Abstract:Objective: To analyze the relationship between tumor budding and clinicopathological features and prognosis of prostate cancer (PCa). Methods: The clinical data of 101 patients with PCa who underwent radical resection in the hospital were collected between January 2018 and December 2021.Two pathologists used the tumor budding count and grading method proposed by Ueno et al.to determine the tumor budding of PCa tissue,and Kappa consistency test was used to evaluate the consistency.The relationship between clinicopathological features and tumor budding grading was analyzed among patients with PCa.The survival rate of patients with different tumor budding grades was compared among patients with follow-up time≥2 years. Results: The minimum and maximum tumor budding counts of 101 patients with PCa were 0 and 31,with the median of 4.There were 45 cases of high-grade tumor budding,56 cases of low-grade tumor budding,and 21 cases without budding.The two pathologists had good consistency in judging the tumor budding grading (Kappa coefficient=0.880,P<0.05).Among patients with PCa,the high-grade rate of tumor budding was higher among patients with high TNM stage,high Gleason score,lymph node metastasis,capsular invasion,seminal vesicle invasion and negative E-cadherin expression (P<0.05).62 cases were followed up for ≥2 years,including 26 cases of high-grade tumor budding and 36 cases of low-grade tumor budding.Log-rank test showed that the survival rate of patients with high-grade tumor budding was significantly lower than that of patients with low-grade tumor budding (P<0.05). Conclusion: Tumor budding is closely related to the clinicopathological feature of PCa,and can predict the prognosis of patients with PCa.
