Management options for node-positive muscle-invasive bladder cancer.

Localized node-positive bladder cancer is characterized by a high degree of heterogeneity, leading to significant variability in overall survival outcomes among affected individuals. The absence of standardized treatment guidelines presents a critical challenge in managing these patients effectively. This comprehensive review article delves into the pathophysiology, clinical significance, and management of node-positive bladder cancer.

Systemic Anticancer Therapy and Thromboembolic Outcomes in Hospitalized Patients With Cancer and COVID-19.

Importance: Systematic data on the association between anticancer therapies and thromboembolic events (TEEs) in patients with COVID-19 are lacking.

Objective: To assess the association between anticancer therapy exposure within 3 months prior to COVID-19 and TEEs following COVID-19 diagnosis in patients with cancer.

Design, Setting, And Participants: This registry-based retrospective cohort study included patients who were hospitalized and had active cancer and laboratory-confirmed SARS-CoV-2 infection.

A rare cutaneous manifestation of immune checkpoint inhibitor therapy.

Leukocytoclastic vasculitis can be an uncommon and/or underreported adverse event of immune checkpoint inhibitor therapy, an established cancer treatment option. Differentiation among other cutaneous manifestations of adverse medication reactions-such as Stevens-Johnson syndrome, erythema multiforme, and drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome-is crucial for guiding management.

Demographics, Outcomes, and Risk Factors for Patients with Sarcoma and COVID-19: A CCC19-Registry Based Retrospective Cohort Study.

Background: Patients with sarcoma often require individualized treatment strategies and are likely to receive aggressive immunosuppressive therapies, which may place them at higher risk for severe COVID-19. We aimed to describe demographics, risk factors, and outcomes for patients with sarcoma and COVID-19.

Methods: We performed a retrospective cohort study of patients with sarcoma and COVID-19 reported to the COVID-19 and Cancer Consortium (CCC19) registry (NCT04354701) from 17 March 2020 to 30 September 2021.

Geography Should Not Be an "Oncologic Destiny" for Urothelial Cancer: Improving Access to Care by Removing Local, Regional, and International Barriers.

Urothelial cancer care is particularly susceptible to geographical health disparity given its complex nature, requiring access to several specialists such as a urologist, a medical oncologist, a radiation oncologist, a surgical oncologist, and multidisciplinary care teams. Furthermore, other barriers to care access in underserved areas include travel burden, longer wait times, late-stage disease at the time of diagnosis, cost, type of treatment, less enrollment in clinical trials, lack of follow-up among cancer survivors, and less research funding in this area. Here, we discuss the impact of geographical location on access to urothelial cancer care, management decisions, and outcomes and we reflect on how to address geographical disparities in care delivery.

DRESS is a Mess: A Case of Cross Reactivity Between Lacosamide and Lamotrigine.

Drug reaction with eosinophilia with systemic symptoms (DRESS) syndrome is a rare drug reaction often presenting with both cutaneous manifestations and potentially life-threatening internal organ involvement. The precise incidence of DRESS is still unclear as it is easily missed due to its highly variable clinical presentation. However, with an expected mortality rate of approximately 10 percent, it is important for clinicians to be familiar with pharmacologic etiologies commonly implicated in the pathogenesis.

A Case of Cefepime-Induced Neurotoxicity: Renal Function Missing in Action.

Cefepime is a renally excreted, fourth-generation cephalosporin used in the treatment of severe abdominal, skin, soft tissue, and urinary tract infections due to its broad-spectrum coverage. Cefepime-induced neurotoxicity is a rare but serious side effect that has increased in recent years likely due to increased antibiotic use, increased drug resistance, and increased symptom recognition. While decreased glomerular filtration rate is an important risk factor for developing elevated serum cefepime levels, recent literature has suggested that a significant proportion of patients with normal renal function can also develop neurotoxicity from cefepime.

Approach to critical illness myopathy and polyneuropathy in the older SARS-CoV-2 patients.

