Objective: To evaluate prognostic differences between minimally invasive esophagectomy (MIE) and open esophagectomy (OE) in patients with surgery after a prolonged interval (> 12 wk) following chemoradiotherapy (CRT). Background: Previously, we established that a prolonged interval after CRT before esophagectomy was associated with poorer longterm survival. Methods: This was an international multicenter cohort study involving 17 tertiary centers, including patients who received CRT followed by surgery between 2010 and 2020. Patients undergoing MIE were defined as thoracoscopic and laparoscopic approaches. Results: A total of 428 patients (145 MIE and 283 OE) had surgery between 12 weeks and 2 years after CRT. Significant differences were observed in American Society of Anesthesiologists grade, radiation dose, clinical T stage, and histologic subtype. There were no significant differences between the groups in age, sex, body mass index, pathologic T or N stage, resection margin status, tumor location, surgical technique, or 90-day mortality. Survival analysis showed MIE was associated with improved survival in univariate (P= 0.014), multivariate analysis after adjustment for smoking, T and N stage, and histology (HR=1.69; 95% CI: 1.14-2.5) and propensity-matched analysis (P=0.02). Further subgroup analyses by radiation dose and interval after CRT showed survival advantage for MIE in 40 to 50 Gy dose groups (HR= 1.9; 95% CI: 1.2-3.0) and in patients having surgery within 6 months of CRT (HR =1.6; 95% CI: 1.1-2.2). Conclusions: MIE was associated with improved overall survival compared with OE in patients with a prolonged interval from CRT to surgery. The mechanism for this observed improvement in survival remains unknown, with potential hypotheses including a reduction in complications and improved functional recovery after MIE.

Context. Gastric and oesophageal cancers are common. They are also expected to increase in incidence in the next few years and are characterized by poor prognosis. Surprisingly, whereas the incidence of severe anxiety and depression is high in patients with gastric and oesophageal cancers, the influence of symptoms of depression and anxiety on postoperative complications has barely been explored. Methods. In a retrospective study based on a prospectively collected database, 629 cancer patients were enrolled. Symptoms of depression and anxiety (Hospital Anxiety and Depression Scale scores) and sociodemographic and medical information were collected immediately after diagnosis and before any treatment. The surgical approach (i.e. gastrectomy or oesophagectomy) and postoperative complications according to the Clavien–Dindo classification were collected after surgery. Results. After controlling for known medical predictors (i.e. surgical strategy, alcohol and tobacco consumption, American Society of Anaesthesiologists classification physical status score) of postoperative complications, no effect of symptoms of depression or anxiety was detected. Discussion. The observed results are surprising given the literature. However, several potential arguments can be put forwards regarding methods and measures, controlling variables, and conceptual distinctions. Despite the absence of significant results, this topic should be more deeply investigated by applying methodological and conceptual adjustments. [ABSTRACT FROM AUTHOR]
