Abstract
AIM: To investigate the relationship between the blood flow dynamics detected by transrectal ultrasound (TRUS) and the pathological stage of rectal cancer.
METHODS: A total of 240 patients with pathologically confirmed rectal cancer who underwent TRUS before operation were included. The hemodynamic parameters (PI, PSV, RI, and EDV) of the tumor were routinely detected. According to the pathological stage, the parameters were analyzed retrospectively and compared.
RESULTS: PI and RI decreased with the increase of the pathological stage, and EDV and PSV increased with the increase of the pathological stage. PI and RI were negatively correlated with pathology (r = -0.680, -0.470; P = 0.000, 0.000). PSV and EDV were positively correlated with pathology (r = 0.200, 0.289; P = 0.000, 0.000).
CONCLUSION: Detection of conventional arterial hemodynamic parameters (PI, PSV, RI, and EDV) can provide important and valuable information for clinical staging of rectal cancer.
