Favorable outcome of non-myeloablative allogeneic transplantation in adult patients with severe sickle cell disease: A single center experience of 200 patients.

Allogeneic hematopoietic stem cell transplant (HSCT) for adults with severe sickle cell disease (SCD) is potentially curative but not commonly utilized therapy due to complications such as graft failure (GF) and organ toxicity. Herein, we are reporting our long-term outcome data of non-myeloablative (NMA) HSCT in adults with severe SCD with emphasis on factors predicting event free survival (EFS). Adults with severe SCD undergoing NMA match-related donor allogeneic HSCT from 2015 to 2021 with at least 12 months of follow-up were included. A total of 200 patients were included with a median age of 26 years (14-43) and 56% were male. The median infused CD34 dose was 13.7 (5.07-25.8), respectively. Median absolute neutrophil count engraftment was 19 (13-39) days with 51% of patients receiving GCSF to expedite recovery. A total of 17 patients experienced GF; 3 as primary and 14 as secondary within a median time of 204 days (40-905). A 76% successfully discontinued sirolimus at the last follow-up. Median follow-up for the cohort is 29.2 (2.1-71.4) months. Estimated 3-year EFS and OS were 88.2% (81.9-92.5) and 94.6% (89.2-97.3). At multivariable analysis, minor ABC incompatibility hazard ratio (HR) 4 (1.3-12.1; 0.014) and allo-antibody against non-ABO donor antigens HR 4.3 (1.3-14.1; 0.016) were significant for EFS. No clonal evolution or myeloid malignancies were seen. This largest single-center report of NMA HSCT in adults with severe SCD further delineated its feasibility, potential toxicities, and fertility outcomes. GF remains a major impediment and appears dependent on ABO matching and non-ABO antibodies.

Worldwide Network for Blood and Marrow Transplantation Recommendations for Establishing a Hematopoietic Stem Cell Transplantation Program in Countries with Limited Resources, Part II: Clinical, Technical, and Socioeconomic Considerations.

The development of hematopoietic stem cell transplantation (HSCT) programs can face significant challenges in most developing countries because such endeavors must compete with other government health care priorities, including the delivery of basic services. Although this is may be a limiting factor, these countries should prioritize development of the needed expertise to offer state-of-the-art treatments, including transplantation, by providing financial, technological, legal, ethical, and other needed support. This would prove beneficial in providing successful programs customized to the needs of their population and potentially provide long-term cost savings by circumventing the need for their citizens to seek care abroad. The costs of establishing an HSCT program and the costs of the HSCT procedure itself can be substantial barriers in developing countries. In addition, socioeconomic factors intrinsic to specific countries can influence access to HSCT, patient eligibility for HSCT, and timely utilization of HSCT center capabilities. This report describes recommendations from the Worldwide Network for Blood and Marrow Transplantation for establishing HSCT programs, with a specific focus on developing countries, and identifies challenges and opportunities for providing this specialized procedure in resource-constrained settings.

Middle Eastern Expert Opinion: Strategies for Successful Antifungal Stewardship Program Implementation in Invasive Fungal Infections.

In recent years, global public health efforts have increasingly emphasized the critical role of antimicrobial stewardship (AMS) in improving outcomes, reducing costs, and combating the growing threat of antimicrobial resistance. However, antifungal stewardship (AFS) has remained relatively overlooked despite the staggering impact of invasive fungal infections (IFIs). This burden is particularly pronounced in hospitals worldwide, with the Middle East facing significant unmet needs. The rising population of immunocompromised individuals vulnerable to IFI has prompted an increased reliance on antifungal agents for both prevention and treatment. Given the considerable mortality associated with IFIs and the emergence of antifungal resistance, implementing AFS programs in hospital settings is becoming increasingly urgent. In this article, we offer expert insights into the strategies that can be used for successful antifungal stewardship program implementation in IFI. Drawing upon the extensive clinical experience of a multinational and multidisciplinary panel, we present recommendations for optimizing AFS practices. We delve into the challenges and practical considerations of tailoring local AFS initiatives to the evolving landscape of fungal infections. Additionally, we provide actionable recommendations and position statements for the effective implementation of AFS programs, informed by the collective clinical experiences of panel members across their respective countries of practice.

