Background: Limited information is available for patients with breast cancer (BC) and coronavirus disease 2019 (COVID-19), especially among underrepresented racial/ethnic populations., Methods: This is a COVID-19 and Cancer Consortium (CCC19) registry-based retrospective cohort study of females with active or history of BC and laboratory-confirmed severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection diagnosed between March 2020 and June 2021 in the US. Primary outcome was COVID-19 severity measured on a five-level ordinal scale, including none of the following complications, hospitalization, intensive care unit admission, mechanical ventilation, and all-cause mortality. Multivariable ordinal logistic regression model identified characteristics associated with COVID-19 severity., Results: 1383 female patient records with BC and COVID-19 were included in the analysis, the median age was 61 years, and median follow-up was 90 days. Multivariable analysis revealed higher odds of COVID-19 severity for older age (aOR per decade, 1.48 [95% CI, 1.32-1.67]); Black patients (aOR 1.74; 95 CI 1.24-2.45), Asian Americans and Pacific Islander patients (aOR 3.40; 95 CI 1.70-6.79) and Other (aOR 2.97; 95 CI 1.71-5.17) racial/ethnic groups; worse ECOG performance status (ECOG PS ≥2: aOR, 7.78 [95% CI, 4.83-12.5]); pre-existing cardiovascular (aOR, 2.26 [95% CI, 1.63-3.15])/pulmonary comorbidities (aOR, 1.65 [95% CI, 1.20-2.29]); diabetes mellitus (aOR, 2.25 [95% CI, 1.66-3.04]); and active and progressing cancer (aOR, 12.5 [95% CI, 6.89-22.6]). Hispanic ethnicity, timing, and type of anti-cancer therapy modalities were not significantly associated with worse COVID-19 outcomes. The total all-cause mortality and hospitalization rate for the entire cohort was 9% and 37%, respectively however, it varied according to the BC disease status., Conclusions: Using one of the largest registries on cancer and COVID-19, we identified patient and BC-related factors associated with worse COVID-19 outcomes. After adjusting for baseline characteristics, underrepresented racial/ethnic patients experienced worse outcomes compared to non-Hispanic White patients., Funding: This study was partly supported by National Cancer Institute grant number P30 CA068485 to Tianyi Sun, Sanjay Mishra, Benjamin French, Jeremy L Warner; P30-CA046592 to Christopher R Friese; P30 CA023100 for Rana R McKay; P30-CA054174 for Pankil K Shah and Dimpy P Shah; KL2 TR002646 for Pankil Shah and the American Cancer Society and Hope Foundation for Cancer Research (MRSG-16-152-01-CCE) and P30-CA054174 for Dimpy P Shah.

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., Competing Interests: To the best of our knowledge, no conflict of interest, financial, or otherwise exists among all authors., (© 2023 The Authors.

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. Demographics, sarcoma histologic type, treatments, and COVID-19 outcomes were analyzed., Results: of 281 patients, 49% ( n = 139) were hospitalized, 33% ( n = 93) received supplemental oxygen, 11% ( n = 31) were admitted to the ICU, and 6% ( n = 16) received mechanical ventilation. A total of 23 (8%) died within 30 days of COVID-19 diagnosis and 44 (16%) died overall at the time of analysis. When evaluated by sarcoma subtype, patients with bone sarcoma and COVID-19 had a higher mortality rate than patients from a matched SEER cohort (13.5% vs 4.4%). Older age, poor performance status, recent systemic anti-cancer therapy, and lung metastases all contributed to higher COVID-19 severity., Conclusions: Patients with sarcoma have high rates of severe COVID-19 and those with bone sarcoma may have the greatest risk of death.

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.

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. We present a case of DRESS syndrome attributed to cross-reactivity between two commonly used anticonvulsants- lacosamide and lamotrigine., (Copyright© South Dakota State Medical Association.)

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.31 accrued 652 HER2-positive patients; 387 had serum available (185 in the trastuzumab arm and 202 in the lapatinib arm). The Ella immunoassay platform (ProteinSimple, San Jose, California) was used to quantitate serum PD-L1 levels. Stepwise forward Cox multivariable analyses were performed for progression-free survival and overall survival (OS)., Results: In the whole trial population, continuous pretreatment serum PD-L1 levels were not associated with OS. However, within the trastuzumab arm, a higher continuous pretreatment serum PD-L1 level was significant for shorter OS (hazard ratio [HR], 3.85; P = .04), but within the lapatinib arm, pretreatment serum PD-L1 was not associated with OS (P = .37). In the whole trial, in a multivariable analysis for OS, serum PD-L1 (median cut point) remained a significant independent covariate (HR, 2.38; P = .001). There was a significant interaction between treatment arm and continuous serum PD-L1 (bootstrap method; P = .0025): at or above 214.2 pg/mL (the 89th percentile), serum PD-L1 was associated with significantly shorter OS with trastuzumab treatment versus lapatinib treatment., Conclusions: In the CCTG MA.31 trial, serum PD-L1 was a significant predictive factor: a higher pretreatment serum PD-L1 level was associated with shorter OS with trastuzumab treatment but with longer OS with lapatinib treatment. Immune evasion may decrease the effectiveness of trastuzumab therapy. Further evaluation of elevated serum PD-L1 in advanced breast cancer is warranted to identify patients with HER2-positive MBC who may benefit from novel immune-targeted therapies in addition to trastuzumab., (© 2020 American Cancer Society.)

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. We hope that the following analysis may help educate clinicians and ultimately decrease the duration of the mechanical ventilation required by these patients, resulting in improved clinical outcomes and an increase in ventilator availability for other patients in need., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

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. The pathophysiology of acute respiratory distress syndrome (ARDS) in SARS-CoV-2 infection has a component of lung perfusion dysregulation and is described as a "cytokine storm" that causes increased vascular permeability and disease severity. Older adults and those with comorbid conditions, particularly hypertension, diabetes, and history of ischemic heart disease, are especially vulnerable. These high-risk populations are often on angiotensin-modulating therapies, which are theorized to increase ACE2 expressivity, but current evidence for or against discontinuation is equivocal. The standard for SARS-CoV-2 testing is through reverse transcription polymerase chain reaction, which has presented problems due to low sensitivity and possible co-infection with other pathogens. Treatment for ARDS in the setting of SARS-CoV-2 should follow pre-established goals of care and the wishes of the patient and family members or caregivers and consider the high risk for polypharmacy, cognitive decline, malnutrition, and depression, particularly in older adults. Treatment recommendations have outlined ventilation goals to minimize further lung injury. Compassionate use of pharmacologic therapies such as remdesivir has shown promise, and further clinical trials of anticytokine agents are underway., (Copyright© South Dakota State Medical Association.)

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. However, the challenges in classifying and characterizing ESFT complicate effective management and treatment of ES. In this report, we present a rare case of ES metastasis to the pancreas. Upon review of the literature, we found 39 cases of ESFT involving the pancreas, but only 3 were metastatic to the pancreas while the remaining cases of ESFT primarily originated from the pancreas. Given the rarity of such metastasis, the positive outcome in our patient's case may explain the importance of prompt diagnosis in order to initiate appropriate treatment., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Hyma Polimera et al.)
