Background: Discharge against medical advice (DAMA) disrupts continuity of care and is associated with increased readmission rates, morbidity, and mortality. While extensively studied in general hospital populations, its prevalence and associated factors in cancer patients, where treatment adherence is critical for outcomes, remain underexplored.

Methods: This multicenter, cross-sectional study analyzed anonymized data from the IQVIA hospital database, including cancer patients hospitalized in 36 German hospitals between January 2019 and December 2023.

Background: Circulating tumour cells (CTCs) and tumour-derived extracellular vesicles (tdEVs) have great potential for monitoring therapy response and early detection of tumour relapse, facilitating personalized adjuvant therapeutic strategies. However, their low abundance in peripheral blood limits their informative value. In this study, we explored the presence of CTCs and tdEVs collected intraoperatively from a tumour-draining vein (DV) and via a central venous catheter (CVC) prior to tumour resection.

The aim of this study was to investigate the incidence of depression in patients with these pathologies and to highlight the need to address the psychosocial aspects of these diseases.

While historically diagnosed based on this classic triad of symptoms, current understanding reveals a more nuanced presentation. This study aimed to investigate the prevalence of PA-associated diseases in a large German population.

Radioiodine (RAI) therapy after surgery, is an important component for the treatment of patients with papillary thyroid cancer (PTC), the most common thyroid cancer. In this study we sought to evaluate the cancer-specific survival (CSS) impact of RAI in specific thyroid cancer subgroups. The Surveillance, Epidemiology, and End Results (SEER) database were used to identify patients with PTC who underwent surgery between 2000 and 2019.
