Background: Early palliative care interventions in oncology, as recommended by international oncology societies, promote patient understanding and support decision-making. At the same time, shared decision-making models are being developed to enhance patient participation as part of a new model of patient-physician relationship. For patients with palliative needs, this participation is essential and helps to avoid futile and aggressive treatments at the end of life.

Int J Pharm

December 2024

Department of clinical pharmacy, Gustave Roussy Cancer Campus, Villejuif 94800, France; Université Paris-Saclay, CNRS, Institut des Sciences Moléculaires d'Orsay, Orsay 91405, France.

Diffuse intrinsic pontine glioma (DIPG) poses a significant treatment challenge in pediatric patients due to its aggressive nature and difficulty in crossing the blood-brain barrier with effective therapies. ONC201 (dordaviprone) shows promises in inducing apoptosis in cancer cells but suffers from poor water solubility and stability issues. Moreover, conventional solubilizing agents acceptable in formulations intended for adult patients are not suitable for pediatric use.

Oncocytic adenocarcinoma (OC) of the salivary glands is a rare and controversial entity. It was recently reclassified as "salivary carcinoma NOS and emerging entities" in the 2022 WHO classification of head and neck tumors. The lack of specific molecular alterations and its potential affiliation with other salivary gland carcinomas, such as the oncocytic mucoepidermoid carcinomas (OMEC) or the oncocytic subtype of salivary duct carcinomas (OSDC) justified this reclassification.

Article Synopsis
  • Abnormal levels of CDKN1A/p21 can lead to opposite effects in cells, either causing rapid growth in p53-deficient cancer cells or slowing growth in hematopoietic stem cells, potentially leading to bone marrow failure (BMF).
  • In Fanconi anemia (FA), p21 is overexpressed due to both p53 and the transcription factor microphthalmia (MITF), contributing to the disease's symptoms, but the exact mechanisms remain unclear.
  • The study finds that elevated p21 in FA cells is linked to chromatin changes and increased genetic instability, and that reactive oxygen species (ROS) are crucial for this overexpression, suggesting a complex interaction that worsens cell replication issues.

Head and neck squamous cell carcinoma (HNSCC) is the seventh most common type of cancer worldwide. It is mainly discovered in a locally advanced stage, but it is estimated that 40% of recurrences after the treatment of the primary disease will be in a metastatic form, with one third being oligometastatic. There is no clear consensus regarding the treatment of oligometastatic HNSCC, whether it being local treatment, systemic treatment or a combination of both.

Article Synopsis
  • The study focuses on the effectiveness and safety of second-line treatment options (docetaxel vs. alternative ARSI) for patients aged 75 and older who have metastatic castration-resistant prostate cancer (mCRPC) after failing first-line androgen receptor signaling inhibitors (ARSIs).
  • Researchers analyzed a group of 122 elderly patients, finding no significant differences in overall survival or progression-free survival when comparing those who received docetaxel to those who received an alternative ARSI.
  • The results suggest that both treatment options are similar for elderly patients, providing useful insights despite the limitations of a small and retrospective study design.

Background: [Lu]Lu-PSMA-617 (Lu-PSMA-617) prolongs radiographic progression-free survival and overall survival in patients with metastatic castration-resistant prostate cancer previously treated with androgen receptor pathway inhibitor (ARPI) and taxane therapy. We aimed to investigate the efficacy of Lu-PSMA-617 in patients with taxane-naive metastatic castration-resistant prostate cancer.

Methods: In this phase 3, randomised, controlled trial conducted at 74 sites across Europe and North America, taxane-naive patients with prostate-specific membrane antigen (PSMA)-positive metastatic castration-resistant prostate cancer who had progressed once on a previous ARPI were randomly allocated (1:1) to open-label, intravenous Lu-PSMA-617 at a dosage of 7·4 GBq (200 mCi) ± 10% once every 6 weeks for six cycles, or a change of ARPI (to abiraterone or enzalutamide, administered orally on a continuous basis per product labelling).

The autophagy-repressive tissue hormone DBI/ACBP (diazepam binding inhibitor, acyl-CoA binding protein) suppresses anorexia.

Autophagy

December 2024

Team "Metabolism, Cancer & Immunity", Centre de Recherche des Cordeliers, UMRS 1138, Inserm, Université Paris Cité, Sorbonne Université, Paris, France.

DBI/ACBP (diazepam binding inhibitor, acyl-CoA binding protein) is produced by multiple cell types and detectable in blood plasma. DBI acts on GABRA (gamma-aminobutyric acid type A receptor) complexes containing GABRG2 (gamma-aminobutyric acid type A receptor, subunit gamma 2) to inhibit macroautophagy/autophagy and hence can be considered as an "autophagy checkpoint". In patients with poor-prognosis anorexia nervosa, as well as in mice developing stress-induced anorexia, circulating DBI levels are reduced.

Article Synopsis
  • Linear DNA can't hold supercoils due to its free rotation at the ends, but mammalian telomeres can because they face topological stress.
  • Previous studies observed negative supercoiling in telomeres, but positive supercoils weren't investigated until now due to the lack of proper tools.
  • New tools developed in this study revealed that replication stress and Topoisomerase 2 inhibition led to positive supercoil build-up at telomeres and the FRA3B fragile site, suggesting a model for DNA fragility.
