Core Tip

Core Tip: Marker Ki-67 (MKI67) has been established to correlate with the proliferation and metastasis of various malignant tumor cells, including those implicated in prostate cancer (PCa). Our objective is to validate the connection between MKI67 and the diagnosis as well as prognosis of PCa, by deploying two distinct patient cohorts from bioinformatics and clinical data. Within the bioinformatics data cohort, comprising 496 PCa tissue samples juxtaposed with 152 normal controls, we ascertained that MKI67 possesses a strong diagnostic ability for PCa along with a moderate prognostic prediction potential. Similarly, through our retrospective analysis of clinical data from 271 PCa patients, we confirmed the potent diagnostic capacity of MKI67 for PCa and its capability to predict prognosis to a certain extent.
