There was a significant difference in LRFS between patients with resection margins of ≥0–1 mm and >1–5 mm ( p = 0.07), and this difference showed a trend when adjuvant radiotherapy was applied ( p = 0.137).
There was a significant difference in LRFS between patients with resection margins of ≥0–1 mm and >1–5 mm ( p = 0.07), and this difference showed a trend when adjuvant radiotherapy was applied ( p = 0.137).
Both margin width and adjuvant radiotherapy had a highly significant positive impact on LRFS ( Table 3 , Figure 1 and Figure 2 ), with the hazard ratio decreasing as the diameter of the surrounding non-reactive tissue increased.
