Phase II randomized study of dostarlimab alone or with bevacizumab versus non-platinum chemotherapy in recurrent gynecological clear cell carcinoma (DOVE/APGOT-OV7/ENGOT-ov80).

Background: Recurrent gynecological clear cell carcinoma (rGCCC) has a low objective response rate (ORR) to chemotherapy. Previous preclinical and clinical data suggest a potential synergy between immune checkpoint inhibitors and bevacizumab in rGCCC. Dostarlimab, a humanized monoclonal antibody targeting programmed cell death protein 1 (PD-1), combined with the anti-angiogenic bevacizumab, presents a novel therapeutic approach.

Decision-making about palliative sedation for patients with cancer: a qualitative study in five European countries linked to the Palliative sedation project.

Background: Palliative sedation refers to the proportional use of titrated medication which reduces consciousness with the aim of relieving refractory suffering related to physical and psychological symptoms and/or existential distress near the end of life. Palliative sedation is intended to be an end of life option that enables healthcare professionals to provide good patient care but there remains controversy on how it is used. Little is known about decision-making processes regarding this procedure.

Investigational Use of Real-World Data as a Hybrid Control in Pancreatic Ductal Adenocarcinoma from the Randomized Phase Ib/II MORPHEUS Trial.

Enrolling adequate numbers of patients into the control arm of randomized controlled trials (RCTs) often presents barriers. There is interest in leveraging real-world data (RWD) from electronic health records (EHRs) to construct external control (EC) arms to supplement RCT control arms and form hybrid control (HC) arms. This investigation showed the use of an HC arm in second-line metastatic pancreatic ductal adenocarcinoma (PDAC).

The complement system in clinical oncology: Applications, limitations and challenges.

The complement system, a key component of innate immunity, is involved in seemingly contradictory aspects of tumor progression and cancer therapy. It can act as an immune effector against cancer and modulate the antitumor activity of certain therapeutic antibodies, but it can also contribute to a tumor-promoting microenvironment. Understanding this dual role should lead to the development of better therapeutic tools, strategies for cancer treatment and biomarkers for the clinical management of cancer patients.

Expression profile of Bcl-2 family proteins in newly diagnosed multiple myeloma patients.

Antiapoptotic Bcl-2 family proteins are involved in myeloma cell survival. To date, their expression in multiple myeloma (MM) patients has mostly been analyzed at the RNA level. In the present study, we quantified for the first time the protein expression of the Bcl2-family members using a capillary electrophoresis immunoassay in 120 newly diagnosed MM patients, aged ≤65 years, treated in the context of the PETHEMA/GEM2012 study.

The C5a/C5aR1 axis promotes migration of tolerogenic dendritic cells to lymph nodes, impairing the anticancer immune response.

The precise mechanisms by which the complement system contributes to the establishment of an immunosuppressive tumor microenvironment (TME) and promotes tumor progression remain unclear. In this study, we investigated the expression and function of complement C5a receptor 1 (C5aR1) in human and mouse cancer-associated dendritic cells (DCs). First, we observed an overexpression of C5aR1 in tumor-infiltrating DCs, compared to DCs from blood or spleen.

High-risk cytogenetic abnormalities in multiple myeloma: PETHEMA-GEM experience.

This study examines the impact of cytogenetic abnormalities and their co-segregation on the prognosis of newly diagnosed multiple myeloma patients. The analysis included 1304 patients from four different GEM-PETHEMA clinical trials. Genetic alterations, such as t(4;14), t(14;16), del(17p), +1q, and del(1p), were investigated using FISH on CD38 purified plasma cells.

Neutralizing GDF-15 can overcome anti-PD-1 and anti-PD-L1 resistance in solid tumours.

Cancer immunotherapies with antibodies blocking immune checkpoint molecules are clinically active across multiple cancer entities and have markedly improved cancer treatment. Yet, response rates are still limited, and tumour progression commonly occurs. Soluble and cell-bound factors in the tumour microenvironment negatively affect cancer immunity.

