Article Synopsis
  • Tipifarnib is the only effective targeted therapy found for -mutant (mt) head and neck squamous cell carcinoma (HNSCC), which is part of a study analyzing 524 mt solid tumors across various cancer types.
  • The prevalence of mt was highest in urothelial carcinoma (3.0%) and second in HNSCC (2.82%), with notable associations found between mt and immune profile variations in tumor microenvironments, particularly an increase in M1 and CD8+ T-cells in certain cancers.
  • The presence of mt was linked to poorer overall survival in HNSCC compared to other cancer types, highlighting the need for more research to explore the molecular characteristics of mt tumors for potential new

Lung cancer (LC) is the leading cause of cancer death among Hispanic men. We assessed the tendencies for screening eligibility amongst Hispanic prior to LC diagnosis according to the NCCN and The USPSTF guidelines available at the time of diagnosis. We conducted an observational study in patients diagnosed with LC from 2016 to 2019.

Purpose: Hispanic/Latinx communities encounter disparities in access and availability of appropriate timely health care services, negatively affecting cancer outcomes. Limited data exist on the role of these factors in personal experiences of Hispanic/Latinx with health care systems. We aim to better understand Hispanic/Latinx experience with the health care system, focusing on the impact of the Affordable Care Act (ACA) and applications to clinical practice in patients diagnosed with cancer.

Purpose: The HOLA COVID-19 study sought to evaluate the impact of COVID-19 on oncology practices across Latin America (LATAM), challenges faced by physicians, and how practices and physicians adapted while delivering care to patients with cancer.

Methods: This international cross-sectional study of oncology physicians in LATAM included a 43-item anonymous online survey to evaluate changes and adaptations to clinical practice. Multivariable logistic regression analyses were used to evaluate the association of caring for patients with COVID-19 and changes to clinical practice.

Background: Cyclin-dependent kinase 4/6 inhibitors have become part of the standard of care in the treatment of hormone receptor positive, Her2Neu negative metastatic breast cancer. There is concern regarding the efficacy and potential increased cyclin-dependent kinase 4/6 inhibitors toxicity in the geriatric population in the community compared to the clinical trial population.

Methods: We evaluated patients treated with cyclin-dependent kinase 4/6 inhibitors from 2015 to 2019 and stratified according to age ≥70 and <70 years.

Article Synopsis
  • A 26-year-old woman developed a petechial rash and low platelet count (thrombocytopenia) two weeks after receiving the Moderna COVID-19 vaccine, leading to her being admitted to the emergency room.
  • During her hospital stay, her condition was complicated by elevated liver enzymes (transaminitis), which improved after treatment with intravenous steroids and immunoglobulin.
  • Extensive tests ruled out other possible causes for her symptoms, and although there was no definitive proof, the timing of her vaccination suggested that the vaccine might have triggered her health issues.

Purpose: COVID-19 challenged medical practice and graduate medical education. Building on previous initiatives, we describe and reflect on the formative process and goals of the Hematology-Oncology Collaborative Videoconferencing Learning Initiative, a trainee-led multi-institutional virtual COVID-19 learning model.

Methods: Clinical fellows and faculty from 13 US training institutions developed consensus needs, goals, and objectives, recruited presenters, and generated a multidisciplinary COVID-19 curriculum.

Background: Treatment with gemcitabine/nab-paclitaxel confers a survival benefit over gemcitabine monotherapy in patients with advanced pancreatic cancer (APC). However, such treatment can be associated with significant toxicities especially in older patients and carries practical disadvantages related to a weekly schedule along with financial cost. We retrospectively analyzed patients >65 years of age with APC who received a modified biweekly regimen of gemcitabine/nab-paclitaxel to evaluate efficacy and toxicity.

Countries in Latin America and the Caribbean have become hotspots of the novel coronavirus (COVID-19) pandemic, exacerbating socioeconomic inequalities and overwhelming fragmented health systems. Studies from the United States and Europe have highlighted the disproportionate effects of COVID-19 on patients with cancer and the disruption it has caused on cancer care delivery. The HOLA COVID-19 Study aims to understand how cancer care in Latin American countries has been affected by the COVID-19 pandemic.

Severe COVID-19 associated pneumonia and acute respiratory distress syndrome has recently been described with life-threatening features of cytokine storm and loosely referred to as hemophagocytic lymphohistiocytosis (HLH) or macrophage activation syndrome (MAS). Although a recent report indicated favorable responses to the interleukin-1 receptor antagonist, anakinra in eight patients with COVID-19 secondary HLH diagnosed using the HScore calculation, others have suggested that the diagnosis of secondary HLH is uncommon and that the use of the HScore has limited value in guiding immunomodulatory therapy for COVID-19. Here, we provide additional perspective on this important controversy based upon comparisons between 14 COVID-19 cytokine storm patients and 10 secondary HLH patients seen immediately prior to the pandemic.

Background: Histologic subtyping of lung cancer has significant implications for treatment planning. Accurate diagnosis based on cytology/small biopsy specimens is challenging and frequently determined by morphology, as material is often not sufficient for immunohistochemical studies (IHC). We investigated the concordance between the rates of diagnosis from cytology/small biopsies compared with surgical specimens in patients with squamous cell lung cancer (SCC) and the utility of IHC for diagnostic precision in lung cancer subtyping.
