Radiation therapy in the management of the inguinal region in penile cancer: What's the evidence?

Due to its rarity and lack of prospective studies, clinical evidence for the management of the inguinal lymphatic nodal basin with radiation therapy in penile cancer (PeCa) has been limited. In this report, we review the current literature and further investigated the landscape of radiation sensitivity in nodal metastases of PeCa utilizing our well-established genome-based radiosensitivity index (RSI) platform. We hypothesized that optimal therapeutic gain could be achieved in PeCa stratified by the combination of clinicopathological parameters, genomic heterogeneity, and RSI-based radiation dose prescription (RxRSI).

Characterization of urinary microbiome in patients with bladder cancer: Results from a single-institution, feasibility study.

Objectives: The human microbiome has been linked to the development of several malignancies, but there is scarcity of data on the microbiome of bladder cancer patients. In this study, we analyzed microbial composition and diversity among patients with and without bladder cancer.

Material And Methods: Samples were collected from 38 urothelial carcinoma (UC) patients and 10 noncancer controls from August 2018 to May 2019.

Novel Prognostic Models for Patients With Penile Carcinoma.

Although penile carcinoma is a rare malignancy, there is still an unmet need to identify prognostic factors associated with poor survival. In this study, we utilized demographic and clinical information to identify the most informative variables associated with overall survival in patients with penile cancer. From a full model including all covariates found to be statistically significant in univariable analyses, we identified a parsimonious reduced model containing tumor site (penis glans: hazard ratio [HR] = 0.

Meeting the challenge of the 2019 novel coronavirus disease in patients with cancer.

The alarming situation of the 2019 novel coronavirus disease (COVID‐19) is contrasted by the limited efforts to curb the spread and impact of the disease among patients with cancer. This commentary proposes a simple 5‐part strategy plus rapidly expanded use of telemedicine to anticipate and deal with COVID‐19 and, by extension, future epidemics in patients with cancer.

A phase II randomized clinical trial using aglycone isoflavones to treat patients with localized prostate cancer in the pre-surgical period prior to radical prostatectomy.

Prostate cancer (PCa) is the most common cancer in American men. Additionally, African American Men (AAM) are 60% more likely to be diagnosed with PCa and 2.4 times more likely to die from this disease compared to Caucasian men (CM).

Optimising the selection of candidates for neoadjuvant chemotherapy amongst patients with node-positive penile squamous cell carcinoma.

Objectives: To identify predictors of poor overall survival (OS) amongst patients with penile squamous cell carcinoma (pSCC) with clinical inguinal lymphadenopathy (cN+), in order to define the best candidates for neoadjuvant chemotherapy (NAC).

Patients And Methods: Using an international, multicentre database of 924 patients with pSCC, we identified 334 men who harboured cN+ with available clinical and follow-up data. Lymph node involvement was defined either by the presence of palpable inguinal node disease or by preoperative computed tomography (CT) assessment.

Systematic Review of the Therapeutic Efficacy of Bladder-preserving Treatments for Non-muscle-invasive Bladder Cancer Following Intravesical Bacillus Calmette-Guérin.

Context: There is a critical need for effective bladder-sparing therapies for bacillus Calmette-Guérin (BCG)-unresponsive non-muscle-invasive bladder cancer (NMIBC). Owing to the current lack of effective agents that can be used as a control, the US Food and Drug Administration began to accept single-arm trials for patients with carcinoma in situ (CIS), using complete response rate (CRR) and duration of response as the primary endpoints to support marketing applications. Despite the ensuing growth of clinical trials in this space, no consensus exists on a clinically relevant benchmark for CRR.

Bladder Cancer, Version 3.2020, NCCN Clinical Practice Guidelines in Oncology.

This selection from the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Bladder Cancer focuses on the clinical presentation and workup of suspected bladder cancer, treatment of non-muscle-invasive urothelial bladder cancer, and treatment of metastatic urothelial bladder cancer because important updates have recently been made to these sections. Some important updates include recommendations for optimal treatment of non-muscle-invasive bladder cancer in the event of a bacillus Calmette-Guérin (BCG) shortage and details about biomarker testing for advanced or metastatic disease. The systemic therapy recommendations for second-line or subsequent therapies have also been revised.

Urinary leak following partial nephrectomy: a contemporary review of 975 cases.

Introduction: To describe the incidence, contemporary management, risk factors and outcomes of urinary leak following open and robotic partial nephrectomy at a tertiary care, comprehensive cancer center.

Materials And Methods: We reviewed 975 patients who underwent partial nephrectomy at Moffitt Cancer Center from January 2009 to May 2017. Patient demographic, perioperative and follow up data was recorded and compared stratified for postoperative urine leak.

Impact of sex on response to neoadjuvant chemotherapy in patients with bladder cancer.

Objective: To assess the effect of patient's sex on response to neoadjuvant chemotherapy (NAC) in patients with clinically nonmetastatic muscle-invasive bladder cancer (MIBC).

Methods: Complete pathologic response, defined as ypT0N0 at radical cystectomy, and downstaging were evaluated using sex-adjusted univariable and multivariable logistic regression modeling. We used interaction terms to account for age of menopause and smoking status.

Electrochemical Synthesis of Biaryls via Oxidative Intramolecular Coupling of Tetra(hetero)arylborates.

