Prognostic Value of Histology-specific Ki-67 Labeling Index Cutoffs in Stage I-III Non-small Cell Lung Cancer
Background/Aim: Although the Ki-67 labeling index (LI) is widely used as a marker of tumor proliferative activity, its prognostic utility in non-small cell lung cancer (NSCLC) remains uncertain because of heterogeneous study populations and the lack of standardized, histology-specific cutoff values. Patients and Method...
