not assessed by the surgeon, use the information from the imaging.
Assign code 600 for EOD Regional Nodes for involvement of the aortocaval and retroperitoneal nodes (para-aortic nodes), size unknown.