Real-World Registry on the Pharmacotherapy of Multiple Myeloma and Associated Renal and Pulmonary Impairments in the Greater Gulf Region: Protocol for a Retrospective Real-World Data Study.

BACKGROUND: Multiple myeloma (MM) is the second-most common cancer among hematological malignancies. Patients with active disease may experience several comorbidities, including renal insufficiency and asthma, which may lead to treatment failure. The treatment of relapsed or refractory MM (RRMM) has been associated with multiple factors, causing a decline in progression-free survival as well as overall survival with subsequent lines of therapy. Data about the characteristics of this group of patients in the Greater Gulf region are lacking. OBJECTIVE: The primary objective of this study is to describe the disease characteristics and various treatment approaches or regimens used in the management of patients with RRMM in the Greater Gulf region. METHODS: We will conduct a regional, retrospective study collecting real-world and epidemiological data on patients with MM in countries of the Greater Gulf region. Medical records will be used to obtain the required data. Around 150 to 170 patients' records are planned to be retrospectively reviewed over 6 months without any cross-sectional or prospective intervention. Cases will be collected from Saudi Arabia, the United Arab Emirates, Kuwait, Oman, and Qatar. Descriptive as well as analytical statistics will be performed on the extracted data. The calculated sample size will allow us to estimate the percentages of RRMM cases with acceptable precision while complying with the challenges in light of data scarcity. We will obtain a comprehensive description of the demographic profile of patients with MM; treatment outcomes; the proportion of patients with MM with renal impairment and asthma, chronic obstructive pulmonary disease, or both at the time of diagnosis and any subsequent point; and data related to treatment lines, regimens, and MM-associated morbidities. RESULTS: Patient medical records were reviewed between June 2022 and January 2023 for eligibility and data extraction. A total of 148 patients were eligible for study inclusion, of whom 64.2% (n=95) were male and 35.8% (n=53) were female. The study is currently in its final stages of data analysis. The final manuscript is expected to be published in 2024. CONCLUSIONS: Although MM is a predominant hematological disease, data on its prevalence and patients' characteristics in the Greater Gulf region are scarce. Therefore, this study will give us real-world insights into disease characteristics and various management approaches of patients with MM in the Greater Gulf region.

Comparison of a modified pediatric protocol versus a hyper-CVAD protocol in adolescents and young adults with Philadelphia-negative acute lymphoblastic leukemia: A multicenter retrospective analysis.

BACKGROUND: The outcomes of Pediatric acute lymphoblastic leukemia (ALL) have improved dramatically whereas outcomes for ALL amongst adolescents and young adults (AYA) have lagged behind. The introduction of pediatric-like regimens to manage adult ALL has shown promising outcomes across several analyses. MATERIALS AND METHODS: In this analysis, we aimed to retrospectively compare the differences in outcomes among patients aged 14-40 years with Philadelphia-negative ALL treated with a Hyper-CVAD protocol versus a modified pediatric protocol. RESULTS: A total of 103 patients were identified with 58 (56.3%) in the modified ABFM group and 45 (43.7%) in the hyper-CVAD group. The median duration of follow-up for the cohort was 39 months (range 1-93). There were significantly lower rates of MRD persistence after consolidation (10.3% vs. 26.7%, P = 0.031) and transplantation (15.5% vs. 46.6%, P < 0.001) in the modified ABFM group. 5-year OS rates (83.9% vs. 65.3%, P = 0.036) and DFS rates (67.4% vs. 44%, P = 0.014) were higher in the modified ABFM groups. The incidence of grade 3 and 4 hepatotoxicity (24.1% vs. 13.3%, P < 0.001) and osteonecrosis (20.6% vs. 2.2%, P = 0.005) were higher in the modified ABFM group. CONCLUSION: Our analysis demonstrates that the use of a pediatric modified ABFM protocol demonstrated superior outcomes compared to the hyper-CVAD regimen in the treatment of Philadelphia-negative ALL amongst AYA patients. However, the modified ABFM protocol was associated with an increased risk of certain toxicities including high grade liver toxicity and osteonecrosis.

