All That Wheezes Is Not Asthma: A Case of Diffuse Large B-Cell Lymphoma of the Larynx

Localized laryngeal lymphoma is a rare entity with an incidence of less than 1% of all laryngeal neoplasms. Diffuse large B-cell lymphoma (DLBCL) is the most common type of laryngeal neoplasms. Here, we describe a case of a young 28-year-old female with large B-cell lymphoma who remained undiagnosed for a long time owing to a myriad of nonspecific presentation including “wheezing.” Although primary laryngeal lymphomas constitute a diagnostic challenge since they are rare, one should have a high index of suspicion for lymphoma of the larynx in patients presenting with unresolved wheezing as it can present catastrophically with acute airway obstruction requiring immediate surgical intervention which was observed in this case. Treatment includes radiotherapy, chemotherapy, immunotherapy, or a combination of these. We hope that the discussions ensuing from case reports regarding uncommon presentations of laryngeal lymphoma may spur the formation of regional/international databases for the description of lymphomas with unusual presentations. This effort can lead to in-depth study of cases and prompt awareness of “rare and subtle presentations” of laryngeal lymphoma

Rivaroxaban: Expanded Role in Cardiovascular Disease Management—A Literature Review

Direct oral anticoagulants (DOACs) are widely used for the prevention of stroke in nonvalvular atrial fibrillation, treatment of deep venous thrombosis and pulmonary embolism, and as prophylaxis after hip and knee surgery after approval by the Food and Drug Administration. In the last decade, DOACs were studied for various indications; this review is focused on rivaroxaban, a factor Xa inhibitor, which is used in an expanded evidence-based fashion for coronary artery disease, peripheral artery disease, heart failure, malignancy, and prophylaxis of deep venous thrombosis in acute medical illnesses

Disease Milestones through Bibliometric Analysis of the Top 100 Cited Articles in Multiple Myeloma

Multiple myeloma (MM) accounts for 1.6% of all cancers and 5%-10% of all hematologic malignancies in the United States (US). Despite marked progress in disease management, it remains incurable with high rates of relapse. We conducted a bibliographic analysis on the Web of Science (WOS) from July 25, 2017 and July 29, 2017. Among the top 100 most-cited articles (1901-2012), the most cited article received 2404 citations and least cited article received 336 citations. Forty-four of 100 articles were published in journals with impact factors greater than 20. We observed that over the years, the focus of research has shifted from diagnosis, staging, and pathogenesis to better treatment outcomes. A subgroup analysis of the top 100 cited articles published in the last five years (2012-2017) demonstrated that several landmark studies, which will likely change the landscape of treating multiple myeloma, were not included in the top 100 list. Interestingly, most of these articles were focused on novel therapeutic agents. This bibliographic analysis provides a list of the 100 top-cited articles in multiple myeloma along with the captivating comprehension of the history and development in various aspects of disease processes. The landscape of this disease is rapidly evolving, and bibliometric studies such as the one presented provide a valuable tool that can highlight the important transitions in the field.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

CDK4/6 inhibitors in advanced hormone receptor-positive/HER2-negative breast cancer: A network meta-analysis (NMA) of randomized controlled trials (RCTs)

