ABSTRACT
Background: The current trends in lymphoma cases from Saudi Arabia and their long-term survival are unknown. This study was conducted to evaluate the trends of lymphoma diagnoses and survival from a major tertiary care hospital in Saudi Arabia. Methods: This retrospective study included all new cases of lymphoma diagnosed in adults (age ≥18 years) at King Saud University Medical City, Riyadh, Saudi Arabia, from 2008 to 2018, as identified from the Saudi Cancer Registry. Data on the demographics and clinical characteristics were collected, the survival outcomes were estimated, and multivariate analysis of the overall survival was calculated. Results: A total of 422 patients were included (median age: 46 years). The number new cases of lymphoma diagnosed variably increased over the study period: From 28 (7%) cases in 2009 to 48 (11%) in 2018. The most common lymphoma was diffuse large B-cell lymphoma (175; 41%): and extranodal site was GI involvement (33.5%). In terms of survival, 79% were alive at the last follow-up. On multivariable analysis, the hazard ratio (HR) for patients aged ≥60 years was 3.44 (95% CI: 2-5.9; P = 0.0000069), adjusted for lactate dehydrogenase level (LDH) and disease stage. For advanced-stage disease and high LDH, the HR was 4.2 (95% CI: 1.5-11.8, P = 0.00637) and 0.5 (95% CI: 0.28-0.97; P = 0.04106), respectively. Conclusions: The lymphoma trend in the Saudi Arabian population showed variable increase in cases over the study period, with most patients presenting with advanced-stage disease and at a younger age. The overall survival was comparable with studies from Western countries.
ABSTRACT
Objectives To estimate the current prevalence of bone marrow involvement in classical Hodgkin lymphoma (HL) patients diagnosed at King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia. Methods A cross-sectional study was conducted among classical Hodgkin's lymphoma patients, diagnosed between 2015 and 2021 at KKUH. We retrospectively collected clinical and pathological information from all adult patients aged 18 years or older with a diagnosis of HL. Survival analyses were performed using the log-rank test and Kaplan-Meier curves. Results The study included 140 patients, 60 (42.86%) of whom were female. Bone marrow involvement was seen in 15 (10.71%) patients, 58 (41.43%) patients had an advanced-stage disease, and 20 (14.29%) patients had gastrointestinal involvement. Patients with bone marrow involvement had a median survival of 71 months (95% confidence interval (CI): 16.7-125.3) compared to patients without bone marrow involvement who had a median survival of 68 months (95% CI: 50.7-85.3). Conclusion The prevalence of bone marrow involvement in HL patients, as well as the proportion of patients presenting with advanced disease at the time of diagnosis, was higher compared to Western data. This could be attributed to a delay in diagnosis or more aggressive disease biology.
ABSTRACT
BACKGROUND: The management of pregnant women with sickle cell disease (SCD) poses a major challenge for maternal healthcare services owing to the potential for complications associated with morbidity and mortality. Trustworthy evidence-based clinical practice guidelines (CPGs) have a major impact on the positive outcomes of appropriate healthcare. The objective of this study was to critically appraise the quality of recent CPGs for SCD in pregnant women. METHODS: Clinical questions were identified and the relevant CPG and bibliographic databases were searched and screened for eligible CPGs. Each CPG was appraised by four independent appraisers using the AGREE II Instrument. Inter-rater analysis was conducted. RESULTS: Four eligible CPGs were appraised: American College of Obstetricians and Gynecologists (ACOG), National Heart, Lung, and Blood Institute (NHLBI), National Institute of Health and Care Excellence (NICE), and Royal College of Obstetricians and Gynaecologists (RCOG). Among them, the overall assessments of three CPGs (NICE, RCOG, NHLBI) scored greater than 70%; these findings were consistent with the high scores in the six domains of AGREE II, including:[1] scope and purpose,[2] stakeholder involvement,[3] rigor of development,[4] clarity of presentation,[5] applicability, and [6] editorial independence domains. Domain [3] scored (90%, 73%, 71%), domain [5] (90%, 46%, 47%), and domain [6] (71%, 77%, 52%) for NICE, RCOG, and NHLBI, respectively. Overall, the clinical recommendations were not significantly different between the included CPGs. CONCLUSIONS: Three evidence-based CPGs presented superior methodological quality. NICE demonstrated the highest quality followed by RCOG and NHLBI and all three CPGs were recommended for use in practice.