Erdheim-Chester Disease Successfully Treated with Front-Line Single-Agent Dabrafenib.

BACKGROUND Erdheim-Chester disease (ECD) is a clonal disease characterized by histiocytic infiltration of multiple organ systems. As ECD is a rare disorder with variable presentations, its diagnosis and management can present a significant clinical challenge. The diagnosis of ECD requires several clinical, radiological, and histological criteria. Since approximately 75% of ECD patients harbor a mutation in the proto-oncogene BRAF V600E, inhibition of BRAF activation by BRAF inhibitors has significantly improved the management of ECD. Vemurafenib was approved by the U.S. Food and Drug administration for treatment of BRAF-mutated ECD. Another BRAF inhibitor, dabrafenib, has been used in some cases as a single agent and was associated with a lower toxicity profile. CASE REPORT We report the case of a 30-year-old Saudi Arabian woman who initially presented with a history of diffuse abdominal pain and fever. The patient had elevated inflammatory markers, and radiological investigations revealed hypermetabolic regions in the frontoparietal brain lobe, anterior pericardium, kidneys, and the anterior abdominal wall. Histological investigations from the right perinephric soft-tissue mass revealed foamy histiocytes associated with mild chronic inflammation. Furthermore, BRAF V600E was mutated in the biopsy sample, leading to a diagnosis of BRAF-mutated ECD. The patient began single-agent dabrafenib therapy at 75 mg twice daily and experienced an excellent clinical and radiological response with no reported toxicity. CONCLUSIONS Single-agent dabrafenib is effective and well tolerated among ECD patients; therefore, it might be considered as a first-line option for the treatment of BRAF-mutated ECD.

Radiological outcome of bone disease in multiple myeloma patients pre- and post therapy: A single center experience.

OBJECTIVES: To find any correlation between the clinical response as per International Working Myeloma Group (IWMG) response criteria and the radiological response at the end of treatment. METHODS: A retrospective cohort study was conducted, total of 39 patients whom diagnosed with multiple myeloma (MM) between January 2010 and December 2018 and fulfilled the study criteria were included. RESULTS: The high sensitivity and specificity of positron emission tomography/computed tomography (PET/CT) in detecting osteolytic myeloma lesions in the bones was strongly emphasized in our study. Follow up PET/CT, we found that while 17 patients showed complete remission in PET/CT, and 14 of these of patients demonstrated a complete clinical response at end of therapy assessment. CONCLUSION: Although we did not find a statistically significant correlation between the response versus metabolic activity and the number of bone/bone marrow lesions, however, our study was limited by the absence of clear criteria for defining disease response in PET/CT in MM patients. Further prospective analysis would be needed to establish a defined criterion.

Promising remissions in relapsed refractory classical Hodgkin lymphoma patients requiring multiple salvage regimens before transplantation in the brentuximab vedotin era.

Relapsed/refractory classical Hodgkin lymphoma (R/R cHL) patients refractory to first line salvage have poor outcomes. Herein we report the outcome of R/R cHL patients requiring ≥two vs. one line in the era of chemo-immunotherapy. Among 55 R/R cHL patients, 33 (60%) required one, 22 (40%) required ≥two lines. At 2 years, the estimated PFS and OS for patients requiring one vs. ≥two lines was 71.2% (50.1-84.7) vs. 51.9% (27.6-71.6), p= 0.16 and 84.6% (63-94) vs. 84% (58-95), p= 0.88, respectively. Patients requiring ≥two salvage lines prior to HCT can achieve comparable outcomes to those requiring one, possibly due to brentuximab vedotin leading to higher CMR rates.