Can Morphology and Immune Infiltration Predict the Homologous Recombination Deficiency Status in Newly Diagnosed High-Grade Serous Ovarian Carcinoma?

Context.—: A correlation between the morphology of ovarian high-grade serous carcinomas (HGSOCs) and BRCA mutations has been previously reported.

HER2-related biomarkers predict clinical outcomes with trastuzumab deruxtecan treatment in patients with HER2-expressing metastatic colorectal cancer: biomarker analyses of DESTINY-CRC01.

DESTINY-CRC01 (NCT03384940) was a multicentre, open-label, phase 2 study that investigated the safety and efficacy of trastuzumab deruxtecan (T-DXd) in patients with human epidermal growth factor receptor 2 (HER2)-expressing metastatic colorectal cancer (CRC). The present exploratory biomarker analysis aims to investigate relationships between biomarkers and clinical outcomes in patients with HER2-positive (immunohistochemistry [IHC] 3+ or IHC 2+ and in situ hybridization [ISH] positive) Cohort A (N = 53) of DESTINY-CRC01. Higher levels of HER2 biomarkers in baseline tissue and liquid biopsies, including HER2 status (IHC/ISH), HER2/CEP17 ratio, HER2 ISH signals, HER2 H-score, plasma HER2 (ERBB2) amplification status, HER2 adjusted plasma copy number, and HER2 extracellular domain correlate with antitumor activity (indicated by objective response rate, progression-free survival, and overall survival) of T-DXd.

Prognostic value of circulating tumor DNA in different cancer types detected by ultra-low-pass whole-genome sequencing. A systematic review and patient-level survival data meta-analysis.

Ultra-low-pass whole-genome sequencing (ULP-WGS) (≤0.5× coverage) of plasma cell-free DNA (cfDNA) has emerged as a low-cost promising tool to assess circulating tumor DNA (ctDNA) fraction. This meta-analysis aims to summarize the current findings and comprehensively investigate the prognostic value of baseline ctDNA detected by ULP-WGS in solid tumors.

Clinical significance of complete remission and measurable residual disease in relapsed/refractory multiple myeloma patients treated with T-cell redirecting immunotherapy.

The impact of measurable residual disease (MRD) in relapse/refractory multiple myeloma (RRMM) patients treated with T-cell redirecting immunotherapy is uncertain. We analyzed MRD dynamics using next-generation flow in 201 patients treated in clinical trials with chimeric antigen receptor (CAR) T cells and T-cell engagers (TCE). Achieving MRD negativity at 10 was associated with 89% reduction in the risk of progression and/or death.

Prognostic risk and survival of asymptomatic IgM monoclonal gammopathy: Results from a Spanish Multicenter Registry.

Asymptomatic IgM gammopathy encompasses IgM monoclonal gammopathy of undetermined significance (MGUS) and asymptomatic Waldenström macroglobulinemia (AWM), both having a risk of progression to symptomatic disease. Here, we assessed the risk of progression and the mortality of 956 patients with asymptomatic IgM gammopathy across 25 Spanish centers. After a median follow-up of 5.

Optimizing CAR-T treatment: A TEVOLVE guide to raw and starting material selection.

Chimeric antigen receptor (CAR)-T cell products, classified as Advanced Therapy Medicinal Products (ATMPs), have shown promising outcomes in cancer immunotherapy. The quality of raw and starting materials used in manufacturing is critical to ensure the efficacy and safety of CAR-T cell products and depends primarily on the selection of the right materials and the right suppliers. It is essential to consider a long-term strategy when selecting raw and starting materials to prevent delays in the supply of innovative, high-quality, and safe therapies to patients.

Uncovering functional lncRNAs by scRNA-seq with ELATUS.

Long non-coding RNAs (lncRNAs) play fundamental roles in cellular processes and pathologies, regulating gene expression at multiple levels. Despite being highly cell type-specific, their study at single-cell (sc) level is challenging due to their less accurate annotation and low expression compared to protein-coding genes. Here, we systematically benchmark different preprocessing methods and develop a computational framework, named ELATUS, based on the combination of the pseudoaligner Kallisto with selective functional filtering.
