Primary Diffuse Large B-Cell Lymphoma of the Breast with MYC and BCL2 Rearrangements with Terminal Deoxynucleotidyl Transferase Expression: A Case Report.

Introduction: Primary breast lymphoma represents only 1% of non-Hodgkin lymphomas. The most common histology is diffuse large B-cell lymphoma. When dual translocations of MYC and BCL2 or BCL6 occur, it is referred to as "high-grade B-cell lymphoma with rearrangements of MYC and BCL2 and/or BCL6" according to the 4th edition of the WHO classification of hematolymphoid tumors. The expression of tdt in this type of malignancy is exceptional. Case Report: This is a case of a 54-year-old woman presenting with a rapidly growing painless mass. Ultrasound-guided core biopsy of the breast mass showed infiltrate of medium-sized neoplastic lymphocytes which stained as CD79a-positive B cells co-expressing CD10, BCL2, tdt, and MYC. Ki-67 is positive in 80%. There was rearrangement of MYC and BCL2 at FISH. Positron emission tomography (PET) scan was negative elsewhere. Final diagnosis was a DLBCL of the breast with tdt expression. She was treated with 6 cycles of R-hyperCVAD/MA (R = rituximab, C = cyclophosphamide, V = vincristine, A = cytarabine, D = dexamethasone, M = methotrexate) and intrathecal chemotherapy (IT CT). Restaging PET shows resolution of all avid uptake. We did a review of literature showing the importance of giving an intensive chemotherapy regimen, high-dose methotrexate, cytarabine, and IT CT for central nervous system (CNS) prophylaxis. Conclusion: Primary DLBCL of the breast with rearrangement of MYC and BCL2 and tdt expression is an aggressive disease not very well studied that needs to be treated with an intensive CT and CNS prophylaxis. Stem cell transplant could be given after first remission.

Correlation of Hemoglobin Level With New Inflammatory Markers in the Emergency Department: A Retrospective Study Exploring Neutrophil-to-Lymphocyte, Monocyte-to-Lymphocyte, Platelet-to-Lymphocyte, and Mean Platelet Volume-to-Platelet Count Ratios.

Background Anemia of chronic disease is known to be associated with inflammation. However, the relationship between hemoglobin (Hb) levels and potential inflammatory markers such as neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume-to-platelet count ratio (MPV/PC) has not been extensively studied. The primary objective of this retrospective analytical study conducted at Al Zahraa Hospital University Medical Center (ZHUMC), Beirut, was to investigate the correlation between Hb levels and potential inflammatory markers (NLR, MLR, PLR, MPV/PC) in patients visiting the emergency department (ED), across different genders and age groups. The secondary objectives were to compare Hb levels and inflammatory markers values between the referred medical ward group (the hospitalized patients who were admitted to the medical ward), and the non-referred to medical ward group (the patients who were discharged home from the ED), and to evaluate the predictability of inflammatory markers and Hb levels for referral to the medical ward, including the determination of optimal cutoff values for hospital admission to the medical ward. Methods We analyzed the blood parameters of 379 adult patients who presented to the ED with various medical complaints between September 1, 2022, and November 30, 2022 (three months). These patients were included in the study after we checked their eligibility regarding the verification of all our inclusion and exclusion criteria. Results Our findings revealed a significant negative correlation between Hb levels and PLR (r = -0.24) in both genders and across different age groups. The group referred to the medical ward exhibited lower Hb levels and higher NLR, MLR, and PLR values (P < 0.001). NLR/Hb ratio emerged as a predictive factor for admission in genitourinary (R² = 0.158; OR = 5.62) and respiratory groups (R² = 0.206; OR = 5.89), with specific cutoff values of 0.533 (Sensitivity = 57.1% & Specificity = 84.2%) and 0.276 (Sensitivity = 85% & Specificity = 51.1%), respectively. Conclusions Our study demonstrates that hemoglobin level negatively correlates with PLR. NLR, MLR, and PLR stand as important inflammatory markers. Moreover, we present the first study in the literature to show that NLR/Hb ratio can serve as a predictor for referral to the medical ward, particularly in the genitourinary and respiratory patient groups, underscoring its value in risk assessment as a prognostic marker reflecting the need for admission when the case is more serious.

Cancer research activity in the Arab world: a 15-year bibliometric analysis.

