Scenario: 2022
- colonoscopy+ rectal adenocarcinoma { Lymphovascular Invasion not mentioned on path report}
- patient treated with neoadjuvant xrt/chemo
- after neoadjuvant treatment patient undergoes resection path report states Lymphovascular Invasion: Not Identified
Question: How would you code Lymphovascular invasion?
- 0 Lymphovascular Invasion stated as Not Present
- 9 Unknown/Indeterminate/not mentioned in path report
Answer: 9
Rationale: STORE 2022
f. For cases treated with neoadjuvant therapy, refer to table below in order to code this field. However, if documentation in the medical record indicates information that conflicts with this table, code lymphovascular invasion with the documentation in the medical record.
- If LVI was present prior to neoadjuvant therapy (codes 1-4) but LVI was not present after neoadjuvant therapy (codes 0 or 9), code the LVI to present (codes1-4).
- the LVI was not present prior to neoadjuvant therapy (codes 0 or 9), but LVI was
present after neoadjuvant therapy (codes 1-4), code LVI to present (codes 1-4).
