Correlation between Ki-67 or Profilin-1 Expression Levels, Clinicopathological Characteristics and Postoperative Prognosis in Patients with Bladder Cancer.
BACKGROUND: Bladder cancer is the most common malignancy of the urinary system, and the search for new and reliable biomarkers has important clinical significance for the personalized treatment of bladder cancer. This study aims to explore the correlation between nuclear proliferation antigen (Ki-67) or Profilin-1 (PFN1) levels, clinicopathological characteristics, and postoperative prognosis in patients with bladder cancer.
METHODS: Patients with bladder cancer who underwent transurethral resection of bladder cancer tumor in The Fourth Affiliated Hospital of Soochow University, hospital from January 2019 to January 2021 were selected as the study group (n = 60), and patients with benign lesions of bladder cancer during the same period were selected as the control group (n = 60). The expression of Ki-67 and PFN1 in tumor and bladder tissues of the two groups was analyzed. Ki-67 recorded the patient's pathological parameters and calculated the patient's postoperative prognosis. The correlation between Ki-67 and PFN1 expression levels, pathological parameters, and postoperative prognosis was analyzed.
RESULTS: The positive expression rates of Ki-67 and PFN1 in the study group were 63.33% and 73.33%, respectively, which were significantly higher than the positive expression rates in the control group (χ2 = 14.803, 17.757, p < 0.001). The positive expression rates of Ki-67 and PFN1 were related to histological grade, clinical stage, infiltration, and lymph node metastasis, and the differences were statistically significant (p < 0.05). Bladder cancer patients with non muscle-invasive bladder cancer (NMIBC), high-grade histological grade, Ta~T1 clinical stage, invasive, and lymph node metastasis have a higher Ki-67 positive expression rate than bladder cancer patients with muscle-invasive bladder cancer (MIBC), low-grade histological grade, T2~T4, non-invasive, and no lymph node metastasis. The high expression level of Ki-67 has little relationship with gender, age, tumor diameter, and vascular invasion (p > 0.05). The survival time and three-year survival rate of the Ki-67 positive expression group were significantly lower than those of the Ki-67 negative expression group (p < 0.05). The survival time and three-year survival rate of the PFN1 positive expression group were significantly lower than those of the PFN1 negative expression group (p < 0.05).
CONCLUSION: The positive expression rates of Ki-67 and PFN1 in bladder tumor tissue are significantly higher than those in bladder tissue, and pathological pattern, histological grade, clinical stage, infiltration, and lymph node metastasis are related to the positive expression rates of Ki-67 and PFN1, and different genders, ages, tumors diameter and vascular invasion are not related to the positive expression rates of Ki-67 and PFN1. The survival time and three-year survival rates of bladder cancer patients with Ki-67 positive and PFN1 positive expression are shorter.