Management Approach to Acute Myeloid Leukemia Leveraging the Available Resources in View of the Latest Evidence: Consensus of the Saudi Society of Blood and Marrow Transplantation.

PURPOSE: Acute myeloid leukemia (AML) is the most prevalent acute leukemia in adults and is responsible for the majority of cancer-related mortality. In Saudi Arabia, leukemia is ranked the fifth most prevalent type of malignancy in adults. Our aim is to review existing epidemiologic data in Saudi Arabia and develop consensus guidelines for management of AML. METHODS: We review literature related to AML epidemiology, treatment patterns, and outcomes in Saudi Arabia, as well as literature related to the current advances in AML treatment. A panel of 10 experts from eight institutions in Saudi Arabia reviewed the literature and developed a consensus statement. RESULT: We provide an update of the available AML epidemiologic data in Saudi Arabia and describe recent developments in the diagnostic workup, risk stratification, and treatment algorithm. The consensus recommendations for the management of AML in Saudi Arabia were developed. CONCLUSION: The recommendations are in parallel with the recent international guidelines for the diagnosis and management of AML.

Impact of cluster of differentiation 20 expression and rituximab therapy in classical Hodgkin lymphoma: Real world experience.

The prognostic impact of CD20 expression and rituximab therapy in classical Hodgkin lymphoma (cHL) is unclear. Among 310 patients, CD20 was expressed in 66 (22%) cases. The 3-year PFS was 75.1% for CD20+and 70% for CD20- (p = 0.36). The 3-year PFS was 84.7% for the rituximab group and 67.8% for the no rituximab group (p = 0.23). Only constitutional symptoms and positive interim PET/CT were significantly associated with worse outcome, HR 3.2 (1.14-9.01; p = 0.028) and 4.3 (2.27-8.1; p < 0.0001), respectively. Neither CD20 expression nor rituximab use significantly impacted outcome.

Reducing Futile Acute Care Services for Terminally Ill Patients With Cancer: The Dignity Project.

PURPOSE: Patients with terminal diseases frequently undergo interventions that are futile and may be detrimental to their quality of life. We conducted a quality improvement project aimed to reduce the utilization of futile acute care services (ACSs) for patients with cancer treated with a palliative intent. METHODS: A multidisciplinary team reviewed the records of terminally ill patients with cancer who died between November 2017 and May 2018, during their admission at our institution. The review aimed to assess the magnitude of improper utilization of ACSs and admission to the intensive care unit (ICU). Lack of timely documentation of the goals of care (GOCs) was the main reason for this problem. We defined timely documentation as the availability of electronic documentation of patients' GOC before the need for ACSs. Interventions were implemented to improve the process; postintervention data were captured and compared with the baseline data. RESULTS: After the delivery of staff education and the implementation of mandatory documentation of the GOCs in the healthcare electronic record system, the timely documentation of the GOCs for patients with a palliative intent increased significantly from 59% at baseline to 83% in the postintervention phase. The impact of this intervention led to a decrease in admissions to the ICU from 26% to 12% and an estimated annual cost saving of $777,600 in US dollars. CONCLUSION: Our interventions resulted in improved documentation of the GOCs and decrease in the utilization of ACSs including ICU admissions and the associated cost.

Outcome of Middle East Respiratory Syndrome (MERS) in hematology and oncology patients: A case series in Saudi Arabia.

