The cytokine Meteorin-like inhibits anti-tumor CD8 T cell responses by disrupting mitochondrial function.

Tumor-infiltrating lymphocyte (TIL) hypofunction contributes to the progression of advanced cancers and is a frequent target of immunotherapy. Emerging evidence indicates that metabolic insufficiency drives T cell hypofunction during tonic stimulation, but the signals that initiate metabolic reprogramming in this context are largely unknown. Here, we found that Meteorin-like (METRNL), a metabolically active cytokine secreted by immune cells in the tumor microenvironment (TME), induced bioenergetic failure of CD8 T cells.

Prognostic role of sodium levels in colorectal cancer patients receiving aflibercept plus FOLFIRI.

To investigate the impact of natremia in metastatic colorectal cancer (mCRC) patients treated with aflibercept plus folinic acid, 5-fluorouracil, oxaliplatin and irinotecan (FOLFIRI). A total of 84 mCRC patients receiving aflibercept plus FOLFIRI as second-line treatment were enrolled and divided into two groups based on their median sodium value. Progression-free survival and overall survival were analyzed.

Prognostic value of alkaline phosphatase and gamma-glutamyl transferase in patients with metastatic pancreatic cancer.

Pancreatic cancer (PC) is one of the most lethal malignancies worldwide. This study evaluated the prognostic role of serum alanine phosphatase (ALP) and gamma-glutamyl-transferase (GGT) in metastatic PC patients. 153 patients with metastatic PC receiving first-line treatment with nab-paclitaxel/gemcitabine were retrospectively enrolled in a multicenter study and stratified according to ALP (≤ or >260 U/l) and GGT (≤ or >45.

Clinical outcome and safety profile of metastatic pancreatic cancer patients treated with more than six cycles of nab-paclitaxel plus gemcitabine.

The phase III MPACT trial demonstrated the superiority of gemcitabine plus nab-paclitaxel (NABGEM) versus gemcitabine alone in previously untreated patients with metastatic pancreatic cancer (mPC). The aim of this study was to evaluate the responses in terms of efficacy and safety in patients treated with more than 6 cycles of chemotherapy. From January 2015 to December 2018, patients with mPC receiving first-line treatment with NABGEM were included in a multicentre retrospective observational study.

γδ-Enriched CAR-T cell therapy for bone metastatic castrate-resistant prostate cancer.

Immune checkpoint blockade has been largely unsuccessful for the treatment of bone metastatic castrate-resistant prostate cancer (mCRPC). Here, we report a combinatorial strategy to treat mCRPC using γδ-enriched chimeric antigen receptor (CAR) T cells and zoledronate (ZOL). In a preclinical murine model of bone mCRPC, γδ CAR-T cells targeting prostate stem cell antigen (PSCA) induced a rapid and significant regression of established tumors, combined with increased survival and reduced cancer-associated bone disease.

Use of phage display biopanning as a tool to design CAR-T cells against glioma stem cells.

Background: Glioblastoma (GBM) is both the most common and aggressive type of primary brain tumor, associated with high mortality rates and resistance to conventional therapy. Despite recent advancements in knowledge and molecular profiling, recurrence of GBM is nearly inevitable. This recurrence has been attributed to the presence of glioma stem cells (GSCs), a small fraction of cells resistant to standard-of-care treatments and capable of self-renewal and tumor initiation.

Enhanced T cell effector activity by targeting the Mediator kinase module.

T cells are the major arm of the immune system responsible for controlling and regressing cancers. To identify genes limiting T cell function, we conducted genome-wide CRISPR knockout screens in human chimeric antigen receptor (CAR) T cells. Top hits were and , components of the Mediator kinase module.

Development of anti-somatostatin receptors CAR T cells for treatment of neuroendocrine tumors.

Background: Neuroendocrine tumors (NETs) overexpress somatostatin receptors (SSTRs).

Methods: We developed a second-generation, ligand-based, anti-SSTR chimeric antigen receptor (CAR) incorporating the somatostatin analog octreotide in its extracellular moiety.

Results: Anti-SSTR CAR T cells exerted antitumor activity against SSTR+NET cell linesin vitro.

Extrafollicular Plasmablasts Present in the Acute Phase of Infections Express High Levels of PD-L1 and Are Able to Limit T Cell Response.

During infections with protozoan parasites or some viruses, T cell immunosuppression is generated simultaneously with a high B cell activation. It has been described that, as well as producing antibodies, plasmablasts, the differentiation product of activated B cells, can condition the development of protective immunity in infections. Here, we show that, in infection, all the plasmablasts detected during the acute phase of the infection had higher surface expression of PD-L1 than other mononuclear cells.

The impact of age, performance status and comorbidities on nab-paclitaxel plus gemcitabine effectiveness in patients with metastatic pancreatic cancer.

Few studies have evaluated the impact of risk factors such as performance status (PS) and comorbidities on overall survival (OS) in patients with metastatic pancreatic cancer (mPC). We investigated the influence of comorbidity, PS and age on nab-paclitaxel and gemcitabine (NabGem) effectiveness profile in naive patients with mPC. 153 patients with mPC treated with NabGem upfront was divided in three groups (score 0 to 3) based on the absence or the presence of one or more risk factors among: age ≥ 70 years, PS 1 and comorbidities and the clinical outcomes was compared.

Risk Factors for Nab-Paclitaxel and Gemcitabine-Induced Peripheral Neuropathy in Patients with Pancreatic Cancer.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most frequent adverse events observed with taxane use, whose disability often required modification or treatment discontinuation. The aim of this study was to assess the value of several variables as risk factors for CIPN development.

Material And Methods: Eligible patients with metastatic pancreatic cancer receiving chemotherapy with nab-paclitaxel and gemcitabine were assessed in a multicenter study.

