0-Tesla magnetic resonance imaging to predict the absence of side-specific extracapsular extension
of prostate cancer.
Wide neurovascular bundle excision was performed for cases of ipsilateral high-volume and/or high-grade disease with suspected extracapsular extension
based on clinical stage, visual inspection, tissue reaction, or MRI findings.
However, only a few studies have kept watch on preoperative evaluation of capsular invasion (CI) or extracapsular extension
(ECE) and cervical lymph node metastasis using preoperative ultrasonography.
those with bulky regional disease, extracapsular extension
, and multiple metastatic lymph nodes) and was still performed.
Exclusion criteria included 3 or more H&E-positive SLNs, matted LNs or gross extracapsular extension
(ECE), CKIHC-detected SLN metastases, and mastectomy.
19 mm lesion (PIRADS 4) with no extracapsular extension
(ECE) was identified in the left base of the peripheral zone.
Axial high resolution T2w images [A, B] showing area of decreased signal intensity in Right posterolateral peripheral zone with extracapsular extension
The cervical lymphadenectomy revealed one right cervical lymph node with metastatic squamous cell carcinoma and extracapsular extension
In this study, the relationship between the presence of the tertiary Gleason pattern and age, the preoperative PSA, clinical stage, biopsy scores, postoperative pathology results (Gleason score, pathological stage, extracapsular extension
, seminal vesicle invasion, lymph node invasion, surgical margin positivity), and postoperative PSA levels were analyzed.
It had a thin capsule with no extracapsular extension
The selection of therapy is especially important when there is a risk for stageT3 disease with extraglandular extension (EGE) (4) In these cases, MR imaging with an endorectal coil can achieve positive predictive values between 85% and 97% for extracapsular extension
(ECE) and seminal vesicle invasion (SVI), respectively.
Also, the presence of extracapsular extension
, shown to predict poor outcome in HPV-negative patients, appears to have little impact in those who are HPV positive.
