Difference in prognosis between PPCP and APCP. (A) Comparable overall prognosis between PPCP and APCP (χ2 test, P > 0.05). (B) Significant prognostic association with initial resection extent (Fisher’s exact test, P < 0.01, total vs. partial). (C) Progression-free survival parity post-last surgery (Kaplan–Meier curves, P > 0.05).
