Figure 2:
Incidence of early recurrence detected during radiation planning stratified by use of post-operative PET/CT (A), number and type of clinicopathologic risk factors (B), time from initial surgery to simulation (C). IRF = Intermediate risk factor, including pT3–4, pN2–3, margin (≤ 5mm), thickness > 5mm, PNI or LVI. HRF = high-risk factor, including ECE or positive margins.
