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; = 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, = 0.00637) and 0.5 (95% CI: 0.28-0.97; = 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.

Antibody-drug conjugates (ADCs) have emerged as a promising strategy in targeted cancer therapy, enabling the precise delivery of cytotoxic agents to tumor sites while minimizing systemic toxicity. However, traditional ADCs face significant limitations, including restricted drug loading capacity, where an optimal drug-to-antibody ratio (DAR) is crucial; low DARs may lead to insufficient potency, while high DARs can cause rapid clearance and increased toxicity. Additionally, ADCs often suffer from instability in circulation due to the potential for premature release of cytotoxic agents, resulting in off-target effects and reduced therapeutic efficacy.

Globally, the incidence and death rates associated with cancer persist in rising, despite considerable advancements in cancer therapy. Although some malignancies are manageable by a mix of chemotherapy, surgery, radiation, and targeted therapy, most malignant tumors either exhibit poor responsiveness to early identification or endure post-treatment survival. The prognosis for prostate cancer (PCa) is unfavorable since it is a perilous and lethal malignancy.

Alopecia areata (AA) is an autoimmune condition marked by hair loss, linked to inflammatory processes involving the interleukin-1 receptor type 1 (IL-1R1) pathway. This study aims to explore the relationship between IL-1R1 gene expression, serum IL-1R1 levels, and hsa-miR-19b-3p in relation to AA severity. Using a case-control design, we assessed 100 AA patients and 100 healthy controls, measuring serum IL-1R1 through enzyme-linked immunosorbent assay (ELISA) and analyzing IL-1R1 gene and hsa-miR-19b-3p expression levels via quantitative real-time PCR (qRT-PCR).
