PURPOSE: To determine the accuracy of in-bore transperineal 3-Tesla (T) magnetic resonance (MR) imaging-guided prostate biopsies for predicting final Gleason grades in patients who subsequently underwent radical prostatectomy (RP). METHODS: A retrospective review of men who underwent transperineal MR imaging-guided prostate biopsy (tpMRGB) with subsequent radical prostatectomy within 1 year was conducted from 2010 to 2015. All patients underwent a baseline 3-T multiparametric MRI (mpMRI) with endorectal coil and were selected for biopsy based on MR findings of a suspicious prostate lesion and high degree of clinical suspicion for cancer...

REVIEW
Courtney C Moreno, Patrick S Sullivan, Pardeep K Mittal
Magnetic resonance imaging (MRI) plays an important role in the staging and restaging of rectal cancer. Multiplanar high-resolution (≤3-mm section thickness) T2-weighted images are the primary sequences used for rectal cancer staging. No preprocedural bowel cleansing regimen, intravenous contrast material, nor endorectal coil is necessary. MRI is highly accurate for differentiating T1-T2 disease from T3 and T4 disease, an important distinction as patients with T3 and T4 tumors typically undergo preoperative neoadjuvant chemoradiation before resection...

INTRODUCTION: Gastrointestinal stromal tumors (GIST) are tumors of mesenchymal origin commonly detected in stomach and small bowel. GIST arising primarily from the anal canal is extremely rare. Due to the malignant potential, these tumors are treated with radical surgery like abdominoperineal resection. But with the advent of imatinib therapy and a better understanding of the tumor biology, some cases have been successfully treated with wide local excision. PRESENTATION OF CASE: We describe a case of a 70-year-old lady presenting with a 2cm mass in the anal canal...

Prostate cancer is the first cancer and the second cause of cancer death in men in France. It is now a major public health issue, particularly given the increase of life expectancy. If screening is based on blood PSA and clinical examination (DRE), diagnosis requires the histological analysis of prostate samples. In current clinical routine, these biopsies are performed by endorectal through ultrasound guidance. In most cases, the cancer is not visible in the ultrasound image and the latter is used to make a dozen samples (or core), distributed as best as possible in the prostate...

Prostate volume in multiparametric MRI (mpMRI) is of clinical importance. For 3-Tesla mpMRI without endorectal coil, there is no distinctive standard for volume calculation. We tested the accuracy of the ellipsoid formula with planimetric volume measurements as reference and investigated the correlation of gland volume and cancer detection rate on MRI/ultrasound (MRI/US) fusion-guided biopsy. One hundred forty-three patients with findings on 3-Tesla mpMRI suspicious of cancer and subsequent MRI/US fusion-guided targeted biopsy and additional systematic biopsy were analyzed...

We present the case of a patient in whom consecutive imaging assessment and surgery demonstrated the obvious progression of colorectal endometriosis under continuous medical therapy. A 26-year-old nullipara presented with secondary dysmenorrhea, deep dyspareunia, diarrhea, and constipation during menstruation. Magnetic resonance imaging (MRI) assessment revealed 2 right ovarian endometriomas, but no deep endometriosis lesion. Intraoperatively, we found a 2-cm length of thickened and congestive area of sigmoid colon, along with small superficial lesions arising in the small bowel and appendix...

OBJECTIVE: Obesity is a major health concern and risk factor for colorectal cancer that may also impact cancer treatment and outcomes. Rectal cancer response to chemoradiotherapy (CXRT) is associated with long-term survival and sphincter preservation. The purpose of this study was to evaluate the impact of obesity on treatment outcomes after neoadjuvant CXRT for rectal cancer. METHODS: A retrospective cohort study of patients diagnosed (1993 to 2010) with cT3-4 or cN+ (by endorectal ultrasound, computed tomography, or magnetic resonance imaging) rectal carcinoma and treated with CXRT and total mesorectal excision was performed...

PURPOSE: Focal therapy in low-risk prostate cancer may provide the best balance between cancer control and quality of life preservation. As a minimally invasive approach performed under TRUS guidance, brachytherapy is an appealing framework for focal therapy. However, the contrast in TRUS images is generally insufficient to distinguish the target lesion from normal prostate tissue. MRI usually offers a much better contrast between the lesion and surrounding tissues. Registration between TRUS and MRI may therefore significantly improve lesion targeting capability in focal prostate brachytherapy...

Background. Rectal tumour management depends highly on locoregional extension. Rectal endoscopic ultrasound (ERUS) is a good alternative to computed tomography and magnetic resonance imaging. However, in Hungary only a small amount of rectal tumours is examined with ERUS. Methods. Our retrospective study (2006-2012) evaluates the diagnostic accuracy of ERUS and compares the results, the first data from Central Europe, with those from Western Europe. The effect of neoadjuvant therapy, rectal probe type, and investigator's experience were also assessed...
