A total of 38 cases of No. 10 LN metastasis were identified in the model development group, yielding a transfer rate of 9.6. The median follow-up period was 33 (range, 18-66) months. The 3-year overall survival rate was 72.3%. The 3-year OS for patients with No. 10 LN metastasis was significantly shorter than that for patients without No. 10 LN metastasis (51.6% vs. 74.5%, P = 0.002) (Figure 1).
