Preoperative MRI accuracy after neoadjuvant chemoradiation for locally advanced rectal cancer.

Background And Aims: To evaluate the performance of magnetic resonance imaging (MRI) in restaging locally advanced rectal cancers (LARC) after neoadjuvant chemoradiotherapy (nCRT), with pathologic correlation.

Methods: 80 patients with LARC treated with neoadjuvant therapy, with restaging MRI and surgery, were enrolled and prospectively reviewed. The diagnostic accuracy of the restaging MRI was assessed for tumor (ymrT), nodal status (ymrN), circumferential resection margin (ymrCRM), extramural vascular invasion (ymrEMVI) and tumoral deposits (ymrN1c) by calculating the sensitivity (Se), specificity (Sp), negative predictive values (NPV) and positive predictive values (PPV).

MRI Evaluation of Complete and Near-Complete Response after Neoadjuvant Therapy in Patients with Locally Advanced Rectal Cancer.

To evaluate MRI performance in restaging locally advanced rectal cancers (LARC) after neoadjuvant chemoradiotherapy (nCRT) and interobserver agreement in identifying complete response (CR) and near-complete response (nCR). 40 patients with CR and nCR on restaging MRI, surgery and/or endoscopy were enrolled. Two radiologists independently scored the restaging MRI and reported the presence of split scar sign (SSS) and MRI tumor regression grade (mrTRG).

Paraneoplastic cerebellar degeneration associated with anti-Yo antibodies in an ovarian cancer case: A case report.

Paraneoplastic neurologic syndromes (PNS) are a rare heterogeneous group of disorders associated with malignancy that can result in significant functional impairment. One syndrome in particular, paraneoplastic cerebellar degeneration (PCD), may be severely disabling. PCD is a rare neurological syndrome, associated with active or subclinical cancer, characterized by acute or subacute onset cerebellar ataxia due to tumor-induced autoimmunity against cerebellar antigens.

Local staging of prostate cancer with multiparametric-MRI: accuracy and inter-reader agreement.

Background: The accuracy of prostate cancer local staging at the time of diagnosis directly influences patient prognosis and treatment.

Aim: To evaluate the diagnostic performance and interobserver variability of mp-MRI in local staging of prostate cancer, using the histopathologic findings at prostatectomy as the reference standard.

Methods: Fifty patients (mean age 64.

Interobserver agreement in prostate cancer detection using multiparametric MRI.

Purpose: The purpose of this prospective observational study was to evaluate the diagnostic performance of multiparametric (mp) magnetic resonance imaging (MRI) for prostate cancer detection and to assess the interobserver variability, using the Prostate Imaging Reporting and Data Systems (PI-RADS).

Methods: 50 patients (mean age 68.42±6.

1.5-Tesla Multiparametric-Magnetic Resonance Imaging for the detection of clinically significant prostate cancer.

Background And Aim: Multiparametric-magnetic resonance imaging (mp-MRI) is the main imaging modality used for prostate cancer detection. The aim of this study is to evaluate the diagnostic performance of mp-MRI at 1.5-Tesla (1.
