Abstract:
Objective To systematically analyze and assess the overall value of transrectal shear wave elastograpy in diagnosis of prostate cancer (PCa) using Meta-analysis.Methods Relevant Chinese and foreign papers diagnosing PCa with transrectal shear wave elastograpy published before December 2016 were searched.The references were evaluated and screened according to the criteria of diagnostic research.The selected references were analyzed by Meta-Disc 1.4 and Stata 12.0 statistical software.Results Eight articles were included in the present Meta-analysis.Five of these literatures were about transrectal shear wave elastograpy in diagnosis of PCa,the summarized sensitivity (SEN) and summarized specificity (SPE) in diagnosis of PCa were 0.80 (95％CI [0.75,0.84]) and 0.75 (95％CI [0.71,0.79]),respectively;the positive likelihood ratios (PLR) and negative likelihood ratios (NLR) were 3.60 (95 ％ CI [2.57,5.05]) and 0.17 (95 ％ CI[0.08,0.37]),respectively;the area under SROC curves was 0.895.Five of these literatures were about transrectal shear wave elastograpy supplemental prostatic biopsy in diagnosis of PCa,the summarized SEN and SPE were 0.86 (95％ CI [0.83,0.88]) and 0.84 (95％CI [0.82,0.85]) respectively;the PLR and NLR were 5.81 (95％CI [3.07,10.99]) and 0.14 (95％CI [0.04,0.49]) respectively;the area under SROC curves were 0.924.Conclusion Transrectal shear wave elastograpy has better clinical value in detection of PCa and can be used to supplemental prostatic biopsy.
