Abstract

This study intended to explore the relationship of PLK3 with prognosis in patients with colorectal cancer (CRC). PLK3 positivity was detected by immunohistochemistry in 160 patients with CRC receiving surgical resection. The median tumor PLK3-positive rate was 26.5%. Tumor PLK3-positive rate was related to increased lymph node stage (p = 0.002) and tumor-node-metastasis stage (p < 0.001) of CRC. Tumor PLK3-positive rate ≥30% was related to shortened disease-free survival (p = 0.009) and overall survival (p = 0.003); tumor PLK3-positive rate ≥50% showed a stronger correlation with them (both p = 0.001), which was validated by multivariate Cox regression analyses (both p < 0.05). Tumor PLK3-positive rate ≥50% relates to increased tumor stage and unfavorable survival in patients with CRC.
