Summary of metastatic sites in BoM (A) and Non-BoM group (B). Multi-organ metastases (≥3) were more common in BoM group (p ≤ 0.001). In BoM group, brain (p = 0.003), liver (p ≤ 0.001), and adrenal gland (p = 0.001) were more common, while lung (p = 0.003) and pleural (p = 0.05) were more significant in Non-BoM group. Distant lymph node metastases were similar in 2 groups (p = 0.509, C).