e12545 Background: Palbociclib(P), Ribociclib(R) and Abemaciclib(A) in combination with Endocrine therapy (ET) have demonstrated progression free survival (PFS) in patients with metastatic hormone receptor positive, HER2-negative breast cancer as compared to ET alone. In the absence of head to head clinical trials and to provide clinical guidance, we performed an indirect comparison for P, R and A using network Meta-Analysis (NMA). Methods: MEDLINE, EMBASE and the Cochrane Library were searched to identify RCTs comparing P+ET, R+ET, A+ ET vs ET alone. NMA for PFS and toxicity endpoints was conducted using a multivariate random-effects meta-regression, using a consistency model, as described by White and colleagues. We used a frequentist approach and provided a point estimate from the network and a 95% CI from the frequency distribution of the estimate. We also estimated the relative ranking of the different treatments for each outcome using the distribution of the ranking probabilities and the surface under the cumulative ranking curves (SUCRA). Risk of bias was assessed using Cochrane Collaboration tool. Results: 8 RCTs were identified including 4580 patients. Risk of bias was low. 5 RCTs tested CDK 4/6 inhibitors in endocrine naive and 2 in the refractory setting, while MONALESSA-3 included patients both with endocrine naive and endocrine resistant disease. In the endocrine naïve patients, PFS for P was similar when compared indirectly with R (HR, 0.95, 95% CI 0.67-1.35) or A (HR, 1.00, 95% CI 0.62-1.61). Similarly, indirect comparison between R vs A did not show any statistical significant (HR, 0.95, 95% CI 0.62-1.45). In endocrine refractory patients, P showed no difference when compared indirectly to A (HR 1.12, 95% CI 0.67-1.87) or R (HR 0.98, 95% CI 0.52-1.86). R vs A did not show any statistically significant PFS either (HR, 1.14, 95% CI 1.61-4.51). P was ranked first in terms of PFS in frontline setting (SUCRA of 70.5) while R ranked first in the refractory setting (SUCRA of 39.5). QT prolongation was reported for R only. P caused more neutropenia while A caused more fatigue, anemia and diarrhea, although the results were not statistically significant. Conclusions: The efficacy of using either palbociclib, ribociclib or abemaciclib in combination with ET was similar in terms of PFS in either endocrine naïve or resistant disease. Palbociclib causes more neutropenia, abemaciclib causes more fatigue, anemia and diarrhea while ribociclib causes QT prolongation

Role of one, two and three doses of high-dose chemotherapy with autologous transplantation in the treatment of high-risk or relapsed testicular cancer: a systematic review

Approximately 20–30% of patients with metastatic germ cell cancers (GCCs) can develop relapsed or refractory (RR) disease, about 40–50% of patients who relapse after salvage chemotherapy may reach long-term remission. The goal of this review was to identify patients who appear to benefit from high-dose chemotherapy (HDCT) and autologous stem cell transplant (ASCT). To access this, we performed a systematic medical literature review to evaluate the effectiveness of HDCT in the frontline setting, as well as in patients with RR testicular cancer. We searched databases for interventional clinical studies and identified 5883 studies. We selected 49 studies for inclusion, which included a total of 5985 patients. Seventeen studies reported results of newly diagnosed poor-risk GCC patients and 32 studies reported results of RR patients. For newly diagnosed patients with poor prognostic predictors, a risk adjusted strategy using unfavorable tumor marker decline with initial standard chemotherapy regimen and upfront HDCT demonstrated improved outcomes. Our data suggest a minimum of two HDCT cycles with ASCT should be standard of care for patients with RR GCC. Failure of HDCT results in a poor prognosis with only 10% of patients achieving lasting remission with salvage therapy

Gender Differences in Faculty Rank and Leadership Positions Among Hematologists and Oncologists in the United States

PURPOSE: Gender disparity persists in academic medicine. Female faculty are underrepresented in leadership positions and have lower research output. We studied gender differences in faculty rank and departmental leadership and contributing factors among academic hematologists and oncologists in the United States. METHODS: For clinical faculty at 146 hematology or oncology fellowship programs listed in the Fellowship and Residency Electronic Interactive Database, we collected data on demographics, academic rank, and research output using the Doximity and Scopus databases. We compared unadjusted characteristics of men and women by using 2-sided t tests and chi (2) tests where appropriate. To predict probability of full professorship or leadership position among men versus women, we performed multivariable logistic regression analysis adjusted for clinical experience in years, number of publications, h-index, clinical trial investigator status, National Institutes of Health funding, and workplace ranking (top 20 v not). RESULTS: Two thousand one hundred sixty academic hematologists and oncologists were included. Women composed 21.9% (n = 142) of full professors, 35.7% (n = 169) of associate professors, and 45.4% (n = 415) of assistant professors. Thirty percent (n = 70) of departmental leaders were women. Female faculty, compared with male faculty, had a lower mean h-index (12.1 v 20.9, respectively; P < .001) and fewer years of professional experience since fellowship (10 v 16 years, respectively; P < .001). After adjusting for duration of clinical experience, academic productivity, and workplace ranking, the odds of obtaining professorship (odds ratio [OR], 1.05; 95% CI, 0.71 to 1.57; P = .85) or divisional leadership (OR, 0.57; 95% CI, 0.20 to 1.58; P = .28) for female physicians were not different compared with male physicians. CONCLUSION: Gender disparity exists in senior ranks of academic hematology and oncology; however, gender is not a significant predictor in achieving professorship or department leadership position.12 month embargo; published online: 6 February 2020This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
