Patients with pre-operative KPS score <70 demonstrated significant improvement 6-weeks after surgical

resection. Paired parallel axis dot plot showing significant functional improvement for patients

with pre-op KPS score <70 following the surgical resection (p<0.0001) (A) ,while no significant changes were observed in pre-op KPS score ≥ 70 group (B). Preoperative NANO scale improved significantly at postoperative follow-up assessment (P = 0.0036) from a preoperative median score of 3 to 1 at follow-up (C).