BACKGROUND: Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is associated with a high fatality rate (34%), which is higher in the presence of co-morbidities. The aim of the current study was to assess the clinical course and the outcome in hematological or oncological malignancy cases, diagnosed with MERS-CoV. METHODS: This is a case series of hematological /oncological cases, diagnosed with MERS-CoV, in a tertiary care setting in 2015. The cases were identified based on the World Health Organization (WHO) MERS-CoV case definition. The demographic, clinical, and outcome data were retrieved from the patients' medical charts and electronic health records. RESULTS: In total, nine hematological or oncological cases were identified, diagnosed with MERS-CoV. The baseline malignant condition was hematological malignancy in seven patients, as well as colon cancer and osteosarcoma in one patient each. Six (67%) patients were male. The median age was 65 years (range 16-80 years). Co-morbidities included chronic kidney disease (n = 3.33%), diabetes mellitus (n = 3.33%), and hypertension (n = 2.22%). The presenting symptoms were shortness of breath (n = 6.66%), fever (n = 5.55%), cough (n = 2.22%), and diarrhea (n = 2.22%). Chest x-rays indicated bilateral infiltrates in 6 patients (66%). The PCR (polymerase chain reaction) test was repeated in six patients to confirm the diagnosis. The mortality rate was 100%, and the median time to death was 26 days (range 15-77 days). CONCLUSION: MERS-CoV infection in this small cohort of hematology or oncology patients has a 100% mortality rate, regardless of the status of the underlying disease. The confirmation of the diagnosis may require repeated testing. Additional studies are required to verify the findings and to elucidate the disease pathogenesis in cancer patients.

Highlights of the Management of Adult Histiocytic Disorders: Langerhans Cell Histiocytosis, Erdheim-Chester Disease, Rosai-Dorfman Disease, and Hemophagocytic Lymphohistiocytosis.

Histiocytic disorders are an exceptionally rare group of diseases with diverse manifestations and a paucity of approved treatments, thereby leading to various challenges in their diagnosis and management. With the discovery of novel molecular targets and the incorporation of targeted agents in the management of various adult histiocytic disorders, their management has become increasingly complex. In an attempt to improve the understanding of the clinical features and management of common adult histiocytic disorders (Langerhans cell histiocytosis, Erdheim-Chester disease, Rosai-Dorfman disease, and hemophagocytic lymphohistiocytosis), we created this document based on existing literature and expert opinion.

Venetoclax in combination with carfilzomib and dexamethasone in relapsed/refractory multiple myeloma harboring t(11,14)(q13;q32): two case reports and a review of the literature.

BACKGROUND: Multiple myeloma has witnessed significant advances due to the approval of many novel agents. However, in spite of all these new developments, multiple myeloma remains an incurable disease with inevitable relapse in the majority of patients. Venetoclax is a selective antiapoptotic protein B-cell lymphoma 2 inhibitor that induces cell death in multiple myeloma cells, particularly in those harboring t(11,14)(q13;q32). We report two cases of patients with multiple myeloma with t(11,14)(q13;q32) who were treated with venetoclax/carfilzomib/dexamethasone with rapid initial response; however, the response was short-lived. CASES PRESENTATION: Patient 1 was a 50-year-old Saudi man with International Staging System stage III kappa light chain multiple myeloma with normal karyotype diagnosed in May 2013. He received bortezomib/thalidomide/dexamethasone treatment and underwent autologous hematopoietic stem cell transplant. Three years later, he presented with disease progression and received multiple lines of chemotherapy, including carfilzomib/lenalidomide/dexamethasone. Venetoclax/carfilzomib/dexamethasone was started after acquiring t(11,14)(q13;q32) 5 years into his disease course. He achieved complete remission, with disease progression after cycle 6. Patient 2 was a 48-year-old Saudi man with International Staging System stage III immunoglobulin G kappa multiple myeloma with t(11,14)(q13;q32) diagnosed in May 2017. He received bortezomib/thalidomide/dexamethasone treatment and underwent autologous hematopoietic stem cell transplant. Eighteen months later, he had disease progression, and he received multiple lines of chemotherapy, including carfilzomib/dexamethasone. He was shifted to venetoclax/carfilzomib/dexamethasone in April 2019 and had an initial clinical response; two months later, he progressed to plasma cell leukemia with rapid deterioration to multiorgan failure. CONCLUSIONS: Acquired t(11;14)(q13;q32) is unreported in the multiple myeloma literature. In the era of targeted therapy, it is essential to repeat the cytogenetic and multiple myeloma fluorescence in situ hybridization panel with each disease progression. Multiple myeloma remains a challenging hematological malignancy despite advances in personalized/precision medicine.