We report herein versatile, transition metal-free and additive-free (hetero)aryl-aryl coupling reactions promoted by the oxidative electrocoupling of unsymmetrical tetra(hetero)arylborates (TABs) prepared from ligand-exchange reactions on potassium trifluoroarylborates. Exploiting the power of electrochemical oxidations, this method complements the existing organoboron toolbox. We demonstrate the broad scope, scalability, and robustness of this unconventional catalyst-free transformation, leading to functionalized biaryls and ultimately furnishing drug-like small molecules, as well as late stage derivatization of natural compounds.

Systematic Review and Meta-Analysis-Is there a Benefit in Using Neoadjuvant Systemic Chemotherapy for Locally Advanced Penile Squamous Cell Carcinoma?

Purpose: Neoadjuvant chemotherapy is a recommended treatment for patients with penile cancer with bulky inguinal lymphadenopathy or unresectable primary tumors, although there is no evidence of its benefit from randomized trials.

Materials And Methods: We conducted a systematic search in Embase® and MEDLINE® for studies reporting on patients who received preoperative neoadjuvant chemotherapy for locally advanced penile squamous cell carcinoma. Objective response rate, pathological complete response, grade 3 or greater toxicity and overall mortality were evaluated in terms of neoadjuvant chemotherapy type, which was dichotomized as nontaxane-platinum and taxane-platinum regimens.

Cobalt-Catalyzed Cross-Coupling of Functionalized Alkylzinc Reagents with (Hetero)Aryl Halides.

A combination of 10 % CoCl and 20 % 2,2'-bipyridine ligands enables cross-coupling of functionalized primary and secondary alkylzinc reagents with various (hetero)aryl halides. Couplings with 1,3- and 1,4-substituted cycloalkylzinc reagents proceeded diastereoselectively leading to functionalized heterocycles with high diastereoselectivities of up to 98:2. Furthermore, alkynyl bromides react with primary and secondary alkylzinc reagents providing the alkylated alkynes.

Efficacy of Preoperative Chemotherapy for High Risk Upper Tract Urothelial Carcinoma.

Purpose: The impact of preoperative chemotherapy in patients with upper urinary tract urothelial carcinoma remains poorly investigated. We assessed the rates of pathological complete response (pT0N0/X) and downstaging (pT1N0/X or less) at radical nephroureterectomy after preoperative chemotherapy and evaluated their impact on survival.

Materials And Methods: This was an international observational study of patients who underwent preoperative chemotherapy and radical nephroureterectomy for high risk upper tract urothelial carcinoma between 2005 and 2017.

Extramammary Paget's disease: what do we know and how do we treat?

Introduction: Extramammary Paget's disease (EMPD) is a rare and complex condition, for which no established guidelines exist regarding diagnosis and management. There have been recent improvements in the diagnosis and management in EMPD, largely due to an enhanced understanding of its underlying pathogenesis.

Materials And Methods: A literature search on PubMed including articles that describe pathogenesis, clinical diagnosis, treatment modalities, and future treatment were selected and included to build this review.

The prognostic value of the neutrophil-to-lymphocyte ratio in patients with muscle-invasive bladder cancer treated with neoadjuvant chemotherapy and radical cystectomy.

Introduction: The neutrophil-to-lymphocyte ratio (NLR) is an attractive marker because it is derived from routine bloodwork. NLR has shown promise as a prognostic factor in muscle invasive bladder cancer (MIBC) but its value in patients receiving neoadjuvant chemotherapy (NAC) before radical cystectomy (RC) is not yet established. Since NLR is related to an oncogenic environment and poor antitumor host response, we hypothesized that a high NLR would be associated with a poor response to NAC and would remain a poor prognostic indicator in patients receiving NAC.

Prognostic value of PD-L1 expression for surgically treated localized renal cell carcinoma: implications for risk stratification and adjuvant therapies.

Background: We aimed to evaluate the prognostic role of programmed-death receptor ligand (PD-L1) in a multinational cohort of patients with localized renal cell carcinoma (RCC).

Methods: Formalin-fixed paraffin-embedded blocks of 1017 patients from the Latin American Renal Cancer Group were analyzed. Tissue microarrays were immunostained for PD-L1 using a commercially available monoclonal antibody.

Prognosis of the 8th TNM Staging System for Penile Cancer and Refinement of Prognostication by Incorporating High Risk Human Papillomavirus Status.

Purpose: We evaluated the prognostic value of the 8th TNM staging system and assessed a modified N stage incorporating high risk human papillomavirus status in a multicenter cohort.

Materials And Methods: Included in analysis were 292 patients with M0 penile squamous cell carcinoma from a total of 6 referral centers. High risk human papillomavirus status was examined.

Diagnostic Value of F-fluorodeoxyglucose Positron Emission Tomography with Computed Tomography for Lymph Node Staging in Patients with Upper Tract Urothelial Carcinoma.

Background: Presence of lymph node metastases (LNM) is an important prognostic factor for cancer-specific survival (CSS) in patients with upper tract urothelial carcinoma (UTUC). In various neoplasms, F-fluorodeoxyglucose positron emission tomography with computed tomography (FDG-PET/CT) is an established modality for preoperative lymph node (LN) staging. In UTUC, the diagnostic value of FDG-PET/CT for LN staging is unknown.
