Several new agents have been introduced in the palliative treatment of advanced and metastatic NSCLC in the recent years. In randomized trials, the new third-generation regimens showed comparable efficacy to each other, but a better response rate and time to progression combined with a remarkably improved tolerability compared to "classic schedules". In patients who are not suitable for platinum-based therapy, monotherapy could be an attractive opportunity, as shown in randomized trials. In second-line therapy, the novel antifolate Pemetrexed showed comparable activity to Docetaxel with significantly reduced toxicity. Among the new oral tyrosine kinase inhibitors, Erlotinib proved to be active in second- and third-line treatments, whereas in first-line treatment, no survival benefit has been observed to date.

Real-world clinical outcome of unresectable locally advanced & de-novo metastatic pancreatic ductal adenocarcinoma: a multicentre retrospective study.
BMC Cancer

Department of Medical Oncology, Cancer Centre of Excellence, King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia.
Background: Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal malignancies, with limited treatment options yielding poor outcomes. This study aimed to evaluate the real-world clinical characteristics, treatment patterns, and outcomes of patients with locally advanced unresectable and de-novo metastatic PDAC in Saudi Arabia, providing regional data to compare with international benchmarks.
Methods: This is a retrospective, multicentre study involving 350 patients diagnosed with unresectable locally advanced or de-novo metastatic PDAC between January 2015 and November 2023.

Hematopoietic stem cell transplantation (HSCT) is a highly effective therapy for malignant blood illnesses that pose a high risk, as well as diseases that are at risk due to other variables, such as genetics. However, the prevalence of graft-versus-host disease (GVHD) has impeded its widespread use. Ensuring the stability of microbial varieties and associated metabolites is crucial for supporting metabolic processes, preventing pathogen intrusion, and modulating the immune system.

Purpose: This study seeks to resolve a fundamental question in oncology: Why do appendiceal and colorectal adenocarcinomas exhibit distinct liver metastasis rates? Building on our prior hypothesis published in the British Journal of Surgery, our institution has investigated potential DNA mutations within the carcinoembryonic antigen-related cell adhesion molecule (CEACAM5) gene's Pro-Glu-Leu-Pro-Lys (PELPK) motif to evaluate its role as a biomarker for liver metastasis risk.
Methods: Partnering with the Australian Genome Research Facility, the PELPK motif of CEACAM5 was analysed in colorectal and appendiceal adenocarcinomas to detect DNA mutations associated with liver metastasis. Additionally, our institution performed the COPPER trial to assess carcinoembryonic antigen (CEA) levels in portal versus peripheral blood in patients with appendiceal adenocarcinoma and a systematic review and meta-analysis of 136 studies on CEA's prognostic significance among patients with colorectal and appendiceal adenocarcinoma.
Personalized, autologous neoantigen-specific T cell therapy in metastatic melanoma: a phase 1 trial.

New treatment approaches are warranted for patients with advanced melanoma refractory to immune checkpoint blockade (ICB) or BRAF-targeted therapy. We designed BNT221, a personalized, neoantigen-specific autologous T cell product derived from peripheral blood, and tested this in a 3 + 3 dose-finding study with two dose levels (DLs) in patients with locally advanced or metastatic melanoma, disease progression after ICB, measurable disease (Response Evaluation Criteria in Solid Tumors version 1.1) and, where appropriate, BRAF-targeted therapy.

Aneurysmal Subarachnoid Hemorrhage (aSAH), resulting from ruptured aneurysms, is a major contributor to stroke-related mortality and morbidity. Despite advances in healthcare, aSAH remains severe and often leads to complications such as cerebral vasospasm (CV), cerebral infarction, and delayed ischemic neurological deficits (DIND). Clazosentan, an endothelin receptor antagonist, has demonstrated potential in alleviating vasospasm and its associated outcomes, although evidence of its efficacy remains unclear.
