Kaplan-Meier curves depicting progression-free survival (PFS) and overall survival (OS) for patients G1/G2 increase to G3. (A) Patients with G1/G2 increase to G3 had decreased PFS than patients with stable G1/2 (P=0.012). (B) Patients with G1/G2 increase to G3 had decreased OS than patients with stable G1/2 (P=0.027).
