To evaluate the performance of the Vesical Imaging-Reporting and Data System (VIRADS) in differentiating muscle-invasive and non-muscle-invasive bladder cancer and whether this reporting system improves inter-reader agreement.

To investigate whether presence of multifocality on multi-parametric magnetic resonance imaging (mpMRI) would increase the likelihood of detecting clinically-significant prostate cancer (csPCa) in a PI-RADS 4 lesion.

At the heart of selecting an optimal management strategy for men with prostate cancer is accurately determining a given patient's clinical stage and extent of disease. Molecular imaging with PET using properly selected radiotracers offers the opportunity for improved contrast resolution over conventional imaging and thus increased sensativity for detecting sites of disease.

Seminoma accounts for 30-50% of testicular germ cell tumors (TGCT)-the most common solid malignancy in men aged 15-35 years. The American Joint Committee on Cancer (AJCC) 8th edition (2018) created the subclassifications pT1a (tumor size < 3 cm) and pT1b (≥ 3 cm), despite not being universally recognized.

Indications for restaging transurethral resection of the bladder tumor (reTURBT) in patients with non-muscle-invasive bladder cancer (NMIBC) remain controversial. This study was aimed at evaluation of clinical value and safety of reTURBT in different clinical indications.

Wallis et al (JAMA 2017) demonstrated use of antithrombotic medications (ATMs) is associated with increased prevalence of hematuria-related complications and subsequent bladder cancer diagnosis within 6 months.

Stage III renal cell carcinoma (RCC) encompasses both lymph node-positive (pT1-3N1M0) and lymph node-negative (pT3N0M0) disease. However, prior institutional studies have indicated that among patients with stage III disease, those with lymph node disease have worse oncologic outcomes and experience survival that is similar to that of patients with American Joint Committee on Cancer (AJCC) stage IV disease.

The Society of Nuclear Medicine and Molecular Imaging (SNMMI) provides appropriate use criteria (AUC) for prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) which include guidance on imaging in newly diagnosed prostate cancer and in patients with biochemically recurrent (BCR) disease.

Multiparametric magnetic resonance imaging (mp-MRI) and MRI/Ultrasound (US) fusion-guided biopsy are relatively new techniques for improved detection, staging, and active surveillance of prostate cancer (PCa).

To evaluate the incremental value of magnetic resonance imaging (MRI), compared to clinical examination, for penile cancer (PC) local staging.

Twenty-five consecutive patients with histologically proven PC were evaluated prospectively.

Magnetic resonance imaging (MRI) is recommended in patients with upper tract urothelial carcinoma (UTUC) only when computed tomography (CT) is contraindicated. However, CT does not allow distinguishing ureter wall layers, making impossible to assess muscle invasion, a factor contributing to differentiate high- from low-risk UTUCs, which require different therapeutic approaches.

The majority of RCCs occur within the 7th decade of life, uncommonly arising in adults ≤46years. We reviewed the clinicopathologic features of early-onset renal cell carcinoma (RCC) and evaluated the role of immunohistochemistry (IHC) in potentially identifying diagnoses of newly recognized RCC subtypes that may have been previously misclassified.

The diagnostic accuracy of computed tomography urography for upper tract urothelial carcinoma is high; however, difficulties are associated with precisely assessing the T stage. Preoperative tumor staging has an impact on treatment options for upper tract urothelial carcinoma.

The current study was conducted to assess the impact of lymphovascular invasion on the survival of patients with urothelial carcinoma of the renal pelvis.

Patients with urothelial carcinoma of the renal pelvis who underwent radical nephroureterectomy from 2010 through 2015 were identified in the National Cancer Data Base.

BACKGROUND - The current study was conducted to evaluate the performance of magnetic resonance (MR)-ultrasound-guided fusion biopsy in diagnosing clinically significant prostate cancer (csCaP).

METHODS - A total of 1042 men underwent multiparametric MR imaging (mpMRI) and fusion biopsy consecutively in a prospective trial (2009-2014).

The purpose of this article is to review imaging modalities used in local staging of bladder urothelial carcinoma.

Urothelial carcinoma is the most common histologic subtype of bladder cancer, and accurate local staging of this tumor is crucial for management.

To review bladder specimens referred to our facility for secondary review to determine the frequency and degree of changes in pathological diagnoses, which could affect patient care.

A retrospective review of 246 bladder specimens sent to our pathology department for second opinion pathological review was performed.

Clear cell renal cell carcinoma (ccRCC) is a highly prevalent subtype of malignant renal tumor, but unfortunately, the survival rate remains unsatisfactory. The aim of the present study is to explore genomic features that are correlated with cancer stage, allowing for the identification of subgroups of ccRCC patients with high risk of unfavorable outcomes and enabling prompt intervention and treatment.

Bladder cancer (BC) is the most common cancer of the urinary tract in the United States. Imaging plays a significant role in the management of patients with BC, including the locoregional staging and evaluation for distant metastatic disease, which cannot be assessed at the time of cystoscopy and biopsy/resection.

Nationwide cancer registries such as the National Cancer Database and Surveillance, Epidemiology, and End Results rely on accurate data from tumor registries to formulate hypotheses and report outcomes and treatment patterns.

A scoring system focusing on the risk of muscle layer invasion by Bladder cancer (BCa) has been released, Vesical Imaging - Radiological and Data System (VI-RADS), with a growing interest in evaluating its diagnostic accuracy.