Polyfunctional KLRG-1CD57 Senescent CD4 T Cells Infiltrate Tumors and Are Expanded in Peripheral Blood From Breast Cancer Patients.

Senescent T cells have been described during aging, chronic infections, and cancer; however, a comprehensive study of the phenotype, function, and transcriptional program of this T cell population in breast cancer (BC) patients is missing. Compared to healthy donors (HDs), BC patients exhibit an accumulation of KLRG-1CD57 CD4 and CD8 T cells in peripheral blood. These T cells infiltrate tumors and tumor-draining lymph nodes.

Association between Low-Grade Chemotherapy-Induced Peripheral Neuropathy (CINP) and Survival in Patients with Metastatic Adenocarcinoma of the Pancreas.

The combination of nab-paclitaxel and gemcitabine demonstrated greater efficacy than gemcitabine alone but resulted in higher rates of chemotherapy-induced peripheral neuropathy (CINP) in patients with metastatic pancreatic cancer (mPC). We aimed to evaluate the correlation between the development of treatment-related peripheral neuropathy and the efficacy of nab-P/Gem combination in these patients. mPC patients treated with nab-paclitaxel 125 mg/m and gemcitabine 1000 mg/m as a first-line therapy were included.

Association between neutropenia and survival to nab-paclitaxel and gemcitabine in patients with metastatic pancreatic cancer.

Neutropenia is a common side effect associated with nab-paclitaxel gemcitabine (Nab-Gem) therapy. We retrospectively investigated the association between neutropenia induced by first-line Nab-Gem and survival in metastatic pancreatic carcinoma patients. Metastatic pancreatic patients treated with first-line Nab-Gem were included in this retrospective analysis.

FOLFOX vs FOLFIRI as Second-line of Therapy After Progression to Gemcitabine/Nab-paclitaxel in Patients with Metastatic Pancreatic Cancer.

Background: Several progresses have been achieved for first-line chemotherapy in metastatic pancreatic ductal adenocarcinoma (PDAC) with Gem-NabP and FOLFIRINOX extensively used as standard first line regimens. However, the best second-line chemotherapy choice after progression is still not completely defined. The aim of this study is to compare effectiveness and safety of two possible second-line therapeutic options, FOLFOX and FOLFIRI, after progression to Gem-NabP.

Clinical Outcomes and Safety of Patients Treated with NAb-Paclitaxel Plus Gemcitabine in Metastatic Pancreatic Cancer: The NAPA Study.

Background: The phase III MPACT trial demonstrated the superiority of gemcitabine (Gem) combined with Nab-paclitaxel (Nab-P) versus gemcitabine alone in previously untreated patients with metastatic pancreatic ductal adenocarcinoma (PDAC). The purpose of this study was to evaluate the effect of Gem/Nab-P in routine clinical practice.

Methods: From January 2015 to December 2018, patients with metastatic PDAC receiving firstline treatment with a combination of gemcitabine and Nab-paclitaxel were included in a multicentre retrospective observational study.

The value of patient centred care in oncology.

The value of health care should be measured as the patient's well-being. This demands knowledge of patient's preference. Communication, i.

"Understanding older patients: Communication as the key step for a comprehensive approach".

Patient's frailty, attitude, life expectancy, affect the decision-making process, impacting on the following four points: 1.Disclosing the diagnosis. 2.

CAR-T Engineering: Optimizing Signal Transduction and Effector Mechanisms.

The adoptive transfer of genetically engineered T cells expressing a chimeric antigen receptor (CAR) has shown remarkable results against B cell malignancies. This immunotherapeutic approach has advanced and expanded rapidly from preclinical models to the recent approval of CAR-T cells to treat lymphomas and leukemia by the Food and Drug Administration (FDA). Ongoing research efforts are focused on employing CAR-T cells as a therapy for other cancers, and enhancing their efficacy and safety by optimizing their design.

Fertility concerns, preservation strategies and quality of life in young women with breast cancer: Baseline results from an ongoing prospective cohort study in selected European Centers.

Objectives: Most research addressing needs and concerns of young patients with breast cancer (≤40 years) is retrospective. The HOHO European protocol is a prospective multicenter cohort study of young women with newly diagnosed breast cancer, about fertility, psychosocial and quality of life concerns. Here we report the baseline data and focus on predictors of fertility concerns.

Surgical oncology in the elderly.

Poor cancer-specific outcomes in the elderly group are primarily a surgical failure. Surgeons are insufficiently trained to draw a line between fit and frail patients; this results in over-treatment of the frail patient, as well as under-treatment of the fit one. Communication skills should be improved to better understand the patient's requests.

An immunoproteomic approach to characterize the CAR interactome and signalosome.

Adoptive transfer of T cells that express a chimeric antigen receptor (CAR) is an approved immunotherapy that may be curative for some hematological cancers. To better understand the therapeutic mechanism of action, we systematically analyzed CAR signaling in human primary T cells by mass spectrometry. When we compared the interactomes and the signaling pathways activated by distinct CAR-T cells that shared the same antigen-binding domain but differed in their intracellular domains and their in vivo antitumor efficacy, we found that only second-generation CARs induced the expression of a constitutively phosphorylated form of CD3ζ that resembled the endogenous species.

IL-17RA-Signaling Modulates CD8+ T Cell Survival and Exhaustion During Infection.

The IL-17 family contributes to host defense against many intracellular pathogens by mechanisms that are not fully understood. CD8+ T lymphocytes are key elements against intracellular microbes, and their survival and ability to mount cytotoxic responses are orchestrated by several cytokines. Here, we demonstrated that IL-17RA-signaling cytokines sustain pathogen-specific CD8+ T cell immunity.
