Background: Nodes are the second site for prostate cancer recurrence. Whole-pelvic radiotherapy (WPRT) has shown superiority over nodal stereotactic body radiotherapy (SBRT) in two retrospective cohorts. We aimed to compare both modalities and assess factors associated with treatment outcomes.

Objective: To assess rates and trends of hospitalizations and emergency department (ED) visits related to MH and self-harm (SH) among children before and during the 3 years following the pandemic onset.
Article Synopsis
- Salvage radiation therapy (sRT) is crucial for patients who experience biochemical recurrence after prostate surgery, and a new nomogram has been developed to predict their chances of remaining free from this recurrence.
- * This study aims to evaluate the effectiveness of PSMA-PET-based assessments in guiding sRT for cases of prostate-specific antigen (PSA) persistence or recurrence, and it seeks to improve predictive models using random survival forests compared to traditional Cox models.
- * Data from 1029 patients across five countries were analyzed to validate these predictive models, utilizing machine learning techniques to better understand outcomes related to biochemical failure after treatment.
Introduction: General Practitioners (GPs) play a key role of gatekeeper, as they coordinate patients' care. However, most of them reported having difficulty to refer patients to hospital, especially in semi-urgent context. To facilitate the referral of semi-urgent patients, we implemented an e-referral platform, named SIPILINK, within 4 wards from a large public French hospital (internal medicine, diabetology, gynaecological surgery and oncology wards).

Summary Background Data: New thresholds in digestive cancer surgery were applied in 2023, accrediting centers for major interventions. No evidence has been provided to support their justification.
