Disparities in Electronic Cigarette Use: A Narrative Review.

The prevalence of electronic cigarette use has been declared an epidemic by the U.S. Surgeon General in 2018, particularly among youth aged 18-24 years old. Little is known about the differential use of e-cigarettes by different groups. PubMed, Cochrane, and Google Scholar were used to find relevant articles. A total of 77 articles were included. The extant literature reveals disparities in e-cigarette use by race/ethnicity and sexuality/gender. There are conflicting conclusions regarding disparities by socioeconomic status.

The Genomic, Transcriptomic, and Immunologic Landscape of HRAS Mutations in Solid Tumors.

Tipifarnib is the only targeted therapy breakthrough for HRAS-mutant (HRASmt) recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). The molecular profiles of HRASmt cancers are difficult to explore given the low frequency of HRASmt. This study aims to understand the molecular co-alterations, immune profiles, and clinical outcomes of 524 HRASmt solid tumors including urothelial carcinoma (UC), breast cancer (BC), non-small-cell lung cancer (NSCLC), melanoma, and HNSCC. HRASmt was most common in UC (3.0%), followed by HNSCC (2.82%), melanoma (1.05%), BC (0.45%), and NSCLC (0.44%). HRASmt was absent in Her2+ BC regardless of hormone receptor status. HRASmt was more frequently associated with squamous compared to non-squamous NSCLC (60% vs. 40% in HRASwt, p = 0.002). The tumor microenvironment (TME) of HRASmt demonstrated increased M1 macrophages in triple-negative BC (TNBC), HNSCC, squamous NSCLC, and UC; increased M2 macrophages in TNBC; and increased CD8+ T-cells in HNSCC (all p < 0.05). Finally, HRASmt was associated with shorter overall survival in HNSCC (HR: 1.564, CI: 1.16-2.11, p = 0.003) but not in the other cancer types examined. In conclusion, this study provides new insights into the unique molecular profiles of HRASmt tumors that may help to identify new targets and guide future clinical trial design.

Implementing physician education to increase lung cancer screening uptake.

Aim: Lung cancer (LC) is the leading cause of cancer-related deaths worldwide. The US Preventive Services Task Force and National Comprehensive Cancer Network recommend annual low-dose computed tomography (LDCT) for eligible adults. We conducted a study to assess physician LDCT referral patterns. Methods: The study was divided into a pre-, intervention, and post-intervention periods. The intervention was a LC screening educational series. We evaluated rates of LDCT screening referrals during pre- and post-intervention periods. Results: In the pre-intervention period, 75 patients fulfilled US Preventive Services Task Force and/or National Comprehensive Cancer Network criteria and 27% underwent LDCT. In the post-intervention period, 135 patients fulfilled either screening criteria of whom 61.5% underwent LDCT. Conclusion: In our study, educational lectures improved compliance significantly and should be used as tool for primary care providers to effectively increase LDCT screening referrals.

A deep dive into CDK4/6 inhibitors: Evaluating real world toxicities and treatment paradigms in the elderly population.

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. Complete blood count from the first two cycles was recorded. Rates of hematologic toxicities, dose interruptions and reductions, progression-free survival, and overall survival were compared between both groups. We sought to assess the hematologic toxicities between the age groups and the relationship between previous chemotherapy exposure, bone metastasis and starting cyclin-dependent kinase 4/6 inhibitors dose with progression-free survival and overall survival. RESULTS: A total of 202 patients were included, 73 were ≥70 years and 129 were <70 years of age. There was no association between age group and grade of neutropenia or thrombocytopenia. There was a profound association between progression-free survival and overall survival and starting dose, where patients with recommended starting dose had higher progression-free survival and overall survival than those with a reduced dose (p = 0.0003 and p = 0.04). CONCLUSIONS: Our study showed similar progression-free survival and overall survival between age groups without significant differences in neutropenia or thrombocytopenia toxicity. Nevertheless, we found an association between starting dose and progression-free survival and overall survival that has not been previously reported. Given the good tolerability across age groups and the improvement in progression-free survival and overall survival, patients should be treated at the cyclin-dependent kinase 4/6 inhibitors recommended dose and monitored appropriately.

One size does not fit all: Evaluating disparities in lung cancer screening eligibility amongst the Hispanic population.

