Transrectal Elastosonography
Diagnostic accuracy studies that compared
transrectal elastosonography with one of two reference standards (transrectal ultrasound-guided prostate
biopsy or
histopathology of radical prostatectomy specimen) in men with suspected prostate
cancer were eligible for inclusion.
Transrectal Elastosonography (TRES) is an emerging technique that would map the relative tissue stiffness of prostate . This can differentiate
cancer foci from the benign
tissues within prostate. While, using
histopathology of the novel prostatectomy specimens as reference standard, the sensitivity of TRES ranged between 0.71-0.82 and therefore the specificity ranged between 0.60-0.95. With grey scale TRUS, localization of the
cancer foci in prostate may be a challenge. Indicative exactness considers that contrasted
transrectal elastosonography and one of two reference norms (transrectal ultrasound-guided prostate
biopsy or
histopathology of radical prostatectomy example) in men with suspected prostate
malignancy were qualified for consideration. Included investigations were distributed from 2002 up to 2010. Half of the included examinations were led in Europe, with the rest in Japan or the USA. Ten examinations utilized transrectal ultrasound-guided
biopsy as the reference standard; different preliminaries utilized
histopathology of radical prostatectomy example. Be that as it may, seven investigations were excluded from the meta-examination on the grounds that the reference standard didn't adjust to current practice (least ten transrectal ultrasound-guided biopsies).