Outcome of Oncology Patients Infected With Coronavirus.

PURPOSE: This study investigated the features of oncology patients with confirmed Middle East respiratory syndrome (MERS) at the Ministry of National Guard Health Affairs-Riyadh during the outbreak of June 2015 to determine the clinical course and outcome of affected patients. METHODS: The patients' demographic information, cancer history, treatment pattern, information about MERS-coronavirus (CoV) infection, history of travel, clinical symptoms, test results, and outcome were collected and analyzed as part of a quality improvement project to improve the care and safety of our patients. Only patients with confirmed infection were included. RESULTS: A total of 19 patients were identified, with a median age of 66 years (range, 16-88 years), and 12 patients (63%) were males. The most common underlying disease was hematologic malignancies (47.4%), followed by colorectal cancer (21%) and lung cancer (15.8%). Hypertension and diabetes mellitus were the most common comorbidities (57.9% and 52.6%, respectively). Infection was diagnosed by nasopharyngeal swab in all patients. All patients contracted the infection during their hospitalization for other reasons. Sixteen patients (80%) were admitted to the intensive care unit; 13 patients (81%) had acute respiratory distress syndrome, 11 were intubated (68.75%), 9 had acute renal injury (56.25%), and 3 required dialysis (18.75%). Only 3 patients (15.8%) with early-stage cancers survived. Patients with hematologic malignancies and advanced solid tumors had a 100% case fatality rate. The majority of the causes of death were due to multi-organ failure and septic shock. CONCLUSION: MERS-CoV infection resulted in a high case fatality rate in patients with malignancy. Therefore, it is critical to implement effective primary preventive measures to avoid exposure of patients with cancer to the virus.

Role of Allogeneic HCT as Postremission Therapy for Transplant-Eligible Adult Lymphoblastic Leukemia/Lymphoma After Frontline Hyper-CVAD.

BACKGROUND: Hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone alternating with cytarabine and methotrexate (hyper-CVAD) is a commonly used regimen in adults with acute lymphoblastic leukemia (ALL)/lymphoblastic lymphoma (LBL). Adult patients fit for pediatric-inspired protocols have an excellent outcome with chemotherapy alone. However, it is unclear whether patients receiving hyper-CVAD should undergo allogeneic hematopoietic cell transplantation (HCT) as postremission therapy. Our aim was to examine the role of HCT at first complete remission (CR1) in adult ALL/LBL after hyper-CVAD. PATIENTS AND METHODS: Adult patients with newly diagnosed ALL/LBL receiving frontline hyper-CVAD from 2008 to 2018 were identified and records retrospectively extracted. RESULTS: A total of 85 patients were identified and included for further analysis. The median (range) age was 23 (14-68) years, and 56 (66%) were male. A total of 24 (28%) had adverse cytogenetics, and 48 (56%) had at least one risk factor. All patients received hyper-CVAD as induction; induction failure was seen in 10 (12%). A total of 38 patients continued the hyper-CVAD course, while the remaining 47 received HCT in CR1. Three-year event-free survival (EFS) and overall survival for the entire cohort were 51.4% and 61.6%, respectively. Median follow-up of alive patients was 39.9 (3.8-123.8) months. At multivariable analysis for EFS, induction failure was associated with worse outcome (hazard ratio [HR], 4.8; 95% confidence interval [CI] 1.7-13.7; P = .003), whereas HCT in CR1 improved outcome (HR, 0.42; 95% CI 0.18-0.97; P = .044). Furthermore, HCT in CR1 was the only prognostic factor for overall survival (HR, 0.3; 95% CI 0.11-0.85; P = .023). CONCLUSION: HCT at CR1 resulted in a favorable EFS and overall survival in ALL/LBL patients after hyper-CVAD frontline therapy. Given that hyper-CVAD is a widely used protocol for adult patients, further examination of this observation is warranted.

Optimal pre-emptive cytomegalovirus therapy threshold in a patient population with high prevalence of seropositive status.