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. Charts were reviewed to assess their screening eligibility prior to LC. The chi-square test was used to examine the association between race and ethnicity with each screening criteria. A total of 530 subjects were reviewed, of which 432 were included in the analysis. One hundred fifty-three and 245 subjects were ineligible for screening under NCCN and USPSTF criteria prior to their LC diagnosis. Twenty-eight of the subjects who did not fulfill NCCN criteria identified as AA and 12 as Hispanics. Forty and 20 of the USPSTF screening ineligible subjects identified as AA and Hispanics. There was a significant association between screening eligibility criteria in Hispanics, with 52% Hispanic subjects meeting NCCN criteria compared to only 20% who met USPSTF (p=0.0184). There was also a significant association between ethnicity and USPSTF eligibility criteria (p=0.0166), as 80% of Hispanic subjects were screening ineligible under USPSTF criteria compared to 56% of non-Hispanic or other. In our study, Hispanics had significantly lower tendencies of meeting the USPSTF LC screening eligibility criteria than non-Hispanics or other. Interestingly, a proportionally higher number of Hispanics who were ineligible under USPSTF criteria met NCCN criteria. These findings suggest that leniency in the screening criteria can possibly lead to earlier detection of LC in high-risk individuals. Recently, USPSTF has modified their criteria which may benefit more of these individuals. To improve rates of screening and overall mortality of minorities, organizations should continue to re-evaluate and liberalize their screening guidelines.

Proyecto ELEVAR: Evaluating the Latinx Experience With the Health Care System Through Variables on Access and Resources.

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. METHODS: Competitively obtained data from 2010 to 2019 Association of American Medical Colleges Consumer Survey of Health Care Access (a US population-based sample of potential health care consumers needing health care at least once in the past year) were retrospectively reviewed. Descriptive statistics and univariate and multivariate comparisons of patterns pre- versus post-ACA were performed for respondents self-identifying as Hispanic/Latinx. RESULTS: In a total cohort of 53,523 respondents, Hispanic/Latinx comprised 7.5% (n = 4,094). Post-ACA demographics showed a higher proportion of female and an increase in employment, educational attainment, income, and private insurance coverage, with a decrease in uninsured. Adjusted models showed that post-ACA Hispanic/Latinx patients are less likely to use emergency room if sick or needing medical advice (odds ratio [OR] 0.33; P < .001) and more likely to report chronic conditions involving cancer (OR 2.43; P < .001) or being limited in activities because of mental or emotional problems (OR 1.36; P = .005). CONCLUSION: Although ACA implementation was associated with decreased health care access barriers in Hispanic/Latinx, they continue to experience disparities in chronic health conditions, including cancer, with higher limitations because of emotional or mental health. Ongoing efforts that build upon current strides, toward improved patient satisfaction and overall outcomes, are of paramount importance.

HOLA COVID-19 Study: Evaluating the Impact of Caring for Patients With COVID-19 on Cancer Care Delivery in Latin America.

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. RESULTS: A total of 704 oncology physicians from 19 countries completed the survey. Among respondents, the most common specialty was general oncology (34%) and 56% of physicians had cared for patients with COVID-19. The majority of physicians (70%) noted a decrease in the number of new patients evaluated during the COVID-19 pandemic when compared with prepandemic, and 73% reported adopting the use of telemedicine in their practice. More than half (58%) of physicians reported making changes to the treatments that they offered to patients with cancer. In adjusted models, physicians who had cared for patients with COVID-19 had higher odds of changing the type of chemotherapy or treatments that they offered (adjusted odds ratio 1.81; 95% CI, 1.30 to 2.53) and of delaying chemotherapy start (adjusted odds ratio 2.05; 95% CI, 1.49 to 2.81). Physicians identified significant delays in access to radiation and surgical services, diagnostic tests, and supportive care. CONCLUSION: The COVID-19 pandemic has significantly disrupted global cancer care. Although changes to health care delivery are a necessary response to this global crisis, our study highlights the significant disruption and changes to the treatment plans of patients with cancer in LATAM resulting from the COVID-19 health care crisis.

Missed Opportunities? An Observational Analysis of Lung Cancer Screening Utilization Amongst Patients With Lung Cancer.

