Textbook outcome after esophagectomy: A retrospective study from a high-volume center.

BACKGROUND: Textbook outcome is a composite quality measurement in esophageal cancer surgery. This study aimed to estimate the rate of textbook outcome esophagectomies at a high-volume center and investigate associations between textbook outcome and overall and recurrence-free survival. METHODS: A retrospective single-center study was conducted at Copenhagen University Hospital, Rigshospitalet, Denmark, analyzing esophagectomies performed from November 1, 2016, to December 31, 2021. Patients with primary carcinoma of the gastroesophageal junction who underwent elective and curative esophagectomy were included. The rate of textbook outcome esophagectomies was calculated, and the impact of textbook outcome on overall and recurrence-free survival was analyzed using Kaplan-Meier and Cox regression. RESULTS: A total of 433 patients were included in the study. Textbook outcome was achieved in 195 patients (45%). Achieving textbook outcome was independently associated with improved overall survival (HR 0.67; P = .011) and with a median overall survival of 57 months and 32 months for patients with or without textbook outcome, respectively. A trend for improved recurrence-free survival was observed for patients with textbook outcome (HR 0.74; P = .064). CONCLUSION: The present study found a consensus-based textbook outcome rate of 45%. Textbook outcome was found to be directly associated with improved overall survival. These results emphasize the association between improved short-term outcomes and long-term survival.

The Prognostic Value of Plasma Small Extracellular Vesicles' Phenotype in Patients With Gastrointestinal Stromal Tumor.

BACKGROUND/AIM: For patients with local gastrointestinal stromal tumor (GIST), risk stratification is used to assess the prognosis and identify patients to offer adjuvant treatment. For patients with advanced or metastatic GIST, no such risk stratification exists. This study aimed to investigate the prognostic value of 31 different plasma small extracellular vesicles' (SEVs) surface proteins in GIST patients. MATERIALS AND METHODS: GIST patients from the two sarcoma centers in Denmark were included. Patients were divided into three groups; group 1: patients undergoing radical surgery; group 2: patients with local, locally advanced, or metastatic GIST; and group 3: patients without evidence of disease after radical surgery. Protein microarray technology was used for the analysis of plasma SEVs. The median plasma SEV marker level was used when comparing groups of patients. The primary endpoint was the progression of GIST. Iterative statistical modeling was used to identify a SEV marker profile/model with a prognostic value. RESULTS: A total of 157 patients were included, with a median follow-up time of 2.05 years. In group 2, a high level of carcinoembryonic antigen (CEA) and a low level of glucose transporter 1 (GLUT-1) were found to be poor prognostic factors [univariate analysis; GLUT-1: hazard ratio (HR)=0.47, 95% confidence interval (CI)=0.22-0.98; CEA: HR=2.12, 95%CI=1.02-4.44]. Composing a model consisting of CEA and GLUT-1 adjusted for age at inclusion was found to have a prognostic value (HR=4.93, 95%CI=2.30-10.57, p<0.0001). CONCLUSION: Plasma SEVs in GIST showed that CEA and GLUT-1 might be of prognostic value. However, external validation is needed.