INTRODUCTION: Preemptive therapy (PET) for cytomegalovirus (CMV) reactivation post allogeneic hematopoietic stem cell transplantation (SCT) was shown to decrease the incidence of CMV disease. However, the optimal PET threshold is elusive. PURPOSE OF THE STUDY: To examine the efficacy of PET initiation at a viral threshold of 1000 copies/mL (1560 IU/mL) in a patient population with high prevalence of CMV seropositive status. PATIENTS AND METHODS: A single center retrospective review of patients that underwent allogeneic SCT was done. RESULTS: A total of 195 allogeneic SCT recipients were included with median follow up of 18.1 (0.7-95.6) months. A total of 178 (91 %) of patients had a positive CMV PCR with median days to initial reactivation post SCT of 17 (1-1187); 129 patients had peak CMV titer < 1000 copies/mL (low titer) whereas the remaining 49 patients had a peak titer ≥ 1000 copies/mL (high titer). 120 (93 %) of patients with low titers cleared spontaneously with median time to clearance of 40 days (4-188). One patient in the high titer group developed CMV disease. At multivariable analysis; age at SCT HR 1.02 (1.004-1.04; 0.017), malignant vs. benign condition HR 9.4 (2.47-61; 0.0005) and cGVHD HR 0.37 (0.2-0.65; 0.0005) were significant for OS. CONCLUSIONS: CMV reactivation post SCT was very common in patients with high prevalence of seropositive status. A PET threshold of 1000 copies/mL (1560 IU/mL) appears desirable as it was associated with spontaneous clearance in over 90 % of patients while minimizing treatment related toxicity. Validation of these observations is warranted.

Saudi Lymphoma Group's Clinical Practice Guidelines for Diagnosis, Management and Follow-up of Patients with Various Types of Lymphoma during the Coronavirus Disease 2019 Pandemic.

The Saudi Lymphoma Group had previously published recommendations on the management of the major subtypes of lymphoma. However, the effect the currently ongoing coronavirus disease 2019 (COVID-19) pandemic has on the management of patients with lymphoma has been paramount. Therefore, the Saudi Lymphoma Group has decided to provide clinical practice guidelines for the diagnosis, management and follow-up of patients with various types of lymphoma during the COVID-19 pandemic.

Managing Oncology Services During a Major Coronavirus Outbreak: Lessons From the Saudi Arabia Experience.

Outbreaks of infectious etiology, particularly those caused by a novel virus that has no known treatment or vaccine, may result in the interruption of medical care provided to patients with cancer and put them at risk for undertreatment in addition to the risk of being exposed to infection, a life-threatening event among patients with cancer. This article describes the approach used to manage patients with cancer during a large-scale Middle East respiratory syndrome-coronavirus hospital outbreak in Saudi Arabia to ensure continuity of care and minimize harm from treatment interruption or acquiring infection. The approach taken toward managing this high-risk situation (COVID-19) could be easily adopted by health care organizations and would be helpful to ensure readiness for the occurrence of future outbreaks of different infectious etiologies like those recent episodes of new coronavirus.

Impact of age and induction therapy on outcome of 180 adult patients with acute myeloid leukemia; retrospective analysis and literature review.

The prognosis of acute myeloid leukemia (AML) remains poor. Among 180 patients, the median age was 53 (14-88) years. The overall 2-year disease free survival (DFS) was 28.6% (+/- 3.4), 47.7% (+/- 6.6%) for ≤ 40, 23.6% (+/- 5.8%) for 41-60 and 11.7% (+/- 4.2%) for ≥61 (p< 0.0001). The overall 2-year survival (OS) was 45.3% (+/- 3.8%), 78.6% (+/- 5.5%) for ≤40, 43.5% (+/- 6.9%) for 41-60 and 15.8% (+/- 4.8%) for ≥61 (p< 0.0001). Induction outcome of ≥61 was best in high dose chemotherapy (HDC) group (p < 0.0001). Only those ≤40 had durable DFS and OS. HDC appears to improve the outcome of older AML patients.