Lung cancer (LC) is the leading cause of cancer-related deaths worldwide. The U.S. Preventive Services Task Force (USPSTF) and National Comprehensive Cancer Network (NCCN) recommend annual low-dose CT chest (LDCT) for LC screening in high-risk adults who meet appropriate criteria, which primarily focus on age and smoking history. Despite this, screening rates remain low and patients with LC are typically diagnosed at a later stage.We conducted a single-center retrospective analysis of patients with an established diagnosis of lung cancer to evaluate if screening guidelines were appropriately followed before the cancer diagnosis.Patients diagnosed with LC between 2016 and 2019 were included in the analysis. Charts were reviewed for demographics, detailed smoking history, as well as histology and stage of LC. Associations between categorical factors and screening were examined using the chi-square test. Associations between continuous and ordinal factors and screening were examined using the Mann-Whitney test.A total of 530 charts were reviewed, of which 52% met NCCN criteria and 35% met USPSTF criteria. Only 4.0% and 4.8% of patients who met NCCN and USPSTF criteria, respectively, underwent screening. There was a significant association between staging at diagnosis and screening with LDCT. All the patients who had screening CT scans were diagnosed at localized stages of lung cancer in both NCCN and USPSTF groups compared to 49.1% and 48% in eligible subjects that did not undergo screening, respectively.Our study showed that despite established guidelines for LC screening and insurance coverage, a vast majority of screening-eligible LC patients have never had LDCT. We found that patients who underwent screening as per guidelines were diagnosed at earlier stages of the disease. Ongoing efforts to increase awareness and adherence to LC screening guidelines are needed to improve early detection and reduce LC mortality.

Forming the Hematology-Oncology Collaborative Videoconferencing (CO-VID) Learning Initiative: Experiential Lessons Learned From a Novel Trainee-Led Multidisciplinary Virtual Learning Platform.

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. Weekly Zoom conferences consisted of two trainee-led instructional segments and a trainee-moderated faculty Q&A panel. Hematology-oncology training program faculty and trainees were the targeted audience. Leadership evaluations consisted of anonymized baseline and concluding mixed methods surveys. Presenter evaluations consisted of session debriefs and two structured focus groups. Conference evaluations consisted of attendance, demographics, and pre- or postmultiple-choice questions on topic learning objectives. RESULTS: In 6 weeks, the initiative produced five conferences: antivirals, anticoagulation, pulmonology, provider resilience, and resource scarcity ethics. The average attendance was 100 (range 57-185). Among attendees providing both pre- and postconference data, group-level knowledge appeared to increase: antiviral (n = 46) pre-/postcorrect 82.6%/97.8% and incorrect 10.9%/2.2%, anticoagulation (n = 60) pre-/postcorrect 75%/93.3% and incorrect 15%/6.7%, and pulmonary (n = 21) pre-/postcorrect 66.7%/95.2% and incorrect 33.3%/4.8%. Although pulmonary management comfort appeared to increase, comfort managing of antivirals and anticoagulation was unchanged. At the conclusion of the pilot, leadership trainees reported improved self-confidence organizing multi-institutional collaborations, median (interquartile range) 58.5 (50-64) compared with baseline 34 (26-39), but did not report improved confidence in other educational or leadership skills. CONCLUSION: During crisis, trainees built a multi-institutional virtual education platform for the purposes of sharing pandemic experiences and knowledge. Accomplishment of initiative goals was mixed. Lessons learned from the process and goals may improve future disaster educational initiatives.

Immune thrombocytopenic purpura and acute liver injury after COVID-19 vaccine.

A 26-year-old woman was sent to the emergency room by her primary care physician for a new petechial rash and thrombocytopenia 2 weeks after receiving the Moderna mRNA-1273 SARS-CoV-2 vaccine. Her hospital course was complicated by transaminitis. Her platelet count improved to normal on hospital day 5 after receiving intravenous steroids and intravenous immunoglobulin to treat her suspected diagnosis of immune thrombocytopenic purpura. Extensive workup for her thrombocytopenia and transaminitis was unremarkable including ruling out infectious, autoimmune and toxic causes. A liver biopsy was unrevealing and her transaminitis was improved on discharge. Although not proven, the temporal relationship of her vaccination with thrombocytopenia and abnormal liver enzymes points towards the Moderna mRNA-1273 SARS-CoV-2 vaccine as the most likely inciting factor.