One of the major concerns of the health care community and the public surrounding the SARS-CoV-2 pandemic is the availability and use of ventilators. Unprecedented surges of patients presented to intensive care units across the country, with older adults making up a large proportion of the patient population. This paper illustrates contemporary approaches to critical illness myopathy (CIM), critical illness polyneuropathy (CIP), and critical illness polyneuromyopathy (CIPNM) in older patients, including incidence, risk factors, mechanisms for pathology, diagnosis, contemporary treatment approaches, and outcomes.

Higher serum PD-L1 level predicts increased overall survival with lapatinib versus trastuzumab in the CCTG MA.31 phase 3 trial.

Background: The purpose of this retrospective biomarker study of the Canadian Cancer Trials Group (CCTG) MA.31 randomized phase 3 trial (lapatinib vs trastuzumab) of HER2-positive metastatic breast cancer (MBC) was to evaluate the prognostic and predictive biomarker utility of pretreatment serum programmed death ligand 1 (PD-L1) levels.

Methods: CCTG MA.

Immune mediated necrotizing myopathy: A rare complication of statin therapy.

Immune mediated necrotizing myopathy (IMNM) is part of the inflammatory myopathies group of diseases and presents with muscle weakness, myalgias and elevated serum creatine phosphokinase (CPK). Statin-induced IMNM is a rare complication. We present a patient with IMNM secondary to simvastatin use.

COVID-19: Catastrophic Cause of Acute Lung Injury.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak that began in 2019 and spread rapidly across the globe has been observed to cause acute lung injury and multiorgan system failure. While common symptoms are flu-like, this population has been observed to decompensate at an alarmingly rapid rate to severe hypoxia. SARS-CoV-2 infects host cells by targeting the angiotensin-converting enzyme 2 (ACE2) receptor, which is present on endothelial cells in the lung, heart, kidney, and gastrointestinal tissue.

Metastasis of Ewing Sarcoma to the Pancreas: Case Report and Literature Review.

Ewing sarcoma (ES) is a highly aggressive malignant bone cancer. ES is part of the Ewing sarcoma family of tumors (ESFT), which express characteristic t(11;22) translocation as well as higher levels of CD99. Given that metastasis and tumor burden are significant prognostic factors in patient's response to treatment, prompt diagnosis is needed to effectively treat ESFT patients.

Collagen fragments quantified in serum as measures of desmoplasia associate with survival outcome in patients with advanced pancreatic cancer.

Pancreatic ductal adenocarcinoma (PDAC) patients have poor prognosis and poor response to treatment. This is largely due to PDAC being associated with a dense and active stroma and tumor fibrosis (desmoplasia). Desmoplasia is characterized by excessive degradation and formation of the extracellular matrix (ECM) generating collagen fragments that are released into circulation.

A Case of Confirmed Ceftriaxone-induced Immune Thrombocytopenia.

Drug-induced immune thrombocytopenia (DITP) is a rare, but potentially fatal cause of isolated thrombocytopenia. DITP is thought to occur when drug-dependent antibodies bind to the platelet membrane glycoproteins to activate platelet consumption signaling. Common implicated drugs include quinine/quinidine, penicillamines, valproic acid and cotrimoxazole.

High turnover of extracellular matrix reflected by specific protein fragments measured in serum is associated with poor outcomes in two metastatic breast cancer cohorts.

Increased extracellular matrix (ECM) formation and matrix metalloprotease (MMP)-mediated ECM degradation are parts of tumorgenesis and generates collagen fragments that are released into circulation. We evaluated the association of specific collagen fragments measured in serum with outcomes in two independent metastatic breast cancer (MBC) cohorts. ELISAs were used to measure C1M (MMP-generated type I collagen fragment), C3M (MMP-generated type III collagen fragment), C4M (MMP-generated type IV collagen fragment), and PRO-C3 (pro-peptide of type III collagen) in pretreatment serum from a phase 3 randomized clinical trial of second-line hormone therapy (HR+, n = 148), and a first-line trastuzumab-treated cohort (HER2+, n = 55).
