Integrative study of skeletal muscle mitochondrial dysfunction in a murine pancreatic cancer-induced cachexia model.

Pancreatic ductal adenocarcinoma (PDAC), the most common pancreatic cancer, is a deadly cancer, often diagnosed late and resistant to current therapies. PDAC patients are frequently affected by cachexia characterized by muscle mass and strength loss (sarcopenia) contributing to patient frailty and poor therapeutic response. This study assesses the mechanisms underlying mitochondrial remodeling in the cachectic skeletal muscle, through an integrative exploration combining functional, morphological, and omics-based evaluation of gastrocnemius muscle from KIC genetically engineered mice developing autochthonous pancreatic tumor and cachexia.

Inotuzumab Ozogamicin and Low-Intensity Chemotherapy in Older Patients With Newly Diagnosed CD22 Philadelphia Chromosome-Negative B-Cell Precursor Acute Lymphoblastic Leukemia.

Purpose: The use of inotuzumab ozogamicin (InO), a conjugated anti-CD22 monoclonal antibody, is becoming a promising frontline treatment for older patients with ALL.

Patients And Methods: EWALL-INO is an open-label prospective multicenter phase II trial (ClinicalTrials.gov identifier: NCT03249870).

Eligibility for Adjuvant Cyclin-Dependent Kinase 4/6 Inhibitors in Endocrine Receptor-Positive and HER2-Negative Early Breast Cancer by Age and Type of Surgery.

Despite early diagnosis, approximately 20% of patients with ER-positive and HER2-negative breast cancer (BC) will experience disease recurrence. Improved survival has been reported with adjuvant treatment combining cyclin-dependent kinase 4/6 inhibitors with endocrine therapy, in high-risk patients with ER-positive and HER2-negative BC, regardless of age. Older patients have higher rates of ER-positive/HER2-negative BC than younger patients.

Brain metastases reirradiation.

The advances in cancer screening and therapies have allowed the improvement of metastatic patients' survival, including those with brain metastases. This led to a substantial shift in brain metastases patients' management for whom whole-brain radiation therapy, formerly widely used, has given way to a more focused management in which single- or multifractionated stereotactic radiation therapy now plays a predominant role. Although stereotactic radiation therapy offers excellent local control rates (70 to 90%), it does not prevent brain recurrence outside the radiation field, which is all the more frequent the higher the number of initial metastases and the longer the patient's survival.

Reactive oxygen species and aldehyde dehydrogenase 1A as prognosis and theragnostic biomarker in acute myeloid leukaemia patients.

Acute myeloid leukaemia (AML) remains a major unmet medical, despite recent progress in targeted molecular therapies. One aspect of leukaemic cell resistance to chemotherapy is the development of clones with increased capacity to respond to cellular stress and the production of reactive oxygen species (ROS), thanks in particular to a high aldehyde dehydrogenases (ALDH) 1A1/2 activity. At diagnosis, ROS level and ALDH1A1/2 activity in AML patients BM are correlated with the different ELN 2022 prognostic groups and overall survival (OS).

Follicular lymphoma comprises germinal center-like and memory-like molecular subtypes with prognostic significance.

A robust prognostic and biological classification for newly diagnosed follicular lymphoma (FL) using molecular profiling remains challenging. FL tumors from patients treated in the RELEVANCE trial with rituximab-chemotherapy (R-chemo) or rituximab-lenalidomide (R2) were analyzed using RNA sequencing, DNA sequencing, immunohistochemistry (IHC), and/or fluorescence in situ hybridization. Unsupervised gene clustering identified 2 gene expression signatures (GSs) enriched in normal memory (MEM) B cells and germinal center (GC) B-cell signals, respectively.

Case Series: Variants in Four Patients with Metastatic Pheochromocytoma.

Few reports have highlighted the rare presence of somatic variants in clinically aggressive, metastatic pheochromocytoma/paraganglioma (PCC/PGL); however, none have addressed detailed clinical presentation (including biochemistry and imaging) and management of these patients. Here, we address these clinical features and management based on four PCC patients with somatic variants from our National Institutes of Health PCC/PGL cohort. A total of 192 patients underwent exome sequencing (germline, somatic, or both), and four males were found to have somatic variants (with additional somatic and oncogenic variants in patients 2 and 4, respectively).

BTN2A1 targeting reprograms M2-like macrophages and TAMs via SYK and MAPK signaling.

Tumor-associated macrophages (TAMs), often adopting an immunosuppressive M2-like phenotype, correlate with unfavorable cancer outcomes. Our investigation unveiled elevated expression of the butyrophilin (BTN)2A1 in M2-like TAMs across diverse cancer types. We developed anti-BTN2A1 monoclonal antibodies (mAbs), and notably, one clone demonstrated a robust inhibitory effect on M2-like macrophage differentiation, inducing a shift toward an M1-like phenotype both in vitro and ex vivo in TAMs from patients with cancer.

Oncologic surveillance after surgical treatment for clinically localized kidney cancer: UroCCR study n. 129.

Background: In 2021, the EAU Guidelines implemented a novel, expert opinion-based follow-up scheme, with a three-risk-category system for clear cell (cc) and non-cc renal cell carcinoma (non-ccRCC) after surgery with curative intent. We aimed to validate the novel follow-up scheme and provide data-driven recurrence estimates according to risk groups, to confirm or implement the oncologic surveillance strategy.

Methods: We identified 5,320 patients from a prospectively maintained database involving 28 French referral centers.

Detective flow imaging contrast-enhanced EUS in solid pancreatic lesions.

Background And Objectives: Detective flow imaging EUS (DFI-EUS) is a new technology that detects fine vessels and low-flow velocity without contrast agents, used in real time during EUS, with a better resolution compared to usual technologies such as color Doppler and eFLOW. The aim of this study was to compare DFI-EUS with contrast-enhanced EUS (CE-EUS) for the evaluation of vascularization in solid pancreatic lesions.

Methods: We included patients who had a pancreatic mass visualized by EUS, with recorded images of their assessment in DFI-EUS and CE-EUS techniques and a histological diagnosis confirmed malignant tumors or a minimum of 1-year follow-up for benign lesions.

Dynamic changes in mutated circulating tumor DNA predicts outcome of patients with high-grade ovarian carcinomas.

There is a lack of biomarkers to predict outcome following initial treatment in patients with high-grade ovarian cancer. We hypothesized that monitoring mutation () in circulating tumor DNA (ctDNA) could be a tumor-specific biomarker. Patients enrolled in a prospective study (NCT03010124) consented to analysis of biological samples through the disease course.

Sexual health and emotional wellbeing of patients with haematological malignancies: general review.

Sexual health is an important aspect of a person's life. Many patients and haematologists believe that intimacy and sexuality issues are substantial during cancer treatment. The haematological cancer disease, diagnosis, shock of the announcement, treatment, and follow-up appointments, can all have negative effects on the quality of life of patients, their partners, other family members, and friends.

Targeting BTN2A1 Enhances Vγ9Vδ2 T-Cell Effector Functions and Triggers Tumor Cell Pyroptosis.

Vγ9Vδ2 T cells are potent but elusive cytotoxic effectors. Butyrophilin subfamily 2 member A1 (BTN2A1) is a surface protein that has recently been shown to bind the Vγ9 chain of the γδ T-cell receptor, but its precise role in modulating Vγ9Vδ2 T-cell functions remains unknown. Here, we show that 107G3B5, a monoclonal BTN2A1 agonist antibody, was able to significantly enhance Vγ9Vδ2 T-cell functions against hematologic or solid cell lines and against primary cells from patients with adult acute lymphoblastic leukemia.
