Detailed Description
Investigators plan to develop a diagnostic and prognostic evaluation model for prostate cancer according to analyze the abnormal echo of prostate ultrasound images by radiomics. The model was used to perform ultrasound radiomics fusion prostate biopsy, and the accuracy was compared with that of MRI cognitive fusion biopsy.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Ultrasound fusion targeted biopsy Prostate ultrasound had abnormal echo and radiomics analysis showed high scores |
|
| mpMRI cognitive fusion targeted biopsy PI-RADS score ≥ 3 |
Outcome Measures
Primary Outcome Measures
- Positive rate of ultrasound radiomics fusion targeted biopsy [Up to seventh day when the pathological results were obtained after the targeted biopsy]
Positive rate of ultrasound radiomics fusion targeted biopsy
- Positive rate of mpMRI cognitive fusion targeted biopsy [Up to seventh day when the pathological results were obtained after the targeted biopsy]
Positive rate of mpMRI cognitive fusion targeted biopsy
- Ultrasound radiomics parameters [The 30min following the transrectal ultrasonography]
The ultrasound images are obtained by transrectal ultrasound while prostate biopsy. Then investigators use 3D-Slicer software to draw the area of interest (ROI). "Pyradiomics" library will be used to extract the radiomics features.
Secondary Outcome Measures
- Gleason's score of positive tissue [Up to seventh day when the pathological results were obtained after the targeted biopsy]
Gleason's score of positive tissue from targeted prostate biopsy. Prostate cancer was graded by Gleason score (GS) ranging from 6 to 10. Tumors of GS 6 (3 + 3) are considered low grade (LG), while GS ≥7 are high grade (HG).
- PI-RADS score [Within one month prior to prostate biopsy.]
Prostate Imaging Reporting and Data System (PI-RADS) score was obtained according to multiparametric magnetic resonance imaging. PI-RADS is used to standardize interpretation of prostate MRI. Each lesion is assigned a score from 1 to 5 indicating the likelihood of clinically significant cancer. PI-RADS 1: clinically significant cancer is highly unlikely to be present; PI-RADS 2: clinically significant cancer is unlikely to be present; PI-RADS 3: the presence of clinically significant cancer is equivocal; PI-RADS 4: clinically significant cancer is likely to be present; PI-RADS 5: clinically significant cancer is highly likely to be present.
- tPSA and fPSA [Within one month prior to prostate biopsy.]
tPSA means total Prostate-Specific Antigen (PSA), and fPSA means free Prostate-Specific Antigen. If the tPSA results are in the borderline range (4 to 10), fPSA can be useful in helping distinguish between prostate cancer or benign prostatic hyperplasia (BPH).
- Prostate tumor capsular invasion and positive surgical margin [Up to seventh day after radical prostatectomy.]
The pathological specimens of the surgically resected prostate were used to determine whether there were capsular invasion or positive surgical margins. In the pathological sections, tumor cells could be identified by staining and microscopic observation at the tissue cauterization margin and capsule, and then capsular invasion or positive surgical margins could be identified.
- Incidence of complications [Up to the first month after the targeted biopsy]
Incidence of complications associated with prostate biopsy