BACKGROUND: The Arab region comprises 22 countries located in the Middle East and North Africa, sharing cultural and linguistic ties. Arab countries have continued to lag in terms of biomedical research compared to other nations for several past decades. Cancer is a major public health concern, being the second leading cause of death globally. Given that high research activity on cancer reflects positively on screening programs, awareness, and clinical practice, this article aimed to examine the activity and trend of cancer research in the Arab world between 2005 and 2019. METHODS: Between 2005 and 2019, the number of cancer-related articles published by each Arab country, and regarding 27 different types, was assessed using the PubMed database. Numbers were normalized with respect to each country's average population and average Gross Domestic Product (GDP). RESULTS: Arab countries contributed to 1.52% of total cancer publications. The number of cancer publications has steadily grown since 2005, with the last 7 years alone witnessing 75.69% of the total Arab cancer-related publications. In terms of publications per million persons, Qatar ranked first (393.74 per million persons), while in terms of publications per national GDP, Egypt ranked first (464.27 per billion US dollars). Breast, liver, and colorectal cancers had the highest numbers of all Arab cancer-related publications, while testicular, vulvar, and gallbladder cancers had the least. CONCLUSIONS: This paper pools information and insight for scientists, clinicians, funders, and decision-makers on the actualities and developments of cancer research in the Arab world. Addressing the barriers facing cancer research remains a cornerstone in the plan to improve the Arab world's output and contribution to the field of oncology.

Utility of hematological and inflammatory biomarkers in predicting recovery in critical Covid-19 patients: Our experience in the largest Covid-19 treating center in Lebanon.

BACKGROUND: COVID-19 pandemic has led to a catastrophic shortage of ICU beds. This has resulted in the need to identify patients that can be discharged early before full clinical recovery. We designed this study to determine if in changes routine tests like CBCD and CRP can be a useful complement to clinical status when deciding to discharge patients from ICU. METHODS: This retrospective study was conducted in Rafic Hariri University Hospital. Levels of biomarkers measured at admission (T1) and within 3 days of outcome (T2) were collected and ratios (T2/T1) were calculated. The Odds Ratios of association between the changes in these biomarkers and outcome were estimated. Multivariate analysis and AUC for the performance of these biomarkers were also conducted. RESULTS: We found on multivariate analysis that reduction in counts of lymphocyte and platelets and elevation in counts of neutrophils and level of CRP (T2/T1 ratio > 1) are strongly associated with mortality with respective ORs estimated at 6.74, 3.26, 5.65 and 4.34 [p-values < 0.001]. AUCs were found to lie in a range of 0.68 to 0.81 indicating fair to good performance. Other factors found to impact survival were AKI, AF and ACS [p-values < 0.01]. In contrast to other studies, risk factors didn't show an association with survival when adjusted for effects of complications and changes in biomarker levels. CONCLUSIONS: Our results confirm that inexpensive tests like lymphocyte count and CRP can be reliably used to follow COVID-19 patients in ICU and to support the decision to discharge patients.

Challenges and perspective of cancer patients during the COVID-19 pandemic and the Lebanese financial crisis: a multicentric cross-sectional study.

Lebanese cancer patients are facing a war on two fronts, between the COVID-19 pandemic and one of the most severe financial crises globally in recent times. This multicentric cross-sectional study was conducted, aiming to analyse challenges and perspective of this particularly vulnerable population. A questionnaire was prepared to assess socio-demographic data, challenges faced during the pandemic, perspectives concerning cancer and COVID-19, a scale was also validated to assess knowledge level regarding COVID-19 in this population. Patients were interviewed in chemotherapy units from four different private and public hospitals in Lebanon during December 2020 and March-June 2021. In total, 272 patients were interviewed (median age, 57 years, range, 22-90 years). Concerning salary during the pandemic, it changed negatively (45.6%), or did not change (7.7%), while 46.7% of participants did not work. Some challenges such as transportation problems (39%), inability to reach their physician by phone (16.9%), deferral of chemotherapy dates (31.6%), difficulty finding chemotherapy medications (49.6%) were more likely to be reported by patients receiving chemotherapy in public compared to private hospitals (p < 0.01 for each). Other challenges include not being able to find non-cancer-related medications (71.3%), this challenge being increased when comparing December 2020 with March-June 2021 (p < 0.02). Using a multivariate analysis, the best predictor for increased knowledge about COVID-19 was higher levels of education (p < 0.001). In conclusion, this study shows that cancer patients in Lebanon are facing many challenges that complicate different aspects of health. Perspective and challenges of these patients must be taken into consideration in order to deliver better care to our patients in these unprecedented times.
