This study analyzed the relationship between the expression of Ki67 and the efficacy of postoperative adjuvant TACE in patients with HCC, and confirmed that when Ki67 was highly expressed, adjuvant TACE after liver resection could effectively reduce postoperative tumor recurrence and significantly improve the long-term survival rate, while when the expression of Ki67 was low, PA-TACE may result in a poor prognosis. Here, MKI67 is linked to neoplasm.
