Development of a Prognostic Score for Papillary Thyroid Carcinoma Incorporating Ki-67 Labeling Index: MASSIN-K.
BACKGROUND We previously demonstrated that the Ki-67 labeling index (LI), a marker of cell proliferation, strongly predicts prognosis in patients with papillary thyroid carcinoma (PTC). We subsequently developed a prognostic scoring system incorporating Ki-67 LI. METHODS We enrolled 8540 patients with PTC who underwe...