First Analysis of Same-day Pegfilgrastim Use with Concurrent Capecitabine-based Regimens in Patients with Gastrointestinal Malignancies.

BACKGROUND: Pegfilgrastim is administered 24 hours. after chemotherapy to reduce risks of myelosuppression. This requires an additional clinic visit, which can be difficult for some patients (pts) due to work and transportation issues. In GI malignancies, patients receiving capecitabine-based regimens also require pegfilgrastim to reduce myelotoxicity. We present here the first study to analyze safety and efficacy of administering pegfilgrastim on the same day as capecitabine-based regimens in patients with GI malignancies. METHODS: We evaluated 157 patients with GI malignancies who received a capecitabine-based chemotherapy regimen, including XELOX, EOX, ECX, XELIRI, MIXE, gemcitabine-capecitabine and same-day pegfilgrastim (6 mg) within 1 hr of completion of systemic agents. As per institutional guidelines, patients were counseled on risks of same-day pegfilgrastim prior to its administration. Patients were followed to determine the degree of neutropenia and toxicity. RESULTS: A total of 914 chemotherapy cycles in 157 patients were analyzed. Median ANC nadir for all cycles was 5634/uL (range: 450 - 23800). Grade 1 and 2 neutropenia developed in 11 of 914 cycles. Bone pain reported in 9 pts. There was 1 episode of grade >3 neutropenia resulting in infection and antibiotic use. No other patient required dose reductions, chemotherapy delays, or hospitalizations. No increased toxicity of capecitabine was noticed. CONCLUSIONS: We believe our study is the first in GI malignancies to report that same-day pegfilgrastim administration with capecitabine-based regimens may be as effective and safe as next-day administration. Additionally, given the absence of CD in human bone marrow, it appears capecitabine can be used concurrently with pegfilgrastim. Prospective studies should be done to further investigate, as this practice can benefit patients clinically, decrease office visits, increase patient's satisfaction and reduce healthcare costs.

Secondary hemophagocytic lymphohistiocytosis versus cytokine release syndrome in severe COVID-19 patients.

IMPACT STATEMENT: 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. We hypothesize that identification of HLH may relate to the severity or timing of cytokine release and suggest distinguishing between cytokine release syndrome and secondary HLH, reserving the latter term for cases fulfilling diagnostic criteria.

Attenuated regimen of biweekly gemcitabine/nab-paclitaxel in patients aged 65 years or older with advanced pancreatic cancer.

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. METHODS: Patients aged >65 years with chemo-naïve APC with Eastern Cooperative Oncology Group performance status ⩽2 were studied. Patients were treated with a modified regimen of gemcitabine 1000 mg/m2 and nab-paclitaxel 125 mg/m2 every 2 weeks on days 1 and 15 of a 28-day cycle. Patients were evaluated for progression-free survival (PFS) and overall survival (OS) with analyses performed using the Kaplan-Meier method. Adverse events were recorded on the day of chemotherapy. Cancer antigen 19.9 was measured in every cycle and restaging scans were performed every two cycles. RESULTS: A total of 73 patients (median age: 73 years; range: 66-93) were treated with biweekly gemcitabine/nab-paclitaxel as first-line treatment. The median OS and PFS were 9.1 months and 4.8 months, respectively. Around 66% of patients received growth-factor support based on American Society of Clinical Oncology guidelines and no patient developed neutropenic fever. The incidences of grade ⩾3 toxicity for neutropenia, anemia, thrombocytopenia, and neurotoxicity were 2%, 7%, 3%, and 5%, respectively. Dose reductions of gemcitabine/nab-paclitaxel were required in 10% and 4% patients, respectively. CONCLUSION: In patients older than >65 years of age with APC, a modified regimen of biweekly gemcitabine/nab-paclitaxel was found to be effective when compared with the historical control from the MPACT study. This regimen allowed for fewer dose reductions, reduced healthcare costs from additional appointments, travel-related cost, as well as a favorable side-effect profile while maintaining efficacy. Though retrospective in nature, this study underlines the need for further investigation, particularly in elderly patients with poor performance status, such as those with pancreatic cancer, and in order to combine with a third agent, such as a targeted treatment or immunotherapy.

The HOLA COVID-19 Study: An International Effort to Determine How COVID-19 Has Impacted Oncology Practices in Latin America.

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.
