Article Synopsis
  • Immunotherapy, particularly when combined with chemotherapy, has shown limited effectiveness against solid tumors due to factors like cancer cells promoting immune cell exhaustion through nutrient diversion in the tumor microenvironment (TME).
  • The authors suggest using high doses of sodium citrate (SCT) alongside immune checkpoint inhibitors (ICIs) to inhibit cancer cell metabolism and enhance anti-tumor immune responses, as preclinical studies indicate SCT can reduce cancer growth and improve chemotherapy outcomes.
  • SCT works by increasing available glucose for immune cells and lowering lactic acid levels in the TME, which may enhance T cell activity and repolarize macrophages, indicating its potential to significantly boost the effectiveness of current immunotherapies in clinical settings.

Background: Suspected upper gastrointestinal bleeding (SUGIB) is a common issue during ICU stay. In the absence of specific guidelines on the indication and timing of esophagogastroduodenoscopy (EGD), there is substantial variability in EGD indication depending on accessibility and clinical presentation. This study aimed to investigate factors associated with the need for per-EGD hemostatic therapy and to create a score predicting therapeutic benefit of emergency bedside EGD in ICU patients with SUGIB.

NSCLC is the leading cause of cancer mortality and represents a major challenge in cancer therapy. Intrinsic and acquired anticancer drug resistance are promoted by hypoxia and HIF-1α. Moreover, chemoresistance is sustained by the activation of key signaling pathways (such as RAS and its well-known downstream targets PI3K/AKT and MAPK) and several mutated oncogenes (including KRAS and EGFR among others).

Background: Immune checkpoint inhibitor (ICPi) rechallenge could represent an attractive option in non-small-cell lung cancer (NSCLC), yet no sufficient data supporting this strategy are available. This retrospective observational multicenter national study explored the efficacy of anti-programmed cell death 1 (PD-1)/programmed death ligand 1 (PD-L1) rechallenge in advanced NSCLC patients, looking for potential clinical features associated with greater outcomes.

Patients And Methods: We retrospectively collected data from 144 advanced NSCLC patients whose disease was rechallenged with ICPis after ≥ 12 weeks of discontinuation.

Inserm, Cordeliers Research Center, U1138, eq 22, Paris Descartes University, Sorbonne Paris-Cite, Paris, France; Department of Medical Informatics, Necker-Enfants Malades Hospital, Assistance Publique-Hôpitaux de Paris (AP-HP), Paris, France.

With the emergence of electronic health records, the reuse of clinical data offers new perspectives for the diagnosis and management of patients with rare diseases. However, there are many obstacles to the repurposing of clinical data. The development of decision support systems depends on the ability to recruit patients, extract and integrate the patients' data, mine and stratify these data, and integrate the decision support algorithm into patient care.

Herpes simplex virus-1 (HSV-1) encephalitis (HSE) is typically sporadic. Inborn errors of TLR3- and DBR1-mediated central nervous system cell-intrinsic immunity can account for forebrain and brainstem HSE, respectively. We report five unrelated patients with forebrain HSE, each heterozygous for one of four rare variants of SNORA31, encoding a small nucleolar RNA of the H/ACA class that are predicted to direct the isomerization of uridine residues to pseudouridine in small nuclear RNA and ribosomal RNA.

The number of clinical protocols testing combined therapies including immune check-point inhibitors and platinum salts is currently increasing in lung cancer treatment, however preclinical studies and rationale are often lacking. Here, we evaluated the impact of cisplatin treatment on PD-L1 expression analyzing the clinicopathological characteristics of patients who received cisplatin-based neoadjuvant chemotherapy followed by surgery and showed that cisplatin-based induction treatment significantly increased PD-L1 staining in both tumor and immune cells from the microenvironment. Twenty-two patients exhibited positive PD-L1 staining variation after neoadjuvant chemotherapy; including 9 (23.

November 2019

Thoracic Surgery Department, Paris Center University Hospital, Assistance Publique - Hôpitaux de Paris, Paris Descartes University, Paris, France. Electronic address:

Introduction: Adrenal gland metastases occur in up to 20% of patients with non-small-lung cancer. In selected cases with limited burden of disease, surgery may be offered to improve patient outcome; furthermore, tissue analysis would provide useful information on genotype of primary and secondary neoplasms.

Materials And Methods: We report our experience in the management of adrenal metastasis by retrospectively reviewing data of 21 consecutive patients treated with curative intent to the primary tumor followed by adrenalectomy in a 15-year time span.

Cell cycle progression and division is regulated by checkpoint controls and sequential activation of cyclin-dependent kinases (CDKs). Understanding of how these events occur in synchrony with metabolic changes could have important therapeutic implications. For biosynthesis, cancer cells enhance glucose and glutamine consumption.

How the Warburg effect supports aggressiveness and drug resistance of cancer cells?

May 2018

Inserm U1052, CNRS UMR5286, Centre de Recherche en Cancérologie de Lyon (CRCL), France; Université Lyon Claude Bernard 1, Lyon, France; ISPB, Faculté de Pharmacie, Lyon, France. Electronic address:

Cancer cells employ both conventional oxidative metabolism and glycolytic anaerobic metabolism. However, their proliferation is marked by a shift towards increasing glycolytic metabolism even in the presence of O (Warburg effect). HIF1, a major hypoxia induced transcription factor, promotes a dissociation between glycolysis and the tricarboxylic acid cycle, a process limiting the efficient production of ATP and citrate which otherwise would arrest glycolysis.
