Prognostic significance of T-cellâinflamed gene expression profile and PD-L1 expression in patients with esophageal cancer
PURPOSE: The ability of the Tâcellâinflamed gene expression profile (GEP) to predict clinical outcome in esophageal cancer (EC) is unknown. This retrospective observational study assessed the prognostic value of GEP and programmed death ligand 1 (PDâL1) expression in patients with EC treated in routine clinical practice. METHODS: Tumor samples of 294 patients from three centers in Denmark, South Korea, and the United States, collected between 2005 and 2017, were included. Tâcellâinflamed GEP score was defined as nonâlow or low using a cutoff of â1.54. A combined positive score (CPS) âĽ10 was defined as PDâL1 expression positivity. Associations between overall survival (OS) and GEP status and PDâL1 expression were explored by Cox proportional hazards models adjusting for age, sex, histology, stage, and performance status. RESULTS: Median age was 65 years; 63% of patients had adenocarcinoma (AC) and 37% had squamous cell carcinoma (SCC). Thirtyâsix percent of tumors were GEP nonâlow, with higher prevalence in AC (46%) than SCC (18%). Twentyâone percent were PDâL1âpositive: 32% in South Korean samples versus 16% in nonâAsian samples and 26% in SCC versus 18% in AC. GEP scores and PDâL1 CPS were weakly correlated (Spearmanâs R = 0.363). OS was not significantly associated with GEP status (nonâlow vs low; adjusted hazard ratio, 0.91 [95% CI, 0.69â1.19]) or PDâL1 expression status. CONCLUSION: Neither GEP nor PDâL1 expression was a prognostic marker in Asian and nonâAsian patients with EC
Patient blood management knowledge and practice among clinicians from seven European university hospitals : a multicentre survey
Background and Objectives The aim of this survey was to evaluate the knowledge about Patient Blood Management (PBM) principles and practices amongst
clinicians working in seven European hospitals participating in a European Blood
Alliance (EBA) project.
Materials and Methods A web-based questionnaire was sent to 4952 clinicians
working in medical, surgery and anaesthesiology disciplines. The responses were analysed, and the overall results as well as a comparison between hospitals are presented.
Results A total of 788 responses (16%) were obtained. About 24% of respondents
were not aware of a correlation between preoperative anaemia (POA) and perioperative morbidity and mortality. For 22%, treatment of POA was unlikely to favourably
influence morbidity and mortality even before surgery with expected blood loss. More
than half of clinicians did not routinely treat POA. 29%, when asked which is the best
way to treat deficiency anaemia preoperatively, answered that they did not have sufficient knowledge and 5% chose to âdo nothingâ. Amongst those who treated POA, 38%
proposed red cell transfusion prior to surgery as treatment. Restrictive haemoglobin
triggers for red blood cell transfusion, single unit policy and reduction of number and
volumes of blood samples for diagnostic purposes were only marginally implemented.
Conclusion Overall, the responses indicated poor knowledge about PBM. Processes to diagnose and treat POA were not generally and homogeneously implemented. This survey should provide further impetus to implement programmes to
improve knowledge and practice of PBMpeer-reviewe
